MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 248,590, dated October 25, 1881.

Application filed March 8, 1881. (No model.)

To all whom it may concern Be it known that 1, Moses B. HARVEY, of the city of Leavenworth, county of Leavenworth, and State of Kansas, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a specification.

The objectof my said invention is to convert reciprocal into rotary motion, and is accomplished by passing the reciprocating bar between two wheels, loosely mounted on their respective shafts, between collars which are fixedly attached to said shafts, connecting said wheels and said collars by pawls or clutches which only engage when the respective wheels are moving in a forward direction, and fixedly mounting upon said shafts two other wheels connected by a belt, so that the rotation of one shaft shall always secure the rotation of the Other, all of which will hereinafter be more particularly described.

Referring to the accompanying drawings, which are made a part hereof, Figurel is a side elevation of an ordinary engine to which my mechanical movement is attached; Fig.2, a

. side elevation of the mechanical movement only from the other side; Fig. 3, a top or plan View of Fig. 1; Fig. 4, an end elevation of Fig. 2 as seen from the outer end; Fig. 5, a side elevation of the wheel B and a portion of the reciprocating bar which engages therewith, as seen in Fig. 1, except that they are on an enlarged scale and Fig. 6, a transverse vertical section on the dotted lines a: 00 in Figs. 1 and 2, except that it is on the same scale as Fig. 5.

In said drawings, the portions marked A represent the reciprocating bar or rod of my mechanical movement, which in this case is an extension of the piston-rod of a steam-engine; B B, the upper and lower wheels, respectively, with which the bar engages; O O, the shafts to saidwheels, D D, collars or flanges on said shafts alongside of said wheels; E E, clutches or pawls, which may be pivoted to either the wheels or the collars, and engage with the col lars, if pivoted to the wheels, or to the wheels, if pivoted to the collars; F F, pulleys on the shafts O G, and G a belt connecting them.

The reciprocating bar A and wheels B B may be either cogged, as shown, or smooth, in

the latter of which forms there must, of course, be suflicient pressure to cause them to operate by friction. I prefer the cogged form, except when there is to be but a light load orthe ma-' chine is to run at a high rate of speed.

The pawls or clutches E E are preferably duplicated on each wheel, as shown, to equalize the pressure on said wheels. They should also have springs e e to hold them up to their work. They can easily be reversed when it is desired to have the mechanism run in the opposite direction, or by means of a double set and some additional mechanism the reversing operation can be performed without changing the pawls further than to throw one set into engagement and the other out. The pulleysF F are, in lieu thereof, connected by a belt, as shown, so that the direction of rotation shall be the same with both.

The operation of my invention is as follows: When the wheels and pawls are constructed and attached as shown, the bar A, in moving from the engine or other operating power, causes the pawl on the wheel B to en gage therewithgand consequently rotates said wheel, its shaft, and the train of mechanism attached thereto, while the wheel B moves loosely around its shaft, its pawl slipping as it moves. When the bar A is moving toward the engine, however, the pawl on the wheel B engages 8o therewith, causing said wheel and its shaft to turn, while the wheel B slips loosely on its shaft.

By this means, and by means of the continuously-connected wheels F F, a continuous rotary movement in one direction is secured from the power furnished by the reciprocating bar.

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

1. The combination of the reciprocating bar 0 A, the wheels B B, the shafts G G, on which said wheels are loosely mounted, the flanges D D, fixedly secured to said shafts, the pawls or clutches E E, pivoted to said flanges and impingingon the rims of the wheels, the springs e e, for keeping said pawls in engagement, pulleys F F, and belt Gr, connecting them, when all constructed, arranged, and operating substantially as shown and described, and for the purposes specified.

2. The combination, with the loosely-n1ounted wheels of a device for converting recipro- In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 10 cal into rotary motion, the shafts thereto, and 23d day of February, A. D. 1881.

rigidly-affixed collars or flanges on said shafts, 5 ofpawls or clutches pivoted at one end to either the wheel or the collar, and adapted to engage with the other at the other end, all substantially as and for the purposes set forth. a

MOSES B. HARVEY.

In presence of-- O. BRADFORD, A. G. CHANDLEE.
