SPECIFICATION forming part of Letters Patent No. 592,280, dated October 26, 1897.

Application filed November 23, 1896. Serial No. 613,118. (No model.)

To all whom it may concern:

Be it known that I, HENRY F. CRANDALL, of Milwaukee, in the county of Milwaukee and State of WVisconsin, have invented certain new and useful Improvements in Harve'ster- Elevatorsj and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification and are designed to show my improvements in connectionwiththose parts of an [appropriate harvester, illustra-' tion of which is needed toconvey a proper understanding of a suitable applicationof my invention.

My invention is designed to be "applicableto that class of harvesters by which the grain" is taken from a platform-carrier and elevated and delivered to a binder located upon the stubbleward side of the drive-wheel. Its object is to provide a more positive deliveryof the grain to the binding mechanism, to prevent the accumulation of grain between the upper end of the receiving-deck and the adjacent elevator-roller, and to reduce the height of an elevator-harvester as much as possible.

In the drawings, Figure 1 is a plan View illustrating my invention, the section being from left to right across the delivery end of the elevator-carriers and that portion of the binder-deck reaching across the drive-wheel, the deflector-sheet, the pipe-support for the binder attachment,and a portion of the breast;

plate, showing the manner of connecting the breast-plate to the deflector-sheet and also the connection between the deflector-sheet and the floating'frame. The rollers areshown: broken, also the deflector-sheet, and for the purpose of better illustrating my improvements I-have omitted the canvas apron. Fig.

2 is a sectional elevation somewhat in the nature of a diagram, the section being from right to left through the elevator and the discharge side of the platform-conveyer at one side and the receiving side of the binderdeck at the other side of the driving-wheel, which appears in elevation, the same being shown without grain in the elevator and some elevation similar to Fig. 2 and designed to showthe actionof the grain upon the fioating supplemental carrier, it being shown as forced'upward around its pivotal connection with the elevator-frame, carrying the grainward side of the deflector with it and providing a storage receptacle for the accumulating grain when held back from the binding mechanism by the action of the needle.

1 is the drive-wheel 2, the platform-carrier roller at the discharge side. 3 is the elevator side sheathing; 4, the shifting binder-deck; 5, the upper elevator-apron; 6, the lower elevator-apron; 7 and 7 respectively, the lower and upper rollers of the lower apron; 8 and 8', respectively, the lower and upper rollers of the upper apron. 9 is a supplemental lower roller of the upper apron. 'f It will be understood that the terms upper and lower as applied tothese rollers correspond to the discharge and receiving side as applied to carriers. 1

10 is a fixed deck located above the' d'rivewheel and extends from the grainward side thereof to the movable binder deck upon 'the stubbleward side of the machine.

11 is the needle; 12, the breast-plate; 13,

:the tier-cam; 14 and 15, respectively, the receivingand discharging rollersof thesupplemental transverse conveying-apron;'16, the deflector sheet; 18, thefpip'e support on binder; 17, the supplemental carrier-apron; 19, sliding and pivotal connection between breast-plate 12 and deflector-sheet 16; 20 and 20, short pivotal links connecting the grainward edge of the deflector-sheet to the stubbleward end of the transverse floating frame carrying the supplemental apronand rollers; 21 and 21, swivel journal-box forming bearings for the journals of roller 15 in swinging frame- pieces 22 and 22. These frame-pieces are shown as being made of sheet metal and having the stiffening- pieces 23 and 23, carrying the swivel- boxes 21 and 21, riveted to them, and are pivoted at the receiving-roller journals. This receiving-roller is journaled in any convenient manner (not specifically shown) at the front and rear of the elevator in the same manner as the other rollers and is located nearly in a vertical line above the upper roller of the upper elevator-apron. The upper roller of the upper elevator-apron is located at a point below and grainward of the upper roller of the lower elevator-apron. The upper roller of the lower elevator-apron is located at a point grainward of the drivewheel and at a height to bring the upper part of its periphery a little below the plane of the fixed binder-deck 10. This fixed binder-deck is preferably made of sheet metal and has its grainward side rolled in tube formation, affording required stiffness and presenting a rounded surface to meet the flow of grain and contiguous moving earrier,its lower side overlapping the movable binder-deek 4. and held in position by clips shown at 24, Figs. 2 and 5.

lVith my improvements in operation the grain is received from the platform-carrier by the elevator carrier-aprons, and between them it is carried to a height corresponding with the plane of the fixed binder-deck, and there it meets the action of the supplemental floating or swinging carrier and is positively forced in practically a horizontal plane across the opening between the fixed deck and the upper roller of the lower elevator-apron, and thence across this deck to a point within the compass of the packing and binding mechanism. As the volume of grain increases the supplemental eonveyer is carried upward around its pivot, as shown by dotted lines in Fig. 2, and as it diminishes the conveyor swings down until the slats on the apron come in moving contact with the rounded receiving end of the fixed deck, and I prefer to have it drop low enough to allow the surface of the apron to touch said rounded end when taut and to bend up to allow the slats to pass the edge of the deck. This action effectually prevents any accumulation of grain between the deck and the adjacent elevator-roller, as the action of this floating carrier is as effective with a very small quantity of grain as with a larger, allowing none to accumulate.

In harvesting grain it frequently happens that the butts will be filled with a short growth of grass or weeds and are heavier and bulkier, and the carrier, pressing heavier on this portion, will advance it faster, or, again, other conditions are present and the heads are bulkier and they will get in ad vance of the butts. To meet these conditions,I have made provision for an oscillatory or vibrating movement of my supplemental carrier, as shown in Fig. 1. The de- Hector-sheet is supported by the rod 19, passing freely through an eye at the grainward end of the breast-plate 12, and the grainward edge of the deflector-sheet is pivotally connected by the links 20 and 20 to the rising-and-falling end of the frame-pieces 22 an 22', and the journal-bearings 21 and 21' being free to accommodate themselves to any movement in this respect by reason of their swivel connections with the end of the frame of the supplemental carrier it follows that the delivery end of the floating supplemental carrier is free to swing or vibrate to a limited extent upon its supporting-point, as shown by dotted lines in Fig. 4.

Any of the usual modes of driving the receiving-roller of the supplemental carrier may be employed. I have shown a sprocketwheel 25 attached to the lengthened journaled end, from which flexible connection is made to any of the driving mechanism in some one of the well-known ways.

It is when loose grain is allowed to accu' mulate at the delivery end of the elevatoraprons and lying loosely across the opening between the deck and e1evator-roller that it is drawn down between them. A number of devices have been used in trying to prevent this. All so far have been ineifeetive in preventing the evil, but with my improved supplemental apron, rising and falling with the stream of grain and so arranged as to sweep the last single straw across the opening, the trouble is entirely overcome.

I am aware that I am not the first to use asupplemental conducting-carrier moving in practically a horizontal plane above the delivery end of the elevator-carriers, the same having been in use before; but I have no knowledge of said supplemental conductingcarrier being pivoted above and grainward of the upper roller of the lower elevator-apron, with its stubbleward or delivery roller overhanging the binder-deek and being free to ride and fall or float upon the stream of grain.

Vhat I claim, and desire to secure by Letters Patent, is-

1. In a harvestirig-machine, the combina tion with the elevator and binder, of a vertically-swinging auxiliary carrier, pivotally connected at its grainward end with the elevator-frame and extending therefrom transversely over the upper end of the elevator, and a deflector-sheet pivotally connected with the frame portion of the binder and with the verticallymovable delivery end of the auxiliary carrier, substantially as shown and specified.
