CONNER AND BENJAMIN F. CONNER, OE NEIV YORK, N. Y. TYPE-FINISHING MACHINE. SPECIFICATION forming part of Letters Patent No. 484,915, dated October 25, 1892. Application tiled August 20, 1891. Serial No. 403,154. (No model.) To all whom it 'may concern,.- Be it known that 1, THOMAS M. KENNEY, of Cambridge, county of Middlesex, State of Massachusetts, have invented an Improvement in Type-Finishing Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts. My invention relates to a machine for finishing type after casting by removing the projecting fins and sprue-marks that are left on the type by the mold. This work has usually been done by hand by rubbing the four sides of the body of the type on a grinding-surface, so as to remove all parts that project beyond the four sides of the body of the type, although attempts have been made to perform this work by machinery, usually by forcing the type against one or more stationary cutters, which trim off the projecting parts on one or more sides, or by the employment of reciprocating or rotating files or abradingsurfaces that operate upon a pair of opposite faces of a number of type simultaneously. Such machines have not, however, proved satisfactory in practice and have not been generally adopted. The present invention is embodied in a machine having pairs of rotary cutters between which the type are passed successively in longitudinal direction, the space between each pair of cutters being equal to the thickness of the body of the type in one direction, so that the type passing between said cutters has all the projecting portions on two faces removed. There are two pairs of said rotating cutters, one to trim one pair of opposite faces of the body of the type and the other to trim the other pair of faces, and it is necessary either that the two parts of cutters should turn about axes at right angles one to the other, or that the type should be turned quarter around its longitudinal axis in passing from one pair of cutters to the other, so that each pair may act upon the proper faces of the type. As shown in this instance, the type are fed to the cutters partly by gravity and partly by feed-wheels, and both pairs of cutters and feed-wheels turn about a horizontal axis, the type receiving an axial quarter-turn in passing from one pair of cutters to the next. Means are provided for adjusting the distance between the cutters, so that they may act upon type of different size, and as the thickness of the typeshank in one direction-that is, in line with the height of the letter of the type-is the same for an entire font of type one pair of cutters will need to be adjusted only for each new font, while the other pair will have to be adjusted for type of different thickness in the saine font used for the different letters and characters. The rotating cutters are provided with cutting teeth or edges at their peripheries, which act to shear off the parts that project from the type-body, thus having a cleaner and more uniform action than cutters in the nature of tiles, which have an abrading action upon the entire exposedsnrface of the type at once. A carrier is provided which takes the type one at a time as they come from the cutters and places them in upright position side by side in a guideway, through which the column is pressed by the successively-entering type and caused to pass over a saw or cutter which removes the sprite-marks from the bottom of the type. In working the machine the type are fed one at a time into an inclined guideway, down which they pass by gravity to the first pair of feed-wheels, which present them to the first pair of cutters, through which they are carried both by gravity and by the action of the following type presented by the feedwheels, and after leaving the first pair of cutters they pass over an inclined chute having a quarter-turn, which causes the type passing over it to be turned quarter around axially, in which position they are taken by the second pair of feed-wheels and presented to the second pair of cutters, after passing which they are taken by the carrier and placed in column in the guideway, through which they pass over the sprue-cutter and are delivered from the machine. All the type corresponding to one character or having one thickness of body are first finished, after which the upper pair of cutters are set for type or characters of another thickness, which are then passed through, and so on. Figure 1 is a side elevation of a type-finish- IOO ing machine embodying this invention; Fig. 2, a plan view thereof; Fig. 3, a central longitudinal vertical section showing the carrier and receiving-guide in side elevation; Fig. 4, a transverse vertical section on line a: m, Fig. 2; and Fig. 5, a transverse vertical section on broken line 'y y, Fig-2; Fig. 6, a detail showing the carrier detached in side elevation in the positions occupied in the operation of introducing a type `into the receiving-stick; Fig. 7, a detail showing the carrier in side e1evation, as seen from the rear of the arrowsin Fig. 1, being the opposite side to that shown in Fig. 6; Fig. 8, a detail showing, in elevation, the lower end of the bed from which the type are delivered to the carrier; Fig. 9, a sectional detail showing in plan view the stop fw, Fig. 2, and co-operating parts; Fig. l0, a detail showing a portion of the inner face of the cutting-disk that comes adjacent to the type; Fig. 11, an elevation showing a portion of the edge or periphery of the cutting-disk; Fig. 12, a sectional detail of the cutting-disk; Fig. 13, a detail showing a portion of the outer face of the cutting-disk; and Fig. 14:, a sectional detail on line z, Fig. 2. Fig. l is on a smaller scale than the remaining figures and shows the driving-shaft, which is omitted in the other figures. The working parts of the machine are sup ported on a suitable frame or bed-plate A, which may be mounted on a suitable table A3, (see Fig. 1,) ou which is supported the actuating counter-shaft a, provided with pulleys from which is driven a belt a2, that drives the pair of cutters 011 one side of the machine, and a belt 0.20, that drives the pair of cutters at the other side of the machine and also the cutter that operates to form the groove at the bottom of the type, and the belt h2, that drives the pulley b, that actuates the carrier and has connected with it a small pulley cooperating with a belt c, that drives the type-feed wheels, as will be hereinafter described. The said frame-pieceA supports an inclined bed-plate A2, on which is mounted the type-support and guidewayB, theinclination of which, as shown in Fig. 3, is sufficient to cause the type to slide from its higher to its lower end by the action of gravity. The said type-supportB is mainly in the form of a Hat table or platform, which is, however, recessed at the places where the finishing-cutters d d2 and e e2 operate, as best shown'in Fig. 3, the parts of said `table or platform B above and below each pair of cutters being connected by a U-shaped portion or bridge B2. The said cutters (see Figs. 10 to 13) are shown in this instance as each made in the form of a disk the face of which, adjacent to the type being acted upon, is plane, while the outer face is beveled near the periphery, which is notched so as to form the cutting-edges 2 in the face of the disk and cutting-edges 3 at the end of the teeth, said cutting-edges 2 and 3 thus acting only to cut oif or remove portions that project from the type-body rather than acting by attrition on the entire face of the type-body, as is the case when files or similar instruments are used for finishing the type. The type to be finished are contained in a suitable tray or reservoir C near the higher end of the supportingguide B, as shown, and the type, which are represented by the letter T, and some of which are shown in the different positions assumed in the operation Vguideway, and other guides mounted on said bed engage the sides of the body of the type, said guides, as well as the cutters, being adj ustable to co-operate with type of different widths or thicknesses of body. The first pair of said lateral guideways are represented at f, said guideways having daring ends where the type are received, as shown in Fig. 2, and slotted shank portions f2, connected with the bed-pieces Bby screws f3, thus enabling them to be set proper distance apart for the width of the type characters at any time being finished. The said guide-pieces f should be set so as to allow the type to pass freely between them, it being merely necessary to prevent possibility of the type rolling over or turning axially While passing between said guides, and the inclination of the guideway is such, as before stated, that the type will slide downward therein. The lower ends of the guidepieces fare provided with slightly-yielding fingers f4, which center the type and present the same to the first pair of feed-wheels 9,' which are a pair of slightly-yielding disks or 'flanges mounted upon a shaft g2, and one being adjustable toward and from the other ou said shaft to accommodate type of different thickness. The said feed-wheels are sufficiently yielding to enable them to beset close enough to press slightly against the opposite faces of the type and are notched or nicked around their periphery, as best/shown in Fig. 3, so as to make their edge portions more yielding, and also to provide recesses which receive the projection that is usually formed in casting at the shoulder of the type or point where the face portions join the body portion. Such projection will naturally drop into the first notches of the wheels that meet it as it travels down the guideway, after which the said wheels will have a positive action to feed the type to the cutters d d2, the cuttingteeth of which are so formed as to have cutting action both on their periphery and on their inner faces, so that they immediately cut ed all parts that project beyond the faces of the type-body as it passes between said cutters. IIO As before stated, the supporting-bed B is recessed at the points where the cutters act on the type, and it is consequently necessary to provide another floor or support for the type while passing between the cutters, which themselves constitute the side guides for the type during this part of their movement. Such support for the type is provided by means of a bridge-piece h, which is provided with tenons or projections working in grooves, as shown at h2, in the ends of the portions of the platform B, thus providing for the removal of a given bridge-piece and substitution of a wider or narrower one, as may be required when type of different size are to be finished. The said bridge-piece need not. be wide enough to completely fill the space between the cutters, and consequently a single bridge-piece may be used for type Varying considerably in thickness, so that a comparatively-small number of bridge-pieces is required to accommodate type of all sizes to be finished in the machine. The devices for supporting and actuating the type as they pass the lower part of cutters c c2 are the same as those at the upper pair of cutters d d2, and consequently are marked by the same reference-letters and do not need to be separately described. As the rotation of the feed-wheels and cutters may tend to raise the type or portions thereof from the supporting-bed or bridgepiece h, a top guide or hold-down t' is also provided, the same consisting of a thin plate supported on a shank or stem t'2, vertically adjustable in an arm 713, horizontally adjustable in a standard 114 (see Figs. 1 and 2) on the bed-piece B. If the type do not readily clear from the cutters,they will be pushed out by the following type fed by the rolls g, and from the position between the upper cutters d d2 Will slide down upon the turning-guide lo, which is substantially a V-shaped trough of sheet metal, having one side substantially in the plane of the bed B and the other side at right angles thereto at the end adjacent to the cutters d d2,the said trough being twisted axially, so that at its lower end adjacent to the cutters e e2 the side which at the upper end was parallel with the bed B is at right angles thereto, while the side at right angles to the bed at the upper end is parallel with the bed at the lower end, so that the type resting in the angle of the trough and sliding down the same from the upper to the lower end is turned axially about quarter around and presents the intermediate faces at right angles to the bed B to those which were at right angles to the bed when the type was rst applied thereto. At the lower end of the turning-guide k the type is received by a second pair of feed-wheels glo, precisely similar to the feed-wheels g that carry thetype into the upper pair of cutters, said lower feedwheels glo acting in the same manner to carry the type to the action of the lower pair of cutters c e2, which thus trim the faces of the type which were not trimmed by the upper pair of cutters. An additional adjustable guide-piece 7a2, (see Fig. 2,) near the lower end of a turningguide lo, co-ope'rates with the side of the said turning-guide, which is at right angles to the bed-plate, so as to deliver the type directly in line with the feed-wheels g10 in proper position to be received thereby. The guidepiece k2 has a slotted supporting-shank le20, which receives a fastening screw 7022, (see Fig. 14,) by which it is held in proper position relative to the turning-guide, the slot permitting it to be adjusted to co-operate with type of different widths. After passing the lower pair of cutters e c2 the type continues down the chute by gravity, and at the proper time is received upon the carrier fm, which consists of a platform pivoted at m2 so as to turn from the full to the dotted line position, Fig. 3, said platform when in full-line position being in line with the bed b, so that the type passes from said bed directly onto said platform and is received between adjustable side supports m3 thereon. Then said platform m has connected with it an arm n, operated by a link n2, (see Figs. 1 and 3,) actuated by a wrist-pin n3, rotated by the pulley b, said wrist-pin working in a slot n4 in the link n2, so as to afford lost motion, thus making the movement of the carrier m intermittent, the said carrier remaining stationary in the fullline position, Fig. 3, while the wrist-pin n3 is moving through about one-half of its path, at which time it travels up and down the slot 'n4 without movingthelinlmlongitudinally. In the upper half of its circle of movement the wrist-pin ns engages the link and throws the carrier m from the full to the dotted line position, Fig. 3, and immediately thereafter permits it to return to the full-line position again, the link n2 being drawn downward by a spring a5, as shown in Fig. l. The carrier is provided wit-h a curved apron m5, which stands across the lower end of the chute or guideway on the bed B when theV carrier is moved from the full to the dotted line position, and thus arrests any type that may follow the one being conveyed by said carrier until said carrier returns to its fullline position, when said type will drop by gravity onto the carrier, which is of proper length to receive one type only at a time. When the carrier is moved to the dotted-line position, Fig. 3, the type which is then upon it is forced between a pair of yielding fingers 0, which project from the ends of guide-strips o2, properly arranged to receive the column of type T between them, as shown. in Fig. 3, said fingers o entering a space between the type-holding projections 'm3 on the carrier and bearing with suflicient friction to hold the type after the carrier has completed its movement, so that the carrier returns, leaving the type between the fingers 0, as shown in Fig. 3, the column being advanced as each new type is introduced by IIO the positive pressure of the carrier actuated as has been described. The carrying-arm for the platform m is in the shape of an elbowlever, as best shown in Fig. 7, and has pivoted upon it at m4 a stop m, which in the position shown in Figs. 1, 3, and 7 `operates to arrest the typeas they pass off from the main bed of the machine and onto the platform. The said stop is held in position to arrest the type by a spring m7, its movement under the action of the spring being limited by a `nger 'm8, which engages under the platform. The stop m8 supports the end of the type until the carrier arrives-at the position shown in dotted lines, Fig. 3,1and in full lines, y Fig. 5, when the said stop comes kin engagel ment with 4the framework below the receiv-` ing-lingers o, and in the further forward movement of the carrier to the dotted-line position, 6, by which the type is forced effectively into the grasp of the lingers o, thel said stop m is arrested and turns back on its l pivot m4 with relation to the carrier-arm, the l spring mq yielding to permit this movement 1 and the carrier-arm being recessed, as shown at m9, to receive the projecting end Vof the stop which extends over it, yas shown in Fig. 9. In the last part of the movement of the carrier the .fingers o enter recesses m10 (see Fig. 99 in the carrier, provided to accom-mo i date them. Astop w is provided to act on the type after they pass the lower cutters and before they are received upon the carrier m. The said stop is best shown in Figs. 8 and 9, and consists of a spring-fingerconnected with one of the pair of gui-des flo, between which the type are received from the lower pair of cutters e, said spring having its end work through an opening in the side of the said guide,ras shown in Figs. 9 and 3. The spring is operated by a lever w3, pivoted at w4 under the shank of the guide-piece f 10 and acted upon by a cam or projection w5 (see Figs. 8 and 9) at the side of the carrier m, these parts being so arranged that when the carrier comes to the full-line position, Fig. 3, so as to receive a type upon it, thecam w5 causes the stop w to be `pressed inward, so that if there are more than one type in the space below the cutters e the second type from the lcarrier will be engaged by the stop-linger and pressed against the opposite guide-piece suf- Iiciently to hold it while the lowermost type slides off from `the bed-plate B and onto the platform m. After the carrier begins its movement from the full to the dotted line position, Fig. 3, the cam w is removed from the end of the lever w3, permitting the stop-nger to spring outward and release the type engaged by it, which will then slide down until arrested by the guard or apron m5 in position to pass onto the carrier as soon as the latter comes back to its full-line position. The column of type, passing from the guide way o2, moves beneath a pressing-roll p, which may be covered with rubber or other yielding material, so as not to injure the face of the type which pass beneath it, but which holds said type `down to the action of the cutterpz, which cuts the usual groove in the .lower end of the type, which sprue after passing said sprue-cutter are com plete and may be delivered upon the receiving-stick T2. (See Fig. 2.) It is necessary to 'adjust the various parts that co-operate with the type in order tha-t they may act properly with type of 'd-ierent size. Itis, however, only necessary to adjust the cutters, feed-wheels, and side guides at one side of the path of the type. For convenience, however, both cutters of each pair are shown as supported in adjustable bearings. The cutter-shafts d3 land e3 are `supported in bearings d4 and e, properly constructed to prevent endwise movement orlooseness-of the shaft in the bearings, Whichlatter are mounted upon brackets or carriages d5 e5, adjustable on lateral1y-prejecting portions A4 from the inclined bed A2. Screws d@ e6 are provided for moving the bearing-braclrets on said supporting-arms, said brackets being slotted, as shown at dT e7 (see Fig. 2') to receive fastening-bolts, by which they are rigidly clamped when brought to the proper adjustment. The cutters at one side of the racew-ay 'are driven by aseparfate belt from those at the other side,asbest shown in Fig. 2, the several driving-belts beingmfai ntained in properstate Vof tension by idlers F, (see Fig. 1,) and the sprue-cutter p2 beingdriven by thesame belt that drives the cutters d e, as shown in Fig. 2. The said cutters are driven at a higher rate of speed than the feed-wheels, so as to have the proper action upon the type. The hold-down t', that co-operates with the upper pair of feed-wheels and upper pair of cutters, is extended and turned at its lower end, as shown at 117, Figs. 2 and 3,'to co-operate with the turning-guide 7c and assist in turning the type properly. The invention is not limited to the specific detailsof construction and arrangement hereinbefore described, as it is obvious that they may be varied widely without materially changing the essential features of construction and operation of the machine. I claim- 1.
