This invention relates to certain newV and useful improvements in a safety gas cock and has for its primary object to provide a gas cock or valve construction embodying main and auxiliary lvalves with the auxiliary valve being unaffected or remaining in closed position upon opening movement of the main valve with manually and theremostatically operating devices associated with the auxiliary valve to provide for manual Lopening thereof and thermostatic closing should a flame be accidentally extinguished to prevent loss of life, resulting from asphyxiation.
With the above and otherobjects in view that will become apparent as the natureof the inzvention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.
In the drawingz- 2.0.' Figure 1 is a top plan View, partly in section of a safety gas cock and automatic gas burner constructed in accordance with the present invention;
Figure 2 is a vertical longitudinal sectional View f l1showing the tensioned auxiliary valve in'closed position with the manually and thermostatically operated devices associated therewith;
Figure 3 is a bottom View -of the gas cock and` thermostatic device.
" Referring more in detail to the accompanying drawing, the reference numeral 1 designates a valve body or casing having an Vaxial bore therethrough for the flow of gas with a transverse opening to receive the tapered valve 2 having a -1transverse -port 2a adapted to be broughtinto and out of registrationwith the bore of the cas-V ing. The head 2b of the valve is provided with an arrow indication 9 to designate the position of the transverse port k2a relative to the bore 4010i the valve casing. One end ofthe valve casing 1 is provided with a valve seat 1b to be engaged'Y by a ball valve 4 that is moved onto its seat by the coil spring 5 which spring is retained in position in the bore by the cross pin 7 as shown in Figure 2.
the plate 3 and rod 14 provides for lost motion of the rod to permit additional movement of the rod and thermostatic element without interference'from the plate 3.
When the valve stem 2 isin its closed position 75 with the transverse port 2a extending transverse-y ly of the passage through the valve casing, the attened sides of the projecting end ofthe valve stem project longitudinally of the valve casing,
while the lug 2d is engaged with the nger piece 80 z 10 for the projectionof the plate 3 so that the angle finger. 2e on the end thereof is disposed relative to the slot 15 in the rod 14 to permit4 the spring 5 to move the ball valve 4 upon its'l seat 1b, this Vposition being shown in Figure `2. 85V.
It is impossible to move `the sliding plate 3 for unseating the ball valve 4 when the valve stem 2 is in its closed position. Upon opening the valve stem 2.to align the transverse port 2a. there of with the gas passage through the valve casing, the lug 2d upon the valve stem is displaced relative to the nger piece 10 while the ball valve 4 still remains upon its seat. Upon moving the plate 3, by the finger piece 10, the angle nger 2e valve '4 to unseat the same against'the tension; of the kspring 5, and theplate 3 is so held duringy ignition of the burner and for aperiod of time to permit the thermostatic element to assume the flexed position, and at which time'the plate is shifted to place the nger 2e in the opposite end of the slot 15 in the'rod 14. The auxiliary valve 4is maintained in its open position by the thermostatic element while the burner is in use,V but f should the ame become accidentally extin guished, the thermostatic element will assume a normal position and permit shifting movement Y of the rod 14 relative to the ball valve; being ung hindered by the Vplate 3, toA permit the'ball valve to be closedron its seat by the spring 5,."
While there is herein shown and described the preferred embodiment of the present invention,`
it is nevertheless'to be understoodthat minor changes may be made therein without departing Y and scope of the invention as of its ends by said thermostatic elementwith YtheY other end thereof positioned for engagement with the tensioned auxiliary valve, and a lostY motion connection between the plate and rod to allow`` additional expansion of the thermostatic element Without affecting. movementofthe-plate.; Q
2. In a thermostatic cut-01T for gas burners, the combination with a valvestructure embodying'a manually operable main valve and an auxiliary Vvalve-tensioned in the direction of closing movement, of a plate slidably mounted on the valverstructure and retained thereonrby the main valve, a thermostatic element responsive to Yheatofthe burner,` a slidelrod positioned for operation at one of lits ends by said thermostatic element with the other end positioned for engagement with the tensioned auxiliary valve, and
a pin and slot connection between the plate and rod permitting movement of the rod independently ofthe plate and said plate being manually Y( )perable for moving the rod into engagement with the auxiliary valve to open the same, and
saidrtlifermostatic element normally occupying a Vposition permitting shifting movement of the VVrod for closing movement iliary Valve.
