PORTABLE X-BAY vrnw ne Box.

Application filed December-13,1924. Serial No. 765,666.

My invention relates to viewing boxes for X-ray negatives, and the object of my invention is to produce an efiicient, simple and easily portable Xray viewing box which may be quickly prepared for use, and may be illuminated by plugging in on any usual electric light circuit. A

The manner in which I accomplish my object is illustrated in the accompanying drawings, in which:

Fig. 1. is a vertical cross section through my improved portable X-ray viewing box when set up ready for use, the protective cover plate being removed.

Fig. 2 is a similarview showing the device folded and the cover plate in place.

Fig. 3 is a plan of the folding reflector which forms a part of my improved device.

Fig. 4 is a top plan view of my device when set up as in Fig. 1.

The same reference characters refer to.

the sameparts throughout the several views.

It is to be understood that the drawings are in a certain sense illustrative only, and that many changes may be made in the device withoutdeparting from the spirit of this invention. For instance, the reflector may be hingedly attached togthe tray like portion or base of the device if desired.

- Referring to the drawings, B is the traylike back which forms the supporting base of the device when set up as 1n Fi 1, and which is designed to contain the 0 din reflector B, when the device is fold or packed as in Fig. 2.

Attached to t e base B by means of suitframe like member F, the openmg through which is-closed by a translucent material, such as ground glass, G, upon which the picture to be viewed is to be laid. Beneath, part G, is a sheet of semi-transparent material, such as tracing cloth, T. A protecting cover plate C, adapted to protect the part G from accidental damage when the device is not in use, is detachably fastened in the frame F in any suitable manner, here illustrated as by the dowel d, and a spring bolt 85.

The ends-of a substantially U-shaped supportin bracket U are 1pivotally secured to the si es of the frame and the cross-bar U of the bracket, fitting into suitable illustrated. A

of the carrying and spaced from the ,the light which emanatesfrom notches in the sides of the base B, holds the frame Fin proper angular elevation with reference to the base B. (See Fig. 1.) The cross-bar U also provides a support for a lamp socket S, adapted to receive a lamp 17, adapted to illuminate the interior of the box. I prefer to use a daylight lamp for this purpose, and the bracket should be so proportioned, and the socket so located on the cross arm thereof that the lamp when in place therein will be on aline with the center of the opening through the frame F, when the device is set up ready for use.

A length of cable is attached to the socket, and in this cable is preferably incorporated a suitable switch and plug whereby the same may be connected to-any usual lamp socket and the circuit controlled. These parts being standard and this general arrangement universal, they have not been shown.

The manner in which m device is packed when dismounted is clear y shown in Fig. 2 of the drawings. Before packing the de' vice the lamp is to be removed from the socket, the reflector is than folded and laced in the tray-like base B, and the brac et U swung up and the parts folded together as storage place for the lamp and the necessary cord, switch, plug and so forth, is provided by attachi at the sides handle H which is located at the center of the end of the frame F, a box or boxes T.

Some suitable means, staple, are provided for B and F in closed A device of this kind constructed sub stantially as illustrated and described, is quite sim 1e and readily portable. The placing o the lam substantially central with the frame an providing a reflector which will concentrate practically all of the lamp directly against or through the, semi-transparent member T and the translucent member G, insures the elficient illumination of all parts of a plate placed u on the member G to be viewed. The use 0 daylight lamps as the source of light, a ground glass as a base for the plate to be viewed to rest on, and a semi-transparent curtain between the lamp and the ground glass, produces an aprelation to each other.
