CHARLES JORDAN, OF EAST BRIDGEWATER, MASSACHUSETTS.

.Lctters Patent No. 96,439, dated November 2, 1 869.

To all whom itmay concern Be itknown that I, CHARLES JORDAN, of East Bridgewater, in the countyof Plymouth, and State of Massachusetts, have invented a new and useful Machine for Hulling, Cleansing, Polishing, and Silting Berries, as coffee, rice, grains, 850., of which .the following is a full, clear,- and exact description, ref

erence being bad to-the accompanying drawings, in

which-- Figure 1 is a vertical longitudinal section of the machine embodying my invention.

Figure 2 is an end view of the same, with vertical cover-plate removed.

Figure 3 is a detailed view.

1 Figure 4 is a modification of the lmlling steel ratchetp ate.

The same letters refer to the same parts in the different figures.

The object of my invention is to produce a berryhulling, cleansing, and polishing machine, combining these three distinct operations in one machine; further, in'constructing a durable and strong hullingplate, which will wear well, and not be subjected tothe objections heretofore. made against, this diflicult part of machines of this kind, and which, in combination with other parts, efl'ectually removes the hull from the berry, withoutbreaking the latter.

My machine consists in the peculiar construction of the hnlling-plate, which may be made as a cast plate, corrugated upon its face, or reversible, that is, corrugated upon both its faces; or, as an eqnivalentconstruction, by square steel bars set into the bed-plate, so that one edge'ofa bar projects beyondthat of the succeeding one, said plate having a vertical reciprocating motion; and in a series ofelastio plates, which, with their corrugated or diamond-cut steel faces, being opposite to the hulling-platc, andbeing firmly secured to'a frame, receives a horizontal reciprocating motion, thus rolling and rubbing the berries between the hulling-plates, but by means of the elasticity of the latter,

preventing breaking the same, and still frees the herries coinpletelyfi'oin the luill or chaff.

Referring to the drawings- A is a frame of the machine, with closed sides and top, and open ends. At therear portion of it is placed an upright. frame or box, B, provided with three sides, and the front only partially covered by the board a.

At the rear of box -B are two stands,.b b, which support the shaft D, with crank (l. The latter acts upon two studs or arms 0 c, which latter, being firmly secured to the hulling-plate E, cause the latter, by the rotation of crank 11, to receive a reciprocating vertical motion in box B.

To one side of balling-plate E is attached the rack j, which, operating on pinion'F, communicates to the latter a vibrating motion.

Opposite the steel bars 9 g g of hulling-plate are an elastic serrated steel plate, It, and a series of elastic pads, i t i, the faces of which are either serrated, corrugated, or diamond-cut, turned toward bars g g g, and attached to'a movable frame, G,'in such a manner that they are held to frame G, by means of spring bolts, which make the pads yielding and elastic.

At the under edge of frame G is firmly attached the rack K, meshing also into pinion .F, and, therefore, receiving a recipmcating the oscillation of said pinion F.

The spring-bolts are held to frame G by cap g, which is provided with set-screws y y, and held by screw 2, for the purpose of adjusting for the differentsized berries.

Above elastic plate k, and also secured to frame G,

is the corrugated roller L, moving with the frame,

and being provided at one end with a ratchet-wheel, l, and spring-catch m. The purpose of this roller is,

that if any large berry or hard material should pass between the hulling-bars g g and roller L, the latter will be rotated, thus acting as a feed-roller, and preventing clogging of the berries. The spring-catch m prevents too free a motion of roller L.

'The apron 'n guides the berries from a hopper into the box B. I

Underneath box B, and close to the aperture 0, is, the mouth of fan-blower O and the endless band P, which carries the berries to the polisher Q, at the forward portion of the frame A.

The polisher Q consists of the cylinder 12, the surface of which is provided with a number ofstiti' brushes, which sweep against the corrugation of cylindrical shells It R.

Underneath the polisher is-the sieve S, placed at such an inclination as to allow the now cleaned berries to pass to the rear, to a vessel provided for their reception. I

On one end of shaft D are pulley U, and hand-crank or driving-pulley, for imparting motion to the movable parts of the machine from pulley U.

The belt passes around pulley T, on fan-blower shaft,

' to pulley V of polisher, and back again to pulley U, thus connecting and moving these three pulleys by one belt.

At the other end of shaft D is attached a pulley, W,-which imparts motion, by means of a belt-pulley, X, on roller 'r, to endless band P.

The operation is as follows: After setting the machine in motion, the berries will enter above apron 12., and drop between the bans g g g, roller L, pads It 1', t, where they receive a thorough scrubbing and working, the hul!s being completely separated from the kernel, and both drop down hrongh the orifice 0. At that point a' strong ourlent of air, issuing from the, fan, will blow the light horizontal motion, by

chaff above and along; endless belt I,

will drop upon and out of the whilst the body the belt or apron P, to be cariied to the polisher, where it is robbed and cleaned by the brushes, rotating within the cylindrical casing. From there the berries pass upon the sieve, the dusty, small, or broken particles falling through the same, and the now cleaned berry is carried alone into a proper ready for shippin".

It will be seen that the double reciprocating motion is accomplished by the simple application-of crank d, racks f and K, and pinion 1*.

Into the balling-plate, as shown in the drawings, is inserted a series of square, hardened-steel bars, in such a manner, that when the edgesshouldbecome 'dull, the bars may be turned and another edge pre sented for action; but} do not confine myself to the bars, as a steel plate, amen as shown in fig. 4, and reveisihle, so that the two faces can'come in action respectively, will answer the same"pnrp6se.

What-,1 claim as my invention, and desire to secure by Letters Patent, is-

aperture u at the end of the machine,

1. The combination of the yielding pads and bars 5 'i h with the vertically-reciprocatiilg balling-plate E, eccentric pin, 1!, and arms 0 0', when said parts are constructed and arranged as described.

2. The reversible balling-plate,shown in fig. 4, when constructed in the manner and for the purpose set forth-.-

3. The square steel bars 9 9, set into the: bed. of plate E, and placed one above the other, in combination with verticallyreoiprocating plate E, when constrncted and arrangedsubstantially as set forth.

4-. The reciprocating frame G, provided with adjustable cap g, in combination with the yielding pads and bars 'i 'i h, eccentric d, and are constructed and arranged as shown and described.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

CHARLES JORDAN.
