Application tiled March 14,1927, Serial No. 175,351, and in Cuba March 1, 1927. i

This invention refers't'o a siphoiiicflushu ing device used for the discharging lof receptacles, and especially referring to. such a device used to' operate the` discharge ofwatercloset tanks; and) has for its main obj-ect the providingoi' adevice adaptable tanksof thisvkin'd, and also`l toy anyr other kind-oftank or receptacle, which-device opcrates pneumatically, and prevents all kind of" wear, andA also*l all possibility of obstruction in lilling `or discharging of the V,tank or rece tacle.

` `.llt t e same time the usey of this device "prevents the overlowingjofl the tank, due to `imperfect conditionof the inlet cocks or of the` lioaters, because before this can' occur, acomplete discharge ofthe tank' will have 'taken place.

, in the course of* this specification, especially those'persons- `skilled inthe art to which tank provided witl'rafsiphonic `flushing device according to this invention, l showing an operative position.Y

Fig. 2 is a vertical diametrical sectionin y d'etailandn ony enlarged scale, of the@ device. Fig. isl a horizontal` section on lines i 3-3of Fig. 2.

Figfl is a sideelevation, partially cut,`

of the device.

In Fig; 1 shown a tank 1 such as used in water closets, andin thebottom ofiwhichv is an opening 1,"`on` whichis screwed a branch ofthe discharge pipe 2 by means of' a" packing, comprised ofa nut 3 and a washer or packing ring 4, lplaced between an annular flange 2 integral' with the pipe 2 .andthe bottom of theY tank l. In the lower endof the pipe 2 which projects out from "the, tank is'screwed the branch of the discharge `ipe which lead'sto the` bowl of the water c oset, which is" not shown. p

`A115 is designated a cylindrical'casing apen` at' the top, and which 'has in its` botthrough which passes the tom 5, an o enin p iepipe 2 whichv yprojects upper part4 of t Withinv the tank 1 and isfastened to the same by afnut 6 screwed" 4tofthe pipe 2 and `regards to bottom of the tankl Mioreadvantages and other considerations pertaining to this invention will be deduced abuts against the liange 2 so that the bottoniofsaid casing 5 is spaced slightly with Figures 1 and 2?). i

Covering` the upper part of the pipe 2K is acoverf( in shape oi' a bell, resting on the bottom of the casing 5 and leaving with respect to the wall or the saine an annular chamber 8. The bell 7 presents'in its lower part a plurality of spaced openings` -7y to permit the passage oi' the liquid to the space? 9I between the pipe 2 and the bell 7.

Around the*` receptacle 5 isp'laced a second bell shaped cover, 10, whichA has its mouth slightly narrowedV and rests uponia peripheral edgev 5 which constitutes an in` tegral extension with the bottom oi. the annular chamber 11. In the lower part ofthe bell l0 there are a serie-s of spaced openings 12 and yfrom this lower part, over the lines of openings 12 extends a flange 10 which is" prolonged lower than the edge 5" for the purpose which will be explained hereinafter and leaving a space or annular chamber 13 with respect to the body ofthe bell 10'.A

' At the `top of the bell lO'is ,fastenedfan' eye bolt 14, and to it issecured cable 15 which at its.I otherend is fastened to the leverl or arin 16I usual in` tanksof this kind, and which is Aoperable by' -a chain 17,*although this last 'arrangement may," be changed, and anyother forni ofconnection may be vused with 4the belll` 10, so as to be suitable to the `kind of tank to which the device is applied The working` of the `device is asv explained in the following:

Assuming the parts placed in theposition shown in Fig. 2, that is, the 'bell 1() resting upon the edge 5f ofthe receptacle 5. The levelof the water ,inv the tankis suitably determined by a float or other means at such a point aboverthe bell 10 so that the water which flows through the openings 12 will illthe chamber l1 not higher than` the upper edge of the casing 5, the air,V pressure existing in the space between the bells and 10, preventing the overiow to the chamber 8. Thewater contained `in the space 9'will remain at a level with the upper'edzge'of `said ipe 2 and the` water containedinthe' is raised as shown in Figure 1, then as the space between the bells 7 and 1() becomes greater, the air pressure between the same will be diminished, and the Water which is in the chamber 11 will overllow into the tank 8 establishing a siphon draft toward the pipe 2 through the openings 7 and discharging the Water through the pipe E2, to the bowl, as shown by the arrows, in Figures l and 2.

In the meantime, upon discontinuing the pull on the chain 17, the bell 10 will again rest upon the edge 5 and the discharge Will continue, the Water which is in the tank 1 flowing through the openings l2, under the` lange 10 which extending downwardly belovv the edge 5 approximately to the bottom of the tank 1, will cause all the Water contained in the tankil to be discharged through the pipe 2.

'When the discharge is completed, there will remain only a Ismall quantity of Water in the chambers 9 and 11 the level of which Will be dillerent, due to the diiference in pressures existing under the bells and 10, as may be seen in Figure 2. The Water which continues to flow through the openings 12, coming from the inlet pipe to the tank can only reach a level in the chamber 11 lower than the edge ot the receptacle 5, due t0 the air pressure existing in the chamber 10.

It is evident that Within the principles ol construction before explained, many changes may be made, Without departing from the substantial ideasot this invention, so that I do not limit myself to that which has been described, but Wish that the Letters Patent protect that which is consigned Within the scope of the following.
