Patented Mar. 31, 1936 UNITED STAES GAS COCK Thomas H. Roberts, Detroit, Mich, assignor to Roberts Brass Man ufacturin'g Company, De-

trolt, Mich, a corporation of Michigan Application April 18,1932, Serial No. 606,027 9 Claims. (Cl. 251164) This invention relates generally to valves and refers more particularly to gas valves of the rotary plug type designed for use in connection with double burners in ovens and the like.

45 Referring now to the drawings, A is the casing; B is the cap; C is the rotary plug; and D is the handle stem of a valve embodying my invention. As shown, the casing A is a casting having a central portion l and the laterally pro- 5 jecting L-shaped portions 2 and 3 respectively. Preferably the central portion I is provided with a tapered socket 4 and a transversely extending inlet passage 5, while the wing portions 2 and 3 are provided at their free ends with threaded 55 sockets 6 and 1 respectively and are provided Figure 8 but showing the position of the plug when the pas:

with outlet passages 8 and 9 respectively that extend from diametrically opposite sides of the socket 4' to the inner ends of the sockets 6 and I. Preferably the central portion I of the casing isprovided at the open end of and around approx- 5 imately half the socket 4 with an arcuate recess l0 and isprovided in said end at substantially diametrically opposite points of the socket with threaded sockets II and I2 respectively.

The cap B is preferably formed of sheet metal 10 and has a cup-shaped portion l3 registering with the open end of the socket 4 and is provided at diametrically opposite points of said cup-shaped portion with laterally projecting attaching flanges l4 and I5 respectively which are secured 15 I to the central portion l of thecasting by screws l6 and I1 respectively engaging the sockets II and I2. Preferably the cup-shaped portion l3 has a central opening l8, an annular flange or shoulder l9 concentric with the opening, and radially extending slots 20 and 2| respectively at approximately diametrically opposite 'sides of the opening. o

The rotary plugf'C fits in the socket 4 and is provided in its outer end with a substantially cylindrical socket 22. As shown the plug terminates flush with the outer end of the socket 4 and is provided intermediate its ends with three --passages 23, 24 and 25 respectively that extend transversely thereof in a common horizontal plane and meet at the center. Preferably passages 23 and 25 are in alignment, while the passage 29 is disposed at substantially right angles to the passages 23 and 25.

'The handle stem D has a cylindrical portion 5 26 in the opening ill in the cap, has an annular flange 21 engaging the inner side 28 of the cap, and has a substantially rectangular portion 29 in the cylindrical socket 22. Preferably the rectangular portion 29 of the stem has a downwardly opening sl bstantially cylindrical socket 30 and is provided at diametrically opposite sides of said socket with transversely extending slots 3| and 32 respectively. A pin 33 extending diametrically across the socket 22 in the plug and into the recess ID in the casing is received in the socket 30 and slots 3| and 32, while a coil spring 34 within the socket 30 abuts the pin 33 and normally holds the flange 21 of the stern against the inner face 28 of the cap. A washer 35 is non-rotatably sleeved upon the rectangular portion 29 of the stem andhas laterally projecting lugs 36 and 3'! respectively'that are engageable with the slots 29 and 2| in the cap, and a coil spring 38 is sleeved upon the rectangular portion 29 of the stem between the upper end of the plug C and the washer 35 and normally holds the lugs 36 and, 31 of the washer against the flange IQ of the cap.-

Inuse when the parts are in the position illustrated in Figures 9 and 10, the valve is fully closed. In this position the pin 33 is substantially midway between the ends 40 and 4| respectively of the arcuate slot ID in the casing and the lugs 36 and 31 are in the slots 20 and 2|. Thus the plug is locked against axial rotation. Should it be desired to have gas flow through the outlet 8, the handle stem D the flange 21 will move the washer .35 downwardly and cause the lugs 36 and 31 to be. removed from the slots 20 and2| whereupon the plug C may be turned by the stem D to cause the passage 23 to register with the inlet 5. (Figures 7 and 8.) When in this position the pin 33 will abut the end 40 of the recess I and the lugs 36 and 31 of the washer will be held by the spring 38 against the flange l9 oi'the cap. Upon turning the plug C from the position illustrated in Figures '1 and 8 to the position illustrated in Figures 9 and 10 the lugs 36 and 31 will slide on the flange 9 until they are in vertical alignment with the slots and 2| whereupon they will be moved upwardly in said slots by the spring 38 and the plug C will again be locked in closed position against axial turning movement. Should it be desired to have gas flow through the outlet 9, the handle stem D may be depressed so that the flange 21 will move the washer 35 downwardly and cause the lugs 36 and 31 to be removed from the slots 20 and 2| whereupon the plug C may be turned by the stem D to cause'the passage to register'with the inlet 5. (Figures 11 and 12.) When in this position the pin 33 will abut the end 4| oi the recess l0 and the lugs 36 and 31 of the washer 35 will be held by the spring 38 against the flange IQ of the cap. Upon turning the plug C from the position illustrated in Figures 11 and 12 to the position illustrated in Figures 9 and 10, the lugs 36 and 31 will slide on the flange l9 until they are in vertical alignment with the slots 20 and 2| whereupon they will be moved upwardly in said slots by the spring 38 and theplug C will again be locked in closed position. I! desired the plug .0 may be turned from the open position illustrated in Figures 11 and 12 to the open position illustrated in Figures 7 and 8 or vice versawithout being locked in the intermediate closed position illustrated in Figures 9 and 10 by pressing the handle stem D inwardly against the tension of spring 34 while it is being turned so that the lugs 36 and 31 of the washer will pass beneath and behind the slots 20 and 2|.

Thus from the foregoing it will be apparent that I have provided a safety gas valve wherein the plug C will be locked automatically in the closed position illustrated in Figures 9 and 10 when the handle stem D is operated normally, 1. e., merely turned without being moved longitudinally, but that may be moved from one open positionto the other without being locked when the handle stem D is operated abnormally, i. e., pressed-inwardly while it is turned. Regardless of how the stem D is turned, i. e., merely turned or held inwardly while being turned, the outlet passage 8 is closed before the outlet passage 9 is opened and vice versa, therefore, only one outlet is open at any one time. When the plug C is in the closed position illustrated in Figures 9 and 10 the'handle stem D must be pressed inwardly to release the lugs 36 and 31 from the may be depressed so that.

slots 20 and 2| when it is desired to turn the plug to either of the two open positions aforesaid. Thus the valve can not he accidentally opened. Both springs 34 and 38 retain the plug C in the socket. The spring 34 urges the handle stem D outwardly, while the spring 38 urges the washer 35 against the cap. The pin 33 serves as an abutment or seat for the spring 34 as well as a. stop for theplug C, consequently an extremely practical and efiicient construction is provided.
