CENTER BEARING FOR T URNTABl ES.
EPZECIL'FZCAEION forming part of Letters Patent No. 349,956, dated September 28l 1886.
Application tiled June EB, 1886. Serial No. 206,480. (No model.)
To all whom. t may concern.-
Be it known that I, EDWARD SAMUEL, a citizen of the United States, residing inv Philadelphia, Pennsylvanimhave invented certain Improvements in Center Bearings for Turn- Tables, ol' which the following is a specifica` tion.
My invention relates to improvements in center bearings for turn-tables, lnore particularly for street'railways, the object ot' my invention being, first, to do away with the usual project-ing set-screw in the center; second, to provide for the ready application of oil tothe wearing parts.
In the accompanying drawings, Figure l is a plan view of the turn-table. Fig. 2 is an enlarged section on the line l 2, Fig. l. Fig. 3 is a view of the screw-key for adjusting the height of the table, and Figs. 4, 5, and G are detached perspective views of parts ol' the device.
A is the base-plate, having an annular rib, a, through which pass adjusting-screws a', for centering the pivot-block B, the top of which is hemispherical. In the sides are vertical grooves b, for the reception ofthe ends ofthe set-screws a', to prevent the block from turning.
D is the turn-table, in the present instance a casting, on which are either formed or secured the rails d.
On the under side of the turn-table D is a block, E, which is secured to the table D, so as turn with it, and yet allow the table to have a limited vertical movement independent of the block. In the bottom of the block is a socket for the reception ot' the hemispherical pivothead B, forming, in fact, a universal joint. Pins c are secured to the under side of the table D, and pass through holes in the annular flange e of the block E, these pins being preferably headed, as shown in Fig. 2.
In a threaded orifice in the center ot' the turn-table D is a screw-plug, F, adapted to the threads in the orifice. rlhis plug rests directly 0n the block E, and has in the present iustance a square socket, f, in which iits a square screw-key, g, having suitable handles, g', Fig. 3. By turning the screwplug F by means ol' the key the turn-table may be raised from or lowered toward the block E. IVhen thekeyg is removed, ailat disk, l1., having an extension, h', closes the socket in the plug F, and extends over the plug and is iiush with the top ol' the table D, thus preventing any street dirt or dust from gaining access t0 the interior oi' the bearing.
I utilize the center plug, F, and block E as oil-receptacles. I form in the block E an annular chamber, i', which is connected by passages j with the ball-andsocket bearing shown in Fig. 2. This chamber 'i is illed with oil through passages 7.' l.' in the block E and through the socket f and a small passage, l, in the screw-plug F, so that on removing the disk 7L oil may be poured into the socketf, the oil finding its way into the chamber through the passages 7c, and thence to the bearing.
I claim as my inventionil. The combination of the bearing-block B, table D, and block E, attached to the table, with a screw-plug, F, within and completely below the surface olfthe table D, and adapted to be turned by a key, substantially as set forth.
2. The combination of the bearing-block B and table D with block E, having an annular oil-chamber, i, and a plug, F, having a socket and passages in the plug, and block E, connecting the said socket with the top of the bearing-block, substantially as and for the purpose set forth.
In testimony whereof Iliave signed my name to this specilication in the presence ol' two subscribing witnesses.
