ADJ-U STAB LE TABLE.

SPECIFICATION forming part of Letters Patent N 0. 659,532, dated O tober 9, 1900. Application filed February 23, 1900. Serial No. 6,217. (No model.)

To all whom it may concern:

Be it known that I, HENRY S. JORDAN, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented new and useful Improvements in Adjustable Tables, of which the following is a specification.

This invention relates to certain new and useful improvements in adjustable tables, and has for its object to support the table upon a ball or sphere, so that the former can be tilted in order to adapt the same for use for various purposes; and it consists of the novel combination and arrangement of parts hereinafter more specifically described, illustrated in the accompanying drawings, and particularly pointed out in the claim hereunto appended.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, wherein like letters of reference indicate corresponding parts throughout both views, and in which Figure 1 shows a side elevation of an adjustable table constructed in accordance with my invention. Fig. 2 shows a vertical sectional View through the center of the table and the table-support.

Similar letters refer to similar parts throughout both views.

A represents a table, which may be of any suitable form and which is secured rigidly to the segment F, and F is a segment'adapted to inclose the upper part of the ball 0. This segment is provided with a flange, as shown.-

G represents an annular body or ring which surrounds the ball 0 and extends below the line drawn horizontally through the center of the ball. The ring Gis also provided with a flange B. WVhen the ring G and the segment F are in position, there is a space between the ring and the segment. In order to secure the segment and ring in position to engage the ball 0, I provide a series of screwbolts, (shown by D.) I prefer to use four of such bolts; but a greater or less number may be used.

In the drawings the table A is shown in a horizontal position, but may be tilted or turned to any required position. Then by tightening the securing-bolts D the flange of the segment F and the flange of the ring G are drawn toward each other, and the ball 0 is clamped between the segment and the ring and is thereby adjusted and held rigidly to the required position. When the table A is in a horizontal position, I provide a pin or bolt E, which passes through the wall of the segment F and through or partially through the wall of the ball 0.

In the drawings I have shown the ball 0 hollow; but it is evident that the same may be made solid, if desired. The ball 0 is supported upon a standard S of any suitable form or shape, which standard may be secured to the floor or to any other body or support.

My adjustable table is peculiarly adapted for use in factories for holding stock to be 0perated upon by any suitable machinery or tool. It is also adapted for the support of tables of any kind where it is desirable to adjust said tables to different angles.

In the drawings 1 have shown the table made integral with the segment B. Ordinarily, however, the table would be made separate from the segment and attached thereto by means of bolts, screws, or other suitable means.

Having thus described my invention, what I claim to have invented, and desire to secure by Letters Patent, is

In an adjustable table, a standard, a ball formed integral therewith, a ring surrounding said ball below the horizontal center thereof, an outwardly-extending annular flange formed integral with said ring, a t-able,a hollow segment secured thereto and mounted upon the top of said ball, an outwardly-extending annular flange formed integral with the lower part of said segment and parallel with the flange upon the ring, a series of bolts extending through said flanges for causing the frictional engagement of the segment and ball for retaining the table in the desired position, and separate means for securing the table in a horizontal position, substantially as described. 7

In testimony whereof I have'hereunto set my hand in presence of two subscribing witnesses.

HENRY S. JORDAN. Witnesses:

EDWARD TAGGART, ELIZABETH J. PHILLIPS.
