To allfwhomz'tma concern.'

Be it known t at I, ARTHUR W. BUCK, a citizen of the United States, residing at St. Louis, inthe State of Missouri, have injvented certain new 'and useful Improvements in Containers for X Ray Films, of which the following is a specification, reference being had to the accompanying drawhis invention relatesto the art of pho-l tography and more articular-ly to the use of sensitized films which are used for the purpose of making rntgen'oiianunI or, in-

paper packet make it diicult to use'the X-ray photographs of packet for m the-molar teeth. e paper wra per for the film being absorbent, soaks up t e saliva and is thus unsanitary and the packet being of aper pliable but resistant and therefore w81 not retain any curvatureor bend which may be given to it, and, therefore, cannot be 4fitted to the mouth or .teeth The general object. of my invention is to avoid inconveniences of this nature by the provision of packet including a container or envelop whichy is of lightproof material but which is very thin, is not absorbent, and which is made of soft metal 'which is 1mpreionable, thatis, exible or pliable. with.

oughly protects the sheet'than is possible where the sheet iswrapped in photographically opaque paper.

Stilll another object is to provide an envelop of such form that a photo aphic film may be held in close contact 't a metallic back, thereby greatl .addin to the speed and quality of the -ray 'p otograpli.

A further object is to rovide an envelop of such cheap construction that it may be vdiscarded after use, thus avoiding the necessity of sterilizing and reloading a holder after each patient, the envelop, however, be-

4ing so formed as to secure the advantages previously set forth.

Still another object is to so form the envelop within which the film is contained no overlapping of two sheets or thicknesses of metal across the face of the lm .Other .objects will appear in the course of.

the following descri tion.

.My invention is illustrated in the accomp ying drawings, wherein one form of this container is illustrated.

Figure 1 is a face view of my light proc container for photogra hic lms;

Fig. 2 is a rear view t ereof; v

Fg. 3 is a section on the line 3 -3 of modied form of container. It will be seen from these the envelop of my improved es that packet' comprises a thin'metallic back of relatively l v metal, designated 10,

soft impressionable and a front plate designated 11, which mady be made of celluloid or which may be ma e of any other sa-,able material which will be' iightphotogra hically opaque to ordinary rays. Tige marginal edges -of the bac.; 10 are bent over at .12 upon the YVlate of celluloid 11 and bent down ht y so that the celluloid sheet 11 and the ack 'plate 10 are held in close contigui Previous to the bending over of the e e of the plate 410 there is between the plate -10 and the .front plate 11, one or more disks or sheets. of sensitized film, designated 13. Inasmuch as the celluloid 11 is capable of being bent or 4exed, andfinasmuchas the back 10I of the case is made of metal which is pliable but not elastic, it follows that the 4 is a transverse section through a mean to desi case as a whole is bendable and that because of this pliability the case may be bent and will retain its form.

It is to be understood that while I have referred to the sheet or plate 11 as being formed of celluloid, or like material, yet I do not wish to fbe limited to this, as it maybe made of any substance that offers resistance to either light, moisture, or both. I may use paper for the front plate or sheet of the envelop, or I may use any other material which is opaque to ordinary light rays. It is obvious also that it matters not, from an effective standpoint, whether the back clenches over the' front or the front clenches over t e back, or whether, as in Fig. 4, a mere rim of metal'14 is used with a back 10 of celluloid and a front 11a of Celluloid or paper.' In this case the rim A14: will hold the container in proper shape. By the term impressionable as used in the specification and the claims appended, I

ate the quality of being bendable or lexi le and retaining the bend or conformation given to the article.l

I am aware that prior to my invention film holders have been desi ed which are intended to be used for holdin a film within the mouth of a patient. he holder as proposed consists of a dat capsule of material which is not impressionaible in the sense that Vthe material can be bent and will retain the bend given to it and the shape of the capsule or box being such that it could not, as a holder, be bent to conform -to the shape of the mouth except under great pressure.

Furthermore, such ca sule or holder was of such form that if a end were given to it, the container would no longer be light prooi?.

Furthermore, holders of the character above stated have the form of a box, the body of which is open at one end and which ris closed by a sliding cap. The suggested holder `has, a thickness of metal over the front, a certain thickness over the back, but

v at the 'front and the [back there will be an extra thickness caused 'by the overlapping of the cap upon the body of the holder. If the holder is. made of aluminum as thin as .006 of an inch, the two thicknesses at the joint would have a ythickness of .012 of an inch. Furthermore, these carriers, as made,

had a length of 1% and a'width of l". It will be obvious, therefore, that the holder could not be bent as a whole under ordinary pressures, even though the sheet metal might be pliable in itself..` The metal used by me is relatively soft, and inasmuch as there lis only one thickness of this metal, the envelop so formed may be readily bent to conform to the shape of the teeth or mouth, without any breaking of the joints.

Furthermore, the margin of the metal the film into contact withthe metallic back is forced down tightly-upon the cellu- `loid front so that the inclosd lm is held j is designed to be thrown away and not to be used a second time.

it is to be understood that while I have' illustrated in the drawings only one disk or sheet of sensitized film disposed within my container that ordinarily two pieces or disks of film are usually disposed within the container and that it is within my invention, of course,'to use either one piece of film, or a lurality of pieces, as found desirable. Furt ermore it is to be understood that by the term photographic lm as used in the specification and claims, I wish to include any thin sheet of photograpbically sensitive material.

-Having described my invention, what I claim is 1. An X-ray film packet includin an envelop having a front and a back, t e front being of thin flexible material photographically opaque to visible rays, but permeable by invisible rays, the back being of soft impressionable metal, and a photographic lm disposed between the back and front.

2.

e. An X-ray film packet comprising a back and front formed of flexible material, both the back and front being photographically impervious, to visible rays, the front being permeable iby invisible rays, and a photographic film disposed between the front and back, the back being connected to the front by a band of soft, impressionable metal, whereby the packet as a.whoie may be forced to take a desired ycurvature and will retain this curvature..
