SPECIFICATION forming part of Letters Patent No. 619,645, dated February 14, 1899. v Application filed December 27,1897. Serial No. 663,598. (No model.)

To all whom it may concern,.-

Be it known that I, HERMAN WALTHER, a citizen of the United States, residing at Bloomfield, in the county of Davis and State of Iowa, have invented certain new and useful Improvements in Pumps; and I do hereby 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 it appertains to make and use the same.

My invention relates to improvements in pumps, and has special reference to the class of pumps commonly known as force-pumps.

The main object of my invention is the provision of a force-pump which will be easily op'- erated,which can be readily and easily cleaned or taken apart, which has a device automatically operated to prevent freezing, and which isvery simple, durable, and inexpensive, thus producing a practical and useful force-pump.

To attain the desired objects, the invention consists of a force-pump embodying novel features of construction and combination of parts, substantially as disclosed herein.

Figure 1 represents a vertical central sectional view of my improved force-pump, and Fig. 2 represents an enlarged vertical central sectional view of the lower portion of the forceump.

In the drawings, A designates the main pump-barrel, whose top is covered by the lid or cover B and whose lower portion C is tapered, the whole barrel being made of galvanized sheet metal or any sheet metal which would answer the purpose. In the hollow central portion of the barrel is placed the auxiliary barrel D, which is provided with the spout-pipe E at its upper end,which is opposite the opening F in the main pump barrel or casing, and has connected to its outer end the spout G, whose end passes through the opening F. Near the lower end of the auxiliary barrel is the screw-threaded enlarged mout-h Il, which has secured thereto the cylinder J, which has one of its ends screw-threaded to connect it to the mouth of the barrel D and its lower end contracted upon inclined lines to receive the enlarged upper end of the ring K, having the opening L in the center thereof controlled by the flap-valve M, which flaps inward or upward to allow the water to fiow in the cylinder. This ring is driven into the lower end of the cylinder J and there tightly held, as seen in Fig. 2, and it terminates in the depending tube K.

Adapted to slide upward and downward in the cylinder and snugly fitting therein is the plunger N, which consists of the ring O, having the peripheryT I, to which is secured the piston-rod-connecting means or band Q, and secured in between the periphery over the central opening of the ring is the valve S, which is adapted to flap upward to allow the water to ow above the plunger and up through the auxiliary barrel and out of the spout. Passing through the center of the auxiliary barrel is the piston-rod T, which has its top connected to the handle U, and its lower end is connected to the plunger N.

On the side of the cylinder J, nearthe upper end thereof, is an opening V, in which is secured the elbow WV, over whose mouth fits the valve X, carried by the expansible rod X', which has its upper end passed through the bracket Y and provided with adjustingnuts upon opposite sides of the bracket, as seen in Fig. 1, and carries at its lower end the rubber seat Z, which is adapted to expand and close the mouth of the elbow or contract when the weather is very cold to allow the water to flow, and thus keep it from freezing and bursting the pump-casing.

I would have it understood that the pump and nearly all of its parts can be readily made of sheet galvanized iron or other suitable sheet metal and that wherever washers or nuts may be used I employ them without in any way departing from the nature of my invention.

From this description, taken in connection with the drawings, the operation of my improved force-pump will be readily understood, but, brieiiy stated, is as follows: The

.pump-casing and parts are put in position,

as shown in Fig. 1, and they are then ready for use. It will be seen that by forcing the handle downward the piston-rod is raised, causing the plunger to rise upward and causing a suction enough to raise the Hap-valve at the bottom of the cylinder, and on the downward stroke the valve of the plunger rises, allowing the water to pass upward above the plunger, so that when the handle is forced downward again the water is forced upward IOC through the auxiliary barrel and out through the spout.

It is evident now that I provide a forcepump which is easily operated, which is readily and easily placed in position and taken apart, which is provided with a device which doesnot allow the water to be aiected by the temperature of the atmosphere, and which is extremely simple, durable, and cheap, as well as useful and practical for the intended purpose.

I claim- In a force-pump, the combination of the tapered main pump-casing, the auxiliary barrel having at its lower end an enlarged mouth with its lower vertical wall tted within the lower end of the casing with the inner face threaded, the cylinder having its upper end threaded to engage the threads of the said mouth and its lower end contracted on inclined lines, the tubehaving enlarged upper end with tapered outer wall engaged tightly in the contracted lower end of said cylinder, Hap-valve on the upper end of said tube, a piston-rod passed through the auxiliary barrel into the cylinder, and a valve on the lower end of said piston-rod and working in the cylinder, all substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

HERMAN WALTHER.
