HOLDER FOR PHOTOGRAPHICFILMS.

Application filed May 23, 1925. Serial No. 32,499.

To all whom it may concern:

vide a device of the character mentioned capable of holding films while the latter are being immersed in the various solutions employed during the developing operation and also during the subsequent fixing, washing and drying operations.

It is still further an object of the invention to provide a holder in which different sizes of photographic films may be held with equal efiiciency.

The invention consists in a holder for photographic films as set forth in the follow specification, and particularly as pointed out in the claims thereof.

Referring to the drawings 2-- Figure 1 represents a front elevation of a holder for photographic films embodying my invention, a large film being illustrated in full lines supported in said holder and the position of a smaller film being illustrated in dotted lines.

Fig. 2 is an enlarged detail horizontal section taken on the line 2-2 of Fig. 1, illustrating one of the film clamps and the manner in which it grips the film.

Fig. 3 is an enlarged detail vertical section taken on the line 33 of Fig. 1 illustrating the clip for securing the free end of the arms in a position to support the larger sizes of films.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 1 represents a frame embodying therein a channel-shaped top memher 2 and another member 3, preferably constructed of heavy wire and bent to form a bottom portion 4 parallel with the top member 2 and side port-ions 5 and 6 which are parallel with each other. The side portions 5 and 6 of the member 3 are bent toward each other at 7 and 8 respectively and said bent portions are rigidly secured to the top member 2 in any suitable manner. The top member 2 of the frame 1 projects at 9 and 10 beyond the side portions 5 and 6 of the member 3 of said frame, thereby providing means for resting said frame upon the top edge of the various containers in which the developing and fixing solutions are contained and permit said frame and the film supported therein to hang in a vertical position in said containers.

Secured to the frame 1 at the top and bottom thereof are supporting means A and'B respectively, the supporting means A being secured to the top member 2 of saidfra-me and the supporting means B being secured to the portion 4 thereof. The supporting means A and B are identical in construction, each embodying therein a pair of X arms 11 and 12 which are fastened at 18 and 14: respectively to the frame 1 adjacent to the corners thereof. The arms 11 and 12 are constructed of a suitable resilient material as, for example, spring Wire and extend from the points 13 and 14 at which they are attached to the frame 1 approximately in opposite directions and intersect each other at a point approximately midway their length.

Each of the arms 12 and 13 [has a clamp 15 secured at the free end thereof, said clamp being constructed of a single piece of sheet material and embodying therein gripping portions 16 and 17 between which a film C is gripped at a point adjacent to the corner thereof, there being a spur 18, formed integral with the gripping member 16 which penetrates said film, thereby preventing the latter from slippingbetween the gripping members; The clamp 15 illustrated in the drawings is old and well known in'the art, and it is evident that any other suitable clamping member may be employed without departing from the spirit of this invention, said clamps being secured at the free end of the supporting arms.

The supporting arms 11 and 12 each have a clip 19 loosely mounted thereon, said clips being provided with a hook portion 20 of suitable shape to engage the frame 1 when the largest size of film is supported therein, it being necessary at such times to spring the arms 11 toward the top and bottom portions of said frame and secure said arms in the position illustrated in Fig. 1 in order to hold the larger sizes of films perfectly fiat. The position of the clips 19 may be varied upon the arms 11 and 12 as necessary for the larger sizes of films by sliding said clips upon said arms. When a smaller size of film, such as is illustarted in dotted lines,

is held within the holder, the, clips 19 are disengaged from the frame and the arms 11 and 12 are sprung inwardly and the clamps 15 are secured to said film. At such times, the tension of the arms 11 and 12 is sufficient to hold all of the smaller sizes of films perfeet-1y fiat.

All sizes of films that are longer than the width of the holder are held Within said holder as illustrated in the. full line position, While all sizes of films that are shorter in length than the width of the holder are P130 41 in said holder as illustrated in dotted lines.

The holder of this invention is constructed particularly for holding a type of photographicv film that is employed for X-ray Photographs and said holder is capable of holding with equal efiiciency all of the sizes of photographic films that are now employed in XrI'ELY Work, Whereas heretofore, so far as I am aware, it has always been neoessary'to employ a different size holder for each size of film.

The construction of the holder is such that the film's may be easily secured therein in the obscure light of a dark room.

I claim 1. A, holder for .a photographic film comprising, in combination, a frame, film supporting means located upon said frame and embodying therein a pair of resilient X arms,

' and means fast to each of said arms to grip a film and secure the latter thereto.

2,, A holder for a photographic film comprising, in Combination, a frame, film supporting means located upon opposite sides of said frame, each of said means embodying therein a pair of resilient X arms, and means fast to each of said arms to grip a film and secure the latter thereto.

3. A holder for a photographic film com prising, in combination, a rectangular frame, film Supporting means located upon opposite sides of said frame, each of said means embodying therein a pair of resilient X arms, said arms being secured to said frame adjacent to the corners thereof, and means fast to each of said arms to grip a film and secure the latter thereto.

1. A holder for a photographic film comprising, in combination, a frame, film supporting means embodying therein two sets of oppositely disposed and reversely arranged resilient X arms fast to said frame, and means fast to each of said arms to grip a film and secure the latter thereto.

5. A holder for a photographic film comprising, in combination, a frame, film supporting means located upon opposite sides of said frame, each of said means embodying therein a pair of resilient X arms, means fast to each of said arms to grip a film and secure the latter thereto, and means to hold the free ends of said arms adjacent to the side of saidframe.

6. A holder for a photographic film comprising, in combination, a frame, film supporting means located upon opposite sides of said frame, each of said means embodying therein a pair of resilient X arms, means fastto each of said arms to grip a film and secure the latter thereto, and means fast to each of said arms to hold the free ends of the latter under tension adjacent to the side of said frame.

A holder for a photographic film comprising, in combination, a frame, film supporting means located upon opposite sides of said frame, each of said means embodying therein a pair of resilient X arms, means fast to each of said arms to grip a film and secure the latter thereto and hooks slidably mounted upon said arms and adapted to hold the free ends of the latter under ten-v sion adjacent to the side of said frame.

In testimony whereof I have hereunto set my hand.

DANIEL INGVE.
