OF LOOUST VALLEY, NEW YORK, ASSIGNOR TOV OF SAME PLACE.

IMPROVEMENT IN CONVERTING ROTARY INTO RECIPROCATING MOTION.

Specification forming part of Letters Patent No.,0,90, dated July 20, 1858.

To all whom z't may concern.-

Be itknown that I, J. J. VEEKS, of Locust Valley, in the county of Queens and State of New York, have invented a new and useful Mechanical Movement Designed for Convert ing a Rotary into a Reciprocating Motion; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing, making a-part of this specification, said drawing being a side sectional elevation of my invention.

.Ihis'invention consists in forming an arm obliquely on a rotating shaft, and having acollar iitted loosely on said arm, the collar having a rod attached to itat right angles, and the lower end of the rod fitted loosely in an aperture in the slide or article to which a reciprocating movement is given from the shaft.

To enable those skilledu in the art to fully understand and construct niyinvention, I will proceed to describe it.

A represents' an upright, which is attached to a proper base, B, and G is a bearing on the upper end of said upright. D is ashzift, which is fitted in the bearing @,and E is an arm, which is formed on one end of shaft D, but obliquely with it, as shown clearly in the drawv ing. On the arm E a collar or hub, F, is placed loosely and secured thereon by a washer, G, and pin a. rIhe inner end of the collar or hub F bears' against a shoulder, b, the face of which is at right angles with the arm'. `To the collar orhub F a rod, H, is attached, and the lower end of this is tted loosely in a circular aperture, c, made in a slide 0r bar, I, which is fitted between proper guides, d.

From the above description of parts it will be seen that by rotating the shaft D the oblique arm E will so actuate the collar or hub By this invention an extremely simple and economical means is obtained for converting a rotary into a reciproeatinginotion, and there is another important advantage besides simplicity, to wit: rlhe position ofthe slide or bar I relatively with the shaft D is not arbitrary-n that is to say, the slide or bar may be shifted or moved obliquely with the shaft D without at all affecting the perfect operation of the device The device will prove highly valuable in those cases where a requisite space is not afforded for other means now employed for effecting the same result. For instance, in driving the reciprocating sickles of hart-*esters several wheels and a crank, or a combination of levers and a cam, have heretofore been` em ployedfor the purpose, and necessarily crowded into a small space, and thereby generally working imperfectly, besides adding greatly to the weight of the machine. By my imL provement this difficulty will be avoided.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is`

Forming the oblique arm E on the rotating shaft D, and placing the collar or hub F, with rod H attached, on said arm, the lower end of the rod H being fitted in the slide I, substantially as and for the purpose set forth.

JOHN J. WEEKS.
