SPECIFICATION forming part of Letters Patent No. 624,024, dated May 2, 1899.

Application filed April 17, 1897. Renewed April 7,1899- Serial No. 712,158. (No modeLl To all, whom it may coneerm Be itknown that I, AUGUST J. HEINE, a citizen of the United States, residingat \Vahpeton, in the county of Richland and State of North Dakota, have invented a new and useful Band-Cutter and Feeder, of which the following is a specification.

The presentinvention aims to improve the general construction of band-cutting, feeding, and spreading attachments for threshing-machines and to obviate choking of the thresher when the grain is damp and facilitate the work and admit of access being readily had to the Working parts for any desired purpose.

A further purpose of the improvement is to combine the parts in such a manner as to admit of their folding into a small compass, whereby the dimensions of the machine may be materially reduced for any purpose required, and in this connection the parts are so related as to admit of inspection and access thereto for cleaning and repairing.

A still further purpose of the invention is to improve the general construction, whereby the efficiency of the attachment is materially increased, convenience and ease of handling attained, and the parts capable of being readily folded and placed in position for use when required.

For a full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description.

The improvement is susceptible of various changes in the form, proportion,and the minor details of construction without departing from the principle or sacrificing any of the advantages thereof, and to a full disclosure of the inveniion an adaptation thereof is shown in the accompanying drawings, in which- Figure is a side elevation of the improved band-cutting, feeding, and spreading attachment, showing it in operative relation. Fig. 2 is aview similar to Fig. 1, showing the parts folded. Fig. 3 is a view in elevation of the attachment as seen from the remote side of Fig. 1.

Fig. 14.- is a section on the line Y Y of Fig. 1. Fig. 15 is a detail view showing the hinge connection between an extension-wing and a side of the carrierframe.

Corresponding and like parts are referred to in the following description and indicated in the several views of the accompanying drawings by the same reference characters.

The separator or thresher, which may be of any of the usual forms, is indicated by the numeral 1, 2 representing the threshing-cylinder and 3 the concave or breast. The attachment is secured to the receiving end thereof and comprises side pieces 4., to which the operating parts are attached. An endless grain-belt 5 is supported upon rollers at the ends of a frame 6, having pivotal connection at its outer or front end with the forward ends of the side pieces 4, the inner or rear end of the grain-belt and its supporting-frame being free to move vertically or drop, so as to admit of access being readily had to the threshing mechanism. A plate 7 has pendent lugs at each end, in which is slidingly mounted a bolt 8, which is held projected by a spring 9, mounted upon the inner end of the bolt and confined between the inner lug and the fingerpiece, by means of Which the bolt is withdrawn when it is required to remove the plate to permit the inner end of the frame 6 and grainbelt to drop. A bracket 10, secured to the inner end of the frame 6, rests upon the plate 7 and supports the grain-belt a proper distance therefrom. slot 11, formed in the side-pieces 4, and a spring 12, secured at one end to each side 'piece, exerts a pressure upon the projecting Each bolt 8 operates in a end of the bolt 8, so as to retain the plate 7 in position. The shaft 13, supporting the out-er roller of the grain-belt and having the frame 6 pivotally mounted thereon, is journaled in the side pieces 4 and is provided at its ends with a pinion 14 and a sprocket-wheel 15, the pinion 14 meshing with a gear-wheel 16, secured to or formed with a speed-pulley 17, which is driven by means of a belt 18 from a pulley 19, secured to the projecting end of the shaft bearing the threshing-cylinder 2.

Bars 20 have pivotal connection at their rear ends with the side pieces 4 and are connected near their front ends by a cross-bar 21 and support a shaf 22, carrying star-cutters 23, which operate in spaces formed between guards 24, secured at their front ends to the crossbar 21. The guards 24 are spring-plates about equal in width to the distance between the star-cutters and spaced apart a proper distance to admit of the star-cutters working freely when the attachment is in operation. The guards or spring-plates 24 support the grain in its passage from the carrier 25 to the thresher or separator and prevent the winding of the same about the shaft22. The outer ends of the bars 20 are cut away, as shown at 26, forming a projection 2", over which extends a bearing 28, secured to the framework 29 of the carrier 25, whereby the front ends of the bars 20 are held upon the top edges of the side pieces 4 when the attachment is adjusted to a working position. A pinion 30 is secured to one end of the shaft 22 and meshes with a gear-wheel 31 on the end of a shaft 32, havingthespeed-cone17seeuredthercto. By this means the cutting mechanism is driven. The carrier is of ordinary construction and comprises an endless apron and a framework, the side pieces 29 of which are extended beyond the inner end of the endless apron to form a support for the spreading mechanism, consisting of a toothed shaft protected by guards 34, supported at their ends by crossbars 35, whereby the grain is prevented from winding around or choking the part and theteeth applied thereto. A gear-wheel36 is secured to a projecting end of the shaft and is driven from a transverse shaft 37 by means of a pinion 38, secured to the shaft 37 and intermeshing idlers 39. The shaft 37 receives the roller, upon which the endless belt of the carrier is supported and driven, and a gearwheel 40 is secured to an end of the shaft 37 and meshes with the gear-wheel 16 and receives motion therefrom. The shaft 37 is mounted in a bearing 28, secured to each side of the carrier-[ramework, and these bearings form trunnions for the carrier 25 to tilt or turn upon when adjusting its outer end to any required elevation. These trnnnions being located a short distance from the inner end of the carrier and the spreader mechanism being supported by the said inner end, it is obvious that a vertical adj ustmentof the outer end of the carrier will effect an adjustment of the spreader mechanism toward and from the cutting mechanism, so as to regulate the distance between them to suit the quantity of grain to be fed to the thresher in a given time. Adjustable supports are located at the outer end of the carrier and consist of

movable sections

41 and 42, which are held in an adjusted position bya clamp-bolt 43. By lengthening and shortening these supports the outer end of the carrier can be moved to the required elevation and the desired distance between the spreading and cutting mechanism socured. \Vhen drawn out to an operative position, the bearings 28 drop into the spaces 26 and are secured by a lock-bolt 44, slidingly mounted in a keeper 45, fastened to an upright 46. This lock-bolt has a lateral extension 47, which is adapted to pass through a notch 48 in the outer member or bent end of the keeper 45, whereby the lock-bolt can be withdrawn from engagement with the bearing 28 or projected across it, as required. \Vhen projected, the lock-bolt is turned so that the pin 47 will engage with the inner side of the outer member or end of the keeper having the notch, thereby holding the bolt locked. A spring 48, mounted upon the lock-bolt, engages with the pin or lateral extension 47 and holds it against the outer member of the keeper, so as to prevent accidental slipping when the parts are adjusted to a working position. A divider49 separates the carrier longitudinallyin the ordinary manner and is supported at its front end by the inner cross-bar 35 and at its rear end by a cross-bar 50, upon which the adjustable supports for the outer end of the carrier are mounted. To prevent the grain falling over the sides of the carrier, wings or extensions 51 are provided and hinged to the side pieces 29, and astrap-iron 52 is secured to the outer side of each wing and has its lower portion bent, as shown at 53, to extend over the top edge of the side 29 and again bent, as at 54, to overlap the outer side of the part 29,whereby the \vingis braced when turned outward to attain the object for which it is provided. A turn-button 55, applied to each side 29, engages with the bent portion 53 of the iron 52 and holds the wing in proper position. The top edge of the sides 29 is notched to receive the

parts

55 and 53, as clearly indicated in the drawings.

The uprights 46 are hinged or pivoted a short distance from their lower ends to the upper outer corners of the side pieces 4 and are connected near their lower ends bya crossrod 56, which is engaged by catches 57, pivoted to the side pieces 4 for holding the uprights in proper position. Upon releasing the cross-rod 56 the uprights 46 can be folded, as indicated in Fig. 2, thereby reducing the height of the attachment. Bars 58 are slidably mounted with respect to the uprights 46 and are held thereto by suitable keepers and. have their lower portion toothed and intermeshing with a pinion 59, secured to a shaft 60, journaled in bearings provided on the uprights 46, said shaft having a crank 61 at one end, by means of which it is'turned so as to raise and lower the bars 58 and the walkingrakes applied thereto. The bars 58 are held at the desired elevation by means of a pin 62, which is thrust between teeth thereof and engages with the top side of a keeper 63, through which the respective bars operate. Abracket 6i is hinged to each bar 58 to the front side thereof, and its spindle-arm supports a roller 65, upon which the carrier is supported when moving toward and from a working position. \Vhen the carrier is drawn out,.each bracket 64 is released and turned so as to throw the roller 65 in front of the bar ,58, thereby admitting of the latter being raised and lowered and the bracket and its roller passing by the carrier. A plate 66 is secured to the inner edge of each bar 58 and forms astop to limit the outward swing of the bracket 64, whereby the roller 65 is held in position to receive the weight of the carrier as may be desired. A pivoted dog 67 is applied to each bar 58, and its outer end is bent to engage with the bracket 64 and hold it open when brought against the stop 66.

A compound crank-shaft 68 is journaled in bearings provided atthe upper ends of the bars 58 and is provided at one end with a sprocket-wheel 69, and the crank portions have blocks 70 journaled thereon and to which the walking-rakes 71 are secured, the upper ends of the rakes slidingly operating in blocks 72, mounted upon a rod 73, supported at its ends in plates 74, secured to the upper ends of the bars 58. The blocks 72 rock upon the rod 73 simultaneously with the sliding movement of the rakes 71 therein. The walking-rakes operate toward thereceiving end of the carrier and serve to regulate the feed of the grain,the latter operation being accomplished by the raising and lowering of the bars 58, whereby the. distance between the endless apron of the carrier and the active ends of the walking-rakes is regulated. A sprocket-idler 75 is located at the lower end of one of the bars 58 and receives asprocketchain 76, which passes over the sprocket wheel 69 and engages with the sprocket-wheel 15, by means of which it is driven, thence over an idler 77, whereby provision is had for the vertical adjustment of the bars 58 and the transmission of power to the walking-rakes.

When the attachment is in the position shown in Figs. 1 and 4c, the operating parts are set in motion by the drive-belt 18, the latter being preserved under tension by a roller 78, carried by a lever 79 and engaging with the lower portion thereof, said lever being held in the required position by a notched bar 80. If it be required to throw the feeding mechanism out of gear, the lever 79 is released, thereby permitting the roller 78 to move away from the drive-belt 18, which latter, becoming slack, no longer transmits motion from the thresher to the operating parts of the attachment. The grain to be threshed tion with the spreader, to separate and loosen the grain prior to its admission into the separator,whereby the threshing operation is greatly facilitated. The cutting mechanism revolves at a higher rate of speed than the spreading mechanism, and the latter serves to retard the forward movement of the grain, thereby preventing choking of the thresher in the event of the grain being damp. Any grain detached from the straw by the cutting and spreading mechanisms is received upon the grain belt 5 and moved forward to the thresher, the plate 7 preventing the wasting of the loose grain and directing it into the separator.

When it is required to reduce the size of the attachment so it will occupy the smallest amount of space, the carrier is released by withdrawing the locking-bolt 44:, after which the bars 20 and the uprights 46 are folded, as shown in Fig. 2, and the carrier is placed thereover, being supported upon rollers 81, provided on the thresher 1. A balance-wheel 22 is applied to the cutter-shaft 22 to cause it to run steady.
