IMPROVEMENT IN HARVESTER-DROPPERS.

Specification forming part of Letters Patent No. 12,215, dated January 9, 1855;

' June 1, 1869.

Reissue No. 3,118,5dated DIVISION. No. 2.

To all 'whom it may concern:

Beit known that thelate JOHN E. NEwcoMB, of Whitehall, inthe county of Washington and State of New York, did invent certain new and useful Improvements in Mowing and Reaping Machines, of which the following is a full, clear, and exact description of that part ofthe invention or improvements which form the subject-matter of this division of reissue, reference being had to the accompanying drawings, forming-a part of this specification, in which- Figure 1 represents a plan or top view ofthe machine, the seat and tongue being shown broken oli". Fig. 2 represents a side view. Fig. 3 represents a. section on line A B,Fig. l; and Fig. 4 represents a section on line O D, Fig. 1.

To enable those skilled in the art to which the said NEWCOMBS improvements relate to lnake and use that part of the said NEWGOMBS invention or improvements which form the subject-matter of this division of reissue, I will proceed to describe it more in detail.

The nature of these last-named improvements consists, irst, in the combination, with the lingerbeam of a reaping-machine, of a dropping platform with mechanism for operating the same, whereby the driver from his seat on the machine can release said platform, by the simple action of his foot, so that it may drop down toward the ground at intervals to discharge the cut 4grain in gavels upon the ground; second, in supporting a dropping platform upon journals or pivots supported' by the outer and inner shoes of a reaping-machine, as hereinafter explained; third, inthe combination, with a dropping platform the journals of which are supported by the inner and outer shoes, of a crank or arm for operating the same, as hereinafter explained fourth, in the combination, with the crank or arin by which the dropping platform is operated, of a. shield or guard, as hereinafter explained; fifth, in the combination, with the platform-operating crank, arranged as hereinalter described, of an elevating, holding, and depressingrod or bar arranged parallel, or nearly so, to the line of motion of the machine, as and for the purposes hereinafter explained; sixth, in the combination, with the operatingcrank, which is combined with theinner journal of a dropping platform, as hereinafter described,ofaholdiogrod for retaining said platform in an elevated position until a sufficient quantity ofcut stalks of grain has been deposited upon the platform to form a gavel; seventh, in the combination, with the rod or arm which holds the rear of the platform in an elevated position, of a stop on the frame of the machine for retaining the operating-rod, for the time being, in a xed position, as hereinafter explained; eighth, in the combination, in'a reaping-machine, of-mechanism for automatically elevating the dropping platform, with mechanism for retaining said platform in an elevated position until released by the action of the drivers foot; ninth,in the combination, in a reaping-machine provided with a dropping platform, of a foot device so arranged and combined with the devices or parts which work the platform that they can be thrown in to gear at pleasure by the foot of the driver, for purposes hereinafter set forth; tenth, rin the combination, in a reaping-machine, with a fingerbeam arranged so that it can rise and fall to conform to the inequalities of the ground over which it is drawn, cfa dropping platform, with devices or mechanisms for operating the same, whereby the platform can, by means of mechanism thrown into action by the drivers foot, be retained in an elevated position or allowed to drop to discharge the gavel at the pleasure of the-driver; eleventh, in certain peculiar devices for operating a dropping platform in reaping-machines, as will be hereinafter explained; twelfth, in the combination, with the linger-beam of a reaping-machine, of an adjustable or extensible platform, as hereinafter explained; thirteenth, in a dropping platform for supporting thecut stalks of grain in a reaping-machine, made in longitudinal sections, one section of which can be moved to reduce the width of the platform, for the purposes hereinafter explained.

1n the' drawings, A is the platform, which is com posed in this instance of two parts, B and O. The front part, B, is secured to and supported by a shaft, D, which is arranged parallel with and back of theiinger-beam, and having its journals a a supported and fitted to turn freely in bearings supported by the shoes E F of the linger-beam. (See full and dotted lines in Fig. 1.) In this instance the ends G Gr of the part B are turned under to form flanges or ways b b for receiving and supporting the i ends H Hof the part C, which can be moved in or out under the part B, to widen or narrow the platform A to adapt'it for supporting stalks of grain of different lengths, it being necessary in that class of machines which discharge the stalks of cnt grain in gevels upon the ground from the rear side of the platform, by a drop or inclining motion of the rear thereof, as indicated in red lines, Fig. '3, that the platform should-be just wide enough to support the cut stalks in such a manner that the stubble will penetrate between the heads of the stalks as soon, at least, as the rear of the platform drops or inclines down to its lowesteX- tent. If the platform is too wide the heads of the grain will not extend over the rear side thereof sufficiently to be caught by the stubble when the platform drops or inclines back, and

lconsequently the gavel will be imperfectlydischarged, apart of the stalks remaining on the rear side of the platform until the latter isA raised, when they are thrown or drawn off in an irregular manner, while if the platform is too narrow the heads of the stalks, especially the heaviest ones, will hangover and be drawn oft' in a straggling manner before a sufficient amount collects or accumulates upon the platform to form a gavel. lt is therefore absolutely necessary and essential that the platform should be so constructed in this class of reaping-machines thatit can beadjusted to give proper support to the stalks, whether long or short, and at the same time admit ofthe stubble penetrating between that portion of the stalks of cut grain which projects over the rear edge of the platform as soon as the platform falls. The said NEWGOMB devised and has shown one good way ot' accomplishing this importantresult-viz., by making the platform extensible in the manner above described. If the stalks of the grain are long the part C may be drawn out, as shown in blue lines, Fig. 3,

or vice versa, and retained in place in its ad` justed position by the ordinary devices ofguides or ways and set-screws. l

. For the purpose of elevating and depressing the rear of the platform to discharge the grain at intervals to form gavels suitable for binding, an arm or crank, I, in this instance is fastened to the inner end ofthe shaft or platform-support D, and to the outer or upper end of this arm is hinged one end of a rod or bar, J, arranged parallel, or nearly so, with the line of motionof the machine. The rear end of rod J passes through an inclined slot, 0, in the projection d on the Linder side of the horizontal projection e on the foot spring-piece K, the rear end of the latter being fastened to the top of one of the side pieces of the main frame L, which is supported by the axle M, upon the end of which are the supportingw heels N N', the latter being fastened to the shaft or axle M in this instance, and is the driving-wheel. The forward end of the foot spring-piece is arranged so thatit can be con# veniently operated by the dr'vers foot as he sits on the seat O, which is sustained at a proper height above the main frame by means of standards P. fastened to the side pieces of said frame. The end of rod or bar J Works under a guide or loop, f, which is so made as to admit' of a lateral as wellas alongitudinal motion of said rod. The form of the guide or n loop f is indicated by full and dotted lines, Fig. 4. y Projection d works through an opening or slot cut or formed in the stand g, fastened to the side of the main frame. Loop fmay be supported on the stand g. Upon the main axle M is secured a cam, Q. The face of the cam revolvesjust back ofthe outer part of the oblique slot o in the downward projection d. (See Fig. 4.) A stop or check piece, m, is fastened to the side of the main frame, the front of the stop being flush with the face of the cam when the latter is in the position shown in Fig. 2.

The operation of raising and 'dropping the platform B to support the cut grain and discharge the same at intervals in gavels in snitv able form for binding is as follows: Assuming the parts to be in the relative positions shown in Fig. 2, with a sufficient quantity of cut grain upon the platform to form a gavel, the driver presses down the spring-piece K with his foot, thereby forcing down the projection d, which moves the end of rod J from the face of stop-piece m to the face of eam.Q, and as soon as the point n of the cam has passed the end of the rod the latter slides back into the depression o and the platform falls by its own weight, being accelerated by the weight of the accumulated grain thereon, and the grain isdischarged upon the ground in suitable form for binding. As soon as the gavel has been deposited the driver removes his foot from spring-piece K, and rod J, being forced forward by cam Q, crank or arm I, and platform B are moved back into the positions shown in dark lines, Fig. 3, and the action ot the slotted piece d upon the end of rod J, as the former is raised by the foot spring-piece K, forces it back in front of checkpiece m,

where it is retained until engaged again by the driver, as before explained.

It will thus be seen that the hinged or dropping platform is placed completely under the control of the driver, who can cause the platform to drop at pleasure. portant, since in some fields of grain, and in different parts of the same eld, it requires a greater surface to be cut than in other places, to secure a sufficient quantity of grain to form the desired size of gavel, and if the platform dropped to discharge the gavel at regular intervals the gavels would be irregular and not of uniform size.

To 'prevent the stalks of cnt grain from falling on or winding in about the platform operating crank or arm l and clogging the same, a guard or shield, R, is arranged to protect said arm, as indicated in the drawings. The

shieldRis in this instance fastened at its front end to the side of the frame forward of the arm I, and extends out and back, so as to fully protect thefront of thearmlbyguiding thestalks' in upon the platform, thus insuring afree and open space between the inner end ofthe hinged platform and the side of the inner shoe and main frame for the proper play of the crank or arm I and rod J'.

From the foregoing description it will be seen that the said NEWooMBs improvements are calculated to overcome and obviatc the objections which existed to the use of droppers as constructed prior to his invention.

If the driver had to hold the entire weight of the platform and the grain thereon Without the aid of a stop or check piece on -the frame of the machine, it would b laborious work, whereasby the use of a stop or check piece he is greatly relieved, so much so that a mere boy capable of driving the team can operate thedroppingattachmentwithoutunduefatigue or labor, thus rendering the machine still more valuable in an economic point of view.

A divider-board, W, is attached to the outer shoe, F, to aid in separating the cnt from the uncut grain. i

As the other parts of the NEWGOMB reapingmachine and mower are fully described in 'another division of reissue, of even date herewith, no further description is here deemed necessary.
