DOUBLE-ACTING PUMP.

SPECIFICATION forming part of Letters Patent No. 432,373, dated July 15, 1890.

Application filed March '7, 1890. Serial No. 342,980. (No model.)

To all whom it may concern:

Be it known that I,- JOSEPH M. CLARK, of Colfax, in the county of Whitman and State of Washington, have invented a new and Improved Double-Acting Pump, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved pump which is simple and durable in construction, very elfective, and double-acting in operation, and not liable to get out'of order easily.

The invention consists of certain parts and details and combinations of the same, as will be hereinafter fully described, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a 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 the improvement. Fig. 2 is a sectional plan view of the same on the line as so of Fig. 1. Fig. 3 is a like view of the same on the line ug of Fig. 1. Fig. 4 is a transverse section of part of the improvement on the line '2 z of Fig. 1, and Fig. 5 is a sectional side elevation of the device for letting out the water to prevent freezing.

The improved pump A is provided with a U-shaped barrel 13, preferably made in three parts, of which the parts B and B are L- shaped and screw on the middle part B as is plainly shown in Fig. 1. From the middle part B of the pump-barrel extends upward an offset-pipe O, bent at its upper end to form the outlet-spout C, in the usual manner, and supported near its upper end on a suitable bracket 0 resting on the floor or ground on which the pump is used. From the horizontal parts of the barrel parts B and B extend downward the inlet-pipes D and D, respectively, provided at their lower ends with suitable valves E and E, respectively, opening inward and self-closing. Valves F and F are also held in thehorizontal parts of the barrel parts B and B the said valves open ing inward into the middle part B and being also self-closing.

In the vertical parts of the pump-barrel parts B and B are held to slide plungers G and G, respectively, provided with plungerrods H and II, respectively, pivotally connected with the outer ends of a balance-lever I, fulcrumed in its middle on two journals J, projecting from a block J held on the discharge-pipe O, and secured in place on the latter by clamping-bars J engaging the block J and pressed in contact with the dischargepipe 0 by nuts J screwing on the inner threaded parts of the journals J. (See Fig.

4:.) By loosening the nuts J the block J and the clamping-bars J with the lever I, can be readily shifted on the discharge-pipe C to bring the said balance-lever to the proper place, after which the nuts J 4 are screwing up to secure the block J 2 in the proper position.

The ends of the balance-lever J are connected by links K and K with the second balance-lever L, fulcrumed on journals N of a clamping device N, similar to the clamping device J above referred to, and also held near the upper end of the discharge-pipe C. The balance-lever L is provided at one end with a handle L, to be taken hold of by the operator when operating the machine.

On the discharge-pipe O are held two collars O and O, of which the former is located at or near the'surfaoe of the ground or platform, while the other is located near the lower end of the pipe G. In the two collars O and O is mounted to turn arod P, provided on its upper end with a handle P and hollow at its lower end, as shown in Fig. 5. The extreme end of the hollow rod P is fitted to turn in an offset Q, formed on the pipe 0., and provided with an inwardly-extending opening Q ,leadingto the interior of thepipe G. The opening Q is adapted to register with an opening P formed in the hollow end of the rod P, so that when the two openings Q and P register water contained in the pipe 0 above the offset Q can flow out through the openings Q and P and the hollow end of the rod P, so as to prevent freezing of the water in the pipe 0, during cold weather. Ordinarily the openings P and Q do not register.

to the barrel parts 13 and 13 and on the downward stroke of the respective plunger the valve E or E, respectively, is closed, while the valve F or F, respectively, opened, and the water is forced to the middle part B of: the barrel, and from the latter through the outlet-pipe (J and the spout Uto a receptacle held under the said spout.

It will be seen that as one plunger is moving downward the other moves upward, so that a continuous stream of water is forced up through the outlet-pipe C. It will be fur ther seen that the barrel B can be easily taken apart in order to get atthe valves and to clean the said barrel whenever necessary.

The levers I and L can be readily adjusted on the outlct-pipe C, so as to bring the links K and K, the plungenrods It and II, and the pl ung'ers G and G in proper position relative to the barrel 1;.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In a double-acting pump, the combination, with the vertical discharge-pipe, the U- shaped barrel, the valves, and the pistons, of an upper and alower horizontal lever, both having central openings between their ends to receive the discharge-pipe, upper and lower blocks sliding on the said pipe and having journals on which the sides otthe open parts of said levers are mounted, and vertically extending elamping-bars at opposite sides 0t said bloclcs and bearing at their ends on the discharge-pipe, nuts on the trunnions within the open parts of the lovers to clamp the block in place, connections between the ends of the lower lever, and the pistons and rods connecting said two levers, substantially as set forth.

2. The combination, with an apertured block J having journals or trunnions J on its opposite faces, screw-threaded at their inner portions, of opposite bars J J of greater length than the block, mounted on the inner ends of the trunnions and recessed to fit on the block and project at their ends inwardly to the bore or aperture, and nuts on the trunnions bearing on the outer faces of the bars, substantially as set forth.

8. In a doul'ile-aeting pump, the combination, with the discharge-pipe, of a block having journals held to slide on the said disc11arge-pi1 )e, clamping bars fitted on the said block and adapted to engage the said outletpipe, and nuts screwing on the said journals against the said elamping-bars to press the latter in contact with the said outlet-pipe, substantially as shown and described.

JOSEPH M. CLARK.
