PATENT, OFFICE X-RAY TABLE Rhea D. Cass, Lakewood, Ohio Application November 29, 1932, Serial No. 644,869 Y Claims. (Cl. Z50-34) This invention relates to a portable table especially adapted for use in connection with the taking of anatomical X-ray pictures, having for one of its objects a novel construction which 5 enables the ready photographing of any part of the anatomy of a subject placed upon the table. The table of this invention is designed especially for veterinary use, although it is not to be regarded as being necessarily so restricted. However, in veterinary operations, the nature of the subject may render its positioning for the desired pictures a more or less difficult operation. This is especially true where the animal is large, it being sometimes difcult to hold the animal in ,15 position for the taking of the pictures, and to graphed, These securing instrumentalities consist of straps suitably secured to carriers which are arranged to be adjustable in guides disposed along the sides of the table. As many vof these guides may be provided as may be necessary to secure subjects of different sizes in position,

and as many of the straps may be employed as needed to iirmly secure all parts of the anatomy of the subject against movement, so that the legs and body thereof lare rmly restrained against the table.

The invention further contemplates the provision of instrumentalities whereby the films may be disposed beneath the table in such a manner'that any part of the anatomy may be photographed while enabling various sizes of Yfilms to be employed, depending upon the part of the body tobe pictured.

For accomplishing this, the table is provided with a plurality of film receiving compartments, which may be simply drawer-like receptacles or trays slidably mounted within the frame of the table and so dispo-sed beneath the surface of the table as to be adjacent any part of the subject to be pictured, the desired lm being simply laid in the desired position in these compartments.

In addition toits use as an X-ray table, the present construction may be so formed as to serve as an operating table, or'for use in animal experimentation for anatomical demonstrations in vivo-as well as for post-mortem work.

While the invention is illustrated as being used in connection with veterinary work, and will be so described in the following description, it is to be understood that the use of the table is not solimited,y as obviously it may be employed for X-ray and operating purposes on human sub-y jects as well as animal without substantial valter` ation lof the construction of the table.

The accompanying drawing illustrates a convenient form of Vconstruction of the'improved table, in which drawing l. j

Referring to the drawing, the body ofv the table is indicated as l which is supported by legs 2, which are mounted on wheels 3. The table is provided with the operating surface 4, in which are provided the grooves lor slots 5 in which4 are positioned the carrying members 6 for the securing strap '7.

One of the features of the invention includes Alll() the positioning of these guide slots, and the shape of the slots. It will be observed that as many of these slots may be provided for the accommodation of a subject of any size as may be desired for the suitable positioning of the subject on the table. In the drawing, it will be seen that one of these slots extends along each long side of the table, and intermediate these slots, other longitudinally extending slots may vbe provided. In the form shown, themcre widely separated slots are employed for securing larger sized subjects to the table, whereas the smaller sized subjects are accommodated by -the more closely positioned slots. in each instance, and, therefore, only one need be described in detail.

Each slot is substantially square-cut and is provided'with over-hanging flanges 8 which retain the strap carrier members 6 in position in the slot without possibility of accidental displacement therefrom. 'I'he carrier members 6 are of a size. which enables the carrier members to slide freely within the slot, the upstanding lug 9 of which members extends between the aforesaid guide flanges, so that the strap 7 may be readily secured, by instrumentalities hereinafter to Abe mentioned, to these carrier members. Y

. .The slots 5` are provided atsuitable intervals therealong with transverse slots' 10 of the same cross-sectional shape as the slots 5, and of the same cross-sectional area as the Slots 5, and the flanges 8 terminate short of one end of theslots 5 to enable the strap carriers 6 to beinserted in the slots 5. This provides vthe slots 5 with an enlarged end, indicated at 11.

The strap carriers are adapted to t snugly between the sidesk of the slots, and are proportioned sothat they may be moved into the transverse slots 10 when it is desired to interlock the strap carriers in proper adjusted position so that they will be secured against'accidental displacement from their adjusted position.

For securing the straps 7 to these carriers, each carrierv is provided with an eye-12 adapted to receive a snap hook 13 secured to theends of the strap '7. z

.Each strap is formed of two sections, joinable by the buckle 14 in the well understood manner. The manner in which the straps are employed and the adjustment thereof are clearlyl shown in Figure 2, and it is believed that no further description of this phase of the invention will be required.

For taking the X-ray pictures, asuitablenumber of film receiving trays are employed, which .are indicatedv at 14d, and which are disposed beneath the operating surface of the table so as to receive film in such manner that any desired portion of the subject may be photographed. These trays 14a are simply shallow drawer-like receptacles, sl'idably mounted in the table and provided with a handle 15 by means of which the trays may be withdrawn and inserted relatively to thetable.` It will be apparent that film of any desired size may be employed in these trays, depending upon the portion of the subject to be photographed.

When it is desired to use the table as an operating table, it is provided with drains 16 extending around the margins of the table, and communieating with a receptacle-17 through drain ropen- .ings- 18, the receptacle being positioned on a support 19.

In order to facilitate the handling of the table, it may be provided with brake instrumentalities 20 of any standard type,`so vthat the table may be However, these slots are of similar shape more readily stopped when it is being moved from place to place.

It will therefore be seen that in order to examine the specimen, which may be designated as A, it is placed upon the table and the straps adjusted by sliding the carrier blocks 6 along the respective grooves .5 until the straps are in proper position for strapping down the respective part of the subject. The carrier blocks are then interlocked by slipping them into the transverse slots 10, thereby holding the blocks in required position. The `ends of the straps are then brought over the portion of the subject to be secured, and strapped together sufliciently tightly to hold the subject against moving. Inthis manner the legs, body,

and head may thus be held against movement.

The X-ray-lamp may then be adjusted to the desired position without'diiculty, and the lms arranged within the trays 14a so as to photograph whatever portion of the subject which may be desired to be pictured. Where itis desired to use the table for operating purposes, the subject is secured in position in a similar manner, fluids from the operation being removed through the drains 16 and thence into the receptacle 17.

-.Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is-
