UNITED STATES WILLIAM ZIMMERMAN, OF OSKALOOSA, IOWA'.

IMPROVEMENT IN HARVESTERS.

Specication forming part of Letters Patent No. 55,758, dated June 19, 1866.

To all 'whom t may concern:

Be it known that I, VILLIAM ZIMMERMAN, of Oskaloosa, in the county ot Mahaska and State of Iowa, have invented a new and Improved Gavel-Discharging Device for Harvesters; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the saine, reference being had to the accoinl'ianying drawings, iorming part of this specification, in which- Figure lis au end view ot my invention; Fig. 2, a side sectional view of the same, taken in the line a: 10,Fig. 1.

Similar letters of reference indicate corresponding part-s. i

This invention relates to a new and improved gavel-dischargin g device for harvesters, whereby gavels of greater or less size may be discharged as desired, and the device made to operate with certainty and in a perfect manner.

The invention is designed to operatein connection with an endless apron-a means used on some harvesters for discharging the cnt grain from the machine. A

A represents a framing which is attached to one end of the platform of a harvester, and having a roller, a, placed in it, over which the endless apron works and conveys the out grain to the device. (See Fig. 2.)

ln the framing A there is hung or suspended a iiap or door, B, having arod, b, projecting from it, on which a counter-poise, O, is fitted. This counterpoise should be adjustable, and it may be made like a nut, to work upon ascrewthread cut on rod b. This eounterpoise is designed to keep the end of the Hap or door B in contact with a plate, c, in the framing A, as will be fully understood by referring to Fig. 2.

The outer end of the rod b has a cord, el, attached to it, and this cord passes over a pulley, e, in a bar,f, in the framing A, and is couliected to a rake, D, having an arm, g, at each end of it, said armsbeingpivotedin the framing A, as shown at It h.

By this arrangement it will be seen that when the tlap or door B falls the rake D will descend and take its place, and when the tlap or door rises the rake D will also rise.

The endless apron conveys the cut grain to the device and deposits it upon the `iiap or door B, which retains it until the gravity ot' the grain will overcome that of the counterpoise O, when the Hap or door B will fall or drop and discharge the gavel, the flap or door immediately rising after the discharge ot' the gavel.

As the Hap or door drops the rake D also drops, and retains the cut grain delivered by the apron until the flap or door rises, when the rake also rises out et' the way.

The size of the gavels may be regulated by adjusting the coun terpoise O. The farther the latter is turned out on the rod b the greater will he the weight required to force down the Hap or door B, and consequently the larger will be the gavel.

I would remark that I employ a catch, E, at the outer part of the framing A, to enga-ge with the outer end of the rod d of the flap or door. This catch serves to hold the tlap-door until a sut'cient quantity ot' cut grain is upon it, and then releases the iiap or door suddenly, the rod (l disengagin g itseltl from the catch.

The device may be constructed and applied at a small cost, and usedon any reaper to which an endless carrying-belt may be applied.

Having thus described my invention,l claim as new and desire to secure by Letters Patent- The combination of the door B, screw-rod l), counterpoise O, spring-catch E, cord d, har f, rake D, and pivoted arm g, arranged relatively to each other, and with the endless carrying-aliron roller a, and operating in the manner and for the purpose herein specified.

WILLIAM ZIMMERMAN.
