DENNIS A. KELLOGG, OF VALPARAISO, INDIANA.

IMPROVEMENT IN HARVESTERS.

Specification forming` part of Letters Patent No. 116,601, dated July 4, 1871.

To all whom it may concern:

Be it known that I, DENNIS A. KELLOG, of Valparaiso, in the county of Porter and Stat-e of Indiana, have invented an Inqn'ovement in Harvesters, of which the following is a speciiication:

The object ot the present invention is to provide better means for holdingl and operating the sickle-bar; and its nature consists in the novel construction and arrangement otl a longsleeve which nearly incloses the driveshaft, a-nd rotates independently of said shaft in suitable boxes, the lower end of the sleeve terminating,` in a two-part case for suplmrting and protecting' the gearing' whichv operates the sickle-bar, as the whole is llereimtfter fully described and shown.

In the drawing, Figure .l is a perspective representation ot' a harvester with my improvement attached; Fi 2, an inverted view ofthe same; Fig. 3, the sleeve, drive-shaft, sicklcbar, and sickle-guard, the top part ofthe two-part case being removed to show the gearing inside; Fi 4, a transverse section ofthe two-part case, also showing' the sickle-guard and other parts appertaining' thereto, Fie'. 5, a perspective view ofthe under side of' the upper part of the gearing-case.

A l) C it F represent the trame-work of the harvester' mounted on wheels Q (L), in the ordinary manner, no particular form of frame bein g' required, only so that it be made to support the gearingy hereinaiter described. This gearing' is similar to that used in other harvesters, consisting' of a drive-wheel, l, Yfastened to the axle-tree G, a pinion, e, and bevel-wheel j" fastened to al shaft, II, the bevelwheel j driving' the. pinion c attached to the upper end ot' the drive-shaft d. This shaft isprovided with asuitable bearingl in the upper end of a rock-box, l), which is hung to the shalt H, and with a lmaringI in the case M S, as shown, by box W. Y represents a lon sleeve, which nearly covers the shaft d, and is arranged to turn i1ldependentlyr of' said shaft b v means of a box, q, attached to the lower end oi.' the rockbox l), and by means of the box W aforesaid, a collar, X, bein g formed on the upper end of the sleeve to hold it in place. The sleeve Y terminates at its lower end in the lower part S of a gearing lase, which is provided with a broad seat, L, to support the sickle-guard H', said seat holdingl the guard firmly in place so as toV withstand any (,)rdinary strain to which it may be subiected. The lower end of the shaft d sup ports a crank-wheel, 7.', which, by means of a crank, U, pivoted to said wheel at V, drives the sicklebar N in the` usual manner. To protect tho gearingI k Ul a cap, M, is so formed as to t the part S, leaving place p for the c 'ank U to work. By this means the shaft d. is not disturbed by turning the sickle-guard H into position for use, as shown at Fig'. l, or by turning it over, as shown by dotted lines Z, Fig'. 2, while `t the same time the leverage secured bythe long sleeve Y allows the sickle-bar to be readily f` raised and lowered when the harvester has a for ward movement, which is not the case when the sickle-guard is hung to the shaft d, as is eustomary. The means for raising` and lowering the sickle consists of a chain, a', attached to band l, run over a pulley, b', and fastened to a lever, l), and the means ii'or turning the outer end oi" the sickle upward or over back consists of a chain, ll, (fastened to a lever, g, Figs. 1, 3,) run over a pulley, l?, and attached to a lever, a, the lever b being brought forward to raise the sleeve and the lever c brought backward to raise the sickle.

I cla-i111- Iu combination with the rocking tubular dragbar, as described, having' the crank-shalt passing through it, the shoe S and the covcring-plate M, constructed as set forth.

A DENNIS A. KELLOGG.
