AUTOMATIC vALvE.

Application med June so, 192'5. serial No. 40,583.

To all whom z't may concer/n.: Be it known that we, EDWARD G. KELLEY and CHARLES ZrRKLE, citizens of the United States, residing at Greenville, in the countyL of Darke and State of Ohio, have invented certain new and useful Improvements 1n AutomaticV Valves, of which the following is a specification. Y

This invention relates to valves and pertains particularly to an automatic air valve for use in connection with seat actiontoilets making use of a compression tank.

The primary object of this invention is the kprovision, in a manner as hereinafter set flowing water and thus held in the compressed condition until the tank is again empty. The -air thus compressed in the tank will assist in the ready and complete evacuation of the same upon the flushing of the toilet.

.A further object ofy the invention is the provision, ina manner las hereinafter set forth, of an automatic air valve for thetuse above set forth, in which, in the event that through some defect the valve ceases to operate, the valve will become closed so that no air can enter the compression tank thus causing the imperfect action of the tank and drawing attention to the fact that the valve is not operating properly.

A further and final object of the invention is the provision, in a manner as hereinafter set forth, of an autom-atie air valve for the purpose above set forth, which will be of simple construction, strong and durable, and efficient for the purpose for which constructed.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming a part of this specification, with the understanding that the invention is not confined to any strict conformity with the showing of the drawing but may be changed and modified appended claims.

In ,the drawing: Figure 1 shows the device embodying this invention, in side elevation. p

Figure 2 is a longitudinal sectional View through the device. Figure 3 is a top plan view of the same.

VFigure 4 is a p an view of the oat and check element forming a part of the interior .construction of the valve.

i Figure 5 is asection taken upon the line 5--5 of Figure2.

Figure 6 is a side elev-ation of the check valve used in the main valve structure and, Figure 7 is the bottom plan view of the check shown in Figure 6.

Referring now to the drawing in detail wherein like numerals of reference indicate corresponding parts throughout the several views, the device embodying this invention comprises a head 1, the lower portion of which head is constrieted as indicated at 2 and terminates in the reduced annular portion 3. The upper or larger portion of the head 1 is hollowed to provide the longitudinally extending chamber 4, the upper portion of which chamber has the wall thereof threaded as indicated at 5. The lower portion of the head has a central longitudinally threaded as indicated at 11, and engaged` over the other end of this nipple 10 is a reducing coupling 12 into the reduced end 13 of which a second nipple 14 of less diameter than the nipple 10, is threaded. This nipple 14 also has each .end threaded as indicated at 15, and the other free end of this nipple is adapted to be connected to and lead into a compression tank (not shown).

Threaded into the passage 8 and engaging threads 9 formed in the wall thereof 1s a relatively long tube 16, the lower end of which is reduced as at 17 and headed as shown, to receive thereover the open end of a rubber check 18. `This check has an annu lar groove 19 formed thereabout in which a securing wire 2O is adapted to be placed, which ends of the wire are twisted to hold 'gagement with the headed reduced end of the tube 16. The check 18 has formed upon and across the other end the thickened rid e 21 and there is formed in this ridge the s it 22 which opens into theinterior of the check as clearly shown' in Figure `2. As will be explained further on this check allows air to pass from the tube 16 into the nipples 10 and 14 and the coupling 12 and prevent any airfrom flowing' back from these elements into the tube.

The upper open end of the chamber 4 1s closed by a plug indicated generally by the numeral 23. This plug comprises an enlarged peripherally threaded annular portion 24 and a polygonal shaped extension`25. Extending longitudinally -through the extension 25 of the plug is a bore 26'the lower end-of which opens into the annular recess 27 which is of greater diameter than the bore as is shown in Figure 2 and this annular recess in turn opens into the arcuately recessed lower side `of the enlargedportion 24 of the plug as indicated at 28. 1

Extending longitudinally through the plug 23 and through the chamber 4 of the head 1, is a rod member 29 threaded throughout as shown.- At approximately the central portion ofA this rod there is positioned a float 30, through the central portion of which the rod passes and upon the lower side of this loat is a retaining plate 31 held in position and in turn holding the lloat in position ipon the `rod by means of thenut32.-

Upon the top of the float 30 is a semispherical rubber seat washer 33, the flat surface of which bears against thejtop of the float 30 while the curved portion is adapted to seat against the edge formed in the plug between the recesses 27 and 28, under certain conditions. The threaded rod 29 passes through this washer as is shown. p p

Threaded upon the rod 29 is a securing nut 34 which bears against the top of the washer 33 and over this nut is a cup washer 35 held in position by the nut 36. This cup washer under certain conditions, when the washer 33 seatsv upon its seat, moves into and closes the annularrecess 27. Upon the upper end of the threaded ro 29 which extends beyond the top of the plug portion 25 is a pair of stop nuts 37 which prevent the rod 29 and elements carried thereon from moving downwardly further than is desired.

The top surface of the polygonal'extenf sion 25` of the plug is transversely slotted as indicated at 38 thus when the ynuts 37 are resting upon the top of the portion 25 they will not close the aperture or passage 26 against the passage of air therethrough as the air will enter the passage 26 through the slit 38.

This valve structure just described is adapted to be lattached to a compression tank of a seat action toilet, andwhen vthe toilet l is flushed lthevacuum created in the tank through the water leaving the discharge port thereof will cause air to be drawn in through the passage 26 past theopen valves 33 and 34 and through the chamber 4 and `tube 16, through the check 18 and into the tank; When the tank has become completely empty of water, it will then be illed with air and due to the closing of the slit 22 in the check 18 this air in the tank will be trapped and cannot leave the same. When the water begins to flow into the tank to refill the same it will compress the air trapped therein as it rises and thus when the tank is again flushed this compressed air will act to yforcefully eject thewater from the tank intothe toilet bowl thus causing a complete and better 4flushing of the bowl than would be obtained if the water flowed from the tank through gravity only.

Under all normal conditions the float 30 will be down and thevalves 33 and 34 will be unseated. In the event that the check 18 fails, through the rotting of the rubber or from anyother cause which would allow the water from the tank to ilow back up through the tube 16 into the chamber 4 instead of being stopped by the check the float would be raised by )the water `raising the valves 33 and 34 to closethe passage through 'the cap23 thus preventing the water from escaping through the valve. The cup valve 34 will be forced into the recess 27 when this happens and will frictionally engage the wall thereof, and when the tank is flushed and vwater leaves the same l the frictional contact of this cup valve 34 will prevent the ,float and valve from dropping thusl preventing the air from being drawn into the tank as the water leaves the same. This will .cause a faulty operation of the tank and will in dicate that the valve is not working properly so that an immediate repair can be made to the valve to restore the nor mal working condition of the same.

Having thus described our invention what we claim is 1. A valve of the character described comj of the failure of said check.

2. A valve of the character described comprising, a head having a chamber formed longitudinally therein, a centrally apertured plug closing the open end of said chamber, means for setting up a tubular connection between said chamber and a toilet compression flush tank, means in said tubular connection allowing air to llow only through saidhead into said tank, and automatically operating means for closing the aperture in said plug in the event of the failure of said means in the tubular connection.

3. A valve of the character described com-` said head into said tank, and a float element within said chamber acting to bring about the closure of the aperture in said plug in the eventgof the failure of said check.

4. A valve of the character described, comprising, a head having a chamber formed longitudinally therein, a centrally apertured plug closing the open end of said chamber, means for setting up a tubular vconnection between said chamber and'a toiletcompression flush tank, a one Way check in said tubular connection allowin airto low only through said head into said tank, a shiftable rod extending longitudinally through said chamber, and through the aperture of said. plug, afloat carried upon said rod adapted to be shifted by water backing into said cham ber from said tank, in the event of the failure of said check, and means carried by said rod operating to close the said aperture When said oat is raised.

5. A valve ofthe character described, comprising, a 'head having a chamber formed longitudinally therein, a centrally apertured plug closing the open end of said chamber, means for setting up a tubular connection between'said chamber and a toilet compression flush tank, a one way check in said tubular connection allowing air to How only through said head into said tank, a shiftable. rod extending longitudinally through said chamber and through the aperture of said plug, a float carrled upon said rod adapted to be shifted by Water'backing into said chamber from said tank, in the event ofthe failure of s aid check, means carried by said rod operating to close the said aperture when said float is raised, and means en- 1 gaging the wall of said aperture, upon the closing of the same by said last mentioned means, whereby the aperture willbe maintained closed independent of the operation of said float. Intestimony whereof, we affix our signatures hereto. a
