IM PROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 196, 15 8, dated October 23, 1877 application filed May 18, 1876.

To all whom it may concern:

Be it known that I, STEPHEN HULL, of Poughkeepsie, in the countyof Dutchess and State of New York, have invented certain new and useful Improvements in Harvesters, which improvements are fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure l isa plan view of my improved harvester. Fig. 2 is a front elevation and partial section, the traction driving-wheel being shown in section in order that the constructionof the same may be clearly seen. Fig. 3 is a side elevation of a portion of the draft-frame, the traction driving-wheel, its side pinion, and a plate having all the bearings for the sicklemotion formed upon it. Fig. 4 is a vertical central crosssection of the machine through the perpendicular rake and reel arm shaft;

Fig. 5 is a bottom view of the plate which has the bearings of the sickle-motion formed on it. Fig. 6 is a detailed view of a swinging plate to which intermediate and interchangeable gear-wheels for changingthe speed of the rake and reel apparatus are fastened. Fig. 7 is a detail section taken in the line a: a; of Fig. 1.

The nature of my invention consists in certain constructions, combinations, and arrangements of parts, as hereinafter described and specifically claimed, whereby an improved harv'ester is produced,as will be herein shown, which is of very simple construction.

To enable others skilled in the art to understand my invention, I will proceed to describe it.

In the accompanying drawings, A repre sents the driving-wheel, connected with the draft-frame by means of journal-bearings a. The said driving-wheel is cast in one piece, and its constituent parts are the hub A, the arms (0, the toothed annulus or inside gear A and an annular web, A which unites the annulus A and the arms a with thetread or rim A. The said web A begins at the inner end of the annulus A and thereby forms, with it and with the rim A an annular groove, a in which such soil, stones, and trash as occasionally gather upon the said rim and are lifted up by it are permitted to enter, so that, in falling down, they shall not enter between the teeth of the annulus and its pinion. At the other side of the web A a more shallow annular groove, a is formed by means of the rim A and an annular flange, m, of the web, to which the arms a are united. The arms a are, at the said point of union, curved outwardly, as seen at a in Fig. 2.

The described formation of the arms a and the flange 0 serves to prevent soil which is carried up on the corresponding side of the rim A from falling on the hub below, or on the pinion of the driving-wheel.

The shaft B of the driving-wheelpasses beyond its bearing a on the grain side, and is there provided with a pinion, I). The frame to which the said bearings are fastened consists of the bars 0 O and D D D The bars D D are parallel, and are supported by the bearings a of the driving-wheel. They are also in a higher level than the bar D which unites the grain ends of the bars 0 O, for which purpose the latter bars are bent down toward the level of the finger-bar E, as seen in Fig. 2. The intermediate bar D has aplate, F, attached below it, which has the journalbearings f f f of the sickleanotion attached to it. The pinion Gr of the said sickle-motion gears into the annulus A and, by means of a bevelgear wheel, G, on its shaft 9, at the other end of its journal-bearing f, transfers its motion to the bevel-gear wheel H on the shaft h, which is supported by the journalbearings f f and has at its other end the balance or crank wheel of the sickle-bar.

Motion for the operation of the rake and reel arms is obtained from the pinion b on the main shaft B. From there it is communicated to the pinions I and K, which latter is fastened to the shaft k. The wheel I revolves on astud, z, fastened to a plate, I, which is made to swing on the main shaft B, and is secured in its position by a bolt, z", and an upright stand, I forming a part of the journal-bearlll fl.

The stud z' is not moved 011 the plate I, as the central distance of the two wheels b and I, which are of different size, remains unchanged when the wheels are exchanged for the purpose of changing the speed of the combined rake and reel. In case of such an exchange the central distance between the wheel I on the stud and the wheel K is changed, and in order to secure the gearing condition of the said wheels the stud tmust be kept 'sitions. the bar D, and another, I, in the upright stand closerto or farther from the axis of the shaft of the wheel 'K, which is done by loosening the bolt i? and swinging the plate 1 toward or from the said axis. 7

By substituting for the smaller wheel K the larger wheel I, the speed of the combined rake and reel will be decreased, and vice versa by replacing the said wheels in their original po The shaft 70 has one bearing, is, on

L, which is fastened upon an intermediate platform, X. 'A wheel, K, at the other end of the shaft 70 communicates its motionto the crownavheel L upon the upright shaft'l in the stand L; To the top of the wheel L a number of stands, 3 are attached, to which the shoes M of the rake-arms M and; shoes N of the reelarin N are hinged or pivoted in alternate order. 'Above the crown-wheel L,

and below the rakehead cap (),a number of washers, Z arefitted on the shaft 0, which,

cap 0 on the shaft l. The rake-head cap 0 has a bearing-rim, 0, at V the grain side, which bears on the forked stem. m of the rake-arm' shoe M, and thereby keeps the rake-teeth m of the rake Ml down uponthe grain-platform E. p

r The reel-arm N is made adjustable 111 its reel-arm shoe N by means of a pivot-pin, a, a

concentric slot, n in the said shoe,-and a setscrew, n for fastening the arm in the desired position.

Q and p are guides for the rake and reel arms M and N. n and M are bearing projections provided on the shoes of the rake and reel arms.

The diameter or radius of the rake-arm guide Q is far less than the diameter or radius of the reel-arm guide The general form of these guides is the same as those in other harvesters having a combined reel and rake, and the difference between the operation of the guides Q and p, and other similar guides, is in the arrangement of the projections n and M the projection 42. moving clear of the guide Q and running upon the guide 12, and the projection M movingzclear of the guide 1) and running upon the guide Q. By these means the rake-arm is allowed to drop down close upon the platform and rake off the grain, and the reel-arm is held up above the platform and allowed to pass over the cut grain; and still both the rake and reel arms are elevated to a vertical position by the guide Q, and guided to their work in the most perfect manner.

The outer end of the reel-arm N projects over the grain-guard 0, so as to be of proper length, and this arm may be provided with short teeth of, for the purpose of combing the uncut grain or straightening and guiding the same to the cutters in a parallel position. The vertical elevation of the reelandrake arms, by means of the cam-guides Q, serves to avoid contact with the machinery and the driver,

and in their elevated position portions of their shoes N and M are caused to travel upon the inclined or helicoidal guide Q, which is, by means of legs or stands g,lfastened to the platform X. 7 V

' It will'be noticed that the guides p and Q, are of unequal'radii, and that, therefore, the bearing-points of the shoes of therakearms do not reach tothe guide 1) while the rake is V sweeping the grain from the platfornu By these means the eke-arms are allowedto drop down upon the platform for raking off the cut grain, and the reel-arms prevented from so dropping after they have reeled in the-grain to be cut. 7 V V V i p The detachableplatform X is fastened upon the extension of the grain-platform or its I frame 1%, as shown in Figs. 1, 2, and 7, so that it partakes of all the I movements and positions of the grain platform, and thereby insures a correct and undisturbedmotion of the rake and reel arms. 7 V V V c j V 1 For the purpose of elevatingand tilting the grain-platferm, 7 bar, the mainframe of "the grain-platform is fastened to the bar. I) of the wheel-frame, by

V a rookingbolt, 'r, with spherical end bearings,

and an adjusting-bolt, r, and the extreme end of the f HiIKIQ-GXtGIlSlOll R is suspendedby an adjustable bolt, W, to the bar 1). The fingen bar E, with its appurtenances, isfastened to the'bar Dat one end, and to the grain-divider I S at the other end, the same as the front end of the grain-platform.i V

The movement of the crown-wheel and the rake and reel arms may be stopped at a moments notice by means of one of the wellknown clutclrconnections, T, between the shaft 70 and the loose wheel K, as partly shown in Figs. 1 and 2.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination of the harvester-frame C O D D plate F, having journal-bearingsf f 1 f, and the shafts g and h, all substantially as and for the purpose described.

2. The pinions I, b, and K, of different sizes, and arranged to be adjusted and interchanged, as described, in combination with the main shaft B, plate I pivoted thereto, and the gearing and shafts of the revolving rake, all substantially in the manner and for the purpose described.

3. The combination of the shoes M M and N n of the rake and reel arms, and the camguides Q and p, of different radii with respect to the verticalrake-shaft, all substantially in the manner and for the purposes described.

Witness my hand, in this my application for a patent for improvement in harvesters, this 15th day of March, A. D. 1876.
