FLUSI-IING DEVICE FOR CLOSETS.

Specification of Letters Patent.

Patented Nov. 9, 1915.

To all'whom it may concern p U Be it known that I, EDWARD Ti-I'IR'Y, a citizen of the United States, residing at Pasadena,-in the county of Los Angeles and State of California, have invented new and useful Improvements in Flushing Devices for Closets, of which the following is a specification.

This invention relates to improvements in flushing devices for toilet tanks and particularly to flushing devices for lowdown tanks that are used in connection with closet bowls and the principal object of the invention is to produce a flushingdevice which may be placed in alower portion and be operated without the use ofrubber valves, seats or mercury seals.-

It is also an objectto provide a flushing mechanism with a inimum numberofmovable parts.

It is also an object to provide a flushing mechanism in which air is usedas the seal or valve to prevent operation or flushing of the connectedbowl. 1 A

It is a still further object to have the water in the tank balance the air entrapped to form the seal so that a minimum amount of effort is required to initiate the flushing operations with corresponding diminution f the-noise incident thereto. I

It is a still further object to provide a flushing mechanism with means to quickly start'the siphon into the discharge pipe, thus diminishing the noise of operation. I

In the accompanying drawing, forming a part of this specification: Figure 1 is a vertical sectional view taken through a flush tank constructed in accordance with the present invention and through a closet bowl connected therewith, the bowl being turned through an angle to more clearly show the flush tank and its connection to the bowl. Fig. 2 is a similar section, the'bowl being also turned at an angle and showing the unsealed position. Fig. 8 is a section of the bells and headof the 'dischargepipe on a larger scale to more clearly show the con tracting of the bells when the tank'is full of water ready for flushing. Fig. 4: is aplan view of the discharge pipe with the apron partly broken away.

' Heretofore in the operation,.especially of low down toilets, rubber valves or seats have been used which soon harden'a-nd perunit leakage, and this type of valve is readmercury seals are used to overcome these defects, the expense of maintainance is materially increased. My invention overcomes these defects, uses air as a seal, and accomplishes the result with members impossible to displace under ordinary conditions and with no expense for maintenancetogether with a decrease in the objectionable noise when in flushing operation. I

The details and features of the invention will now be more particularly described, reference being had to the said drawing in which 5 indicates a flushing tank adapted to be mounted upon a wall or otherwise suitably supported a slight distance above the bowl 6 of a toilet closet. The flush may be of any. ordinary construction and a flush or discharge pipe. 7 extends downwardly therefrom so as to act with the trap 8 pref erably built in'the closet-bowl. The parts are usually arranged so that the pipe 7 is in 7 vertical position and extends into the long leg 'Of the water trap 8. The upper end ofthe pipe7 projects upward about half way into the tank 5, and its upper end is formed with a flaring portion 9 having projections 10 upon its upper edge at three or more points. V

- To aid in the discharge of the water and prevent noise the flaring portion 9 is also provided with a downwardly inclined apron 11, the waterleaving the lower edge 12 of this apron, is distributed over the cross section of the discharge pipe 7, forming a plug of water which in falling :creates a vacuum and starts the siphon. In the ordinary construction of discharge pipes, the water initially runs down the inside of the pipe 7 leaving an air filled center and making much noise. A bell l-lrests at all times upon the upper ends of' said projections 10 as clearly shown in the drawings, and the said bell 1a is made of considerable depth or about equal to the height of the discharge pipes, and its lower edge projects downcentral opening to receive said tube while the lower end of the tube extends down Cooperating with the bell 14 1s tral portionwill rest upon. the lower bell 14: and close the upper open end of the tube 16 and leavin an annular air s ace 18' between the bells.

The bell 14 is provided with an eye 19 having an extension 21 looselyv fitting into the tube'16 and serving as a guide, but having sufficient clearance so that air may pass out of the pipe 16'when the bell 17 is raised. Bell 17 is provided with an eye 19 by which it is connected to the link. forming a member of a link mechanism leading to a convenient operating lever or button; 7

The tank 5 maybe provided with any suitablevalve28 for controlling the supply of water to the tank, the said valve being automaticallyoperated by a float 29 and a float lever 30; the valve 28 being connected with the service pipe 31 in the 'usual way. An

" after fill 32 may also be provided extending from the valve28 andbeing bent so as to enter the lower bell l l and pass upwardly therein, itsv inner end being turned downwardly within the pipe 7 fora short dis- 1 tancev This pipe will supplyadded water will, after a flushing operation, gradually which may be needed to insure the maintaining of the water in the bowl at a proper height, in the usual and well known manner.

In the operation of the device the water rise in the tank 5 until a proper height has been attained in the tank to shut the valve 28. The bells being contracted, the water will also rise in the lower portions of the bells until the air'entrapped within thepipe 7 and between the bells '14:, and the water in the trap 8 is slightly compressed, and balances the water in the tank 5, the parts are so proportioned that the water will not risev farenough inthe lower bells to overflow into the tube 7.

WVhen it is desired to flush the closet the lever is operated to lift the bell 17 this will release the pressureby allowing the air in the pipe 7 to escapeup through the water in the tank by way ofthe tube 16 and upsets the balance between the saidair and the water in the tank 5 and the :water will rise in the bell 14 and'enter the flush pipe overthe upper edge thereof, the apron 11 distrlbuting the waterto completely fill the pipe and carry the water out with a minimum amount of noise; a slight pressure of about one quarter of a pound above the ordinary atmospheric pressure being main tained in the air seal. The siphonizing-action W111 be continued until the; water. has

an upper hell 1? which is of such shape thatits cenpipe secured therein. a 7 c 3. flushing mechanismf comprising {in .COIIlblIliltlOIl wlth a flush tank and a bowl,

moves turning the lever-30 and opening valve 28 to admit water from the service pipe. As the water gradually fills the fiushing tank again, the water and air will assumethe same relative positions as before the flushing operation. The weight of the bell guided by the rod 30 extending into the pipe 16immediatelyreturns .it to the normal positionclosing thepipe 16 as the siphoning is established. V l,

While the tank is filling water flows through the refill pipe 32 supplying an 7 amount equal to that lost by the inertia of the water flowing out of the bowl during the V flushing operation,

When the water leaves as normal high level thefloat 29 attains a position such that,

it closes valve 23 when the tank is ready for another flushing operation. 7
