THOMAS A. JEBB AND WILLIAM T. JEBB, OF BUFFALO, NEW YORK.

STARCH-TABLE.

To all whom "it may concern Be it known that we, THOMAS A. JEBB and WILLIAM T. JEBB, of the city of Buffalo, in the county of Erie, in the State of New York,

have invented new and useful Improvements in Starch-Tables, of V which the following is a specification,reference being had to'theaccompanying drawings.

This invention relates more particularly to that class of starch-separators which consist of shallow trays, pans, or tables, and which are employed for the purpose of separating the starch from the gluten and other deleterious substances. These starch separators or tables are of great length, frequently exceeding a hundred feet, and they are required to stand at a slight inclination to permit an even flow of the liquid over the same from end to end, in order to effect the desired separation. The position of these tables changes from numerous causes, more especially the settling of the supports and the warping of the material from which thetables and the supports are constructed. A deviation from the true posi- 2 tion of the tables results immediately in an uneven flow of theliquid, and consequently in an imperfect separation and corresponding waste of starch.

The object of our invention is to provide a ready means for the adjustment-0t these tables; and it consists of the particular 0on truction of the mechanism whereby the tables e adjusted, as will be hereinafter fully set orth.

In the accompanying drawings, Figure l is a cross-section of a set of starch-tables provided with our improvements. Fig. 2 is an elevation, on an enlarged scale, of the means for adjusting the tables. Fig. 3,is an elevation at right angles to Fig. 2. Fig.4is a top plan view of the adjusting mechanism.

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

A represents one or more starch-tables of the usual construction. Three or four of these starch-tables are preferably arranged sidev by side and supported upon cross-sills B by strin g- SPECIFICATION forming part of Letters Patent No. 256,221, dated April 11, 1882,

bears with its inclined upper snrface,f, against the correspondingly-inclined lower face of the shoe E. The wedge F slides on a horizontal keyway, G, which is secured to the beam H, and the wedge is actuated by a screw, 2', working in a threaded lug, I, cast on the keyway Gr.

The shoe E is guided vertically between two plates, J, which are secured to the post D, and which prevent the sills B and the tables resting thereon from moving lengthwise under the influence of the wedges, while permitting of the desired vertical movement of the shoes and the sills and tables connected therewith. The keyway G is provided on its upper side with a longitudinal rib, l, fitting in a groove, m, on the under side of the wedge F, and the latter is provided on its upper side with a rib. 'n, fitting in a groove, 0, in the under side of the shoe, whereby the shoe, wedge, and keyway are retained in the proper relative position.

By moving the wedge F in one or the other direction the end of the sill resting thereon is raised or lowered, and the portion of the table which is supported on the sill is correspondingly adjusted.

The adjusting devices are in convenient reach of the men who work on the starch-tables, and are readily operated by applying a suitable wrench to the screws by which the wedges are moved.

We claim as our in vention- 1. The combination, with a starch-table, of wedges F, resting on supports or ways G and engaging under plates or shoes E, and guides whereby the parts resting on the wedges are held against lateral displacement, but permitted to move vertically, substantially as set forth.

2. The combination, with a starch-table, ot'

ers O. The cross-sillsB are arranged between I wedges F, resting on supports or ways G and engaging under plates or shoes E, guides I the beams H, and vertical guides J ,between, to whereby the parts resting on the wedges are which the shoes E-slide, substantially as set held against lateral displacement, but perforth. mitted to move vertically and screws whereby the wedges are adjusted, substantially as set forth.

3. Thecombination,with one or more starch- Witnesses: tables, of cross-sills B, provided with'shoes JNO. J. BONNER, E, wedges F, horizontal ways Gr, secured to EDWARD VVILHELM.
