To all/whom, t may concern Be itiknown that I, HARvY C. YINGLING, a citizen of the United States, residing at Baltimore, in the btate of Maryland, have invented new and useful Improvements in Controlling Devices for Gas-Burners, of which the following is a specification.

This invention relates to controlling devices for gas burners, and particularly to a device wherein the valve of the supply source is opened when weight is applied thereto ind closed when the weight is removed thererom.

An object of the invention is the provision of Va device of this character which may be used in connection with cook stoves and which will embody a movably supported main burner connected directly with the controlling valve in the supply source and adapted to open the valve when Ya utensil is in an applied position above the burner.

A furtherV object of the invention is to provide a pilot burner located adjacent the main burner for instantly furnishing an igniting burner for the main burner when the latter is depressed through the weight ofthe utensil.

A still further object of the invention is the provision of means whereby the controlling valve will be made responsive to open to diiferent degrees according to the amount of fuel that it is desired to admit to the main burner.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings: Figure 1 is a vertical section through the controlling device, showing the application thereof to a movably mounted main burner; Fig. 2 is a section on line 2 2 of Fig. 1; and Fig. 3 is a section on line 3-3 of Fig. 1.

The controlling device comprises a fuel and airfeeding pipe 1 having its intake end provided with the usual iiared mouth or funnel 2 having perforations 3 in its crown and a revolving regulating valve 4, the latter being adjustable across the perforations so as to regulate admission of air to the burner. The pipe 1 at its opposite end is curved outwardly at 5 where it is provided with a reduced section 6. Said section is vertically-disposed and is shown to slidably accommodate a vertical sleeve 7 on a main burner 8. A relatively light spring 9 is interposed between the sleeve 7 and the shoulder 10 of the pipe 1 and is designed to exert its force to normally hold the main burner in an elevated position.

At the large end of the funnel portion 2 of the pipe 1 is a valve casing 11 having a branch connection 12, to which may be connected the usual gas supply pipe, not shown. The connection 12 is alined with a feed noz- Zle 13 carried by the valve casing and extended through the funnel end 2 of the pipe 1 in the usual well known manner. The connection 12 intercepts the valve passage 14 in the valve casing and is designed to establish direct communication with the nozzle 13 when the valve of the device is opened. rIhe valve casing slidably supports a valve 15 having an upper stem 16 and a lower stem 17, the latter being slidable in a bore 18 in the lower end of the valve casing while the portion 16 is slidable in the upper portion of the valve chamber and through a gland 19. A spring 2() is interposed between the upper end of the valve and the gland 19, and is adapted to exert its force against the valve to normally hold the same against its seat 21 in the casing below the connection 12, the relative positions of the valve seat 21 and the connection 12 being such that the valve 15 will eifectually close the passage in said connection 12 when the valve is closed.

The portion 17 of the valve terminates below the valve casing 11, being preferably rounded at 22 and loosely seated in a corresponding depression 23 in a rocking lever 24. The lever 24 is mounted for pivotal movement at 25 upon a bracket 26 which extends from the pipe 1. The short end 27 of the lever 24 is operatively connected at 28 with the lower end of an actuating rod 29, the upper end of the rod having threaded connection at 30 with a boss 31 formed on the main burner. A pilot burner 32 has its upper end 33 disposed with such relation to the main burner that the flame from the former may be made to ignite the gas as it discharges from the main burner whenthe valve 15 is open. The pilot burner includes a pipe 34 having va controlling valve 35 therein which may be actuated manually to regulate the discharge of fuel to the pilot burner as will be understood. The pipe 35 is extended through the branches 36 and 37 to the branch connection 12 of the valve casing 11, so that it may be constantly supplied with gas and the pilot burner maintained in a lighted condition as long as may be desired by the operator. On the lever 24 and between the pivot 25 of the lever and the point of engagement of the lever with the valve stem 17 is mounted an adjustable weight 38 which may be placed in any desired position upon the lever between the points above specied so as to regulate adjustment of the valve under the action of the weight applied to the burner. It is, of course understood that when a comparatively light utensil is applied to the burner the weight 28 may be adjusted near the pivot so as to permit the valve 15 to readily open under the weight of the utensil. If it is desired to only admit a small portion of fuel to the burner the weight 38 may be adjusted to a point near the point of engage ment of the lever 2a with the valve stem 17, so as to permit the weight to assist in the action of the spring 2O toward resisting movements of the valve.

From the construction of the device described,it is obviously seen that on the application of a utensil to the main burner, the lat-ter will be moved in a downward di Y rection carr ino` therewith the actuatinfr rod When the utensil is removed from the burner, the latter` will automatically return to its normal position and under the action of the spring, the valve 15 will be closed.

F rom the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention as claimed.

Having thus described my invention, what I claim is 1. In an automatic controlling device for gas burners, a main burner, a member supporting the burner for vertical movements and including a fuel feeding pipe leading from the burner and terminating in a flared mouth, a valve casing located at one side of the mouth and provided with a nozzle eX- tending into the mouth, a pipe connection leading t-o the valve casing, a rocking lever ymounted on the support, a connection between the burner and one end of the lever, a` valve slidable 1n the valve casing, a seat formed in the casing at a point directly below said pipe connection, a gland iitted to `the upper end of the valve chamber, an upper stem carried by the. valve and slidable through the gland, a spring interposed between the valve and the gland and normally holding the valve against the seat, the oppo-V Y site end of the rocking lever havinga de- Y pression therein, and a lower stem formed on the valve and extending below the bottom thereof and having a rounded portionv loosely fitting in the depression. y .Y
