SELF-LEVELING TABLE.

Application filed November 11, 1916. Serial No.

To all whom it may concern:

Be it known that we, ANDREW KURUNozI and MIonAnL BALINT, subjects of the King of Hungary, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Self-Leveling Tables, of which the following is a specification. This invention relates to certain new and useful improvements in self-leveling tables. An object of the invention is to provide a table for ships, preferably a dining table, that will always assume a horizontal position regardless of the roughness of the sea or a the rocking of the boat. This object is attained by suspending the table top with a pendulous weight beneath the same, the weight being of a size to hold the table top in a normally-horizontal position.

With the above and other objects in view which will appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts to be hereinafter more fully described and then claimed.

In the accompanying drawing which shows the preferred embodiment of our invention, and to which reference is had therein by like characters denoting corresponding parts through the several views:

Figure 1 is a side elevational view of the table, with a portion of the base broken away, better to illustrate the manner of mounting the table top.

Fig. 2 is a horizontal sectional view taken on line 11-11 of Fig. 1.

Fig. '3 is a vertical sectional view of a portion of the table and its mounting, and taken at right angles to the view shown in Fig. 1.

Fig. 4 is a vertical sectional view taken on the line TV-IV of Fig. 1, and,

Figs. 5 and 6 are perspective views of the supporting rings for the table standard.

Referring more in detail to the accompanying drawing, the reference numeral 10 designates the base of a table which may be secured in a suitable manner to a floor or other support indicated at 11, the base 10 being provided with a centrally-disposed standard 12 which extends upwardly a desired distance and is hollowed out to provide a receptacle-like structure 13 which constitutes a housing for a pendulous weight carried by the table top. The receptacle l3 Patented Apr, it), 1917..

has the vertical side walls suitably formed at their upper edges to receive the lower edge of a cone-shaped cover 14, the cover being secured to the upper edge of the receptacle 13 by suitable fastening means as at 15.

The cone-shaped cover 14 has a centrallydisposed opening 15 in which is mounted the universal mechanism for supporting the table top. As shown in Fig. 4, the top wall of the cover 14 is recessed to receive the ball bearings 16 to be engaged by the pins 17 carried by the ring 18. The recess and ball bearings are arranged on opposite sides of the opening 15 and constitute bearings for the said pins 17. In order to hold the ring 18 in fixed relative position, a retaining ring 19 is provided and has its inner edge engaging the pins 17 to hold the same in position and prevent the ring 18 from being removed, the retaining ring 19 being held in position by suitable fastening means 20.- EX- tending transversely of the ring 18 and supported thereby is a stub shaft 21, which is held in position by the locking ring 22 as shown in Fig. 6, ball bearings being also provided to reduce the friction between the ring 18 and the stub shaft 21. The ring 22 is notched'as at 23 upon opposite sides thereof to engage the ridges or projections 24 formed on the ring 18, thus preventing relative movements of the parts while the ring 22 is secured to the ring 18 by suitable fastening means as indicated at 25.

The table top 26 is secured to the plate 27 carried by the upper end of the standard 28, the standard 28 having the stub shaft 21 extending transversely therethrough and retained in such position by the locking pin 29. The lower end of the standard 28 is preferably threaded as at 30 to which is secured the pendulous weight 31. This weight is of such size and proportion as to always hold the table top 26 in a horizontal position in assembling the parts.

In operation, should the deck or other floor support 11 rock or assume a position other than horizontal, the weight 31 will move on its pivot support 21 held by the universal supporting rings 18 and 22, therebymoving the table top 26 so that the same will always assume a horizontal position, and prevent the upsetting of the articles supported on the table top.

The operation and construction of the device is extremely simple and in accordance with the showing, few working parts are re quired.

While we have shown and described the preferred embodiment of our invention, we do not wish to confine ourselves thereto as various forms, modifications and arrangement of the parts may be had without de parting from the spirit and scope of the invention as claimed.

What we claim as new is:

In a self-leveling table, a hollow base having an opening in its'upper wall, the said upper wall being removably secured to the base, a supporting ring having oppositely disposed pivot pins mounted in the wall of said opening with the pins resting in sockets in the upper wall, a stub shaft extending transversely of said ring at right angles to the pivot pins and loosely journaled therein, a retaining ring carried by the upper Wall for securing the supporting ring in position, a standard supported on said stub shaft, a pin extending through the shaft and standard, a table top carried by the upper end of said standard, and a pendulous weight carried by the lower end thereof and extending into the hollow base.

In testimony whereof we aiiix our signatures.
