BAND-CUTTER AND SPREADER FOR THRESHlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 573,701, dated December 22, 1896.

Application filed March 26,1896. Serial No. 584,761. (No model.)

To all whom it may concern.-

Be it known that I, MOSES REGNIER, a citizen of the United States, residing at Ghent, in the county of Lyon and State of Minnesota, have invented certain new and useful Improvements in Band-Gutters and Spreaders for Threshing-Machines 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 appertains to make and use the same.

This invention consists of a band-cutter and feeder for threshing-machines, and comprises a certain construction for renderingthe band-cutter automatically adjustable without throwing the driving mechanism therefor out of gear.

It also consists of a spreader forarranging the grain bundles evenly and regularly and feeding the same to the cylinder of the separator.

The objects of the invention are to provide a band-cutter that will automatically adjust itself to large or small grain bundles and a spreader that will arrange the grain to be threshed so that it will be fed to a separator in a regular and uniform manner. To accomplish these objects, the invention consists in the features of construction and the combination and arrangement of parts which will be presently described, reference being made to the accompanying drawings, forming a part of this specification, and in which Figure 1 is a perspective view ofthe machine. Fig. 2 is a bottom plan view. Fig. 3 is detailed view of the spreader. Fig. 4 is a like view of the mechanism for vibrating or operating the same; and Fig. 5 illustrates the manner in which the knife-roll is journaled, so that it will revolve and the boxes be free to move up and down in the slotted brackets.

Like numerals indicate corresponding parts on the different views.

The feeder frame or box 1 is provided with two vertical sides 2 2, arranged parallel with each other, and has the intermediate floor or bottom 3, over which the endless carrier-belt or apron at travels. The belt or apron 4 is of any ordinary or preferred construction, and may be provided with cross-slats, if desired, in a well-known manner in this class of machines. Transverse rollers 6 (j are journaled at each end of the frame or box, and the endless belt or apron 4. travels thereon. Upwardly-projecting brackets 7 7 are secured to the top surfaces of the vertical sides 2 2, and these brackets are provided with segmental slots 8 S, in which slots the boxes 9 9 of the knife-roll are free to move. The brackets 77 are arranged in alinement transversely, one on each side of the frame. The boxes 9 9 have lugs 10 10, which project laterally on each side of the brackets 7 7 outside of the segmental slots, to hold them in position. These boxes may beinserted in the segmental slots, either from the top or bottom of the brackets, in a manner that will be readily apparent.

The boxes have holes 10 through them laterally or transversely, forming bearings for the short journals on the outer ends of the knife-roll. 11 is the knife-roll. It is of any preferred construction, and carries a number of knives or cutters 12, arranged on its pe riphe ry for cutting the bands of the grain bundles or sheaves. The knife-roll 11 has short journals 13, which project through the holes 10' in the boxes 9 9. One of the journals 13 is extended beyond one of the boxes 9 at one side of the frame, and has secured to said extension a band-wheel or pulley 14, for a purpose which will be hereinafter explained. The roller 6 at the front of the machine also extends laterally beyond the sides of the frame or box, and to each end thereof are secured the band-pulleys 15 16. A suitable band connects the pulleys 1 L 15 forrevolvingthe kniferoll. An additional band-pulley is to be arranged on the end of the roller 6 adjacent to pulley 1% to receive aband to be driven from any suitable prime motor. A crank may be used for operating the driving mechanism.

On each side of the frame or box 1 and secured to and depending from the vertical sides 2 2 are brackets or arms 18 18, and extending across underneath the frame and j ournaled in proper bearings in the brackets 18 18 is a shaft or rod 19. At each end of the shaft 19 and on the inside of the brackets 18 18 are rigidly mounted two bevel-wheels 2O 20, which revolve in vertical planes and mesh with two other bevel-wheels 21 21, which are rigidly mounted on two vertical shafts or rods 22 22, which project through the sides 2 2 of the feeder frame or box.

The shaft 19 extends through and beyond the depending bracket on one side of the frame and has rigidly mounted on said extended part of the shaft a band-pulley 16 on the same side of the frame as the band-pulley 16, and the two are connected together by a suitable driving-band, as shown. I

The vertical shafts or rods 22, which carry one member of each of the two bevel-gears, as already stated, project upwardly through the sides 2 2 of the frame and have secured to their upper ends wheels or blocks 23 23, arranged above the frame, and to these blocks 23 the spreader is eccentrically pivoted.

The spreader is mounted in front of the band-cutter and comprises a base or bar 24, which is eccentrically pivoted at its ends to the blocks 23. Ears or lugs 25 25 are provided and arranged a suitable distance apart, and to these ears or lugs is pivoted a cross-bar 26, which forms a part of the frame of the spreader. A proper number of longitudinal bars or arms 27 27 are secured to the crossbar 26 at substantially right angles thereto. The bars 27 have secured to them and depending from the under side thereof series of teeth or spikes 28, and these teeth are preferably set to incline toward the front of the machine, or, in other words, at angles with the under surfaces of the bars or arms 27 less than right angles, although they would operate well if set straight.

I have shown band-pulleys and fiat bands or belts as the driving mechanism, but it will be apparent that grooved pulleys and round bands or belts or sprocket-wheels and chains would produce the same result, and I consider them equivalents.

The operation of the mechanism will be readily seen from a reading of the foregoing specification and the drawings.

Power applied to revolve the band'pulley 15, through the band connecting it with bandpulley 14, revolves the pulley 14 and with it the knife-roll. The bundles of grain are fed as usual and are carried along under the knife-roll, and the latter rises or falls by means of the boxes 9 9 in the segmental slots, so that the knife-roll operates automatically to accommodate large or small bundles of grain. The bands are cut by the revolution of the knife-roll and the grain passes underneath the same to be arranged straight and in a uniform manner to be fed to the cylinder of the separator, which, it will be understood, is arranged at the front end of the cutter and spreader. The spreader is vibrated laterally by means of the band-pulleys 16 16 and their connecting driving band or belt, the power therefor being derived from the retation of the roll-6 through the intervention of the driven pulley 15. The pulley 16 revolves the shaft 19 under the frame, which in turn operates the bevel-gears, rotating the short vertical shafts, and as the spreaderframe is eccentrically mounted vibrates the spreader and arranges the grain in a manner that will be well understood. It will thus be seen that power applied to the driven pulley 15 operates both the cutter and spreader, and the bands are out properlyon the grain-bundles, regardless of their size, without adj nstment or change of the relative position of the parts, and the grain is then properly and regularly fed to the separator.

The arrangement of the knife-roll with the boxes at its ends arranged in the segmental slots in the brackets and the connected driving mechanism is such that no matter What the position of the knife-roll the driving mechanism is not disarranged or thrown out of gear.

Minor changes may be made in details of construction within the scope of the invention without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described the invention, what I claim as new, and desire to secure by Letters Patent, is

1. In aband-cutterand spreader for threshing-machines, an automatically,vertically adj ustable band-cutter, an endless feed-apron, a vibrating spreader arranged in front of the knife-roll, said spreader comprising a horizontal bar eccentrically pivoted, a bar pivoted to the upper side of and parallel with the vibrating bar and rigid arms with depending teeth secured to the pivoted bar substantially at right angles thereto, substantially as set forth.

2. In aband-cutter and spreader for threshing-machines, the combination of a band-cutter, an endless apron, a toothed spreader in front of the band-cutter which is mounted on a transverse bar pivoted eccentrically to the upper ends of two vertical shafts, extending through the frame, bevel-gears on the lower ends of the vertical shafts, and mechanism to rotate the cutter and feed-apron, and 0perate the bevel-gears to vibrate the spreader.

3. 1n a-band-eutter and spreader for threshing-machines a toothed spreader in front of the band-cutter, eccentrically pivoted to the upper ends of short vertical shafts, which extend through the vertical sides of the feedframe, bevel-pinions mounted on the lower ends of said shafts, said pinions meshingwith corresponding bevel-wheels mounted on depending brackets secured to the frame, and suitable driving mechanism.

In testimony whereof I affix my signature in presence of two witnesses.

MOSES REGNIER.
