GEORGE ALBERT LEY, OF CHICAGO, ILLINOIS.

PHOTOGRAPHIC FLASH-LIGHT BAG.

1 b all whom it m (1 2 concern Be it known that I, GEORGE lrLnnnT Lnv, a citizen or the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Photographic F lash-Light- Bags, of which the following is a specification.

This invention relates to improvements in flash light bags for use by photographers and has particular application to a collapsiblebag frame.

In carrying out the present invention, it is my purpose to provide a flash light bag frame which may be readily and quickly collapsed and folded into small compass so as to facilitate transporting or storingof the structure and which, when in operative position, may be adjusted to any desired angle.

A further object of my invention JS tO provide a device of the class described which will inclose the flash light pan so as to confine the smoke and gases incident to the ignition of the powder, and wherein the component parts will be so correlated and arranged as to reduce the possibility of derangement to a minimum.

'With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claim.

In the accompanying drawings: Figure l is a perspective view of a flash light bag constructed in accordance with the present invention. Fig. 2 is a similar view of the frame, the covering being removed. I Fig. 3 is a view in side ele ation showing the parts in folded position. Fig. l is a fragmentary longitudinal sectional view through the upper end of the device, parts being shown in elevation. Fig. 5 is a sectional view on the line 55 of Fig. 3. Fig. 6 is a sectional view on the line 6-6 of Fig. 3. Fig. 7 is a cross sectional view on the line 77 of Fig. 3. Fig. 8 is an enlarged fragmentary sectional view taken at right angles to Fig, 4.

Referring now to the drawings in detail, 1 designates a vertical staff comprising two sections 2, 3. Formed on the lower end of the section 2 is a disk 4, while formed on the upper end of the section 3 are disks 5, 5 spaced apart in parallelism and between the disks 5, 5 is placed the disk 4. Passed through alining openings formed in the cen- Specification of Letters Patent. fatgnte j S t 12 1916 Application filed April 19, 1915.

thereof formed to provide a thumb piece 11 and the opposite end formed with a dog 12 adapted to enter the registering notches 7 8 to hold the disks against relative movement. By means of this construction, it will be seen that the upper section 2 of the staff may be adjusted at any angle relatively to the section 3 and held at such angle. When it is desired to adjust thesection 2 relatively to the section 3 the lever 10 is swung about its pivotal connection with the lugs 9 to dis engage the dog 12 from the registering notches 7 8 in the disks 4: and 5. At this time the section 2 is swung to the desired position and when the particular adjustment has been reached the lever 10 is swung in the opposite direction to engage the dog 1 with the registering notches 7, 8, thereby holding the section 2 against further movement. The lower end of the staff 1 is secured to an appropriate form of collapsing stand 13 and the lower section 3 of the staff is preferably formed of telescopic sections as illustrated in. Fig. 1 so that the staff may be folded into a small space.

14: designates a collar which, in the present instance, is substantially rectangular in contour and formed on the collar 14- at the corners thereof and projecting outwardly therefrom are pairs of pivot ears 15, while formed on one side of the collar and extending outwardly therefrom is a pair of pivot cars 16. The pivot ears 16 receive and are pivotally connected to a pivot knuckle on the upper end of the section 2 of the staff 1 and pivotally connected to the respective pairs of ears 15 and projecting outwardly from the collar 14 are ribs 17 preferably, although not necessarily, formed of bowed spring steel. Slidably mounted within the collar 14: is a shank 18 having the upper end thereof formed with a head 19, while secured to the lower end of the shank is a collar 20 and formed on the collar 20 and radiating therefrom are pairs of pivot cars 21 spaced apart about the collar equal distances and corresponding in number with the pivot ears 15. Pivotally connected to the respective pairs of ears 21 are the inner ends of links 22 and the outer ends of the links 22 are pivotally connected with the ribs 17 respectively as at 28. Pivotally connected to the collar 20 is one end of an arm 24:, such arm having the remaining end thereof pivoted to the section 2 of the staff as at 25. Secured to the ribs 17 in some suitable man ner and inclosing the frame formed by the ribs 17 is a cover 26 formed of suitable fabric and inclosing the section 2 of the staff. Fastened to the section 2 of the'stail in some suitable manner is a pan 27 designed to receive the flash light powder and connected with the pan 27 is an igniting device adapted to be supplied with electric current by means of wires 28.

When the ribs 17 are expanded and the fabric 26 drawn taut, the upper portion of the section 2 of the staff and the pan 27 are inelosed by the bag structure thus formed so that when the powder on the pan 27 is ignited the smoke and gases will be eonfined within the bag structure. By means of the disks 1 and 5 and the dog 12 carried by the lever 10 the upper section 2 and the bag structure carried thereby may be adjusted to any desired angular position so that the light may be diffused through the front portion of the bag at any angle. When it is desired to collapse the bag structure the shank 18 is drawn upwardly within the collar is under the action of the head 19, and in the upward movement of the shank the links 22 draw the ribs 17 inwardly, the ribs swinging about their pivotal connections with the cars 15. Thus, the ribs may be folded in against the section 2 of the stall as clearly illustrated in Fig. 3 of the drawings. The sections of the staff may now be folded upon each other and the stand 13 collapsed, thus enabling the device to be packed in a small space for transportation or storage purposes.

In the present instance, spring latching fingers 29 are suitably secured to opposite sides of the collar 1& at the upper edge thereof and project upwardly from such collar and are adapted to engage a shoulder 30 formed on the upper end of the shank with the head 19. When it is desired to expand the bag, the head 19 is pressed downwardly, thereby sliding the shank 18 downwardly and expanding the ribs 17 under the action of thelinks 22, the arm 24 serving to guide the shank in its movement. As the head 19 is depressed, the shoulder 30 engages the spring latching finger and so nolds the parts in open position. It will be noted that the ribs 17 that project downwardly, when the bag is open, are relatively long as compared with the length of the ribs 17 forming the top portion of the structure, thereby enabling the central portion of the bag to be properly stretched.

iVhile I have herein shown and described the preferred form of my invention by Way of illustration, I wish it to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claim without departing from the spirit of the invention.

I claim:

A flash light bag comprising a staff, a collar pivotally connected. to the upper end of said staff and oifset therefrom, ribs radiating from said collar and pivotally connected thereto, a cover carried by said ribs, a flash light pan within the inclosure formed by said ribs and cover, a shank slidably mounted within said collar, link connections between the lower end. of said shank and said ribs, respectively, whereby the ribs may be actuated to open and closed positions in the movements of the shank, and cooperating means on said collar and shank for locking the shank in bag opening position.

In testimony whereof I aflix my signature in presence of two witnesses.
