CHARLES F. HAXVKINS, OF ST. JOHN, KANSAS.

BAND CUTTER AND FEEDER.

S PECIFIGATION forming part of Letters Patent No. 489,679, dated January 10, 1893.

Application filed July 28, 1892. Serial No. 44l1 1- 0 model) To all whom it Huey concern:

Be it known that 1, CHARLES F. Han-Kins, a citizen of the United States, residing at St. John, in the county of Stafford and State of Kansas, have invented a new and useful Band- Outter and Feeder, of which the following is a specification.

This invention relates to band cutters and feeders for thrashing machines; and it has for its object to provide an improved machine of this character which shall secure the re sults aimed for in a more effective and thorough manner than by the use of the ordinary machines for cutting the bands and feeding the grain to the cylinder of the thrasher.

To this end the main and primary object of the invention is to provide band cutting and feeding devices which will not only certainly cut the bands of the bundles and spread the grain, but will also at the same time positively and regularly feed the same at the rate of speed desired.

With these and many other objectsin view which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

In the accompanying drawings;-Figure 1 is a top plan view of a band cutter and feeder constructed in accordance with the present invention. Fig. 2 is a side elevation of the same. Fig. is a vertical longitudinal sectional view thereof. Fig. i is a vertical transverse sectional view on the line an of Fig. 1. Fig. 5 is a detail in perspective of the adjustable knife bar. Fig. 6 is a similar view of one of the vibrating forks.

Referring to the accompanying drawings A represents the fixed feeder frame adapted to be secured to the cylinder end of a thrasher machine into which the grain is fed. Journaled in suitable bearings a at the front or outer sides of said fixed frame is the apron shaft B, which shaft loosely receives the perforated securing arms 0 secured to one end of the sectional apron frame 0. apron frame 0 comprises the aligning sections 0', each having at their meeting ends the perforated hinge and securing plates 0 which when the sections are extended and the table or frame is in use, are connected The said fixedly by the securing bolts 0 one of which may act in the capacity of a hinge or pivot bolt when the other bolt is removed,in order to fold the sections of the apron frame when the same is not in use. Mounted in the extreme outer end of the apron frame is the idle apron shaft D, carrying the opposite sprocket wheels d, over which pass the opposite sprocket chains (Z driven by the sprocket wheels (Z carried by the apron shaft B at the other end of the frame. The said parallel sprocket chains (1' are connected by the cross slats (Z forming an endless apron working over the apron frame to convey or carry the bundles of grain from the extreme outer end of the apron to the inner fixed feeder frame as will be readily apparent. Sockets, E, are secured to opposite sides of the sectional apron frame, and are adapted to receive the projecting arms 6, secured to the side boards 6, adapted to be thus removably secured to the opposite sides of the apron frame so as to hold the grain to its place during its travel over said frame.

The fixed feeder frame A, is provided with the outwardly and upwardly extended bearing arms a, in which are mounted above the inner section of the apron frame 0, the horizontal adjusting rod or shaft F, to which are fixedly secured the bifurcated arms f, adapted to be moved and adjusted with the rod F by means of the adjusting crank or handle f, secured to one end of the rod. The said crank or handle f is adapted to work within the notched bracketf secured to one side of the fixed feeder frame, and providing means for holding the handle in any adjusted position. Pivotally suspended from the outer ends of the rock armsf, are the swinging supporting links f provided with the perforations f, at the lower ends of the same, the lowermost perforations receiving the rounded ends of the adjustable knife bar G, ad j ustably mounted on said lower ends of the swinging links by means of the perforated adjusting segment plates g. The said segment adjusting plates g, are fixedly secured to the upper side of the knife bar G adjacent to the opposite links f, and are adapted to receive the adjustment bolts 9' engaging any one of the series of perforations in said plates and the uppermost perforations at the lower end of said links so that the knives g secured to the underside of said knife bar can be adjusted to any angle desired so as to place the same in the proper cutting position for bound grain and also to set the same in a retarding position for bunches of loose grain so that the knives will act in the capacity of a spreader to level out the bunches. The said knives 9 have sharpened rounded cutting edges 9 which are carried into the grain and across the bands as the same passes thereunder, and the same are swung back and forth or reciprocated by means of the opposite connecting bars 9 The said connecting bars g are loosely connected atone end to the opposite rounded extended ends of the knife bar outside of the swinging links, and at their other ends are loosely connected to the knife operating crank shaft H. The knife operating crank shaft H is mounted upon the fixed feeder frame A in rear of the bearing arms a, thereof, and is provided with the opposite cranks h, which are connected with the ends of said connecting bars so as to swing the knife carrying frame back and forth as the cranks revolve. To one end of the crank shaft H is secured the band wheel H which is driven by a suitable belt from the separator so as to impart motion to the various parts of the feeder, while to the opposite end of said shaft is secured the small chain or sprocket Wheel 7L2, over which passes the endless sprocket chain h which communicates motion to the other parts of the feeder to be presently described, the sprocket wheel end of said crank shaft being extended across and mounted upon the lateral gearing frame a extended from the top and one side of the fixed feeder frame A.

Journaled in suitable bearings upon the top of the fixed feeder frame A in rear of the forward crank shaft H, are the parallel crank shafts I arranged as close as possible to each other and to the cylinder end of the thrashing machine, and each of said crank shafts are provided with a series of cranks i, which are out of line with each other upon their own respective shafts and alternately disposed with relation to the corresponding crank of the other shaft. The said crank shafts are adapted to be revolved in the same direction and the several cranks of each shaft are adapted to carry the feeding forks J, pivotally mounted thereon. The said forks J are provided with upper bifurcated fork arms j, and the lower removable tine heads j. The said tine heads j receive the upper right angularly disposed threaded ends of the depending pointed tines 7' that are adapted to travel over and in close proximity to the flat fioor a within said fixed feeder frame. The upperthreaded ends of said tines are adapted to project through the headsj and the lower ends of the fork arms 7', and receive the clamping nutsfi, engaging the ends, to clamp the tine heads to the fork arms and the forks to the several cranks of said feeding crank shafts, while the tines themselves are held in regular spaced positions by means of the clip bolts j", passing thereover and through said tine heads. The specific construction of feeding forks described are thus pivotally connected, approximately at their centers, to the parallel feeding crank shafts, which as they revolve must necessarily carry the fork tines through a circular movement an d which comb through the grain and evenly spread and distribute it to the cylinderof the thrasher, while the close arrangement of the several forks to each other and to the cylinder of the thrashing machine prevent the cylinder from jerking clumps of wet grain or wet grown sheaves past the same, before they have been combed out by said forks. The several forks are held in position, and a vibratory motion imparted to the same by means of the swinging fork bars K. The said fork bars K are of different lengths, as is necessitated by the position of the two crank shafts I, and are pivotally mounted at one end upon the rock shaft F while their other free ends are pivotally mounted in the upper bifurcated ends of the fork arms so that as the crank shafts I revolve, the several forks revolve toward and away from each other in a circular vibratory movement in order to insure the'even spreading and feeding of the grain to the separator.

In order to prevent the grain passing through the fixed feeder frame A from working up into the cranks of the shafts I, and the tines of the forks and thereby clogging the same, fender bars or strips L are arranged lengthwise of the fixed feeder frame above the table a therein, and are regularly spaced from each other so that the tines of the forks work between the same and are thereby freed from any grain which they may carry upon their upward movement.

The crank shaft I nearest the cylinder end of the thrashing machine is provided with an extended portion 1'', extending across and journaled upon the lateral extension frame a and carries the cog wheels M and M, securely mounted upon the same and of different diameters, the wheel M being of larger diameter than the wheel M. Parallel with the extended shaft portion 'iof the innermost crank shaft 1, and journaled in suitable bearings upon the extension 03, is the counter drive shaft N, upon one end of which is securely keyed the sprocket wheel 0 over which passes the endless sprocket chain h which thereby communicates movement to said counter drive shaft. Loosely mounted upon the drive shaft N are the cogwheels P, and P respectively, the wheel P being smaller than the wheel P and meshing with the larger cog wheel M upon the crank shaft extension 2", while the othercog wheelP meshes with the wheel M, upon said crank shaft extension, which latter wheels are of the same diameter. The cog-wheel P also meshes with an adjacent same sized cog wheel Q, mounted upon one end of the outermost crank shaft I so that both of said crank shafts will IIO be simultaneously revolved in the same direction and always at the same speed, while said cog-wheel P is further provided at one side with a sleeve extension Y carrying at its end the small sprocket wheel R, which in turn drives the endless chain belt S, working over the sprocket wheel T, secured to one end of the apron shaft 13 so as to communicate motion to the endless apron of the feeder frame.

Mounted to slide upon the counter drive shaft N between the cog wheels P and P, is the clutch sleeve U provided with opposite clutch faces to, adapted to be thrown into engagement with either of the clutch faces 13 or 15 1), upon one side of the cog-wheels P and P respectively. The said clutch sleeve U, is mounted upon the counter drive shaft so as revolve therewith and is controlled by means of the bifurcated lever V. The said bifurcated lever V is pivotally mounted upon the bracket 'W, having a notched fiange 20, at one end in which the said lever is designed to be placed in order to hold the clutch into engagement with either of the cog-wheels noted, or out of engagement with both. Now it will be readily seen that when the clutch is out of engagement with both of said cog wheels the knife carrying frame is alone moved which may be done when it is desired to stop the feeder when choking occurs in the separator. But on the other hand as the clutch sleeve, which is driven by said counter drive shaft, is thrown into engagement with either of the different sized cog wheels P and P, the speed of the carrier apron and the movement of the several forks are correspondingly in creased or lessened according to the diameters of said cog wheels, it being obvious that when the wheel P is brought into play, the whole gearing is speeded slower through M, and, vice versa, when the clutch is thrown into engagement with P only, the wheel M is not in use and the speed of the gearing is therefore increased.

The construction of the several parts of the herein described band cutter and feeder has been detailed, and the advantages and operation thereof mapped out, and it is therefore thought that the many advantages of the same will readilysuggest themselves without further description.
