THOMAS O. PERRY, OF TECUMSEH, ASSIGNOR OF ONE-HALF HIS RIGHT TO FRANKLIN W. DIOKEY, OF MARSHALL, MIOHIGAN.
IMPROVEMENT IN MECHANICAL MOVEMENTS V Specification forming part of Letters Patent No. 174,088, dated Eebruary 29, 1876; application tiled November 13, 1875.
To all "whom it may concern:
Be it known thatI, THOMAS O. PERRY,- of Tecumseh, in the county of Lenawee and State of Michigan, have invented certain Improvements in Mechanical Movements, of which the following is a specification The object of my invention is to obtain from a regular reciprocating or rotary motion a movement which shallbe reciprocating at intervals, controllable in either direction.
In the drawing, Figure 1 is a front view of my device. Fig. '2 is a side elevation, and Fig. 3 is a plan of the piece V.
S andS are ordinary sheaves. To S is attached a ratchet-wheel, W, both being loose on a pin supported at the upper end of the standard A. One end of the arm I is also loose on the pin, and to this arm is attached a ratchet, 1, which works into the ratchet-wheel W. The sheave S is attached to the piece T, which may slide up or down on the standard A, and acts as a weight to tighten the chain or cord (1, which passes around the sheaves S and S. To the standard A is bolted a block, I), through which passes a pin, 00, on which the piece V turns. V has two grooves, u u, so placed that the cord 0 runs in them on both sides. A knob, K, is attached to the cord 0.
Now, if a regular reciprocating movement be. given to the arm Z, the sheave S is made to rotate in one direction, imparting its motion to the cord 0, and when the knob K goes up on one-side, it turns the piece V in one direction, slips by, and when it comes down on the other side the piece V is turned back again. Thus a reciprocating movement is imparted to V at intervals, which may be'varied in duration by shortening or lengthening the chain or cord G.
It the piece V is placed. midway between the sheaves S and S, it will turn with equal intervals in either direction; but if V is placed nearer to one sheave thanto the other, the intervals will be unequal.
Without using a ratchet, rotary motion may be directly imparted to the sheave S with the same result.
I claim as my invention- 1. The reciprocating piece V, constructed as shown and described, in combination with the sheaves S S, cord O, and knob K, as and r for the purpose herein set forth.
2. The piece V. in combination with the reciprocatin g arm l, ratchet r, ratchet-wheel W,
sheaves S S, cord 0, and knob K, to operate 7 substantially as and for the purpose shown and described.
THOMAS O. PERRY.
