Harvesters.
No. 142,903. Patenied September16,187-3..l
UNITED STATES PATENT OFFICE.
J OHN W. H. DOUBLER, OF WEST ALDEN, NEW YORK.
IMPRQVEMENT IN HARVESTERS.
Specification forming? part of Letters Patent No. 142,903, dated September 16, 1873; application filed September 12, 1873.
To all whom it may concern:
Be it known that I, JOHN W. H. DOUBLER, residing at West Alden, in the county ofErie and State of New York, have invented certain Improvements in Harvesters, of which the following is a specification:
The nature of my invention consists in the combination of certain parts of a harvester,as hereinafter more fully described and claimed.
Figure 1 is a plan View of a mowing-machine containing my improvement. Fig. 2 is a rear elevation. Fig. 3 is a side elevation.
The same letters of reference are employed in all the figures in the designation of like parts.
In the machine illustrated in the annexed drawings the cutter-bar is reciprocated by a mechanism consisting of a rotating helical disk, A, cross-head B, sliding on a guide-rod, O, and a pitman,-D, which is connected at one end to the cross-hea'd,.and at the other end to the heel of the cutter-bar E. The helical disk is, near its periphery, embraced by the antifrietion rollers b and b, which revolve on studs projecting from the side of the cross-head B. The guide-rod (J is secured to the lugs c and 0 upon the frame of the machine, the lugs being such a distance apart from each other as to allow, aside from the play of the crosshead, a certain length at each end of the rod for the reception of spiral springs F and F, whichencircle the rod, abutting with one end against the respective lugs c and c, and extending with the other end toward the crosshead. The length of the springs is so proportioned that the cross-head will compress them alternately as it approaches the end of its stroke in either direction. The cutter-bar is thus effectually cushioned, and the shocks and strains upon the driving mechanism very materially lessened 5 at the same time the power stored up in the springs is made available on the return strokes.
Other forms or kinds of springs than the spiral ones shown may be used, if preferred.
What I claim as my invention, and desire to secure by Letters Patent, is-- The combination of the helical plate A, cross-head B, guide-rod O, springs F F, pitman D, and cutter-bar E, substantially as specified.
In testimony whereof I have signed my name to the foregoing specification in the presence of two subscribing witnesses.
JOHN W. H. DOUBLER. Witnesses:
E. H. EWELL, M. G. ALGER.
