To all t0/0m t may concern:

Be it known that I, HARRY P. PFLUM, a citizen of the United States, and resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful mprovements in Mechanical Motors, of which the following is a specilication.

This invention relates to mechanical motors and more especially to the hand operated type of such machines and consists of a novel arrangement of levers carrying a gear wheel and pawl, the latter adapted to engage the teeth of the gear wheel and hold it rigid while meshing with a pinion on the motor shaft, as will be more fully explained in the following specification, set forth in the claims and illustrated in the drawings, wherein,-

Figure 1 is a side elevation of the motor with its operating lever thrown down. Fig. 2 is a similar view with the lever elevated. Fig. 3 is a view from the4 opposite side of the motor. Fig. 4t is an end view. F ig. 5 is a detail view.

The motor may be attached to any machine that is necessary to be driven, and it is operated manually by means of a lever 5 pivoted within a frame or uprights 6. The motor shaft 7 is journaled in each side of the frame 6 and has secured to it the fly wheel 8, while at its other end it may carry any desired form of shaft or motive pulley. This shaft has also secured to it a pinion 9 by which it is given motion through the gearing and levers connected with the lever 5 and clearly shown in the drawings.

At each side of the pivot 10 of the handle 5 are links 11 and 12 pivoted to the handle and carrying at their outer end, arms 13, spacing the two links 11 and 12 at substantially the same distance throughout their length. The rivet 14: which connects the links 11 and arms 13 also forms the bearing for a pawl 15, adapted to be shifted thereon so as to cause one or the other of its ends to engage the teeth of a gear wheel 16, journaled on the pivot 17 which connects the links 12 with the arms 13. This pivot 17 also connects with these above mentioned parts levers 18, whose other end swings freely on the shaft 7. As will be seen in Fig. 4, there are two sets of levers 18 and also of links 11, l2 and the arms 13, eachset arranged on different sides of the pinion 9,gear wheel 16 and pawl 15.

The pawl 15 is shifted so as to engage the teeth of the gear wheel 16 from either side m order to rotate the wheels in the desired direction, Figs. 1 and 3 showing` the pawl engaging on the up stroke of the handle and the shifting being accomplished by means of the rods 19 and 20, connected by means of the bell crank lever 21 and operated by a small lever 22 carried at the outer end of the handle 5.

As the handle 5 is stroke will cause the pawl 15 to slide over the teeth of the gear wheel 16, while the pivot 17 of this wheel is being carried upward by the link 12. rlhe wheel 16 travels loosely around the pinion 9 or moves with it if the iiy wheel is in motion, but upon the upward movement of the handle 5, the pawl engages the teeth of the wheel 16, while the link 12 throws its pivot 17 downward, causing the handle 5 to exert its power upon the teeth or periphery of the wheel which mesh with the teeth of the pinion to drive the fly wheel in the direction shown by the arrow. The movements of the links l1 and 12 are always in opposite direction on 4account of their being connected with the handle at different sides of its pivot and the movement of arms 13 which carry the pawl is always a swinging movement around the wheel 16. When it is desired to reverse the direction of the wheel 8, the pawl is shifted hy means of the lever 22 and caused to engage the teeth at its opposite end.

It is obvious that the parts may be otherwise arranged or modified without departing from the essential features above shown.

Instead of using manual force to operate the' handle of this improved motor, steam, electrical or other powers may be employed to oscillate it and operate the motor so as to produce the desired result. By increasing the length of the handle greater leverage may be secured and more power produced.

What I claim as new and desire to secure by Letters Patent is,-

1. In a mechanical frame, of a motor, the combination with a motor shaft journaled in the frame, a pinion on the shaft, swinging arms on the shaft, a gear wheel at the ends of the arms, a handle, links connecting one end of the handle with the arms, additional operated, the down arms carried by the shaft of the gear Wheel, links connecting 'the latter arms with the other end of the handle, anda paWl at the junction of the additional arms and the second set of links.

2. In a mechanical motor, the combination with a shaft and pinion, of a frame carrying same, levers journaled on the shaft, a gear Wheel carried by the outer ends of the levers and meshing with the pinion, a handle pivoted near its end, links at one end of the handle and `connected with the ends of the levers, swinging arms carried at the ends of the levers, a pawl carried by the arms and links Vconnecting the arms and paWl With the other end of the handle.

3. In a mechanical motor, the combination With a fra-me, of a shaft and pinion,

levers swinging on the shaft, a gear wheel journaled at the outer end of the levers, a handle fulerumed at the upper end of the frame, links at the outer end of the handle and connected with the levers, arms at the outer ends of the levers, a pavvl carried by the arms and adapted to engage the teeth of the gear Wheel from either end, links connecting the levers and the pawl with the inner end of the handle, and a lever and rods adapted to shift the paWl.

Signed at New York in the county of New York and State of New7 York this 11th day of November A. D. 1911.
