( deans, in the parish of 'f rleans and State l Louisiana, have inverted certain new and useful Improvements in lx1-Ray Apparatus; and l do hereby7 declare the 'following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it. apperlains to malte and use the same.

My invention relates to lili-ay apparatus, and has 'for its object vthe production of an improved trarne supporting said apparatus which is capable oi being slid along and moved in front of the' patient, and when not in use can be pushed to one side. l

A further object the invention is to provide such a traine that` will not necessitate the patient to be moved, and which vvill enable a fluorescent screen to be moved over hiin for the purpose of making cxaminations of different parts or the body.

Vivith these and other objects in view the invention consists in the novel details of construction and combinations of parts more fully hereinafter described and particularly pointed out in the claims'.

Referring to the accompanying drawings forming a part of this specification in which.

like numerals referto' like parts in'all theI views-Figure l is a perspective view of the improved apparatus which may be either supported from the floor or from a table; Fig. Q is an elevational View of the X-ray frame-holding parts proper; Figs 3 and l are detailed views of different portions of the apparatus. Fig. 5 is ai perspective view of the X-ray tubeholding bon and its attechrnents, and Fig. il and 7 vare sectional diagrammatic views showing the operation of certain of the attachments.

l indicates the uprights of e main frame, preferably rectangular in shape, provided with the upper track 3 and lower track i ou which the sliding trame 5 moves.

The main frame is preferably supported upon an operating table, but, of course, may be supported from the door or other suitable surface. l

The slidingr frame is prfwided-'with the uprights il, which, at their upper ends have the sliding extensions 7 secured to the uprights (3 the clamps 8 and which are provided at their upper ends by the cross piece 9. The cross piece is suitably provided by ineans of" the cords or other with. the rollers or other anti-friction devices l0 engaging the upper track of the main frame as illustrated.l r-`he lower ends of the uprights 6 carry the cross piece il, which is likewise suitably provided With rollers or other anti-friction devices l1 which engage the lower track 'fi- .oii the main frame. 1Within the uprights (S is slidingly litted suitable frame 113 to which is attached the bracket iet, accommodating thescrevv l5, carrying:` at its lower end the bevel pinion '1.6, engaging a similar lpinion i7 on the horizontal shaft 18, which at its outer end carries the pinion 1S) engaging r, similar pinion 2O on the shaft 2l, carrying `at its upper end the pinion 22 engaging the pinion 25?, which is operated by the hand lever 2d.

.The lower end of the screw l5 is sup l supports the gears or pinions it), 20, and

23. rlhe slioingofraine 1:3 also carries the, slotted braclret@ in which lits the thumb screwY lattached' to the rectangular frame 32, the inner end of which 4is secured to said sliding frame 13, as shown. i

ln the frame 32 ts the lead llined boaA 83 which carries the X-ray tube. The bracket 3l, sector 35 and thumb screw 3G afford an angular adjusting ineens for said box, which hss its pivot on the trunnion 157. Said box is provi-ded with an iris diaphragm 38 prei erably ot' lead controlled by the lever 39, inside ot' which are the slide pieces 40,' as nbest seenin Fig. Said box is also provided 'with the lead glass Window el, theremov able cover 42 and the openings eri to accommodate the supports for the X-ray tube. 4-3 represents the lead lining of. the box The X-ray tube is preferably mounted on a screiv-controlled carriage inside the boX, not shown, so that the saine may be adjusted longitudinallyY as well as transversely of its anis.

'The uprights 6 carry the projecting pieces 45 which support the iuorescent screen 46 attachments 4i?, to the ends of which are secured the weights 48, as best seen iu Figs. Q and 3.- The cords 47 preferably' pass inside the pieces 4I, and are conveniently accommodated behind the uprights 6. 4:9 represents pulleys over which the said cords pass.

50 represents a suitable cam lever attached i to the cross ieee 11 and which` serves to jam 1 the sliding rame 5 between its tracks 3 and fi, and thereby'to secure the X-ray tube and lts'co-acting parts in any position to-which the'frame 45 might have been, a'd'justed. It

is often very rde'sirable'to'find the central rays emitted from the cathode, and to this end I have provided the box-like frame 55 rovided with a double set of cross wires dicated in Fig. 6. By

. of rays emitted by the cathode` he is using.l

The frame.58 carryingthe outer center 57 is slidably removable from thebox1ike frame 55 as shown, and, therefore, when only .a single cross wire is desired, said frame may be taken away, and onlythe single wires 56 `employed. yIt is also sometimes desirable to cut oi all of the rays eX- cept those emerging from a particular portion-of the pencil emitted from the cathode, and to this end I have provided what I terln 'l a compression cylinder'O, which is provided with a lead lining 61, and which slidingly fits. the pieces 40 on the box 33 so as to come opposite the center of the iris diapwhragm as dilagrammatically indicated in ig. 7.' With this attachment, if -th'e center 4'of' the tube 60 is opposite the center of the cathodethe central rays will be utilized, as indicated, but if the X-ray tube 62 is adjusted by any suitable means, then any other portion of the pencil 63 `may be emitted through said compression cylinder 60. yThis compression cylinder is'v found to be exceedingly useful insciagraphic work, and by its means the secondary `rays rmay be entirely eliminated, and when necessary a very firm compression of :the pencil, soto'speak, may be secured.

It often happens that, in treating diseased surfaces of 'various sizes, the patient be comes burned Vat points'other than those intendedto be treated, and therefore it is de-l sirable to provide a shield holder to confine the rays to the-exact spots intended to be acted upon. ,To these ends I have provided 'the plates 65 having a tubular attachment 66 provided with the clamp screw 67 and theflead lining 68. This plate 65 adjustably ts the channel pieces-40, andthe tubular projection 66 readily accommodates lead glass shields .which need not be m'orethan two inches in length, and a half inch to two inches in diameter at the free end. It is also echec? often desirable to provide some means for centering the X-ray tube over a given point Aof the patient, of the photographic plate, or over the iuorescent screen. To these ends I have provided the centering plate 70 have ing the lead lining 7 and the twoperforations 72 and 75 through which passes the cord 73 to which is attaehedthe weight 74. The plate 70 likewise lits the channel pieces 4:0', and the plumb weight 74 is adapted to reach down to' any given point. over the patient, photographic plate or liuorescent screen.' The orifice 75 through which the weight end of the cord passes, being exactly Vopposite the center of the iris'diaphragm, the weight 74 will naturally locate the exact center desired, and therefore the path of the central rays emitted-from vthe X-ray tube.

The operation of the device will be clear from the foregoing, but may be briefly summarized as follows :mWhe'n it is desired to use the'X-rays, the uprights 6-6 are adj usted along the tracks 3 and 4 until the box` 33 'comes about opposite the point on which it is desired tofocus'the X-rays. The frame 32, which may be normally folded up out of the way by means of the bracket 30 and.

thumb screw 3l, is let down into the horizontal position shown in Fig. l, and thel X-'ray tube is adjusted until it is thought that itis in about the right position for use. To determine the exact position the fluorescent screen 46 -may be pulled down and placed opposite the iris diaphragm, when, it the rays are turned on, the approximate position will be indicated. In order to get the prope` focus the hand lever 24 may be operated so as the X- ray tube up and down, until the proper focus is attained. In case the angle of the `rays is not just right, the box may be to adjust the box 33', and with it n -angularly ad'usted on its trunnion 35 untilv theraysreacl the right spot.

" rAfter `the center of the iris diaphragm is inline" Withthe center of the spot to be operated-upon, then the center of the pencil of rays' emitted from the cathodemay be determined by placing the box like frame 55 in thechannel pieces 40 and noting 'when the centers 57 makesubstantially aA single shadow. If they do not make a single *shadow the `X-ray 'tube itself is then adjusted in the box 33 until substantially a single` shadow is observed. Or if it is not desired to" get the exact center, the approximate center, either of the central portlon of.

. the, rays or of any other portion, maybevatf.

tainedfby removing the slide 58 of the box# like framel 55 and using only a single center 57; Y*

If only a portion of the central rays are desired vto be used, or in other Words if the said rays are desired tobe compressed, so to speak, then the compression tube 60`is employed. When treating diseased surfaces of employed. ln all cases the iiuorescent screen cerco? 'parts of said surfaces, then the shield plate 65 is used. When it is desired to locate the exact center of the diaphragm over a particular point of the patient, before the rays are turned on, then the centering plate TO is may be brought in front of the iris diaphragrn and used, or if desired the box may e unclamped from the screw and swungon its axis through 90o and the fluorescent screen 46 used in the usual way, with the rays projected in a horizontal direction.

Of course I do not 'Wish to be limited to the exact details of construction and arrangements of parts above disclosed, except as may be rendered necessary by the claims, for it is evident that my device may be varied by those skilled in the art Without departing from the spirit of my invention.
