THERMOSTATIC-CONTROLLED VALVE.
Application led January 25, 1927. Serial No. 163,500.
The present invention is directed toimprovements in thermostatic controlled valves.
The primary object of the invention is to provide a device of this character so constructed that should the flame of the pilot burner become extinguished the supply of gas will be instantly cut ofi' from the pilot burner and heater burner.
Another object of the invention is to provide a device of this kind which will be extremely simple in construction and sensitlve in operation, and one which will quickly and positively operate to open or close the fluid flow controlling valve.
In the accompanying drawings:
Figure 1 is a vertical sectional view through the valve, showing the valve stems in its elevated position to permit gas to flow freelyto the burner.
Figure 2 is a sectional view on line 2-2 of Figure 1.
Figure 3 is a side View of the valve showing the modified form of the invention.
Figure 4 is a sectional view online 4-4 of Figure 3.
Referring to the drawings, 1 designates a vertically disposed casing in which are formed vertically spaced webs 2 and 3,'provided, respectively, with valve seats 4 and 5, said casing having branches ti and 7I con-v nected therewith. A gas inlet or supply pipe 8 is connected with the branch 6, while to the branch 7 'is connected a pipe 9 which supplies the fuel to the burner or burners, not shown.
The upper end of the casing is provided with a stuffing box 10 having mounted thereon anti-friction roller bearings 11 which engage the stem 12, said stem being slidable in the box 10 and has adjustably mounted thereon valves 13 and 14 which coact, respectively, with the seats 2 and 3. The lower end of the stem engages the upper end of the spring 15 mounted upon the bottom of the casing and below the valve seat 3, said spring serving to normally hold the stem elevated and the valves unseated in order that gas can flow freely through the casing as long as the burner is in operation. The upper end of the stem 12 is provided with an enlargement 16 having a transverse groove 17 formedtherein, the .purpose of which will be later explained.-
Mountedv upon the top of the casing is a frame 18, the to bar 19 of which is provided with a threade opening 20 and in which isA -threaded for Iadjustment the stem y21, said stem having an enlargement 22 formed upon its lower endand is provided with a trans-v verse groove 23 which confronts the groove 17 of the enlargement 16, said grooves when confronting providing a guide 24 for cooperati on with the head 25, said head having oppositely disposed taperedends 26 and 27 Leading from the casing 1 at a point below the valve seat 5 is a. horizontally disposed pipe 28, the outer end of which has fixed thereto the lower end of the pipe 29, the orifices 30 in its upper end constituting a pilot burner. The pipe 28 is provided with a valve 31 which, when open, permits gas to flow through the seat 5 to pass there-through to the pilot burner.
Adjustably mounted upon the pipe 21 is a thermostatic bar 32,the upper end of which is pivotally connected to the outer end of the rod 33, the inner endof saidI rod being fixed to the head 25.
.As shown in Figure 1, the end 27 of the head 25 is in a position to prevent the stem l2 from moving upwardly under the action of the spring 15 and at which time the valves 13 and 14 are unseated, thereby permitting gas to freely flow through the seats to the burner.
As long as the pilot burner is burning, the heat therefrom will maintain the bar 32 in the full line position, as shown in Figure 1. However, if the pilot is extinguished the bar 32 will contract' and move to the position shown in dotted lines in Figure 1, thereby drawing the rod 33 inwardly, thus causing the tapered end 27 to move inwardly in the guide 24 formed by the opposed grooves 17 and 23, which actionV forces the stem 12 downwardly and causes the valves 13 and 14 to seat and close the passages of the seats 4 and 5, thus -shutting off the supply of gas to the burner or burners. It will be observed that when the valves 13 and 14 are seated that the spring 15 is compressed, and will remain thus as long as the pilot burner is extinguished. Upon lighting the pilot burner, the bar 32 will expand and move the head 25 forwardly, ths permitting the valves to unseat in an obvious manner.
While I have illustrate-d the valves 13 and 14 in the preferred form of the invention as seating upon the upper surfaces of t accomplish this it is only necessary that the tapered end 26 of the head 25 enter the guide 24 from the inner end which can be readily accomplished by shortening the bar 33. n i' In the modified form of the invention as shown in Figures 3 and 4, a bracket 34 is mounted upon the casing 35 and pivotally supports the u per end of the link 36, the lower end of which is pivotally connected to the upper end of the link 37 by a pin 38. The lower end ofthe link 37 -is pivoted to the upper end of the valve stem 39 which functions .in the same manner as the stem 12, of the preferred form of the invention.
The rod 40 has its outer end pivoted to the pin 38, While the outer end thereof is similarly connected to the thermostaticbar '4l mounted in a manner similar to that of gushed, the bar 40 will move to the position shown n dotted lines in Figure 3, thus breaking the links and permitting' the spring 44 to move the stem 39 upwardly closing the valves 42 and 43, thus cutting off the supply of gas to the burner or burners.
For the sake of clearness I have not deemed it necessary to illustrate the location of the valves with respect to a heater, since it will be of course understood that the same can be connected thereto at any convenient point and in any convenient manner.
Having thus described the invention, I claim: A y
1.- The combination with a valve casing having a seat, a stem slidable in the casing and having a valve for cooperation with the seat, the upper end of 'the stem having an enlargement thereon, a second enlargement st-ationarily mounted in alinement with the stein, ahead movable between said enlargements and capable of forcing the valve stem vsupported by the casing, an enlargement adjustably supported by the frame, a second enlargement carried by the valve stem and alined with the rst named enlargement, a headymovable between the enlargements and thermostatic means for sliding the head in a direction to force the second enlargement downwardly to seat the valves against the influence of the resilient means to cut off the supply of gaseous fuel to the heaterk burner and pilot burner, said resilient means unseating the valves when the head is slid in a reverse direction.

In testimony whereof I ax my signature.
