IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 32,267, dated May 7, 1861.

To @ZZ whom, it may concern:

Be it known that I, J AMES PINE, of Troy, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Grain and Grass Harvesters, (No. 2;) andI do hereby declare that the following 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 1 is a side elevation of my invention; Fig. 2, a plan or top view of thesame.

Similar letters of reference indicate correpending parts in the two figures.

This invention relates to an improved device for varying the upward draft applied to the nger-bar without changing the angle of the latter.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it. j

A represents an axle, on one end of which a wheel, B, is fitted and allowed to rotate freely. To this axle A a draft-pole, C, is attached, either rigidly or-by a joint. In Fig. 2 the draft-pole is shown as being rigidly attached to the axle.

D represents the gear-frame, which is con! nected to the axle A, orrather suspendedfrom it, by straps a a, the axle being fitted loosely in the straps, so that theilatter may work or turn freely on the frames.

To the front end of the gear-frameD the iinger-bar E is. attached, the grain end of which has a shoe, F, connected to it. The shoe F projects back of the finger-bar and has a grainwheel, G, secured to it.

The back part of `the draft-pole C has a lever, H, attached toit, and the lower part of the under side ofthe draft-pole C there is se;

euredby a staple or joint, j', a pendent perforated" bar, K, the lower end of which is a tached by a rod, g, to the front end of the gear-frameD, as shown clearly in Fig. l. To

this bar K the double-tree is attached, and n at a point higher or lower, as maybe desired.

From the above description it will be seen that the draft-pole C may be elevated or del If the wheel B be permanently secured to the axle A, and the latter' consequently turn with the former, the inner end of the draft-pole must be fitted loosely on the axle A by means of straps, so that the draft-pole may work loosely on it, and the result bethe same as if the wheel be loose on the axle, and the latter allowed to turn by the working of the draftpole. by attaching the draft-pole to the ge-ar-frame by ajoint at any point from its front end to its axle. The attachment of the draft-pole back of the axle would not answer, as the draft would have a tendency to force the fingen board into the ground. By this arrangement the difference in the height of teams will not affect the proper working position of the gear# frame and nger-bar, and the framing usually termed a main frame,77 to which the draftpole and gear-fra1ne are attached, is dispensed with, and a machine of light and easy draft obtained.

between the finger-bar and the draft-pole, and the draft will" have a tendency to keep the finger-bar slightly elevated7 so that it will skim lightly over the `surface of the ground and prevent unnecessary friction and consequent side draft. This tendency of the draft to elevate the sickle may be increased or diminished, as circumstances may require, by adjusting the double-tree higher or lower on bar K.

. The nger-bar is elevated, so that it may pass over obstructions,by drawing back lever H, the finger-bar being retained inanelevated state, in consequence of the pawl d engaging with the ratchet-teeth c. Vhen it is desired to release the finger-bar E, the driver simply presses down with his foot the back end of lever J, and the front end of said lever forces The same effect may also be obtained By having the draft connected `to the bar K, as shown, the former is divided upward thepaWl d and throws it out from the I and employed in connection with an adjustteeth c. 1 able double-tree t0 Vary the upward draft'ap- Having thus described my invention7 what plied to the ngenbar Without changing the I claim as new, and desire to secure by Letters angle of the said bar.

Patent7 isy JAMES PINE.

The combination ofthe perforated bar K and Vitnesses: link g, attached to the tongue C and geair- WM. B. LITOH,
