CHARLES A. LEES, OF CHRISTCHURCH, AND STEPHEN \V. LESTER, OF SYDENIIAM, ASSIGNORS TO THE CANTERBURY (N. Z) SEED COMPANY, LIMITEIL-OI CHRISTCHURCH, NEW ZEALAND.

SEED-SHELLER.

SPECIFICATION forming part of Letters Patent No. 444,838, dated January 20, 1891. Application filed June 6, 1890. Serial No. 354,525. No model.) Patented in New Zealand January 9, 1889, and June 11, 1889.

T 0 all whom, it may concern:

Be it known that we, CHARLES ARTHUR LEES, of Christchurch, and STEPHEN \VIL- LIAM LESTER, of Sydenham, Canterbury, New Zealand, have made certain new and useful Improvements in Seed-Shellers, (for which patents were granted to us in New Zeal-and January 9, 1889, and June ll, 1889;) and we do hereby declare the following specification to be a full and clear description of the same, reference being had to the annexed drawings, making a part of this application.

This invention is a machine for the purpose of rubbing the husks off Yorkshire fog and trefoil seeds, in which a revolving brush or rubber of suitable material of conical shape operates in conjunction with a cone-shaped casing having concave projections on the inside, sothatthese seeds may subsequently by known processes be separated from other grass-seeds, a result which cannot be as well attained by means of such known processes alone.

This machine is also an improved machine for the purpose of rubbing the husks off clover-seeds, so that subsequently by known processes of separating or sifting the cloverseeds treated by this invention are mademarketable.

The invention consists in novel constructions and combination of parts, as will be hereinafter described and claimed.

In the drawings, Figure I isa vertical cross section of the apparatus, showing the connection with parts of the driving-gear. Fig. II is an elevation of the same. Fig. III is a detail of the oitwell bearing. Fig. IV is a detail of the brush. Fig. V is a detail of the collar which connects spindle with clutch. Fig. TI is a detailoi' thebcaring 0. Fig. VII is an enlarged drawing of the point of the punch, by which concave project-ions maybe made in the conical metallic casing.

Similar letters refer to similar throughout the drawings.

A is a cone-shaped brush or rubber, which is used with the smaller end down. The brush A is secured to a vertical spindle B, supported at its lower end by a collar L, resting in an parts oil-well K, attached as found convenient to a beam or other solid place, and also held in position in its upper end by a bearing 0, attached as found convenient to a beam or other solid place.

The con e-shaped brush A, in a machine used for shelling Yorkshire fog, trefoil,and clover seeds, when mixed with other grass-seeds, has bristles, preferably one and one-fourth inch long, of monkey-brass, or brass or any other brush material of a similar stiff nature, but in a machine used for shelling clover and trefoil seeds alone has bristles preferably one inch long, of wire, cane, or other brush material of a similar stiff nature.

The brush A is made to revolve in a coneshaped metallic casing C, (the small end d0wn,) having concave projections, preferably one-eighth inch square, on its inside, made by driving a punch of peculiar shape, hereinafter described, through the casing from the outside or by pins of the same size and description attached to the same, preferably four hundred of such punchings or pins to the square foot of surface. The ends of the bristles of the brush A should almost touch the ends of the projections or pins on the casing C, which projections orpins are placed vertically to the casing in a series of diamonds, as shown at C, Figs. I and II.

The metallic cone-shaped casingC has a close-fitting cap M and an opening D for feeding the machine, but is open at the bottom P.

E is'a flanged collar at the upperend of the spindle B, fitted with a working'collar R and clutch I which is coupled to an eccentric or crank Q, giving, preferably, three-eighth inchvertical stroke. Fitted onto the horizontal shaft G is a graduated pulley H is a pulley attached to the spindle I Fig. VII shows the point of the punch hereinbe'fore referred to in two views.

Mode of working: Belts from the motive power are passed over the pulley H and over the graduated pulley N, the brushA being driven round by the belts, preferably at a speed of two hundred revolutions per minute. The seeds beingfed in at the openingD make their way down between the brush and the outside easing O and there are rubbed by the l brush against the concaveprojections or pins l on the casing, which rubbing shells the husks off the seeds. By means of the belt over the cone-pulley N the shaft G is caused to revolve, and by the clutch and crank above described the brush A is raised and lowered while revolving. By this vertical movement the seeds are turned over at right angles to the direction in which the brush is movin", and are more thoroughly rubbed and made to fall more readily downward and out through the opening P, when they are subsequently cleaned by known processes. The speed of this vertical movement, preferably thirty-five revolutions per minute, may be raised by means of the graduated pulley N, as desired, and should it be found that the seeds are being rubbed too much the speed may be increased, thereby allowing the seeds to get out more readily at the opening P.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The combination, in a seedsheller, of a conical casing and conical brush therein, the

spindle B, having the collar E, the clutch F,

having the collar R, and the shaft G, having a crank Q connected With said clutch, whereby the brush is subjected to a circular and a vertical niovem ent, substantially as described.

2. The combination, in a seed-sheller, of a conical casing having punched projections therein, as described, and a closed top, a conical brush therein, its spindle and pulley thereon to rotate it, with a clutch connected to said spindle, and a crank-shaft connected to said clutch, substantially as described.
