4/% v BY Patented July 19, 1932 UNITED STATES BERNARD HENRI PAT? aria JEANNERET, OF LE LOCLE, SWITZEBLAND,1ASSIGEOR TO THE FIRM 'ELEGTROGAZ S. A., OF LE LOGLE, SWITZERLAND VALVE ACTUATOR For; A swrron Application filed October 18, 1928, Serial No. 313,354, and in Switzerland October 23, 1927.
This invention relates to a valve actuator for a switch which is particularly adapted for use with electric igniters for gas burners.
It is an object of the invention to provide simplified transmission means between the gas admission valve and the switch controlling the ignition circuit which is being closed upon opening the valve to form ignition sparks in proximity of the burner whereafter the transmission means will be held in inoperative position and remain unaffected by the operation of closing the valve or by any adjustment for the purpose of regulating the volume of the flame of the burner.
Fig. 1 is a diagrammatic view of the ignition system in elevation.
Fig. 2 is a plan view thereof.
Fig. 3 is a detailed view of the gas inlet valve in elevation and partly in section, showing the transmission parts connected therewith for actuation of the spark producing means.
Fig. 4 is a plan view of the gas valve and its associated parts, partly drawn in section.
Referring to the drawing: 36 indicates a transformer having its primary coil connected to a high voltage electric current net by means of the plug 37 One end of the secondary coil is connected to thehousing of the transformer which is itself mounted on the apparatus tobe heated by the gas burner A. The other end of the secondary coil is connected to the rod 38 which is mounted insulatedly with respect to the transformer housing and the burner A and ends in a rake 39 situated adjacent the burner A.
In the circuit of the primary coil is included an interrupter which is not illustrated and which has its control button at 40 cooperating with a second button 41 provided on the resilient rod 42.
The gas inlet valve will now be described with reference to Figures 3 and 4. The gas inlet pipe 13 is formed with a valve body C within which is disposed the valve plug D provided with a handle E. On the plug D there is mounted a pawl 1 pivoted at 2 and maintained in the position shown in Figure 4 by means of a spring 3. The pawl l-is arranged for cooperation with a rod 43 slidably engaged by a sleeve 20 placed over the gas pipe B, which rod abuts against the resilient blade42. y
Figure 4 shows in full lines the valve handle E in closed position and the whole system out of operation. When the valve is opened by turning the handle E in the direction of the arrow 7, the pawl 1, turning with the valve D pushes the transmission rod 43 and this latter displaces the resilient blade 42, the button 41 acting upon the button 40. When the valve handle E has arrived in the position a shown in dotted lines, the gas starts to flow through the pipe Band the button 40 has been displaced for the necessary amount to close the circuit of the primary coil. The fiow of current through the primary coil produces in the secondary coil a low voltage current of high frequency,
whereby sparks are formed between the rake 39 and the burner A, which sparks ignite the gas escaping from the burner A.
When the valve handle E is turned a little further than the position a, the face of the pawl 1 leaning against the transmission rod 43 slides off from the end face of this rod which is then pushed backwards into its normal position under the action of the resilient blade 42. During its back motion the v rod 43 slides over the back of the pawl 1 and holds this pawl against the action of the spring 3 in the position shown in dotted lines in Figure 4. The handle E can therefore be turned into any position according to the desired intensity of the flame, between the two positions shown a and b, 1) corresponding to the smallest flame, without the pawl 1 acting upon the transmission rod 43. When the handle E is turned in its closing position,
the pawl 1 is liberated from its position between the rod 43 and the valve body and is pushed outwardly under the action of the spring 3 so that the described mechanism is ready to function again.
I claim:
1. In a valve actuated switch, the combination with a fluid controlling valve plug, of a resilient contact operating member, a sliding rod adapted to actuate said member. a pawl rotatably mountedon the valve plug and IOU i to move adapted to engage said sliding rod, and a spring acting on said pawl to urge the pawl into rod engaging position.
2. In a valve actuated switch, the combination with a rotatable fluid controlling valve plug, of a resilient contact operating member, a sliding rod abutting against said member, a pawl rotatably mounted on the valves plug and adapted to engage said sliding rod said operating member upon rotation of the plug, and a spring urging the pawl into rod engaging position, said rod being adapted to be released by the pawl after'a predetermined movement of rotation of the valve plug and to be moved in opposite direction by said resilient contact operating member when re leased to hold said pawl in inoperative position against the action of said spring.
In testimony whereof I afiix my signature;
