HENRY POOLE, OF BATTLEHILL, ASSIGNOR OF ONE-THIRD TO JOHN H. PRESCOTT, OF SALINA, KANSAS.

BROOlVl-CORN HARVESTER.

SPECIFICATION forming part of Letters Patent No. 434,070, dated August 1 2, 1890.

Application filed March 13, 1889.

To all whom t may concern.-

Be it known that I, HENRY POOLE, a citizen of the UnitedStates, residing at Battle Hill township, in the county of McPherson and State of Kansas, have invented certain new and useful Improvements in Broom-Corn Harvesters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as willr enable others skilled in the art to which it appertains to make and use the same.

My invention relates to machines for Aharvesting broom-corn; and it consists in the improved construction and arrangement or combination of parts of a harvesting-machine, in which is combined cutting, assorting, recutting, and seed stripping mechanisms for broom-corn, as will be hereinafter fully disclosed in the description, drawings, and claims.

In the accompanying drawings, forming a part of this specification, in which the same reference-numerals indicate the same parts7 Figure l represents a top plan view of the machine, the asserting and recutting table, and the recesses and openings therein being shown in dotted lines in order to disclose the mechanism beneath the same, the reel, its standard, and other parts being omitted; Fig. 2, a side elevation, partly in section, looking from the left side of the machine, and showing the seed-stripping mechanism and the gearing for operating the same, the end of the stripper-casing being omitted; Fig. 2, a detail view of the gearing for operating the seed-stripping mechanism; Fig. 3, an elevation of the rear end of the machine, the rear side or wall of the casing of the seed-stripper being omitted, other parts being in section and broken away; Fig. 3, a detail plan view of the vertically-movable box or sleeve on the reel-standard and of the bearing for the inner end of the reel-shaft; Fig. 3m, a section of one of the stationary and revolving knives or cutters; Figs. 4 and 4, a section and face view, respectively, of the racks and one of the pinions for raising and lowering the cutting and conveying mechanisms; Figs. 5 and 6, a face view and a sectional detail, respectively, of the hinged portions of the reel-standard; and

Serial No.303,083. (No model.)

sills or bed-timbers, with their bearings, rest upon said main axle and support and carry the entire main frame and all the gearing of the machine.

The two drive-wheels 2 are provided on their inner sides with cogged rims 4, which mesh with and drive the two pinions 5, which are secured upon the ends of the shaft 6, which is mounted in suitable bearing secured to the sills or .bed-timbers 3, and arranged parallel to and to the rear of said main axle, as shown in Figs. 1 and 2. pinions the power is applied for driving all parts of the machinery. The pinion 5 on the end of this shaft at the right side of the machine is provided on its inner face with a half-clutch 7, which is adapted to engage another halfclutch 8, as shown in Fig. l. A coiled spring 9 surrounds the shaft 6 and forces said half-clutch 8 against said halfclutch 7. This pinion 5 and the half-clutch 7 are adapted to revolve freely upon said shaft 6, while the oppositehalf-clutch 8 will revolve with and slide upon said shaft. These devices permit the drive-wheel on the right side of the machine to stand still and the other drive-wheel to revolve as the machine is turned. Near the center of the shaft 6 is also secured a large gear-wheel l0, which is provided on its right face with a half-clutch 11, which engages another half-clutch 12, which Through this shaft and its,`

is adapted to slide upon and revolve with IOO the last-named half-clutches and allow the drive-wheel on the left side of the machine to stand still and the other drive-wheel to revolve as the machine is turned, and also to allow the machine to be thrown into and out of gear. The large gear-wheel meshes with a pinion upon a horizontal shaft 16, which is journaled upon the center and right sills or bed-timbers 3 and arranged parallel with and to the rear of said shaft 6, as shown in Figs. 1, 2, and 3. This shaft 16 is provided on its end at the right side ofy the machine with a bevel-pinion 17, which meshes with another bevellpinion 18 upon the lower end of a vertical shaft19, which is journaled in a bracket 20 at the rear of the right side of the machine, as shown in Fig. 3.

For the purpose of raising and lowering the frame or table which carries the harvesting or cutting and conveying mechanisms, two vertical posts 21 and 22, as shown in crosssection in Fig. 1 and in side, sectional, and front elevation in Figs. 3, 4, and 4, are attached to the side of the machine, respectively, near the front and rear ends of the sill or bed-timber on the right side thereof. Flat plates 23 are secured to the faces of said vertical posts by bolts 24 and have their edges projecting beyond the sides of said posts, so as to form T-shaped ways. Two iiat plates 25, which form the vertical parts of two triangularly-shaped brackets 26, bear loosely against the faces of the iiat plates 23 and are rigidly secured to slidable flanged boxes or clamps 27 at their upper and lower ends.Y These flanged boxes or clamps fit and slide upon said T-shaped ways and have bolted to them the rods or braces 26', which form the rear parts or sides of the triangularly-shaped brackets 26.

Secured to the outer faces of the vertical plates 25 are the rack-bars 28, which, being rigidly fastened to the slidable boxes 27, are movable up and down by a shaft 29, which is arranged on the right side of the machine and provided with pinions 30, which mesh with said rack-bars, as shown more plainly in Figs. 1 and 2. This shaft is journaled in suitable bearings 31, and upon its forward end is pro-v vided With a worm-wheel- 32, which is operated by a worm 33 upon the lower end of an oblique shaft 34, as shown in Figs. 2 and 3. The upper end of this shaft has a hand-wheel 35, by means of which the driver can revolve said shaft and its worm `33, which will turn the shaft 29, its worm-pinion 32, and pinions 30, and thus raise or lower the plates 25, the rack-bars 28, and the brackets 26 by said pinions 30 meshing with said rack-bars.

The frame or table 36, which carries the cutting and the conveying mechanisms, is support-ed upon the horizontal extension or extensions 26 of the brackets 26, as shown in Fig. 3;also, the shafts 37 and 38 of the rollers 39, over which travels the endless conveying-apron 40, are journaled at their ends Vin vthe front and rear sides of said frame or ta- -asshown plainly in Fig. 7.

ble, as shown in Figs. 1 and 3. The rear end of the inner roller-shaft 37 has a bevel-pinion 44, which meshes with a similar pinion 45, which is supported upon a bracket 46 on said frame or table, and is splined or adapted to slide upon and revolve with the vertical shaft 19, as shown in Figs. 1, 2, and 3. As the shaft 37 and pinions 44 and 45 are mounted upon said table or frame, it will beobvious that the cutting mechanism, hereinafter described, will be operated simultaneously with the endless conyeying-apron 40, which will be continuously moved or carried over its rollers by the gearing described at whatever height the said table or frame carrying the cutting mechanism and conveying-apron may be adj usted.

The cutting mechanism consists of the cntter or sickle bar 47, which is arranged to reciprocate with respect to the 1in ger-bar 48, which is secured upon the forward end of the table or frame 36. To the inner end of said cutter or sickle bar is secured a two-part yoke 49, which is provided with a vertical slot 50 and with a projection 51, which is itted to slide in a bearing 52, secured upon said table or frame, and serves to guide and support said inner end of the cutter or sickle bar. The forward end of the shaft 37 is provided with a disk 53,having awrist or crank pin 54, which projects within the vertical slot 50 and operates to reciprocate said cutter or sickle bar,

Suitable forwardly-projecting guides 48 are secured to the ends of the iinger-bar 48 for the purpose of directing the corn toward the cutter-bar.

A receptacle or trough 51 is suitably secured at the inner side of the table or frame 36 and serves to receive the heads or brushes of the corn after they have been severed by the cutter-bar and carried inward bythe endless apron over the inner apron-roller 39.

A plate 52 is secured to the inner face of the upper portion of the forward post 2l and is provided with a disk 53 at its upper end; also, a similar plate 54 is secured to the lower portion of the reel-standard 55 and formed at its lower end with a correspondingly-shaped disk 56, as shown in Figs. 3 and 6. These disks are pivotally secured together by a bolt or pintle 57. The disk 53 of the plate 52 on the vertical post 21 is formed with a single hole 58, while the disk 56 of the plate 54 on the reel-standard 55 is formed with a number of holes 59, which are arranged in a circle or segment concentric with said bolt or pintle and register with said single hole 58. A latch or dog projects through said hole 58 and is adapted to engage any one of the holes 59 when brought to register therewith; also, said latch or dog is pivoted to one end of a hand-lever 61, which is fulcrumed upon the face of the disk 53` with a spring 62 bearing outward against its other end. By these adjustable disks, which are pivotally bolted together and formed with the holes 58 and 59 and provided with the spring-actuated lever 61, having the dog or latch 60, a hinge TCO IIO

is formed for the reel-standard, which permits the same to be adjusted or tilted forward and backward and firmly' held in such positions.

Upon the upper portion of the reel-standard 55 is fitted a box or sleeve 63, which is adapted to be slid thereon, and is provided with a transverse bearing 64 for supporting the inner end of the shaft 65 of the reel 66. The outer portion of this reel-shaft is supported in a bearing 67, which is held out from the box or sleeve 63 by a brace-rod 68, which is secured to said bearing and box or sleeve, and said bearing is further supported by an oblique brace 69, which is secured at its lower end to a box or clamp 70, which is also adapted to be slid upon said reel-standard and is connected to the upper box or sleeve 63 by means of a bar or plate 71. A rod 72, which is screw-threaded along its middle portion, is secured at its upper end to the box or sleeve 63 and is arranged parallel to said reel-standard. The middle portion of thisv rod passes through a hole in a bracket 73 on the disk 56 of the plate 54. A hand-wheel 7-1, having a screw-threaded central bore, is adapted to be turned upon said shaft and bear against the upper side of said bracket 73. It is thus obvious that the box 63, bearing 64, reel-shaft 65, and the reel 66 can be raised and lowered by the screwthreaded rod 72 and the hand-wheel 7l by revolving the latter. (See Fig. 3.)

From the upper box or sleeve 63 project upward and downward two brackets 75, having studs or stub-axles 76, upon which are mounted two sprocket-wheels 7 7. A sprocketwheel 7S is also secured upon the inner end of the reel-shaft 65 between said sprocketwheels 77; also, a sprocket-wheel 79 is journaled upon the upper end of the reel-st andard; also, two sprocket-wheels 80 and 81 are secured to a sleeve 82, journaled upon the pivotal bolt or pintle 57 of the adjustable disks 53 and 56 or hinge of said standard. A sprocket-chain 83 passes over the upper wheel 79, under the inner wheel 80 on the sleeve 82, inside of the two wheels 77, and outside of the wheel 78 on thereel-shaft, and thus when the wheel 81 is revolved, which is secured to the inner wheel 80, said chain 83 will revolve the reel-shaft and reel. (See Figs. 2 and 3.) Under this arrangement of the sprocket-wheels the reel and its shaft may be raised or lowered without requiring` any adjustment of said wheels or the sprocketchain 83, and also the reel-standard may be tilted or adj usted forward or backward without interfering with the driving of the reel.

A sprocket-chain 84 passes over the outer sprocket-wheel 81 and under one 85 of two sprocket-wheels 85 and 8G, which are journaled upon a short shaft 86', secured at one end to the right sill lor bed-timber 3 and at the other end to a suitable support, as shown in Figs. 2 and 3. A chain 87 passes around the other sprocket-wheel 86 and around another sprocket-wheel 88, mounted upon the shaft 6, as shown in Figs. 1 and 2, from' which the power is derived for revolving the reel through the l1ereinbefore-described gearing. A bevelpinion 89, Figs. 1, 2, and 3, is secured upon the shaft 6 and meshes with another bevelpinion 90 upon a short shaft 91, which is suitably journaled in the rear left side of the main frame and provided with a sprocketwheel 92, as more plainly shown in Figs. 1 and 2. A chain 93, as shown in Figs. 2 and 3, passes under said sprocket-Wheel 92 and over a large sprocket-wheel 94, which is secured to a horizontal shaft 95, which is journaled in bearings 96, attached to the' main frame, as shown in Fig. 2. A smaller sprocket-wheel 97 is also secured to said shaft, and around the same is passed a sprocket-chain 98, which also passes over a sprocket-wheel 99, under an adjustable idlerpulley 100, over and around a pulley or sprocket-wheel 101, and back to said sprocket-wheel 97, as shown in Fig. 3. The sprocket-Wheel 99 is secured upon a shaft 102, which extends longitudinally of, and is journaled close beneath,the asserting and recutting table 103, and is providedat its rear end with a revolving knife or cutter 104E and at its forward end with a similar knife or cutter 105, as shown in Figs. 1 and 2; also, the sprocket-wheel 101,'which is driven by the chain 98, is secured upon the forward end of a longitudinally-extending shaft 106, which is also journaled just beneath the assorting and recutting table 103 and provided IOO with a revolving knife or cutter 107 at its rear l end, as shown in Figs. 1 and 3. This assorting and recutting table, as shown mbre fully in Fig. 1, is formed with three recesses 108, at the forward ends of which revolve the knives or cutters for severing the heads or brushes from the short butts or pieces of the cut cornstalks 5 also, a much larger recess 108 is formed in the right side of said table between the trough 51 and the center of themachine, and within said recess is located an operator, who stands upon a platform 109', which is suitably secured beneath said recess, and who takes the short cut pieces of stalks from said trough and places the same before the other operators, who are located in circular or other suitably-shaped openings 109 adjacent to said recesses 108, who stand upon platforms 110, which are also suitably secured beneath Said openings, who assort said short pieces of cut cornstalks upon the table, and who hold the heads of the same while the butts are cut therefrom by the respective sets of revolving and stationary knives or cutters.

The revolving knives or cutters, as shown in Fig. 3, consist of two rectangularly-shaped blades 111, which are secured upon opposite sides of their shafts and 4have their cuttingedges on the inner sides of the angles. The

IIO

shearing lor drawing cut. (See Fig. 3M.) A feed-wheel 113, as shown in Figs. 2 and 3, is secured upon the shaft 95 and is provided with a grooved or recessed periphery and radiating pairs of spikes or `teeth 114. A rope or cable 115 passes under said feed-wheel within the groove in its periphery and between the pairs of spikes or teeth thereon, thence over a pulley 11G, thence under a pulley 117 below, thence under a guide-pulley 118, which is secured in a tension-regulating spring-support 119, thence over a pulley 120, and back under the feed-wheel, both of said pulleys 11G and 120 being journaled above the shaft 95 and close to the periphery of said feed-wheel. An inclined feed-board 121 is arranged beneath an opening 121', formed in the top of the casing of the seed-stripping mechanism, as shown in Fig. 3, and through which the first operator feeds the brushes or heads of the corn after they have been returned to him by the other operators, who have assorted and attended to the cutting of said brushes from the short butts or stalks. When introduced into said opening, the brushes orheads pass down said inclined feedboard, over the pulley 120, and onto the periphery of i said feed-wheel, where they are clamped by the rope or cable in the spaces between the pairs of spikes or teeth. A pulley 122 is journaled slightly above and at one side of the pulley 116, and around the same passes a belt 123, which thence passes over said pulley 11(3, under said rope or cable, and around the feed-wheel in the grooved or recessed periphery thereof. The brushes or heads of the corn are thus held between said belt and rope or cable, carried lover the pulley116, and discharged from the machineinto a self-binding attachment or other device, which will form them into gavels. The feedwheel carries the brushes or heads by their butt-ends, so as to present their seed-laden ends to two spiked or toothed stripping-rollers 124, which are placed within a suitable casing and transversely j ournaled in the main frame. They are horizontally arranged one above the other, with a space between them, which is opposite the points of the spikes or teeth of the feed-wheel. The shafts of these seed-stripping rollers are provided with interineshing gear-wheels 125,the shaft of the lower roller being also provided with a small pinion 126, which is driven by a gear-wheel 127, which is secured upon a short counter-shaft 127', as shown in Figs-1 and 2; also, upon this counter-shaft near said gear-wheel is secured a small cog-wheel 12S, which receives motion from the intermeshing large gearwheel 10 on the shaft 6. Thus the seed-stripping rollers are revolved from the same shaft G that transmits the power received from'the main axle 1 and the drive-wheels 2 to all other operative parts of the machine.

An upright 129 is suitably secured to the main frame at the front end of the machine `and is provided with the drivers seat 130 upon its upperend, as shown in Figs. 2 and 3. "Within convenient reach of the driver upon this seat is arranged a lever 131, which is rigidly secured at its lower vend to a rockshaft 132, which is suitably journaled upon the forward end of the main frame, as shown in Fig. 2; also, an arm 133 is rigidly secured to and projects forward from said rock-shaft and has a link 134 secured to its forward end, which is secured at its lower end to a cross-bar 135 upon the draft-poles or shafts 136 of the machine. The hand-lever 131 may be held in its adjusted positions byaratehetbar or other ordinary stopping device; also, the inner ends of the poles or shafts may be secured to the forward portion of the main frame in any suitably desired manner. With these parts thus constructed and arranged, it will be obvious that when the driver moves the lever 131 backward or forward the front end of the machine will be raised or lowered, thus causing the entire main frame, which is pivoted upon the main axle 1, to assume a substantially.- horizontal position, whether the machine is traveling and working over an upwardly or downwardly inclined surface.

In operation the machine is moved forward, with the sickle or cutter bar extending across the row or rows of corn and with the reel and the frame carrying said cutter-bar and the endless conveying-apron adjusted to the height of the corn to be cut. Then said cutter-bar, assisted by the finger-bar and the guides, cuts off the heads or brushes from the stalks of corn as they are pressed against it by the reel. brushes are received upon the endless con-- veying-apron,'carried inward thereby, and delivered into the receiver or trough. Then they are distributed and assorted by the operators and recut by the revolving knives, as hereinbefore described. Then they are roturned to the first operator, 4who delivers them, in their assorted and trimmed condition, through the opening in the table and upon the inclined feed-board, down which they pass to the feed-wheel, which carries and holds them to the stripping-rollers, by which the seed is thoroughly stripped therefrom, and then they are discharged from the machine into any suitable self-binding or other mechanism, (not shown,) which will form them into gavels or bundles. No claim is herein made for the improvements in the details of the seed-stripping mechanism, as substantially the same construction and combinations of parts form the subject-matter of an application for Letters Patent filed by me June 15, 1888, Serial No. 277,279, my present claims, which include said seed-stripping mechanism, relating to such combinations as are incident to the connection and use thereof in the same machine and as operated by the same source of power as the cutting, conveying, and recutting mechanisms, as hereinbefore specified.
