VALVE ACTUATED SWITCH Filed Sept. 24, 1928 2 Sheets-Sheet '2 I I mlawnmiu INVENTOR ATTORNEY Patented June 3, 19130 UNITED STATES PATENT OFFICE WALTER J. MACKEY, OF DETROIT, MICHIGAN sir VALVE-ACTUATED SWITCH Application filed September 24, 1928. Serial No. 308,109.

This invention relates to igniting devices, and its general object is to provide an unproved switch for ignitors for fuel burners and the like that lights the fuel simultaieously with the opening of the control valve )f the fuel pipe line to the burner.

One of the important objects of the invention is to provide a valve actuated switch that can be easily installed on the valve of a )urner so as to be operated by said valve when the latter is opened, but does not in any way interfere with the proper operation thereof.

A still further object of the present invention is to provide a device of the character set forth, that is extremely simple in construction, inexpensive to manufacture and install, and efiicient in operation and service.

This invention also consists in certain other features of construction and in the combina- 2 tion and arrangement of the several parts. to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a side elevation of my improved igniting device applied to a valve.

Figure 2 is a sectional view taken approximately on line 22 of Figure 1.

Figure 3 is a sectional View taken approximately on line 33 of Figure 2.

Figure 4 is a sectional view taken approximately on line 1- 1 of Figure 1.

Figure 5 is a perspective view of the upper plate which forms a part of the contact-breaking means of my device.

Figure 6 is a similar view of the lower plate which cooperates with the upper plate.

Referring to the drawings in detail, the reference numeral 1 indicates the core of a valve for controlling the supply of fuel to a gas burner and the like, and 2 indicates the casing for the core which as clearly shown in Figure 3 has extending from diametrically opposite sides thereof nipples 3 that are threaded for the purpose of being disposed in the fuel supply pipe line for a burner or the like as will be apparent.

The casing is reduced at its upper end to provide a shoulder, and secured to the reduced portion through the medium of a screw 1 is a sleeve 5 which has formed therewith and extending therefrom a substantially rectangular shape projection 6 provided with a longitudinally disposed groove 7 and an outwardly inclined top 8.

Arranged for slidable movement in the groove 7 as clearly shown in Figure 3 is the bottom plate 9 that is provided with a longitudinally disposed slot 10 which accommodates the head 11 of a bolt 12. The head 11 is in the form of abearing for slidably receiving the bottom plate 9 and is formed with a cap for engagement with the plate as shown. The bolt 12 is passed through aslot 13 formed in the projection 6 and is adjustably received in the slot 13 by a nut. The forward end of the plate 9 is reduced and formed with and rising from said forward end is a lug 1 L having a beveled upper side as best shown in Figure 3.

Mounted for slidable movement on the inclined top 8 of the projection 6 is an upper plate 15 which cooperates with the lower platethrough the instrumentality of a lug 16 that depends from one end of the upper plate 15 and is arranged for engagement with the lug 1 1 during certain positions of the plate 15. The upper plate 15 is formed with a centrally disposed opening to accommodate the shank of a headed stud 17 and secured to the stud 17 is one end of a link 18 while the opposite end of said link is pivotally secured to a stem bracket 19 that is fixed in the reduced upper end of the core 1 whereupon movement of the core through the instrumentality of its handle for disposing the bore of said core in registration with the bores of the nipples 3 will operate my device in a manner which will be presently described.

Secured to the sides of the projection 6 are strips 20 having flanges 21 bent at right angles to the bodies thereof and overlying the upper plate 15 to hold the latter in op erative position with respect to the inclined top.

(Iii

ranged in the path of the last mentioned lug.

In a valve-actuated switch, a sleeve, a projection formed with said sleeve and being provided with a groove with a slot communicating with said groove, a slotted plate mounted for slidable movement in said groove, means passing through the slots and slidably securing said plate in said groove, a second plate mounted for slidable movement at an inclination, a movable stem bracket, and a link between the stem bracket and inclined plate for moving the latter, lugs formed with said plates and disposed in cooperative association with respect to each other.

6. In a valve-actuated switch, a pair of sliding plates, one of said plates being inclined, lugs formed with said plates and being arranged whereby the lug of one plate engages the lug of the other plate for mov ing said last mentioned plate, spring means for urging said last mentioned plate in a di rection opposite from that in which it is moved by the lugs, a spring pressed plunger bolt arranged in the path of the lug of the last mentioned plate, and the lugs being formed to cooperate for carrying the last mentioned plate to a position to cause the lug Ehereor to momentarily contact the plunger olt.

In testimony whereof I afiix my signature.

WALTER J. MACKEY.
