' ike characters of reference indicate like and 18. The table is divided into two compartments by the transversepartition '19 to have drawers 20 and 21 in the head end comby two foot'end 2 posts '15 and 16, andthe head end posts 1-7 partment whereas the foot end compartment is left vacant and has a door 22 on the side to permit entrance therein. p

The topof the table is divided 'intoltwo sections, a main top cover 23 extending from the/head end to just over the edge of the Between the two foot end posts l5, and .1 6

the tops of the' posts, and has" an appreciable width; Abasin 26-rests on this top edge of thezpanel 25 by its forward edge. The'basin 26 is of peculiar conformation and'has'a top 7 v flange extending outwardly from; itsytwo side wallsand the back wall from the top ment above described from its top' side. There is no flange-from the ,front'or foot end ofthe basin, but the end wall of the basin I partition 19, and a basin cover 24 which will I l be described more in detail'laterp i i edges to fully enclose the foot end compart the main-floor 29 of -the"ba'sin, in which is] a hole 30 to permit drainage intoa pail 31 in the table compartment below, or the' hole30 may be connected suitablyitoasewer connec-" tion. A stopper. (not shown) may be used inthedrain'l1ole'3O if desired.

The basin 26 is supported at the rear by the'two restsr32spaced apart and; bearing 7 against the under side of the rear flange 33, Figs. 9 and 10. Each of the rests 32 has a depending section entering a bracket 34 to slide vertically therein. The lower end of each of these depending sections is correspondingly bevelled or cut at an acute angle, and wedge shaped cams 35 mounted on a transverse bar 36 slidably passing through each of the brackets 34 contact these bevelled ends from below.

Between the brackets 34, a lug 37 is secured to the bar 36 to extend outwardly and upwardly and a shaft 38 is screw-threadedly passed through the lug 37. The shaft 38 extends out through the table side wall 39 to there terminate and be held against endwise displacement, and be engaged by a detachable crank 40.

By suitably rotating the shaft 38, the lug 37 is caused to travel along the threaded end of the shaft 38, thereby carrying the cams 35 under the depended ends of the rests 32 which action forces the rests 32 upwardly to in turn lift the rear of the basin 26. Reversing the direction of rotation of the shaft 38 will permit the basin to be lowered.

In place of the elevating means as above described in reference to Fig. 9 of the drawing, the modified form as shown in Figs. 13 and 17 inclusive may be employed to considerable advantage in that in the modified form but one bracket has to be mounted on the table partition wall 19 in place of the two brackets 34 which must be carefully aligned one with the other to permit the bar 36 to slidably pass therethrough.

The modified elevating means comprises the single bracket housing mounted on the wall 19 by the ears 71 and 72, the vertical slide 73 and the transverse actuating slidebar 74. The slide 73 is loosely carried within the housing 7 0 and has on its forward face, the two vertically positioned, parallel guides and-7 6 which slidably fit within the central groove formed in the housing wall.

The slide 73 carried the two rests 77 extending from its top edge on which the basin flange 33 rests. On the rear face of the slide 73 is an integral diagonally positioned lug 78. The transverse slide-bar 74 carries by its inner end a head 79 having a face cut on the same angle as that of the lug 78, and the bar 74 rests on the lower edge 81 of the housing 70 and projects therefrom with a head 82 on the outer end. The slide 73 and bar 74 are retained in the housing 70 when it is secured to the partition wall 19, whichgin fact forms the rear wall of the housing 70. 7

The head 82 hasa hole 83 therethrough to screw-threadedly receive the shaft 38. The housing 70 is mounted centrally of the wall 19, and by suitable rotation of the shaft 38, the head-'82 will corresponding travel along the shaft 38 to in tur'n'cause the head 79 by its face 80 to travel against the lug 78 whereby the slide 73 will travel upwardly, since the guides 75 and 7 6 prevent lateral travel. Reversing the rotation of the shaft 38, of course, permits the slide 73 to drop back down.

As a means of maintaining the basin 26 in position as it is tilted to raise the back end with the forward or foot and resting on the top edge of the panel 25, a. flange 66 is extended laterally from each side of the basin 26 to enter into grooves or slots 67. These slots 67 are just wide enough at the top to permit the flanges 66 to enter therein as the basin 26 is let down to rest along its lower front edge on the panel 25. The back sides of the slots 67 are inclined backwardly from the top opening so that the slots are wider at the bottom than at the top (Fig. 8).

When the basin 26 is raised at its back end, the front end bears by the flanges 66 against the forward faces of the slots 67 near their top ends and the lower edge of the basin thereby slides back on the top of the panel 25.

A board 41 is employed to fit between the upper ends of the posts 15 and 16 to cover the opening from the foot end into the basin and also to carry the leg extension or support 42. The board 41 fits by one end into a bracket 43 secured to the post 15, Figs. 2 and 5, and is swung around across and against the basin 26 to have its other end rest on the lug 44 of the bracket 45 secured to the post 16. The bracket 45 has an outwardly extended section 46 with a slot 47 therethrough, through which is passed a latch bar 48 carried by'the arm 49 pivoted to the post 16, whereby thebar 48 passes in front of the board 41 and thereby securely retains the board in position.

' The leg extension 42 is hinged to the board 41 near its top edge by the hinges 50, and carries a foot rest 51 hinged to its lower edge. As ameans to control the relative angle of the rest 51 with the extension 42, a bar. 52 is hinged to the board 41 at each side near its lower edge and extends downwardly to engage pivotally with the rear extensions of the foot-board levers 53. By pivoting the bars 52 at the lower edge of the board 41 and having the leg rest 42 hinged at the top of the board, the foot-board 51 is caused to swing downwardly to approach the plane of the leg rest 42 as the. leg rest 42 is elevated, as in swinging the rest 42 from the dotted line position to the full line position as shown in Fig. 1.

Two backwardly curving brace bars 54 are pivotally attached to thelower edge of the board 41, one on each of the same pivots as carries the bars 52, and extend along the under or back side of the extension 42 through yokebrackets 55. The edges of the bars 54 toward the extension 42 are provided with a series of notches 56 into which may engage the dogs 57 carried by a transverse shaft 58 mounted on the yoke brackets 55 and operated from one side of the extension 42 by'the han-,

bars 54 so that by raising the extension to the desired elevation, the dogs 57 may drop into the notches 56 of the bars 54 presentedthereunder at that elevation which engage ment effectually retains the extension at that elevation until the dogs 57 are rocked back from the notches by the handle 59.

A splash apron 60 is secured to the back face of the board 41, Figs. 3, 4, and 10 in such manner that the apron may project back over the upturned basin lip 27.

Referring again to the basin cover 24, this cover is removably positioned over the basin 26. The two fingers 61, Fig. 11, extend from the'under face of the cover to project under theedge of the main top cover 23 and a transverse cleat 62 is positioned on the under side of the cover 24 to contact the board 41. With such means provided, the cover 24 can not accidentally be slid off from over the basin but must be actually raised at its foot end and then pulled back before it maybe lifted f ried by the table covering sald cut-away s de,

off entirely. The main top cover 23 is hinged whereby the head end may be elevated to a position such as is indicated by dotted lines in Fig. 1,

and a head rest 63 is hinged to the table to permit being swung up into position as also is indicated in Fig. 1.

In using the table, the top '23. may be brought to the dotted line position and the extension 42 dropped to its dotted line position, both as indicated in Fig. 1. The patient may then sit on the table from the foot end which is then presented as a chair, or the top cover 23 may be left in its horizontal position and the patient caused to lie down on the table top with the basin cover 24 in position and the leg extension raised, all as shown in Fig.1, Where the patient is indicated by dotted outline.

The patients feet are then positioned in the adjustable stirrups 64, or more preferably the crutches 65 are placed up and under the knees as supports. The patients legs then being elevated and removed from the extension 42, it may be lowered and the supporting board 41 removed, whereupon the examination of the patientmay be made.

When irrigation is desired, the basin cover 24 is lifted by its foot end and slipped out from under the patient, and the'crank 40 is turned to bring the rear flange 33 of the basin 26 up tight against the patients hips, asin Fig. 12, so that the irrigating liquid will flow into the basin and not soil the patients clothing. As the front of the basin 26 is cut away, the attendant may" erform the irrigating operation easily an keeping. thefiuid v 'tendant. normally position the dogs 57 against the readily with out hindrance or obstructed view, and therest forinstruments but: also as a. meansof;
