SPECIFICATION forming part of Letters Patent No. 394,256, dated December 11, 1888.

Application filed July 26, 1888. Serial No. 281,150. (No model.)

To coZZ whom it may concern:

Be it known that I, CORNELIUS (l. EPP, of Bradshaw, in the county of York and State of Nebraska, have in vented a new an d useful Improven'ient in Motors, of which the following is a specification.

My invention is an improvement in motors intended especially for operating pumps; and the invention cons in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure l. is a side view, and Fig. 2 a top plan view, of my improved motor. Fig. is a detail view of the swinging pawlcarrying arm. Fig. 4: is a detail view of part of the belt, and Fig. 5 a detail view of one of the pinions.

In carrying out my invention I provide a suitable framing formed in the construction shown of uprights A A A A A A A A and suitable cross-bars uniting such uprights and such other framing-bars as maybe necessary to support the several operating parts of my improvement. The drive -weight B is suspended 011 cord, chain, or rope B, which passes up over a guide-pulley, b, thence down, and is attached to a drum, B on a shaft, 0, on which shaft is fixed a ratchetwheel, C, and a gearwheel, C This gear-wheel C meshes witha pinion, D, on a shaft, D, which shaft also has a gear-wheel, D and a clutch-section, D actuated by spring (Z and which coacts with pinion D, the hub of which latter also forms a clutch-section to connect such pinion to the shaft when such pinion is turned in one direction, and yet permits the pinion to turn freely on the shaft in the opposite direction.

An arm, E, is supported to swing concentrically with the axis of shaft 0, and is usually pivoted on such shaft and depending therefrom, as shown, being connected at its lower end with one end of a pitman, E, the opposite end of which is connected with a crank-pin, E on a gear-wheel, E Such gear-wheel E is on a shaft, E, having a crank-handle, E and the gear-wheel E is meshed with a pinion, E, on a shaft, E, which shaft E also has a flywheel, E so motion given the shaft by the hand-crank may be rendered steadier and the operation be made easier, as will be understood.

By the described construction it will be seen that as the crank-shaft is turned the arm E will be oscillated. In order that the oscillations of the arm E may be caused to turn the shaft O, I support on such arm a pawl, 6, arranged to engage ratchet-wheel C and turn such wheel, and with it the shaft C, in such manner as to wind rope B on the drum 13*. This pawl is adjustable out of engagement with the ratchet-wheel, so that after the weight has been drawn up the pawl may be released from the ratchet-wheel, so that the turning of such ratchet-wheel as the motor is operating will not affect any operation of the swinging arm and the means for oscillating the same. In the construction shown the pawl is actuated by a spring plate, 0, hearing at one end against the pawl and pivoted near its opposite end, so it may be turned out clear of the pawl when it is desired to adjust said pawl out of engagement with the ratchet-wheel.

The shaft D is geared with a shaft, F, which is geared with a shaft, G, which in turn is geared with a shaft, H, the latter having a flywheel, I-I. The shaft G is provided with a wheel or pulley, I, and in a suitable supporting-frame in line with and preferably below the wheel I, I support the wheel or pulley I, a belt, J, being passed around said wheels I I.

By preference the wheels I I are sprocketwheels and the belt J a sprocket-belt, and the latter is provided at intervals with lateral projections .I, which on their downward motion engage one end of a lever, K, such lever being pivoted between its ends and connected at its opposite end to and reciprocating the pump or other rod, L, so the projections on the belt will operate to depress the inner end of the lever and lift its outer end and so elevate the rod L. To lift the inner end of the lever, I connect therewith a spring, M, which operates to lift the lever after it has been passed by the projections.

Ordinarily I make the beltJ with one hundred and twenty-six (126) links, and provide each twenty-first (21st) link with the projections, such projections being preferably extended on opposite sides of the belt, and the lever having arms fitting on both sides the belt in position for engagement by said projections.

011 the shaft G, I provide a weighted arm,

N, which bears such relation to the projections for operating the lever that the said arm descends as the projections engage the lever and rises after such engagement, thus assisting the belt in operating the lever.

The operation is simple, and will be fully-- understood from the foregoing description.-

The gear-wheel E may be provided, as shown in Fig. 5, with three holes to receive the crankpin, so such pin may be set nearer to or farther from the center.

Having thus described my invention, what I claim as new is 1. The combination, in a motor, substantially as described, of the weight, the drum, the connection between said drum and weight, a ratchet-wheel and pinion, the arm swinging on an axis concentric with that of the ratchetwheel and provided with a pawl arranged to engage said wheel, and a spring actuating said pawl and pivoted, whereby it may be set out of engagement with the pawl and the latter be adjusted out of engagement with the ratchet-wheel, the pitman connected with said arm, and means for operating said pitman, substantially as set forth.

vided on the shaft thereof with a weighted arm, a second pulley in line with said first pulley, a belt passing around said pulleys and provided at intervals with projections, and the pivoted lever arranged at one end for engagement by the said projections, all being arranged substantially as described, whereby as the projections on. the belt engage the lever the weighted arm will descend, as and for the purposes specified.

CORNELIUS C. EPP.
