X-RAY-F ILM CARRIER.

Specification of Letters-Patent.

Patented Mar. 8, 19?].

Application filed February 15, 1919. Serial No. 277,271.

To allwhomz'tmay concern:

Be it known that I, SINCLAIR ToUsnY, a citizen of the United States, resident of Brooklyn, New York, have invented certain new and useful Improvements in X-R ay- Film Carriers, of which the following is a specification. a

In the work entitled Medical Electrzczty Rontgen Rays, and Radium, second ed1t1on,

ublished by W. B. Saunders Company, fihiladelphia and London, 1915, pages 862 and 863, there is described a vertical filmcarrier for use in the mouth of the patient and consisting generally of a thln aluminum caseto receive the film, havlng a closing member in the form of a cap which fits over the end of the case. My present invention is an improvement upon this film carrler.

It is desirable to provide means whereb an X-ray film carrier may be removed rea ily from the patients mouth without handling the carrier itself, covered as 1t may be with infected saliva and further it is desirable to provide means whereby the carrier may be opened, when withdrawn from the mouth, without, requiring the operator to use-his fingers in rupturing the enveloping member or -laying back any portion thereof by direct contact of the fingers therewith and furthermore it is of advantage to have means whereby, in case the carrier accidentall becomes lodged in the throat or back of t e ily dislodged and drawn away.

The invention. consists in the features hereinafter described and particularly pointed out in the claims.

in the drawings:

Figure 1 is a rear invention. A

Fig. 2 is a front view.

Fig. 3 is a sectional view.

Fig. 4 is a rear view of another form.

Fig. 5 is a View of the blank from which the form of Fig. 4 is made.

Fig. 6 is a sectional view line 6-45.

The film carrier is made of thin soft metal such as aluminum andv has an edge flange 1 turned over upon itself at the rear face to hold a back late or sheet 2 also preferabl of thin sof t metal, wlth the film 3 and a s eet of black paper 4 inclosed between the front and back. The front of the member which has the flange 1 is transview of one form of the arent to the X-ray and thus a large field mouth, it may be readsimply laid in at the of exposure is presented by taking the picture through this front wall.

11 order to provide means for enabling the operator to maintain some control of the carrier while in the mouth; to enable him to withdraw the carrier from the mouth without direct contact of his fingers therewith and to enable him to readily open the carrier, while avoiding manipulation thereof by the fingers directly, I provide a flexible member of string form 5 which is laid under the flange and against the wall where the flange is turned, said member having a rojecting end or ends of any desired ength, for instance such that they will project outside the mouth of the patient and will not become covered or saturated with saliva which might be infected. After exposure of the film the operator by taking hold of the dry protruding ends of the flexible member may withdraw the carrier from the mouth and then by pulling upon the said member the flangemay be ripped off to the desired extent or turned back so that access may be had to the film for its withdrawal and development. In doin' this the operator may pull uponboth en s of the flexible member or string and at no time need his fingers contact with the carrier itself. 7 The operation may be performed quickly and with entire safety to the operator.

If the device became lodged in the patients throat it may be dislodged by pulling upon the string.

he form shown in Figs.

i, 5 and 6 consists of a back and front member in one piece, the back being folded over upon the rear face of the front portion and the edges of the latter being turned over the edge of the back at three sides to hold it in place.

The flexible member 5 in this instance is oint where the blank 1s creased in foldin tiie backand tions as shown in igs. 4 and. 6.

This flexible member does not extend approximately entirely around the device as 1n ig. 1 but only along the edge where the metal is folded. This form presents all the advantages above enumerated that is possessed by the first form. It may be opened by pulling the ends of the string in opposite directions while the device is suitably held or by pulling upon one end. In either case the carrier will be opened from side to side and the film may be withdrawn readily.

front por- I do not limit myself to any particular length of'the string as some one of the advantages above'mentioned is resent in any case in connection with an -ray filmcarrier for use in the mouth for even should the string be short a sufiiciently long protruding end or ends would be available to enable the device to be readily opened without danger to the operator. 1

I claim:

1. An X-ray film carrier of impressionable metal for use in the mouth, having a portion turned over upon itself and a flexible member laid within the edge and having a protruding end for opening the carrier.

2. An X-ray able metal for use in the mouth, having a front and a back wall in one piece folded to lie face to face and with the edge of one turned over upon the face of the other, and a flexible member lying within the edge when the piece is folded, and protruding therefrom, substantially as described.

In testimony whereof I aflix my signature.

SINCLAIR TOUSEY.
