BUNDLE-CARRIER FOR GRAIN-BINDERS.

Specification of Letters Patent.

Patented Sept. 2, 1919.

Application filed June 20, 1918. Serial N o. 241,020.

T0 all whom t may concern.'

Be it known that we, LEVI L. Hmzim and JOI-IN H. WILL, citizens of the United States, residing at Nichols, in the county of Muscatine and State of Iowa, have invented certain new and useful Improvements in Bundle-Carriers for Grain-Binders; and we do 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 appertains to make and use the Same.

Our invention relates to improvements in hai esting machines, and more particularly to bundle carriers for binders, one object being to provide a simple and inexpensive attachment which will carry not only the bundles but any' untied grain to the windrow.

Another object is to provide a bundle carrier which remains in horizontal position while dumping, thus eliminating all danger of injury by dragging along the ground.

A still'further object is to provide a carrier which is reducible in size for traveling' through gates, between trees, along narrow lanes, etc.

Yet another object is to so vconstruct the device as to render it applicable to practically all makes of binders.

With the foregoingobjects in view, the

. the numeral 1 designates as a whole a main frame adapted to be secured to the binder and to extend horizontally therefrom below the deck upon which the bundles are tied and from which they are dropped. Frame 1 is formed of inner and outer auxiliary frames 2 and 3 respectively having a novel connection whereby they may be relatively moved to decrease the amount which the carrier projects from the binder.

Frame 2 consists of side bars 4l, an yinner end bar 5 and an outer end bar 6, said side bars projecting inwardly beyond the bar 5 as seen at 7 and having their inner ends twisted at 8 to cooperate withV clamping plates 9 and bolts 10 in securing the attachment to a suitable art of the binder frame. The projecting enc s of the side bars 4c are provided with suitable braces 11, and in addition to these braces, the frame will be braced directly to the binder frame, but since the manner of bracing depends entirely upon the style of binder used, the additional braces in question have been eliminated from the drawings, A diagonal brace bar 12 extends from one corner to the other of the frame 2 and is rigidly secured thereto at its ends, said bar serving not only to prevent parallelogrammatic movement of the frame, but acting also to support a sheet metal frame covering 13 against sagging, said covering being secured to the side and end bars of the frame 2.

- The side bars A project slightly beyond the end bars 6 and are provided in their upper edges with notches 14, said side bars being also provided, at points spaced inwardly from said notches, with outwardly extending studs 15. These notches and studs coac't with similar features of the frame 3 in connecting the two frames 2 and 3 together.

Frame 3 comprises side bars 16, an inner end bar 17, an outer end bar 18, and a diagonal brace bar 19 similar to the bar 12 and performing the same function in connection with the frame 3 and the metal covering 2O thereof. The inner ends of the side bars 16 project beyond the end bar 17 and are offset outwardly at 21 so that they lie aga-inst the outer sides of the bars 4, said projecting ends being provided with inwardly extending studs 22 received in the notches 14C and with notches 23 in their upper edges receiving the studs 15. By this arrangement, itwill be obvious that the outer auxiliary frame 3 may be swung upwardly upon the studs 22 as pivots, or may be entirely separated from frame 2.

A 'roller 24 or other preferred conveyer guiding means is provided at the outer end of frame 3,.being preferably supported between the projecting ends of the side bars 16, and -a pair of endless chains 26 pass around the roller, and around the sprocket wheels 27 on a drive shaft 28 suitably mounted upon the inner end of frame 2. One reach of each chain 26 passes over the frame l, and the other reach passes thereunder as shown clearly in Fig. 2, and said chains are connected by an appropriate number ofl slats 29 which form therewith an endless conveyer which is normally idle, but which, when driven, serves to discharge the grain deposited onto the. frame coverings 13 and 2O from the binder deck.

At 30, one end of the drive shaft 28 projects laterally from the frame 2, the free end of said projecting portion being` supported at 31 on a bracket 32 which extends laterally from said frame in parallel relation to the shaft. .A clutch member 33 is adjustably secured by a set screw 34 to the projecting portion of shaft 28 for coaction with a simip lar clutch member 35 on one end of a sleeve 36 which is slidable freely as well as rotatable upon the shaft 28 between the clutch member 33 and the bearing means 31. By means of a sprocket wheel 37, sprocket chain 38, and an additional sprocket 39 driven by a rotating shaft '40 of the binder, the sleeve 36 is constantly rotated, and it will thus be seen that when the two clutch members 35 and 33 are thrown into engag ment, the shaft 28 will be rotated to so operate the endless conveyer as to discharge the collected load from the bundle carrier. The -sprocket 39 is secured tothe bindeiin the most convenient place, but in order to 'aline the sprocket wheel 37 with said wheel 39, it is necessary to adjust sleeve 36 and the clutch member 33 along the shaft, and for making further adjustment, said sprocket 37 is preferably secured to the sleeve by a set screw 40, so that it may be shifted along said sleeve as required. When such adjustments are made, it is necessary also that the shifting means of the sleeve 36 be correspondingly adjusted. Consequently, this shifting means is mounted in a novel manner and is preferably constructed as follows:

A forked bell crank lever 41 is fulcrumed to a support 42 Iand the two arms of said fork are provided with rollers or the like 43 which straddle a disk 44 integral with one end of sleeve 36, said bell crank being normally retained in position to retract the clutch member 35, by means of a coil spring 45 -attached at one end to said lever `and at its other end to the outer end of bracket 32.

When lever 41 is rocked against the tension of the spring, however, the sleeve 36 is so shifted as to interengage the two clutch members 35 and 33 to drive the conveyer.

Any preferred means could be employed for operating the lever 41 from the drivers seat, but by preference we lextend alink- 48 from said lever to a bell crank 49 fulcrumed to a suitable part of the binder frame. A link 50 extends from the bell crank 49 to a crankarm 51 on a short rock shaft 52, and a foot pedal 53 is provided for turning said shaft as required. A suitable combined bracket and clamp 54 is by preference employed for mounting shaft 52 on the binder frame within easyreach of the operator.

In operation, the binder discharges the bundles of grain onto the platform formed by the frame coverings 13 and 20, the conveyer normally standing idle, and it may here be also stated that any untied grain is also deposited onto .and carried by the binder, rather than discharging it on the ground as now occurs, due to the spaced rod construction of the usual bundle carrier. When the windrow. is reached, the pedal 53 is depressed, thus throwing the clutch member 35 into engagement with themember 33 and rotating the shaft 28 with the result that the endless chain conveyer is operated to discharge the grain from the carrier. Falling of the grain from the end of the frame 1 is normally preventediby .a gate bar 55 carried by arms 56 which are pivoted to the projecting ends 25 of frame 3, said arms being normally positioned to hold bar 55 in operative position, by means of coiled pull springs 57. 4 When the conveyer. operates to discharge the load, these springs stretch sufficiently to permi-t depression of ,with the accompanying drawing, .itv will be Vobvious that although our invention is of comparatively simple and inexpensive nature, it willl be highly eilicient and in every way desirable. Particular emphasis is laid upon the adjustability of the driving means for shaft 28 and the corresponding adjustability of the controlling means of said'driving means. We also attach great importance to the novel connection between the two frames 2 and 3, to the construction of the frames, including the sheet metal frame coverings supported by the diagonal brace bars to prevent sagging, and to the unique construction used for securing the entire attachment to the binder.

Since probably the best results are obtained from the details shown and described, they are preferably followed, but within the Scope of the invention as claimed, considerable latitude is allowed for making such minor changes as occasion may dictate.

We claim: A

1. A bundle carrying attachment for binders comprising an inner horizontal frame and means for securing it to the binder with the side bars of said frame extending laterally from said binder, the outer ends of said side bars having notches in their upper edges and outwardly extending studs spaced inwardly from said notches, and an outer horizontal frame whose side bars project beyond said inner frame and overlap the side bars of the latter, the projecting ends of said side bars having notches in their upper edges removably receiving said studs of the inner frame, and having additional studs projecting inwardly and removably received in the notches of said inner frame; together with a horizontally moving con veyer trained around both frames, and means whereby said conveyer may be driven.

2. A bundle carrying attachment for binders comprising a horizontal frame and means for securing it to the binder, an endless conveyer trained around said frame, a drive shaft for said conveyer extending laterally from said frame, a sprocket for driving salu shaft, said sprocket being adjustable alon said shaft and rotatable thereon, a cluten member movable bodily with said sprocket, a fixed clutch member on and adjustable along said shaft, a lever for shifting said sprocket and its clutch member to engage the latter with said fixed clutch member, a metal bar parallel with said shaft and secured at its inner end to said frame, the outer end of said bar being bent laterally and carrying a bearing for said shaft, said bar having longitudinally spaced openings, a support for the aforesaid lever contacting with said bar and having a stud receivable in any one of said openings to adjust the lever according to the adjustment of the clutch members and sprocket, and a nut threaded on said stud for securing said support in adjusted position.

In testimony we have hereunto set our hands.
