SINCLAIR TOUSEY, 013 GAR-DEN CITY, NEW YORK.

Y-RA'Y-FILM CARRIER.

To all whom it may concern:

Be it known that I, SINCLAIR ToUsnY, a citizen of the United States, and resident of Garden City, in the State of New York, have invented certain new and useful Improvements in X-Ray-Fihn Carriers, of which the following is a specification, covering subject matter of application 275,988, filed February 10, 1919.

My invention is designed to facilitate the handling of Xray films used in dental work and particularly for enabling the operator to remove the film from the carrier after exposure so that contact of the fingers with the film will be avoided and the liability of infection from the saliva of the patient will be reduced and with care entirely avoided.

In the drawings:

Figure 1 is a front view of a casing forming part of the complete film packet.

Fig. 2 is a rear view.

Fig. 3 a sectional view on line 33 of Fig. 1.

Fig. 3 is a view of the blank from which the main part of the film packet is made.

Fig. 4 is a sectional view of Fig. 1 on line In these drawings and referring to Figures 1 to 3*. 7 indicates the main body of the casing which is formed of metal preferably soft annealed and has its edge turned at 8 over its front face around three sides of the plate or body while the fourth side is provided with a free flap B which, as shown at 10, is doubled upon itself to provide an inwardly projecting flange extending along one side of the holder or carrier, which performs a similar function to that of the inturned flange or edge 8 extending along the other three sides of the holder, viz, to hold the film within the casing. The film (or films) is indicated at D, and at C a sheet of black card board or other substance opaque to light but transparent to the ray. This is also held by the flange or inturned edge. The front surface is as non absorbent as possible to protect the film from moisture when placed in the patients mouth.

To gain access to the film after exposure, for its removal from the holder, the free flap B is pulled upon; and this pulls down the flange or edge 10 and leaves an opening at this point through which the film can be taken from the holder quickly and with out danger of damage thereto and with less handling than would be the case if the narrow flange like 8 extended on all four sides and h ad to be pried up to get the film out of the case.

The less handling or manipulation the better as possibility of contact of the fingers with the face of the film is avoided and the operator is less liable to become infected from the saliva of the patient.

In this form of film carrier the side at which is located the black card board Or other substance used for the same purpose is exposed to the X-ray instrument, this side being marked front.

lit will be noticed that the finger piece or flap B is formed by an extension of the doubled back portion 10, and that the flap is turned over the edge of the packet and down on its rear face.

This construction permits the use of an outside cover C which is pasted over the entire front. The inside cover 0 is of waterproof black paper so that when the packet is in the mouth the film will not be spoiled by moisture reaching it. So, too, this inside water-proof cover will protect the film from spoiling in case the paste is too wet this paste being used for applying the outside black paper cover C.

It will be seen that although the outside cover C extends over the whole front face of the packet, being pasted to the flanges as at 8 and to the base of the finger piecev as at 10. the flap arranged as herein shown is readily accessible and by it the packet can be opened along the margin where the flap lies so that access readily may be had to the film for its removal.

ll claim:

1. An X-ray film packet comprising an outer case or carrier of a sheet of impressionable material having narrow edge portions turned upon itself on each of its sides to hold the film by overlying only a narrow marginal portion thereof, and an unsealed finger piece consisting of an extension of one of the turned edge portions doubled back upon and exteriorly to said edge and reaching beyond the margin of the packet, substantially as described.

2. An X-ray film packet comprising an outer case or carrier of a sheet of impressionable material having narrow edge portions turned upon itself on each of its sides to hold the film by overlying only a narrow marginal portion; thereof; and; an unsealed finger piece consisting of an extension of one of the turned edge portions doubled back upon and exteriorly to said edge and reaching beyond the margin of the packet, reaching over said margin and terminating on the face of the packet opposite to that upon which the turned edges are located, substantially as described.

3. An X-ray film packet comprising an outer case consisting of a sheet of impressionable material having narrow edge portions upon each of its sides turned over upon its face to hold the film, one of said edge portions having an integral extension Which is folded into contact with said edge providing a double portion of said turned edge, substantially as described.

4:. An X-ray film packet comprising an outer case consisting of a sheet of impres .sionable material having a narrow edge portion upon each of its sides turned over upon its face to hold the film, an outer cover attached to said edge portions, one of said edge portions having an integral. extension folded thereagainst, providing a double portion of said edge, substantially as described.

5. An X-ray film packet comprising a sheet of impressionable material having narrow edge portions turned over one face to hold the film and one edge portion being doubled and providing a finger piece, substantially as described.

In testimony whereof, I afiix my signature.

SINCLAIR TOUSEY.
