Description

UNrfrnn STAfrEs PATENT @Enron Lucius nvANs7 on FAYETTEVILLE, New Yoan.
IMPROVEMENT IN STRAW-CUTTERS.
Specification forming part of Letters Patent No. 125,555, dated April 9, 1872.
Specification describing certain Improvements in Straw-Cutters, invented by LUCIUS EVANS, of Fayetteville, in the county of Onondaga and State of New York.
rlhis invention, relating to that class of straw-cutters which combine in their construction two reciprocating knives and a pair of intermittingly-rotated feed-rollers, has for its obj ect to simplify and improve the mechanism for operating the knives or cutters and feedrollers; and to this end it consists in the combination, with the knives and the feed-rollers, of a :Hy-wheel on the driving-shaft with a projecting stud on its face and a pinion on the overhung end of the journal of the unyieldin g feed-roller, these parts being so arr. nged with reference to one another that the stud shall turn this feed-roller the proper distance at each separation of the knives to advance the straw or other fodder to be cut.
Figure l is a 'longitudinal vertical section on the line x w of Fig. 2 of my improved strawcritter. Fig. 2 is a front elevation, partly in section. Fig. 3 is a section on line y y of Fig. 2.
The same letters of reference are used in all the figures in the designation of identical parts.
The operative parts of the machine are mounted upon the forward end of a suitable frame-work, A, which also carries the box or trough B, through which the fodder is advanced to the feed-rollers C and C. The lower feed-roller C turns in unyielding bearings, but the journals of the upper one, C', have their bearings in' vertically-yielding boxes D, which are pressed downward by springs D in the ordinary manner. At one end the feed-rollers are geared together by pinions c and c with long cogs, so as to allow them to separate for a considerable distance without causing a disengagement of the pinions. The cutter-knives E and E', which are made of the angular form shown, so that they will act with a shearing cut, are fastened to sashes F and F', which slide in suitable guides on the frame-work. The sashes are connected by pit-men f and f to the respective cranks of the countershaft G, which is revolved by the drivin g-shaft H through the intermediate gear wheels H and G'. rIhe driving-shaft is located just beneath the lower feed-roller, and carries the fly-wheel I, to which is fastened the projecting stud I at a suitable distance from its axis to, strike at each revolution of the flywheel a cog of the pinion K on the overhung end of the journal of the unyielding feed-roller G. This stud is so arranged with reference to the cranks of the shaft Gr that it will operate the feed-rollers during the separation of the cutter-knives.
What I claim as my invention, and desire to secure by Letters Patent, is
The combination of the reciprocating cutterknives E and E', stud I on the ily-wheel I, pinion K on the journal of the unyielding feedrollers, and the feed-rollers C and C', all arranged, in relation to one another, substantially as specified.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
g LUCIUS EVANS.
