HAND IGNITERS FOR GAS BURNERS Filed Sep'f.. 28, 1953 ATTORNEY United e Safes Paten-f O A 2,836,232 Y v HAND IGNITERS FOR GAS BURNERS Bevan Graham Horstmann, Bath, England Application september 2s, 1953, serial No. 332,509
9 claims. (ci. 15s-11s) This invention relates to igniting appliances for gas burners of the kind in which al pilot tubersupplies gas to an igniting burner associated with an electric filament energised by a dry battery, the passage of gas to the igniting burner being controlled by a manually operated valve which simultaneously operates a switch or Acontact device L in 'the filament circuit.
In prior British patent specification No. 477,498 there is described an improved Iappliance of this kind which is portable and capable of use as a hand torch and wherein the fiow of gas through the pilot tube is controlled by two valves, one being a manually operated main control valve and one a gravity valve which closes when the appliance is pointed upwardly so that in this position no llame at all will be projected or only a feeble flame unlikely to harm any persons in the vicinity.
The primary object of the present invention is to provide an igniter appliance of the kind referred to embodying a gravity valve functioning as in the invention of the aforesaid prior specification and also serving as the main control valve.
According to the present invention an igniting appliance of the kind hereinbefore set forth, and constructed as a portable device for use as a hand torch, is provided with a gravity valve member housed in a valve body feeding the igniting burner and normally held immovable in a closed position, manually operated means being provided to free the valve member and permit it to move by gravity into an open position.
In one way lof carrying out the said invention, there is provided a hand igniting appliance for gas burners which ycomprises a valve body axially movable within a casing on Ia central gas burner feed tu'be ixed relatively to the casing and terminating within the valve body, a gravity valve carried in the body and adapted to be pressed on to a valve seating inside the body by the end of said feed tube, a resilient device normally thrusting the valve body on to the gravity valve to close the valve, and operating means to move the body against the resistance of the resilient device to free the valve member (permitting the latter to open by gravity) and to close suitable contacts in the igniter filament circuit.
To enable the invention to be clearly understood an embodiment will now be described in greater detail, by way of example, with the aid of the accompanying drawing which shows a longitudinal section.
Referring to the drawing there is a main outer casing comprising the body 1 to which is screwed the housing 2 for a dry battery 3. The casing body 1 is fitted with a detachable nozzle 4 which carries a liner 5 fixed therein and an electric filament 6. An electrical insulating block 7 is mounted in the liner 5 and through this there extends a pair of conductive posts. 8 which carry the said lilament. In this embodiment the casing is of metal constituting 'an earth return for the filament circuit to the battery 3, but with a casing of insulating material an appropriate return lead would 'be provided. The other lead runs via a central gas burner feed tube 9, thence through a valve itl mice
housing body 10 to the central electrode 11 of the battery. The end 12 of the tube 9 constitutes a burner which is ignited when the gas flows over the energised filament 6, the flame being projected out of the nozzle orifice 13. The nozzle 4 is formed with a number of Iaxial slits 14.
The aforesaid valve housing 16 is axially movable within the casing 1 on the centrally disposed gas burner feed tube 9. To one end of the valve housing 10 a disc 15 is secured and this disc is axially slidable within the casing against the action of a compression spring 16 interposed between said disc and a fixed end plate 17. A contact stud 18 is carried lby the `dis'c and makes electrical contact with the central electrode 11 of the dry battery 3 when the valve housing 10 is moved against the force of the spring 16.
Within the valve housing 10 there is mounted Ia line of balls 20 the right-hand end one of which constitutes a loose valve member which together with the seating 21 comprises a valve for admitting gas from the branch 22 to'the housing and thence, via the feed tube 9 to the burner 12. The spring 16 normally presses the housing 10 and consequently the valve element 20 towards the feed tube 9, and thus the valve ball 20 is pressed solidly against the end of the tube 9 (with the interposition of the remaining balls 20). The end of the burner feed tube 9 is slotted at 25. If, however, the housing 10 is moved to the right (with respect to the drawing) in relation to the casing 1, against the action of spring 16 then the valve ball is freed, and is permitted to roll away from the seating, opening the valve, if the igniter should 'be tilted downwardly.
A trigger 23 is secured to the gas inlet branch 22 for the purpose of moving the housing 16 in the manner described so that it'slides on therelatively iixed tube 9. The inlet branch 22 is provided or formed with a grooved end 24 to receive a flexible gas feed tube (not shown) and leads to a passage in the trigger which communicates with the interior of the valve body through the valve seating 21.
