IMPROVEMENT I N PUMPS.

` Speciiication forming part of Letters Patent No. 173,6 l2, dated February 15, 1876; application iiled July 26, 1875.

Vconstruction and arrangement of a wooden force-pump, as will be hereinafter more fully set forth. In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in Which- Figure l is a longitudinal section of my pump; and Fig. 2 is an enlarged section of the pump-cylinder.

A represents the hollow pump-stock, of any suitable dimensions, closed 4at itslower end and inserted in the Well. To the Side of the pump-stock A, near the lower end, is fastened the pumpcylinder B, by means of metal straps or bands G'G. The pumpcylinder B is near its upper endconnected-with the pump-stock A by a suitable passage, which is provided with a check-valve, a. The bot tom B of the cylinder B is provided with suitable passages b for the ingress of waterV into the cylinder, and on said bottom is a check-valve, d. The bottom is provided with a flange, w", to allow of its insertion to the proper depth within the cylinder. It is also provided with recesses y', into which the hooked ends of the rods h are inserted. The

pump-plunger is composed of a cylindricalA body, D', with perforated heads E E, Vthrough the center of which latter passes the' screwvrod f. On this rod above or on top of the upper head is placed a valve, Gr, which moves vertically up and down on the rod, its movement being limited by a pin or collar, e, on the rod f. In the upper end of the cylinder B is inserted a head, H, in the under side ot' which are made recesses a: w, toA receive the stop c, and top of the valve, when the plunger is raised. The rod f passes through the center of the head H, and around the rod in the top Y of the head is a recess for the reception of packing Over the head H is placed a metal plate, I, fastened thereto by screws or other suitable means, and provided with projecting ears, through which pass rods 1th, as shown in Fig. 2. The lower ends of the rods It are bent in hook form and inserted in the bottom of the cylinder. Nuts y y are then screwed on the' rods It, against the projections on the plate I, thereby making all the parts tight and uniting them firmly together. Above the plate I, on the rods h h and plunger-red f, is placed a cross-bar, J, which is provided with a downward-projectin g hub, 7c, extending down through the plate I into the recess in the head H on top ofthe packing t'. The cross-bar J is pressed downv and held by means ot' nuts z z, screwed upon the upper ends of the rods h h. The plunger rod f extends upward through suitable guides m attached to the pump-stock A, and is jointed atn to the lower end of a rod,f', the upper end of which is connected to oneend ot' the lever L. The lever passes through and is pivoted in the pump-stock A. Around the upper end ot' the pump-plunger is a packing., p, of leather or otherV suitable material.

- In operation the pumpcylinder B isalways submerged in the water, and it will be seen that by raising the handle end of the lever L the plunger is forced downward, opening the valve G, land causing the water to pass through above the valve. By depressing the lever the plunger is raised, forcing the water into the pumpstock and ont of the spout O.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, isf A The combination of the pump-cylinder B, head H having recesses in top and bottom, plate I, cross-bar J, with hub k, packing t', and hooked rods h h, with nuts y z, and the removable bottom B, provided with valve d, iiange it', and recesses y', all substantially as and for the purposes herein set forth.

In testimony that l claim the foregoing I have hereunto set my hand this 29th day of April, 1875.
