SPECIFICATION forming part of Letters Patent No. 402,807, dated May 7, 1889.
Application iiled .Tune 30, 1888. Serial No. 278,606. (No model.)
T0 all whom t may concern:
Beit known that I, HENRY MCKINDRY CoE- FEE, of Bunker Hill, in the county of Macoupin and State of Illinois, have invented certain new and useful Improvements in Straw-Stackers; and I do hereby declare the following to be a full, clear, and exact description of the inventicmsuch as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improvement in straw-stackers.
The object is to provide a machine adapted for use with ordinary thrashing-machines, and at the same time one which shall be light, comparatively simple, and inexpensive, with its mechanical parts reduced to a minimum, and a machine that may be folded to occupy a small space during transportation.
A further obj ect is to provide a novel means of raising or lowering the carrier to suit the height of the stack without ip any way interfering with the progress of the machine.
A further object is to provide means for automatically swinging the stacking-elevator back and forth and regulating its length of sweep to suit the size of the stack being built; and a still further object is to provide a self-adjusting device for conveying the straw from the thrasher to the stacker, and one which at the same time will prevent the straw from blowing and falling around the stacker, and in fact practically guard the whole machinery of the stacker against being covered and clogged with straw, chaff, and dust.
fith these objects in View my invention consists in certain novel features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.
In the accompanying drawings, Figure l is a side elevation of the stacker in position for transportation, with the stackingelevator folded. Fig. 2 is a similar view showing the stacking-elevator extended and elevated, the parts being in operative position, and showing the mechanism for automatically reversing the swing of the stacking-elevator. Fig.
3 is a front elevation of the machine with the straw-transferring attachment removed. Fig. 4 is a detailed view of the mechanism for regulating the length of sweep of the stacking-elevator. Fig. 5 is an enlarged fragmentary view of the reversing mechanism shown in Fig. 2; and Fig. 6 is a detached view of bow 40, with the connected swivel-block 39.
A A represent the main side sills of the machine, extending parallel with each other and inclining slightly downward toward the rear end of the frame. To the forward end of these sills the front standards, B, are secured, and to the rear end arms F are braced. This frame is supported on bolsters C. Blocks D are aflixed to the lower faces of the sills, and to these cross-piece K is bolted. A pair of uprights, E, project vertically from the sills A A', and across their top is the cross-piece E. Braces e extend from this cross-piece to the standards B.
' Stepped in a box, k, on the cross-piefce K, midway between the uprights E,is a rocking shaft, G, the upper end of which is journaled in a box, e', projecting rearwardly from crosspiece E. To this shaft a brace, H, is rigidly secured near the upper and lower ends, thus forming in effect a crane of great strength, to the outer end, h, of which is pivoted a lever, I.
U represents a strawstacking elevator formed in two sections hinged together. Rolle s u are j ournaled in the opposite ends of these sections, upon which an ordinary endless-belt conveyer is carried. The side-boards U are fastened to the upper edge of the elevator to guard against the straw dropping over the sides. The rear end of the elevator is supported by arm .I pivoted to the end of lever I. To the upper end of rocking shaft G cross-piece 'Q is rigidly secured, and to the outer ends of this piece the arms V are pivoted on pintles o, said arms also being pivoted at their upper ends to the forward end of the elevator.
An arm, XV, is rigidly secured to cross-strips 50, connecting arms V, and this arm IV projects rearwardly and is provided at its end with a sheave, l-l. A cable, 4, secured at one end to shaft G, is passed over sheave l-I, and
its opposite end is secured to lever I, nearA the forward end of the latter. A sheave, Y, is also journaled in the forward end of lever I, as is also one, Z, in the lowerlimb of brace Swivel-sheave 7 depends from cross-piece IOO K, and a windingdrum, 2, having a crank, Q, thereon, is supported beneath sill A. A cable, 5, securely fastened at one end to the lower limb of brace ll, and from this point passed over sheave Y, th en downward beneath sheave Z, then under swivel-sheave 7, and iinaliy to drum 2, where its end is secured. At this stage the parts are in the position shown in Fig. l, the folded elevator being held against lateral movement by arms F. Now, by winding or unwinding the cable 5 on drum 2 the stacking-elevator is raised orlowered. The result of the operation is this: The winding oft-he cable draws the shorter or forward end of lever I downward, thus earrying with it the rear end of arm V, raising the forward end of elevator, as shown in Fig. 2,and the longer or rear end of lever I upward, projecting' the rear end of elevator upward, these parts all operating simultaneously. lt will be observed that cable l is always the same length.
Right in this connection it is well to explain the transferring attachment, as its selfacting operation is dependent upon and regulatcd by the posit-ion assumed by the stack. ing-elevator. This attachment consists of a frame, 2l, pivoted at its forward end on bracket-arms 35, and having -a sliding swivel-connecti on through the pivoted slide-block 3901i bow l0, secured to the attachlnents rear end. llows 2U Q7 are secured tothe elevator, and a rodM/Ttl, is removably bolted to the top of these bows. The forward end of ihis rod extends loosely through block 39 and has a sliding connection therewith. The attaclnnent 2l has a wind-sheet, 25, stretched across its forward end, and may have canvas sides. (lanvas may, besides, be stretched over the bows 2G 27, all these being to prevent the straw and dust being caught by the wind and blown over the working machinery. Within is an endless belt, 453, carried on suitable rollers. An elevator, 12, carries the straw to this transfel-ring attachment. Figs. l and l show two different positions taken by this attachment, and by an examination of these figuresitwill be observed that the attaehmentis absolutely self-acting, of course depending on the movement of the elevator. As the elevator is lowered, Fig. l, the block 3'.) slides down or back on rod Land the attachment tilts downward at its rear end, while, on the other hand,when the elevater is raised, Fig. 2, the block 30 slides in an opposite direction on rod il and is tilted upward-in other words, the elevating-belts of the attachment and of the stacking-elevator always being aliproximatel y parallel whatever the positions assumed.
To return to the more essential and indispensable mechanism of my invention, abevelpinion, M, is loosely mounted on the rocking shaft G, a short distance below the crosspiece Q, and from this point a pair of shafts, S and O, extends in opposite di reetions transversely of the machine. Keyed tothe adjacent ends of these shafts are the bevel-pinhms R and N, respectively. The shaft S is revolubly supported in boxes s, depending from the cross-piece Q. A pulley, T, is fixed on the outer end of this shaft, and an endless belt, T extends therefrom over pulley T, which drives the endless-belt conveyer in the stackilig-elevator. The other shaft, O, is the main driving-shaft. Itis journaled in boxes o on eross-piece E', and a drivingsdrum, O', is keyed on its outer end. Back of pulley a similar one, 1U, is keyed, and a belt, 1 (3', passed over this pulley and also a pulley, l5, communicates motion to the latter. Through this medium motion is given to the swinging gear now to be described. y
The numeral G represents a toothed halfwheel or segment. This is keyed to the roeking shaft G a short distance above the sills A A. short shaft, S, is journaled, and keyed to this shaft is a pinion, l., meshed with thc segment (l. A worm-wheel, il, is keyed to the upper end of the shaft S. lransverse shaft 1l. 'is revolubly supported in journal-boxes on cross-piece il. \Vormwheel 12 is keyed on one end of this shaft in engagement with worm-wheel i), and to the opposite end of shaft ll. an internal toothed gear-wheel, l0, is keyed. Meshed with the teeth of this wheel is a gear-wheel, 17, revolubly supported on a suitable shaft, 17. A shaft, lJf, on which the previously-mentioned pulley l5 is keyed, and through which motion is ennmunicated to the shaft, is in alignment with this shaft ll. On the opposite end of this shaft a gear-wheel, l2), is keyed. The teeth of this wheel are adapted to alternately mesh with the teeth of wheel 17 or the inter nal teeth of wheel l() to change the motion of the laterallyswinging stacking elevator either to the right or left. The position of this wheel l?) automatically shifted by peculiar mechanism now to be described. The inner end of shaft 14 is revolublysupported in a sliding journal-box, 1S. This box is pivotally and slidingly supported on the end of rod 1H', where it is automatically shifted by the following mechanism: The segment (S is provided on its upper face near the periphery with an undercut groove, o, in which the heads of bolts o are inserted. The bolts may be slid around to anypointin the groove and then secured by tail-nuts o2, so that their ends project upwardly above the face of the segment a short distance. The position ol these bolts is determined bythe length of sweep desired for the stacking-elevator. The
nearer they are together of course the shorten.'
ln the arm Z and cross-piece ma.
In the periphery of the crank-wheel or disk GG notches p are 'formed at diametrically-opposite points and preferably at equal distances from the crank-pin. Spring-pawl 64 is placed in position so as to engage automatically the notches of the wheel 66. Connecting bar or link 22 extends between sliding journal-box 18 and thercrank-pin p and is pivotally connected t0 each.
It will be readily seen that when one of the upwardly-projecting bolts o', adj usted in segment (3, comes in contact with one of the springs 03 from the turn of the segment the outwardly-projecting end of the spring will be forced against the arm 20, and when sufficient pressure is exerted to throw the toe on the end of spring-pawl G4 out of engagement with the notch in wheel GG the latter will make a lialf-revolution, stopping again on the other dead-ceiiter, which forms a lock with connecting-bar and holds the teeth of wheels lOAand 123 firmly ineshed, as shown in Fig. 4:. Then in the other position the teeth of wheels l-l and 17 are ineslied, and an opposite motion results. The object of springs o3 is to give wheel 66 a full half-turn and also a yielding contact.
The operation of thestacking-elevator and transferring attachment has been described, and to render comprehensible the modus 0pcrandi of the swinging gear a brief description of the same will ensue.
Motion is communicated through a suitable belt from driving-shaft O to shaft 14, in the direction of the arrow. The gear-wheel 13, keyed to the inner end of this shaft, is slid backward and forward by each oscillation of segment G through the medium of connectingbar 22, crank-wliecl G6, segment 19, and arm 20, so that the teeth of wheel 13 mesh alternately with the internal teeth of wheel 10 and the teeth of gear-wlieel 17, the former engagement operating to drive rocking shaft-G in the direction indicated by the arrow u, while the latter engagement drives the shaft in the opposite direction through the worm- wheels 9 and 12. This change, it will be noticed, is automatic, and the operation of the entire machine is dependent on the single driveshaft O. y
It is evident that slight changes might be resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of my invention. Hence I do not wish to limit myself to the particular construction herein set forth; but,
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
