BINDER.

Specification of Letters Patent.

Patented Dec. 30, 1919.

/ Application filed March 28, 1918. Serial No. 224,745.

To all whom it may concern Be it known that 1, ROBERT HANNA, a subject of the King of Great Britain, and resident of the village of Woodbridge, county of York, Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Binders, of which the following is a specification.

The invention relates to improvements in binders as described in the present specification and illustrated in the accompanying drawings that form a part of the same.

The invention consists essentially of the novel means employed for. straightening the grainprior to its being'knotted.

The objects of theinvention are to eliminate the use of the butter-board, to facilitate the harvesting of grain and generally to produce a binder which will be inexpensive to manufacture, simple of operation and efficient. i

In the drawlngs Figure 1 1s a perspective 7 view of the binder with a portion of the A--A of Fig. a

canvas broken away to disclose the interior construction.

Fig. 2 is a longitudinal sectional view through one of the divided rollers and the gear mechanism mounted thereon.

Fig. 3 is a plan detail view of the roller shown in Fig. 2 showing the operating mechanism connected thereto.

Fig. 4c is a perspective detail of'the divided rollers shown in Fig.2 with the grain guide in position thereon.

Fig. 5 is a sectional view on the line Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings the lower platform 1 is composed of two moving sections 2 and 3 operating over rollers transversely mounted at each end of said platform for transporting the grain to the elevators 4 and 5 for subsequent knotting.

The section 2 located adj acent to the cutter 6 is comparatively narrow and at the end 7 of the platform operates over a roller loosely mounted on a transverse shaft rigidly secured across said end and at the end 8 of said platform operates over'a short. roller 9 which is rigidly mounted on a shaft 10, said shaft 10 being rotatably :mounted at each end in bearings in said frame.

The section 3 is very much greater in width than thesection 2 and fills the remainder of the platform frame, said section 3 at the end 7 of the platform operating over a roller similar to that on which the section 2 operates, both of said rollers being mounted on the same shaft, and at the end 8 of said platform operating over a roller 11 loosely mounted on the shaft 10.

i The rollers 9 and 11 and the corresponding rollers at the other end of the platform are spaced from each other by a longitudinal member 12 mounted at each end on a roller shaft, said member 12 being provided with a raised guide 13 pivotally secured at one end in a longitudinal slot 1 1 and at the other end resting on the shaft 10 for raising the grain slightly at its point of contact with the elevators 4.- and 5.

The member 12 is covered with a sub stantially stifi' piece of material 15 projecting outwardly at each side beneath the edges of the canvas sections 2 and 3 and forming a support therefor.

It is well known that the grain frequently falls to the platform 1 from the cutters in a very uneven state and in order to place 7 all the heads in an even position prior to knotting a butter-board is usually employed but the present invention consisting of a platform having two movable sections so designed as to be operated independently of each other and at different speeds does this work in a more satisfactory manner and at less expense as it is only necessary to rotate one section at a greater speed than that at which the other is traveling to settle the grain evenly on the platform from where it is raised by the elevators for knotting.

The outer end of the roller 11 is provided with a sleeve 16 projecting outwardly therefrom on the shaft 10 and terminating in a sprocket wheel 17, said wheel having its outer side hollowed centrally as at 18, the

edges of said hollow portion being provided with notches 19 at regular intervals therearound.

necessary to show in the drawing said main drivewheel or said connection) and operating over a sprocket 2d mounted on a bracket 25 secured to the binder frame, thence under said Wheel 17 and over the sprockets 26 and 27 which are utilized to operate other parts of the mechanism.

It will be apparent that as the wheel 17 is rotated the pawls 21 of the collar 20 which is rigidly secured to the shaft 10 will engage the notches 19 of said wheel and cause both the rollers 9 and 11 to 1'0- tate-at a like speed.

To facilitate the operation of the narrow section 2 at a greater speed than the section '3 in order to even the grain on the platform a sprocket wheel 28 is loosely mounted on the outer end of the shaft 10 and 15 provided wlth a pro]ect1ng portion 29 notched as at 30 to register with an oppositely disposed notch in the collar 20, said wheel being driven by a chain 31 operating there around and extending over a comparatively large sprocket wheel 32 which in turn is driven forwardly by a cog wheel 83 on the hub of thesprocket 24 coacting with a cog wheel 34; on the hub of said wheel The sprocket wheel 32 being of greater circumference than the various sprocket wheels will operate the comparatively small sprocket 28 at a much greater speed than that at which the wheel 17 travels and when the said sprocket 28 is pushed inwardly into notched engagement with the collar 20, said collar 20 and shaft 10 are rotated at much greater speed than the Wheel 17 which operates the platform 3 thus operating the section 2 at a greater speed than said section 3 and causingthe outer ends of the grain to be drawn up even with the heads which rest on the slower moving section 3.

35 is a lever secured to the outer side of the sprocket 28 and loosely encircling the shaft 10 and being pivotally secured intermediate of its length to a bracket 86 from the binder frame and terminating adjacent to the seat 37, said lever being for the purpose of pushing the sprocket 28 into or out of engagement with the collar 20 as desired.

WVhat I claim is 1. In a binder, in combination, a frame, a main moving platform operating at one end over a roller mounted on a transverse shaft rigidly mounted in said frame and at its other end operating over a roller loosely mounted on a driven shaft, an auxiliary moving platform operating at one end over a roller on said rigid shaft and at its other end operating over a roller fixedlymounted on said driven shaft, a sprocket wheel mounted on the outer end of said loosely mounted roller and being interiorly notched, a ratchet mechanismrigid with said driven shaft and upon the rotation of said loosely mounted roller in a forward direction engaging said notches to operate said auxiliary platform, a drive mechanism operating over said sprocket wheel and an ear iliary drive mechanism loosely mounted on said driven shaft and adapted to be put into engagement with said ratchet mechanism for increasing the speed of said auxiliary platform.

2. In a binder, in combination, a frame, a main moving platform operating at one end over a roller mounted on a transverse shaft rigidly mounted in said frame and at its other end operating over a roller loosely mounted on a driven shaft, an auxiliary moving platform operating at one end over a roller on said rigid shaft and at'its other end operating over a roller fixedly mounted on said driven shaft, a sprocket wheel mounted on the outer end of said loosely mounted roller and being interiorly notched, a ratchet mechanism rigid with said driven shaft and upon the rotation of said'loosely mounted roller in a forward direction engaging said notches to operate said auxiliary platform, a drive mechanism operat ing over said sprocket, a sprocket wheel loosely mounted on the outer end of id driven shaft and having a slotted proj ecticn extending inwardly from the hub thereof adapted to be engaged by a projection from said ratchet mechanism and a chain operat ing over the last mentioned sprocket wheel and over an enlarged driven gear for retating said auxiliary platform at increased speed.

Signed at Toronto, Ont, this 19th day of December, 1917.
