UNITED STATES PATENT Enron- EVAN D. EVANS, OF ITHAOA, NEW YORK.

FLASH-LIGHT MECHANISM.

QPECIFICATION forming part of Letters Patent'No. 536,276, dated March 26, 1895.

Application filed March 1894:.

To all whom it may concern:

Be it known that I, EVAN D. EVANS, of Ithaca, in the county of Tompkins, in the State of New York, have invented new and useful Improvements in Flash-Light Apparatus, of which the following, taken in connection with the accompanying drawings, is a full, clear,

reciprocated saw-toothed bars or rods which the disks.

engage with the caps or primers simultaneously, to offect the ignition of the flash powder in all of the cups simultaneously.

My invention consists in the severalnovel features of construction and operation hereinafter described and which are specifically set forth in the claims hereunto annexed.

It is constructed as follows, reference being had tothe accompanying drawings, in Which Figure 1, is a front elevation of the apparatus, the rod 11 being shown in the rear of Fig. 2, is a top plan view thereof, the standard being cut off, the rod 11 being shown in front of the disks. Fig. 3, is a side elevation of one of the flash cups, its

mounting and friction mechanism. Fig. 4, is a vertical section of same. Fig. 5, is a top plan thereof. Fig. 6, is a top plan showing .the primer holder open. Fig. 7 is an enlarged front elevation of the standard, the crank thereon, the connection to the friction bars, and the rod for operating said crank. Fig. 8 is a side elevation of said primer holder decached. Fig. 9 is a front elevation of the spring upon the crank-rod, part of said rod and of the standard. Fig. 10, is a front elevation, showing the cups mounted in a different manner, and a frictional ignition mechanism actuated in a somewhat different man- Serial No. 503,676. (No model.)

ner. Fig. 11, is a vertical transverse section of one of the flash cups, shown in Fig. 10,'

are adjustably mounted by means of set" screws 3- and 4=4: are the flash-cups mounted upon said arms, and vertically slotted to receive the reciprocating friction rod 5- which is provided with teeth 6 or otherwise roughened. These rods are connected by the pitmen '7' to the crank-disk 8 pivoted upon said standard so that the partial rotation thereof will reciprocate said rods. Under each cup aspring primer-holder -9'- is pivoted, provided with a receiver 10 which extends up through said arm 2- to or into the base of the cup, so as to bring the primer into contact with the teeth of said friction rod. A crank-rod -11- is connected to each crank-disk either on its front or rear side as shown in Figs. 1 and 2,

and provided with a spring 12 so that when it is pressed down, said spring is set,

so that when the trigger which holds said rod said crank-rod from the cranks, all of the.

flash-cup carriers can be dropped down together to make the apparatus portable.

In Fig. 10, the main frame comprises a base a, uprights b and transverse bars c screwed together so as to be readily taken apart for packing into small compass for a portable machine, an auxiliary frame, comprising the sides d and rods 6- connecting them, all screwed together and readily detachable for packing; said sides fitting loosely upon two or more of the bars -cand adapted to be reciprocated thereon to reciprocate the friction rods 6. Springs 7 h connect the auxiliary frame to the up rights. A piston rod -7c is connected to this latter frame, and is provided with an ordinary head within the cylinder --m to which the hose -mis connected leading to the bulb n or other source of power, by which said piston is actuated to slide said auxiliary frame to the left, against the springs and compress them, so that when the pressure is removed from said piston, they will force said frame back to its normal position. A similar cylinder and piston mechanism can be used to operate the trigger or catch in the construction shown in Fig. 1.

The flash-cups ccare suspended from or secured to the bars cand are provided with a threaded base, onto which the screw cap r is screwed to hold the nipple r by the engagement of their flanges, as shown, or in any other suitable manner. Said nipple is transversely slotted at -s to receive a fulminate or paper primer, and is also per forated transversely to said slot at s, said slot and perforation intersecting each other, and the rods e-- pass through said perforations, being provided with teeth, orotherwise roughened, as at t which will scratch and ignite each and all of the primers simultaneously and ignite the contents of all the cups (as gunpowder) and flash all of them si multaneously, whenever the auxiliary frame is actuated as aforesaid.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. A suitable support, supporting arms, flash cups mounted on the arms, and provided with slots through their bases, and friction rods having serrated surfaces and adapted to move endwise, combined with the spring primer holders which engage with the serrated surfaces on the friction rods, substantially as shown.

2. In a flash light apparatus, the standard, supporting arms connected thereto, flash cups mounted on the arms, friction rods provided with serrated surfaces, and passing through the cups, and the spring primer holders, combined with a crank or disk, and connecting rods between the disk and friction rods, substantially as described.

In witness whereof I have hereunto set my hand this 12th day of March, 1894.
