CLOSET TANK.

Application filed June 17, 1925.

To all whom t 'may concer/n.'

Be it known that l, Roen'n'ro HcrDarcr-r r MARTINEZ, citizen ot the Republic otl Cuba., residing at Habana, Cuba, have invented certain new and useful Improvements in Closet Tanks, or which the following is a specitication.

This invention refers to closet tanks and especially 'to closet tanks ot the lower type, although said invention can be applied to tanks of the high type with slight modilications without atecting the essential idea` o1" the invention, and has for its main object the providing of a modification in the construction ot tanks ot this kind which avoids joints, packing etc. and makes the discharging of same take place by mechanical means when wished, emptying the tank totally and avoiding leaks or continued loss of water and also the frequent and untimely discharge ot the tank which is caused by detects in the valvular system of same.

More advantages and other considerations pertaining toI this invention will be known in the course ot this specication, especially by those experts in the art to which same pertains and by the aid of the figures in the attached drawings in which the same character et reference designate the same parts.

In the drawings:

Figure 1 is an upper plan view of a closet and closet tank constructed in accordance with this invention.

Figure 2 is a longitudinal vertical section according to lines 2-2 of Figure 1.

Figure 3 is a partial sectional view in detail of the tank showing by dotted lines a working position of the parts.

Figures 4 and 5 are detailed views, partial and in perspective of the cooperating parts of the tank.

In the drawings is shown by #1, a closet tank of any approved construction, which rearwardly presents an opening 2 into which projects the upper end of the shortest branch 3 of a trap the longest branch l of which is connected at its upper end to a pipe 5 connected to a bored opening in the bottom ot the tank 6. A

r1`he pipe 5 in its upper end is connected to a device as is shown in detail in Fig. 4L

' of the drawings and consists of a funnel 7 which terminates lowerly in a threaded neck 8 to be screwed to the upper end ot the pipe V and screwed outerly on this neck to the tank o is a washer 9 which cooperates with Serial No. 37,829.

a plate 9 integral with the funnel forming a water tight seal.

From the plate 9 extend in diametrically opposite directions, an arm 10 ending in an enlargement with an eyelet 10 and a supporting member 11 which ends in a seating plate 11. On the end of the arm 10 is pivoted a semi-spherical bell 12 provided for this purpose with hanging ears 12 which presents bores 12 registering with the bore 10 through which is passed a pin 13, and the bell 12 bearing upon the plate 11 in the closing position shown in Fig. 2, and having near its edges a plurality of spaced bores 111, the object of which will be eX- plained further along.

From the body of the bell 12, projects outwardly two ears 12 between which is pivoted the lower end of a rod 15 and connected on its upper end is an angular lever 16 mounted through a. hub 17 which passes through the front wall of the tank 6 and said lever ending outerly in a handle 18 for operating same.

Numeral 19 designates the pipe through which the waterl flows into the tank 6.

The operation ci this tank is as explained below.

Supposing the tank 6 to be lled with water and the bell 12 bearing upon the support 11 of the part 11 and the trap 3--4 lilled, that is with its branches 3 and 4 lilled with water, all as shown in Figures 2 and 3.

Under these conditions the air into the bell 12 and filling the pipe 5 will form a pneumatic closing, preventing the water contailnpd in the tank from entering the funne But if the handle 18 is operated causing the rod 15 to be pushed upwardly, this will drag the bell 12 along and raising same as indicated by dotted lines in Fig. 3, the water will llow into the funnel 7 and form a continuous current in the trap 3 4 discharging into the tank 1 through the opening 2 and which current will continue even when the bell is allowed to drop, when ceasing to operate the handle 18, and discharging all the water contained in the tank 6.

While the tank is being refilled, the water when descending under the bores 14 in the bell 12 will leave them uncovered and ot' course, the vacuum under the bell will be broken and the bell will till with air. The bores 14; will be hydraulically closed when the level of the Water which flows through pipe lQViHtO-vthetank rises, causing the`- pneumatic closure Whcliepirevents. thewater which 'fills the tanl; from owing into the funnel'.

Having thus fully described. the invention, what is claimed is:

A flush tank mechanism comprising in combination with a tank, a pipe extending upwardly in and terminating sli-'gl'it'ly above, the bottom of the tank and having au eX- pandfi-ng open upper end', a hinged plain hemispherical bell for covering the open upper end ofthe pipe;- and means7 arranged within the; tank` and operable fromoutside the tank, toI raise the bellen its hinge, a series` of perfoiiat'ons in the belli and' above the lower edge thereof, a support integral with and, projecting from. the pipe, ears on the support for li'ngedly receiving the bell, and a.,- shelf on the support to receive the edge of the bell when it is in its lowered position and' screw threads on the pipe for connecting it to the tank.

In testimony whereof I have signed my name to this specification.
