THOMAS A. JEBB AND \NILLIAM T. JEBB, OF BUFFALO, NEW YORK.

STARCH-TABLE.

SPECIFICATION forming part of Letters Patent No. 243,269, dated June 21, 1881.

Application filed May 12, 1881.

To all whom tt may concern:

Be it known that we, THOMAS A. J EBB and WILLIAM T. JEBB, of the city of Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Starch-Tables, of which the following is a specification, reference being had to the ac companying drawings.

This invention relates more particularly to that class of starch-separators which consist of slightly-inclined shallow pans or tables, over which the liquid containing the starch is caused to run, and upon which the starch is deposited, while the refuse liquid escapes. These tables frequently exceed a hundred feet in length, and are required to stand at the proper inclination lengthwise, and perfectly horizontal crosswise, in order to insure an even flow of the liquid over the tables. The position of these tables changes frequently in one place or another from numerous causes, more especially from the settling of the supports or the warping of the material from which the supports and the tables are constructed. A deviation of the tables from their proper position results immediately in an un even flow of the liquid and aloss of starch, because the starch is prevented from being deposited where the current is strongest, and the starch which fails to be so deposited is carried off with the refuse liquid and lost.

The object of this invention is to provide a simple device whereby the starch-tables can be readily raised or lowered, as may be necessary, to maintain them in their proper position and our invention consists of the particular construction and arrangement of the adjustingdevice, as hereinafter fully set forth.

In the accompanying drawings, Figure l is a cross-section of a series of starch-tables provided with our improvements. Fig. 2 is a longitudinal section thereof. Fig. 3 is a detached sectional view, on an enlarged scale, ofthe adjusting mechanism.

Like letters of reference refer to like parts in the several figures.

A represents a series of starch-tables of the usual construction, three or four of these tables being preferably side by side.

(No model.)

B represents two longitudinal stringers or girders, upon which each table is supported.

0 represents the cross-beams of the building, which rest on posts D. The tables A are arranged above the cross-beams C, and supported thereon by means of inclines E, secured to the cross-beams G, and wedges F, which are driven between the inclines E and the girders B. As shown in the drawings, the wedges E F are arranged parallel with the girders B,or at right angles to the cross-beams O, and form caps which afford a comparatively large bearing-surface to the girders B.

9 represents a set-screw, which works in a thread in the incline E and bears with its point against the lower surface of the wedge. A11 incline, E, and wedge F is arranged between each cross-beam O and each girder B, whereby the tables are supported at numerous points.

In order to raise or lower a table at any particular point the wedges F next adjacent to the point where the adjustment is required are driven in or out, as may be'necessary, after first releasing the set-screw 9. When the table has been adjusted as desired the set-screws are again tightened to prevent the wedges from slipping. By so adjusting each table separately the proper position of each table is readily maintained and the proper separation of the starch from the refuse liquid insured.

We claim as our invention 1. The combination, with supporting-beams G, ofa starch tableor tables provided with horizontal girders B and inclines E, and wedges F interposed between the beams (J and the girders B, substantially as set forth.

2. The combination,with supporting-beams G, ofa starch table or tables provided with longitudinal girders B, inclines E, secured to the supporting-beams O, and provided with set-screws g, and wedges F, interposed between the inclines E and the girders B, substantially as set forth.
