2 Claims.

This invention relates to improvements in daylight fluoroscopes.

The primary object of my invention is the provision of apparatus by means of which an X-ray image depicted upon a fluorescent screen can be transmitted to any desired source, near or remote, and designated upon a screen from which it may be photographed or viewed in ordinary light.

With present X-ray and fluoroscopic screen apparatus the image is designated upon the fluorescent screen and is generally viewed from a dark room by an operator who becomes accustomed to the darkness of the room after or minutes, so that the image can be properly viewed. With my improved apparatus I am able to designate with X-ray equipment an image upon a fluorescent screen, upon which an iconoscope of a television transmitting set is directed, so that the image can be transmitted to a remotely positioned television receiving set; the kinescope thereof designating the image upon a viewing screen, from which it may be readily seen under varying light conditions, and from which it may be filmed.

A further object of this invention is the provision of improved apparatus for adjustably supporting a fluorescent X-ray receiving screen and its associated television transmitting apparatus.

Other objects and advantages of this invention will be apparent during the course of the following detailed description.

In the accompanying drawing, forming a part of this specification, and wherein similar reference characters designate corresponding parts throughout the several views, I

Figure 1 is a view, partly diagrammatic and partly in section, showing the associated apparatus of my improved invention.

Figure 2 is a, view taken substantially onv the line 22 of Figure 1, with the supporting stand of my improved apparatus in a differently adjusted position than that shown in Figure 1.

In the drawing, the letter A may generally designate an X-ray tube of suitable X-ray apparatus from which Roentgen rays are emitted for passage through a body for transmission of an image upon a fluorescent screen B. The latter is supported as a unit with television transmission set C, operatively connected by means D (well known in the art) with a television receiving set E. The latter has associated therewith a glass screen F, preferably a magnifying fluorescent lens of low power very thinly coated and allowing light to pass therethru and at the able base 3la.

same time fluoresce' proper manner. Improved means G is provided for supportin in an adjustable relation the unitary association of the screen B and television transmitting set C. The transmitting et C is of Well known constructio'fi, and need not be furthei'freferred to.

than to say that it has associated therewith, an iconoscope ll] facing the image upon the findrescent screen B; a case I I supporting the same therein, and detachably receiving also the flucrescent screen B. The latter is held upon the case by means of releasing clips I2.

The television receiving set E is likewise of well-known construction and includes a kinescope. A suitable cabinet or casing l5 receives the television receiving set E and supports thereupon a screen F detachably held in position by clips 16, similar to the fluorescent screen B. Thus, it is seen that the fluorescent screen 13 and television transmitting set C are associated as a unit, and likewise the television receiving set E comprises another remotely positioned unit. These television sets are operatively connected in conventional manner by the means D which includes a coaxial cable.

Referring to the means G, the same may be of any approved construction. However, it is preferably of a nature which permits of adjustment of the fluorescent screen and its television transmitting set C so as to properly position it with respect to the body, the image of which is to be designated upon the fluorescent screen. In case the transmitting set C does not have a unitary connection with the fluorescent screen B an adjustable mounting similar to the conventional fluorescent screen may be provided.

The means G preferably consists of a supporting standard 30 mounted upon a preferably port- An elongated supporting case 3| is rotatably mounted by means of a stub shaft 32 upon the standard 35); said stub shaft 32 having an anti-friction bearing 34, and an adjustable step bearing 35, which cooperates in supporting the casing 3| vertically, horizontally, or at an acute angle to the vertical or horizontal. The casing 31 is provided with rollers 40 and 4| at its ends, around which cables 42 and 43 respectively are trained. The cables 42 and 43 are connected at adjacent ends by means of a counter weight ,44 and at their opposite ends support a member 45, having a tubular extension 41, upon which the fluorescent screen and television transmitting set unit is mounted. This tubular portion 41 projects through a slot in the casing 3 I, so that it may slide along said slot.

The casing ll of the fluorescent screen and television transmitting set unit has a stub extension 5| connected therewith terminating in a ball 52 which is socketed at 53 in a rod or support 54 telescoped in the tube 41.

With the above mounting of the fluorescent screen and television transmitting set unit, it is possible thru the ball and socket connection 5Z53 to angularly or forwardly position the screen. With the telescopic tube connection 41-54 it is possible to forwardly and rearwardly move this unit with respect; to the-stand 3i. Set screws 60 and 6| are provided for locking the ball and socket connection, and the telescopic tube connection respectively. Similarly, a set screw or knob 64 is provided for locking the stub shaft 32 against rotation at the anti-friction bearing means 34.

The receiving set and viewing screen unit may be mounted upon the top of the standard 30 or at any other approved location. The operation of the device will be apparent from the foregoing. It is possible to vertically, horizontally, or angularly position the casing 3|, so that the fluorescent screen and its associated television transmitting set may be adjusted in any desired position, for purposes well known to those skilled in the art.

The casing ll preferably has several lights therein, the circuit therefor including a rheostat 8| so that the intensity of illumination may be varied.

Various changes in the shape, size and arrangement of parts of the invention may be made to those shown in the drawing Without departing from the spirit of the invention or scope of the claims.

I claim:

1. Apparatus for the transmission of X-ray images and the like comprising a supporting base, a member rotatably mounted on the supporting base, a fluorescent screen mounted for rotary movement with said member, and means for sliding said fluorescent screen across said rotary member to either side of its axis of rotation.

2. Apparatus for the transmission of X-ray images and the like comprising a fluorescent screen, a supporting base, and means mounting the fluorescent screen on the supporting base for upright and transverse adjustment to suit the position of a subject to be reflected upon the screen, and means independent of the aforesaid adjusting means to further adjust the screen universally.

EDWARD E. WILLIAMS.
