Specification of Letters Patent.

Patented Mar. 19, 1918.

Application filed June 6, 1917. Serial No. 173,206.

T 0 all wk-0m it may concern:

Be it known that I, JOHN Gnnnnno, a citizen of Italy, residing at Juneau, Territony of Alaska, have invented new and useful Improvements in Self-Leveling lables, of which the following is a specification.

This invention is an improved self-leveling device such as a table for use on a ship, a gun platform, or other structure which it is desirable to keep level when a ship is in a sea wave, the object of the invention being to provide an improved self-leveling table or device of this character which is simple in construction and which may be readily lubricated.

he invention consist in the construction combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings Figure 1 is an elevation of a self-leveling table constructed and arranged in accordance with my invention.

Fig. 2 is a detailed sectional view of the same.

My invention is here shown as embodied in a self-leveling table for use on a ship but I would have it understood that the invention may be embodied in a gun platform, a floor or other tructure within the scope of my invention.

A base 1 is provided which is here shown as conical and which in practice is preferably made of heavy sheet metal and is provided at the lower side with an outwardly turned flange 2 which may be readily secured on a floor or deck by screws or the like, the said flange being provided with openings for the screws as shown. A man-hole is provided as at 3 to enable repairs to be readily efiected. At the upper end of the base is a ball 4 which is mounted for universal movement in a socket 5 which socket comprises a lower member 6 and segmental upper members 7. The upper members are bolted together at their ends as at 8. The lower and upper members of the socket are respectively provided with outwardly turned flanges 9, 10. Bolts 11 engage openings in said flanges and serve to securely and detaohably hold the members 7 on the member 6.

The table, platform or other structure 12 which is to be kept level is provided at the center with a standard 13 which is screw threaded and downwardly through and engages a central threaded opening in the ball. A weight 1 1 which is here shown as conical has a central threaded opening in which the lower portion of the standard is engaged. The upper end of the weight bears against the lower side of the ball and the standard is adjustable vertically to raise or lower the table or platform and the weight is correspondingly vertically adjustable on the standard to permit of such adjustment of the table or platform. To secure the weight against the turning on the threaded standard I provide a lock pin 15 which passes an opening in the weight and engages the thread of the standard. In practice the screw thread of the standard is square to facilitate the engagement thereof by the looking pin.

Brackets 16 are at the other end of the standard and bear under and secure the table or platform. The upper portion of the standard has a vertical bore 17 at the lower end of which are radially arranged bores 18 to convey lubricant to the coacting surfaces of the ball and socket joint. A tank 18 of suitable size for the lubricant is counter-sunk in the center of the table or platform and supplies th lubricant to the bore or duct 17 as will be understood.

'While I have herein described and shown a preferred form of my invention, I would have it understood that changes maybe made in the form, proportion and construction of the several parts, without departing from the pirit of my invention and within the scope of the appended claim.

Having thus described my invention, I claim In a self-leveling structure of the class described, a conical base, a ball, a socket element at the upper end of the base and in which the ball is fitted for universal annular movement, a standard extending through conical Weight bearing directly against the V and engaginga threaded opening in the ball, lower side of the ball to prevent casual 10 a table or the like secured on the upper end turning of the screw and table and being of the standard and a conical weight having provided with means to lock the weight threaded engagement with the lower end of against turning movement on the screw the standard, coactingtherewith and with standard. V the said ball and socket member topreserve In testimony whereof,'I aflix my signature. 15 the level of the table or the like, the said JOHN GARNERO.
