nite position and to enable the operator ob" taining the necessary adjustment moving the patient to the desired position with ease and .adjusting theplate' holder to the required position.

A further object is to enable the operator to denitely locate the position of the plate in relation to the patient and the particular portion ofthe anatomy to be photoconsists in the novel construction `and arrangement of parts, whereby a locating frame is slidably adjustable upon a supplementary frame adapted to be placed upon the operating table, said slidable frame being adapted to receive andsupport the body of the patient in a definite position, and whereby the: plate' holder is adapted to be adjusted longitudinally and ltransversely without interfering with or moving the patient.

A further feature `consists in the novel arrangement of an opaque member upon the plate holder whereby the adjustable plate holder is definitely located.

In the drawings, Figure 1 is a perspective view of a device constructed in accord ance with this invention, a portion of the holder for locating the patient being broken away.

Fig. 2 is a longitudinal mid-.sectional vieu through the device.

The device shown inthe accompanying drawings illustrates a structure adapted to be used on the ordinary X-ray operating table and it comprises a rectangular frame 1 provided with hooks 2 to be hooked over one end of the table to hold it in place. The side rails Bare formed with the longitudinal dove-tail grooves 4t extending from end to end `thereof. The rectangular frame 5 rests upon the frame' 1 and is provided with dovetail tongues 6 extending longitudinaliy of the side rails and fitting the groot/*es 111 beA ing slidable therein. t. Y

The outer edge of one of the longitudinal members of the frame 5 is providedlwith the metallic toothed rack 7 which extends from end to end. rhis rack is engaged by a re- 'tat-able latch member 8 piif'otaliy secured to the side rail 3 of the 'frame 1 at a convenient point and said latch member is adapted to engage the rack to hold the frame in any desirable adjustment as it is moved lou: gitudinally in its grooved support.

The inside edges 9 of the longitiulinal.

members of the frame 5 are formed with the rabbeted grooves 10 and between these sides is slidably arranged a frame 11.

A pair of transversely arranged bars 12 and'13 are secured to the frame 11 and e1;- tend over the 'top faces of the side bars of the frame 5 and each is provided with ati-abbet tongue lei to receive the transversely slidable member l5. i

The lower bar 13 is of greater width than the thickness of the member 15 and forms a ledge 16 against which the photographic plate liolderislaid.

The slidable member 15 is provided with an end strip 17 against which the end of the plate holder is located and the inember 15 is provided with a handle 18 at the front end by which the member is operated transversely in its guides. f

The frame 11 is secured in adjusted positions longitudinally of the frame 5 by means of a ratchet dog 19 rigidly secured to one end of the bar 13 and engaging a toothed metal rack 20 bedded 'in a Ylongitudinal groove 2&1 in one of the side members ofthe frame The member i5 has embedded in one side thereof a metal ring 22 which is used for the purpose of locating the proper position .of the plate. in relation to the patient. The

center of said ring is arranged to coincide with the center of a photographic plate when the holder is placed against the bar 13 and against the end strip 17 of the mema bridge structure formed by a strip 23 of canvas or leather stretched between the brace members 24 and 25 rigidly secured to theyframe 5. A head support 26 -is arranged beyond the member 24e andbeyond be readily altere be repeated continuously for suitable 3e- A made of Wood and the member 25 is arranged a knee or leg support.'

The member 23 is of concaved formation i adapted to form a comfortable restfor the bod of the patient.

j and grips 27 are secured to either side of the brace member 24 to enable the patients steadying themselves or to shift their position.

The device may be used in a vertical position or may of cou-rse be tilted at any angle as maybe desired bythevoperating physician; The position of the patient may by sliding the frame 5 on the `frame 1 andthe plate holding trame 11 is Vadjusted in the longitudinal' grooves in the frame 5 until the slide member 15 is brought to the desired position, the same being located in relation to any portion of the antomy which it is desired to have centered upon the plate. When located the frame 11 is locked by means of the ratchet 19 and the operator places the plates upon the slide member 15 which may be moved .inwardly close to the patient and again moved outwardly in order to `quickly recover-the plate holder. This operation may riods in obtaining a series of plates in 'ollowing the action or" the internal organs. The device is extremely simple, is preferably is light and easy to handle. Y A

The concaved form ot' the member :23 is ofvery great importance as it conforms to the curvature of the body and maintains the organs in their natural position.

What l, claim as my invention isa-1 1. ln an X-ray photographing appliance, the combination with the operating table, of a traine longitudinally adjustable upon the table and adapted to support the patient, and a plate holding member supportedon said adjustabley frame and longitudinally and transversely adjustable vinfrelation to said frame. v

2. Inan vX-ray photographing appliance,

v4the combination with the operating table, of

a base frame adapted to be secured to the table and having longitudinal guides, a trarne longitudinally slidable upon said guides for supporting the patient, means for holding said frame in adjrnstedI positions, and a plate holder supported uponv the ad justable frame and adapted to. be adjusted longitudinally and transversely independent l of said su porting frame;

3. AnA T-ray photographing appliance,

,aan

comprising a rectangular shaped base adapted to be placed upon an operating table and having longitudinal dove tail grooves extending i'ro'm end to end thereof, a rectangular traine f having dove tailtongues slidably engaging 'the grooves in the aforesaid trame, a toothed rack secured to thebase frame, a ratchet member carried on the movabley frame and engaging said rack to hold it in adjusted positlons, a body supporting structure secured to the latter` frame and spaced therefrom, and a plate holder arranged between said supporting structure and the trame and adjustable transversel and longitudinally.

l. An I -ray photographing appliance,

saidlongitudinal guidevvay and having a` pair of transverse guides, a toothed rack arranged upon the supporting frame, a
