IMPROVEMENT IN COMBlNATiON PUMPS` AND FIRE-ENGINES.

Specification forming part of Letters Patent No. 175.502, dated March 28, 1876; applioai n filed v February 3, 1576.

' FireEngines; and do hereby declare that the following` is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part 4of this specification.

The nature of my invention consists in the construction and arrangement of a doubleacting force-pum p, which is applicable to and useful for all varieties of steam-engines, tireengines, bored and deep wells, shallow wells, and cisterns, and for any place where a pump can be used, as will be hereinafter more fully set forth.

In the annexed drawing, Figure 1 is a side elevation' of my pump. Fig. 2 is a longitudinal section of the same. Figs. 3 and 4 show detached parts thereof.

A represents the cylinder, provided with the heads B B', having anges screwed onto the ends of the cylinder, and fastened by screws a' rlhe ,upper head B has two openings, b b, and the lower head B has only one opening, b', and each opening has a cross-bar, a, to prevent the valves from springing or bending. On the inside of each head is' 'a shallow recess, d, into which the valve falls, and remains secure from walobling; C C are the upper and lower valves, respectively. D is the plunger, with exterior packing-groove e. This plunger is made in two parts, and forms an interior box, in which the sheet-m etal valve h is placed, said valve having a roundhole in the center, and used for double action. The plunger is concaved on top and bottom from the edge nearly to the center. The upper side is almost entirely open, with four cross-bars, and

in the center it has a hub, into which the ejector-pipe E is screwed, said pipe extending through the upper head into the lirst section of the exit-pipe F, attached to a hub on the upper head. G represents a coupling, used for extending'the tube F, which connects with the combined air-chamber and reservoirH H. I is an offset, that connects with the second section L of the exit-pipe, at the upper end of which is another air-chamber, M. N' shows the connection ofthe spout O'to the chamber,l

side of the reservoir H', and through a small tube, k, that is screwed into the upper end of the air-chamber H, said tube extendingdown to the reservoir, as shown in Fig. 2, the rod It passing through the shifting-box K upward along Jthe line of the exit-pipe I1. The upper end of the rod R is, by a coupling, T, connected to a short piston-rod, V, a pin, z', passing through said coupling, to connect the lower ends ofthe stirrups m m to it, the upper ends of said stirrups being fastened to the jaws of the short lever or walking-beam` W. The other end of this short lever is fastened to the long lever W by means of a bolt, n, which passes through the jaws at that end ot' the short lever, and through an elongated slot made in the long lever, said bolt also passing through a roller, p, in the slot, which relieves the friction. The long lever W is pivoted to the fulcrum at X. This arrangement ot' levers gives a powerful compound leverage.

When the cylinder-heads are not screwed on,rods may be used to fastenthem, as shown.

To prevent my pump from freezing, a short pin,1 ,is passed through the piston-rod a short distance below the reservoir, the plunger being down, so that when the outer end of the lever is down the check-valve f in the reservoir is raised, and thedwater in the pipe in1- mediately falls back into the well or cistern.

To make this pump very cheap, I will connect the exit-pipe with the upper head one side of the center, and the ejector-pipe a corresponding distance from the center of the plunger, and provide a suitable stufng-box PATENT Gr-TICEo C' closes, and the water below'tlre plunger forces (lie val ve h in the plunger upward, thereby allowing snidwater to pass out through the ejector-pipe E, and so on. When the plunv ger thus ascends again the water above the plunger forces the valve It downand this Wa.-

, ter passes out througlrtlie ejector-pipe. By

removing the vulve li, and placing a suitable vulve on the plunger, it will Vform a ysingle-acting pump. x

For the purposes ot re engines, two of these pumps are used, the exit-pipe sections:

L being tlzen connected to the same, (enlarged,)

,nir-chamber M having one or more nipples for the attachment ot' hose, and the levers bein gcsuitably arranged for operation.

Having thus fullyK described my invention,

'what I claim as new, and desire to secure by 1. A head for apump-cylinder, formed with an interior` recess, d, and provided with a valve-supporting bar, a, t'or the purposes herein set forth.

2. The combination of the cylinder A,`p.l`un ger-1),'ejectorepipe E, piston-rod R, exit-pipe F, and the combined air-chamber-and reservoir H H', all as shown and described.

3. The check-valve f, arranged in the bottom [of -tllereservoir H', as shown. and described.

4. The combination, in a pump, ot' the combined reservoir ,and air-chamber H H', exitpizpe L, air-chamber M, spout O, and stop-cock P, as shown and described.

5. The combination, with the piston-rod R and stirrups m m, of the short lever'W, the

long slotted lever W', bolt n, and roller p, al1

as and for the purposes herein set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two Witnesses. i
