siding at Canton, in Stark county, in the State of Ohio, have invented new and useful Improvements in Carriers for Fodder-Cutters and Threshing-Machines, of which the following This invention relates to carriers for thrashing-maehines, straw or fodder cutters, 92"Sl1llilar machines; and it has for its objects to pro vide such a carrier in which the frame of the carrier may be hinged at the same point at which the lower or inner shaft is journaled without strain upon the said shaft, in which the parts of the turn-table may be simply and strongly cast in as few pieces as possible, and

' in which the slack of the chains 01' the carrier may be conveniently and independcntlytaken -eiroular flanged boxes, 1 and 2, having the edges of their respective flanges 3 and A bearing against each other and forming a closed box in shape similar to a cheese-box. The flanges of both boxes and the bottom of the lower box are preferablyperforated or formed in open casting, so as to admit of the interior of the box-shaped turntable being cl aned,

and the lower box is secured in any suitable manner under the (.iischargc end of the machine with which it is connected. 'ihe lower box is formed with a central short shaft, 5,

upon the upper end of which the upper box turns with a central bearing, /and the bottom of the box has two bearings, 7, cast integral with it'in. a line with each other, forming mar ings for a radial shaft, 8, which is prm .dcd at its outer end with a geanwhccl, .9, to which the power driving the carrier is appliml, and having at its inner end a beveled pinion, l0,

meshing with a bevelcrown, 11, upon the on der side of a wheel, 12, having a downwardlyextending sleeve, 13, and journalcd upon the ,central shaft of the box, and provided with an upwardly-facing bevel-crown, ii, the sleeve supporting the wheel at the proper height above the bottom of the box. The upper box is formed with downwardly-prqiecting lips 15 to keep the boxes turning against each other with the edges of the flanges bearing true against each other, and the under side of the top of this box is provided with two bearingblocks, 16, in a line with each other, which blocks form bearings for a radial shaft, 17, having abcvel-pinion, 1S, npoirits inner end, n1eshing with the bevel-crown upon the upper face of the central wheel, and having a sprocket-wheel, 19, upon its outer end.

The upper side of the top of the upper box is provided with two diametrically-opposite pillow blocks or posts, 20, immediately at the periphery of the top, and the upper ends of these blocks or posts are formed with open bearings 21, having suitable removable pins, 23, for closing the upper open sides.

Two trunnions, 22, formed with axial bearings 21, and projecting laterally from two cast ings or brackets, 25, upon the inner or lower ends of the side pieces, 26, of the carrier 27, are journaled to rock in the bearings of the blocks .or posts, being confined by the pins, and the carrier-frame may be raised orlowered, rocking with its trunnions in the bearings by forations 30 in the upper portions, with which pcri'rn'ations they are pivoted upon two laterally-projccting studs,3l,npon the side pieces of the frame, the elevation or inclination of the frame being :nljnstedv by adjusting the studs in perforations higher up or lower down in the legs, and by :fhzuiging the angles of the legs. A. shaft, 32, is jeurnaled in the bearings formed in the trunnions, and the outer end of this shaft is provided with asproclget-wheel,33, over which passes an endless sprocket-chain, Ii i, passing under the s 'n'ocket-wheel upon the radial shaft in the bearings under the top of the hex. Endless carrier chains 35 pass aroundsprocket-wheels3o upon this shaft and over sprocketwhcels 87 upon a shaft, 38, at

upon the inner side of its flange, which help means of two legs or props, 2:), having per-.

the upper or onterend of the frame, and transverse slats 39 have their ends secured to these chains and travel up over the bottom 40 of the carrier-frame, carrying the hay, chaff, fodder,

straw, or whatever the machine is to convey,

' in the said extended ends, and the outer sides of the castings are formed with flanges 43 at the sides or edges of the slots, projecting outward and extending at the upper edges of the slots the entire length of the castings, forming ways upon the faces of the same. The ends of the upper or outer sprocket-shaft, 3 8, are journaled in the outer ends of two blocks, 44, in bearings 45 in the same, and the under sides of the rear portions of these blocks are formed with cogged racks 4h. The blocks slide in the slots, having flanges 47 hearing against the inner sides of the slotted castings, and the racks of the blocks mesh with the upper cogged portions, 48, of two wheels,49,having outwardly-projecti ng nuts or heads 50 upon their faces, by means of which they may be revolved, and journaled with inwardly-projecting short shafts 51 in downwardly-projecting extensions 52 in the castings. The lower portions of theperipheries of these wheels are provided with ratchet-teeth 53, which are engaged by weighted pawls 51, pivoted upon the extensions.

It will be seen that by turning the wheels the chain belts of the carrier may be tightened or slaekened, and the weighted pawls engaging the ratchet'teeth will hold the'wheels in their adjusted positions; and having the cogs and the ratchet-teeth upon thesame wheel, but upon different portions of their peripheries, simplifies their construction without interfering with their effectiveness.

The flanges of the upper and lower boxes of the-turn-table maybe provided with hooks or catches 55, engaging eyes or catches 56, so that the boxes may be secured at any desired point of revolution of the upper box and its elevator-frame and be held together without any danger of the bevel-gearing lifting the upper box and slipping cogs, which would be liable liable to do when the frame is pivoted upon the ends of the shaft, as is commonly done in this class of elevators.

It will be seen that the turn-table consists simply of two pieces, all the bearings and the pillow blocks ohposts for the carrier-framebeiug east in one with the boxes of the turn-. table.

The provision of the open hearings in both pillow-blocks allows the carrier-shaft to be set within its bearings and removed at once, for convenience in packing and in transporting the machine. The turn-table box-sections can be separated and put together at once.

Having thus described my invention,I claim and desire to secure by Letters Patent of the United States 1. The combination,in an endless carrier for fodder-cutters and the like, ofa turn tahleconsisting of two circular box-sections, the lower one having a vertical central shaft, 5, and the bearing-blocks 7 7, and the upper box-section having on the lower edge projecting lips 15, the bearing-blocks 16 16, and a. central guidebearing, 6, for the vertical shaft, with the double beveled cog wheel adapted to turn freely upon said shaft, the driveshaft S, journaled in the'bearings of thelowcr box-section, having a bevel-pinion, 10, upon its inner end, meshing with the lower crown, 11., of the central wheel,and having the drive-gear 9,-a shaft, 17, journaled in the bearings of the upper boxseetion, having a bevel-pinion, 18, upon itsinner end meshing with the upper crown, 14, of the central gear, and acarrier-frame j ournaled upon the upper box-section, and having an endless carrier connected by gearing to and driven from the upper boxshaft, as shown and described.
