SEEECIEECATION forming part 0f Letters Patent No. 339,988, dated April 13, 1886.
Application tiled May 18. 18H3. Serial No. 95,342.
To all whom it may concern.-
Be it known that I, GEORGE G. HUNT, a citizen of the United States, residing at Bristol Station, in the county of Kendall and State ot Illinois, have invented certain new and useful Improvements in Grain-Binders, which are fully set forth in the following specification, reference being had to the accompanying drawings, in which--- Figure 1 represents a front elevation of a portion of a harvester with my improved grainbinder applied; Fig. Z, a detail elevation ofthe trip mechanism on an enlarged scale; Fig. 3, an elevation of the harvester, on the stubble side thereof, showing the binder on the same scale as Fig. 1; Fig. 4, a detail section taken on the line z z in Fig. 3; Fig. 5, adetail section taken on the line a' a' in Fig. 3; Fig. 6, an elevation of the operating cam-wheel detached and on an enlarged scale; Fig. 7, a detail front elevation of the breast-plate on the same scale; Fig. S, a detail plan of the plungenbolt and cord-holder on the same scale; Fig. 9, a perspective View of the cutter-bar and cutter on a still more enlarged scale; Fig. 10, a perspective View of the tucker detached on the same scale; Fig. 11, front and edge elevations of the bracket in which the upper end of the butt-adjuster is mounted on the same scale as Fig. 7; Fig. l2, a detail section taken on the line y y in Fig. 1 on the same scale; Fig. 13, an end elevation showing the gear-train between the driving-shaft and main gear of the binder, and Fig. 14 a plan section taken on the line v o, Fig. 13.
My invention relates to harvesting'machines which are provided with automatic grainbinders, and especially that class of grainbinders in which cord is used for the band material.
The invention consists in certain specific improvements in various-parts ofthe machine,
and I will proceed to describe in detail theA construction and operation of so much ofthe machine as is necessary to a full and complete understanding of my present improvements, and will then point out definitely in the claims the particular features which I believe to be new and .desire to protect by Letters Patent.
In nearly all of its general features the harvesting-machine may be of any ordinary con- (Model.)
l struction, and therefore I have not shown a full and complete machine in the drawings, and shall not here describe in detail all the parts which are necessary to a complete work- 5 5 ing machine, but shall only describe those parts which are necessary to an understanding of the construction and application of my present improvements.
In the drawings, A represents a portion of the main frame ofthe harvester at the outer or stubble side of the machine where the binder is located, a the elevator-frame, and A the usual main supporting-wheel. The crankshaft B, which drives the cutters, is here shown as arranged outside of the supporting-wheel, and by means of a sprocket -wheel, b, and drive-chain b motion is communicated from this crank-shaft to the main drive-shaft O of the binder, which is provided with a sprocket wheel, c, to which the said chain is applied.
The binder is of a well-known type of the class provided with an automatic tripping mechanism when the bundle has reached a certain size, and many of the features of this mechanism are so well known as not to require description here; hence I shall restrict the description to those parts which I have improved, referring to such common and wellknown parts of the mechanism as may be necessary.
There is a great tendency in theseharvcstf ing-machines with binders to sag, especially inside ofthe main supporting-wheel. To counteract this,I mount a bracket, D, on the end of the main frame outside of theLmain wheel. This bracket extends from the lower crossbeam to the beam above, as shown in Fig. 3 of the drawings. On the inside of this bracket is a stud or projection, d, and a truss-rod, d, 9o is passed over this projection and then extended outward to the front and rear corners ot' the main frame,to which its respective ends are attached. In this way I obtain a supporting-truss which also resists the inward strain, because its end attachments are considerably outside the vertical plane of its central sup-` port, so that the truss resists not only a vertical thrust, but also a lateral one to a very con- Sider-able extent, as shown in Fig. 14 of the roo drawings.
The drive-shaft C of the binder is provided v.lO
with a clutch and pinion, C', common to this class of machines, the clutch having the usual arm, c','againstwhich the stop-arm acts to throw the binderout of operation. That has heretofore constituted the stop-arm E and crank-arm to which the operating-pitman is attached I make in two separate pieces, eand e', the rst of which is properly the stop arm, and is mounted loosely on theshalt, whilethe sccond,e,is rigidly attached to the same shaft and is connected to the main pitman f. The
' loose arm e is arranged above the journal of ed. An eyebolt, G', is also pivoted on the same journal as the lever, and is thence extended up through an opening` in the arm e,
and is surrounded bya spiral spring, g', above the stop-arm. being provided with a nut, g2, on its upper end, by means'of' which this spring is held in place and adjusted.
The con'ipressor-shaft H is arranged as usual, and an elastic pitnran, h, is connected thereto bythe crank-arm H', as usual, the upper end of the pitman being connected to the main gear-wheel in the usual Way, and arranged `set in motion.
and operated as usual,so thatfurther description is not necessary here. The crank-armH is, however, provided with atail-piece or projection, h', extending beyond the compressorshaft directly under the curved end of the lever G, being provided with a small roller, h2, which works against the saidlever. I is mounted on a hinged support, 1I, in awellknown way, the latter being connected by a link,-t', and crank-arm@nl to the compressorshaft H. Now, it will be kseen that as `the grain is accumulated against the trip by the packers the latter will yield, as usual, thereby oscillating the compressor-shaft, which will lift the end of the lever G and thereby lift the stoparm against the spiral spring arranged above it, until finally it isfdisengaged from the clutch-arm and-the binding mechanism is The automatic trip mechanism is therefore in this instance operated from the trip throughthe compressor-shaft and in connection with the usual compressing de,- vices,t`nereby obviating the employment of a special shaft and devices for this purpose.-
When the compressing devices have operated as usual and return to their nominal position, the stop-arm will be set in position at the proper time to engage with the clutcharm in the usual way, and will be held in this place and compelled to engage with the clutch-arm by means of the spring above it. AThe set-screw in the lever permits an adjustment of the latter in relation to the stoparm .The trip.
so as to secure a. perfect'working of the parts at all times and to compensate for any wear or imperfection in construction of these parts.
The main gear-wheel F of the binding mechanism is mounted on the usual main shaft. f',
and on the inner portion of this shaft is a,
wheel, J, in the usual position of the cam-Lv wheel of this class of binders, where only a single cam and gear wheel is used. This wheel J in this instance, however, is simply provided with ashort gear section or sections, j, arranged to give the required revolution or revolutions to the knottinghook. Theeamwheel K is mounted on this shaft, near the inner end thereof, and, as shown in thek drawings, is of skeleton form and dishing in shape. The outer rim, It,` of this wheel is of irregular form, as shown in Fig. 6 of the drawings,'and acts as a cam for the purpose of reciprocating the bar which operates the-tucker and cutter, as will be presently described. rim, on the face of the wheel, is a catnway, k',
which is a simple' flat surface plain all the way round` except at' one point, where it has Inside of this a sharp projection or crown, k". 0n the in side of the cam-rim k at a certain point isa short stud or projection, k", as shown in Fig. Got' the drawings.
The cord-holding device is composed of a notched disk, M, and a. grooved plate or keeper, M, which is pivoted at the inner end, i
m, and is provided with a spring, m', at its back to hold itin its place. The notched disk is also provided with a ratchet-wheel, m,*,with
which a pawl engages to give-the required intermittent motion' to the disk. These parts -jlust mentioned are of the ordinary construction,except the ,pawl, and vneed no further description.
In most machines of this type the plungerbolt N is employed to turn the notched disk. I have devised sortie improvements, however, in the Inode of accomplishing this result. The plunger-bolt is provided witha spiral IIO spring. u, as usual, which operates to force it outward and hold its outer end, which is prof vided with a roller, n', against thecamway k. The dog or pawl O is pivoted at its inner end Ils-- to the bent arm or bracket O', which at its` other end is vhung on the plunger-bolt between the end of ythe spiral spring and a collar, n. AA suitable spring, o, is provided,by means-'of which the pawl is heldto engage with the ratcheton the notched disk. From the construction and arrangement of these parts, as shown in Fig. 8 of the drawings, it `will be seen that, whenever the cam or projection k is brought against the end of the plunger-bolt the latter will be forced inward, carrying with it-the arm O' andthe pawl O, and thusgve a 7 so that thepawl follows the ratchet with cersasea.. s
tainty', and there is no danger of failure in ac tion. It will also be seen that this device is very simple in construction and is composed of very few parts.
A bar, P, is mounted on the lower portion of the breast-plate Q, being held in suitable ways,g, which permit it to slide back and forth across the opening in the breast-plate through which the cord passes. To this bar is. attached the cord guide and stripper p and the cutter p, as shown in Figs. 7 and 9 of the drawings. Near one end of the bar are two pins, p2, which are arranged to receive between them the cam-rim k of the wheel K. On the back ofthe bar, just inside ofthe pins. there is also a recess or shallow notch, p3. The tucker Ris pivoted to the breast-plate, and is provided with two lugs, r r'. projecting from its journal, as shown in Fig. 10 of the drawings. the former being shorter than the latter, and arranged to enter the notch p3 in the sliding bar, as shown in Fig. 7 of the drawings. Now the cam-rim lc is so constructed as to give the. required reciprocating movement to this sliding bar as it revolves between the pins thereon, and in the process of binding the first movement of the bar is in the direction of the arrow in Fig. 7 of the drawings, whereby the guide carries the cord inward in the proper position to be taken by the hook, and the tucker is thrown down, the projection r turning out of the notch. The bar is held in this position until the knot is formed, and the band is required to be cut, when a still further movement is made in the same directioh, thereby bringing the cutter into action, when the bar is reciprocated in the opposite direction and the tucker is thrown up, this latter operation being assisted by the projection on the cam-rim coming in contact with the lug r' on the tucker.
I provide a bracket, S, in which the buttadjuster S' is mounted. This bracket is angular in form. as shown in Fig. ll of the drawings, and is mounted on the upper elevatorshaft, which passes through an aperture, s, therein, the bracket being fastened to the side ofthe elevator-frame. The upper branch of this bracket contains lsimply a journal-bearing for the upper end of the shaft, s', of the buttadjuster. The lower branch has at its end a socket-bearing, s2, for the lower end ot' this same shaft, on which is tixed a bevelpinion, s3. The bracket is also provided at its end with a spindle, 3*. set therein and projecting out at one side. on which is mounted a short shaft, S2, having at one end a bevelpinion, 85, which engages with the corresponding pinion on the adjuster-shalt, and at the other end the pinion s6, which gears with the corresponding pinion on the elevator-shaft, from which mot-ion is communicated to the apron of the butt-adjuster.
The slatted apron S2 of the butt-adjuster runs around the upper shaft, s', b v which motion is communicated to it and the lower shaft anda lower journal, sl, which is mounted in and between the branches of a forked support, V. The stein of this support, c, is turned down at its upper end somewhat, and passes through a cross-bar, c', in the fra-nie of the adjuster,-
and at its upper end is inserted in an aperture in a similar cross-bar, c", between which and the enlarged portion of the stem it is surrounded by a spiral-spring, v3. The arms Q2* ofthe fork of this support are set in suitable grooves in the upper and lower pieces of the frame, so as to permit a sliding or lengthwise movement of this support. It will thus be seen that the lower journal of the apron is yielding to acommodate any change in the canvas ofthe apron, and at the same time the tension on the latter will always be preserved to the required degree by the operation ofthe spring.
I also provide an apron or grain-guard, T, which I binge at its upper edge to the upper part of the elevator frame, from which it projects downward and outward over the incline to which the grain is delivered. A hand lever, t, is attached to this apron and arranged within reach ofthe driver, so that he may adjust it atwill, and any suitable device may be provided for fastening the apron in any desired position. In this instance I provide a series ot' pins, t', near the end of the lever, which passes through a link, t, and the apron is held in any desired position by adjusting the link over one or another of the pins. A keeper, T', may be pivoted to the lever, so as to swing over the top of the pins to prevent disengagement of the link, if desired.
In the usual arrangement of the gear-train between the pinion on the lnain drive-shaft of the machine and the main gear-wheel of the binder the gears are allot' one size and provided with the same number of teeth, and have a certain relation to the main wheel, so that they stop at the same toot-h with each revolution of the latter. The wear is therefore greater at this point than any other, and there will soon be somelooseness between the gears, so as to occasion some inaccuracy in the action of the stop-arm. To avoid this, I make the gears of this train with a different number oi'4 teeth, so as to breakup the regularity of the stopping place. In the drawings, I have shown four gears in this train, U U U2 U3, commencing at the driving-pinion. The first and last of these in this instance, as shown in Fig. 13 of the drawings, are provided with fifteen teeth, while the two middle ones have only fourteen, which construction and arrangement will obviously break up the regularity of the stopping-places mentioned above.
I have described the operation of the several parts of my invention in connection with the description ot' their construction and arrangement, so that it is not necessary to give another statement of the entire operation of binding a bundle. It will be understood, however, that the devices described are timed in relation to each other and in relation to IOO the other parts-ofthe binder, so th'at the usual well known steps in the process of forming a bundle, binding, and discharging it in'this vrangement of all the devices as herein described and shown, for they may be modified to some extent and still retain the gist of my invention. -It is also obvious that these devices are not all necessary to each other in the same machine; but some of them maybe applied in connection with other different devices for performing the functions of those with which they are here associated.
Having thus described my invention, what I claim as new, and wish to protect by Letters 1.
