To all `whom t may concer/nf.'

e it known that I, DUDLEYNEWTON, a citizen of the United States, residing at San Francisco, in the county' ofSa'n Francisco 5 and yState of California, have invented new and useful Improvements A in Devices for Flushing `Toilet Fixtures, of which the following is a specification.

The present invention relates to apparatus for automatically flushing toilet fixtures such as water closets, urinals and the like and has special regard to certainimprovements in apparatus of the character embodied in United States Letters Patent, Numbers 1,201,752` andv 1,328,445, issued to me on Oct. 17, 1916,and J an. 20, 1920, respectively. The primary object of the invention is to provide apparatusof the character described which will be more simple as to construction, less expensive, more compact, easier to install and take down and also easier to clean, than similar apparatus heretofore used; these objects being attained principally thru the use of a novel and simplified form of sipho-n apparatus and by reasonv of the manner of housing and positioning or the locat ing of the same. v

The invention possesses other advantages and features some of which, with the foregoing [will be ,set forth atlength in the following description where I shall outline in full that form of the invention which I have selectedv for illustration in the drawings accompanying and forming a partof the present specification.' In said| drawings I have shown one form of the construction of my invention, but it is to be understood that I do not limit :myself to such form since the invention as expressed in the claims may beembodied in a plurality of forms.

yReferring' to the drawings; F'gure 1 is a fragmentary vertical sectional view of the apparatus of this invention shown applied to a urinal. Figure 2 is an enlarged vvertical fragmentary section` thru the flushing tank taken at right angles to Fig. 1.

Figure 3 isan enlarged fragmentary verti-- cal sectional view taken thru the fixture bowl and showing the siphon construction.

Figure 5 Ais an enlarged vertical sectional view of a modifiedl form of fixtureand si# phonlconstructed of metal.

i Figure ,6 is top plan view'r'ofthe apparatus l i shown in Fig. 5. .f Y

The present embodiment ofthe invention as shown in the ,drawings comprises aurinal 1 of porcelain, supported on the usual back or wall slab 2 behind which is a flushing tank 3 supported in any suitable ina-nner above lthe urinal. The tank 3 contains lthe usual filling and level control apparatus, not

shown.

comprises a Icover 5 or airfcontainer thru ythe top of which an air inlet pipe extends .leg leads to and is formed integral with 'a trap 8. Asho-rt pipe QcO-mmunicates ywith the outlet endof the trap, extends thru t.he back 2 and is connected with a yflushing pipe 10 which latter extends into the top of the urinal.

A pipe llkleadsfrom the inlet side of the trap 8 downwardly, then thru-'the back 2 at a point below ythe urinal and then kupwardly as at 12 whereby a trap as shown at 13 is provided inthe pipe 11. The lower side of the porcelainurinal 1 is enlarged and thickened as at-14, and has an outle-t or discharge opening 15 therein, A perforated screen or guardi plate y16is removably fitted in a countersink 17 in said opening.v A drain or outlet passage l1 E5`yis provided in the portion`14 and is of less diameter than the opening 15,1s'o as to provide for theformation-'of siphoni elements below but in registration with saidopening 15V. A drain pipe 19 is connected in the usual V y A Siphon is'inounted in the tank 8,- and manner with the urinal` andy registers` with y the passage 18. e Y n y,

Siphon ymeans is housedl within the len,-A larged portion-14 of theurinal and comprises a rectangular chamber 20 having'lits from the core portion 24 and from the guard plate 16.

A siphon conduit 25 is formed in the core portion 211 and extends thru the portion 14 to the lower side thereof, where it is co-nnected as at 26 with the upper end of the pipe 11. A similar condluit 27 is formed in the portions 14k and 24 and leads into the lower end of the drain passage 1S. The up` per ends of these passages 25 and 27 are approximately in the same plane at the top of the core 24 which latter terminates below the cover. The passage 25 is virtually an extension of the pipe 11 and a part of the trap 13.

Operation.

After a. iushing operation and the tank is empty, the water is left at the level of the pipe 9, in the trap 8, and the pipe 11 draws the water from the intake side ofthe trap whereby the water in both sides of the trap is brought tc the same level, namely, the top of the pipe 11. The pipe 11 conducts the water to the trap 13, to the upper end of the passage 25 from which the water spurts or flows with sufficient force against the cover plate 16 to dislodge any foreign matter which may have been lodged in the' chamber 20. This also prevents clogging of the passage 25 and other siphon elements in the urinal, as these parts are thoroughly flushed by the action above described, after the flushing of the urinal. After the trap 8 is drained to the level of the top of the pipe 11, the level of the water in the pipe 11 descends until it reaches the level at the top of the passage 25, or in other words, balances in the trap 13. The water in the chamber 2O both on the inside and outside of the cover will siphon out thru the pipe 27 and the level thereof will be brought below the upper ends of the conduits 25 and 27.

lVhen the tank 3 begins to lill, air which has entered thru the pipe 6 into the cover 5 and pipes 7 and 11 will be compressed by the water and the water is forced out of the intake sides of the traps 8 and 13 into the outlet legs'or sides of said traps. The force of the air upon the top of the column of water in the cover 5 causes the level of this column to be maintained below the upper end of the pipe 7 'so as to prevent iow of water out thru said pipe. The action of the compressed air maintains the traps with the outlet sides filled and the intake sides practically free of water, the air sustaining the weight of the columns of water in the outlet sides of the pipe so that the level of the water is at the pipe 9 in one instance and at the top of the passage 25, in the other instance. lVhen the flushing tank is filled the pressure of the air on the siphons and traps is balanced by action of the weight of the columns of water and head water in the tank itself. Thus upon the slightest disturbance of this balance the flushing operation will take place. Therefore, upon use of the urinal, some of the liquid will run thru the perforated guard plate 16 into the chamber 20 whereupon the level of the water A therein will be raised. If this level is raised this water is reduced and is not suflicient.

to overcome. the air pressure in the pipe 11. The air then expands and drives the water out thru the trap 13. Simultaneously with the action in the trap 13 the trap 8 operates and the air pressure is likewise reduced in the cover 5 whereupon the water will rise in said cover until it flows into the pipe 7. The water of the tank is then free to liow into the urinal thru the pipes 7 9 and l0, and the pipe 11 and passageway 25. The head of the water in the tank also acts to siphon the tank thru the air intake pipe G and the urinal will be thoroughly flushed and the tank drained.

Aft-er flushing of the bowl and while the tank 3 is reiilling the chamber 2O will be siphoned several times. When the water is level in the trap 13,` as is the case immediately after a flushing operation, the level of the water in the chamber 2O will have been lowered to the line of perforations at the bottom of the cover, due to siphoning of the water therein out thru the passage 27 during the overflow of the pipe 11 vwhile the water in seeking its level in theV trap 13. This level in the chamber 2O will be raised during the time required in filling the tank 3, by seepage or draining of the small quantity of water collected-on the sides and bot-V tom of the bowl and due to the water forced out of the passage 25 into said chamber while the air is compressed in the pipeV 11 by the action of the water against the air in the cover 5. Vhen the level of the water in the chamber 2O reaches the level of the top ofthe passage 27 the water in said chamber will siphon out thru the passage 27 and drain the chamber until when the tank 3 is filled and the air compression ceases to force the water out of the passage 25 whereupon the level of the water in the chamber is lowered to a 4point below the tops of the passages 25 and 27 and the apparatus is again ready for an automatic flushing opertion.

The passages 18, 25 and 27 are straight, substantially upright and in line with the opening 15, when open the plate 16 may be lifted out and ready access to these passages and the chamber 2O may be had'in order to1clean out theserele'mentsl Thusitwill. ibe ,seenl that. those. elementsg requiring cleaning from time to: 4time may:` be. reached and cleaned without. disassembling Lthe ap.- 5- paratus and requirin lthe employment ofa,

A nut`35 holds the pipe lin place and a drain pipe 36 of usual form is connected to the lower end of the pipe 34.

A partition 37 integral with the pipe 34 on one side'thereof and with a horizonal bottom member 38, forms withthe wall of the pipe 34-.and member 38, a chamber' within the pip@ 34. The upper edge of this chamber at the partition side terminates short of the upper end of thepipe 34 and allows for overflow into the pipe 34. The upper end of the pipe 34 supports a perforated guard or screen plate 31-whichis removably countersunk in said upper end. A pipe 41 leads from the upperv trap, not shown, (which trap corresponds to the trap 8 and the pipe to the one 11 of the preferred form ofthe invention), thruopenings 42l and 43 in the side of the pipe 34, up into the chamber 39. A pipe 44 extends fromv4 the chamber 39, thru the bottom 38 and discharges into the pipe 36. The pipes 41 and 44 are substantially upright' in Vthe-chamber 39 and have their upper ends open in the same horizontal plane at a point near but slightly below the upper end of the chamber. A cover member45 closed at its upper end is mounted in the chamber vso as to' house the upper portions of the pipes 41 and 44, the upper ends of said pipesbeing spaced slightly below the closed end ofthe cover.
