CORNMHARVESTERl SPECIFICATION forming part of Letters Patent No. 745,091, dated November 24, 1903. Application tiled November lO, 1h02. Serial No. 130,678. (No model.)

'l; all L11/wm, it nca/ 7j cm1/007%:

Beit known that I, DAVID BINNS, a citizen of the United States, residing at Oampehase, in the county of Franklin and State of Ohio, l. have invented a certain new and useful l1n provenient in Cornllarvesters, of which the following is a specification.

My invention relates to the improvementof y eorn-harvesters, and has particular relation to the improvement of the construction showny in my former patent, No. 677,927, issued under date of July D, 1901, in which an end-l less carrier adapted to be moved at a slow retardin the movement on the carrier or endless apron of the stalks which are cut during the rapid shock-discharging movement of the carrier; to provide improved yielding means for holding the accumulated stalks or shock in an upright position on the carrier, said improved stalk or shock holder being so arranged and constructed as to afford a desir-l able degree of resistance to the shock, and to produce other improvements the details of which will be more fully pointed out hereinafter. These objects I accomplish in the manner illustrated in the accompanying` drawings, in which- Figure l is a side elevation of my improved Fig. 2 is a plan broken away to show the fast and slow driving mechanism; and Fig. 3 is a detail view in perspective of the stalk supporting and resisting frame.

Similar numerals refer to similar parts throughout the several views.

As in my said former patent, l employ a body-framework comprising suitably formed and connected parallel frame sides l and a bottom frame 2, this framework or body being mounted upon journaled ground-wheels 3 at each side of the machine, one of these groundavheels, as well as the means for contributing motion from the latter to the feeding mechanism,.bein g omitted from Fig. i of tration.

the drawings for the sake of clearness in il1us- The lower side frame bars 2 are eX- tended, as indicated at 2, toward the front of the body of the machine, and between their outer end portions is provided the usual small journaled advance or ground wheel 2b.

As in my said former patent, l also employ suitable forms and constructions of endless carrying-aprons, one of which has been shown at 4, the latter being arranged within the lower portion of the frame, one on each side of the center of the width thereof. The endless apron is carried on transverselyjournaled rollers, such as are indicated at 5, and suitable means, to be hereinafter described, are provided for imparting at the will of the operator a slow or comparatively rapid movement to the traveling aprons,`and although but one of these aprons is indicated in the drawings it will be understood that the second apron is employed, as in my said former patent, in that half of the machine which is broken away in Fig. 2 and that the various `parts and mechanism employed in the half of the machine shown in said figure are duplicated in said remaining half in order that two rows of corn may be operated upon and handled simultaneously.

At the forward end of each of the traveling aprons I provide the usual or desirable forms of cutters, such as are indicated at G in Fig. 2, and extending forwardly and downwardly from the upper portion of each half of the machine are inner and outer converging guideframes 7 and 8, consisting of parallel guideboards '7a and S, within or between which are arranged endless feed-chains 9. These feedchains follow the inclines of the guides and run over sprocket-wheels lO and ll, said feedchains being provided at intervals with outwardly-projecting feeding-iingers4 l0, as shown in Fig. 2. Extending forwardly and inclining downwardly from the lower portion of the main frame oi' the machine beneath each of the guide-frames 8 and E) is a iixed guide-board 12, and beneath each of these guide-boards l2 is arranged longitudinally an endless feed belt or chain 13, which runs over sprocket-wheels carried on short vertical and suitably-journaled shafts le and l5. Rotary IVO motion is communicated to the shafts 14C, and thence to their sprocket-wheels and the chains 13, preferably through a bevel gear-wheel 1G, which meshes with a second bevel-gear 17 at right angles therewith, which is suitably driven from the ground-wheels Each of the shafts 14 at its upper end is connected throughthe medium of a universal joint 18 with the lower end of an upwardly-extending and forwardly-inclined shaft 19, which, passing through the lower member 8 of the guide- I frame 8, carries on its upper end a sprocketwheel, about which passes a driving-chain 20, said driving-chain also passing about a sprocket-wheel carried on a central pin projection 101 of the sprocket-wheel 10. It will be. understood that this chain-operating' construction applies not only to all of the lower feed-chains 13, but to each of the four upper vfeed-chains.

' 'Ihe construction above described is substantially that of my said former patent, and I have therefore avoided describing the same in detail.

In carrying out my present invention I pivotally mount upon the framework on each side of the machine in front of the body and adjacent to one edge of each of the carriers 4 a hook-body 21. Each of these hooks, which has its inner arm 21l curved, as shown in Fig.k

2, has the outer end of its remaining and preferably straight arm 211 connected through the medium of a rearwardly-extending rod 22 with the lower portion of an upwardly-extending lever 23, the latter extending on the outer side of the main framework of the body 1 and having its upper termination in the form of a suitable handle, as shown. The levers 23 have their lower ends connected with a transverse rod 24, which extends across and is j ournaled in the lower framework of the machine. I also journal in the lower framework of the machine a transverse rod 25, the latter preferably being arranged in rear of the rod 24 and having extending upward from each end thereof an arm 26,which rod-arm is connected at a point 23 in front of the same with the frame 2 through the medium of a spring 27. The upper portion of each of the rod-arms 26 is adapted, as shown in the drawings, to project above the main frame of the machine and to be moved in the arc of a circle. (Indicated by the dotted line touching the same in Fig. 1.) Above the side frames of the machine I employ parallel horizontal frame-bars 29, and upon these frame-bars are adapted to be supported the end portions of a removable transverse rod or bar 30, the normal position of theV latter being against the forward sidc's'of the rod-arms 26.

As shown in Fig. 1 of the drawings, the feedchains 9 and 13 are driven from a drive-shaft 31, and the latter, as indicated in Fig. 2, is in turn driven from the supporting-axle of the machine by means of a sprocket-chain 33, disposed between the wheel 3 and the adjacent side of the main frame of themachine.

It has been hereinbefore indicatedth at it is designed to drive the endless carrier 4 at fast Arection.

and slow rates of speed and to accomplish this result the middle portion of the driveshaft 31 has been provided with a gear 34 and a sprocket-wheel 35, which are loose upon the shaft and have their inner hub portions eX- tended and formed into clutch members 36 and 37, respectively. Between the gear and the Sprocket is a clutch member 38, which is splined or otherwise secured upon the driveshaft to rotate simultaneously therewith and capable of sliding longitudinally thereon. AFor the convenient manipulation of the movable clutch member alternately into and out of engagement with respect to the gear 34 and sprocket 35 a lever` 39 has been provided, with its rear end swiveled upon the movable clutch member and its intermediate portion fulcrumed upon a suitable cross-bar 40, which is supported upon the center sills 2 of the main frame of the machine. The gear 34 is in mesh with a larger gear 41 in rear of the drive-shaft 31 and carried bya counter-shaft 42, j ournaled upon the center sills 2. Upon the countershaft 42 is a sprocket 43, over which runs a sprocket-chain 44, that also runs over a sprocket 45 upon the rear roller or shaft 5, which drives the endless conveyer 4. Another endless sprocket chain 46 runs over the sprocket 35 on the drive-shaft 3l and` also over a sprocket 47 upon the rear roller or shaft 5, this drive chain being intermediately twisted or crossed in order that both drivechains may turn the shaft or roller 5 in the same direction, and consequently always drive the conveyer in oneand the same di- Normally the movable clutch member 3S is in engagement with the gear 34, thereby to drive the conveyer at a normally slow rate of speed. When it is desired to drive the conveyer at agreater rate of speed, the movable clutch member 33 is shifted into engagement with the sprocket 37, whereby the .con-

veyer may be conveniently driven at different rates of speed.

As prescribed in my said former patent the machine is so driven as to cause the cornstalks to be embraced between the pairs of cutting-frames 7 and 3, the movement of the machine against the cornstalks resulting in a cutting contact of the blades 6 with said stalks and in the carrying of the latter in substan- 27, however, it is obvious that the movement of the rod 30 toward the rear end will be comparatively slow and that said rod will serve to retain the stalks in a substantially upright position until a suflicient'number have accu- IZO mulated upon the carrier to permit of their being bound into shock form, this being accomplished after a temporary stoppage of the machine. The shock having been bound, the rod 30 may be removed temporarily, the rodarms again moved toward the front of the machine, and the rod again placed in front of said arms. The machine is now moved forward and a comparatively rapid motion imparted to the carrier i, which will result in the shock being quickly set off on to the ground at the rear of the machine. The shock being .thus discharged, a comparatively slow motion is again imparted to the carrier. lt is obvious, however, that during the comparatively rap id movement of the carrier and ihe forward movement of the machine certain numbers of the stalks will be cut and moved onto the carrier at the front thereof, and in order to prevent the stalks cut during this rapid operation of the machine from being moved tothe rear on the carrier at an undesirable speed l have provided the hooklever 2l, which at the beginning of the rapid movement of the carrier is by moving the lever 23 thrown with its curved arm 2ln over the forward portion of the carrier and into position to receive and retard the motion of the newly-cut stalks, this position of said hook-lever being shown in dotted lines in Fig. 2 of the drawings. When the comparatively7 slow motion is again imparted to the carrier, it is obvious that the hook-lever may by a proper movement of the lever 23 be again thrown outward and the stalks in front of the same permitted to move to the rear at the usual speed.

The advantage of a horizontally-swinging arcuate cut-off lever will here be apparent, as it is obvious that such a lever will swing in behind the stalks without interference thereby or damage thereto, and in the event of the stalks lying in the path of the lever the latter will work its way endwise in between the stalks without damage thereto and without being stopped by the stalks until it has reached its operative position. Furthermore, the arm 2ln of the lever extends rearwardly from the fulcrum thereof in order that it may swing in behind the stalks instead of in front thereof.

From the construction and operation described it will not only be seen that improved means are provided for receiving and holding the stalks in position for binding in shock form, but that improved means are provided for retardin g the rearward movement of the stalks which have been cut during the rapid discharging movement of the carriers.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is- 1 l.
