IMPROVEMENT IN GRAIN-Bum.

Specification jbrming'part of Letters Patent N 0. 71,023, dated November 19f1t71 To all whom it may concern Be it known that I, IsRAEL LANCASTER, of Baltimore, in the county of Baltimore and State ofMaryland,'have invented new and useful Improvements on Grain'Binding Machines; and I do hereby declare that the following'is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure 1 is an elevation seen from the front, and showing the operation of the band-carrier 50, and the operation and construction of the wing C, the bar L, and the chain 0. Fig.2 isv an elevation parallel to Fig. 1, and seen from the opposite side, showing the operation of the knife, and also various views showing its construction. Fig. 3 is an elevation, seen from the front, showing the operation and construction of the adjusting lever-B. Fig. 4is a front elevation and partial view from above, showing the construction and operation of the irregular cam and the bar which operates the pinchin g device, and which regulates the friction on the spool from which the band material is drawn. Fig. 5 is a side elevation of the pinching device, seen at right angles to the preceding figures. Fig. 6 is an under-side view of the same. Fig. 7 shows four views of the device for tightening the knot in the sheaf-band.

To assist any one skilled in the art tofully understand and construct these devices, I will say that they are specific improvements upon grain-bindin g machine's secured to me by Letters Patent of the United States, and which machines are fully described in their construc tion and operation in the specifications and drawings making apart of those patents. One

of those patents was issued April 24, 1866, No. 54,177. Another was issued January 23,1866, No. 52,175. An examination of the last-men tioned of these patents will give the information needed to construct these improvements. It will show the position of the platform of the binder in regard to its working parts. It will show the method of actuating the band-carrier 50, Fig. 1, by means of the reciprocating bar A, driven from the cam-shaft. It will show the operation of the sliding block 31, also driven from the cam-shaft. This block is seen in Fig. 2. It has a reciprocating movement from 31 to 31, and actuates the knot-tying device. It shows the construction and operation 1 of the cord-carryin g block 1, Fig. 3, also driven from the cam-shaft 5 also, of the jaw holding the band material and itsoperation, which jaw forms part of this block. It also shows the :operation and construction of the cam-shaft,

identical with 22, Fig. 4, upon'which shaft is placed the irregular cam 23, 24, 25. The cams on this cam-shaft give the initial movements to the entire binder in the proper time, as clearly shown. It also shows the construction and operation of the knot-tying devices. These different parts form no part of this application, but are referred to as explanatory.

I shall now proceed to explain the construction and operation of the improvements forming the subject of this application.

At 0, Fig. 1, is seen a sliding wing, constructed with two side pieces, D D, and the back piece E. D D and E is a section of O on the dotted line E. The back piece E is slightly curved.- This wingO slides on the guide-bar I from (J to C and back. At 50 is seen the band-carrier, composed of two parts,

held open by a spring. The office of this bandcarrier is to place the band round the sheaf. If this is done by allowing the band-carrier to complete its movement from 50 to 50 before the hinged end begins to close on the joint H, the band will be in danger of breaking. The length of cord reaching from the spool Z to the jaw K of the bandcarrier is sufficient to pass round the largest sheaf which can be contained within the embrace of the band-carrier, wing O, and platform of the binder, when the band-carrier is at 50 and the wing G at G, or, in other words, when the sheaf is compressed. When the sheaf is large and the band-carrier has made half its movement, there is no longer cordenough to reach round it in its expanded condition, without the cord itself is sufficiently strong to compress the sheaf partially. This it cannot always do, particularly when the sheaf contains weeds, and the difficulty of breakage occurs. I reinedy this defect by operating the band-carrier and wing 0 simultaneously, 0 passing to C while 50 is passing to 50'. By this arrangement, when the jaw K of 50 is at that part of its passage round the sheaf where the pressure begins to endanger the safety of the band, the part F of the hinged, end of 50 strikes the back piece E of 0 near g, and closes the hinged end of the band-carrier as it passes to the positaching it to an arm fastened to the shaft carryin g 50.

At L is seen a bar standing vertical] This bar travels in the guide on, which is fastened to a stem passing through the back piece E of C. It works on the pivot n at its lower end.

As the wing (J passes to 0, this bar assumes the position seen at L, being carried there by the guide m. The return of U restores it to. its vertical position, seen at L. The object of this bar is to compress any loose or tangled grain which might project above the point k of the bandearrier within the circle described by that point.

At 0 is seen a chain, fastened at one of its ends to the band-carrier at or near thejoint H, and at the other end to the rod 1t, upon which rod is placed the coiled spring One end of this spring rests against a stop, the other against a washer resting againsta pin passing through the rod B. By this arrangement the rod 1% is always thrust in the direction of the arrow, and consequently the chain is always kept strained. This chain rests 011 the end of the shaft carrying the band-"carrier when the hand-carrier approaches the position seen at 50. The tension on the spring p is regulated -to nearly balance the weight of the bandcarrier when it is at the position 50. The object ofthischain,alwayskept strained by thespring 11, is to assist in lifting the band-carrier from and returning it to the position 50, overcoming the inertia in one case and balancing the momentum in the other.

The adjusting-lever is seen at B, Fig.3 This lever is pivoted to a support at one of its ends at The other end is angular and furnished with an eye at 3 through which passes the cord from the spool Z. This lever has. a reciprocating movement from B to B on the pivot 00. The bar a is pivoted to B at one of its ends, and passes through a guiding-support at the other, and is furnished with a pin, T, which projects from the back of a into the slot '11 in the plate 10. This slot actuates the bar ugwhieh in its turn moves the lever B. The plate 20 is fastened to the block 1 at one of its ends, and slides from'w to w on guide-rods. As the pin T passes along the different parts (i 4 3 of the slot 'v, as the plate 10 passes to w or returns, 13 is elevated to B or returned, by means of the bar 20.

The lever 13 performs two duties. At B it places the cord in position to be grasped by one set of pincl'iing-bars 10 5, hereafter described, and atB it places the cord in position to be grasped by the jaws of the cord-carryin g block 1.

At 7,Fig. 2, is shown a side view ot'the knife. At 7 is shown an edge view, both drawn full size. This knife is formed of two cuttingblades,riveted together at their shanks upon a piece one-eighth of an inch thick. The cuttin edge of one of these blades is V-shaped, that of the other straight, and in the direction of a diagonal across the width of the blade, as at 35 35.

At 7 is seen a block through which is passed the guide-bar 32. This guide-bar is rectangular to prevent the block from turnin From thelower side of this block depends a stud, to which is fastened one end of the rod 33. The other end of this rod passes through a guiding-support. Two pins are fastened to the side of this rod, which project laterally,

seen at 34 34. The knife 7 7 is fastened to the block 7, projecting its cutting-end sidewise. The block 7, carrying the knife, has a IQCiPlOOittlllg movement from 7 to 7 on the bar 32, moving the knife on the dotted line 8, Fig. 3, across the stretched cord in that line depending from the set of pinching-bars 10 5 to the jaws of the reciprocating block 1, cutting it onthe line 8. This motion of the knife is given by an arm depending from the block 31. This block has a reciprocating movement from 31 to 31, operating the knot-tying device and completing the closing of the hinged end of the band-carrier on its arrival at 50,Fig. 1. (See former patent.) This arm of the block 31 actuates the block 7 by moving against the pins 34 3 1, shown in Fig. 2.

The action of the knife is peculiar. The cord strikes the edge 35 35 near 35. It may slip against the edge of the other blade 7 36, when the combined action of the two cuttingedges always succeeds in dividing it. VVithout the intervention of the edge 7 36, it would sometimes slide entirely around the end 35, when the edge 35 35 was not very sharp, without being cut.

At 20, Fig. 4, is seen the bar which aetuates the pinching-bars and regulates the tension on the spool Z, which contains the binding material. This bar has a friction-roller, 21, andpin 26 attached to one of its ends, and an inclined projection near the other, shown at 30/ It is held, by supports near each end to its proper position. Near the center of the bar is fastened the plate 16, coutainin g two slots through its thickness. The side of this plate is shown at 16, Fig. 6. This bar has three motions: the first to the right a short distance, the second to the right a greater distance the third to the left over a space equal to the first two distances, and so continuing. These movements are given by the irregular cam-wheel 23 24. 25 on the cam-shaft 22. This cam-shaft,

with the cams upon it, has two movements, one continuous around its axis, and one reciprocating longitudinally. The cams 23 and 24 are plates situated in the same plane. The

cam 25 is in a parallel plane, a short distance from the other, and consists of a projection As the cam refacing the other cam-plate. v volvesin the direction of the arrow, the part 23 strikes the roller 21, and gives the bar its first movement to the right; 24 next strikes the roller and gives the bar its second movement to the right. The shaft 22 now has a movement in the direction of its length, which gears the cam with the pin 26, giving the bar its third movement to the left.

At Z is seen the spool containing the binding material. Against the head of this spool is held the friction-block 27, by means of the coiled spring 28 working on a rod fastened to the block. From this rod projects the pin 29. At the second movement of the bar 20 the inclined part passes under the pin 29, withdrawing the block 27 from the end of the spool. This allows the spool to revolve easily,when the rapid movement of the lever B, Fig. 3, suddenly draws the cord from the spool. Danger of breakage is thus prevented. At the third movement of the bar 20 the head 27 returns to the end of the spool, preventing the unwinding of more cord than is wanted to bind the sheaf.

At Figs. 5 and 6 are seen views of the pinching or cord-holding device. 9 9 is the iron frame holding the different parts. 10 10 is a plate having two projecting parts at its right hand end, which form the upper part of the two sets of pinching-bars. This plate has a pin, 17, which works in one of the slots in the plate 16. 11 11 is a sliding bar passing through the frame 9 9 at one end and having a head at the other. Against each side of this head are placed the two plates 5 5, which form the under jaws of the two sets of pinching-bars. 13 13 are angular supports screwed to the frame 9 and having a slot in each. The pin 12 passes through one end of each of the plates 5 5 and through the head of 11, working in the slots in 13 13 at each end. This pin supports one end of the plates 5 5, and the other ends are supported by a short bar, pivoted to the lower part of the plates at one end, and pivotedat the other end to a support depending from the plate or frame 7. \Vhen the part 11 11 is thrown forward, moving the pin 12 in the slots in 13 to 12, the jaws 5 5 are thrown forward also to the position seen by the dotted lines.

This device is operated as follows: Atthe first movement of the bar 20, Fig. 4, carrying the plate 16, Fig. 6, with it in the direction of the arrow, the pin 17 passes along the inclined part of the slot and throws out the plate 1010 to the-position shown by the dotted lines. The pin 18 travels in the straight part of the slot in which it works in the plate 16, which does not move the bar 11 11. The sheaf-band is now brought against one of the projections of the plate 10 by the arrival of the end K of the band-carrier 50, Fig. 1, to the point K", Fig. 3. It is brought against the other by the lever at B. I The second movement of the bar 20 and plate 16 now takes place,the pin 18 travelin g along the inclined part of the slot, throwing out the jaws 5 5 and "grasping the two ends of the'sheaf-band between 5 5 and 10 10,

as seen at Fig. 3. At" the third, or left-hand movement of 20 and 16,. these pinching-bars are withdrawn. At 15 is seen a stiff spring, always thrusting the plate 16 forward. This is to keep a pressure on the band when the jaws have grasped it, and also to compensate for any wear of parts. At 37, Fig. 6, is seen the device for tightening the knot in the sheafband. This is supported from the frame 9 by the pivot 43. Two side views are seen at 38 and 39, and two end views at 40 and 41, Fig.

7. It consists of a plate with a hook-shaped head and downward-projecting part, against which the shaft of the knot-tying device acts. (Seen at 39.) It is held in its position, (seen at 38) by a coiled spring, 42, attached to its lefthand extremity. It works on the center 43. When the shaft 44 of the knottier is driven in the direction of the arrow against the foot of 37, (seen at 39,) Fig. 7, the head of 37 is brought down until it touches the tube S, round which the knot is formed. The knot is then formed round the head of 37 and the tube S together, just as though the head of 37 was part of the tube. hen 44 and S are with drawn the spring 42 throws 37 to the position, seen at 38, carrying the knot with ;it to a straight line between the pinching-bars. (Seen at 41.) When the sheafis released by the opening of the pinching-bars, the expansion of the straw draws the knot oil of the head of 37. As before stated, neither the shaft 44, the tube S, nor any process of tyin g the knot forms part of this application, what is new being the construction and operation of the plate 37, which carries the knot, after it is formed, from the tube S to a straight line between the pinchingbars, tightening its folds as it does so.

What I claim as of my invention, and desire to secure by Letters-Patent, is the following:

1. The combined action of the band-carrier and wing 0, substantially as described, and for the purpose mentioned.

2. The application to the band-carrier 50 of the chain 0, constructed and operated substantially as, described, and for the purpose mentioned. 1
