- Application Mai-t1. 6,1950, Serial No. 147,807 1 3 ol iinsl (01. 243 -229) I This invention relates-to an arm support for use in conjunction with operating beds or tables,

being primarily concerned with a novel, practical and very useful support for the arm of a surgeon, or others engaged in an operation, for steadying the arm and supporting it.

It is an object and purpose of the present invention to provide anarm support which may be mounted for adjustment to any desired position in the length of the bed, is also adjustable for a swinging movement to different angular The. ears -Imand. Illafa're. mounted for angular positions, and further adjustable vertically for obtaining the right height for the rest or support of the arm.

An understanding of the invention may be had from the following description, taken in connection with the accompanying drawing, in which,

Fig. 1 is a perspective view showing the arm support of my invention attached to an operating bed, shown fragmentarily. 1

Fig. 2 is a side elevation of the arm support, the rail on the bed on which the support is mounted being shown in vertical cross section.

Fig. 3 is a horizontal section on the plane ofline 3-3 of Fig. 2.

Likereference characters refer to like parts in the difierent figures of the drawing.

In the structure of the arm support, an elongated plate I of thin metal, which in practice may be aluminum, has downturned flanges 2 at its longitudinal side edges, the juncture of said flanges and the sides of the plat I being raised slightly in longitudinal rims 3, one at each side of the plate I, upon which the arm is to rest. Said plate I, at each end, is extended as indicated at 4 and curved or bent downward slightly The post 5 extends through the loop 8 and is adjustable to different positions. It is clamped and held in any desired position by tightening the screw at 9.

A slidably mounted bracket ID has an intermediate vertical portion, and at its upper end an overhanging shoe II. Adjacent its lower end extending oppositely from the shoe II, is an ear Illa located underneath a complementary ear la at the end of the bracket! opposite the loop 8.

adjustment with respect to "each other and are held in a position wanted bytightening a clamping screw I2.

At the lower end of the intermediate vertical section of the slidemounting I0, a block I3 is located through which the lower end of a screw I4 passes for vertical movement of the block I3. The block I3 is a holding or clamping block which tightens against the under edge of a bar I5, located at a side of a surgical bed or table I6. Thus the structure is adjustably mounted on the horizontal bar I5 and is held in any selected position to which moved by tightening the screw I4. The bracket I may be swung to difierent angular positions and held by tightening the screw at I2, and the post 5 and connected parts are adjustable vertically within the limits of the length of the post and are held in a selected osition by tightening the screw at 9.

The overhanging shoe I I is stepped on its under side so that it will receive bars I5 of different widths. V

The construction described is practical and useful. The arm resting on the plate I is supported against accidental or other undesired movement and is of utility in connection'with surgical beds and tables.

The invention is defined in the appended claims and is to be considered comprehensive of all forms of structure coming within their scope.

I claim:

1. In a. structure of the class described, a bracket having a vertical portion and a shoe extending horizontally from the upper end portion thereof to one side, adapted to ride upon a horizontal bar support, means for releasably clamping said bracket to a horizontal bar support, said bracket having an ear integral therewith extending from its vertical portion opposite to said shoe, a member pivotally connected at one end to said ear to turn about a vertical axis, and extending away therefrom generally in the same direction as said car, a vertical post, and means for adjustably connecting said post to the opposite end portion of said member, and for releasably holding said post in any position to which adjusted.

2.'In a structure of the class described, a bracket having a vertical portion adapted to lie alongside of a vertical side of a horizontal bar support, and having an integral shoe at its upper end adapted to extend over and ride upon the upper edge of said bar support, releasable, manu-- ally operable clamping means for clamping said bracket at different adjusted positions thereof post at the outer end of said member for vertical.

adjustment combined-with means for releasably securing said post in a selected adjusted position.

3. In a structure of the class described, a clamp including a vertical section, anda laterally ex tending shoe at its upper portion adapted to ride on a horizontal carrying bar,-a clamping block located at the lower end of the said vertical sec tion, adapted to bear against'the under side of said bar, screw means for drawing said block into Number clamping position, said vertical section having a laterally extendingear, an arm having an car at one end overlapping said first mentioned ear,

means for pivotally connecting the two ears and for clamping them together to secure them in adjusted position relative to each other, said arm at its outer end having an integral loop providing a vertical passage, a post extending through the passage in said loop-, and means to clamp the loop against said post.
