IMPROVEMENT IN CORN-SHELLERS.

Specification forming part of Letters Patent No. 122,749, dated January 16, 1872.

Specification describing certain Improvements in Gorn-Shellcrs, invented by DAVID Gr. WELLS, of Joliet, Will county, and State of Illinois.

them reliable and durable, and reduce their cost of manufacture; secondly, to the mode of constructing the shaker-screen, so that it shall bc light, yet strong and durable.

In the accompanying drawing, Fig. l is a side elevation of the sheller, with the front side removed in order to show the internal construction. Fig. 2 shows that end of the machine which is at the right hand in Fig. l. Fig. 3 is a plan; and Fig. 4L is the same, with the cover removed to show the parts below. Figs. 5, 6, 7, 8, 9, and l0 refer to details of the machine.

A A is the frame of the machine, and B the cover. C is the throat through which the corn to be shelled is fed into the machine. The ilan ge of this throat rests upon the cover B and is connected by its rear or lower edge to the flexible plate D by two adjusting-bolts, e e, passing through slotted holes d and y in the flange and plate, which serve to hold the throat C in its proper position, as shown in Fig. 3 of the drawing. The plate D acts as a spring to the throat G, with its tongue H imparting to it a vibratory motion when the machine is Vbeing operated. The general shape of this plate and flange is more fully shown in Figs. 5 and 6. The plate D is made of sheet-steel of suiiicient thickness to possess the necessary elasticity, which may be increased or diminished by changing the position of the adjusting-bolts which secure it to the throat C.

Vthe action of the grain.

.- out with the cobs.

The shaker-screen i is used for separating the corn from the cobs after it is shelled. It is made with sheet-iron sides and round iron cross-bars. A row of holes is punched through the sides near one edge to receive the crossbars. The sides are then folded lengthwise so as to present a thickness of metal opposite each hole, which prevents the cross-bars from moving endwise in the holes, as shown in Fig. 8, which is a cross-section on the line w y. About every sixth bar extends through both thicknesses of metal and is securely riveted, which holds the whole iirmly together. It is desirable that the shaker-screen be made Wholly of iron, as Wooden sides are soon Worn away by It is also desirable that they be as light as possible consistent with strength, as a heavy shaker-screen absorbs more power and racks the machine more than a light one. These desirable qualities are obtained by this mode of constructing the shakerscreen. It is suspended by links j lc in the usual way, or by a strip of steel, a, Figs. 9 and 10, which also acts as a spring. It is worked by a cam, l, on the shaft of the dish-wheel u. The corn is prevented from going out with the cobs by the screens p p. The partition-plate r prevents the picker-wheel from carrying the corn` The blower o is driven by a belt from the periphery of the ily-wheel w.

I claim as my inventionl. The combination of the iiexible or springplate D and throat C, substantially as and for the purpose hereinbefore set forth.

2. The shaker-screen i, constructed as described, and for the purpose hereinbefore set forth.
