6 Claims.

This invention relates to the class of hangers or supports and pertains particularly to an improved supporting means for films for use during developing of the same.

The present invention has for its primary object to provide a novel film supporting device which is so designed that it may be employed for suspending a single large film of the X-ray or other type or a series of small films such as are used by dentists in connection with the X-raying of teeth, in such a manner in a developing tank that the films will be securely retained in position and the smaller ones thereof will be kept separate so that each may be readily identified after the development of the same is completed. Another object of the invention is to provide a film carrier or support having associated therewith a novel means for identifying films attached thereto so that it is not necessary in arranging m the films on the support preparatory to immersing them in the developing solution, to place the films in any definite order so that they may be properly identified when removed as each film is identified by suitable marking upon the part of u the support by which it is attached.

A further object of the invention is to provide a novel film clip having associated therewith means for making a record for the purpose of identifying the particular film which the clip engages.

Another object of the invention is to provide a supporting rack or bar designed to have a series of the above described identifying clips readily detachably connected therewith whereby any number of X-ray or other films may be mounted upon the support without regard to the order of the mounting and may be easily and quickly identified when removed after the developing operation is complete.

Other objects and advantages of the invention will become apparent as the description proceeds and the invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not to be confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing:

Fig. 1 is a view in elevation of the device embodying the present invention in use for the support of a single large film negative.

Fig. 2 is a view in elevation of one hanger bar showing the use of the same for the support of a number of small negatives.

Fig. 3. is a view in edge elevation of a hanger bar per se.

Fig. 4' is a view in plan of a film clip per se.

Fig. 5 is a longitudinal section on the line 55 of Fig. 4. =10:

Fig. 6 is a view in front elevation of the clip.

Referring now more particularly to the drawing, the numeral I generally designates one embodiment of the present invention whereby a single large film may be mounted for suspension 15- in a developing tank. This structure comprises a frame which is made up of the two side hanger bars I and cross connecting bars 2. Each of the hanger bars comprises a strip or band of metal 3 having one end turned or curved to form a susto pension hook 4. Extending longitudinally of one side of each hanger I is a band of metal 5 which is provided with a series of spaced parallel outpressed portions 6 and the areas between these portions are in abutting relation with the bar 3 and welded or otherwise suitably secured thereto so that the outpressed portions provide transverse uides I.

The cross bars 2 are of the proper width to slidably engage in any of the guides I but they are 30 preferably engaged in only the end ones as shown, and they may be secured therein by means of set screws 8 which are threaded through the end ofisets 6 for frictional contact with the bars 2 so that the hangers I may be maintained in any 35v desired spaced apart relation.

Each of the guides I is designed to receive the relatively long tail-like extension 9 of a clip member I0. Each clip member has a body portion II from which the tail 9 extends and an oscillatable portion I2 which is pivotally mounted upon the body and which is normally urged by a suitable spring in a direction to move the fixed and movable jaws I3 into gripping relation.

' The top and bottom sides of the body II and 5,. movable portion I2 of the clip are provided with apertures I4 which are formed by striking out a triangular section of the metal of the clip and one of these triangular pieces is turned to extend inwardly, as indicated at I5, crossways of the clip in back of the jaw to serve as a stop for limiting the movement of a film between the jaws. The apertures I4 are provided to permit of the easier and more thorough washing of the clips as they are shifted from one solution to another. I5.

The end of the tail portion 9 of each clip is provided with an aperture I6 and between the aperture and the clip proper there is secured to one face of the tail portion a white composition or Celluloid marking tag or strip I1 on which identification marks or symbols may be made by a suitable marking device such as a lead pencil or the like for identifying a film held between the jaws of the clip.

The tail portion 9 of each clip is ofa width to snugly frictionally engage in a guide 1.

In the use of the device as illustrated in Fig. 1, four clips are employed, two upon each hanger l, in the manner illustrated so that each" clip may engage a film adjacent one corner thereof to suspend the same within the frame which is formed by connecting the hangers l by the bars 2 in the manner illustrated;

For the use of the device in the developing of a number of small films such as a series of X-ray films of the type employed for X-raying the teeth, a hanger I will be employed alone as illustrated in. Fig. 2, with a number of clips engaged in the-guides? as shown, the clips being arranged to have their jaws alternately ppositely directed so that a series of films may be held in vertical edge of edge relation. 'These hangers imay be provided with any desired number of guides for carrying any number of film of an organization whereby a series or group of films maybe conveniently mounted upon a single hanger for suspension in a developing tank.

By providing the tail-piece on each. clip and the composition or Celluloid marking tag ini tegral therewith, the film carried by the clip may be marked for identification and thus when a set of films is to be developed at one time, it will not be necessary to arrange them in any particular order on the hanger so as to facilitate convenient identification after the developing is over, as each film will be identified by the mark- .ing upon the tag which forms an integral part In this way the possibility of gettherewith, connecting bars between the hanger bars each having an end slidably extended through a guide, and film engaging clips each including a gripping jaw and a tail-piece, the tail-piece of each clip being designed for frictional engagement in a guide whereby the jaws of the clips may be arranged for the suspension of a film between the hanger bars, and means for suspending the bars in a developing tank.

2. A film support or hanger, comprising a bar memberformed at one end to provide a sus- .-pension hook, means forming a series of guides transversely of said bar, and a clip member having a film gripping jaw and a tail-piece adapted for selective frictional engagement in said guides. 3. Afilm support or hanger, comprising a bar .member' formed at one end to provide a suspension hook, means forming a series of guides transversely of said bar, a clip member having a film gripping jaw and a tail-piece adapted for selective frictional engagement in said guides, and means upon the said tail-piece of the clip facilitating the making of a record thereon.

4. A support of the character described, comprising a relatively long flat strip of material formed at one end to provide a suspension hook, a second strip secured longitudinally of and on one face of the first strip, said second strip having longitudinally spaced transversely extending offset portions forming with the first strip guide openings, and a clip member having a relatively longfiat tail. portion adapted for selective frictionalengagement in said guide openings.

5. A supporting clip of the character described, comprising a body having a fixed lower portion and a movable top portion pivotally coupled therewith, the said portions of the body having coacting jaw members, resilient means normally urging said jaw members into gripping relation, the said bottom portion of the body having a relatively long tail-like extension of fiat form and provided at its outer extremity with an aperture, and a body of material secured to one face of said tail-like extension and adapted to have. a pencil record made thereon.

6. A supporting clip of the character described, comprising a body having a fixed lower portion and a movable top portion pivotally coupled therewith, the said portions of thebody having coacting jaw members, resilient, means normally urging said jaw members into gripping relation, the said bottom portion of the body having a relatively 1ong tail-like extension of flat form and provided at its outer extremity with an aperture, a body of material secured to one face of said tail-like extension and adapted to have a pencil record made thereon, and the said portions of the member having openings formed therethrough by striking inwardly a portion of the material of which the body is formed, the instruck portion of material from one body portion being disposed transversely of the body inwardly of said jaws to form a stop means for an article inserted between the jaws.
