IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 141,866, dated August 19, 1873; reissue No. 7,144, dated May 30, 1876; application filed March 11, 1875.

To all whom it may concern I Be it known that I, JOHN H. ELWARD, of

St. Paul, county of Ramsey and State of Min nesota, have invented a new and useful Improvement in Harvesters, of which the following is a full, clear, and exact description, ref-.

. embracing my improvements. Fig. 2 is a vertical transverse section of the same. Fig. 3 is a'perspective view of a portion of the elevating-apron and delivery-shield, with intermediate discharging-rollers, and Fig. 4 is a plan or .top' view of the machine, partly broken away,

and airithatheaprons removed, to show the -eoustruction of: the elevator-frame and its re lationto the platform-frame.

Similar letters of reference denote similar parts in all the figures.

' My invention consists, first, in making the broad continuous elevator-apron .of greater width than the platform-apron .orcarrier, and

extending its forward edge in front of said platform-apron for clearing the overhanging butts of the grain and elevating the same, as hereinafter described; second, in the. combination of a. friction-roller, with the: lower end of the yielding spring-board, which holds the grain down to the action of the elevating rake or apron for facilitating the entrance of the grain betweensaid board and rake or apron, aslheneiuaflzer explained; third, in the combination of a'lifting-roller with the yielding compressingboard, whereby either or both ends .of said board mayberaised; fourth, in com hinin g a ribbed orcorrugated dischargin groller with the notched slats of the-elevator- "apron; fifth, in' the combination, with a machine provided with a receptacle for the shattered grain and short heads, of a second el'evating-apron for taking the grain, .after itzhas been discharged from 'thejfirstele vating-aprou or rake, and delivering-it into a carter-wagon by the side of the machine, whereby the grain, when tooripe, or otherwise not in fitTcouditioni to be bound,.may be discharged into such cartior wagon, while at the same .time-athe "flattered grain is caught and saved rand,

lastly, in certain details of construction and arrangement, all as hereinafter set forth.

In the accompanying drawing, A represents the driving wheel; B B, the frame; B, the forward platform-bar; 0, horizontal recsivin gapron C the elevating-apron; D, the discharging-roller, for cleaning the rake-teeth at the point of delivery; E E the inclined delivery-shield, for receiving the grain and straw from the elevator apron or rake, and depositing it upon the receiving-fingers, or into the binders platform and'reeeptacle; F, the-receiving-fingers, sho wnturned down out of the 'way to accommodate a secondaryelevating and discharging apron; G, overhanging pivoted arms, which, when the grain is bound upon the machine, support the longitudinal bars represented in dotted linesin the d raw-- rugs.

Parts of the-'inachi'ne .uot hereinafter particularly 'referred to may be constructed and applied in an y-usual or desired manner.

The finger-bar B or forward transverse bar of the platform-frame, is located at some distance in rear of and below the line of the forward main -frame bar B, and is connected therewith by a strong angular strap or shoe plate, B secured to the lower face of the inner end of the frame-bar B, and to the upper face of .the adjacent end of the platform or finger bar B thus contracting the width of the platform-frame relatively to the main and elevator frames,'.and at the same time setting the finger-bar sntficiently below the frame-bar B to adapt it, although in rear of the latter to be-depressed to the surface of the ground, for picking up lodgedgrain.

The main-frame bar B, at its inner end, is

notched or recessed to reeei vethe lower end .ot the elevator-frame G, in which the forward end of the elevator-O or of its actuatin g-roller,

has its-support or bearin g, thus extending said elevator-frame and roller,.tog'ether with the broad continuous elevator-apron mounted thereon, in front of the forwardxedge of the platform apron or carrier. This le-important, from.- the fact that the-barbed2heads of the grain adhere more closely rtojlthe platform- :apron, and 'arecarried forward more rapidly. Reaching the el'evator-aproniin advaucexofthe -bl1fl38, and beingthere'retardedpntil-thalmtts e rears-ass overtake them, thelatter are swung forward and caused to overhang the forward edge of the platform-apron.

By extending the elevator-apron forward 01 the forward edge of the platform -apron, as described, all obstructing stationary surfaces are removed out of the wayof the advancing butts of the grain, and by making the elevator in the form of the broad, continuous apron, as described, equality ot' movement in the elevation of the heads and butts is secured.

H H are sent-supporting bars, which over hang the inner or upper face of the elevatorapron C and are connected by the longi-tudi.

nal seat-plank H, arranged over the apron,-

as shown. I I are flat springs, connected at their upper ends with the seat-plank, and at their lower ends with a spring bar or board, J, to which they afford a yielding support. Jlhis rod or bar J has connected to it a number of curved elastic or spring rods or wires, extending from its upper or rear edge upward and over the upper end of the elevating-apron G, as clearly shown in- Fig.- 2, these rods-together with the spring-bar J, serving to hold the grain: properly to the ac,

tion of the elevating-apron 0 To the eppo=-,

and thus serves to facilitate ihc entnrnee: of the grain underneath the springboard. J and sthe yielding rods connected therewith, in a mum' ner that will be readily nnderstondi- To the upper face of the spring-board J is attached the lower ends of straps'-,.chains, or was 3'', the upper ends of which are-connectedwith alifting'roll'er, K, the pivot or shaftof which has its hearin gs in slotted hraclretsh, attached either directly to the seas-plank H, assh'own', or to a longitudinal bar lying paraliiet with said seat-plank, and connected therewith by acentral transverse pivot,- mounted in the seat-plank at or about mid-ways! its length; Where this latter construction is adopted the supporting-brackets L: need not be slotted,- as the vibration of supporting or lifting?- rolien K. is thus: provided: for. The liitin'ag roller; K has a lever, K, rigidly connected wltlr-itso: arranged that the: attesting-by simply vibrating saidleveriuward towardthe roller K in its bearingsya'ntt thus, th'ronghliw connection with the springebeardJ and roller J ,-raise'=the said and bodily For relieving the elevating-apreinfronr my accumulation at grain,v which would! interfere with=itsperfeet action; er,.by vibra-ti'ng'said lever forward or backward; eithe'n omits transverse pivotal connection with the or by raising one: end in: itsislottedpivotal support, as explained, can raise either end of the spring-board independently 05 the other for freeing either end of said board or of the elevator-apron, or rake, from undue accn'mw lation, by permitting it to pass through the enlarged space time provided for its escape.

Upon the seat-plank H, arranged as described, over the elevator-apron, in convenient position to enable the operation of said apron to be observed and controlled by the ing-lever M in an upright, N, on the seat-plank,

the rear end or arm of said lever extending 'intorconvenie'nt position to be-operated by the driver in his seat, and held at any desired point by a notched or spurred segment-rack,

; N, with which the lever is held engaged by a spring. The forward end of the lever is connected. by means of links it n, and lever n, with the pivoted tongue, and through said connection the driver can readily raise the cutters for passing obstructions, or depress them for picking up Fallen grain.

Ordinarily, when the grain is in suitable condition for binding, it is delivered, the long straw to the receiving fingers F, dud the shattered grain and short heads into the receptzr cle F, which also constitutes the bindersplat' form in such case, as already explained; but when the grain has been allowed to become rotted,- or too ripe to safely boundon the mnchii'ie, or it from any other cause it is pre ferred' not to bind it on the machine, I provide for its delivery'into acart or wagon body, arrangedior driven; by this sidvof the machine, by the employment of a; second elevator and urging-apron, 0, which receives it from i elevator: rake tit-spree, 0, after first permitting short and shattered grain to escape between o'ver the'i'n'olined shield E E into the receptacle F. The elevator-apron C is provided with slats having V-shap'edmotches, and the upper end of the deliveryboard E provided with similar notches, both matching hubs,- rings, or forrules don't the intermediitt'e roller D; which,

. being rotated in the same direction with the eiev'atenepron', by any suitable arra ngement of band: and pulleys or" gearing, causes the apron, and discharged-tipped the deliveryboard E The latter operation is facilitated the notched upper edge of the deliverybcsrd forming fingers or projecting spurs e thereon, which-enter the depressions and ef- ,fectualty remme thegraist elevator-apron 6 can rock or: roll: the lifiingpm,- meyapromfiam is connected, by

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. The broad continuous elevator-apron, having its forward edge extended forward or in advance of the platform-apron or carrier, and operating in combination therewith, sub, stantially as described.

2. The roller J, in combination with the yielding spring-board J, substantially as and for the purpose set forth.

3. The compressor for holding the grain down upon the elevator-apron, suspended in position by springs, as described, in combination with a lifting-cord or its equivalent, whereby the driver is enabled, while the machine is in operation, to relieve the pressure of said cover, for permitting the passage of accumulations of grain, substantially as deforth.
