OF SAME PLACE.

HAND-PUMP FIRE-ENGINE.

SPECIFICATION forming part of Letters Patent No. 375.317. dated December 20, 1887.

' Application medium@ 9,1857. serial N0.23o.251. (No model.)

To all wtom it may concern:

Be it known that l, A. DAYTON ELLIOTT, a cItIzen of the United States, and a resident of V1ola,in the county of Mercer and State of Illinois, have invented certain new and useful Improvements in HandPump Fire-Engines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which 1t appertains to make and use the same, reference being had to the accompanying drawings. and to letters or figures of reference marked thereon, which form a part of this specification. Figure l is a side elevation of my improved fire-engine. Fig. 2 is a transverse section on line x x, Fig. l: Fig. 3 is abroken transverse section taken through the pumps. Fig. 4 is a horizontal section on line y y, Fig. 3.

The invention relates to nre-engines; and it consists in the construction and novel combination 0f parts, as hereinafter set forth.

Referring to the drawings by letter, T designates the trucker carriage upon which the operative mechanism is mounted.

B is the horizontal suctiontube of the machine, and A is the force or delivery tube, to which the hose carrying the dischargepipe is attached. The delivery-tube is above and parallel to the suction-tube B.

P P designate the force-pumps, secured to the truck'l on each side and standing vertically therefrom, and p p are brace-rods, which secure the said pumps on the truck and prevent them from vibrating or moving laterally when the-truck is jarred, aswhen passing over a stone or when the water is being forced out of the tube A.

C C are air-chambers on the tube A, to regulate and make steady the outflow of water in the usual well-understood manner, and D is a priming vessel or chamber on said tube, communicating therewith only by the small tube d, provided with the cock b', so that when the said cock is opened water will be forced into and fill the priming-chamber when the machine is in operation.

The pumps P are all of identical construction, so that a description of one only is necessary.

5o Each pump P is composed of a cylinder, E,

having its lower end connected to and communicating with a water-chamber, K, the piston Q, and the piston-rod q, which has upon its u outer end a handle, q', of suitable construction, so that each pump can be operated independently of the others.

F is a water-pipe running around the machine, secured to the truck by proper supports, and receiving water from the priming-chamber D through atube, d', that connects the pipe F therewith. The pipe F communicates with each pump P preferably through a small tube, f, provided with a eock,f, so that water can be let into the tops of any one of the pumps by opening the corresponding cock, f. The pumps are thus primed from above when the machine is first put in action. The waterchamber K of each pump is situated at the lower end of. said pump, and communicates therewith through the opening R, having no valve. The said. chamber rises on the inner side of the lower end of the corresponding pump, and is provided below said pump with a diaphragm having the valve-seat r made in it, which seat is for the upwardly opening valve R. The water chamber has a diaphragm, O, in it above the'lowest point of descent of the piston, which diaphragm is provided with a valve-seat, o, upon which the upwardly-opening valve O' rests.

R is an opening in the vertical diaphragm of the water-chamber between the valves R and O and above the piston when it has descended to the lowest point of its stroke.

The chamber K communicates with the suction-tube B through the pipe S, which opens into said chamber below the valve R', and with the del ivery-tube A through the pipe S,which communicates with the chamber above the valve O. Thus when the piston descends water is forced up through the pipe S' into the delivery-tube A, and when. it ascends it draws water through the pipe Sintothewater-chamber K. When the piston is at its lowest point of descent, water lows above it, through the 9 opening X, from the chamber K, so as to moisten and pack it on the upstroke.

H is a waste-pipe running around the machine below and parallel to the pipe F, and each pump communicates with said pipe H IOO through a tube, h, which runs from the upper part of the cylinder of the pump to said pipe, so that when the piston is packed with water from above, as described, should there be more Water than necessary, the same will be lifted by the piston and discharged through the tube h into the pipe H, which is provided with a suitable vent-opening, h', as shown.

By means of the pumps attached to the truck any number of men equal to or less than the number of pumps can actuate themaohine, the men having to do Work in proportion to the decrease of their numbers.

By means of the construction of the Waterehamber K the piston is water-packed on its upstroke, and its rod does not need to Work through a stuffing-box.

The machine as described is conipact,handy, useful, and effective, and cannot easily get out of repair, as all the parts are of simple construction.

Having described my invention, I claim- The combination of thetruck, the receivingtube and delivery tube secured thereto by proper supports, the priming-chamber in the delivery tube and communicating therewith by the tube d, having the cock b, the pumps, the Water-vessels having the openings in their walls above the pistons when at their lowest point of descent, the pipe F, the tube f, provided with the cocks f', connecting the pipeE to the pumps, the discharge-pipe H, having the ventopening h', and the pipes h, connecting the said pipe and the upper ends of the pumpcylinders, substantially as specified.

In testimony whereof I afiix my'signature in presence of' two Witnesses.

A. DAYTON ELL lOTT.
