This invention relates-to a surgical operating table and it is an object of this invention to provide such a table upon which house animals can be readily strapped and which is adjustable for operating at any desired angle.

.The invention comprises the novel struc- 'ture and combination of parts hereinafter described and more particularly pointed out and defined in the appendedclaims.

In the accompanying drawings, which illustrate aopreferred embodiment of this invention. and in which similar reference'nu- .merals refer to similar featuresin the diiferent views:

Figure '1 is an elevational view of a surgical operating table involving this invention.

Figure 2 is a bottom plan view of the table detached from its pedestal.

Figure 3 is an enlarged central longitudinal section.

Figure 4 is an enlarged transverse sectional view taken upon the line IVI V of Figure 1.

Figure 5 is an enlarged sectional view taken upon the line VV of Figure 1. Figure 6 is an enlarged sectional view taken upon the line VIVI of Figure 1.

Figure 7 is an enlarged part elevational and part sectional view of the pedestal.

Figure 8 is an enlarged sectional view taken 33 upon the line VIIIVIII of Figure 7 A form of table illustrating this invention is shown in the drawings. The same consists of a dished top or operating part 1 to which a vertical shaft 2 is attached that telescopes in a tubular standard 3. Any means for relatively adjusting the two parts 2 and 3 to secure the desired elevation for the table top may be employed, but hydraulic power, as now used in barber chairs, is preferred.

The table top comprises longitudinal side beams 4 and end beams 5 secured together and upon which a dished sheet metal member 6 is supported. The sheet metal member 6 has depending flanges 6a which extend downwardly over the beams. Suitable transverse braces 7 extend between the longitudinal beams 4;. Between the braces 7, there is a plank or slab 8 of wood. Upon this plank there are a pair of castings 9 which are provided with hinged lugs 9a as shown in Figure 1928. Seria1No...L279,649.

Vided with a cylindrical bearing or stub shaft 13 fitting in said recess is supportedbysaid .arm. Thestu-b shaftv is-shownas provided with agroove 13 for receiving a screwl tto retain theswivel block with freedom for rotation. A rod 15 secured to a casting 16 .upon the bottom of the plank..8 extends through an aperture in the arms ofthe-swivel block 12, which are-formed by the bifurcation thereof. vBetween these arms .are friction brake members 17 having theininner ends anchored in slots18 in the swivel block-and having apertures for receiving the rodI15. A .coil spring 19.,surr0undsthe rod 1'5.betwe.en the two. frictionbrake elements 17 v for ,forcing the same apart and causing them toeXercise a frictional or. braking action, upon the rod 15. The central armlQa betweenjthe friction brake members limits thejmovement :of the same toward eachother whenthesame are free from frictional engagement with rod 15 to; prevent .anyibl'akingjaction whenrthe membersare drawn together. When it isdesired-to tilt the table .top the brakeelements 17 are moved toward. each other to relieve their braking action upon therod 15 whereupon; the rod 15 can slide.throughthe swivel -block to allow the table tobe tilted, the swivel block rotating in accordance with thetilting movement.

In operating uponanimals, itlis necessary to strap .-or tie the same upon thetable, .and .for this purpose longitudinally adjustable cord anchors 18. are provided :uponlthe \bottom of the table. .To. :thisend; rodsl9, one beneath each -longitudinal beamA, are provided. These rods are supported by means of suitable angle clips 20 upon the beams 4c and 5. Each cord anchor 18 consists of a casting (Fig. 6) having an inwardly directed apertured arm 21 for receiving the rod 19. Each casting has a depending shank and head 22 (Fig. 1) around which shank a cord or the like is adapted to be wound, and side extensions 23 (Fig. 6) which are enlarged to form a depression therebetween for receiving the cord. These extensions 23 are provided with mortises 24: or the like for receiving the inner ends of brake elements 25 which have bearing apertures through which the rods 19 eXtend. Between each brake element 25 and the bearing 21, there is a coil spring 26 which acts against its adjacent brake element for forcing the same in an oblique relation with the rod 19 for exercising a frictional or braking action to maintain the cord anchor in its adjusted position. The bearing arms 21 are preferably provided with laterally directed shields 27 for confining and housing the springs 26 and for limiting the inward movement of the elements When it is desired to shift the cord anchors 18, the brake elements 25 are moved toward each other to relieve their braking action upon the rods 19, allowing the said cord anchors to be shifted longitudinally.

Each cord anchor 18 has an upwardly extending grooved portion 28 (Fig. 4L) the groove of which slidably fits a horizontal flange on an angle member 29 secured to the inner side of the beams whereby the cord anchors are anchored against turning move ment upon the rods 19 and part of the strain removed from the rods 19. In the drawings, a pair of cord anchors 18 are located upon each side of the table, but it is obvious that any desired number may be used.

It has previously been mentioned that the pedestal shaft 2 and table may be elevated or lowered. To this end a shaft 30 (Figures 7 and 8) extend through the pedestal shaft 2 which is shown as hollow. The shaft 30 is provided with an operating handle 81 and a pitman 32 connects the shaft 30 with the pump or hydraulic means in the pedestal 5,

as is common in the art.

From the foregoing, it will be apparent that a novel operating table has been devised upon which domestic animals such as cats and dogs or other animals may be securely strapped and operated upon. By adjusting the anchors 18, the cords can be easily adjusted to fit difierent sized animals. Moreover the operating table can be tilted, if necessary or desirable, to perform certain operations or examinations. Further, the braking elements 17 or 25 can be quickly reached and quickly operated to effect the desired adjustment without any delay or loss of time during the surgical operation.

I am aware that many changes may be made, and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

I claim as my invention:

1. A surgical operating table having side rails, cord attaching members upon said rails, each comprising a hollow bearing portion to receive a rail, and having a chamber adjacent each end of said bearing portion with a notch adjacent the outer end of each chamber, a coil spring within each chamber, and a friction lever mounted upon said rail adjacent the outer end of each chamber and having one end located in the adjacent notch, said levers having their free ends extending downwardly.

2. In a device of the character described, a pedestal, a plate member thereon, atable top hinged to said plate member for tilting movement, an arm extending from said pedestal in a direction opposite from said hinge connection, said arm having a socket upon one side, a clamping block having a ournal portion rotatably mounted in said socket, a rod pivoted to the bottom of the table and adjustably extending thru said clamping block and frictional clamping levers carried by said block for clamping said rod in adjusted position, said clamping block rotatably adjusting itself for various inclinations of said roc. V

In testimony whereof I have hereunto subscribed my name.
