SPECIFICATION forming part of Letters Patent NO. 461,215, dated October 13, 1891. Application filed August 21, 1890. Serial No. 382,603. (No model.) To all whom it may concern: ably to provide bearings for the holders, Be it known that I, CARL J. CARLSTROM, a which slide on the guideways during the subject of the King of Sweden, residing at movements of the tool-holder, there being Jamestown, Chautauqua county, and State of sufficient friction between the bearings and 5 New York, have invented certain new and the guideways to steady the holder in its useful Improvements in Carving-Machines, of movement. These tool-holders 11 are adapted which the following is such a full, clear, and to be reciprocated on their bearings over a exact description as will enable any one skilled range of movement as great as may be necin the art to which it appertains, to' make and essaryfor instance, a range equal to the IO use the same, reference being had to the drawwidth of the work-table-the reciprocating 6o ings forming part of this specification. movement being imparted thereto by means My invention relates to a machine for carvof a pattern-belt hereinafter described. ing upon wood or other material designs in Each tool-holder llis provided, preferably relief or intaglio. near the end thereof remote from the end car- 15 The object of the invention is to provide rying the tool, with a supporting wheel. or an automatically-operating machine for raproller 18, which travels back and forth on a idly turning out the work; and to this end the track 19, arranged horizontally in the mainvention consists in the certain novel and chine-frame'lO. This supporting-wheel 18 is peculiar arrangements and combinations of preferably placed upon one side of the holder, 20 parts, all as hereinafter fully described, and and upon the other side thereof are mounted then pointed out in the claims. belt-pulleys 20 and 21, over which passes the In the accompanying drawings, in which spindle-driving belt 22, which drives the pullike figures of reference designate like parts ley 14 of the toolspindle 13, and 'thus' the throughout, I have illustrated an embodicarving-1300112.

Figs. to by means of the pattern-belt hereinafter 5 and 6 are detached views of the patternto be described. Thus each tool-holder 11 may belt and a portion of a pattern-rack, thejoint be rocked or vibrated in its plane of recipro- 5 use of which in the machine will outline the cation on an. axis normal to such plane. The figure shown in Fig. 7,,as will be fully herebelt-pulley 20 of each ofthe tool-holders is i ft ib t preferably located to the side of the rocking Referring to the drawings, 10 designates center thereof opposite that upon which the the machine-framing, which is made of asuitcarving-tool is located, so that the tension on 40 able form to contain the operative parts of the the spindledriving belt 22 may tend to coun- 0 machine. In the upper part of the framing terbalance the weight of the opposite end of are mounted a set of reciprocating and rockthe tool-carrier. The belts 22 after leaving ing tool-holders 11, which carry the carvingthe drive-pulleys 23 are crossed, one side pass tools 12, driven by spindles 13, which are proing over the pulley 20 and the other over the 5 vided with pulleys 14. The tool-holders 11 pulley 21,and thence to the spindle-pulley 14, are each arranged, preferably, vertically and so that as the tool-holders are moved toward are provided with guideways 15, supported the rear of the machine and are brought more by the hangers 16, which depend from the directly over the drive-pulleys 23, which are upper part of the machine-framing 10. The located to the rear of the machine, the stretch 5o sides 17 of the tool-holders are formed suitof beltbetween pulleys 23 and 20 will lengthen, Ioo while that between pulleys 23 and 21 will shorten, thereby compensating and keeping the tension on the belt uniform. Each tool-hold er 11 is provided with an arm 26, extending from near the rocking center thereof to slightly beyond the end of the toolholder carrying the tool and forming a wide fork therewith, so as to embrace with ample clearance the work-table 61, the said arm 26 extending below the work-table and being provided with a guide 28, mounted adjustably thereon by means of set-screw 29, and which engages with the traveling pattern-belt 31. The guides 28 are form ed with a central opening 32 for receiving the arm 26 of the toolholder and are provided with fiat side bearings 33, which slide on the guide-bars 34, fixed in the machine-framing in suitable po-' sitions. These guide-bars 34 are preferably extensions of the tracks 19, upon which the supporting-wheels 18 of the tool holders travel. The reciprocatory and rocking movements of the tool-holders 11 are controlled by the patterns of the pattern-belt 31, which consist in the present construction, ofv suitable sections 35, hinged together by links 35, and constituting an endless sectional belt, which is mounted upon the drums 37 and 38, the latter of which effects the driving of the belt through means of shaft 39, gears 40 41, shaft 42, pinion 43, fixed upon the latter, gear 44, pulley 45, the gear 44 and pulley 45 being keyed upon a sleeve 46, turning loosely on shaft 39. The pulley 45 receives its motion through means of the band 47, which f passes over guide-pulleys 48 and 49 on shaft 50 and which receives its motion from the main shaft 24 through means of pulley 51, shaft 52, band-wheel 53, belt 54, and pulley 55, fixed upon said main shaft. The patterns of the belt are composed of sections or plates 56, which-are removably secured to the beltsections 35 by means of fasteners or screws 57 and are provided with the pattern ribs or grooves 58,runninglongitudinallyof theplates and shaped after a predetermined design. The pattern rib or groove 58 is engaged by the guide 28 of each of the tool-holders. In thecase where the part 58 is a rib or projection the end of the guide 28 engaging the same is notched or forked, as at 59, to receive such rib or projection, which serves to move the guide 28 back and forth transversely of the pattern-belt, and thereby reciprocate the tool-holder and the tool carried thereby crosswise the Work 60, which is clamped upon the work-table 61. The rockingor vertical move-. ment of the tool-holder is imparted thereto by means of the pattern element 58 of the belt in accordance with the elevations or depressions of the same, as will be understood from the side view of the pattern-belt, as shown in Fig. 1. The pattern-belt therefore controls the extent of movement of the carving-tools made greater or less than that of the guide controlling said tool, since such a variation of position will vary the distance of the guide from the. center of the rocking motion of the tool-holder. The design of the pattern of each section thereof may be alike, or the design formed by every two or more sections together may be alike. There may be as many sets of the pattern-sections running side by side as there are tools to be controlled, in which case each set of pattern-sections would be engaged by. but one guide 28, which, instead of then being in a straight line longitudinal of th pattern-belt, would be disposed one in advance of the otherthat is to say, to a person standing in -front of the machine, the carving-tool controlled by the guide which engages the set of pattern-sections 56 near the front of the machine would be nearer to the observer than a carving-tool the guide of which engaged with pattern-sections nearer to the rear of the machine. By virtue of having the tool-holders so constructed that they may be controlled by different sets of the pattern-sections the carving-tools carried by the holders may be positioned so as not to be in the same vertical plane, and hence the cutting done byone tool is not worked. over by an adjacent tool when the reciprocating work-table 61 is madeto traverse a greater distance than the distance between the two adjacent tools. The upper portion of the pattern-belt is supported and maintained in perfect horizontal position by means of the bed 112, as will be understood from Fig. 1. The Work-table 61 is mounted horizontally upon the ways 62, and is reciprocated on its lengththat is, in the direction of the motion of the pattern-beltand is controlled in its movements by my novel form of patternrack 63. The work-table is provided with the fixed dogs 164 at one side thereof and with a clamp 165 at the opposite side thereof, by means of which dog and clamp the board 60, upon which the tools are to carve, may be held firmly in position. The pattern-rack 63 is formed after a predetermined design, the design depending upon the design that'is to be carved. The pattern-rack 63 is mounted so that it maybe reciprocated lengthwise, and to that end it is provided with a suitable guide-frame 64, which slides in the ways 65, secured to the machine-framing,and is detachably connected with the work-table 61 through means of the bracket 66 and the gravity latch or arm 67, IIO :that is to be carved. teeth and forms an endless or closed rack, which runs straight in parts, then curved or serpentine, as may be required by the'design The rack is fed or operated by'means of a gear 71,n1ounted on an arbor 72, which is provided with a pinion 73, gearing with a bevel-pinion 74, which is driven by the shaft 75. - directly by the shaft 39 of the pattern-belt Y drum 38 through means of the bevel-gears 76 back of the frame 87. and 77, shaft 78, pinions 79 80, shaft 81, and cog-wheels 82 and 83, the latter being keyed upon shaft 39, the peculiar arrangement of the gearing between the shafts 75 and 39 being rendered necessary on account of the range of movement of the pattern-rack 63, which by such arrangement is allowed to pass between the gears 79 S0 and 82 83. The shaft 75, which feeds the pattern-rack, is formed with a joint 8l,which in the present construction isin effectauniversaljoint. Theendoftheshaft75, upon which is fixed the pinion 76, is mounted in a fixed bearing 85, while the other end thereof is'mounted in a bearing 86, that is secured to a swinging frame 87. The frame 87 is mounted so as to swing in a plane parallel to the pattern-rack by means of a base-plate 88, formed with an annular groove 89, in which projects a tongue 90, formed upon the The arbor 72 is mounted upon the end of the swinging frame 87, and the joint in the shaft 75 has the same center of motion as the swinging frame 87, so that the end frame 87 and the shaft 75, mounted thereon, may be swung up or down while the shaft is running. The gear 71, which drives the pattern-rack, is held in engagement with the teeth of the rack by means of a groove or slot 91, which runs parallel with the rack throughout and into which projects one end of the arbor 72, upon which the gear 71 is mounted. It will now be understood that the rotation of the gear 71 will feed the rack in one direction or the other, according to the direction of rotation of the gear, when running on the horizontal or curved poztions of the rack, but that it will not effect any movement of the rack when running on the vertical portions thereof. In this way the back-and-forth movements,as well as the periods of rest, of the work-table are under complete control of the pattern-rack. In the foregoing description it will be seen that the design to be carved by my machine is controlled by the combined action of the two component pattern mechanisms, one being the pattern-belt which controls the toolholders carrying the cutters and the other being the pattern-rack controlling the move- The shaft 75 is driven in-- ments of the reciprocating work-table. The joint effect of the simultaneous operation of the two pattern mechanisms above alluded to will be readily understood upon referring to Figs. 5, 6, and 7, wherein 31 is a form of pattern-belt in which the sect-ions of the patternbelt are formed with pattern-grooves 58, which run either straight or obliquely across the sections and form acontinuous element running longitudinally of the belt. Fig. 6 shows a portion of a pattern-rack which when used in conjunction with the pattern of the belt shown in Fig. 5 will cause the outline shown in Fig. 7 to be carved. Supposing the feed-wheel 71 of. the pattern-rack to be at point a in Fig. 6 and moving in the direction of the adjacent arrow and that the patternbelt is passing under the guide 28 of one of the tool-holders at a point a in Fig. 5 and in the direction of the arrow, by the time the feed-gear 71 has fed the pattern-rack from a to b, Fig. 6, the pattern-belt will have passed under the guide 28 from a to b, Fig. 5, and the combined action of these pattern devices will cause the carving-tool to cut the line from a, to b in Fig. 7. At this point there is a turn in the pattern-rack from b to b, and as this is almost a dead-point in the work the patttern of the belt is so constructed from b to b that the carvingtool is raised out of action. As the patternrack is fed from b to c, Fig. 6, the patternbelt is moved from b to c, which resultant action causes the line to be cut on the work from b to c, Fig. 7. As the pattern-rack is fed from c to c the belt moves from c to c,- and conjointly they produce the sharp turn 0 in the work. As the pattern-rack is moved from c to d the pattern-belt is simultaneously moved from c to d, and the joint action produces on the work the cut from c to d. The turn from dto d in the pattern-rack, combined with the stretch from d to d in the pattern-belt, produce together another sharp angle in the work at d. The simultaneous movement of the pattern-rack from d to e and of the pattern-belt from d to Q will jointly result in the cutting of the line from d to e on the work. The turn from c to e in the pattern-rack and thestret'ch from 6 to e in the traveling belt conjointly produce the angular turn 6 in the work, and then the movement of the rack from c tof and of the belt from c to f serve to cut the line from c tof on the work. (See Fig. 7.) In this way by the simultaneous action of certain parts of the pattern-rack and pattern-belt, the relations of which are prearranged in accordance with the design to be produced, the design is finally carved by the joint action of the two component'patterns. The lines 000: (shown in Fig. 7) are carved simultaneously by different spindles, the work having to be put am enabled to carve a great variety of work. Moreover, different patterns may be readily substituted and the work rapidly turned out. I desire to be understood as not limiting myself to the precise form of constructions of the pattern-belt and pattern-rack and the reciprocating and rocking tool-holders herein shown or described or the particular form of the feeding mechanism for the pattern-rack, since these features, considered together or separately, are broadly new, as well as several other minor features which are particularly pointed out in the claims. It will be observed that the depth to which a carving-tool may cut will depend upon theheight of the rib 58 of the pattern when a rib is used or the depth of the pattern-groove when the groove is used. In the carved figure shown in Fig. 7 the points b d are repre: sented in the pattern-belt in Fig. 5 by the lengths of the pattern-groove 58 between the 1 points I) b d d, the groove at this point berack, and therefore when the table is again to be connected to the p-atterrrrack another one of the notches 70 of the bracket will be brought into use, and for this reason there are to be a setof notches 70 in the bracket 66.
