PUMP.

SPECIFICATION forming part of Letters Patent No. 334,211, dated January 12, 1886.

Application filed February 16, 1885. Serial No. 156,088.

To all whom it may concern:

Be it known that I, HIRAM M. D. L. BAB- COX, of San Francisco, San Francisco county, California, have invented a new and useful Improvement in Pumps, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of one of my improved pumps. Fig. 2 is a sectional plan view of the same, taken through the line :10 as, Fig. 1. Fig. 3 is a sectional plan view of the same,taken through the line y y, Fig. 1.

The object of my invention is to improve the construction of the pumps for which Letters Patent No.284, 708 were issued to me September 11, 1883, in such a manner as to make them more effective in operation and more easily operative.

The invention consists of the air-chamber with a lower open end combined with the plunger, the upper enlarged end of the pumpcase, and the enlarged upper air-chamber with a lower open end, and of the combination with the foregoing parts of the working-barrel with a surrounding water space or chamber, substantially as hereinafter more fully set forth and claimed.

A is the pump-case, the upper part, B, of which is enlarged, and is provided with a discharge-spout, O. The adjacent ends of the sections A B are flanged to receive the bolts that fasten them together.

\Vithin thelower part of the case Ais placed the working-barrel D, which is made smaller than the interior diameter of the said case A, so as to leave an annular space between the said barrel and case, as shown in Fig. 1.

Below the case A is placed the cylinder E, that carries an ordinary check-valve, F, and which is made of the same size as the pumpcase A. The valve-cylinder E is surrounded and protected by the case G, which is made larger than the pump-case A and valve-cylinder E,so as to leave an annular space between it and the said valve-cylinder, as shown in Fig. l.

The lower ends of the pump-case A and barrel D and the upper ends of the valve-cylinder E and valve-cylinder case G are flanged (No model.)

to receive the bolts that fasten the said four parts together.

Within the workingbarrel D is placed the plunger H, which is provided with an ordinary valve, I. The upper endof the plungerstem J is attached to the cross-bar K,secured to the open lower end of the air-chamber L. The air-chamber L can be a single chamber, or it can be made in two or more sections. In the latter case the closed upper end of each lower section is connected to a cross-bar, K, secured in the open lower end of the next upper section by a short rod, M, as illustrated in Fig. 1.

The closed upper end of the upper section of the air-chamber L is connected by a short rod, M, with a cross-bar, K, secured to the open lower end of the enlarged air-chamber L, placed in the enlarged upper part, B, of the pump-case.

To the closed upper end of the enlarged airchamber L is pivoted the lower end of a short pump-rod, N, the upper end of which is pivoted to the pump-lever O. The pump-lever O is pivoted at its forward end to a bracket, P, attached to the upper part of the enlarged upper section, B, of the pump-case.

\Vith this construction, as the free end of the lever O is forced downward the air-chambers are forced downward through the water in the pump-case, compressing the air in the said air-chambers, and the plunger is forced downward through the water in the workingbarrel, the check-valve preventing the said water from passing downward and the pressure of the water opening the plunger-valve, so that the plunger will readily move downward through the said water. As the downward pressure upon the free end of the pumplever ceases the compressed air in the airchambers expands,and part of the power thus developed raises the air-chambers, the plunger,and the water in the working-barrel above said plunger, and raises the lever for another stroke.

The balance of the power developed by the expansion of the compressed air forces the water out of the pump-case through the spout C.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a pump, the combination, with the pump-case having an enlarged upper end, of

the lower air-chamber connected to the plunger, and the enlarged air-chamber arranged in the enlargement at the upper end of the pumpcase, and having a lower open end, said air- 15 chambers being connected together, substantially as and for the purpose set forth.
