SPCIFICATION forming part of Letters Patent No. 422,601, dated March 4, 1890.

Application filed May 1l, 1883. Serial No. 94,633. (No model.)

To @ZZ whom it may concern:

Be it known that I, SYLVANUS D. LOCKE, of I'Ioosick Falls, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Harvesters, of which the following is a specification.

In Letters Patent granted to me on the 6th l day of April, 1886, numbered 339,561, I have described improvements in harvesters of the Marsh type-that is, provided at the stubble end of the platform with an elevator bridg-v ing the main or driving wheelewhich improvements have for their object, mainly, to reduce the depth of the machine by allowing the stalks of long grain to project at the rear of the platform and beyond the elevator as they are carried up to its head and delivered over into the binding-table or grain-receptacle.

The present invention relates inA part to improvements upon harvesters of such oonstruction and in part to improvements applicable to harvesters generally as Wellas to this; and it consists in combining with the platform and overhung elevator an extensionboard hinged at the rear of said platform and adapted to be opened into a horizontal position to support the heads of long grain falling thereon; in combining with the overhung float or frame supporting the upper apron of the elevator a latch pivoted to the rear inner elevator-strut and catching upon a pin on said overhnng frame to support it in transportation or when the grain is short; in an arrangement of shafts and beveled gearing to drive the platform-apron and the upper roller of the lower elevator-apron directly Ifrom the shaft at the stubble end of the elevator; in mechanism for drivingthe reel from the roller at the head of the lower elevatorapron; in improved devices for adjusting the reel in and out and up and down; in combining with the hinged tongue an elbow-lever pivoted to the framework at the front of theV binations and details of construction hereinafterpointed ont and claimed. In the drawings, Figure l is a rear eleva# tion of a harvester constructed according to my invention,showing a binding attachment i to explain the purpose of some o f the parts; Fig. 2, an elevation from the grain end of 'the machine, with the platform in section; Fig. 3, a front elevation showing only the inner portion. of the platform and reel; Fig. 4Q, a vertical transverse section on the line-'indicated in Fig. l, looking from the stubblesi e;

A is the platform, and A the elevator-frame; A2, the main wheel turning upon a short axle, having fast pinions at its ends engaging with segment-racks fixed to the cross sills or timbers a beneath the elevator, and rotated to adjust the wheel up and down by means of a worm-shaft a and worm-wheel a2, or in any other suitable manner. The prime-pinion shaft a4, driven by this main wheel, carries a beveled gear a5, having two concentric series of teeth, the outer series driving the cutter crank-shaft a for speed, and the inner series a rearwardly-extending shaft al in lin-e with the crankshaft, but passing through a bearing on the rear sill and receiving beyond this. a double beveled gear a8, whereby the plat-- form-apron and lower elevator-apron are ultimately driven. Speed-gearing a on this shaft also drives a counter-shaft am, which by means of a sliding wheel or wallower communicates with the main gear of the binder.A Clutches and levers, arranged substantially as in my formerA invention, control the movements of this train of gear and the speed to be given to the binder.

Above the elevator-frame is a float or upper apron-frame B, overhung from the front of the machine. Herein it is shown and is preferably constructed as an apron -frame and not as a mere float.

The rollers and the weight of the canvas apronitself require it to be strongly supported; In order to accomplish this and at the same time to retain the radvantage of allowing the heads of long grain to project, saving in the depth and weight of the machine as a whole, I have deemed it advisable to supply a supplementary support, which maybe used whenever, as often happens, theV grain is for a long time of an average or stunted growth, not calling for any space beyond the minimum depth of the machine, and may during such period, and also when the 1nachineisbeing transported, serve to support 'firmly the rear of said upper frame from the underlying elevator-frame, saving it from being strained or racked, and preserving its strength and integrity for such time as the grain is heavy and of extra length. Such a su-pport is furnished by the latch b, pivoted to the rear inner elevator-strut and catching over a pin b upon the rear bar of the frame. When demanded, this latch can be thrown back, and will then either hang upon its pivot or rest against a stop afforded conveniently by a bracket-casting 112, in which is collared the crank-rod for adjusting the angle between the frame and the draftftongue, as will presently appear.

The heads of long grain as it falls upon the platform ordinarily project and sag in the rear, and, as the platformV is low and near the ground, are liable to be caught and dragged by tall stubble or by sticks or other obstructions in the field, pulling the grain olf. In

`one instance asliding extension-board has been attached to the rear sill of a harvester of analogous construction to support such heads. This, however, left the top of the platform clear and exposed to the wind, which is apt to sweep short and light grain off, while long and heavy grain is generally too stable to be aiected byit. Instead of such sliding board, in the present instance a hinged board B is used, being secured by pivot-bolts b4 to l ears bprojecting from the rearsill, and form# ing when it isvertical an eicient wind-board,

, afford-ing, on the other hand,when itl is, down, a shelf or extension to. support the heads of projecting grain. sition its pivot-bolts may be supplied with To secure it in either poclamping-nuts 116, by which the hingiing-straps can be bound in friction contact with the ears,.holding it rigidly in Whichever position it is placed.

roller B3, supporting it at its innerend. This `roller is journaledin a casting of malleable j iron B4, which servesas a strap to bind the two sections of the rear sill at their junction beneath the inner elevator-strut. Such cast# ing is also formed with an angular lange or seat 117,. which receives a. second or smaller casting b3, comprising a hood shielding the beveled pinion on t-he gudgeon of the apronroller, and also a step or bearing b for the end of the light shaft 11,10, running obliquely from this point to the outer face of the-double beveled gear at the lower stubble side ot? the elevator, and meshing therewith by a beveled pinion. A singlebolt secures thehood and bearing-castingin place upon the other.

The rear journal of the upper roller C of the lower elevator-apron has its bearings in a casting C', formed substantially as shown in Fig. 10that is, with a hood c to. protect the gearing at such point, lateral arms c", one of which is bolted to the outer and the other to the inner elevator-strut, to tie the two togethervat their junction, an elongated tubular bearingcwhich enters through the woodwork and gives a metallic seat to the gudgeon of the roller, and a pillowblock c, whichA receives the upper end of the light shat't c4, engaging by beveled pinion c with the beveled wheel c'I on the end of the roller-gudgeon, and running obliquely from this point down along the outer elevator-strut to the innerl side of the before-mentioned double beveled gear at the base of said strut or outer lower corner' of the elevator, with which wheel it also engages, so as to be driven thereby through the medium of a beveled pinion.

IOO

IVIO

To retain the three shafts which meetat this pointi. e., at the lower outer corner-of the elevator the shaft running horizontally beneath the elevator from the beveled wheel on the prime-pinion shaft, the shaft running horizontally along the back of the rear sillto the inner end of the platform-apron and driv-A ing said apron, and the shaft running yobliquely upward to the head of the lower elevator-apron to drive the latter--in permanent relation one to another, and to prevent the intermeshing gears from being disarranged or thrown out of engagement by any springing or starting relatively to each other of the bearing of this shaft, said bearings are preferably all formed in a single block of metal D. (Represented in detail in Fig. I6.) This is bolted' to the top of the rear sill at said point, and has, first, a transverse bearing d, receiving the horizontal shaft; second, a vertical inclined bearing d', in which turns the ascending shaft for the elevator-apron, and,tl1ird, a horizontal or nearly-horizontal bearing d2 for the lateral shaft driving the platform-apron, said bearings being so related to each other as to bring the ends of the shafts in proper position. to` cause a perfect fittingof the'gear-wheel and pinions at this point. In addition to the bearings, the vertical standard Whichrises from said casting to afford the bearing for the elevator-shaftV is formed with a seat for the reception of Vthe l segment-rack d4, in which the change-speed lever Z5 latches, said segment being bolted to the standard and having a fiange which clasps one end thereof, making a firm and steady connection. The pivot-pin for the lever passes through the segment anda fiange of the standard, and forms, or may form, one of the fastenings for securing. the two together. It should be mentioned that the casting at the apex of the rear elevator-struts, in addition to the functions already stated, projects sufficiently above the apron, and necessarily s in order to form the hood, to serve as a keeper or guide to said apron, preventing it from. working laterally over the roller and projecting at the rear.

To further carry out my purpose of making strong and perfect connection between the various members of the train of gearinginvolved in the' machine and to preserve perfect rela.- tion between the shafts and metallic supports, as well as to reduce the labor of assembling or building up, and the number of parts or pieces of furniture, the arrangement of gearing and relation of bearings for the shafts of such gearing have been so modified as to enable a triple or even quadruple burden to be performed by 'single castings, thus so far reducing their number that practically all the import-ant labor devolves upon two, the first of which-the casting E at the front part of the frame-#receives the cutter crank-shaft in a long sleeve-bearing c', carries upon alateral bridge from the sleeve one end of thc feathered shaft upon which the wallcwer trav'- els, and finally, in eyes e2 at the outer foot of this bridge, supports the adjacent ends of the Vouter foot of this bridge, projecting beyond the stubble-gilt, an eye f3, supporting the rear end of the adjacent or hindmost guiderod for the binder. The first of these bearingcastings may be secured tothe frame by ,three bolts and the second by two. Besides ,these two and the one already mentioned atthe rear which supports the ends of three shafts, there need be in theA construction shown, beneath the elevator, but two inde'- pendent bearings--one for each end of the prime-pinion shaft, and the clip or eye f* for the forward end of one of the binder-frame guide-rods.. In machines of this nature the elevator-frame must be strongly trussed, since it braces all the other parts of the harvester.

,In all harvesters of this typcthere is a great tendency of the platform and alsovof the elevator to twist and sag out of shape, causing derangement of the apron or belts and other operating mechanism and general roo ricketiness of the machine. This is due to the great weight and size of this form :of harvester and the'rough usage to which it is subjected. The'twisting of the platform is very lobjectionable and has not heretofore 105 been wholly prevented', as owing to its thinness it has not been found practical to truss it. This twisting of the platform is `usually accompanied by a corresponding sagging of the elevator to the front or rear and a twist- 1 ro ing of the elevator-frames that cause the aprons or canvas both to crowd towardrone end of their carrying rolls or drums, and so .inducing great loss of power and' great wear of the edges of the aprons. In some of my 115 former machines I partly succeeded in remedying this difficulty and tendency by the use of a tie-rod along the longest (or that which tended to be longest) diagonal of the elevatorframe, which in my old machine was from 12o the rear sill at the base of theinner elevatorstrutto the apex of the frame atthe junction of both front struts0 Any sag or deflection was taken 'up by means of a -nut or turnbuckle; but in practice, with the weight of 125 the binder, rechtbc., differently placed and on rough ground, it was found that this rod was often better if i made a brace instead of a tie, or that it was moreeffectiveif extended from the opposite corners of the elevator- 13o frame or at right angles tothe position I had given it. Such tendency of the platform to twist and sag and such sagging and twisting of the elevator-frames are fully met and overyIO come by the insertion of rigid brace-bars gx in the inner or ascending elevator-frame, one extending from nea-i' the foot of the rear innerstrut diagonally up to the front inner strut, and the other fi'oin near the foot of the front inner strut diagonally up to the rear inner strut. In practice I also add a horizontal bar g, which connects with the outside descending inclined struts, and is bolted or otherwise fastened at the crossing of a second pair of brace-bars g', located within the outside descending frame formed by said struts and their basesill, the horizontal bar first named serving to support and afford a track for the inner edge of the sliding binding-table, as well as to stiifen the brace-bars and render rigid the struts. In said previous patent, also, the tongue I-I, hinged to the main frame, was connected to an elbow-lever h, pivoted to the elevator frame and controlled by means of a crankrod 71 collared into the power-arm of said le ver and threaded into a female screw in a keeper h2 at the rear of the elevator, said crank-rod, therefore, as it was turned, working back and forth toward and from the drive ers seat, which is advisably supported from a rearwardly-extending bar, as will be remembered; but in the present ease, since this rod and its crank at the rear may otherwise at times be. turned so far back as to interfere with the driver or be inconvenient for his use, it is preferred to fasten it by collars or lianges against endwise movement relatively to the keeper and to form its forward end with screw-threads, which take into a swiveled nut h3 in the power end of the elbow-le-4 ver, so that as the rod is turned said lever maybe` operated to raise or depress the drafttongue without any lengthwise movement of the rod. The nut is secured in the proper arm of the lever by trunnions, one of which takes into the arm itself and thesecond into a clip correspondingly shaped and fastened to said arm by a bolt, so that it may be readily removed in dismounting the machine.

The upper apron of the elevator has formerly been driven in various ways, notably by a eliain'belt,which, starting from the main shaft, or that shaft ruiming horizontally beneath the elevator and terminating at the rear, led over a sprocket-wheel at the inner end of the platfor1nbelt, then up to one or the other of the upper elevator-rollers, extendingfrom the first to the next, and finally down to the starting-point. Herein it is driven as follows: Upon the froiitgudgeon of the liead-roller of the lower elevator-apron is a gear-wheel t', connecting with a second gearwheel i', of equal diameter and number of teeth, on the gudgeon of the roller of the overlying loateapron, so as to drive the latter; and for the purpose of supporting the gudgeons ofthese two elevator-rollers at the head of the frame, and for bracing the struts aiid the windboard in front of the elevator and binding-table, and also for the purpose of support `per trackway for the binding-frame, a east-y y a diagonal tie.

ing an overhung bar I, which receives the up4 ing I is employed, bolted to both of said struts, to the crosspiece at the apex, and to said overhnng bar.

The reel is supported upon two posts K at the front of the elevator, which are braced by The post on the platform side is secured to the harvester, in addition to other fastenings, by a casting K', having an npriglit flange 7c bolted to said post,a diagonal Iiaiige k embracing and bolted to the end of the cross-timber connecting the front and rear Qinner elevatorfstruts just above the main sills, and a third lateral flange serving as a seat or support for a rod 7a2, bracing the nose of the inside divider and secured to the front inner elevatorstrut by the same bolt securing said rod.

The post on thebinder side is also additionally secured at its top by a strap casting K2, which is bolted at its main web or `body to the front board of the elevator, is

.bent up and over from said web in one direction to form a keeper k3 for the reel-post and a bearing 7a4 for the reel-pivot, and in the other direction is thickened and set out from the board to afford a second bearing c for the extreme inner end ofA said pivot-rod anda short stub-spindle k6 for the dis hed geai'u'lieel below mentioned.

The reel-f rame L is, as usual in modern har i vesters, composed of two bars Z, hinged to the supporting-posts by the pivot-rod l', and serving for the in and out adjustment according to their flexions upon the hinge, a yoke l2 comprising two other bars hinged to the first pair, and serving as they fold thereupon or are raised therefrom to lift or lower said reel. The pivot-rod carrying the first pair of bars,

and ultimately the whole reelframe, is borne at its platform end in a short bracket rising from the corresponding reel-postand at its stubble end in the two bearings afforded by the casting K2, and it receives between the ltwo latter the long hub of a 1oose-running p of the lower elevator-apron shaft or gudgeon at the head of said elevator and in advance of the wheel on said gudgeon which drives the upperapron. A sprocketfwheel m upon the pivotal gear receives a chain belt M, which runs to another sprocket-wheel m upon the end of a shaft mi, forming the pivot between the first and second pair of reel-supporting bars, and from the other end of the last-nientioned shaft a chain belt M connects, by chain-wheels m m, with the reel-shaft mi', borne, as above stated, in the outer end of the second pair of bars, so as to turn a reel of the usual construction.

To one of the bars serving for the in and out adjustment of the reel-preferably the bar on the grain side of the harvester-is fixed a IOO IIO

segment-bracket n, described on an arc concentric with the axis of said bar, and to that axis is pivoted a lever N, extend-ing rearwardly within the reach of the drivers seat,

' lever has a small hand-lever near to its handhold connectedv by a link with a spring-dog engaging with the teeth of the rack, and ata point near said rack is connected' by a link n wlth a rearwardly-extending heel-piece from the yoke or one of the bars serving for the up and down adjustment of the reel, so that by raising or depressing the lever and locking it in position the height of the reel may be determined. If this latter lever alone werefthe instrumentality to secure the reel in.v position, it would, whether free from its rack or locked therein, only maintain the angle between the two sets of supporting-V bars and the reel might drop by its own gravity. `The lower' set of supporting-barsthose for the in and out adj ustm'entfmust therefore be supported from the harvesterframe, and for this purpose they have attached to them keeper-plates litz-#one to each, with diagonally-set fingers-and are perforated behind the bars to Yreceive the right-angled bent endsof tines n3 from a forked brace bar or link N extending to the rear of the elevator-float or overhung apronframe, and therejointed toa lever N2, which locks by means of its dog into a segmentrack n'upon the lower 'supporting-bar cf said overhung frame or any other suitable base, the arrangement thereby serving to brace and hold the reel in fixed position and at Jthe same time for its adjustment in and ou To describe alittle further, the keeperplates and their fingers are attached to the respective bars of the lower pair so that the lwith its lever without interference from the iingers; but immediately after beingv so inserted the brace is to be 4carried down, bringing its arms or-tines inside the fingers, which will restrain them from leaving the sockets, and the brace will then be secured to the lever at its rear end, as above explained.

The front sill O of the platform-frame, forming usually part of the iinger=bar, extends as toits length in the same direction and to the same extent as heretofore; but to raise the butts of the grain over the elevator,which butts have often been delayed by their contact with the finger-bar, both'lower and up per elevator-aprons are advanced in front of the platform-apron. W`ere the'front sill of the same dimensions throughout, the lower elevator-apron must be raised at its foot toa level with the top surface of the platform apron, and grain might escape between the two. To avoid this the wooden front sill is recessed or hollowed on the inner side of the platform-apron to admit the lower roller and bight of said lower elevator-apron, and that it may not be weakened by such loss of ma-v terial a casting O is bolted thereto along the inner side and provided with a flange 0, sup porting the bottom of said sill just beneath the cut-away portion, and a secondvcupped' iiange 0, entering and lodging upon the cutL away portion, strengthening and guarding against splinterin g or wear 'from contact with the belt.

'j In the use of canvas aprons or belts a great drawback is encountered in the difficulty of keeping them in proper alignment with their driving rolls or drums. This dithculty is particularly marked in the use of the platform-apron, and is due to several causesas the twisting of the platform, the unequal tightening of the straps by which its ends are united, and the unequal wetting'and consequent unequal shrinking by wet' grain.` These all induce the apron to run sidewise or toward one end of the driving roll 'or drum, and as the upper fold of the platfor|n-apron approaching its driving-roll is necessarily unguided by a wall or fence against which its edge may abut, it not unfrequently is so it endwise of the roll into Aits proper position. To avoid this serious difficulty, I employ an inclined guide or cam o2, against which the ends of the cross-slats on the apron strike just before they enter upon the driving-roll, andv by which they are driven back, if out of alignment, so as to enter squarely on the roll. This guide is most needed at the forward edge of the apron next to the cutter-bar, as,owing to the fact that the forward .side of the canvas is often made quite wet and so unduly taut, while the rear side is dry and compara-A tively loose, and also owing to other causes, as the inclination forwardl of the platform, the tendency of the apron is to run off ofthe forward end of its driving-roll but preferably I provide the rear as well as the forward edge with such guide o2 and locate the two guides just in advance of the roll, so as to adjust the apron before it enters and becomes rigid over theroll. The forward guide on my machine it is preferred to make a partef the above-mentioned casting O', forming itas a raised and inclined guiding-flange thereof,

' J ust beyond the'depres'sio'n in the front sill,` on-the stubble side thereof, isa bracket P,

having a channel p to guide the heel ofthe cuttebar P', and insidev of 'said channel a IOO to the tension ofthe apron, impossible t0 slide IIO ISO

ledge p of sulicient space to admit the thickness of the pitman I, which at its en d is bent at right angles, so as to enter a socket in said heel, in which it will be retained by the vertical web p2 of the bracket until such time as it is released from its crank-pin and the cutter-bar drawn out of the bracket.

In recent times the finger-bar has almost invariably been constructed of angle-iron with a wood backing, the guard-fin gers being bolted to the upper horizontal flange of said angleiron. This is an expensive and inconvenient construction, and I have discarded it, and, preferably, all other metallic bars, choosing to utilize the wooden front sill as the main support of the guard-fingers, which is done in the following manner: To the rear of this front sill is applied a bar q, serving as the ordinary guide-bar for the support of the apron-edge, and in front of the sill opposite the first-named bar is placed a second bar or strip q', secured advisably by through-bolts, binding all three together.

The sill and front bar are beveled forwardly, as shown, to facilitate the reception of grain. Beneath the front bar and close to its edge the sill O is bored horizontally with a series of sockets or holes q2, and the guard-fingers R are formed with spindular shanks r, which enter said recesses or sockets. Bolts r pass vertically through the front bar and enter into the shanks of the guard-fingers, to which they are attached by nuts, thus completing the fastening. Otherwise the guard-lingers are 0f the usual form. The back of the cutter-bar in this connection is retained, and plays against clips or keepers r2, which consist, individually, of an irregular T-casting, so shaped and applied that the extremities of the short arms are secured by two adjacent guard-finger-fasteningbolts, andthe long arm rises between these respective guard-fingers, sits firmly against the face of the front strip to receive the backward thrust of said cutter-bar, and bends forward snugly over its top to prevent its escape. Such keepers will be applied at regular intervals, but need not correspond in number with the number of spaces between the guard-fingers.
