' Application filed November 24, 1902. Serial No. 132.597. (No model.)

To zZ-Z whom it may concern:

Beit known that I, FRANCIS TEEWILLEGEE, a citizen of the United States', residing at Brookhaven, in the county of Suffolk and State of New York, have invented certain new and useful Improvements in Wrapping- Cord Knotters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains t make and use the same. y

My invention is an improved cord-knotter adapted especially for use in tying the knots in Wrapping-twine when wrapping up bundies; and it consists in the peculiar construction and combination of devices hereinafter fully described and claimed.

The object of my invention is to provide a light and compact machineof this character which is adapted to be operated manually for tying knots in twine while wrapping bundles therewith.

In the accompanying drawings, Figure 1 is a perspective view of a cord-knetter embodying my improvements. Fig. 2 is partly a bottom plan view and partly a longitudinal sectional view of the same. Figp is alongitudinal central sectional view of the same. Fig. 4 is a longitudinal central sectional view of a portion of the same on alargerscale and on a plane at right angles to that of Fig. 3.

Fig. 25 is a diagrammatic perspective view showing the cord engaged bythe grippers prior to the formation of the coil. Fig. 26 is a similar View showing the coil formed by the revolution of the knotting mechanism. Fig. 27 is asimilar view showing the grippers moved in place to put the cord between them into the notch of the Vbight-former and in front of lthe coil. Fig. 28 is a similar view showing Vthe formation of the bight and its drawing into and through the coil. Fig. 29 is asimilar view showing the coil 4 forming sleeve drawn into the outer sleeve to cause the coil -to be slipped over the bight. i Fig. 30 is a similar View showing the coil-forming sleeve moved forwardly to tighten the "coil on the bight, and Fig. 3l is a similar view showing the bightformer moved forward to release the coil after the completion of the formation of the knot.

In the embodiment of my invention here shown I provide an inclosing casing l, which is of cylindrical tubular form and isprovided at its rear end with a pistol-grip 2, whereby it may be readily grasped and operated. The front end of the casing l is substantially semispherical in cross-section, as at 3, and is closed, excepting fora cord-slot 4, which is curved obliquely'to the longitudinal axis of the casing, as shown in Fig. 9 and in other ligures ofthe drawings. The cylindrical portion of the casing is also closed at its rear. end by a block 5, in the center of which on its front side is a cylindrical bore 6. On the front side of the said block is an annular IOO ange 7, which is concentric with the said bore. At a sui-table distance from the front end of the cylindrical portion of the casing is a block 8, which is secured to and. is nonrevoluble in the casing. A block 9 is here shown as attached to the rear side of the block 8. The latter forms the bearing for a revoluble headlO, which is swiveled therein, as at 11, and is provided at its rear end with a miter-gear l2, the same being fast thereto. This head is of tubular form. Its bore, which extends longitudinally therethrough, is angular in cross-section, as shown in Fig. 23, and at the front end of the head, on opposite sides thereof, are a pair of lugs 13.

A longitudinally-movable bar 14, which is here shown as cylindrical in form throughout the major portion of its length, has its' rear portion disposed and adapted to move;

longitudinally in the bore 6 of the block 5 and has its front portion disposed and adapted to move longitudinally in the angular bore of the head 10, the front portion of said bar forming a sleeve 15, one of the functions of which, as will presently appear, is to slip the coil from the coil-forming sleeve while tying the knot. By thus constructing the front portion of the longitudinally-movable bar 14 in the form of a sleeve angular in cross-section and fitting in the cross-sectionally angular bore of the head 10 said bar 14 is adapted to rotate with the said head, as will be underis a longitudinally-movable rod 18, which is' cross-sectionally angular, fits slidably in the cross-sectional angular bore of the sleeve 17, is of suitable length, vand has its outer end, which is adapted to be projected beyond and retracted within the sleeve 17, fiattened on,

opposite sides and provided on one side with a cord-engagingnotch 19. I will hereinafter refer to this rod 18 as the bight-former. It will be understood that owing to the crosssectionally angular shape of the sleeves 15 17 and of the bight-forlner 18 the same rotate l with the head 10 when the latter is turned.

On opposite sides of the projecting portion -of the sleeve 15 are cams 21.

sides of the lugs 13 of the head-cam are pivoted a pair of connected rock-arms 22, which 21, and hence cause the rock-arms 22-to be turned on their pivots, so that the jaws 23 at their outer ends will be moved toward the To the inner` bight-former. Gripping-jaws 25 are pvoted to the outer ends of the rock-arms 22, as at 26, are connected together by-a yoke 27, and the said yoke has an arm 28, which projects from one side thereof. The said arm is provided with a curved slot 29, the ends of which are at an angle toits intermediate portion. A link 30is pivotally connected to the rockarms 22, as at 31, and is pivotally connected to the arm 28 of the pivoted gripping-jaws 25 by avpin 32, which operates in the slot 29. The said link 30 is provided on its inner side with a cord-ejecting arm 33, which is disposed midway between the arms 22, which are provided with the fixed and pivoted gripping-jaws 23 25.

It will be understood from the foregoing description, in connection with Figs. 7 and 23 ofthe drawings, that when the sleeve 15 is moved rearwardly in the head l0 to cause the rock-arms 22 to move the gripping-jaws toward the bight-former the link 30 will coact with the slotted arm 29 to close the pivoted gripping-jaws 25 against the relatively fixed gripping-jaws 23 and that owing to the shape of the slot 29 in said arm '28 the said pivotpin 32 and link 30 will lock the pivoted jaws both in their closed and in their open position, thelatterbeingassumed when the sleeve 15 moves forwardly in the head. The head 10, which` is revoluble, is provided on one side with a radially-disposed arm 34. The link 30 is actuated to close the gripping-jaws, as above stated, at the initial rotary movement of the head 10 by a cam 35, (shown in Fig.. 10 and also shown in Figs. 7, 8, and 9,) which cam is in one side of the casing 1, near the front end thereof.

The rock-arms 22, together with the gripping-jaws23 25 and the means for operating them, constitute the cord holder and feeder, which coacts with the coil-forming, bightforming, and coil-slipping elements, as will presently appear.

Ony one side of the casing is a cord-'cutting sleeve 36. The same may be either of the form here shown or of any other suitable -form.L As here shown, it is provided on opposite sides with cord-receiving slots 37. In the said cord-cutting sleeve is an oscilla-ting cord-cutting stem 38. The latter has a cordslot 39, which coacts with the cord-receiving slots 3 7 of the sleeve 36 to form cutting edges,

whichare effective when the stem 38 is turned to the position shown in Fig. 15 to cut the cord represented at 0o. The stem 38 is here shown as provided with an inwardly-extending shank 40, which has an arm 41, which forms a lever and which by engagement with the arm 34 'of the head 10 causes the stem at each rotation of the said head to be turned sufficiently to cut the cord. It will betobserved by reference to Fig. 10 that the positions ofthe cam 35 and arm 34 are such initially as to cause the cord-gripping jaws to be closed at the initial movement of the head and the cord-cutting device to be immedi- IIO ately thereafter operated to cut the cord. The angular movement of the cord-cutting stem is controlled by the stop 42. A spring 43, which is here shown as disposed in the form' of a coil, but which may be of any suitable construction, imparts reverse move,- ment to the cord-cutting stem after the arm 41 is disengaged by the arm 34 to return the stern to its initial position, (shown in Fig. 14,) with its slot 39 registering with the slots 37 in the cord-cutting sleeve.

In the under side ofthe tubular casing 1 is a longitudinal slot 44. In the same a trigger 45 is disposed for longitudinal movement. The said trigger has a plate 46 at its inner end, which bears against the inner side of the casing, as is clearly shown in Fig. 1l, and is provided also with a guide-plate 47, which is detachably secured to the trigger, as by pins 48, and which bears against the outer side of the casing. On the inner side of the plate 46, which participates in the movements of the trigger, is an arm or link 49, which is provided in one side near its rear end with a slot 50. The said arm is here shown as b eing engaged on its under side by a spring 51 to normally press its rear end inwardly.

Hence said arm 49 is a spring-arm. Within the scope of my invention said arm 49 may be in itself a spring, and the spring 51 may be omitted. I do not, therefore, limit myself in this particular.

In the under side of the casing 1, immediately in rear of the block 8, is an opening 52, which is closed bya bridge-plate 53. On the inner side of the latter is a crescent-shaped pawl 54, provided with the arms 55 56.4 A spring 57 bears on the said pawl near its pivotal portion, the function of the said spring being to hold the pawl momentarily in either of the two positions assumed thereby. A master-gear 58 is provided with a drum 59, on which a strap or operating-cord or other liexible operating element 60 is adapted to be coiled and uncoiled. One end of this strap or cord is attached to the said drum and adapted to be wound thereon, and its opposite end is attached to the trigger 45, whereby when the trigger is moved rearwardly by the finger of the operator the strap or cord 60 will be caused to uncoil from the drum 59, and hence turn the master-gear in one direction. The said master-gear and its drum are loose on a`shaft 61, which has its bearings respectively in the bridge-plate 53 and in the block 9, and the said shaft has a mitergear 62 fast thereon, which miter-gearrengages the gear 12 of the revoluble head 10.

The shaft 6l is provided on one side of the` drum with a cam 63, which has a stop-shoulder 64. The latter is adapted to be engaged and disengaged by a pawl or detent 65, which 4has a projecting end provided with a wedgeshaped cam 66. The detent-pawl is normally kept in engaged position with the stopshoul der of the cam 61 by a spring 67. Thesaid detent-pawl and the said spring are connect ed to and carried by the drum 59. The crescent-shaped pawl 54 isdisposed within the orbit of the cam 66 of the detent-pawl 65. It will be understood that when said detentpawl is engaged with the stop-shoulder ofthe cam 63 the drum and master-wheel will be locked to the shaft 61 and will cause the latter when the trigger is drawn rearwardly to turn the gear 62 in one direction, and hence rotate the head 10.

The wheel 58 engages a gear-wheel 68, which revolves on the cylindrical portion of the sleeve rod or bar 14 and has on its rear side a drum 69, on which is coiled a spring 70. The latter is wound by the rotation of the wheel 68 and drum 69 ensuant on the rearward movement of the trigger 45 as the strap or cord 60 is unwound from the drum 58, and hence the function of this spring is to rewind the strap or cord 60 and return the trigger 45 to its normal position. (Shown in Fig. 4.) It will be understood that the stop-cam 63, detent-pawl 65, spring 67, and crescent-shaped pawl 54 cause the gear 62 to be turned to rotate the head 10 during the rearward movement of the trigger 45 and disengage said gear 62 from the gear 58 and drum 59 during the retrograde movement of the trigger by the spring 70, so that the head 10 is turned only in one direction, and at each rearward movement of the trigger 45 the said head makes only one revolution. During the initial rearward movement of the trigger 45 and while the drum 59 is being revolved in one direction by the unwinding of the strap or cord 60 `the detent-pawl 65 is in engagement with the shoulder 64 of the cam 63, hence causing the gear 62 to rotate, and thereby cause the head to revolve. As the drum andthe head complete one revolution ithe flange 66 of the'detent-pawl passes on the outer side of the crescent 54, thereby causing `the detent-pawl to be disengaged from the shoulder 64, hence stopping the revolution of the head, while permitting the drum to continue to revolve. On the reverse rotation of the drum by the action of the spring 70 and gears 68 58 the flange 66 passes on the inner side of the crescent, thereby turning the detent-pawl into position to rengage the shoulder 64.

The drum 69, which contains the spring 70, is provided on its rear or inner side with a head or closure 7l,`which forms a casing in which one end of the spring 70 is secured, the other end of the spring being, as hereinbefore stated, attached to the drum. A cylindrical sleeve 72, which is of greater di ameter than the bar 14incloses that portion of the latter between the block 5 and the head 69. The rear end of the said sleeve 72 is engaged by the annular llange 7 of said block 5. The said sleeve 72 is spaced from and maintained' in concentric relation to the bar 14

byicollars

73, 74, and 75. The bar 14 is slidable in said sleeve 72 and is provided with a liange .75', here shown as a collar,

which flange is at a suitable distance from the rear end of the said bar and is engaged by a coiled extensile spring 76, which bears between said ange and the block 5, the function of the said spring, as will be understood, being to move the bar 14, and hence its sleeve portion 15, forwardly. The said bar 14 is also provided with a stop 77, which when said bar is moved Irearwardly is engaged by a spring-pressed detent 78, which is carried by the sleeve 72. It will be observed by reference to Figs. 4, 5, and 6 that the stop 77 and detent 78 have cam-faces and that the said stop is automatically engaged by the detent 78 when the bar 14 is moved rearwardly, so that said bar becomeslocked by said detent and stop and locked in its rearward position, as shown in Figs. 5 and 6.

The bar 14 has a vertical slot 79, which eX- tends therethrough, and in which is pivoted a secondary trigger 80, which has on its upper side an arm 81 and on its lower side a pair of downWardly-diverging arms 82 and 83, the latter being in rear of the former and adapted to be engaged by the rear end of the springarm 49 of trigger 45 when the latter is moved rearwardly, the arm 82 being adapted to engage the slot 50 of said arm, so that the trigger 45 at the rear limit of its movement will be locked to the secondary trigger 80, as shown in Fig. 5. slot 85, which clears the arms 82 83 of the secondary trigger. The collar 75 is secured to the sleeve 72, and the bar 14 is slidable in said collar. The latter is provided on its upper side, where it is coincident with the slot 84, with a stop-shoulder 86 and a cam-face 87. The bar 14 is provided on its upper side with a trip-cam 88, which is movable therewith. The collar 74 is also fixed to the sleeve 72, so that the bar 14 is slidable therein and is provided on its upper side, where it is coincident with the slot 84, with a stop-shoulder 88a and a cam-face 89. The collar 73 is also fixed to said sleeve. The latter is provided on opposite sides with longitudinal slots 89a, 90, and 91.

At the inner end of the bight-former 18 is a cross-pin 92, which travels in the slots 89LL and to which is attached a slidable collar 93, which operates on the sleeve or tubular portion of the bar 14 and is provided with a rearwardly-extending arm 94, which is provided with an opening 95, which is a longitudinal slot, asimilar slotted opening 96 near its rear end, and the'extreme rear end of which arm is provided with a cam-face 97, adapted at the eXtreme rearward limit of the movement of said arm with the bight-former to-engage the detent 78 and detach the latter from the stop 77. A coiled eXtensile spring 98 on the bar 14 bears between the stop-collar 74 and the said slidable collar 93. The function o f the said spring, as will be understood, is to move the bight-former 18 forwardly to project its notched outer end beyond the coilforming sleeve 17. The arm 94 of collar 93 The sleeve 72 has a longitudinal,

is provided on its inner side near its front end with a spring-detent 99, which is adapted on the rearward movement of the hightformer with relation to the sleeve 72 to engage the stop-shoulder 88a of the stop-collar A74, as shown in Fig. 6.

On the sleeve portion of the bar 14 is a slidable collar 100, which is connected to the longitudinally-movable coil-forming sleeve 17 by a pin 101, which operates in slots 102, with which the sleeve portion of bar 14 is provided, and also operates in the slots 90 of sleeve 72. This collar 100 has on its upper side a tripcam 103, which is adapted-to engage the rear end of the spring-detent 95 to disengage the latter from the stop 88a. The said collar 100 is also provided with a rearwardly-extending spring-arm 104, having at its rear end a camdetent 105, adapted to automatically engage the stop 86 and to be disengaged therefrom by the trip-cam 88. A coil extensile spring 106 on the bar 14 bears between the stop-collar 75 and the collar 100, and the function of which is to normally move the coil-forming sleeve forwardly. On the sleeve 72 is a guide 107 in which the arm 94 operates.

The operation of my invention is as follows: In the 'initial position of the knotter the coil-sleeve 17 has its front end projected beyond that of the sleeve 15, the front or outer end of the bight-former is projected beyond that of the coil-former sleeve 17, the rock-arms 22 are moved outwardly by the engagement of the cams21 with the cams 24, and the position of the link 30 is such as to open the gripping'- jaws 25 23 of the cord holder and feeder, as shown in Fig. 7, the spring-detent 99 being disengaged from the stop 89, the spring-detent 105 being disengaged from the stop 86, and the detent 78 being engaged with the stop 77, as shown in Fig. 5, the arm 81 of the secondary trigger being at all times engaged with the rear end of the slot 9G of the arm 94, as shown in Fig. 5, and the trigger 45 being at the forward limit of its movement, as shown in Fig. 4. A cord having been placed around the bundle in the usual manner and drawn tightly therearound, the ends of the cord are engaged by the guide-slots 4 of the casing 1, and the jaws 2 3 25 being opened said cord is by the said guide-slots directed between the said jaws. The trigger 45 is then drawn rearwardly by the foreiinger of the operator, who grasps the knotting device by the pistol-grip thereof. As the trigger moves rearwardly the head 10, carrying the cord gripping or holding and feeding devices, rotates, as Vhereinbefore described, and the initial rotary movement of the head causes the grippingjaws by the engagement of the link 30 with the cam 35 to close upon the cord, so that portions of the cord between the arms 22 are stretched and held against the arm 33, and the further rotary movement of the head 10 by reason of the coaction of link l30 and cam 35 causes the rocking arms 22 and the lOO IlO

grippingjaws carried thereby to swing to-4 ward the bight-former. This is shown in Fig. 9, the closed position of the gripping jaws being shown in Fig. 8. At the same time the coaction of the arms 34 41, carried, respectively, by the head 10 and the cordcutter, causes the latter to cut the cord, which has previously been disposed in the slots of the cord-cutter., The head makes one complete rotation, vand the cord being gripped by the gripping-jaws, and the latter and the sleeve 17 describing a rotary movement, as hereinbefore described, the result is that the cord is first wrapped around and on the projecting end of the sleeve 17 to form a coil therein, and that portion of the cord between the grippers is carriedv to and dis- 'posed in the notch 19 of the bight-former in rear of the coil. (See Fig. 27.) Immediately after having thus placed the cord in the notch in the bight-former the gripping-jaws open to release the cord, and the arm 33, which is carried by the link 30 and is operated by the cam 25, moves the cord out of engagement with the gripping-jaws, thus insuring the release of the cord by the gripping-jaws. As the head of the sleeves 15 17 and the bightformer complete this rotary movement the spring-arm 49, which moves with the trigger 45, passes under, and its notch 50 becomes engaged by the lower end of thearm 82 of the secondary trigger 80. This rearward movement of the trigger 45 by means of the gearing hereinbefore described causes the spring to be wound up, as hereinbefore stated'. The trigger 45 continues to move rearwardly by being drawn upon by the finger of the operatorafter its spring-arm 49 has thus become enga ged with the secondary trigger, and the upper arm 8l of the latter being,`as hereinbefore stated, in engagement with the rear end of slot 96 in the arm 94 said secondary trigger is prevented from turning in a vertical position by the trigger 45, thereby causing the bar 14 to be moved rearwardly against the tension of the spring 76 and the stop 77 to be engaged by the detent 78. During this movement the relative positions of the sleeve 17 and the bight-former 18 are unimpaired. This movement of the bar 14 is accomplished during the formation of the coil around the coil-forming sleeve 17 and the engagement of the cord in rear of the coil and within its radius by the notch 19 of the bight-former 18. When the bar 14 has been thus locked in its rearward position, the operator releases the trigger 45, whereupon the spring 70 acts to draw the said trigger forwardly, and the same being connected to the secondary trigger by thelink'arm 49 the secondarytriggeris turned on its pivot, thereby causing its upper arm 81, which is in engagement with the arm 94 ofthe collar 93, to move rearwardly, and hence said collar and arm are drawn rearwardly against the tension of the spring 98, thereby causing the detent 99 to engage the stop 89 and the bight-former to move rearwardly in the sleeve 17 to form a bight in the cord and draw the same within the coil-forming sleeve 17, on which the coil is, andalso compressing the spring 98. The continued rearward movement of the arm 94 by the pivotal movement of the secondary. trigger causes the cam 97 to trip the detent 78 from the stop 77, thus releasing the bar 14 and causing the spring 76 to move the said bar forwardly, so that its sleeve 15 slips the coil'from the coil-former sleeve 17 over the bight ofthe coil. At the limit of the forward movement of the bar 14 by the action of the spring 76 the cam 88, which moves withsaid bar, disengages the detent 105 from the stop 86, hence causing the spring 106 to move the sleeve 17 forwardly over the bight-form er, which remains stationary, and said sleeve 17 tightens the coil on the bight,. I The cam 103 of the collar 100, whichfis thus moved by the sleeve 17 by the action of the spring 106, then engages the detent 99 and releases it from the stop 89, whereupon the spring 98 moves the bight,-former forwardly out of the sleeve 17, thereby releasing the cord after the completion of the operation of forming the knot. It will be understood that as the secondary trigger completes this pivotal movement the arm or link 49 disengages the arm 82 of said secondary trigger and that on the next ensuing movement rearwardly ofthe trigger 45 by the pressure of the iinger of the operator to make an-A other knot said arm or link 49 first engages the arm 83 of the secondary trigger to turn the latter to the position shown in Figs. 4 and 5 and cause the notch 50 to be engaged by the arm 82.

I do not desire to limit myself to the precise construction and combination of devices herein shown and described, as it is evident that modifications may be made therein without departing from the spirit of my invention and within the scope of the appended claims.
