AUTOMATIC" VALVE conrnon Application filed June 5, 1924, Serial My invention relates to improvements in automatic valve control mechanism, and more particularly has reference to and is illustrated in the accompanying drawings in its application to means in combination with a valve such as a gas valve for automat-ically operating the sameand cutting off the supply of gas upon the happening of a predetermined event such as an unduerise of temperature.

In said drawings, I have illustrated 1n Fig. 1 in side elevation a suitable form of valve and automatic control mechanism therefor, embodying an application of my invention. Fig. 2 is a perspective detail of one of the operating-parts. Fig. 3 is a similar view of another operating part; Fig. l is a front elevation of the device, the position of certain parts, after the valve has been operated, being shown in dot-ted outline, and

Fig. 5 is a detail partly in section illustrating the construction of the valve closure.

6 indicates a suitable form of boxor outer casing having a suitable hook or ring at the 2 top such as 7 from which may be suspended a link or chain such as 8. 9 indicates a similar link suitably secured to the linlr 8 by suitable means such as solder or fusible material adapted to melt or fuse and allow 36 the links to separate where joined, as indicated at 10. The lower link preferably passes through a hook or hole such as 11 secured to or formed witha weighted member such as 12 which in turn is mounted upon the shaft 13 and is free to rotate thereupon, said shaft .at the right,- looking at Fig. 1, being rectangular in cross-section upon which is mounted the weighted memher or counterweight 14 of less weight than to the weighted member-12 and which is retained thereon by any suitable means such as the cotter pin 15. 16 indicates an offset or lug projecting laterally from the counterweight 14 in the path of movement of the shank or stem 17 of the weighted member 12, so that when the weighted member 12 is released by the fusing and separating of the links'8, 9, the same in dropping brings the stem 17 across'the, path of the lug 16,

i so thereby throwing the'counterweight 14 upwardly and leftwardly looking at Fig. 4 past its dead centre positionuntil it drops in the position indicated in dotted outline by reference character 14. This counterweight having a rectangular hole for pas- No. 718,165. Renewed A rn 2a, 1926.

the carrier or arm 18 shown to better ad- Y vantage in Fig. 3, and terminates at the left end in a reduced rounded portion which has its bearing in the casing of the valve as indicated at 19. This arm 18 is drilled and tapped at 51 to provideengagement for the bolt 20 which is screwed upwardly therethrough looking at Fig. 4; and is provided with a flock-nut 21 to secure it in proper position in the arm 18., The lower end of. the bolt 20 is provided with a suitable head. 22 and the bolt having been first passed through the closure 23 of :the valve, retains the same as shown, the 'hole through the closure 23 and through which the bolt passes 1 being slightly larger than the diameter of said bolt to allow fora little play. Said closure member 23 alsoibored larger, in w the direction of the lower orrounded side thereof, and is provided with a threaded plug 24, as shown. 25 indicates a suitable washer which may be introduced between the head 22 of the bolt and threaded plug 24; to allow aseating for said'bolt, from all of which it will be seen that as the arm-18 moves downwardly anti-clockwise when the weight 12 is released, it carries with it the closure 23 which also shifts anti-clockwise until in the position shown in dotted outline as indicated at 23, thereby shutting off the gas, water, or other medium to be controlled. looking at Fig. 4 through the inlet 26 and passes through the valve, escaping by the outlet 27. The passage 28 through the valve it willbe observed is slightly tapered so as Such medium enters leftwardly to provide a seating as indicated at 29 for f one end of a rope or wire cable 36 is secured as indicated at 37, the same passlng around in the groove of the sheave, the free end passing through the outlet 38 as shown in; Fig. 4. As a further means of support for the case or frame 33 of the sheave, a yoke or U-shaped strap such as 39 is provided with a round hole as indicated at 40 forthe passage of the shaft 13, the inner ends-being secured by screws 41, 42 to the casing 33.

The said sheave or grooved pulley is also" provided with a projection or finger such as 43 which upon the rotation of the pulley moves in the path ofthe cut-away portion of themember 46', shown to advantage in Fig. 2. -:This member is so adjusted upon the rectangular portion of the shaft 13 that when the cable '36 is pulled and the projection 43 encounters the

face

44 or 45 of the member 46, it rotates the shaft 13 the same i valve is adjusted for operating upon a horizontal or transverse conduitor piping, but of course it will be readily understood that by shifting the mounting of parts, such as the arml8 and member 46, ninety degrees, the valve will operate upon a vertical line of pipe, and the same of course applies to theweights 12 and 14. j

Of course it will be understood that various modifications may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.
