The plate I is provided with aligned longitudinal slots 2 adjacent one edge 3. v

The rod-like posts or uprights 4 are provided with bases 5 having sockets 6 therein in which thesupport shown in a horizontal osition;

Theslots 2 are-dove tailed or under cut. at 8*;to receive. the noncircular heads- 9; of the-,post.- clamping; bolts iatwhich; areprovided with clamping: nuts H; having:- knurled portions to facilitate. adjustment. It will be; noted, that; these clamping nuts. i 1 are accessibleirom the topof the base-plate; so: that the posts. may. be; independently adjusted longi todinally ofi thebase-plateand relative to each other with. the, base. in. upright position.

Each post is provided with a. crossbar supporting, bracket I 2', the brackets illustrated being tubular in form. and slfeevejdf upon the posts. for

vertical adjustment. These brackets illustrated have laterally projecting bosses I3 into which the sets'crews' l 4 are threaded'tc clampingly engage the p'osts.

permitsthe crossbar beingswing'ingly adjusted on theother post. the brackets. I'Zbeing rotat'- able on the post and secured in adjusted posi-. tions by the setscrew Hi. This is desirable for-- in some conditions the post might obstruct the surgeon.

The apparatus can be placed in various posi-.

tions on a surgical table to meet the particular conditions, the adjustable anesthetic screen or support can be adjusted for particular conditions and at the same time enable the anesthetist to observe the patient without interfering with the surgeon or the operative field. The device is sufliciently strong and rigid to permit use by the anesthetist or surgeon as an arm rest. The apparatus is particularly desirable for use in eye, mastoid and thyroid surgery but may be used to advantage for other types of surgery.

I have illustrated a highly practical embodiment of my invention. I have not attempted to illustrate other embodiments or adaptations as it is believed that this disclosure will enable those skilled in the art to embody or adapt my invention as may be desired and also to use it in an effective and eificient manner under varying conditions for which it is adapted for use.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In an apparatus of the class described, the combination of a plate-like base of substantial area and weight having undercut longitudinal slots positioned adjacent one longitudinal edge thereof and extending inwardly from adjacent the ends thereof, posts provided with bases slidably supported on said base, said bases havin ribs on their undersides sli-dably engaging said slots, clamping bolts disposed through said post bases and having noncircular heads disposed within the undercuts of the slots whereby rotation thereof is prevented, said bolts being provided with clamping nuts at their upper ends accessible from above the base and alongside the post whereby the post may be independently adjusted longitudinally of the slots and are removably attached to the base, crossbar brackets sleeved upon said posts for vertical adjustment thereon and provided with transverse openings and with setscrews for securing them in their adjusted positions, a crossbar comprising inner and outer telescoping'section disposed with their outer ends in said openings in said brackets, said brackets being provided with setscrews for securing the rod sections thereto, and a semicircular foraminated support provided with ears located adjacent its straight edge and rotatable and slidable upon said outer crossbar section, said ears being provided with setscrews for securing the support in its adjusted position longitudinally of the crossbar and in its tiltably adjusted position thereon.

2. In an apparatus of the class described, the combination of a plate-like base of substantial area and weight, upstanding posts laterally adj-ustably supported on said base, crossbar brackets sleeved upon said posts for vertical adjustment thereon and provided with transverse openings and with setscrews for securing them in their adjusted positions, a crossbar comprising inner and outer telescoping sections disposed with their outer ends in said openings in said brackets, said brackets being provided with setscrews for securing the rod sections thereto, and a semicircular foraminated support provided with ears located adjacent its straight edge and rotatable and slidable upon said outer crossbar .section, said ears being provided with setscrews 4 for securing the support in its adjusted position longitudinally of the crossbar and in its tiltably adjusted position thereon.

3. In an apparatus of the class described, the combination of a base of substantial area and weight having undercut longitudinal slots positioned adjacent one longitudinal edge thereof and extending inwardly from adjacent the ends thereof, upstanding posts provided with bases slidably supported on said base, said bases having ribs on their undersides slidably engaging said slots, clamping bolts disposed through said post bases and having noncircular heads disposed within the undercuts of the slots whereby rotation thereof is prevented, said bolts being provided with clamping nuts at their upper ends accessible from above-the base and alongside the post whereby the posts may be independently adjusted longitudinally of the slots and are removably attached to the base, crossbar brackets sleeved upon said posts for vertical adjustment thereon and provided with transverse openings and with setscrews for securing them in their adjusted positions, a crossbar in said openings in said brackets, said brackets being provided with setscrews for securing the rod sections thereto, and a support slidably and tiltably mounted on said crossbar.

4. In an apparatus of the class described, the

combination of a plate-like base of substantial area and weight having slots formed therein extending inwardly from opposite sides thereof, upstanding'posts supported on said base and having clamping bolts secured to their lower ends and projecting through said slots with the heads of the bolts underlapping the base at the sides of the slots, said bolts extending upwardly through said slots and having clamping means at their upper ends accessible from above the base and coacting between said bolts and said posts to clamp said posts and said heads on the top and bottom of said base whereby the posts are releasably clamped to said base and are independently adjustable thereon, a telescopically adjustable cross bar mounted on said posts for vertical adjustment thereon, and a foraminateplate rotatably and slidably mounted on the cross bar and provided with means for securing it in its adjusted positions thereon, said foraminate plate being narrower along the portion thereof connecting to said cross bar than the length of said cross bar.
