IMPROVEMENT |N PUMP-GEAR Specification forming part of Letters Patent No. 43,387, dated July 5, 1864.

the same, reference being hadto the accompanyingdrawings, forming part of this specifica-tin', in which- Figure l exhibits a transverse section of the crankshaft and a side view of the pump-gear of a steam-en gine. Fig. 2 is aplan of the same, partly 'in section.

Similar letters of reference indicate like parts.

tion 'from the crankshaft of a steamlengine to a counter-shaft for working the feedpump, by means ot' a system of friction-wheels, one

of which is arranged as an idle-wheel, to be` thrown in and out of gear as required to connect 'the pump with and disconnect it from the engine, the object being to effect such eonuection and disconnection in a more easy manner than can be done by the means heretofore used and to relieve the engine o f all avoidable friction and the drivinggear of the pump of all avoidable wear when the pump is not in operation.

A is themain or crank shaft of the engine.

B is the' counter-shaft, arranged in suitable bearings, a a, and furnished'with a crank, G, for driving the pump.

E is a friction-wheel on the main shalt A,

and F is afrction-wheel onthc counter-shaft The peripheries of these wheels are made the wheels E and F. -This idle-wheelG hasl the journals of its shaft or axle H fitted to bearings in a forked` rod which is suspended from one end of a lever, I, which works on a fnlcrun1-pin, l), supported in astandard,J, and

the other end of which is formed into a handle, c. The said wheel G is arranged between the wheels E and F, below the centers thereof, an d is of' too large diameter for its center to come in line with the centers of E an'd F.. The portion of the lever near the handle c is received in a slotin a xed standard,K, in which there are twoholes, d and e, for the reception of a pin, j', which is inserted through one `of them and through a corresponding hole in the lever.

To connect the pumplwith the engine, it is only necessary to depress the handle far enough to bring the hole in the lever opposite to the lower hole, d, in the standard K, which brings the idle-wheel G into contact with the wheels E and F, and causes E to transmit motion through G to F, and so to drive the counter shaft and the pump. The pin f :is then'inscrted through the holes in the lever and standard K, and the Wheel Gr thereby kept in contact with E and F, and thepump kept v This invention consists in transmitting mo in operation.

When itis desired to disconnect the pump, it is only necessary'to talie out the pin f and raise the handle c of the leverhigh enough to permit the pin to be inserted through the upper hole, e, of the standard and the hole iu the 4ever, which keeps the idle-wheel G below the Y wheels E and F.

When the pump is connected, the frictionwheels transmit-the motion with the least possible'amount of friction, and when itjis discon#- nected the engine is relieved of all the friction of the pump-gear, so that there is neither waste of power nor unnecessary wear.

We claim as our invention and dlesire to sccure by Letters Patent- Y The employment, in combination with a counter-shaft, B, for driving the feed-pump of an engine, of a frictionwheel, E, on the main shaft of the engine, a friction-wheel, F, on the said counter-shaft, and 'an intermediate idle' l friction-wheel, G, suspend-ed from a lever, or

its equivalent, substantially las herein specified. Y
