X-BA Y-FILM HOLDER AND 'EXAMI'NING- FRAME/ Application filed February 10, 1923. .Serial No. 618,295.
To all whom it may concern: sheet steel and the lower edge of the casing Be it known that 1, JOHN A. ADLER, a citiis secured to a cast, frame 3 angularin r ss zen of the United States, residing at North section, which is preferably made of brass Milwaukee in the county of Milwaukee and or steel, This frame 3 is formed with an State of Wisconsin, have invented certain upwardly extending flange 12 recessed at 13 new and useful Improvements in X-Rayfor the reception of the wall 2, this wall 2 Film Holders and Examinin Frames, of being held in place in this recess and against which the following is a speci cation, refer the flange 12 by means of the bolts 4.

Opposite to the hinge for the supportin Referrin to these drawings, 1 designates. frame of glass 26 is a sprin latch 27 whic a rectangu ar casing having vertical walls engages over the top of the rame 25 to hold 2. These walls are preferably integral and the g as cl o n up n h ing 1- no may be of any desired hei ht and propor- Immediately beneath the sheet of clear glass tions. This casing is preferably made of 26 there is disposed a sheet of glass 28 which is frosted on itslower face in order that the steel frame 25 thus allowing the two sheets of glass 26' and 28 to be brought in very close proximity to each other and securely hold a film between the sheets for examination. The sheet of glass 28 rests upon a strip of felt packing 30, which in turn rests upon the flanges 31 of a parabolic reflector 32 and acts as a cushion for the glass 28 and also prevents moisture or foreign substances,
such as dust from entering the space below the lass.
T e reflector 32-consists of a thirddimention parabola, as shown most clearly in Fi' ures 2 and 7, which is preferably made of one piece of sheet brass pressed to form a perfect parabola terminating across the corners of the casing, while the sides of the parabola from the line 33 extend directly upward parallel to the side walls of the casmg 1, as at 32*, and then terminate in the flanges 31, as heretofore described. The in terior face of the reflector is silver plated and highly polished to thereby insure efficiency of illumination and to savecurrent, as this construction requires that only one bulb of relatively light watta e and high candle power be used, the re ector acting 'to greatly intensify this candle power. The
' lower wall of the reflector 32 is formed Eli with an opening 34 through which the lamp socket 9 extends. This lamp socket also extends through an opening 34 in the bottom plate 11 and the lamp socket is formed with a shoulder bearing against the center of the reflector; and beyond this shoulder the lamp socket is screw-threaded for the reception of a nut 36 in order to cause the'lamp socket to hold the plate 12 and the reflector clamped securely together and thereby. support the lamp socket rigidly in position.
It will be seen from Figure 4: that the edge of the flange 31 bears against the wall 2 of the casing 1 and that the edge of the packing also bears against this wall, thus preventing the introduction of foreign matter into the space exterior to the reflector. The batteries 7 are of ordinary dry cell form and of suflicient capacity and are secured to the inside of casing 1 by means of straps passing around the body of each battery and then bolted to the wall and bottom of the casing, as shown in Figure 3. Thus in order to replace the worn-out batteries it is only required to raise the cover 25, lift out the glass plate 28, remove the lamp socket 9, lift out the reflector 32 and replace the straps 35, and by reversing these steps the batteries may be readily re laced. While I have illustrated ry batteries disaerate-a posed within the casing for causing the illumination of the lamp 8, I do not wish to be limited to this as an can be used to supply the required current. It is preferable, however, to use the batteries as thus the device may be removed to any desired place in a hospitalor class room or to a place where no other power is obtainable, thus rendering the device other source of power proportion and arrangement of parts may be made without in any way departing from the principle of the invention as defined in the appended claims.
claim:-
1. An X-ray film holder comprising a rectangular casing having a bottom and side walls, a parabolic reflector disposed within the casing at its corners extending up to the top of the frame and between the corners having vertical portions extending to the top-of the frame, said reflector at its upper edge being formed with an outwardly extending flan e bearing at its edge against the side wal s, a strip of packing material resting upon. said flange, frame hinged to the side walls ofthe casing, a glass plate carried by said frame and a second glass plate resting at its margins upon said strip of packing material and so mounted as to permit the two glass plates to come in relatively close proximity to each other when the cover is lowered.
2. An X-ray film holder comprising a rectangular casing having a bottom and side walls, a parabolic reflector disposed within the casing at its corners extending up to the top of the frame and between the corners having vertical portions extending to the top of the frame, said reflector at its upper edge being formed with an outwardly extending flange bearing at itsedge against the side walls, a strip of packing material resting upon said flange and at its side edge bearing against the side walls, a rectangular frame hinged to the side walls of the casing, the framehaving up or and. lower flanges, a glass plate dispose between said flanges, and a second glass plate resting at its mar in upon said strip of packing mate* rial and having the upperface at-its margin bevbled to accommodate the lower flange of said frame whereby to permit the two glass plates to come in relatively close proximity to each other when the cover is lowered.
In testimony whereof I afiix my signature.
