TAB LE-LEVELER.

SPECIFICATION forming part of Letters Patent No. 563,241, dated June 30, 1896.

Application filed April 15 1896. Serial No. 587,685. (No model.)

To all whom it may concern.-

Be it known'that I, BENJAMIN W'OOD, a citizen of the United States, residing at Richwood, in the county of Union and State of Ohio, have invented certain new and useful Improvements in Table-Levelers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in devices for leveling billiard, pool, and bagatelle tables and the like; and its novelty and advantages will be fully understood from the following description and claim, when taken in conjunction with the annexed drawings, in which- Figure 1 is a perspective view of one corner of a pool-table with my improvements applied. Fig. 2 is a vertical sectional view of one of the legs with my improvements in position thereon. of the bur or nut removed from the leg. Fig. 4: is a perspective View of the slidable sleeve or collar and Fig. 5 is a perspective view of the adjusting -screw, illustrating a wrench for manipulating the screw.

Referring by letter to said drawings, A indicates a pool-table, there being but a part here illustrated, and 13 indicates one of the legs, which is shown for the purpose of illustrating the application of my improvements thereto. The table may be of any suitable construction, the legs, as is usual, being of an angular form-in cross-section.

0 indicates a bur or nut, which may be composed of steel or other suitable hard metal, and may be made stout, as shown, so as resist such strain as it may be subjected to. I employ one of these burs or nuts on each leg of the table and preferably form the same with a flange a, having holes b to receive screws or other suitable fastening devices. Each bur has the projection 0, so as to extend the screw tapped portion and strengthen the same, and in placing these burs I recess the under side of the legs, as shown at d, so as to receive the portion a of said burs.

Fig. 3 is a perspective view D indicates the adjusting device, which comprises a screw e, designed to take into the threaded aperture f of the bur; and at the base of this screw is a head h, which is convex on its under side, so as to bring the bearing-point central of the screw and produce as little frictional contact with the floor or other suitable support as possible. This head is notched or cut out at suitable points, as shown at '2", to receive a wrench E or other suitable device for turning said head and screw in adjusting the table.

F indicates a sleeve or collar which is of an angular form in cross-section and is designed to play vertically on the table-leg. This sleeve is designed to fit the leg rather snugly, so that while it may move vertically it will be prevented from turning on the leg. The normal position of the sleeve is embracing the leg and concealing the screw and resting upon the head h of said screw. The sleeve is provided on one side with a hanger-arm j, which is here shown as fastened by bolts or the like, although it is obvious that the arm may be formed integral with the sleeve. The arm projects a sufficient distance below the lower edge of the sleeve and is provided with a transverselydisposed screw-threaded aperture Z to receive a wing-nut or thumb-screw m. The object of this thumb-screw is to fix the sleeve with respect to the adjustable screw.

In operation, when it is desired to adjust the table, the thumb-screw should be first disengaged from the periphery or edge of the head h. The wrench E is then placed in one of the seats in said head and the latter, with its threaded stem e, turned to either raise or lower the table. \Vhen the table has been adjusted as desired, the wrench is removed,

taking into the same and having the head contable, substantially as and for the purpose vex on its under side and provided with a set forth. :0 wrench-seat, and the slidable sleeve having In testimony whereof I affix my signature the depending arm screw-tapped and the in presence of two witnesses.
