HENRY r.. JAMES, or TRENTON, NEW- JERSEY.

i surtir-MACHINE.

Specification `of Letters Patent No. 11,195, dated June 27, 1854."

To all whom may concern.'

Be it known that I, HEvRv` B. JAMES, of the city of Trenton, in the county of Mercer and State of New Jersey, have invented a new and useful Machine for Scouring and Cleaning Grrain,` called a Grain-Securing Separator, for Farmers and Millers; and I do hereby declare that the following is a full and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is an external View of the machine in its proper vertical position, Fig. 2 is a view of the shaft, fan, and a section of the roughened lining.

The case A (which contains the fan and the lining B, B) is airtight and inclosed beneath by an irregular funnel-shaped concave C, having an air passage and discharge flue D, near the center. The fan shaft E projects through the center of the concave and is supported by a step F, outside of the flue. The upper end is supported in asimilar manner. The lining B B, showing the inner surface) is sheet metal roughened by indenting and piercing the entire surface from the outside. As the grain may wea-r the inner surface it will continue to which the wings are secured; they arev caused to revolve by the pulley K, with the roughened surfaces acting on the grain within the case, by scouring and winnowing at the same time. The top of the case is inclosed and provided with an air` passage of a spiral form running upward L, M, on the out edge of the head and case, open beneath to receive the air `frointhe front of the fan wings. The highest end` M, is surmounted by a. f1ue with curves or offsets N, O, forming a spiral and zigzag air-passage over the scouring fan and air-tight case. lThe grain is admitted in as wide a sheet `as possible above the curve N and curve N and is `thus checked, and scattered,`

in its descent, the full discharge of air from the largev end of the spiral passage, and the fan, is forced up on the side of the flue out the end of the flue above in any desirable` direction, by the air. As the grain passes through the. dischargeflue D it is again winnowed by the air rushing in to supply the fan.v

Suitable screens may be suspended over ythe hopper P, in the usual Inode, or by springs of unequal stiffness, heavy ones being near the shaft; and which may be shaken without much jarring or friction by means of the eccentric R on t-he upper end of the vertical shaft of the fan, having a connection with the screens, or a shoe containing them, by a collar, slot, or bearing. A screen may also be placed under the flue D. This differs from a former machine patented by me May 17th, 1844, in the various particulars already described, one set of inclined wings is new in the combination and is more generally useful, being more compact and portable and will do the work with less power. l

A hand machine may be constructed with a case of cast or sheet iron 8 or 9 inches deep, 1S inches indiameter above and 14 below, the `concave C three inches deep, the Hue D 3 inches, with capacity 2 by 5 inches, the flue N, O; the same capacity, the width of the spiral L, 5 inches, the height at M 4 inches, the flue and the spiral uniting the widest way, the angle N, abouthalf w'ay between a vertical and a horizontal position, the fan wings about half that distance from a vertical position, and may be in either direction, the height from the curve N, to O, about 8 inches, the pulley 3 inches, weight of 3 or 4 ounce pieces added to each wing will have a tendency to keep up the motion while acting on the grain. No very sharp edges should be on them. They should curve backward at their extremities, and a space between them, and the case or lining should be about an inch and a fourth.

A suitable frame may be constructed for supporting the machineand the screens in a portable form; for a hand machine a- 9 Cil inch belt Wheel on a Vertical shaft is necessary, with a 3 inch bevel pinion onvthe shaft and a 12 inch driving Wheel on a horizontal shaft, with a crank, a belt passing around the lbelt Wheel and pulley, With the iiue standing Within it, between the Wheel and pulley. Eight hundred revolutions per minute are required for Wheat and siX hundred Jfor buckWheat. The eccentric may be made by turning down the end of the shaft about one inch in length, With the shaft one Y fourth of an-inch out of center.

Having thus described my buckWheat and smut machine and grain separator, I do not claim, separately the parts herein specified, but

What I do claim is.

The combination of the hopper P, trunk N, spiral passage L, and separator O, effected by means of a common air-tight vcasing in the manner, and for the purposes set forth.
