-PATENTED JAN. 29, `1907` POR THE: LEGS 0F BILLLARL TABLES AR ARTICLES. rLBD come 's-IMIIL APPLICATION W S .IINIVE-RSALLY ADJUSTABLE FOUT AND STATES rarnur cierren WALTER S. FERNAU, OF JAMAICA, .NET/V YORK. UNlVERSALLY-ADJUSTABLE FOOT FOR THE LEGS OF BILLIAD-TABLES AND SIMILAR ARTICLES.

To LZZ whom zt'ma/y concern:

Be it known that l, WALTER S. FERNAU, a citizen of the United States, and residing at Jamaica, Long Island, in the county of Queens and State of New York, have invented certain new and useful Improvements in Universally-Adjustable Feet for the Legs of Billiard-Tables and. Similar Articles, of which the following is a specification, such as will enable those` skilled in the art to which it appertains to make and use the saine.

rlhis invention relates to the legs ofbilliardtables and other articles of this class; and the object thereof is to provide an improved adjustable'foot for articles of this class by means of which any unevenness or inequality in the floor on which the table or article is placed may be compensated for and the table or article held in proper position at all times, a further object being to provide an adjustable foot which may be applied to porticoposts, piazza-posts, and other devices of this class and which in addition to affording at all times adequate means for adjustment will also prevent the rotting of the bottom of the post; and with these and other objects in view the invention consists in a device of the class specified constructed as hereinafter described angl claimed. A

The invention is fully disclosed in the followingr specification, of which the accompanying drawing forms a part, in which the separate parts `of my improvement-are designated by suitable reference characters, said drawing comprising a single ligure, showing in central vertical section the bottom part of the leg of a billiard-table and my improved universally-adjustable foot connected ehercwith.

In the drawing forming part of this specil ication I have shown at e a part of a Iloor over which al billiard-table is placed, and at b the bottom of one of the legs of a table, and in the practice of my invention l provide a base member c, which is concave on the bottom thereof and provided with a rim c2, adapted to rest upon the Hoor, and the base member c may, if desired, be secured to the floor -by screws or bolts d.

The base member c is provided with a central vertical bore or passage c4, the top of which is enlarged to form a semispherical cavity or recess c3, and in practice I provide the leg t with a metal bearing, washer, ournal, or other device e, having a vertically-arranged screw-threaded here e2, which com- Speeication of Letters Patent.

munieates with the the leg b.

Passing vertically through the member e into the leg o is a screw-threaded shaft f, the lower end portion of ball or spherical bodyfg, which rests in the recess e and is provided with a downwardlydirected trunnion or projection f3, which passes through the bore or passage c4 and is also slightly tapered to permit of the lateral motion of the shaft f, the bottom of which is provided with a washer or similar device f 4 lto prevent the shaft from being rwithdrawn from the base c.

That part of the shaft'fiinmediately above the ball or spherical body f2 is provided corresponding bore b2 in which may be passed a rod, bar, or similar device h, by means of which the shaft f may be turned, and in this way it will be apparent that by turning the shaftf any inequality or unevenness in the surface of the lloor may be provided. for, as may also any difference in the length. of the legs ofthe table, and in this way the table or other article maybe supported in a perfectly level position regardless of the condition of the lloor on which it is placed.

It will also be apparent that this'device may be used in.' connection with porticoposts, piazza-posts, and other devices or articles of this class, and in addition to provid- )l ing means wherebv the exact height of such posts may be regulated and maintained, my

. improved adjustable foot also, as will be unl derstood, prevents the said posts from rotj toning at the bottom thereof. My improve- I ment is also applicable for many purposes l other than thoseherein-speci'fied, and changes I therein and inodilications thereof may be made without departing from thev spirit of my invention or sacrificing its advantages.

llaving fully described my invention, what l claim as new, and desire to secure by lietters Patent, is-

I. A universally-adjustable foot .member -for the legs of tables or other articles, comprising a base having a semispherical recess in the top thereof and acentral bore extendl ing downwardly through said base from said recess, and a screw-threaded shaft provided with a spherical portion adapted to fit in said recess and having a depending tapered projection which passes through said bore.

I 2. A universally-adjustable foot member which is provided with a` with a transverse bore or passage g, throughy TIO forthe legs of tables or other articles, ceinprising a base having a semispherical recess 1 in the top thereof and a central bore eXtendl, ing downwardly through said base from said recessand a screw-threaded shaft provided with a spherical portion adapted to it in said recess and having a depending tapered prol jection which passes through said bore, said l depending tapered projection being provided with a head which is secured thereto and the bottom of the base being concave.

3. In an adjustable foot-piece for the legs of tables or other articles, a base member having a co'ncave bottom side and a semispherical recess in the top thereof together with a entral bore which extends from said recess to the bottom 0f said base, a screw-threaded shaft provided with a spherical body adapted to rest in said recess and having a central downwardly directed tapered projection which passes through said bore and is proyidcd at its lower end with a detachable 18a' In testimonT that I claim the foregoing as l my invention I have signed my name, in presence of the subscribing witnesses, this 8th day of October, 1906.
