Patented Get, l, 159529 GEORGE AZONE, OF PHILADELPHIA, PENNSYLVANIA .AIR 'VENT FOR Application filed October 6,

My invention relates to a new and useful air vent for siphon flush boxes of the siphonjet type whereby the air pressure in the air pocket, formed between the level of the water inthe tank and in thetoilet bowl, is relieved to facilitate the flow of water from said tank to said bowl, thereby increasing the force of pressure of the water and augmenting its cleansing capacity.

In certain conventional installations the waterinjected into the toilet bowl from the siphon flush tank is retarded in its downward iow with the result that a considerable amount of the force of the water is lost. This `\l5 is evidenced by the fact-thattllejlow of'water intorand through the tpilet bowlisatfirst# rather slow and interrupted, the speed of the flow of the water increasing gradually, as the air in the air pocket formed in the pipe connecting the flush tank to the bowl is gradually released till a siphon effect is produced after all of the air in said air pocket has escaped.

Since the ability of the water to clean the s toilet bowl depends primarily upon theforce and speed with which the water flows, it is evident that by thus relieving the air pressure and permitting the unopposed, rapid flow of water to create a maximum siphon effect, a maximum efliciency is obtained, whereby the necessity vfor manual cleaning of thetoilet bowl is greatly reduced. To the above ends, my invention consists of a novel siphon Hush box provided with an auxiliary air vent communicating with the air pocket referred to and leading to ,the atmosphere, whereby, when the water flows ydown through the main conduit, the air in said air pocket will escape through said air vent, thereby permitting the uninterrupted,

'40 unretarded flow of water at full speed and with maximum force. .y The invention consists of the novel construction hereinafter described and finally claimed. l5 For the' purpose of illustrating my invenltion I have shown in the accompanying drawings one form thereof which is at present preferred by me, since-the same has been found'in practice to give satisfactory and reliable results, although it is to be understood SIPHON FLUSH 1928. serial No. 310,702.

that the various instrumentalities of. which my invention consists can be variously arranged and organized and that my invention is not limited to the precisearrangef ment and organization of the instrumentalil 5': ties as herein shown and described. The ligure represents a vertical section of anjair vent embodying my invention.

Referring to the drawing, 1 designates an upper tank or reservoir having the bottom` 2, top 3, and sides 4. A water supply pipe 5 leads into the tank 1 and is provided with the valve 6, controlled by the/Hoat 7 through the arm 8 in the usual marmer. 10 designatesl a pipe adapted to communicate with the slil'p- 65 V pl-yipipewhen 4the valve 6 is opened to the tank 1 with water after each flushing or emptying of the tank. 11 designates a gravity limb or discharge pipe extending downwardly through the bottom 2 of the tank into the 70 toilet, bowl 12 and having its upper end connected to one end of an inverted U-shaped coupling 13, to the other end of whichis connected the main siphon pipe 14 which is provided with the branch Siphon pipe 15, '75 said pipes'15 and 14 being at an acute an le to each other. A relief pipe 16 connects'tlie casing of the valve 6 with the upper end of the gravity discharge pipe 11 through thel coupling 13, while an auxiliary pipe 17 pro- -80 vided with. the nozzle 18, juxtaposed .to the lower end of the branch pipe 15, 'communie catesat its other end with the valve 20 through thecoupling 2l. f

IIn a flush box construction lof the character described, the airo confined between the level ofthe water 23 in the main Siphon pipe 14 and the level of the water 24 in the trap 25 forms an air cushion -which lretards the flow of water from the tank down through the pipe 9o 11 into the trap y25 of the toilet bowl 12 when the closet is flushed. To allow the air thus confined to escape and thus eliminate the resistance'o'f the air cushion referred to, I provide the vent tube 26, the lower end 27 of 95 which extends int-o the upper portion of the trap 25 above the water level therein, and the upper end 28 of which extends upwardly through the tank 1 above the level of the water therein. By my novel construction, the

aii confined in the pipe l1 1 and trap 25 escapes ythrough the vent tube 26, thus producing a maximum siphon effect and allowingthe ywater to flow uninterruptedly through the gravity pipe 11 and trap 25 through the port y 27, with maximum force and speed, so that a quicker, more thorough and more eflicient flushing of the toilet bowl is obtained.

It will be evident that my novel air vent 26 functions by balancing the air pressure within and Without the discharge pipe ll and` creasing volume and a pressure results which is in excess ofthe normal atmospheric pressure exerted in the upper portion of the tank l, thus hindering or retarding the flow of water.

It is to be lnoted that while my novel air vent is adapted for use in connection with a great variety of siphon flush boxes for toilet bowls, the accompanying drawing merely illustrates the application of my novel air vent to a siphon flush construction of the character disclosed in my Patent N o. 1,563,948, and to which reference can be had for a more detailed description of the Siphon apparatus proper.

I am aware that the invention may be embodied in other specific forms without departng from the spirit or essential attributes thereof, and I therefore desire the present embodiment to be considered'in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope ofthe invention.

The discharge pipe l1 and the air vent tube 26, extending downwardly through the/bot-v tom of the tank l, are provided with the Wa ter tight joint 30 which comprises the sleeve 3l having the flange 32, the space between said` pipes and said sleeve being filled with solder, plaster of Paris or any other suitable Water tight filler or packing 83. A gasketBt is interposed between the flange 32 and the edge of the bottom wall 2 and the nut 35 is tightened around the lower threaded portion 36 of the sleeve 31 to assemble the joint.

Similarly, the lower ends of the pipe 11 and tube 26 are secured to the top of the toilet bowl l2 by the water tight joint 37 comprising the externally threaded sleeve 38, the gasket 39 and the nuts 40 and 4l which are tightened around the threaded sleeve 38, the space ybetween said pipes being filled with solder or any suitable water tight packing 42 as may be desired.

Having thus described my invention what I claim as new .and desire tosecure by Letters Patent, is
