FLASH-LIGHT DEVICE.

Specification of Letters Patent.

Application filed August 11, 1905. Serial No. 273,733.

To all whom, it may concern:

Be it known that I, TAKENARI AZUMA, a subject of the Mikado of Japan, and a resident of Kanda, Tokyo, Japan, have invented a new and Improved Flash-Light Device, of which the following is a full, clear, and exact description.

This invention relates to improvements in flash-light devices for use in photography, the object being to provide a flash-light lamp or device that will be simple in construction and so arranged that the flash will be directed upwardly and laterally in a thin sheet.

Other objects of the invention will appear in the general description.

I will describe a flash-light device embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is an elevation of a flash-light device embodyingmy invention. Fig. 2 is a vertical section thereof. Fig. 3 is a front elevation, and Fig. 4 is a top plan. I

The device comprises a block or body portion 1 of wood or other suitable material, having a socket member 2 for receiving the upper end of a standard 3-. Secured to the front of the body portion is a pan consisting of sheet metal 4, which is designed to receive the flash powder-such for instance, as magnesia. This pan is open at the sides and also open at the top, the opening at the top being comparatively narrow. To provide for this narrow opening at the top and also to provide sufficient space for the powder in the lower portion of the pan, the outer wall of saidpan is inclined upward and inward to- The igniting device for the powder consists of a tube 5, removably engaged in an opening formed in the ger 11 passes.

body portion, the end of said tube being extendedinto the opening and provided with a slot 6, through which a fulminant cap 7 may be passed. Attached to the tube 5 at the rear side of the body portion is a triangular plate 8, which is normally seated in a recess formed in said body portion and is held by buttons 9. The rear end of the tube is provided with a cap or cover 10, provided with an opening through which the stem of a plun- This plunger 11 is designed to be forced against the paper cap 7 to explode the same by means of a hammer 12, pivoted to brackets 13 secured to the body portion 1, and the said hammer is forced against the plunger by means of a spring 14, one end of which is secured to the hammer, while the other end is secured to the body portion. The hammer 12 is designed to be engaged by a latch-arm 15, extended from a lever 16, pivoted on the body portion, and on the free end of this lever 16 is a plate 17, designed to be struck by a cap 18, movable on an air-tube 19, with which a pneumatic bulb 20 is connected by a rubber tube 21.

In the operation, when the parts are in the position indicated in the drawings, pressure on the bulb 20 will cause the part 18 to press against the plate 17, moving the arm to release the hammer 12, which, through the agency of the spring 14, will swing over and strike upon the plunger 11, thus exploding the paper cap and igniting the flash-powder.

It will be noted that a flash-light device embodying my invention is of very simple construction and may be readily operated.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A flash-light device comprising a body portion, a pan thereon open at the sides and top, the opening at the top being narrow, a tube extended removably through the body portion into the pan and adapted to receive an exploding medium, a plunger for operating in the tube, and a spring-actuated hammer for forcing the plunger against the igniting material.

2. A flash-light device, comprising a body portion, a pan thereon, a tube removably extended through the body portion and projected into the pan, the said tube having a slot through Which an igniting medium may pass, a plunger operating in the tube, a springactuated hammer for striking the plunger, a l1olding-latch for said hammer, and a pneumatic for releasing the latch from the hammer.

3. A flash-light device, comprising a body portion, a pan thereon having its outer wall inclined upward and inward, or toward the body portion, a tube removably extended through the body portion and into the pan, said tube having a slot through which an igniting medium may pass, a plunger operating in the tube, a spring-actuated hammer for striking the plunger, a latch for holding the hammer in one position, a lever on which said latch is mounted, a plate on the front Patented Feb. 27, 1906.
