HARVEY & BECKER.,
[i Thrasher. l l No. 41.003. Patented Dec. 22, 1863.
UNITED STATES THOMAS HARVEY AND NICHOLAS uvieaoviiivu-zwirv` J. BECKER, OF AMSTERDAM, N. Y.
IN TH FLASH ERS.
Specification forming part of Letters Patent No. 41,003, dated Dccclnber 22, 1863.
To all zrhom it may concern Be it known that we, THOMAS HARVEY and NioHoLAs J. BECKER, ot' Amsterdam, in the county of Montgomery and State of New York, have invented a new and Improved Attachment to Thrashers and Cleaners for Saving Grain, which we denominate a grain-gatherer; and we do hereby declare that the following is aiull and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. Figure l is a side elevation of our invention and Fig. 2 is a vertical longitu iinal section.
Like letters refer to corresponding parts in both figures.
The nature of our invention consists in applying au oscillating motion as a propelling power to the fan-shoe B by means ofa double cam, b, formed on the end of the fan-shaft and on the inside ofthe drive wheel or pulley.
This double cam b is attached to both sides of the cleaner, in order to produce a uniform motion ofthe fan-shoe, and is clearly deline ated in Fig. l, against which double cam on the fan-shaft a pulley or wheel, c, rests and turns. Arm k is pivoted to the upright post ot' the mill at 'i by a bolt, which acts as an axle. The other end or prong of arm L is pivoted or hinged by a bolt ruiming through the center of pulley c, on which the arm turns. That point ofthe arm at n contains a slot or groove, which receives the end of the rod e. Around this rod e we wind a spiral spring, c.
other or farther end of the rode is pivoted to the fan-shoe B at d. When the mill is in mo` tion, as the double cam b turns halt' around, the eccentric, pressing` against the pulley c, crowds back the arm k (which turns at t' and ln.) against the rod e, and thus compresses the cam, being on each side of the mill, act together, giving a regular and uniform vibra tory motion to the fan-sh0e B.
Our invention of usinga double cam on the fan-shaft and the mode of connecting the fan-shaft A with the fan-shoe and separatorshoe a will produce by one revolution of the fan-shaft two -n-lotions ot' the fan-shoe, while in the same revolution the separator-shoe makes but one motion.
What we claim as our invention, and desire to secure by Letters Patent, is-
The double cam b', in combination with arm k, rod e, and spring c', when constructed and operating in the manner and for the purpose herein set forth.
THOMAS HARVEY. N. J. BECKER. Witnesses G. P. WINEGAR,
The end of the rod e is pivoted at n. Thei D. C. VAN ALLEN.
