GROUP XXIII. Si 159. Treman, Valentine, & Green, Ithaca, N. Y., U. S. HAND CORN SHELLER. Report.—Commended for strength of construction, simplicity, and efficiency, separating the com from the cob by double feed, and also separating chaff, etc., from the grain and cobs by small winnower. 160. Huber Manufacturing Co., Marion, Ohio, U. S. REVOLVING RAKE AND HAY COLLECTOR. Report.—Commended for the improvements over the old collectors, viz., working on iron and being held in position by an iron spring; also for a jointed arrangement which allows of its being folded up and readily transported. The action of the spring, aided by the intelligence of the operator, secures the operating teeth being kept at a proper angle. The handles are kept rigid by a tie rod. They are connected to the frame by a secure bearing. Though hardly a hay rake in the proper sense, as it cannot rake uneven land clean, it is very useful for cutting hay into rows with rapidity, and has one great merit, viz., low price. 161. J. R. Fitzhugh, Philadelphia, Pa., U. S. HAY ELEVATOR. Report.—Commended on account of its simplicity and its cheapness. This is a traveling pulley running on a bar and intended to be attached to a hay fork for the purpose of un loading hay or straw from a wagon; when the load reaches the desired point it is stripped by a cord and the load is discharged from the fork, and the device and fork are returned over the wagon by a weight. 162. D. M. Osborne & Co., Auburn, N. Y., U. S. HARVESTER AND AUTOMATIC BINDER. Report.—Commended as a highly successful attempt to introduce a much-wanted labor- saving harvester. The mechanism by which the binding is effected with wire is simple and efficient, as proved by the fact that during a somewhat protracted trial there was no failure or stoppage. The sheaves can be regulated as to size by foot leverage, or the action may be continuous. The tension on the spool is equal whether full or empty, by means of a screw and strap pulley. The binding arm which regulates the direction of the wire is jointed, and has an ingenious and effective swan-neck motion. The binding platform can be made to slide backwards or forwards to regulate the position of the band according to the state of the crop. 163. David Kahnweiler, New York, N. Y., U. S. COTTON-SEED HUI.LER FOR PLANTATIONS AND OIL MILLS. Report. Commended as being well made and thoroughly efficient, supplying an increasing want on cotton plantations, viz., by a means of preparing the cotton seed by the removal of shell and the cotton left by the gin, to be made into a highly valuable food. The mechanism is simple and the result satisfactory. Thus, the feed roller insures regular sup ply and prevents passage of nails, sticks, and other foreign matter that would injure the mill. The under roller has a smooth surface, carrying eight knife-sections so arranged as to follow each other like a screw; they are easily regulated to compensate for wear. The gin has four knives. The shell and seed fall into a fine reciprocating screen, being dis turbed and distributed by a revolving spindle furnished with wooden teeth. The hulls are carried over the screen. The seed falls through the screen, and is received at a box screen, which, being properly agitated, separates the lighter portions of the hulls which have passed the wire screen, getting rid of them over the apron. Larger machines are made for man ufacturers. 6
