swrnonio TABLE.

Application filed September 16, 1925. Serial No. 56,809.

This invention relates to improvements in swinging tables particularly adapted though not necessarily limited in its use with and adapted to be connected to a chair, and one of the objects of the invention is to: provide about a fixed pivot and being provided with a ball or roller bearing to facilitate the move;

ment of the table.

A further object is to provide an im proved table of this character that may be readily mounted or secured in position and which will be of a simple and compact arrangement and so constructed that when the table .isapplied to a chair a plurality of chairs may be arranged close together and the operation of the table on one of the chairs will not swings over the next adjacent chair. 7

To the attainment of these ends and the accomplishment of other new and useful objects as will appear the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts, hereinafter more fully described and claimed and as shown in the accompanying drawing and in which, I

Figure 1, is a top plan View of a chair having a table constructed in accordance with the principles of this invention applied thereto, showing in full lines the table in one position and in dotted linesthe table in another position.

Figure 2, is a vertical sectional view taken on line 2 2 Figure 1.

Figure 3 is a sectional view on line 3-3, Figure 2.

In the drawing the numeral 10 designates a chair, one of the front supporting legs 11 of which extends above the seat 12.

A bracket 13 preferably formed of a casting is provided with a downwardly opening socket 141; into which the upper extremity of the leg 12 projects and the bracket may be secured in position in any suitable manner such as by means of a flange or projection 15 adapted to rest upon the seat 12, and a fastening device 16 such as a screw passes through the flange and into the seat. I

This flange 15 also serves as a supporting means for. the bracket and assists in supporting the seat.

The bracket is provided witha projecting portion or arm 17 which preferably extends for a. short distance over the seat 12 and is provided with spaced stops 18- 19 I ,A table 20 of any desired size and configuration and preferably provided with an upstanding peripheral liange21 is mounted upon the bracket 13,'preferably on the arm 17, by means of a pivot member 22 which preferably passes through the arm 17 from the bottom thereof and has engagement with the table 20.

A roller bearing preferably in the form of balls 23 is interposed between the table and the upper surface of the arm or projection 17 to facilitate the movement of the table about the pivot, the balls being disposed in opposed grooves in the arm and table.

The pivot 22 is preferably in the form-of a screw or bolt and also serves as a means for holding the balls .23 against displacement.

Depending from the table is a lug or projection 24 which moves between the stops 18 and 19 and is adapted to engage the stops to limit the extent of pivotal movements of the table in the respective directions.

If desired the projection may be covered with any suitable material, such as rubber or the like (not indicated) to reduce the noise which would be occasioned by the lug striking either of the stops 1819.

The pivot point of the table is preferably located adjacent one end of the table, as shown, so that the table when in use will project over the seat 12 and when not in use by an occupant of the chair, the table will extend along the side of the chair and the stop 19 and lug 24 will prevent the table from projecting over the next adjacent chair or interfering with the occupant of the next chair.

This is accomplished by reason of the fact that the table will at all times be maintained substantially within the plane of the adjacent side of the chair.

This arrangement also renders it possible to arrange chairs having tables of this character connected therewith in close proximity to each other without danger of one of the tables swinging over the next adjacent chair as the table will at all times be maintained in close proximity to its support.

As a means for maintaining the table 20 in its adjusted position thereinay be provided on the faces of the stops 17 and 19, which are adjacent the bottom of the table, inclined or cam shaped portions 26, and cam shaped portions or inclined faces 27-28 may be provided on the lower surface of the table 20. These faces 27-28 respectively co-op-erate with, the inclined or cam shaped portions 26 on the stops 18 and 19 at the time when the table about reaches the limit of its respective movements. The respective cam faces or inclined portions will then ongage each other and a further movement of the table in the respective directions will cause a wedging or binding action to be created betweenthe bracket and the table and thereby yieldingly retain the table in its adjusted position.

The binding action, however, is not sui'licient to prevent a ready movement of the table about its pivot when desired.

While the preferred form of the invention has been herein shown and described it is to be understood that various changes may be made in the details of construction and in the combination and arrangement of the several parts, within the scope of the claims, without departing from the spirit of this invention.

What is claimed as new is:

1. In combination, a support, a bracket secured thereto, a table mounted upon the rate from said pivot for causing a binding actlon between the table and support for yieldingly retaining the table in its adjusted position, the second recited means embodying friction surfaces movable into and out of contact as the table is swung about its pivot. 1

3. In combination, a support, a table con-' nected with the support to swingabout an upright pivot, means forlimiting the swinging movement of the table, and means separate from the pivot for causing abinding action between the table and support for yieldingly retaining the table in its adjusted position, the last recited means embodyed respectively by the table and the support, said surfaces being movable into and out of frictional engagement as the table is moved about its pivo In testimony whereof we have signed our names to this specification on this 12th day of September, A. D. 1925.
