MELVIN DE VER WESTCOTT, OF CORTLAND, NEW YORK, ASSIGNOR OF ONE-HALF TO LYNN R. LEWIS, OF SAME PLACE.

FLASH-LIGHT BURNER.

SPECIFICATION forming part of Letters Patent No. 526,661, dated September 25, 1894.

Application filed March 7, 1894:. Serial No. 502,754. (No model.)

To all whom it may concern.-

Be it known that I, MELVIN DE Van Wnsn.

COTT, a citizen of the United States, residing at Cortland, in the county of Cortland and State of New York, have invented certain new and useful Improvements in Flash-Light Burners and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I i r This invention relates to certain improvements in attachments to gas orother burners, whereby an illuminating powder is caused to be thrown or projected into the flame to prduce an artificial light, or flash-light. as it is commonly called for photographic pur-' poses; and it consists in providing the burner with a pair of pivoted arms, which carry, re

spectively, a powder-charge pan and a shield or target and are operated, through a suitable connection, by air-pressure acting upon a piston, as will be hereinafter more fully described and specifically set forth in the claims.

The principal object of the invention is to produce a flash-light burner, which shall beof sufficient capacity to give an intenseand brilliant light for the requisite exposure, and which shall be simple in construction and effective in operation, This object is accom-' plished by the mechanism illustrated in the accompanying drawings, in which- Figure 1 represents a perspective view of my improved device; ,Fig. 2,-a side elevation of an ordinary gas-burner, showing the wings or arms, slightly in perspective, and the angleslever attached thereto, and in position to be operated, and Fig.3, asimilar view, showing the position ot the Wings or arms after the operation of throwing or projecting the illuminating-powder has been performed.

Referring to the drawings-the numeral 1 indicates the base, which is provided with a hollow vertical standard, 2, in which operates a sliding arm, 3, carrying at its upper end, in a slightly inclined position, a vertical gaspipe, 4, which is provided with two sets of horizontally extending branch-pipes, one set 5 and 6, beingsecured above the point of attachment with the arm 3 and the

other set

7 and 8,below said point of attachment. Each of said branch pipes is providedwith two burners a a, of the ordinary pattern, the upper end of the pipe 4 being also provided with a like burner a, and the entire series of burners is by means of pivots 12. The wing or arm 10 carries at its outer end a pan, 13, and the wing or arm 11 carries a shield or target, 14, the purpose of which will be made apparent.

Pivoted to the branch pipes, near each burner, is a right angled lever 15, which has the end of its horizontal arm provided with a hook, 16, to which is attached one end each :of two links, 17 and 18, the other end of each link being secured, respectively, to one of right-angled lever, 19, and on each branchpipe of the lower set, at opposite sides of said vertical pipe, is pivoted a similar lever 20, the purpose of which will presentlyappear.

As one of the objects of the invention is to throw the illuminating-powder into the flame of each burner simultaneously, it will -be seen that the whole number of levers should be so connected, oneiwith the other,

as to render this object of easy and instantaneous accomplishment. These connections are made in the following manner: The vertical arms of the levers 15, pivoted on the branchpipes of set 5, are connected by a wire, 21, to the vertical arm of lever 19, which is pivoted on the branch-pipes of set 6, and the vertical 7 arms of the levers 15, pivoted on the branchpipes of set6, are connected by a wire, 22, with 'the vertical arm of the lever 19, which is pivward and is connected with the horizontal arm of the lever 19, which is pivoted on the lower branch-pipe of said set 5, and has its other end connected to an end 26, of a lever 27, pivoted centrally on the vertical pipe 4. A wire 28, has one end connected to the horizontal arm of the lever 19, which is pivoted on the upper branch-pipe of set 6, and passing downward connects with the horizontal arm of the lever 19, which is pivoted on the lower branch-pipe of said set 6, and has its other end connected to the end 26 of lever 27. Between the pivoted point of the lever 27 and its end opposite to end 26, are attached two

wires

29 and 30, the former of which is connected with the horizontal arm of the lever 20, which is pivoted on the upper branchpipe of set '7, and passing downward has its end connected to the horizontal arm of the lever 20, which is pivoted on the lower branchpipe of said set 7, and the wire 30 is connected with the horizontal arm of the lever 20, which is pivoted on the upper branchpipe of set 8, and passing downward has its end connected to the horizontal arm of the lever 20, which is pivoted on the lower branchpipe of said set 8.

Attached to the vertical pipe 4, at a point just below its connection with the sliding arm, is an air-cylinder, 31, provided with a piston, 32, which has its free end connected to the end 33 of the lever 27. The lower end of the cylinder is provided with an opening to which is fitted a flexible tube, which is provided with an airbulb 34, to be manipulated by the operative.

The horizontal arm of the lever 19, which is pivoted on the upper branch-pipe of set 5, is provided with a hook-end, 35, to which is attached one end of each of two wires, the other end of one wire being connected to one leg of the pivoted wing, 10, and the other end of the other wire connected to the leg of the wing 11.

The lower end of the vertical pipe 4 is fitted with a flexible tube, 36, which may be connected with the burner of a chandelier to supply gas to the burners of my improved device.

The operation of the device is as follows: As shown in Fig. 1, the wings or arms are in operative position. A small quantity of illu- .minating powder is placed in each pan. The

gas is turned on and lighted, and the camera adjusted. The operator then takes the bulb in his hand and by pressing it forces air into the cylinder against the piston, which is caused, by the air-pressure, to move upward. The end 33 of the lever 27 being connected to the end of the piston, it will be seen that when said piston is forced upward the lever 27 will be caused to turn on its pivot. The end 33 rising and pulling on the

wires

29 and 30 causes the wings or arms pivoted on the burners of the branch-pipes of

sets

7 and 8 to be instantly swung toward each other, which action causes the illuminating-powder in each pan to be projected into the flame and against the shield or target opposite. At the same time the end 33 of said lever 27 is being raised the end 26 is being depressed, and the pull on the

wires

25 and 28 causes the wings or arms on the branch-pipes of sets 5 and 6 and the wings or arms pivoted on the burner to to be also swung toward each other, which action causes the powder in each pan to be thrown into the flame and against the shield or target opposite. Thus it will be seen that the powder in every pan is instantly and simultaneously thrown into the flame of its respective burner, and an intense and brilliant light is produced for a duration of time sufficient to make the requisite exposure.

The shields or targets form an important element in the construction of my improved device, as they serve to insure the perfect combustion of the illuminating-powder. But for these shields or targets perfect combustion would not take place, as much of the powder, in the act of being thrown, would pass through the flame without igniting and be wasted. By the use of the shield or target that portion of the powder which would pass through the flame, when thrown from the cup or pan, is received against said target or shield and perfect combustion is effected.

The wings 10 are provided with a stop 37, which strikes against the burner and limits its forward movement, but the wing 11 is permitted to rest close to the flame at the end of its forward movement, so as to receive the powder at the nearest possible point to the flame in order to insure complete combustion. Theshield or target, when moved to its vertical position, together with the pan or cup, encircles the flame (and the burning powder) in such a manner as to create a draft, which produces an intensely hot flame, so that all of the powder is burned.

It will be understood that the flame maybe produced by a taper, gasoline-oil, or other means as well as by gas, and that the bulb can be made to operate the camera-shutter, simultaneously, with the flashing of the light, by connecting the opposite end of the bulb with said shutter by a flexible tube.

One of the principal advantages to be derived by constructing the pivoted-cup and shield or target to be thrown forward and backward, is that they will be normally away from the flame, so that all danger of melting, or being injured by the heat of said flame, is obviated, it being observed that immediately after each throw of the powder both the cup and shield are caused to move away from the flame, as hereinbefore stated.

Having thus fully described my invention,

what I claim as new, and desire to secure by means for throwing or depositing an illumi-' for moving the discharge pan or cup toward the shield or target, substantially as specified.
