IMPROVEMENT lN ATTACHING THE CONNECTING-BAR TO THE CUTTERS 0F HARVESTERS.

Specification forming part of Letters Patent No. E 3.! 76, dated July 3, 1855.

To all whom it may concern.-

Be it known that we, JAMES LITTLE and WYLIE LITTLE, of Princeton, in the county ot' Gibson and State of Indiana, have invented a new and Improved ltIowlng-ltlaehiuc; and we do hereby declare that the followingr is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a front view ot' our improved machine, the driving-wheel being bisected vertically through its center. Fig. 2 is a plan or top view ot the same. Fig. 3 is a frontview of a portion of the sickle. Fig. 4 is a plan or top view of the saine. Fig. 5 is a side view of one ot' the ngers, the linger-bar to which the iingers are attached being bisected transversely. Fig. Gis an inverted plan of three of the liugers attached tothe linger-bar.

Similar letters of reference indicate corresponding parts in the several figures.

Our invention consists in the peculiar manner of attaching the pitman or connecting-rod to the sickle-bar, as will be hereinafter shown and described.

To enable others skilled in the art to fully understand and construct our invention, we will proceed to describe it.

A, Figs. l and 2, represents a `metallic bar, having bearings a a, on its upper surface, in which the axle b of a driving-wheel, B. works.

The driving-wheel B is placed loosely on the.

axle b, and O is a wheel, which is permanently secured on said axle. The wheel C is somewhat smaller than the driving-wheel B, and it joins 0r works by the side of a circular rim, c, on the arms of the driving-wheel. On the outer edge or surface of the wheel O there is secured a pawl, d, one or more. (See Fig. l.) The pawl or pawls catch against the edges of the arms of the driving-wheel B, said arms eX- tending a tritle beyond the face of the rim c. The inner end ofthe bar A is bent or curved, asclearly shown iu Fig. l, and the linger-bar D is secured by bolts d to the inner end of the bar A, said finger-bar being also bent, so as to bring a portion of it near the surface of the groove. (See Fig. 1.) j

E E E are ngers,any proper number being used, and attached to the finger-bar D. The fingers E are formed each of a single piece of metal, and have a longitudinal slot,c,in lthem, extending nearly to their front ends, as shown in Fig. o. The back parts of the slots` are rather wider than the front, so as to receive the bar I) and sickle-bar F, the teeth fot' the sickle working in the front parts of the slots. The lower edges ofthe fingers E have ledges or projcctionsg on their under surfaces, as shown in Figs. 5 and 6, for the purpose ot' keeping the sickle the proper distance from the surface ot' the ground. The finger-bar D is placed in the back parts ofthe slots cot' the fingers,and rivets h. pass through both the top and bottom parts ot' the lingers and bar D, as shown in Fig. 5, one rivet being shown by dotted lines. The back parts ot' the fingers E, both on the upper and the lower side ot the bar D, are in contact or join each other, (see j Figs. 2 and 6,) so that the fingers are kept iirm and prevented from working loose. The teeth f are attached to the bar F by rivets g', and suitable spaces areleft between the teeth, as shown in Fig. 4. One end of the bar F is provided with a cylindrical projection, l, over which one end of the pitman or connectingrod G is fitted. The projection t' is of slightly taper form, and the end of' the pitman is provided with a loop, j, which is tit-ted over the projection i, as clearly shown in Fig. 1, thus forming a simple and eiiicient connection. The` opposite end of the pitman or connecting-rod Gr is attached to the end of a lever, 7c, which is at the end of a small shaft, H,working in suitable bearings, l, attached to an arm, I, which is connected to the bar A. The shaft H has a small geared sector, m, upon it, (see Fig. l.) and this sector gears into a corresponding sector, u, on a shaft, J, which works in suitable bearings underneath the shaft H. One end ot' both shafts H J has au arm, K, attached to it, against the ends of which teeth or projections 0 on the side ofthe wheel (l act.

At the outer end of the finger-bar A there is attached, by a hinge or joint,.p, a track-clearer, L. (ShowniuFigslandl) This track-clearer, in consequence ot' the joint or hinge p, is allowed to pass over obstructions, and will rise or fall, accommodating itself to the unevenness of the ground.

M represents the tongue or draft-pole, attached to the arm I, as shown in Figs. land 2.

N is the driver-s seat, secured to a frame, O, said frame being attached to the bar A.

As the machine is drawn along the drivingwheel B, in consequence of the pawl d catching against its arms, rotates the wheel G, and the teeth or projections 0 act upon the ends of the arms l( K, the upper arrnK forces the sickle outward and the lower arm draws it in, and consequently a reciprocating motion is given the sickle, the connection between two shafts H J,to which the arms K K are attached, being` formed by the sectors m n. If the machine is backed, the sickle is not operated, because the pawl (Z does not in that case catch against the arm of the driving-wheel, and consequently thedriving-wheelwillturnloosely on its axle.

Byconnecting the pitman or connecting-rod Gto the bar F, as shown, the pitman may be readily detached from the bar, and the play or looseness-which is' soon occasioned by wear in the ordinary attachments is avoided. Our mode of connecting the pitlnan and bar is very durable, as'the cylindrical projection i forms a solid mass of metal for the loop j to work over, and the projection fi, being ot' conical or taper i'orxn, compensates for any wear that may be caused by friction.

Having thus described our invention, what we claim as new, and desire to secure by Let- JAMES LITTLE. VYLlE LTTLF.
