JOHN S. TRUXELL, OF GREENSBURG, PENNSYLVANIA.

IMPROVEMENT IN HARVESTERS.,

Specilicaton forming part of Letters Patent No. 136,1`i2g, dated March 1l, 1873.

. To all 'whom it may concern:

Beit known that I, JOHN S. TRUXELL, of Greensburg, in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Harvesters; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompa nying drawing forming part of this specification, in which- V Figure l is a plan view of the under side of the machine showing the front cut; and Fig. 2 is a similar view showing the rear cut.

Similar letters of reference in the accompanying drawing indicate the same parts.

This invention belongs to that class of harvesters in which the cutter-bar can be placed .either at the front or rear of the frame, the

front cut being considered best for mowers and the rear cut for reapers, as giving more room for the working of the automatic rake.

The invention has for its object to improve the construction of machines of this classain such manner that the cutter-bar can be transferred from one end of the machine to the other without change of otherparts of the apparatus save those immediately connected with the cutter-bar. To this end the invention consists in the combination, with a harvester-frame and cutter-bar, of a pair of jointed connectingbraces constructed so as to admit of shifting the bar from front to rear or from rear to front on simply inverting and reversing the braces, as I will now proceed to describe.

In the drawing, A are the braces aforesaid, the same consisting of two bars, a b, jointed together at c, and provided with prongs, d d', at their ends. B B are plates attached to the under sides of the front and rear cross-bars, C of the machine-frame, and cast with lugs e,

-each of which has a transverse orice, which orifices receive the prongs d on the inner ends of the braces'. The lugs h on the inner end of the ingerbar D have also transverse orifices which receive the prongs don the outer ends of the braces. between the lugs h, and their prongs d' eX- tend in opposite directions, and are therefore made to enter the holes in the lugs h by opening the braces. A suflicient opening of the braces for this purpose is effected by the insertion of the prongs d in the lugs e. The shorter brace a, as shown in the drawing, is always in line with the cutter-bar, and the longer brace b always inclined to it, whether the cutter-bar is at the rear end of the machine or at its front end. In the former case the bar b pulls on the cutter-bar and in the latter case it pushes it. The prongs are all held inltheir several places by merely passing a key through the c prong d of the brace b. y

To' shift the cutter-bar, all that needs to be done is to take out the key, slide the prongs d back or forward, according as the cutter is at the rear or front of the machine, unship the p ron gs d from the cutter-bar, invert and reverse the braces, connect them once more with the -lugs It and e, and insert the key again. The

pitman i shifts with the cutter, and is driven in either position by hitching it to the wheel k or a crank on the adjacent extremity of the long shaft E that runs from end to end of the machine, passing through the boxes B, and having a wheel or crank at each end. No other parts of the machine require the least change.

Having thus described my invention, what I claim is- The jointed-bars A combined with a harA vester-i'rame and cutter-'bar in the manner described, so as to allow the cutter-harto be placed either at the front or rear end of the These outer ends are placed g
