Application filed This invention relates t useful improvements in N, 01 MILWAUKEE, WISCONSIN, ASSIGNOBS, STAT CORPORATION, OF MILWAUKEE, WIS- HEATEB APPLIANCE.

o certain new and heater appliances and, while the same refers more particularly to that type of heater generally employed for supplying hot water to a household, it

may be applied to any type of heater utilizing a fuel burner.

and the dangers incidental thereto, in that should the pilot light become.

Hence this invention has for one of its objects to provide a device of the class described in which incapable fuel su ply as long as tinguis ed.

Another object of this invention is to provide a device 0 the character described which is capable of actuation either at the heater or at some point remote therefrom.

A further object provide a device of of this invention is to the character described which is so designed and constructed as to be capable use by the drilling of casing .wall thereof adjacen burner fuel valve, whereby cost of connecting the our improved but of-application to heaters now in one hole in the t the burner and supply through stallation is reduced to a minimum and the f the a skilled mechanic eliminated. A still further object of this invention is class described January 16, 1922, Serial No. 529,782. Renewed October 27, 1926,

which is capable of operation for a predetermined time at the end of which the burner fuel supply is automatically disconnected.

A still further object of this invention resides in the provision of a device of the character described in which a thermostatically controlled valve prevents the retaining in open position of the burner fuel supply valve in the event the pilot light should be extinguished.

With the above and other objects in view which will appear as the description pro cecds, our invention resides in the novel con struction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the hercind sclosed invention may be made as come within the scope of the claims. In the accompanying drawings, we have llustrated one complete example of the physical embodiment of our invention constructed accordin to the best mode we have so far devised or the practical application of the principles thereof, and in which:

Referring now more particularly to the drawings, 5 designates the casing o a water heating appliance which may be of conventional construction having, a water coil 6 and a burner 7 so arranged that its flames play on the coil, the burner bein connected with a fuel supply line 8 by a ipe 9 which leads through our improved va ve construction 10, to be later described.

Cap 35 is provided with a cylinder 37 concentric with casing 33, the space between cylinder 37 and casing 33 being connected by a plurality of passages 38 which terminate in a well 39 in the bottom of cap 35, said well forming a seat for a ball valve 40 which prevents passage of fluid from the interior of cylinder 37 through passages 38 but permits fluid to flow into the cylinder through said passages.

outwardly throu h a stufiing box or land 43 and has a hem? 44 secured thereon. cad 41 is normally urged inwardly by a spring 45, coiled about stem 42 and confined between cap 34 and the piston head, and has a snug or slidin fit in the bore of the cylinder, the base of 51s cylinder being counter-bored, as at 46, for a slight distance to permit free movement of the piston. The interior of casing 33 and cylinder 37 is filled with an oil or other suita le fluid so that a movement upwardly of piston 41, against the action of spring 45, W11 lpermit the fluid to follow the piston and w en the piston is released spring 45 will tend to return same to normalposition, valve 40 reventingthe escape of fluid from behind t e piston.

To insure the slow, steady return of the piston under action of s ring 45, a b pass 47 is provided between t e interior 0 c linder 37 and the space between the cylinder and casing 33-wh1ch may be adjusted by a set screw 48 The-greater the: distance piston 41 1s moved away from the inner end of the cylinder, the longer the time required for its return to normal position and when piston 41 reaches the counter-bored portion 46 of the cylinder the same rapidly descends under action of 's ring 45.

Ifer manipulating piston 41, a sliding rod 9 is mounted in apertures formed in lugs or ears 50 of the bracket member 36 which is connected with head 44 by a stem 51, red 49 having a handle 52. In operation handle is raised resulting in connectin head 44 with the end of stem 21 and moving valve 20 away from its seat. As the iston 41 slowly descends, valve 20 is move toward closed position and as the valve nears its seat, piston 41 enters counter-bored portion 46 and is thus permitted to descend rapidly tation of the shaft '0 and seat valve 21 with a snap to eliminate the slow extinguishing of the burner 7 and the dangers incidental to escapage of gas which would necessarily result from such an operation. As will be readily obvious, bracket-member 36 may be graduated, as illustrated in Figure 1, in order that the operator may move handle 52 to any designation in order that the time during which the burner 7 remains lit may be readily re ulated.

n order to eliminate any danger of the fuel supply being connected with burner 7, should pilot 26 be extinguished, and thus permit the escapage of unburnt gases, a thermostatic controlled valve 53 is provided wh ch permits the liquid behind piston 41 to pass through a passage 54 into a tube 55 should the pilot light be extinguished and thus cause the piston to rapidly descend under action of spring 45, should it be raised by handle 52 or the remote control device to be hereinafter described. 1

. Tube 55 is formed of brass, or any other material having a relatively high coefliclerit of expansion under temperature changes, and extends upwardly through an opening in casting 25 and has its upper portion en- 'closed by a cylinder or casing 56 which is closed at its upper end and provided with suitable vent o enings. The upper end of tube 55 is close b acap 57 to which is adjustably secured t e upper end 58 of a rod 59 of steel, or an other metal having a relatively low coe cient of expansion under temperature changes, and which extends throughout the entire length of tube 55 and has valve 53 secured to its lower end.

Valve 53, as best shown in Figure 2, normally seats against the peripheral walls of a port 60 which separates bypass 54 from the interior of tube 55 and is held against its seat as long as a flame is burning at pilot jet 26 and tube 55 is expanded. Should the pilot be extinguished, tube 55 cools and consequently contracts moving valve 53 from its seat and communicating tube 55 with the lower end of cylinder 37, as before described.

Should the appliance be located in the basement or at some other remote point, a cable 61 has one end connected with rod 49 and its other end connected with a crank or drum 62 on a shaft 63 which is rotatably mounted at any convenient point so that a roits handle 64 will raise e device, and in order that the operator may set the device for any desired period, handle 64 is provided with a ointer 65 which is adapted to be brought into alignment with any suitable time designations delineated on a dial 66. i

As the operation of our improved device will be readily obvious from the foregoing description and the accompanying drawings. further discussion is deemed unnecessary.
