Specification of Letters Patent.

Patented J an. 18, 1916.

Application filed August 30, 1915. Serial No. 48,023.

To aZZ 'who'nrit may concern:

Be it known that I, S'JEP'IIEN JENIGAR, a citizen of the United States of America, residing at' Cambridge, in the county of Guernsey and State of Ohio, have invented certain new and useful Improvements in Ships Tables, of which the following is a specification.

This invention relates to new improvements in ships tables.

The primary object of this invention is to provide a tiltable table especially designed for use upon ship board, the table being so constructed as to normally maintain the supporting top thereof horizontally, the table top being also restrained against rotation.

A further object of the device is the provision of a table provided with a means for automatically returning the supporting-top thereof to a horizontal position upon any tilting thereof or the support therefor, the relative movements of the top and support being in restrained paths of travel whereby relative rotation of the top and support is prevented.

A still further object isto provide an antifriction mounting means for a table top, the said top being adapted to maintain its normal horizontal position.

\Vith these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and then claimed.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views :Figure 1 is a side elevation of the device partially broken away. Fig. 2 is a horizontal sectional view through the shiftable mounting means for the table top, the supporting frame being partially broken away. Fig. 3 is an enlarged detail central sectional view through the device, parts thereof being removed, and Fig. 1 is an interior elevational View of aportion of the support carried anti-friction members.

Referring more in detail to the drawings,

and useful the invention broadly consists of a table top 10 here illustrated in the form of a circular disk, the same being so mounted upon oppositely arranged supporting legs 11 as to be normally positioned horizontally when i the table is tilted as occasioned by the movement of a ship when the table is positioned thereon.

The legs 11 of the table are vertically ar-' ranged connected to the outer ends of the arms 12 of a spider frame which has a central circular collar 13 from which the said arms 12 radiate, it being understood that the 11 are positioned upon any support desired, such as the deck 14 of a ship.

The collar 18 has its inner face 14 curvilinear in cross section and whereby the lower inner edge 15 thereof is of less diameter than its upper edge 16. A plurality of spaced angular sockets 17 is arranged in the collar face 11 adapted for the reception of anti'friction balls 18 while a cover or cage plate 19 is countersunk in the face 14: for overlying the said sockets 17 and is provided with perforations 20 of less diameter than the said balls 18 and adapted to freely fit thereover, thus maintaining the balls adapted for rotation within the sockets 17.

A supporting sphere or bearing ball 21 is centrally secured by means of a plate 22 to the under side of the top 10. Substantially parallel grooves 23. are arranged upon the periphery of the ball 21, the space thereof being adapted to accommodate the balls 18 within the grooves 23 when the supporting sphere 21 is positioned within the said collar 18.

A depending rod 2 1 projects from the sphere 21 after the manner of a pole and is perpendicularly arranged with respect to the table top 10 and has a screw-threaded portion 25 at its free end adapted for the adjustable reception of a Weight 26 after the manner of a pendulum.

From this detailed description of the device it will be seen that when the supporting legs 11 are mounted upon a ship, any tilting of the said legs and the supporting spider 12 allows the same to move relatively of'the eration of the memb 4 the said balls,

the grooves 23. It will be understood that the widening of the grooves 23 compensates for the convergence of the grooves 23 and allows a slight play of the balls 18 within the said grooves, thus'preventing any fricv.tional binding between the sphere 21 and collar 13 although allowing the perfect opers.

While the form of the invention herein shown and described is What is believed to be the preferred embodiment thereof, it is nevertheless to be understood that minor changes may be made in the form, proportion and details of construction without departing. from the spirit and scope of the invention as claimed.

What I claim as new is 1. A. ships table comprising a support having a centrally arranged mounting collar circular in cross section and provided with spaced angular sockets in the inner side thereof, anti-friction balls within the said sockets, a cover plate for-the said sockets provided with receiving openings for a table top, and a mounting member carried by me said top guidingly ,shiftably mounted upon the said balls.

2. A ships table comprising asupport having a centrally arranged mounting collar circular in cross section and provided with spaced angular sockets in the inner side thereof, anti-friction balls within the said sockets, a cover plate for the said sockets provided with receiving openings for the said balls, a table top, a spherical mount centrally secured to the under side of the said top and having substantially parallel grooves arranged in the periphery thereof and terminating adjacent "the said "top, the said mount being positioned within the said 0 collar with-thessaid balls-seated within the said grooves, a pendulum rod projecting from the said mount beneath the said collar perpendicularly to the said top and a return weight adjustably arranged upon the said rod.

3. A ships table comprising a mounting collar having a grooved inner face, the lower edge of which is of less diameter than the upper edge thereof, a table top, a spherical mount carried by the said top and shift-,4 ably positioned within the said collar, and, rotation preventing means for the said top provided upon the said collar and mount.

4. A ships table comprising a mounting collar having a'grooved inner face, the lower edge of which is of less diameter than the upper edge thereof, a table top, a spherical mount carried by the saidtop and shiftably positioned within the said collar, anti-friction members for the said mount carried by the said collar, the said mount being provided with relative. rotation preventing guide grooves receivingly engaging the said anti-friction members and a pendulum rod and weight attached to the said mount beneath the plane of the said collar.

Intestimonyavhereof I affix my signature.
