VALVE.

Application filed May 3,

To all whom a: may concern.

Be it known that I, THOMAS JOHN Mo- KENZIE, a citizen of the United States, residing at Barberton, in the county of Summit and State of Ohio, have invented new and useful Improvements in Valves, of which the following is aspecification.

This invention relates to improvements in foot valves, the principal objectof the invention being to provide a valve of this nature which can be manufactured to sell at low cost and which has great wearing qualities due to the use of metallic parts only.

Another object of the invention is to make the device of but three parts, one of which includes a strainer with means for quickly and easily assembling the parts.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation of the invention.

Figure 2 is a longitudinal sectional view.

Figure 8 is a view of the valve member.

As shown in these views the body A of the device is of bulbous form and is formed of two parts 1 and 2. the two parts being screw threaded together, as shown at 3. The bottom of part 2 is provided with an extension 4 which is perforated as at 5 to form a strainer, this extension being of tapered formation and wider at the bottom than at the top. An imperforated part 6 separates the perforated part from part 2 and at the junction of this part 6 to part 2 a valve seat 7 is formed. The interior wall of this part 6 is cylindrical while its exterior wall is provided with a plurality of flat sides, as at 8, to form a wrench receiving part. A cross bar 9 is carried by part 1 and this bar has a hole 10 therein. The valve member 3 is adapted to engage seat 7 and its stem has an upper reduced part 11 1921. Serial No. 466,599.

for engaging the hole 10, this reduced part forming a shoulder 12 which will engage the bar 9 and thus limit the upward movement of the valve. The valve member also is provided with the downwardly projecting fingers 13 which are adapted to engage with the cylindrical interior wall of part 6 for guiding the valve member in its movement. The upper end of part 1 is provided with interior screw threads 14 so that it can be secured to the lower end of a pipe and the upper exterior wall of this pipe is provided with a plurality of flat sides for receiving a wrench.

From the above it will be apparent that the device will have great wearing qualities as the entire device is formed of metal and there is no leather or rubber parts to wear out. It will also be seen that the parts can be easily and quickly assembled and that the device can be manufactured at low cost.

The action of the water or other fluid acts as a cushion on the downward thrust of the pump plunger and all noise and vibrations are eliminated. The slightest touch on the pump handle or rod on the Lip-stroke causes the water to flow past the valve. A pump equipped with my improved foot valve can remain in a well indefinitely as there is no necessity to take up the piping in order to repair the worn leather parts as is the case with the valves as now constructed.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may i make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall Within the scope of the appended claim. lVhat I claim is A foot valve of the character described comprising a two section body of bulbous form threadedly secured together, a tapered perforated extension depending from the lower section and converging upwardly, an imperforated part separating the perforated extension from the upper portion of the last mentioned section, a valve seat formed at the junction of the section and the imperforated part, a valve member designed to normally engage the seat, a crossbar arranged in the upper section and being provided with an opening in its center, a stem rising from the valve member and being provided With a reduced portion designed to pass through the opening, a shoulder formed by the reduction and being adapted to en- THOMAS JOHN MQKENZIE.
