EDWARD '1. GLOVER, OF PORTSMOUTH, VIRGINIA, ASSIGNOR OF ONE-HALF TO ROBERT E. GLOVER, OF PORTSMOUTH, VIRGINLL MEANS FOR EXAMINTNG Application filed October 8,

To all whom it may concern:

Be it known that I, EDWARD T. GLOVER, a citizen of the United States, residing at Portsmouth, in the county of Norfolk and State of Virginia, have invented certain new and useful Improvements in Means for Examining X-Ray Plates and the like, of which the following is a specification.

This invention relates to appliances for the use of physicians, surgeons and others, and has special utility for simplifying and expediting the examination of X-ray plates and the like. These examinations are ordinarily conducted in dark rooms and, so far as I am aware, no appliance has heretofore been proposed which would admit of examinin single plates or groups of plates without tie necessity of flooding the room with light and consequently appreciably heating it much to the annoyance and iscomfort of the operator and to the detriment of the plate or lates the sensitized ploating of which is imnriously afiected by eat.

Objects of the invention areto provide a cabinet to facilitate the examination of single or groups of X-ray plates or to provide for prolonged examination without hazard to the plates or films; to provide a cabinet of the nature indicated embodying a plurality of light boxes arranged in tiers and of graduated dimension; to provide for selectively illuminating individual or groups of boxes; to provide for concentrating t e light directly upon the object to be examined; to provide appropriate means for positioning the plates or films with relation to the source of light; and to provide for a constant circulation of air between the plates and li hts.

Wit such and other objects in view, the nature, characteristic features and scope o the invention will more readily be understood from the following description taken in connection with the accompanying drawings, forming a part hereof, and whereinigure 1 is a perspective view of an X- ray plate inspection cabinet constructed in accordance with my invention.

Fig. 2 is an end view.

Fig. 3 is a vertical sectional view.

Fig. 4 is a longitudinal sectional view.

In the drawings, the numeral 5 represents a supporting stand or table, which may be any suitable stand or table or may form part 'tained by X-RAY rna'ms AND THE LIKE.

of the cabinet 6. The cabinet is a four wall structure with top and bottom and subdivided to rovide a plurality of compartments or lig 1t boxes 7, arranged side by side and in tiers. They are preferably of the knock-down type so that their dimensions may be varied. This is accomplished by the shelves or longitudinal separating members 8 appropriately supported by the end walls 9 and the provision of adjustable partitions 10. The front of the cabinet is inclined from the vertical and is formed of opal glass, or its equivalent, in the form of removable panels 11, which are marginally relongitudinal and upright cleats 12 and 13. The longitudinal cleats may be availed of to support the X-ray plates or films for which purpose they are formed or provided with ribs 14; spaced from the lass anels to accommodate the plates or lms.

ile the arrangement stated aifords a simle means of retaining the plates in position and has been satisfactory in practice, it is obvious that other expedients may be resorted to.

Each of the cells or boxes 7 is provided with a source of light here shown as an electric bulb 15, the conductors whereof extend to a standard 16 and from there to a source of current supply, not shown, and to a panel or switch board 17 mounted on top of the cabinet and within convenient reach. Extending across the panel or switch board are snap switches or buttons 18, progressively numbered, and respectively controlling the illumination of correspondingly numbered cells or boxes. Manifestly there is thus provided a simple and convenient means for selective lig tin and excessive flooding of light is wholly o viated.

Access is had to the cells or boxes from i the rear of the cabinetthrough the medium of downwardly swinging or hinged doors 19. The latter also serve to carry the reflectors 20! the function of which is to direct the light rays to the best advantage through the. glass panels.

An important feature of the invention is the provision of means for protecting the X-ray plates or films from the effects of heat generated in lighting. Referring more particularly to Fig. 4, it will be noted that I have provided a fan casing 21 having an outlet 22 and housing a motorized fan or blower 23. The fan casing has tubular arms or extensions 24, one for each tier of cells. of X-ray plates and the like comprising, in The tubes 24 open into the remote cells and combination, a plurality of light boxes arhave its 25 affording communication with ranged side by side and in tiers a cabinet in the otlizrs. For the purpose of maintaining whlch said boxes are assembled so as to be free circulation of air the cells are vente according to their size. As a matter of including opal glass panels arranged on an choice and convenience the air intakes or inclined plane means for securing the panels vents 26 are shown as formed in the including means for positioning the plates,
