therein forshiftable endWise-movement, the con ventional bucky, whereby the bucky maintains its relative-position with respect to the-table top regardless of whether the table top is in the horizontal or vertical I position.

A further object of the inventionresides-ina novel construction of "table havinga hinged-foot section that may be swung downwardly when the table is to be used-for vaginal examinations, with the upper endof the depending footsection serving as asupport for examination instruments orthe like, with brace means-to rigidly position the foot sectionin the upperor-horizontalposition.

Another objectof the invention residesin the novel means whereby the bucky is mounted within the verticallyshiftabletable top-to be adjusted to a desirable point within thetop' for-proper positioning beneatha patient for X ray' pictures or for proper positioningas to height, when the table top is swung to a vertical position-for use in fluoroscopic examinations; with novel "means whereby. the bucky is guided in its --traverse of the table and suitably balanced to maintain'its position of adjustment.

. Other objects and advantages and novel features of construction and operation-will be readily apparent during the course of the following description, reference being had to the accompanying drawings, wherein has been illustrateda preferred form of the invention and whereinlike characters of reference denote like parts throughout the severalfigures- In the drawings:

Referring specifically to theydrawings, the device comprises a fixed table 5, generally rectangular in top plan, having a cover 6 and corner supporting legs 1. The table may be of any suitable constructionand'the legs are of 'a length 'tosupport a tabletopat the proper height.

Hinged to the forward upper end of-thetable- 5, as at 8, is'a box-liketable ton-9; havinga-width equal to the width of the table 5. The top fi'is adapted to-normally lie flat uponthe table 5 with" one end fiush with the end of the table and its opposite end extended beyond the table and its; point of *hinging. The extended end of the top dis-provided with an arcuate bracket iflithat slidably engages aclamp II; fixed to one leg 'l,

through the medium, ofwvhich' the top u'may be securely held against swinging movement, when adjusted to the vertical position, as, shown in Figure 2. Thenormalweight of the top 9 will maintain the topin the horizontal ;position,. as shown in-Figu1-e-1. Hinged to the extended end of the top-9,- as at l2,-isa-pb'ox-like foot section I 3, equal "tothe top Bras; to-- height and width. The foot sectionl3-is normally held in align-5 ment with the-top 9; by a-brace rod M, having shiftable notched-=engagement with a suitable bracket 'carriedbythe legl: The foot section [3' may be dropped down-to the dotted line position shown in-Figures land- 5; by disengaging the brace! 4- and, when-the foot section is in the lowered position, presents :a flat,-relatively wide end, thatserves as a restfor various instruments employed 1 during any examination.

The top-9, beingof box form,'provides an inner compartment It, for housing a conventional.

bucky; The compartment extends for the major length and width of the-to -aandis formed open When the tabletop 9 is to be swung to th'evertical position,

may be found desirable.

along one side, as at ll. The opposite side and ends of the top are fully closed. Rigidly positioned along the sides of the top 9, adjacent the top cover, is a pair of parallel trackways l8, parallel with the top of the top 9. A conventional bucky IQ, of well known construction, is provided with grooved rollers 28 at each of its upper corners for engagement with the tracks l8, through the medium of which, the bucky is easily shifted from end to end of the top 9. The bucky l9 remains parallel with the upper surface of the top 9 at all times. The open side ll permits access to the bucky for insertion of sensitized plates and to permit clearance to control elements of the bucky. The bucky is connected by an electrical conductor 2|, leading to a plug-in socket 22, fixed to the under side of the table 5, as shown, with the conductor freely passing through

aligned slots

23 and 24, formed in the lower wall of the top 9 and the cover of the table 5, such an arrangement permitting the shifting movement of the bucky in any position of the top 9 without interrupting the flow of current. The plug-in socket 22 is detachably engaged by an electrical conductor from the conventional X-ray machine, not shown.

Since the bucky is freely shiftable upon the trackways l8, it follows, that means must be provided to counterbalance the weight thereof when the top 9 is swung to the vertical position, as in 1 Figure 2. To accomplish this counterbalancing, a pair of identical balance devices, indicated as a whole by the numeral 25, are arranged within the compartment l6 adjacent each side wall and parallel thereto and with each other. Each balance device includes a channel member 26, fixed upon the lower wall of the compartment I6 and extending for the full length of the compartment. Each channel 26 houses a balance within the bracket 28 and having an axial squared end 36 projecting therebeyond, as shown, through the medium of which adequate tension can be imparted to the spring 32 to compensate for the weight of the bucky. Any desirable ratchet 31 may be employed to maintain the spring in proper and predetermined tension. The free end of the tube is rotatably supported upon the head 35.

. 'Shiftably supported upon the tube 30, is a cylindrical ring 38, provided with an inwardly projecting key 39, that engages within the spiral slot 3|. The rings 38 are welded or otherwise fixed upon a bracket 40, in turn fixed upon the bottom of the bucky at opposite sides. It will therefore be apparent, when the bucky is manually shifted upon the trackways I8, the rings 38 partake of longitudinal sliding movement over the tube 30 and, since the rings cannot rotate, the keys 39 will traverse the spiral slots 3| in a straight line, causing the tubes 30 to rotate and increasing the tension upon the springs 32. Thus, the weight of the bucky can be balanced to a fine degree. While the balance devices will maintain the bucky against shifting, it may be found advantageous in some cases to provide a locking device between the bucky and the trackways. However,

this is a mechanical expedient and illustration thereof is not deemed critical.

In the use of the table, for examination purposes, the foot piece I3 is lowered to the dotted line position, after which a patient is placed upon the top 9, with or without a pad. If a vaginal examination is to be made, the conventional stirrups are engaged in the brackets l5, for the reception of the patients feet. The physician then proceeds with his examination, using the fiat end of the foot piece [3 as a rest for his instruments. If the table is to be used for horizontal fiuoroscopy, the foot piece I3 is elevated and latched in fixed position by the brace rod I4 r and, with the patient in the prone position, the

bucky i shifted along its trackways to the desired point beneath the patient. Horizontal radiography is conducted in the same manner. After the bucky has been properly positioned, a sensitized plate is inserted therein and the conductor from the X-ray machine is plugged into the socket 22. The

slots

23 and 24 permit freedom of movement for the conductor 2 I.

When the table is to be employed for vertical fluoroscopy, the foot piece I3 is first lowered by releasing the brace bar Hi. The table top 9 is then bodily swung upward to a perpendicular position, as illustrated in Figure 2 and is then looked in such position by the bracket l0 and clamp II. A patient is then placed in standing position against the vertical surface of the top 9 and the bucky shifted along its trackways l8 to the proper position, being counterbalanced and will remain in such adjusted position. The physician then proceeds with his fluoroscopic examination in the conventional manner.

It will be apparent from the foregoing, that a I very novel and highly advantageous combination table has been provided. The novel arrangement of the bucky, whereby it maintains its same relative parallel position with respect to the top 9 regardless of the position of the top, is highly advantageous, since the bucky is always in accurate spaced relation to the body of a patient and requires no separate mounting and swingin supports to bring the bucky into position when the table is swung to perpendicular pos-tion. Buckys heretofore employed are usually mounted with the table and are notshiftable with the table top and obviously require a separate and costly mounting in order to control the shiftin of the bucky when it is to be used in vertical fiuoroscopy. The device of the present invention combines a vertically swinging table top with its housed bucky always ready for-use. The novel balance means for the bucky is simple and highly effective and is easily adjusted as to tension. The table structure is simple, requires a minimum of floor space so important in the average physicians ofiice, is strong, ornamental and highly effective for the purposes designed. Further, the structure presented is relatively cheap, as compared with corresponding devices now in use.

It is to be understood, thatwhile a preferred example of the invention has been shown and described, various changes in the shape, size and arrangement of parts may be resorted to as will be determined by spirit of the invention or the scope of the subjoined claims.
