GEARED PUNlPlNG--ENGINE.I

SPECIFICATION forming part of Letters Patent No. 289,828, dated December 11, 1883. I

Application filed December 26, 1882.

To @ZZ wiz/0111, t may concern.-

Be it known that I, HARVEY F. GAsnILL, of Lockport, in Niagara county, New York, have invented certain v Improvements in Geared Pumping-Engines, of which the following is a specification.

My invention relates to geared pumpingengincs i'or water-works and other servicethat is, to pumps which are run at a different speed from the engine or other motor which drives them, the power being transmitted from the motor to the pump by gearing. The

object of such an arrangement is to reduce the frequency and amount of the shock which occurs at the change of stroke of the pump by giving the pump along stroke, and having it work at a low speed, while at the same time the motor may be run at a high speed, thus permitting the use of a small motor, with a consequent saving in iirst cost, and, in the case of a heat-engine, avoiding the cooling effect of large surfaces and low speed.

It is the object of my invention to produce a pumping-engine of the class named-viz., a geared pumping-engine-which shall be simple and compact, and thus save in rst cost, and occupy a small space, so as to be available for use in places where the space is limited.

Heretofore it has been common to use vertical engines in places where the floor-space was limited. By my invention I am enabled to use a horizontal engine in such places.

I accomplishv these several objects by constructing an engine substantially as follows, viz: Upon a suitable base I mount one or more pump-cylinders. Above the pump-cylinder I arrange a crank-shaft, revolving in bearings supported thereby, and on the crank-shaft is a gear-wheel. In front of the pump-cylinder are standards which support bearings for a beam. The beam oscillates in front of the pump, and has one end connected to the pumprod, and the other end connected to the crank. Strut-ties connect the standards with the cylinder and the crank-shaftbearing. In some cases the beam might be dispensed with, but I prefer to use it; and I prefer to use two pump-cylinders side by side, supporting the two ends of the crank-shaft, and having the gear-wheel between them, and two beams-one in front of each cylinder-and two cranks at an angle with each other on the crank-shaft.

(No model.)

In the claims at the end hereof I will specilically lpoint out the several portions of this structure which constitute my invention.

In the drawings I have represented a duplex machine of the kind named.

Figure l is a side view. Fig. 2 is a plan, and Fig. 3 is a detail, showing how the pumpplunger and the beam are connected, the beam being in horizontal section.

B are the pump-cylinders.

b is a pump-plunger.

Z is the valve-box of the pump.

f is a pillow-block or bearing `on the pump, which thus serves as astandard to support the pillow-block.

G is a crank-shaft, revolving on its journals in the bearings f.

F is a gear-wheel on the lshaft and between the two pump-cylinders.

O is the base-casting of the frame, resting on the foundations O Q. This base O extends back of the pump far enough to support a bearing for a shaft, I.

D is a pinion on the shaft I', meshing with gear F.

P are standards in front of the pumps, which support bearings for the beam-shaftj.

` Q and B. are strut-ties extending from the standards P to the pump-cylinders and to the cranl'r-shaft bearings, respectively, and forming a solid connection between the same.

J are beams, which oscillate on the beamshafts j.

g are ordinary connecting-rods or pitmen, which connect the upper ends of the beams with the cranks. The lower ends of the beams are connected to the pump-rods C by means of links c.

In practice, the shaft I may be the main shaft of the motor-engine, or it may be an aux iliary shaft connected thereto.

I have not thought it necessary to show the motor, as it would simply complicate the drawings, and any suitable form of motor may be used. f

In operation, the shaft I is made to revolve by some suitable steam-engine or other motor. This, through the pinion D/-and gear F, revolves the crank-shaft G, which, through its cranks and the connecting-rods, causes the beams to oscillate and aetuate the pumps. By placing the cranksat right angles, as shown,

IOO

. pump7 each pump will be at its point of greatest del livery when the other is changing stroke, and the resultant delivery will be more uniform in consequence.

TWhat I claim isl. The combination of the framing, the pulnp, the crank-shaft having a bearing on the pump, the main gea-r on the crank-shaft, and connecting devices between the crank and the pump-rod, substantially as described.

2. The combination of the framing, the the crank-shaft having a bearing on the pump, the beam, and the connecting devices constituting the Whole into an operative machine, substantially as described.

SELSQ@ 3. The combination of the framing, the pump, the crank-shaft having a bearing on the pump, devices forming an operative con-l nection of the crankshaft and pump, the gears F and D', the shaft I,and the backward eXtension of thebase toafford a bearing for the shaft l', substantially as described.

4. The framing composed of the base, the pump, the bearing f, the standard l?, and the strut-ties QR, substantially as described.
