SPECIFICATION forming part or Letters Patent no. 463,004, dated November 10, 1891. v

Application filed February 5, 1891. Serial No. 380,358. (No model) Toall whom it may concern.-

Be it known that'I, LEyI STEVENSON, a citizen of the United States, residing at Lewis town, indtiie county of Fulton and State of Illinois, have invented certain new and usefulImprovements in Self-Waiting Tables; and I do hereby declare the following to be afull, 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.

, My'invention consists ina new arid improved Iself-waiting table, which will be hereinafter-fully described and claimed.

Referring to the accompanying drawings,

Figure 1 is atop plan view of my new and improved self-waiting table.v Fig. 2. is acentral vertical sectional view of the same; Fig. 3 is a top plan View with the movable center ofthe table removed. Fig. 4 illustrates in' deac tail'one of the legs.

The same numerals of reference indicate corresponding partsin all the figures.

Referring to the several parts by their designating-numerals, 1 indicates the legs of the table, of which four are employed. Theup-.

per ends of these legs, which are formed, as shown, with the four wide faces 2 and the one narrow face 2, are arranged with the narrow faces 2'" outward, as shown in Fig. 3, and are connected at their upper ends by the horizontal boards or pieces The upper ends of the corners 2 of the legs which face inward are recessed to form the seats 4, on which rest and are secured the ends of two cross-pieces 5 5, which cross at their centers at right angles. Upon the narrow outer faces 2 of the four-legs are secured bracketsfi, the upper ends of which lie flush with the upper ends of the table-legs. The outer stationary part of the circular tableis formed of four curved sections or Segments 7, the straight ends of which meet in a close jointon the top of the table-legs on a line with the centerof the said Y legs, the cross-pieces 5, and theouter brackets 6, these brackets thus serving to support firmly the outer part of the joints, rendering the stationary annular part of the table firm and solid. The upper edges of thehorizontal pieces 3 are formed with deep recesses 8, in which are mounted the bearingwheels 9. These wheels consist each of a grooved wheel,

in the deep groove of which a rubber ring is seated, the wheel being pivoted in a fork 10, the lower end of which is formed with a screw 10. The wheels are thus secured in the recessed pieces 3 by screwing the screws 10 .into the pieces 3 within the recesses 8 when the wheels 9 project up sufficiently far to receive and support the revolving center of the table.

11. indicates the circular revolving center of the table, to the center of the under side of which is secured a hard-wood block 12, having a bearing recess or hole 12, in which fits a pivot-pin 13, which is secured on the center of the cross-pieces 5. This pivot-pin merely serves as a guide-pin to keep the centerof the revolving center 11 at the center of the.

table. The revolving center 11 rests near its outer edge and is supported upon the rubbertired wheels 9, and the circular edge of this part 11 is formed with an annular recess 14 on its upper side, thus forming an annular edge flange 15. The inner edge of the secf flange 17 of the stationary outer part of the table will hold the revolving central part in place-at all times, so that the table can be" handled at all times like an ordinary solid table in packing or shipping and in transporting it from place to place, permitting of its being turned over oh its side or upside down, as the under flange 15 of the revolving center fitting under the annular flange 17 of the stationarypart 7 will hold the revolving center in place at all times. The center 11 is provided near its outer edge with the series of knobs 18, by means of which it can be easily and conveniently turned. 1

From the foregoiugsdescription, taken in connection with the accompanying drawings, the construction, operation, and advantages too of my new and improved self-Waiting table cured to the outer face 2 of the four legs, the

will be readily understood. It Will be seen outer stationary portion of the table formed 20 that the revolving center will move with great of four sections or segments 7, recessed to ease and with the minimum of friction, and form a flange 17, beneath which the edge 5 that the entire table is very light, strong, and flange of the revolving center 11 projects, the durable. knobs 18 near the outer edge-of the revolving Havingthus described lnyiuvention, WhatI center, the horizontal pieces 3, formed with 2 5 claim, and desire to secure by Letters Patent, deep recesses 8, and the bearing-wheels 9, conis f sist-ing each of a grooved wheelin the groove 10 The combination of thelegs 1, the upper of which is seated a rubber ring, substanends of which are formed with four wide tially as specified. faces 2 and a narrow face 2, arranged with In testimony whereofIafiix my signatureiu 30 the narrow face 2 outward and connected at presence of two Witnesses. their upper ends by the horizontal pieces 3,
