(No Model.) S. R. LEWIS. FEEDER LIFTER. No. 486,486. Patented .Nov. 22, 1892. I Inventor: UNITED STATES PATENT OFFICE. SAMUEL RILEY LEWIS, OF RATON, TERRITORY OF NEI/V MEXICO. FEEDER-LIFTER. SPECIFICATION forming part of Letters Patent No. 486,486, dated November 22, 1892. Application filed January 11,1892. Serial No. 417,778. (No model.) To all whom it may concern: Be it known that I, SAMUEL RILEY LEWIS, a citizen of the United States, residing at Raton, in the county of Colfax and the Territory of New Mexico, haveinvented a new and useful Feeder-Lifter, of which the following is a specification. My invention relates to improvements in the means for lifting the feeders of oil-cups on machinery; and the object of my improvement is to afford facilities for the extraction of the feeders from such oil-cups. I attain this object by the use of the instrument illustrated in the accompanying drawings. In the drawings, Figure 1 is a View of the feeder-lifter applied to and shown in connection with an oil-cup and feeder. Fig. 2 is a transverse sectional view of the jaws of the lifter. I The device is preferably made of steel and comprises two pivotally-connected members A A, provided, respectively, with jaws B B and having handles or reins C O. The jaws are interiorly chambered or concaved, as shown in Fig.2, whereby when closed an elliptical recess D is formed between the opposing concave surfaces thereof. One of the handles O terminates in a ring a and the other C terminates in a spiral coil or twist c, and the spiral spring E fits and engages the spiral coil or twist c and is provided with an arm E, which is notched at e to engage the handle O. The tendency of this spring, which is held in place by the spiral coil or twist, is to separate the jaws of the device. F represents the oil-cup, and a the feeder which projects therefrom. What I claim, and desire to secure by Letters Patent, is- A device of the class described, having pivotally-connected members provided with concaved jaws and handles, one of the handles terminating in a ring and the other terminating in a spiral coil or twist c, and the actuating-spring having a spirally-coiled portion which fits and engages the spiral coil or twist, and an arm which engages the opposite handle, substantially as specified.
