FLASH-LIGHT GS-BURNER.

SPECIFICATION forming part of Letters Patent No. 695,014, dated March 11, 1902.

Application filed November 14, 1901. Serial No. 82,316. (No model.)

To al whom it #my concern:

Beit known that I, DELL WARD, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented a new and useful Flash- Light Gas-Burner, of which the following is a specitication'.

My invention is an improved automaticallyoperating flash-light gas-burner especially adapted for illuminating glass signs and for analogous uses; and it'consist-s in the peculiar construction and combination of devices hereinafter fully set forth and claimed.

In the accompanying drawings, Figure l is a sectional view of an automatically-operating Hash-light gas-burner constructed in accordance with my invention. Fig. 2 is a similar view showing a modification.

' In carrying out my invention I employ an expansible gas-holder l, wh ich may be of any suitable construction and is here shown as comprising a Water-seal chamber 2 and a vertically-movable bell 3, the lower side of which is disposed in said Water-seal chamber. A gas-pipe 4, which extends upwardly in the gas-holder from the bottom thereof, is adapted to supply gas to the gas-holder from any suitable source.

The bell 3 or vertically-movable member of the gas-holder is here shown as provided with a burner 5, which communicates with an opening 6 in the upper end of the bell. A valve 7 is provided, which in coaction with the said opening regulates the escape of gas from the gas holder. The valve is here shown as hinged at one end under the top of the movable element of the gas-holder, as at 8, and as being disposed to cover the opening 6, as shown in Fig. l. A guide 9 depends from the upper side of the bell or movable element of the gas-holder and limits the movernent of the said valve. In the form of my invention shown in Fig. l the valve 7 is provided with an orifice l0 of slight diameter to constantly supply the tip of the burner with a small quantity of gas,so that a small iiame may be kept constantly burning for the` purpose of igniting the larger volumes of gas consumed intermittently by the operation of the burner in the production of the dash-lights. An

operating-rod 11 is connected to and depends lower portion of the rod 11 operates in a guide 2, which projects from one side of the gassupply pipe 4,' and the lower end of said rod l1 is bent to form a trip-arm 13, which, in c0- actionwith said guide l2, which also forms a stop by arresting the ascent of the rod ll near the limit of the upstroke of the bell or movable element of the gas-holder, causes said rod to open the valve 7, and thereby permit the gas accumulated in the gas-holder to be fed to the burner 5 and burned brilliantly, creating a iiashing light which endures during the descent of the bell or movable element of the gas-holder.

It will beunderstood that the pressure 0f the gas under the bell or movable element of the gas-holder will keep the valve 7 closed and cause the said bell to rise until the trip 13 of the rod ll by engaging the guide and stop 12 opens said valve, as hereinbefore de scribed. As the gas is being supplied to the burner during the downstroke of the bell the pressure thereof on the valve is diminished and the Weight of the valve, together withthat of its operating-rodll, keeps the valve open during the descent of the bell and While Vthe flashing light is burning.

In the modiiied form of myinvention shown in Fig. 2 the gas-pipe 4 is provided with a by-pass, here shown as a pipe 14 of diminished diameter, which leads to an igniting constantly-burning burner 15, disposed in such relation to the burner 5 as to ignite the gas, which escapes from the latter intermittently by the automatic operation of my improved burner.

I do not desire to limit myself to the precise construction and combination of devices herein shown and described, as it is evident that modiiications may be made therein without departing from the spirit of my invention.

IOC

In practice I provide the seal-chamber With vertical guides 16, which project from the upper end thereof, and provide the upper end of the bell 3 with a stop, here shown as a transversely-disposed bar 17, the ends of which operate in said guides. Said guides and stop limit the ascent of the bell.

Having thus described my invention, I claiml. An intermittently-actinggasburnercomprising a gas-holder having an element movable in one direction by the pressure of the gas therein, said movable element having a gas-escape passage, a valve, carried by said movable element, to close said gas-escape passage and maintained in closed position by the pressure of the gas during the outstroke of said movable element, and a connection between said valve and a xed point to open said valve at the limit of the outstroke of said movable element, substantially as described.

2. In a gas-burner of the class described, the combination of an expansible gas-holder having means to supply gas thereto, the movable element of said holder having a gas-escape passage, a valve pivotally connected to and carried by said movable element and actuated by the pressure of the gas to close said passage during the outstroke of said elem ent, and means to open said vvalve at the limit of the outstroke of said movable element, substantially as described.

3. In a gas-burner of the class described, the combination of an expansible gas-holder, having an element movable in one direction by the pressure of the gas therein, said movable element having a gas-escape passage, a valve to open and close said passage, said valve being movable with said movable element and maintained in closed position by the pressure of the gas during the outstroke of said movable element, and means to open said valve at the limit of the outstroke of said movable element and close said valve at the limit of the reverse stroke of said movable element, substantially as described.

4. In a gas-burner of the class described, the combination of an eXpansible gas-holder, having an element movable in one direction by the pressure of gas therein, said movable element having a gas-escape passage and a burner to Which said passage leads, a valve to open and close said passage and maintained by the pressure of the gas in a closed position during the outstroke of said movable element, said valve having a gas-passage of reduced capacity therein, and' means to close said valve at the limit of the instroke of said movable element, substantially as described.

5. In a gas-burner of the class described, the combination of an expansible gas-holder, having an element movable in one direction by the pressure of gas therein, said movable element having a gas-escape passage, a valve, carried by said movable element, to open and close said gas-escape passage, an operating element connected to said valve and having a trip and xed stops, alternately engaged by said trip, to open and close said valve at the limits of the strokes of said movable element, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afxed my signature in the presence of two Witnesses.

DELL VARD.
