. (NoModeL) F FRENCH. PHOTOGRAPHIG PRINTING FRAME. No. 304,421. Patented Sept. 2, 1884.

WiLn sss. I InvEnLuT.




SPECIFICATION forming part of Letters Patent No. 304A21, dated September 2, 1884.

Application filed May "I, 1884. (No model.)

To all whom it may concern:

Be it known that I, FRANK FRENCH, of Lawrence, in the county of Douglas and State of Kansas, have invented a new and useful Attachment for Photographic-Printing Frames, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings.

My invention relates to photographic-print ing frames, and has for its object a simple, inexpensive, and secure support for said frame, whereby it may be held at any desired angle.

To this end it consists, essentially, in the novel form of the support, substantially as and for the purposes presently described.

In the drawings, Figure 1 is a perspective view of the frame and support. Fig. 2 is a detail perspective view of the support.

The frame A is of ordinary construction, suitably made to receive and retain the negatives, &c., as is usual.

In photographic printing it is desirable and frequently necessary to set the frames up out in the open air. In windy weather they are in danger of being blown down, resulting in broken negatives and spoiled prints. It becomes considerable of an object, therefore, to provide a support which will be simple and easy of manipulation, and at the same time secure in use, and this I attain by my novel form of support. This support B is composed of the side or pivot arm I) and the base-arm b. The arm I) is bent and extends at right angles to arm I), and in practice I prefer to form the support of a single metallic bar, bent in the L shape shown, to form the two arms I) Z). The end of the arm I) is pivoted at O to the side of the frame. The arm I), it will be seen, extends at right angles to the arm b, and parallel to the base of the frame, so that in use on the printing shelf or base the arm b and the base of said frame will rest in the same plane, as will be understood from Fig. 1.

In use the point of the base-arm is inserted through a staple, screw-eye, or other suitable stop, (I, secured in the printing-shelf D, and

- this secures the frame from being blown or jarred down, and obviates the danger of breaking before referred to. This disposi tion of the base-arm also secures same so it will not slip on the shelf when the frame is inclined at an obtuse angle, as is frequently desirable in order to secure the direct action of the suns rays.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. A support for photographic printing frames, composed of the side arm pivoted at one end to the frame, and the base-arm extended at right angles from the opposite end of the side arm, and adapted to be inserted through a staple or other suitable stop, substantially as set forth.

2. The combination, with the frame, of the L-shaped support having its side arm pivoted at one end to the frame. and its base-arm extendedat right angles from the opposite end of said arm, and adapted to be inserted through a staple or eye, substantially as and for the purposes specified.
