IMPROVEMENT lN TURN-TABLES.

Specification forming part of Letters Patent No. 135,101, dated January 21, 1873.

To all whom it may concern:

Be it known that I, JOHN ENRIGHT, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented a Turn-Table, of which the following is a specification:

The invention consists in a turn -table in two parts, constructed and applicable to each other as hereinafter described, so as to exclude dust and prevent choking. It also consists in forming a step and groove enlarged to receive lubricating material.

In the drawing, Figure 1 is a top view, partly broken out; and Fig. 2 is a central vertical section.

A in the drawing represents the whole device, formed in two parts, B G. On the top of the turn-table B are placed the rails in the usual manner, while on the bottom is an annular overhanging edge-flange, b, a smaller annular flange, b concentric therewith, and a central pendent spindle, b". In the bed 0 is an annular bearing-groove, 0, against whose bottom comes the flange N. In the bed 0 is formed a central hollow step, c, for said spindle V. D is a flange on piece 0, by which it may be fastened to stone or timber in any convenient manner. The step c for the spindle b and the bearinggroove 0 are so concaved as to readily contain sufficient oil or other lubricating substance to last for a considerable time. The flange b on the outside of part B effectually prevents any dust from reaching the bearing-groove 0, while none will be able to reach the step, since it is inclosed on every side. The annular groove-bearing C is, of course, intended to retain the rotary table B in or nearly in a horizontal plane.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A rotary table, B, having a spindle, b, rotating in a step, c, of bed 0, and a flange, b rotating in a groove, 0, of said bed, as and for the purpose described.

2. The step c and groove 0, enlarged so as to receive lubricating material to last, as described.

JOHN EN RIGHT.
