UNITED STATES PATENT OEEIGE.

IMPROVEMENT IN HARVESTERS.

Speeication forming part of Letters Patent No. 117,514, dated August 1, 1871 antedated July 21, 1871.

To all whom t may concern:

Beit known that I, CHARLES GLAPP, of Trumansburg, in the county of Tompkins and State of New York, have invented a new and useful Improvement in Harvesters; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing making part of this speciflcation Figure l being a plan of a harvester provided with my improvement; Fig. 2, a vertical section thereof in a plane cutting from front to rear.

Like letters designate corresponding parts in both figures.

The object of this invention is to eifect an im` provement especially in that kind of harvcsters shown in the drawing and described in the speciiication of Letters Patent of the United States granted to me bearing date the 10th day of May, 1870, and numbered 102,7 7 6, in which the cutting apparatus is made to rise and fall by having the inner shoe and grass-shield attached to or connected with a sleeve which turns or vibrates on a tube covering the crank-shaft of the cutterbar, and the invention is more particularly adapted to that kind of machine; and the invention consists in a flexible brace or brace-chain so connected with the pole, with the iiange which supports the ilmer shoe of the cutting apparatus, and the frame of the machine back of and below the main axle, as to relieve the said iiange and its sleeve from strain in drawing the machine, and to give support to the said flange when the machine is in motion, substantially as herein specied.

Let A A represent the driving-wheels of the harvester; B, the cutting apparatus, O, the grass-shield and inner shoe combined D, the

sleeve to which the latter are connected; E, the

flange on the side of the sleeve and forming the connection between the same and the inner s hoe 5 and l?, the pitman of the harvester. A casting,

F, forming atubularproj ection of a head or frame in which the axle G revolves, receives and forms the bearing of the crank-shaft. Forward of the axle this tubular projection F has the form of a skein, fitting inside of the sleeve D, .so that the crank-shaft revolves inside of it, and the sleeve D turns or vibrates on the outside of it. The rear end of the sleeve D has a flange, a, which iits under and behind a lip, a', on the tubular projection F, so as to keep the sleeve in place, and, at the same time, allow the sleeve with its liange E to vibrate freely on the said skein of the projection. Heretofore the practiceV has been to attach a chain, O, to a lug on the flange E, as close tothe sleeve D as possible, and connect the said chain with the pole T of the harvester,

and thereby give support to the said flange and the inner end of the cutting apparatus. But, by thus attaching the brace-chain, a strong draft or strain comes upon the sleeve D in such a manner as to produce a powerful drawing action on the lip aand flan ge a, thereby frequently causing the saidparts to break and always to rapidly wear aw ay. B y my present invention the iexible brace or brace-chain O is attached to the tubular projection F back of the line of the main axle and beneath it, the attachment being, by means of a hook, H, or its equivalent, bolted upon or cast with the tubular projection. The brace-chain thence extends forward through a loop or eye, p, on the iiange E near the sleeve D, as shown, and thence forward and upward to the pole T. The loop p may also be either cast upon or attached to the iiange E. Thus the strain on the sleeve D and its iange a, as well as on the hook or lip a', is relieved, and the support is transferred back to the frame portion supported by the main axle, and no part is liable to give way and none of the working parts are subjected to undue friction.

What I claim as my invention, and desire to seciue by Letters Patent, is-

The brace-chain O, attached to the frame or tubular projection F and to the pole T, and supporting the flange E of the sleeve D by means of the loop p, substantially as and for the purpose herein speciied. Y
