Letters Patent No. 109,269, dated November 15, 1870.V

IMPROVEMENT IN CQMBINED HARROWS AND SEDERS.

The Schedule'referred to in these Letters Patent and making part of the same.

I, Enna Srosnu, of Greencastle, in the county of Improved Harrowand Seeder Combined, of which the followingT is a specification.

The lirst part 'of my invention relates to the combination ot an adjustable endless apron or band of rubber or other elastic material, with one ofitwo pulleys or rollers, under each droppiiig-aperture in the bottom ot' a seed-hopper, the apron being stretched over a third thereof, the objectof this part of my invention being` to' facilitate the discharge and distribution of the seeds.

The second part of mylinventiou relates to an arran gement of spur-gearing, consisting of three equaltoothed wheels, meshing in train, and secured respectively upon the two parallel roller-shafts under the hopper and upon the axle of the machine, under one of them for the purpose of driving the roller-shafts and one .end to the rear bar from which the harrowis in part suspended, and so pivoted to the frame-workat from the ground will cause the inner end of the lever to bear upon `the axle, and to elevate the frame of the machine, and with it the toothed wheels upon its roller'- shafts, so that they will be disengaged from their connection with the toothed wheel on the axle, (this upward movement of the frame from the axle being permitted by means of an extended vertical slot in the bearing or journal-box of thc.axle,) the object of this part of nry'invention being to relieve the rollers andaprons of='the seeder from wear and teal-when the inachin'es not in operation.

In the accompanying` drawing- Figure 1 isa top or plan view of my improved ina-4 chine..

Figure 2, a rear elevation thereof.

Figure 3, au underneath lview of the bottom ofthe hopper, Sac., with all but one oi' the seeding-rollers removed.

Figure 4, a vertical section in line y y of tig. l, giving an end View of the hopper, and illustrating the attachment and operation of the lever, gearing .and nngearing' the toothed wheels on the axle anrLroller-` shafts.

Figure 5,' a vertical section in line s of iig. 2, giv. ing an v,elevation of the opposite end of the seed-hopper and ofthe devices for fmoving the agitators' or stirrers within the same, and. for conncctingthe wheel with the revolving axle ofthe machine.

A is a seed-hopper of usual form and construction, supported upon a frame, B, by means of, interposed' blocks, C O, at either end.

The frame B is constructed of the side-bars li'b, connected by atransverse bar, c, in front, to the center whereof a tongue or pole, D, is secured.

E is the axle of the machine, turning freely in suitable boxes, ce', secured to the under side of the bars b li', ofzthe frame B, 'under the blocks C O, supporting the hopper.

H H are wheels ot ordinary construction, carrying the ends of the axle E.

The journal-box e', at one end of the axle, is slotted vertically, so as to permita movement' of the bar Zi', of the frame, independent ofthe axle.

F F' are arms or levers pivoted to the rear ends of the bars b b of the frame, at a point on the outer face of each, in the rear of the axle.

These levers extend outward beyond the ends of the hars b b, and are connected by a transverse bar,

The inner end of the-lever F', pivoted to the bar b w w 'lol and central cross-bar, the cross-bar, in common with the side-bars, heilig properly armed with teeth.

lhisharrow W is swung beneath the seeder A, by means of short chains, t t, (connecting its cross-bar with the rear bar G,) and an extended pivoted link, u, connecting its front angle with the front bar c of the frame B, immediately in the rear of the tongue D.

The chains t t are so proportioned as that, when the bar G is elevated so as to be caught by a hook, s, ou t-he hopper, the harrow will be lifted entirely clearfrom the ground,;s01-as to be readily transported from eld to eld. By 'dropping 'the bar G the harrow is left free to dra-g upon the soil. Its transverse bar strikes in theV rear of the seed-apertures of thehopper, so that the seeds will be caught and distributed or buried by its teeth, the rear bars beingarmed with narrow shares in addition to the ordinary points, to facilitate the latter end.

K is a spur-wheel, securedto the axle inside ofthe block O.

` L L', (see fig.4,) are-two parallel shafts, made of anni dans L', gearing in to the toothed wheel onvL, will also gear p into the spur-wheel K on the axlell. Hence, when the' harrow is dropped to takehold ofthe ground, the vsrinr-gearing is complete, and the shafts L'L will revolve in unison with the axle, while the elevation of theharrow by the lifting ofthe bar G will, through the movement of its leverll", unship the .gearin g and laure the axle free-to turn independently ofthe roller-shafts LL.

M M ate rollers, secured in pairs, one, upon each shaft, under each droppingLapel-ture in the bottom of the hopper, along its'entire length.

M is a pulley of equal diameter with said rollers, revolving in a suitable bracket, f f, secured to theunder side of `a plate, 0," sliding in ways upon the under side of the hopper, in the rear of each pair of rollers.

N is an elastic band of rubber, passing over the pulley Mf and the roller 'M' nearest thereto. This band may be tightened or loosened by means ofthe sliding plate O, which isy secured by a set-screw, g', working through a 'slot in the plate as shown in iig. 3.

l) (see iig. 5) is'a disk, secured eccentrically on thc outer side of the'end of t-ho hopper A, in t'lieprojecting emLof the shaft K'.

Q (sce dotted lines, fig. 2,) is a rocking-shaft, extending longitudinally through the hopper, and setin motionby means of a' crank, q, upon its outer end, connected, -hy a link, i, to lthe eccentric 1. rocking-shaft Q is placed a yseries of arms or stirrers,

one over' each seeding aperture, wl1ichi'rom thero'cking rnoycmentof `the shaft, are iliade to ,swing back and forth in the hopper over said apertures, to agitate l the Train and revent it fromclonr inw as it )asses out.

b D D lhe wheels H H may bel fastened upon the Aaxle E, or-may'be leftfree to turn thereon. In the latter case I iix aV pawl, R, upon theinner end of the hub of the' wheel, (see iig. 5,) to engage a concentric ratchet, 7s, upon the axle, the teeth ot' the ratchet being so in.-

Upon this clined, and the pawl so adjusted with reference thereto, as that, when the machine is carried forward, the pawl will engage the ratchet and cause the axle to revolve with the wheel butin case of a reverse move ment,the wheel will turn upon the axle independently thereof. v

The dropping-apertures in the bottom ofthe hopper slides, in the usual manner. The employment of the horizontally-moving elastic bands N N, in combination with an opposite roller, M, under the seed-apertures, insures a more perfect andregular deliveryof the seeds than is attained by the ordinary devices.

and shares on its transverse and rear bars bury and cover the seeds dropped in front thereof.

By properly adjusting the seed-apertures iu the bottom of the hopper, the quantity of seed 'to be sown is perfectly controlled.

Although my machine is especially adapted for sowing'brozulcast, AI, nevertheless, can readily adapt it for sowing in drills, bysecuring thereto the ordinary drilltubes in proper position under the apron under each aperture.

I. claim as my inventionl. The combination of an elastic endless apron with rollers and pulleys under each dropping-aperture in the hopper of a seeding-machine, said apron heilig arranged and made to operate substantially as andv forA the `purpose herein set forth.

2. The combination of the lever l1" with the end of the axle E and with the frame bof a seeding-machine, substantiall y as and for the purpose herein set forth.
