SPECIFICATION l forming part of Letters Patent No. 664,253, dated December 18, 1900.

Application filed July 3, 1897. Serial No. 643,335. ALINO modelo To @ZZ whom it may concern.-

Beit known that we, ANDREW E. GAGNON and HENRY J ONOAS, of Minneapolis, Hennepin county, Minnesota, have invented certain new and useful Improvements in Knotters for Binders, of which the following is a specication.

Our invention relates to machines for binding laths oi' like products in Wood and also to grain-binders and in general to all machines which wind or bind a cord or band about a bundle and tie a knot with the ends of the cord. KThere are many machines of this general class and many which satisfactorily perform the service required in binding grain or like colnpressible stuff which will expand and .fill the loop or encircling band; but up to the present time no successful machine for binding suchincompressible materials as Wood or metal in bars or sticks has been produced to our knowledge.

It is one Object of our invention to prov-ide a binder and knotter which, in addition to tying a very tight knot, will draw the cord or' band firmly around the bundle and leave the cord under tension before the 'material is removed from the compressor, which is used to hold the bundle in form while being bound; and it is a further object of our invention to provide such a positive device which, While specially adapted for binding laths in a bundie Or bundles or any incompressible article, will by its lightness and coinpactness of form be equally adapted for use in binding grain and the like and willshow amarked improvement in that special branch of the art.

The leading and most definite objectof our invention is to provide a knotter which after forming the loop, which may be done in many ways, will hold the ends of the cord and roll or force the untightened knot close up to the bundle and thentighten the knot, placing the cord under tension, and leaving the knot against the bundle so firm and strong that it cannot become untied or loose and open.

Our invention consists inthe combination, with suitable means for passing or wrapping the cordv or band around a bundle, of means for forming a loop in the cord and for drawing the ends .of the cord through the loop to form the untightened knot and a device or part closing upon the cord on that side of the untightened knot opposite the bundle, the drawing and closing means being relativelyy movable to cause the untightened knot to be rolled against the bundle.

Our invention further consists in improved means for tying the knot and for cutting the cord, and, further, our invention consists in particular constructions and combinations of parts, all as hereinafter described, and particularly pointed out in the claims.

The invention will be more readily understood by reference to theaccompanyingdrawings, forming a part of this specification, and

in which- Figure 1 is an end elevation of a knotter embodying our invention. Fig. 2 is a side view thereof .in section on the line .It m of Fig. 1. Fig. 3 is an end section on the line yy of Fig. 2. Fig. 4 is asimilar section on lineman of Fig. 2. Fig. shows the inner face of the moved back and forth intermittently. Fig. 6 is an enlarged longitudinal section of the knotter and knot-drawing mechanism. Fig. 7 is a sectional view of the same on the line y y of Fig. 6. Fig. 8 is a sectional detail on the line z e of Fig. 7. Fig. 9 is a cross-section on the line t i' of Fig. 6. Fig. 10 is a cross-section on the line of Fig. 6. Fig. 11 is a perspective View of the top of the head, showing the plates which close back of the untightened knot. Fig. 12 is a section substantially on the line of Fig. 4 and illustrating the action of the knife. Fig. 13 is an enlarged bottom View of the knife and the knife-case as seen from the line 0cm of Fig. 12. Fig. 14 illustrates the cutting of the cord. Figs. 15, 16, and 17 are sectional and perspective viewsillustratinga modified form of the knotter-hook. Fig. 18 illustrates a device illustrated in Figs. 15, 16, and 17 in position ready to tie the knot. Fig. 19 shows the knot tied, but not tightened against the bundle. Fig. 20 is a sectional view showing the hook drawn in, while the pressureplates hold the untightened knot on the head and force the same against the bundle. Figs. 21, 22, 23, and 24 illustrate four successive positions of the parts from the beginning of the operation to the completion of the vsliding cam by which the knotter-hook is l IOO knot. Figs. 25, 26, 27, and 28illustrate four successive positions of the knotter and head during the process of forming the knot with the mechanisms illustrated in Figs. 6 and 7.

Referring to the drawings and particularly to Figs. 6 to 11 and in connection therewith Figs. 1 and 2,v the machine will be seen to comprise three principal parts-the knotterhead mechanism, the knife mechanism, and the motive shaft, with its cams and gearwheel. The sleeve 2 upon the base-plate 3 serves as a bearing for the hollow shaft 4, having a gear-pinion 5 upon its lower end and containing the slidable head 6, which head in turn contains the slidable stem or rod 7, which has the hook 11 upon its upper end. The rod 7 is prevented from rotating in the head 6 by the hook at its upper end, and the head 6 is prevented from rotating in the hollow shaft 4 by a key S. The head is provided with a recess 9 to admit the heel lO of the hook 1l when it is drawn inward. The head is turned, with the shaft 4, through the medium of the pinion 5 and the gear 12. The gear 12 is secured upon the motive shaft 13, which has suitable bearings 14 and is driven through a gear 15 upon its opposite end. Both the pinion 5 and the gear 12 are mutilated gears, the gear l2 having the same number of .teeth as the pinion 5 and having a liange 16 to engage a iiap or straight shoulder or face 17 upon the pinion and whereby the pinion is held against rotation during the time the gear is completing its revolution. The shoulder 17 is released before the teeth of the two gears again engage. During the time thatl the pinion, and hence the head and hook, is being rotated the stem or rod 7 is longitudinally stationary within the head. This is accomplished by means of a sliding camplate 18, movable between suitable guides 19, extending from the base 3 and having upon its inner face an irregular groove, (see Figs. 1 and 5,) a portion of which groove 20 is semicircular, and a portion 2l thereof is returned in a V form, the groove having inclined sides. 22 is a pin on the face of the gear-wheel 12 and entering the groove 20. While the gear-teeth are in mesh the pin will move in the semicircular portion of the groove, so that the cam-plate, to which the lower end of the hook rod or stem 7 is attached, will not move; but as the gears pass out of the mesh the pin will move into the straight portions of the groove and pull the plate down during one part of the revolution of the gear-wheel l2 and force it back into position during the remaining part of such movement. 23 is a bell-crank having a yoke 24, provided with lugs extending into the groove 25 in the head G. The other arm of the bell-crank engages with the side cam 27 upon the shaft 13, and before the hook is drawn down this cam acts to lift the head, this movement being to tilt the hook and make the cord secure therein by closing the hook parts together before the hook is drawn down into the head. The hook 11 is pivoted upon a pin 28 in the upper end of the rod 7, said upper end being bifurcated to receive the hook. The hook is provided with a heel 10, which is arranged beneath a small crossbar section 29 of the head, there being sufiicient play between said heel and said crossbar section to permit the heel to swing out under said section when the hook is tilted on its pivot and drawn down into the head. Upon the upstroke of the hook after it has passed out of the head the heel engages the cross-bar 29 and tilts the hook down to a horizontal position, as shown in Fig. 6. 30 is a tongue, also pivoted on the pin 28 and adapted to close upon the hook 1l when it is drawn into the head. A spring 3l holds the tongueor finger 30, but allows the same to yield at the time when the knot is drawn off in removing the bundle from the machine. It will be noted that the rod 7 is eccentrically arranged in the head and the sleeve or shaft by which it is rotated. The rod, however, at its lower end is provided with an offset portion 32, journaled in a block 33 on the camplate 18 and concentric with the head. One side of the head is also out away, the object being to form the knot in a position substantially in line with the axis of the head, so that in turning the head, which is a part of the operation, the cord will simply be twisted and the knot will not be swung around or the string sawed on the bundle. This is a pai'- ticular feature of our invention, as in the numerous experiments made with knottersnot so constructed much annoyance was experienced by the breaking of the cords. One side or corner 34 of the head is beveled, so that the string will slide up onto the top of the head easily and from thence into the hook just as the revolution is completed. In the head are two transversely- slidable plates 35 and 36, onevbeing preferably within the other and adapted to close together on that side of the untightened knot opposite the bundle when the hook is drawn down. Their movement is accomplished by means of the short levers 37 entering slots 37' therein, as shown in Fig. 7, and pivoted in the head upon pins 33. The opposite or lower ends of the levers project into grooves 39 in the sides of the hook rod or stem 7. The bottoms of these grooves are parallel for a distance, so that the plates 35 and 36 are held stationary until the hook passes beneath them. The bottoms of the upper parts of the grooves are inclined, so that the final movement of the stem causes the spreading of the lower ends of the levers and the pressing together of the plates 35 and 36 to retain the knot upon the top of the head, instead of drawing it back into the head with the hook, and as the head moves up it rolls or forces the loose or unt-ightened knot against the bundle to be tightened thereon by the hook drawing down the ends of the cord.

A modied and, we think, a better form of knetter-hook is illustrated in Figs. 15 to 20,

IOO

IIO

inclusive. Th'e other parts of the device remain the same. This hook comprises a fixed hook 40 upon the upper' end of the rod 7 and a tilting part comprising two fingers 41 and 42, provided, like the other device, with a heel 10, by which the fingers are swung from one position to the other. The finger 41 is provided with a slot 43 to admit the hook 40, and the finger 42 has an opening 44 to admit the point of the hook, as shown in Fig. 15. When the two strands of the cord have been drawn in between the two fingers, the fingers are tilted and said strands will be bound between the hook 40 and the finger 42, and obviously cannot escape therefrom so long as the hook is drawn down into the shaft-hole in the head.

The knife or cutting mechanism will be best understood by reference to Figs. 3, 4, and 12. The knife guide or case 45 is secured upon the frame 46, which is pivoted upon a fixed shaft or rod 47, secured in the base and parallel with the shaft 13. This frame is automatically swung toward the hook of the knotter by a lever 48, engaged with a crank-pin 49 on the disk 50. The pin is made adjustable by setting it upon an independent adjustable plate 5l. The lever 48 is pivotedion the rod 47, and at its opposite end engages with a lug 52 on vthe knife-frame 46. The frame is held upon the lever byastrong tension-spring 53, which, however, permits the knife-frame to leave the lever in case it is necessary to equalize the strain or tension upon the cord by allowing the frame to yield and draw up toward'the head without being positively moved to such position by the lever. The movement to the positions shown in Fig. 3 by dotted lines is made to bring the knifeinto position to catch the cord from the finger of the binder, and the cord is positively moved into line by means of a small finger 54, pivoted on the stud 55 and connected by a link 56 to the knifeframe, (see Fig. 12,) whereby the movement of the finger is at all times commensurate with that ofthe knifeframe to carry the cord into the notch 58 in the guard or case 45. The deeper portion 59 of this notch is intersected by the knife 60, which is a bar slidable in the case 45 and reciprocated therein by the side cam 61. The end of the knife is beveled or rounded, as shown at 62 in Fig. 14, and the lower shoulder 63 of the notch 59 is also beveled to prevent the cutting of the cord between the bottom of the knife and the case. The upper edge of the knife is sharp, and the cord is cutI between the same and the shoulder 64 of the notch in the upper part of the case or guide. At the moment the cord between the bundle and the binder-arm 65 is moved into the notch 59 by the finger 54 the knife is drawn back by the action of the cam 6l, acting through the sliding frames 66 and 67, which frames or arms are independent to permit the tilting or swinging of the knife-frame. At the next instant, just before the head of the knetter is lifted, the arm 66 in engagement with the cam 6l will drop over the abrupt shoulder 68,

and the knife will be forcibly shot back to cut the string by the spring 69, coiled on the rod 47, said arm 66 being held from turning on the shaft 47 by a pivoted link 66. The free end of the cord, with that before liberated by drawing back the knife, may then be drawn through the loop, while the end of the cord in the binder-arm will be caught and held in the knife-case, as shown in Fig. 14.

The complete operation of our machine will be Well understood by reference to Figs. 21 to 24. The base-plate 3 is secured to the frame 70 of the bundling and binding machine. The machine partially illustrated in Fig. 21 is a lath-binder and is provided with compressorarms 71, (see dotted lin.es,) which compress and form the bundle preparatory to the wrapping of the cord aboutthe end thereof. 72 isa guard-plate and. cord-guide which overhangs the knetter-head, and the needle-arm 65 is provided with a guard-plate 73, which as the arm is carried around beneath the bundle will abut against the edge of the plate 72. The two plates are provided with notches 74, which form a hole in which the vstring is guided and held opposite the knotter-hook and in line with the axis ofthe head. The string or cord 75 is taken from a suitable tension roll or bobbin (not shown) and is threaded in the needle-arm 65 and through the eye therein.

From thence it is carried downward and over the edge of the plate 72 and4 thence past the hook and back to the knife-casing 45,in which it is secured. rlhe bundle or bunch of laths or other articles is then put in place, whereupon the machine is ready to start and will thereafteroperateautomatically. Whenthe machine is started, the needle-arm 65 will swing forward over the top of the bundle and then downward and around beneath the same into the position shown in Figs. 22, 23, and 24. The needle-arm remains in this position until the bundle is tied and removed. The downward movement of the needle-arm forms a loop around the bundle with both ends or strands of the loop caught upon the forward side of the hook. At this time the head 6 receives one complete revolution fromthe gear 12 and in the direction shown by the arrows in Figs. 21 and 22. The ends 77 of the loop are carried up onto the top of the head by the rounded corner thereof when the head is turned and are wrapped about the hook over the two loops which are on the side thereof. The ends of the cord drop into the space between the two fingers of the hook, the knifeframe and the finger 54 having meantime been raised to the position shown in Fig. 23

to carry the strands of the cord into the knotter and prepare the continuous strand thereo f to be severedin the knife. Next follows the operation of the knife, the same being drawn back by the cam 68,and after the string is cut, with a new end left in the knife, the head 6 is raised by the lever 23 to roll the loop or unfinished knot against the bundle,

IOO

thereby tilting the hook and closing the jaws thereof to confine the ends of the cord therein. The ends of the cord are gripped so rmly that they will not slip in the hook, and with the head still raised to hold the unfinished knot close to the bundle, as shown in Fig. 24, the rod 7 and the hook are drawn down into the head to tighten the knot and the cord upon the bundle. The hookis then returned and the head dropped to open the hook and free the ends of the cord therefrom. The bundle may then be removed from the machine. After the return of the needle-arm, which follows, the machine is prepared to receive and bind the next bundle.

It is obvious that various modiications of our invention will readily suggest themselves to one skilled in the art, and we therefore do not confine the same to the specific construction herein shown and described.
