' q i srncrmca'rron formingpart of Letters Patent No. 660,632, dated October so, 1900.

Application filed August 5,1899.

To all whom it may concern:

Be it known that I, THOMAS ELLIOTT, a citizen of the United States, residing at Dallas, in the county of Polk and State of Oregon, have invented a new and useful Band-Cutter and Feeder, of which the following is a specification.

This invention relates to band-cutters and feeders; and the objects in view are to provide means for effectively cutting the bands and properly dividing the sheaf and feed the upper portion considerably faster than the under part, to avoid choking of the cylinder and concave of the thresher, and thereby render the operation of the thresher much more advantageous and thorough, to afford convenient means for changing the speed of the running parts, to accommodate different operations and under varying conditions, and to supply adjustable features to facilitate reduction of the longitudinal dimension of the device and its arrangement over the end of the thresher, to which it'is attachedin folded position. d

Other objects and advantages will appear in the snbjoined description, and the novel features will be set out in the claims, the preferredembodiment of the invention being illustrated in the accompanying drawings, wherein Figure l is a side elevation of the improved band-cutter and feeder shown applied to the end of the thresher in operative position and also folded over in dotted lines to reduce the device to compact form when not in use. Fig. 2 is a top plan view of-the improved band-cutter and feeder. Fig. 3 is a central longitudinal vertical section of the feeder and partfof the thresher as shown arranged in Fig. 1. r Fig. 4 is a detail perspective view of apart of the feeder. Fig. 5 is a detail view, in sectional elevation, of friction mechanism for driving the lower draper and relative parts.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

The numerals 1 and 2 designate contiguously-arranged sections hingedly connected by a transversely-extending pintle or-rod 3,. fitted in coinciding eat-s4 and 5, respectively projecting from the upper terminals of ver- Serial No 726,303- No model.)

tical straps 6 on the inner end of the section 1 and horizontal straps 7 at the upper opposite edges of the section 2. At the outer end of the section 1 is a transverse shaft 8. At the inner lower portion of. the section 2 is a similar shaft 9, and on opposite extremities of the said shafts are small sprocket-wheels 10, .to operatively receive the links of chain belts 11 of a lower draper 12, having slats 13 ex tending transversely thereof at regular inter vals, provided withteeth 14, extending our-- wardly therefrom and curved rearward reversely to the direction of the plane of movement of the said draper to feed the lower part'of said sheaf with a drag or slower than the upper portion. The shafts 8 and 9 are located at opposite end portions of the bot toms 15 and 16, respectively, of theseclions 1v and 2, the shaft 8 being longitudinally adjustable and having movably attached thereto a shifting bottom plate 17, which coujointly acts with the bottom 15 of the section 1 to serve as an extension of the bottom 16 of the section 2 or as an intermediate partition between the opposite portions of the draper 12, which move therearound. The movement of the draper 12 is regular, and that portion thereof which travels above the bottom 15 and 16 and the plate 17 is closer to the latter parts to prevent too great sagging or depression of said portion of the draper and also insure a close feed of the grain to parts which will be presently set forth.

The opposite sides 18 of the section 1, adjacent their rear ends, are formed with longitudinal slots 19, having rear lower bearing-recesses 20 to receive the opposite extremities of the shaft 8 and to hold the shaft down in the recesses. When the parts are arranged in operative relation, pivoted arms 21 are employed and connected to the said sides 18 by pins 22, having eyes 23. On the rear ends of the arms 21 bearing-caps 24 are secured and formed with upwardly projecting curved bearing-seats 25, the lower faces of the said caps having friction-clasps 26, secured at one end thereto. 1 The said keepers are preferably construeted in the form of plate-springs, having their inner ends attached to corresponding ends of the caps 24 and the outer ends extended to provide operating-terminals 27. That part of each clasp which extends across the-bearing seats 25 is similarly struck n p, as at 28, and stands clear of thicsaid seat,

- so asito afford'sufiicient yielding movement to establish a resilient fasteningto hold the said arms 21 down in locked position against accidental disengagement and with suflicient resistance to overcome such-tendency due to the operation of the shaftS. The caps also have a yielding pressure on the oppositeportions of the shaft 8 through the medium of the clasps, and when the arms 21 are down in looking position they cover the slots 19 and prevent the passage of loose grain'outwardl'y therefrom. By having the shaft Sadjustable and movable in the slots 19 the draper 12 can beslacke'ned and the section 1 permit-ted to be thrown up over the section 2 without injury to said draper. When'the shafts is moved inwardly in t-heislots 19,.the-Lplate 17 slides over the upper outer'portion of the bottom 15, and in releasing the said shaft for this adjustment the clasps 26 arefdisconnected by releasing them from frictional pressure and the arms 21 thrown'up, as clearly shown by Fig. 4, to. uncover thev slots 19. The improved device can ,by'the means specifi'edbe reduced to compact form in a convenient lar'band 30. The lower-edge of the guide 29 is located so far above the planeof movement of the teeth 14 of the draper. 12 as not. to interfere with the opera'tion of the latter, and

at its outer end said guide centrally extends to an inclined feed board or plate 31, which also has its lower edge elevated'to clear the draper 12. Theinnerextremitiesof thesides 18 of the section 1 are widened, as at 32, the said increased dimension beginning from the point of locationofthe band ,30 and extending-'to the outer end of the section 2. Ex-

tending transversely across the sectioul and having bearings at its opposite ends in the widened extremities 32 of'the sides I8is'a" shaft 33, located adjacent the band 30 and having fixed thereon at regular distances apart a series of band-cutting disks 34, which are obliquely arranged to effect a shear-cut and are held in regular relation by interposed spacing-sleeves 35, fitted on the sa id'shaft.. One'eud of the shaft 33, is projected beyond;

theadjaceut side of the section 1 and has a band wheel orpulley 36, keyed or otherwise fastened thereon and surrounded by a'belt 37,running from a band wheel or pulley 38, fast on theprojected end of a shaft 39, having'bearing i'n'the upper outer portions o'f'the,

opposite sides 40' of the section 2. I At the inner portions of the said sides of the section 2, in parallel relation to the shaft 39, a shaft 41 has bearing, and on both shafts 39 and 41 7c sprocket-wheels 42 are'keyed and surrounded by chain belts connected to an upper draper or feeding-apron 43, also having cross-slats 44 at-regular-intervals,with teeth 45, curved in the direction of movement of the said draper that poi-flop 'of the-draper-43 which moves 8o thereover, longitudinal guards 46 are secured to the inner faces of the sides 40 of the sec-v tion 2 to permit the chain belts or other devices connected to the draper 43 to be guided and sustained in 'a substantially horizontal plane.

The shaft 41 is extended outwardlyfrom the side of the section 2 oppositeto'that from which the shaft 39 is projected and thereon is secured a cone or double pulley 47, having an outer enlarged band-engaging portion and an inner smaller band-face. The shaft 9 is extended'a't both ends beyond the opposite sides ofthe section 2, and the extended end thereof'nearest theextended end of the shaft 41 also has a cone ordouble pulley 48' thereon, with two belt-faces. the pulley 48 is double the diameter of the similar part of the pulley 47, and a similar proportioncxists'between the inner'parts of said pulleys, the larger dimensions being in the pulley 48. On the opposite extendedend of the shaft 9 is a pulley 49, surrounded by a belt 50, running 'fromlhe driven device 51 on the-thresher to'which the improveddeviee 1 5 is applied. Friction mechanism 52', which will be more fullyhereinafter set forth, is supported adjacent the-pulley 49 and vpartiallylocated on the shaft 9. ,A frame 53 surrounds the extended end of the shaft. 9, no

bearing the pulley 49,, and affords a bearing .for said shaft end. i The friction-mechanismoperat-ing devices are also connected to the frame 53, and the function of said devices is to slow 'up'cr slacken the speed of the shaft.

9 and the draper 12. It will'also be observed that the-speed of rotation of the shaft 41 will be considerably in excess of that of the shaft 9, and consequently the draper 43-will travel.

"ifiu'chfaster than the draper 12, and to i'm5 12o par-t the motion of the pulley 48 to thep'ulley 47 a-crossed belt 54 is used. p

The shaft 9 is intended to be locatedat .a

suitable distance 'from the teeth of the cylinder of the threshing-machineto which the device maybeapplied,andimmediately below thesaid shaft is an inclined feed-chute 55, having a flat bottom adapted to be closely arranged t-othe cylinder and concave of the thresher. The inner-end of the section 2, 13b

which'isdisposed in the thresher adjacent the cylinder and'concave, is also provided with a'hinged hood 56', that drops to aipoint suffici'ently low to shield'the working parts-in the The outer portion of section 2 and overcome any interference of the blast or other air-currents in the thresher with the operation of the draper-s 12 and 43. The hood 56 can be elevated at any time to expose the mechanism in the adjacent part of the section 2 for the purpose of repair or other manipulation. The outer reduced end of the chute 55 is open to serve as an airr feed and is held rigid by a cross-rod 57, secured in opposite hangers 58, and depending from opposite sides of the section 2 are skeleton brace-frames 59, having their inner vertical members, that may be at times rested against the end timbers of the thresher. Rests 60 project outwardly from the frame 59 and contact with the under opposite portions of the inner end of the section 1 when the latter is in operative position. -As a further means of holding the section 1 in horizontal working position legs 61 are secured to the opposite sides 18, about midway of the latter, and have a series of apertures 62 therein to receive the ends of brace-rods 63, movably at tached to the eyes 23 of the pins 22. The function of these legs is well understood, and when the section 1 is folded overon the section 2, as shown by Fig. 1, the braces 63 are disconnected from the legs 61, and the latter are adapted to be turned up against the opposite sides of said section 1 through the medium of a pivotal connection, as at 64. Bindingstraps and other braces will be applied where necessary, and as a convenient means of adjusting the shaft 8 the opposite ends are extended beyond the sides 18 of the section 1.. The shaft 33 for the disk-cutters 34 is preferably square, and the openings through the said cutters and the sleeves 35 are of similar contour, with obvious advantages.

, The bound sheaves are thrown lengthwise on the feed board or plate 31, on opposite sides of the guide 29, and are caught by. the teeth 14 of the slats 13 on the draper 12 and by the movement of the latter fed under the cutters 34, where the bands are severed and the loosened grain spread transversely on the 'said d raper and in this condition carried under the upper draper 43 and thence falls onto the bottom of the chute 55, and subsequently between the cylinder and concave of the thresher. It will be observed that the arrangement of pulleys on the shafts 9 and 11 is to effect a slower action or travel .of the low: draper 12 than the upper draper 43. It has been found that the best results are derived by having the speed of movement of the lower draper only about one-half as fast as the upper draper, and consequently when the grain is brought under the upper draper the more rapid movement of the latter will quickly feed off or separate the upper part of the sheaf from the lower part, and thereby ease the driving power and give the thresher, particularly the separator mechanism thereof, more time to efiectually carry on itswork with much less stress. This operation is facilitated by the direction of the teeth 14, which do not feed with a direct pull on the grain. The obliquity of the cutters 34 will also greatly assist in the operation of the upper draper by dividing the sheaf as it passes thereunder. .By slowing the under draper and increasing the speed of the upper one the upper draper feeds with the same speed. but much less straw, as the under draper moves slower and holds the under part of the sheaf, as previouslyindicated.

The'friction mechanism 52 is composed of a longitudinally-disposed short fixed shaft 64:, held in the opposite ends of the frame 53 close to the extended end of the shaft 9. On

said shaft 64 are loosely mounted friction-' rollers 65, which are located in front and rear of the extended end of the shaft9 and connected to shoes 66 and 67. Movably attached to the shoe 66 is a link 68, and in like manner to the shoe 67 a link 69 is secured. The link 69 isshorter than the link 68, and the shoe 67 is in reverse position to the shoe 66, and both links 68 and 69 are uiov ilolv connected to the shifting-lever 70, pivotal. 'upported on a fulcrum projection 71 from the end of the frame 53 adjacent the separator. The lower end of the shifting-lever 70 is provided with a grip or handle 72, and near the latter is a dog 73, which is located near and in relative position to an arm 74, provided with a series of teeth 75. The pulley 49 is loose on the extended end of the shaft 9 and is maintained in a certain outward position on the said shaft-extremity by a collar 76, which bears against adjacent portions of the side of the frame of the band-cutting and feeding attach ment. On the outer extremity of the extended end of the shaft 9 a frictiondisk 77 is fixed, and the friction-rollers-65 are located between the opposing faces of the said pulley 49 and disk 76, the contact of all of said parts being invariably maintained through the medium of an initial interval arrangement. Itwill be observed that the operation of this friction-disk will be as follows:

Motion from the driving device 51 of the thresher or separator will be transmitted by the belt to the pulley 49 and from the latter through the friction-rollers tothe disk 77 and through the latter to the shaft 9. This arrangement provides for the connection of all irregular movements or fluctua- Lions of the driving element 51, and by shifting the rollers 65 on the shaft 64: the speed may be varied to regulate the movement of the drapers, and to secure a more,positive action of these parts the belt 54 is crossed. If the rollers 65 are simultaneously moved by the devices connected thereto toward the conter of the pulleys 49 and friction-disk 77, the

motion of the shaft 9 will be faster than when the said friction-rollers are nearer the peripheries of said pulley and friction-disk, and an adjustment can thus be obtained having a wide range and to accommodate various kinds of grains fed into the band-cutter and feeder. The shaft 64 has an intermediate bend 78 to efiectively carry out the intended result.

Changes in the proportion, size, and the minor details of construotion'can be resorted toywithout departing from the prineipleor sacrificing any of the advantages of the invention. i
