J. O. JACKSON.
FLASH LIGHT GUN.
APPLICATION FILED Nov. 11, 1921.

Patented Nov. 28, 192,2.
To all whom it may concern Be it known that I, JAMES O. JACKSON, a citizen of the United States, residing at the city and county of' Denver and State 5 of Colorado, have invented certain new and useful Improvements in Flash-Light Guns; and I do 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, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.
This invention relates to flash lights and has special reference to a gun or revolver by means of which the flash light powders can be conveniently exploded.
In taking photographs, it is, of course, essential that the object to be photographed is suiiiciently well illuminated. In order to enable photographs to be taken at night, on dark days, or in dark rooms, it is customary to illuminate the object by means of burning magnesium powder, or what is generally referred to as flash light powder. Various means and methods have been devised and used for conveniently handling and igniting the flash light powders, some of which have been used with a greater or less amount of success.
It is the object of this invention to provide means for handling and igniting flash light oowders that shall be conveniently operated,
in section and Fig. 5 is a view showing my device in operation.
The same reference characters will be used to indicate the same parts throughout the several views.
My device consists of an ordinary reand which will be so designed that it will be possible to explode a single powder or several in quick succession.
` In order to more clearly describe my invention, I shall make reference to the accompanying drawing irr which Fig. l shows my improved flash light gun in side elevation, with parts thereof shown JAMES o.v Jackson, or DENVER, conoanno. FLASH-LIGHT GUN.
Application led November 17, 1921. Serial No. 515,843.

r carina,
volver of suitable caliber, such vas .44 or .50, from which the barrel has been removed and replaced by a barrel of special design. In the drawing l represents the hand grip, 2 the trigger, 3 the hammer, and 4 the` revolving cylinder, all of which are assembled and operate in the usual way. The barrel is of special construction and comprises a cylindrical portion 5 which is attached to the frame of the revolver in the manner of any ordinary barrel. rel, instead of being a cylinder throughout, is flattened and widened, in the manner indicated by the portion designated by numeral G in Figs. l, 2 and 3, and terminates in a fiat thin opening? which is arranged transverse to the vertical plane of the revolver handle in the manner shown in Fig. 2.y
The flash light powders 8 are p acked within an ordinary copper or paper cartridge 9, which is provided with an ordinary percussion primer 10. The powder is held in place within the cartridge by means of a piece of wadding 1l of any suitable material, but preferably composed of wax. The end of the shell is crimped slightly, as shown at l2, for the purpose of holding the My bar- My device is operated in the same manner as any ordinary revolver, the charge 8 of flash light powder being ignited by the action of the percussion cap l0; the burning powder will then be forced out through the flattened end of the barrel and will produce a fan-shaped flare 13. il is made of wax, it will be melted by the intense heat and will pass out into the atmosphere in a molten or gaseous state.
In Fig. 4 I have shown a slightly modiiied form of opening in the discharge end of the barrel, the elongated opening 7A being somewhat narrowed at its central point whereby there will result a greater tendency to spread the vapors as they emerge Since the wad From the above 1t will be seen that I have provided a flash light gun that can be conveniently carried and operated, and which will enable the operator to explode several charges in rapid succession if he finds it I am aware that the results aimed at by me may be attained by means that may be specifically dierent from that disclosed by me, and I desire that my disclosure shall he taken in an illustrative and not in a limiting sense.
Having. now described my invention, what I claim as new is:
A. flash light gun comprising a Chamber adapted to Contain a Hash light powder,
means adapted to ignite the powder, an extended barrel communicating with said chamber, said barrel extending in the same general direction as the chamber, the end of the barrel that connects with the chamber having a cylindrical opening, While the other and outer end has a long narrow opening` constricted at its center.
ln testimony whereof I affix my signature.
JAMES O. JACKSON.
