Specification of `Letters Patent.

Serial No. 664,494.

To all 'whom it may concern:

Be it known that I, EVERETT P. ALLEN,

a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, `have invente'd a certain new 4and useful Improvement in Siphon-Valves,

vof which the following is a specification.

My invention relates to siphon valves, and

khas for its object to provide a new and improved valve of this description. p y invention is illustrated in the accompanying drawings, wherein- Figure l is a view of the valve; Fig. 2 is a longitudinalsectional view of the valve of Fig. l showing it connected to the radiator.

I have shown my invention .as applied lto a valve adapted to be used in connection withsteam `heating systems. As herein shown t-he valve has an outer casing A. Within said'casing is a valve chamber B containing a iloat valve C. The chamber B is connected by the connecting piece D with the heater. A passageway 'E' leads from the chamber B to the tube vE1, and communicatespwith the atmosphere. Said tube E1 passes .through the chamber F. The chamber B is connected with the chamber F by the connection G. The valve C is a float valve and is operated by means of water or the like, the parts arranged so that when the water reaches a predetermined height t-he valve will be floated so as to move the part C1 so astostop the passageway E.l When the passageway E is open the air from the heater vpasses out there-- through and through the tube E1 to the atmosphere. When the steam passes through the tube E1; itL heats the chamber F and the air thereiinthus forcing the water down into the chamber B so as to float the valve C and close the passageway E. A siphon device' is connected with the valve, said Siphon device consisting of twoparts H and I. The part H is fastened in position in any desired manner, as by solder, and 1s preferably arranged at -the top ofthe connecting piece D, one branch proj ecting. down into the chamber B. If desired, an oifset,

50 as shown at H1, may be made in the chamber B for the end of the part H. The part I is inserted in the heater andthe end thereof projects below theendf of the part H so that a Siphon effect is produced, The

parts H and I are adjustably connected Vtogether so that they may be rotated with relation t0 each other, and so that the bent ends thereof may be spread apart or moved closer together by sliding one telescoping part within the other. These results may be secured inlany desired manner as, for example, by making one of the parts t into the other with la tight fit which will prevent leakage, but which will yet permit rotationand longitudinal movement.

' I have described in detail a particular construction embodying my invention, but it is of course evident that the partsmay be varied in form, construction and arrangement, and I therefore do not limit myself to the particular construction shown.

' The use and operation of myu invention are as follows: In attaching the device vto the heater the part I is first inserted in the opening in the heater adapted to receive y,the

D is then inserted in said opening and the valve is then "rotated so asnto cause the screw.- threaded connecting piece D to be forced into the opening. I During this operation the part I being in the radiator cannot rotate, but because of its connection with the part H the valve and the part H can be rotated. In view of the relative longitudinal .movement of the parts H and I they can slide longitudinally with relation to each other so as to adjust themselves to the conditions of use'. After the device is in position and the system is started up, the air from the radiator passes through the passageway E and tube El,

air. When steam 'passes through the tube El it heats t-he atmosphere in' chamber F and forces the water into chamber B raising the valve to close passageway E. When the radiator is shut or the system shut down the air in the chamber F is producing a partial vacuum, thus drawing up the water from the chamber B into the chamber F and causing the loat valve to lower so as to open the passageway E, thus bringing the parts into proper position to permit the escape of the air when the radiator is then turned on. The parts are arranged so that the valve C will be floated and raised to its proper position before the level of the water in the vchamber B reaches a sufficient height to cause the Siphon to ac t,

cooled and contracts,

connecting piece D. The connecting piece Y and then into the into the radiator. The importance of this siphon arrangement will be seen by considering, for example, the situation where the valve contains such an amount of water that when the chamber F has dra-wn all that it can draw into it there ais still so much water in the chamber B as to cause the valve C to float, thus closing the aperture E. Under these conditions it will be seen that the valve becomes inoperative, for no heat can pass up through the passageway E so as to eX- pand the air in the chamber F and cause itv to force water out. This condition would occur, for example, when the radiator becomes flooded or under other conditions which lill the chamber B while the chamber F is cold. The 'Siphon is so adjusted that when the abnormal conditions are present a sufficient amount ofthe water will be drawnV off to put the valve in operative condition.

It will be noted thatwhen the parts are assembled, the two telescoping parts of the siphon may be moved longitudinally so as to vary the distance between the siphon legs. It will further Ibe noted that each leg is provided with an angular piece and that these two angular pieces between the legs are telescoped, and are free not only to rotate but to move longitudinally.

Y 'I claim:

1. The 'combination with an air valve of a ,Siphon for drawing water from said valve under predetermined conditions, said Siphon passing through the valve inlet and having two relatively movable parts free to move longitudinally when the parts are assembled so as 'to vary the distance between the legs of the Siphon.

2. The combination withy a valve for heating systems of an adjustable Siphon passing through the valve inlet adapted to ldraw water from the valve under predeter'mined'conditions and comprising two telescoping parts between the legs of the Siphon, so that they may be spread apart without`disconnecting them.

3. The combination with a valve of a silpredetermined conditions,

phon passing through the valve inlet adapt# ed to draw water therefrom under predeter- 'i mined conditions, lsaid Siphon comprising two parts adjustably connected together when the parts are assembled in their operative relation so that the may be rotated or moved longitudinallywith relation to each other.

4. A valve for steam heating systems comprising a. chamber, a fioat valve therein, a

passageway controlled by said float valve,

means for introducing liquid into said chamber under predetermined conditions to fioat the valve, an adjustable Siphon passing through the valve inlet connected with said chamber for drawing oif the Water-under predetermined conditions having two telescoping parts by means of which the legs of the Siphon are adj ust-ably connected together.

5. A valve for steam heating systems comprising a chamber, a ioat valve therein. a passageway controlled by said `float valve, means for introducingv liquid into said chamber under predetermined conditions to float the valve, an adjustable Siphon passing through the valve inlet connected with said chamber for drawing oli' the water under predetermined conditions, said Siphon comprising two parts at an angle to the legs of the Siphon and connecting them, Said parts movably connected together so that LVthey may be rotated and moved longitudinally with relation to each other.

' 6. The-combination with an air valve of a Siphon for drawing water therefrom under predetermined conditions, said Siphon passingthrough the valve inlet and Ahaving two le s anggl'e thereto, said latter parts working the one within the other, so that the distance between the legs may be varied.

7. The combination with an air valve of a siphon for drawing water therefrom under said siphon conlsisting of two pipes bent at right angles and telescopically joined together, said Siphon passing throughthe Valve inlet.
