PHOTOGRAPHIC FLASH-LIGHT APPARATUS- SPEGIFIGATION forming part of Letters Patent No. 754,487, dated March 15, 1904.

- Application filed July '7, I903- $eria1No. 164,518. (No model.)

To all whom, it may concern:

Be it known that we, IRVING G. McCoLL, of the borough of Manhattan, county of New York, and MAXIMILIAN KLAIBER, of the borough of Brooklyn, county of Kings, city and State of New York, both citizens of the United States, have invented an Improvement in Photographic Flash-Light Apparatus, of which the following is a specification.

In the practice of flash-light photography difliculties have been experienced from the presence of the smoke resulting from the flash. This smoke is not only very objectionable, but its presence interferes with the operations of additional flashes and prolongs the necessary time of exposure.

Our invention relates to a device for catching and temporarily confining the smoke, so as to prevent its visible presence in a room or apartment, and which device can be operated to discharge the smoke into the open air.

In carrying out our invention we provide a flexible bellows-like structure of flexible material closed at one end and at the other end connected to a frame having swinging slats. This latter frame is adapted to be connected to the uprights or posts of an inclosure in which the flash is made. A suitable base supports this inclosure, one side of which is to be surfaced with transparent material, while the other sides thereof are opaque and preferably reflective to direct the light through the trans parent side. The latter parts are separable from the former, and'some of the latter parts are separable from one another, so that the parts may be brought into acompact relation where they will occupy only a minimum amount of space for transportation or storage.

In the drawings, Figure 1 is a vertical section and partial elevation representing our invention. Fig. 2 is a plan of the frame having swinging slats; and Fig. 8 is a plan and partial section of the base and parts connected therewith below said frame, Fig. 2.

0 represents a collapsible bellows, prefer-- ably constructed of light-weight flexible material, having the upper end a closed and provided with a suspending-eye, and we prefer to employ wire frames 2 within the series of most distended portions of the bellows, so as assist in keeping the bellows in shape and supporting the same,,so as to prevent the bellows collapsing.

6 represents a telescoping rod-support, the upper free end of which is adapted to engage the supporting-eye at the top of the bellows and the lower end of which telescoping rodsupport is received in a bracket 0, connected to the base 0. I

0? represents a frame, preferably of wood,

at the lower end of the bellows a, secured to said bellows, which preferably extends around the outside of said frame and is secured to the outer surface thereof in any desired manner. The opening in this frame d is occupied by swinging slats e, which are connected together by a bar 8, causing the said slats to move together. The seyeral slats are provided with axes pivotally mounted in opposite sides of the frame 03, and the axis of the central slat passes through the frame at one side and is provided with a knob 4:, by which the center slat and through the intervention of the bar 3 all of the slats turn together to throw open the center of the frame or close the same up. The respective corners of the frame d are provided with clamps 5, and the respective corners of the frame 0 are provided with similar corner-clamps 6. Each of these clamps consists of a; tubular portion throughwhich passes a thumb-screw and parts at right angles to one another to fit the recessed corners of the parts cl 0 and perforated for screws which pass through the parts of said clamps into the frame at and base 0. These corner-clamps receive corner-postsf, the ends of the posts passing into these sleeves and being held thereto by the set-screws. These posts near their up- .per ends are provided with sleeves 7, which preferably are fixed to the posts.

7 A wire frame 9, conforming in outline to the base 0 and frame d, is provided with corner eyes or loops to set over the upper ends of the posts f above the sleeves 7 The sides 72. are formed of flexible. material and occupy three sides of the base 0, the lower portions of saidsides being preferably nailed to the edges of the base 0, and the upper part or edge passes as a loop over the wire frame 9. Thus three sides of the space between the frame d and the base 0 are inclosed or occupied by this flexible 'material. This material is not only flexible, but preferably opaque and of light color, at least on the inside, so as to be reflective. The fourth side is to be occupied by transparent material 71, which may be glass, mica, transparent celluloid, or other similar suitable material extending between two corner-posts and the base 0 and frame 0? and may be secured in position in any desired manner, such securing means, however, forming no necessary part of our present invention. On the side occupied by the transparent material 2 we prefer to employ a hood 12, formed of flexible material similar to that employed for the sides It, and which flexible-material hood is extends from one side of the wire frame 9 to a part of a bracket 8, the ends of which are preferably pivotally connected to clampingsleeves 9 upon two of the corner-posts f. This hood may be raised or lowered and adjusted for the amount of light to be flashed from the apparatus. We have not shown in connection with our improvement any lamp or pneumatic apparatus for producing the flash, as this forms no necessary part of our present invention, because any form of such apparatus suitable for the purpose may be employed and should be placed upon and supported by the base 0 within the sides It and transparent material or front of the apparatus.

In the operation of the device the bellows a is to be in a collapsed condition at the start, with the slats 6 closed in relation to the frame d. At the moment the flash is, made the bellows is to be raised, and so extended, and the slats e swung into the position, Fig. 1. It will be apparent that this action will createa partial vacuum in the bellows, so as to draw therein either a body of air or smoke that may be at the opening in the frame. Consequently the smoke of the flash will at once be drawn into the bellows, and when the bellows is fully extended it is to be supported upon the rod 6, and as soon as the flash is over and the smoke drawn into the bellows the slats e are to be closed, retaining the same within the bellows. The screws of the corner-clamps 5 of the frame d are now to be loosened, so that the frame d and bellows a may be lifted off the cornerposts and removed to the open air, where it is preferable to invert the bellows and frame, open the slats e, and collapse the bellows, which action will force the smoke out of the bellows into the open air, where the same will be discharged instead of, as heretofore, being discharged into the room where the flash is made.

WVe do not herein limit ourselves to the precise form of the apparatus shown nor to the precise details of the construction, as both of these may be modified without departing from the essential features of the invention.

We prefer to make the bar 3, that connects the slats 0, heavy, so that the same will act automatically to close or open the slats except "when positively opened by the hand on the no transparent medium in the front to direct the smoke into the bellows, the hood and bellows acting as a chimney. The material 2' in the front may be transparent or translucent. It acts to diffuse the light.

We claim as our invention I 1. In a flash-light apparatus, the combination with an inclosure in which the flash is made, of a device connected thereto, separable therefrom and progressively extensible so as to draw therein the smoke from the combustion of the flash-powder, means for closing said device and retaining the smoke therein and which means may after the separation of the parts be opened to permit the exit of the smoke.
