HENRY G- LEISENRING, OF WAYNE, NEBRASKA,

TILTING TABLE OR CHAIR,

SPECIFICATION forming part of Letters Patent No. 656,256, dated August 21, 1900.

Application filed January 29,1900. Serial Ho. 3,192. OTo model.)

To all whom it may concern:

Be it known that I, Henry G. Leisenring, a citizen of the United States, residing at Wayne, in the county of Wayne and State of 5 Nebraska, have invented certain new and useful Improvements in Tilting Tables or Chairs; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in io the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in surgical tables or chairs, and especially to the provision of means whereby the table may be tilted in any direction without moving the standard and 20 held in any fixed position desired.

The invention relates, further, to the nrovision of a surgical table or chair having a top which has a universal jointed connection with the supporting-posts, and the provision 25 of segment-braces which are connected at their ends to the under side of the table and are provided with notches, the said braces passing through apertures in the standard and adapted to be engaged by operating-le30 vers which are adapted to rest in the notches and hold the top of the table at any angle.

To these ends and to such others as the invention may pertain the same consists, further, in the novel construction, combination, 35 and adaptation of parts, as will be hereinafter more fully described, and then specifically defined in the appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with the let40 ters of reference marked thereon, form a part of this specification, and in which drawings similar letters of reference indicate like parts throughout the several views, in which—

Figure 1 is a vertical central sectional view 45 through the table and standard. Fig. 2 is a view at right angles to the section of Fig. 1. Fig. 3 is a detail view of an operating-handle. Fig. 4 is an enlarged detail view of the universal joint.

Reference now being had to the details of the drawings by letter, A designates the stand ard, mounted on suitable legs, and at its upper end is supported the top E, which has secured to its under side the plate B, with integral arms B', through which arms pivotal 55 screws &amp; are carried, which engage with the ball B² by being inserted in recesses on diametrically-opposite sides of the said ball. At right angles to the said apertures in the ball is the aperture B³, through which a bolt X 60 may be passed to support the said plate on the arms A' of the standard.

Pivoted or otherwise secured in the lugs F on the under side of the top of the table are the arcs or braces G and H, secured at right 65 angles to each other and passing through apertures g and h of the standard A. These arcs or braces are provided with notches G' and H' for the reception of the operating-levers C and D, which are pivoted to lugs on 70 the side of the standard and are provided, respectively, with lug C' and recess D', which are adapted to engage in the various notches of the arcs to hold the table-top tilted at the angle desired. 75

From the foregoing it will be seen that by the peculiar construction shown in the drawings-forming a part of this application my table may be tilted in any direction and firmly braced and steadied by the arcs which pass 80 through the standard and are held in a fixed position by means of operating-levers described.

In operation the levers are simply raised to allow the table to tilt and will fall by gravity, 85 with the lugs thereon engaging in a notch.
