IMPROVEMENT IN MECHANICAL MOVEMENTS.

DivisionY B.

To all whom t may concern: .l

Be it known that we, JOHN L. GOLES and DAviD H. CoLEs, both or the city, county, and State of New York, have invented a new and useful Improvement in Mechanism for Changing Motion 5 and we do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which drawing- Figure l represents a sectional side elevation ot' this invention; Fig. 2 is a horizontal section thereof; and Fig. Bis a plan or top -view of the same.

Similar letters indicate corresponding parts.

This invention consists in the combination of a cam-slide with a bar or lever that is free to oscillate, and also to slide on its i'ulcrum, said cam-slide being feathered on an arbor u hich can be revolved in such a lnanner that by imparting a reciprocating motion to the cam-slide an oscilla-ting or reciprocating motion is given to the bar or lever, and that by turning' the arbor ot' the cam slide the motion ot' thebar or lever can be changed at any moment, and that by connecting said bar or lever to dili'erent mechanisms various ettects can beproduced. An adjusting-screw serves to regulate the throw of the cam-slide and the amount of motion imparted to the bar or lever.

In the drawing, the letter A designates a bar or lever, which is provided with a slot, a., through which passes a screw, b, which screws into the table B, or in any fixed part of a machine, so that said bar is free to oscillate or to assume a reciprocating` motion on its ful-- crum-pin b. The rear end of' the bar or lever A forms a ring.r or eye, c, which embraces the cam-slide G. This slide consists ot' a cylinder placed in an oblique position on the rod I), and it is subjected to the action of a cam, E, and of a. spring, F, which spring has a tendency to press the cam-slide toward the face ot' the cam. by the combined action of the cam and spring the canrslide receives a rcciprocating motion through the eye ot the bar or lever A, compelhng said bar to assume a reciprocating or an oscillating motion corresponding to the Obliquity of the cam-slide. By a screw, G, the cam-slide can be set closer to or further from the. cam E, and thereby the throw ot' the cam-slide, and consequently the amount otl motion imparted to the bar or lever A, is changed. On the rod D, which forms the guide ot' the cam-slide, is mounted a cogwheel, H, which gears into another cog-wheel I, mounted on an arbor, J, which projects up through the table B, and to the upper end of which is secured a handle, K, which sweeps over a dial-plate -inserted into or marked on the table. By turning this handle the rod D and also the cam slide are turned, and the motion ofthe bar or lever A is changed, the handle being adjustedrin such a manner that it indicates the direction in which the bar or lever A moves. The bar or lever A connects with the feed-dog of a sewing-machine, or with any other mechanism the motion ot' which is to be changed, and a simple and compact device is thereby produced for efi'ecting manifold changes in the mot-ion ot' those parts to which said bar or lever Inay be attached.

/Vhat we claim as new, and desire to secure by Letters Patent, is

1'. The combination of a cam-slide with a bar or lever that is free to oscillate and also to slide on its fulcrnm, said cam-slide being feathered o n an arbor which can be revolved, substantially as and for the purpose herein shown and described.

2. The combination of an adjusting-screw with a cam-slide which is feathered on au Iarbor that can be. revolved, and with a bar or lever that is free to oscillate and also to slide on its fulcrnm, substantially as and for Athe purpose set forth.

3. A bar or lever which is free to oscillate and also to slide on its fulcrum, in combination with a cam-slide and with mechanism for turning the same, substantially in the manner Vand for the purpose described.
