Patented Aug. 4, 190s. l,

Application filed July 16,1907. serial No. 383,982.

To all whom it may concern:

Be it known that I, WILLIAM SULLIVAN, a citizen of the United States, and aresidentof Hot Springs, in the countyof Garland and State of Arkansas, have invented anew and Improved Mechanical Movement, of which l the following is a full, clear, and exact description.

The object of the'invention is to provide a new and improved mechanical movement.

for converting reciprocating motion into a rotary motion ina very simple and eective manner.

The invention consists ofk novel features and parts and combinations of ,the` same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all vthe views.

Figure 1 is a side elevation' of the improve'` ment; Fig. 2 is a plan view .of the same, `and Fig. 3 is a transverse section of the same on the line 3-8 of Fig. 1.

On a suitably constructed frame A, is`

mounted to reciprocate the cross head B, provided at its ends with handles B, adapted to be taken hold of by the operator for imarting a reciprocating motion to the cross ead B. On the cross head B are mounted v to swing two setsof pawls D and C', adapted to engage a ratchet wheel D, at diametrically opposite points, each set of pawls C, C being arranged in a longitudinal row so as to suc-` cessively engage and turnthe ratchet wheel D. The pawls as shown are each formed'of parallel and spaced rods or bars connected at their ends by plates. The ratchet wheel D is secured on a shaft E, journaled in suitable bearings mounted on the main frame A, and on the said shaft E is secured a pulley F, for transmitting the rotary motion of the devic to other machinery to `be driven.

Each of the pawls C has a limited swinging l motion on the cross head B, and for this purpose each pawlextends through elongated slots B2, Jformed in the sides of the cross head B. The sets of pawls C, C are respectively pressed on by springs G, G 4to hold the pawls in proper relation relative to the teeth of the ratchet wheel D, to turn the latter on reci rocating the cross head B. `Now when t e cross head B is caused to slide in the direction of the arrow 0/ ,then the upper the successive teeth of successivelyenga e the ratchet wheeld), to turn the latter in the direction of the arrow b. When the cross head B has reached the end of its stroke itis caused to slide backward, that is, in the inverse `direction of the arrow a', and in doing so the pawls C become active, that is successively en age successive teeth of the ratchet whee D to Jfurther rotate the ratchet wheel in the direction of the arrow t. During the forward sliding of the crosshead B in the direction of the arrow a/, the pawls C are active, as above described, while the pawls C glide over the teeth of the ratchet wheel D, an when the cross head B is on the return stroke in the inverse direction of the arrow a', then the awls C are active, as above mentioned, w ile the awls C glide over the teeth of the ratchet wieel D. Thus by the arrangement described a continuous rotary motion is given to the ratchet wheel D, the shaftV E and the pulley F, on reciprocating the cross head B, as above explained.

The mechanical movement shown and described is very sim le and durable in construction, compose of comparatively few parts, and not liable easily to get out of order.

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

1. A mechanical movement comprising a Jframe, a ratchet wheel mounted in the frame, a cross head mounted to reciprocate in the frame and having oppositely arran edf pairs `of s aced members provided with s ots, and a p urality of pawls pivoted to each pair of members of the cross head and adapted to engage the ratchet wheel at diametrically opposite points, each awl consisting of spaced rods connected y plates, one rod forming the pivot and the other the pawl proper and working in the slots of the mem' ers of the cross head, and springs for holding the pawls `in proper position.

2*. A mechanical movement comprising a frame, a ratchet wheel mounted inthe frame, ay cross head mounted to reciprocate in the frame and having oppositely arranged pairs `of spaced members each provided with transverse slots, and a lura ity of pivoted and lspring pressed paw s carried by each pair of pawls C Y 3. A mechanical niovenient7 comprising a I slots7 and springs on the cross head ratchet Wheel, mounted to turn, a reciprocatl pressing the said pawls.

impart a continuous rotary motion to the UAM SUlililYAN. Wheel, the said paWls being pivoted to the l Titnessesz cross head adjacent to the slots and having A. C. POLK,

their free ends extending through the said J. P. MELLARD.
