COCKLE-SEPARATO R.

`SPECIFICATION forming' part of Letters Patent No. 293,039, dated February 5, 188.4.

q Application filed October 17, i883. (No model.)

full, clear, `and exact description.

Reference is to be had to the accompanying drawings, forming part of this speci ticati on, in which the same letters of reference indicate corresponding parts in both the figures.

Figure 1 is a sectional elevation of my new and improved cockle mill and grader, and Fig. 2 is a plan view of the saine.

This inventionpertains to improvements in cockleseparators, and it consists of the several combinations and arrangements of parts, substantially as hereinafter fully set forth and claimed.

Referring to the drawings, A represents the inclined bottom of the cockie-separator. On this are secured the side boards, B B, and cleats C C, upon which are securedthe upper and lower plain cross-bars, D D, and intermediate grooved cross-bars, E, thusforming the space F, in which the cockle-seed falls from the screen G, which is secured upon the crossbars D E. The cockie-seed nds its way out of the separator throughnthe opening H, made near the lower end of bottom A,the passage or space F being 4closed just below this open ing by the partition I.

The screen G iscomposed, practically, of a series of short screens, g, with the detents or receptacles g', formed between them for retain-` ing in cach a small body of grain. These detents are formed by making a V-shaped gutter in the upper surfaces of the cross-bars E, and to bend the screen G down` into and secure it in said gutters, as shown in Fig. l.

Upon the forward inclined sides ofthe V- shaped receptacle g, I place the plates h, of sheet metal, which are slightly curved downward at their outer edges, as shown at t', the plates being for the purpose of giving the grain a smooth transit from the receptacles to the screens g.

At the upper end ofthe separator is secured to the upper cross-bar D and betweenthe side lboards, B B, the hopper J, to which the grain is fed in the operation of the separator. The separator is held in inclined position by the legs K K, which are attached at their upper ends to the side boards, B B, and are tied together by the' rod L, for steadying the legs and the separator.

In operation, the grain will be simply fed to the hopper J, whence it will flow down over the screen G. In passing the receptacles g', a portion of the grain will be retarded or retained in them, which in turn will retard and agita-te the grain that iiows on, thus giving the small cockie-seed time to settle down to the screen G and to pass through it, which it would not do so effectually if the receptacles g were not used. v

Constructed in the` manner described, the separator is very cheap and simple 'and very effective in use, and is adapted for all kinds of grain, and is rapid in operation and will not clog.

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

1. In a cockie-separator, the inclined connected series of screens g, having the detent-s y', in combination with the series of trans versely-arranged V-shaped-guttered bars E, within which the said detentsare located, sub-V stantially as and for the purpose set forth.

2. In a cockleseparator, the inclined series of screens g, provided with detents g', having the imperforate smooth-faced plates 7L, secured to the lower or forward sides oi' the detents, in combination with the series of transverselyarranged V-shaped-guttered bars E, substautially as and for therpurpose set forth.

3. The cockie-separator herein shown and described, comprising asuitable inclined bottom and side boards and the crossbars D D and guttered cross-bars E E, and the screen G, held in the gutters of the cross-bars E and provided with the plates h, substantially as and for the purposesset forth.
