IMPROVEMENT IN HARVESTER-DROPPERS.
Specification forming part of Letters Patent N o. 139,395, dated May 27, 1873; application iled Apri111, 1873.
To all whom 'it may concern:
Be it known that I, NILs JOHNSON, of Newburg, in the county of Fillmore, in the State of Minnesota, have invented a certain Improvement in Harvester-Droppers, of which the following is a specification:
This invention relates to that class of harvester-droppers which, consisting of a platform hinged in rear of the cutter-bar, are supported in a horizontal position While gathering a gavel of grain, and periodically dropped at the rear end to discharge such gavels, by meansof a lever which is connected to the platform and bears against the periphery of a revolving sectoral disk, which permits an inthe platform as stated. My improvement consists in a novel arrangement of the parts hereinafter more fully explained.
Figure l is a plan view of a harvester embodying my improvement. Figs. 2 and 3, which are drawn on a larger scale, illustrate my improved mechanism for operating the droppe The same letters of reference are used in all the figures in the designation of identical parts. The dropperplatform A, which may be constructed in any approved manner, is provided at each end, near its forward edge, with fixed journals, by means of which it is pivoted re- `spcctively to the main frame and the divider, `directly in rear of the cutter-bar. An arm, B,
fixed to the dropper at its inner side, projects underneath the side-beam O, and is connected by a link, D, to the arm e of a lever, E, fulof the lever to operate crumed on the beam C. the lever projects under and bears against the surface of the sectoral disk F. This disk has a sheave, G, fastened to it, and turns on an axis, g, carried on the main frame. lRotary motion is imparted to this disk from a pulleyr during every revolution of the sectoral disk,
the gap z' therein permits the other arm, e, of
the lever to descend and drop the rear end of the dropper.
I do not propose to claim broadly operatin g a dropper by means of a revolving cam or equivalent device, turning 011 an axis inde pendent of the reel, but confine myself to the special features and arrangement of parts hereinbefore described.
What I claim as my invention, and desire` to secure by Letters Patent, is-
The relative arrangement of the dropper A,
link D, lever E, and revolving sectoral disk F, turning on an independent axis, all the parts being combined and operating substantially as and for the purpose specified.
In testimony whereof I have name to this specification in the two subscribing witnesses.
NILS JOHNSON.
