SAMUEL FAHRNEY, OF BOONSBORO, MARYLAND.

SEPARATING GARLIC FROM WHEAT.

Specification of Letters Patent No. 2,835, dated October 26, 1842.

To all whom it may concern Be it known that I, SAMUEL FAHRNEY, of Boonsboro, Washington count-y, State of Maryland, have invented a new and useful Machine for Separating Garlic, Smut, and other Impurities from \Vheat, which is described as follows, reference being had to the annexed drawings of the same, making part of this specification.

Figure l, is a perspective view of the machine, Fig. 2, is a horizontal section through the spring bars &c., Fig. '3, is a vertical transverse section, Fig. 4, is a section showing the finger 0 saw plate, key, &c., Fig. 5 top view of the saw plate H,bars G, G.

Similar letters refer to corresponding parts.

The nature of this invention consists in passing the wheat and garlic over inclined yielding surfaces, which surfaces shall have a pressure, by means of springs, on the grain &c. suflicient to mash the garlic, or force it into cavities but shall yield to the wheat and allow it to pass without disfigurement, and then by means of scrapers, or fingers, distributing the two in separate boxes.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

I construct on any suitable platform or floor A a box or hopper B for receiving the grain to be operated upon. This box has three sides and a bottom firmly secured together in such a manner as to form in its horizontal section an equilateral triangle with one apex taken ofi, thus leaving an opening at the apex of one angle. In front of this opening is arranged a vibrating timber C, which rests and vibrates horizontally, on the edge of a horizontal board I) and in mortises, made in two vertical posts D, which posts are mortised and tenoned into the platform or floor A and arranged in a parallel line with the vibrating timber C, and a suitable distance apart. This vibrating timber to render it more durable, is lined on the face toward the triangular box with steel or iron E, and moves flush with the side timbers of the box B, to prevent the grain escaping at any other parts than through the channels F. On the steel face E is made a longitudinal channel F the full length of the steel facing, in width equal to the width of a grain of wheat and about twice the depth, in the bottom of which midway between the two sides of the channel, are secured on a line with each other, three ribs, or iron plates G, G, H, of the same length when put together as the vibrating timber C, and in thickness equal to one third the width of the channel, and about one half the depth of said channel. The center plate, which is 6 inches in length, has a number of saw teeth formed on its front edge, and is secured by means of a key I driven on the opposite side of the it when pressed forward, as it wears from constant use. A horizontal oblong mortise J is made in each of the sides of the triangular box B, which extends from the outletfo to the inner side of the side piece 79. Each rib, or saw plate H by means of an elliptic,

spiral, or semioval formed wire spring 8- which is made to press against it and which is regulated in its elastic force by a slide T placed behind it and against which one of its extremities rests. formed on the side of each of the vibrating bars which rests against the front of the A shoulder or stop .9 is V box L, when the spring is extended, to prevent it touching the edge of the vibrating rib or saw plate H; the end of this bar, which comes against the face or edge of the saw plate H to form with its longitudinal line an angle of about 65 degrees, is of an oblong shape, and forms a right angle with its longitudinal line. On each side of the outlet of the triangular box, and flush with the steel face of the vibrating timber is arranged an oblong box L, partitioned 01f longitudinally into two apartments, P, Q, the one P next the out-let for the reception of the wheat, after being separated, and the other Q for the garlic, the sides of these apartments, next the vibrating timber being entirely open. In the face of each of the partitions M that divide the apartments P, Q, is fastened a scraper or finger N, which projects in the channel sufiiciently far as to almost touch the top of the bar, or saw plate H and which being of the same thickness as the channel F is wide, will prevent any grain that remains above, or outside the surface of the bar and saw teeth passing, and direct it to the before mentioned apartment P of the 65. vibratlng timber, which key is for fastening one on each side of the bar or saw plate and be directed to the apartment Q of said box.

The vibrating timber C receives its vibra-" tory movement from a pitman rod T fastened to a crank shaft, which may be secured in any suitable frame.

Inside the triangular box and near the outlet thereof, is arranged a vertical shaft R turning in a step at the bottom and supported by a cross timber U at the top, extending across the top of the triangularbox B and covering the tops of the boxes L L and fastened thereto. On the lower part of this shaft are formed a number of cogs for agitating the grain and drawing it toward the outlet. Near the top of this shaft is fastened a spur wheel or pinion which works i in with a rack WV fastened on the top of the vibrating timber, and from which the wheel the apartments P of the boxes L and the receives its motion. 7

the one described.

Only one set of spring bars, fingers, one i channel saw plate &c., is described but sev- E 'eral sets 'inay be arranged on the face of the vibrating timber &c., in a similar manner to i the fingers or scrapers N, to the apartments P of the oblong boxL,and t-he garlic, (which remains below said surface) will be by means of the fingers 0 directed to the apart nents Q of said box L,and theve'rtical shaft .R with the cogs formed on itbeing turned by therack and .pinion V, will draw the grain inside the triangular box toward the outlet 0 to supply the place of the grain taken through the channel 'F.

What I claim as my invention and which 1' I desire to secure by Letters Patent is- The above described mode of separating garlic from wheat, by means of the saw teeth, tormedpn the edge 'of the plate H, and spring bars for mashing the garlic, and fingers N, O, for directing the wheat into garlic into the apartments of said boxes or any other mode substantially the same,

and in combination therewith, the hopper B aria-aged and construct-m s described,
