VALVE Specification of Letters Patent.

Patented July 14, 1908.

Application led October 18, 1907. Serial No. 398,095.

To all whom fit may concern: i

Be it known that I, DELL W. JEWELL, a citizen of the United States, residing at Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented a new and useful Valve, of which the following is a specification.

This invention relates to lushing valves for use in connection with closets and its object is to provide a simple device of this character having means whereby the valve is automatically locked when opened, there being means for unlocking the valve and returning it to its closed position after a predetermined period.

Another object is to provide simple means for regulating the length of the flushing periods.

Another object is to provide means whereby the valve can be quickly reset automatically as soon as closed.

A still further object is to provide novel means whereby leakage within the valve may be conducted to the outlet of the valve so that all of the parts will be maintained in operative condition.

With these and other objects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawingsV is shown the preferred form of the invention.

In said drawings. Figure 1 is a section through a valve embodying the present improvements and showing the positions of the parts while being set. Fig. 2 is a similar view and showing the positions ofthe parts duringthe flushing operation. Fig. 3 is a transverse section through the main valve.

Referring to the figures by characters of reference, 1 designates a substantially cylindrical housing having a screw cap 2 which constitutes a closure for one end while the other end of 4the housing'is provided with a slidable stem 3 having a head 4 at its inner end and a knob or other suitable enlargement 5 at its outer end. This housing is intersected between its ends by a passage 6 extending through a tubular extension 7 designed to be connected to a supply pipe, not shown, and said passage also extends through a tubular member 8 projecting from the-housing 1 and alining with the extension 7 although preferably of slightly greater diameter. This extension 8 is designed to be connected to the bowl in the usual or any preferred manner.

Opening into the extension 7 is a preferably cylindrical housing 9, the outer end of which is preferably closed by means of a screw cap 10. passage 6 and the interior of the housing 9 is established through a port 11 having a valve seat 12 surrounding it. A check valve 13 is iitted within the port 11 and normally rests Communication between the upon the seat 12 and this check valve has a small passage 14 extending through it. A compartment 15 is formed between the housings 1 and 9 and opens into the housing 9 through a passage 16. Adog 17 is fulcrumed Within compartment 15 and has an arm l 18 extending through the passage 16 and into the housing 9. An opening 19 is formed in the bottom of compartment 15 and a spring 19 is connected to the dog and bears against valve 13 so as to hold the valve f normally upon its seat and the end of the dog normally within the opening 19.

A valve 20 is slidably mounted within the housing 1 and has a passage 21 therethrough designed to register with the passage 6. A tubular extension 22 is formed with the valve and is slidably mounted within the housing 1 and this extension has one or more longitudinal grooves 23 into one of which extends a screw 24 or other holding device for the purpose of preventing the rotation of the valve and its extension. A spring 25 is arranged within the housin@P 1 and projects into valve extension 22. T is spring bears against the screw cap 2 and,

holds the valve 20 normally against one end of the housing so that the passage 6 is closed by the extension 22 as shown in Fig. 1. A

notch or recess 26 is formed in the extension 22 and is designed to receive the dog 17 when the valve is moved into open position. The valve is thus locked as shown in Fig. 2 until released in the manner hereinafter described. A release device in the form of a follower 27 is slidably mounted in housing 9 and a spring l 2S which bears against the screw cap 10 holds the follower normally against arm 18 as shown by dotted lines in Fig. 2, thus drawing the dog 17 out of engagement with extension 22 and releasing valve 20.

A controlling device 1n the form of a threaded stem 29 engages the extension 7 and has a pointed end 30 in the form of a needle valve which is designed to project into andpartly close the passage 14 in valve 13. A bypass 81 connects the housings 1 and 9 close to the screw caps so that any water which may leak past the follower 27 will be free to flow downward into housing 1 and thence through the groove or grooves 23 to the outlet extension 8.

When valve 2O is in closed position with extension 22 extending across passage 6 the water under pressure will force valve 18 open against the stress of spring 19. The water will therefore enter the housing 9 and force the follower 27 toward the screw cap 10 thereby placing the spring 28 under stress. -As soon as the pressure becomes equalized at both sides of the check valve the same will be reset by spring 19/.

To operate the device for flushing purposes stem 3 is pushed inwardly against valve 2O and said valve is therefore shifted longitudinally against the stress of spring 25 until the passage 21 registers with passages 6 and notch 26 assumes a position opposite the opening 19. Spring 19 will then promptly throw the dog downward into the notch and the valve will thus be locked open. The water will then be free to flow directly from the source of supply through passages 6 and 21 and the spring 2S will force follower 27 longitudinally so as to slowly discharge 'the liquid contents of housing 9 through the passage 14, the speed of discharge being regulated by the stem 29. Just prior to reaching the limit of its forward movement the follower strikes arm 1S and swings dog 17 out of notch 19 whereupon spring 25 promptly shifts the valve 20 longitudinally so as to close the passage 6. The water will then be a ain directed into housing 9 as heretofore escribed and the foregoing operation will be repeated. It will be obvious that by adjustino' the stem 29 toward or from the check valve the time required for the water within housing 9 to escape therefrom can be regulated and the length of the flushing operation correspondingly controlled.

t will be seen that the device is very simle, durable and eflicient and that access can e conveniently had to all parts thereof.
