PACKAGE-BINDING IMPLEMENT.

Application filed September 30, 1922. Serial No. 591,477.

- This invention is a package binding mechanism of the portable type adapted to be positioned at will on an ordinary package for the performance of the operations of applying a binding wire tightly to sa d package, and of fastening or looking said binding wire in the required tight relation to said package.

A portable machine for the specified purposes requires that the operating parts be capable of easy and rapid operation and without demanding unusual or laborious eft'ort on the part of the workman; that the binding wire be introduced with ease and facility, and that said wire be held securely against slipping in the operation of tensioningsaid wire, and that said wire be uickly disengaged from the machine following the operations of applying and securing said wire; that in tensioning the wire it must be drawn tightly into. contact with the package, or, in effect, that said wire shall be embedded in the material at the corners of the package, to the end that the wire compresses or binds the package, so as to compensate for shrinkage of the wood, and so as to retain the wire from slipping ofl the package in case the wood shrinks to an appreciable extent; that the end portions of the wire be fastened securely together while said wire is under tension, and that the machine may be easily and quickly removed from the engagement with the wire and dismounted from the package. In the invention it is sought to provide a machine which meets the foregoing requirements by a simple construction which is eflicient in operation and is manipulated with minimum labor and effort by the workman.

One part of the invention is a retaining member constituting, an element of a tensoning means, said member being cooperable with a previously shouldered Wire for holding the latter against slipping during the tcnsiouing operation, and said member being controllable for the rapid release of the wire subsequently to the wire tensionine; and fastening operations.

It is to be understood that we do not employ a straightlength of wire and deform it after its introduction into the machine, but the present invention is designed to act upon a wire previously deformed, the retaining member receiving the deformation of such previously-deformed wire In a manner to anchor or hold such wire against sliping a tendency to deform the Wire and make the retaining member the sole means of anchoring or retaining the wire against slip-- ping under tension.

The retaining member is non-deformable,

that is, it-does not in any way change the form or character of the wire used in the machine. Its only function is to anchor or hold a wire which prior to its introduction 01' use in the machine has been deformed, in one way or another, to produce a shoulder acting as an abutment in conjunction with the retaining member as the sole means of effecting such anchorage. In one acceptable form the abutting faces of the deformed part of the Wire and the retaining member are substantially rightangled to the line of pull to insure efficient anchorage without the employment of extraneous means for this purpose.

Another part of the invention is an operating means for applying power to said tension head, the sameembodying a shaft for carrying said head, a Worm gear fixed to said shaft, a drive shaft provided with a worm in mesh with said worm gear, a manually-operable member usually in the form of a lever, and pawl and ratchet mechanism operable by the movement of said member for transmitting the motion thereof intermittently to said drive shaft. Obviously, the operating member or lever is adapted to be worked back and forth by the workman without undue efi'ort,'but the movement of said member or lever in one direction transmits the motion to, the drive shaft, the intermittent rotation of which is in one direction only, the power applied to the lever being multiplied by the worm gear:

ing between the drive shaft and the tension head shaft, as a result of which the tension head is rotated in a manner to place such tension on the wire binder as to embed said wire in the corners of the package.

Other functions and advanta es of the invention will appear from the ollowing description taken in connection with the drawings, wherein Figure 1 is a plan view of the machine showing it resting upon a package and with a binding wire applied to said machine and the package in readiness for tensioning.

Figure 2 is an elevation of the machine looking toward the left in Figure 1,

Figures 3 and 4 are vertical cross sectional views, artly in elevation, taken in the planes indicated by the dotted lines 3-3 and H, respectively, of Figure 1 looking in the direction of the arrows.

Figure 4c is a detail sectional elevation of the pawl and ratchet mechanism, on the lines 4 of Figure l.

Fi ure 5 is an elevation of the retaining -mem or for anchoring a shouldered wire in fixed relation to the machine, said retaining member being releasable quickly for making free the anchored end portion of said shouldered wire.

Figure 6 is a detail horizontal sectionj illustrating the twister, the plane of the sec tion being indicated by the dotted line 66 of Figured l i F i ure 7 is another horizontal section, on the line 7-7 of Figure 5, showing one form of latch for the releasable wire retainer shown in Figures 5 and 8; s

Figure 8 is an elevation similar to Figure .5, illustrating the wire retainer in an open position for quickly releasing the shouldered wire after tensioning and securing said wire.

Figure 9 is a detail view of the shouldered wire with the end portions thereof twisted and locked.

lln the machine shown in the drawings 7 provision is made for supporting the wire tensioning mechanism and the wire twisting mechanism by a suitable frame. in the present example, this frame is in two parts or members,'one of which carries the tensioning mechanism and the other of which parts carries the twisting mechanism, butobviously this construction of the frame is a matter of detail capable of variation within wide limits by askilled constructor.

The frame part A for the twister mechanism includes a base, a, and a housing, a for a suitable gearb to impart movement to the twister B. Sai base a extends forwardly, as at a beyond the housing, and in said housing is a horizontal slot or recess 0, the top surface ofsaid'extension, a, sloping outwardly and downwardly from said recess, 0, in order to provide a guiding surface on which the wire may rest and upon which it eer/nee Z), of the twister is adapted to aline or register with the recess, 0, of the housing.

The machine of this invention is useful,

'more particularly, inconnection with a specified kind of preformed wire, the latter being cut to a length suitable to pass around the package tobe wired, and said wire being deformed to adopt it for insertion into the machine with facility, with a view to efiecting saving of time and labor. To this end, we provide means for retaining the preformed wire for one end portion of said wire to be held or anchored in a fixed relation to the machine, the remainder of said wire in the subsequent operation of passing it around the'paclrage being free until its other end portion positioned by the operator into engagement with a twister and with a ill) rotary head, the latter constituting one element of the tensi'oning means, another element of whichtensioning means is the retaining means adapted for holding or anchoring the deformed end portion of the binding wire. 'This wire, tensioning means does not mechanically grip the deformed end portion of the wire in the sense that saidretainer is characterized by moving parts operable, either-manually or automatically, for a clamping or grippingeilect upon the wire, but, on the contrary, said retaining means is so formed as to cooperate with a shoulder provided on the wire by the deformation thereof, as a result of which the retaining means and the deformation of the wire mutually contribute to the result of holding the wire against cndwise slipping during the operations of tensioning, or tensionin and locking, said wire. A very considera le tension is imparted to the wire, with' a View to adapting said wire to serve the functions of a binder and to retain said wire against slipping oil the package in the event that the wood shrinks to such an extentas to loosen the wire, more or less around the mouse inglysaid retaining means is constructed in "anovel manner for the expeditious release or; the shouldered wire s'ubsequentlyto tensioning and twisting the same.

The retaining meansis shown more particularly in Figures 5, 7 and 8, as embodying a two-part plate, the members of which are indicated at D, D; In its entirety, the plate is provided with a slot (2 for receiving the deformed angular portion of a shouldered wire, and the entrance to this slot is by way of a slot, 03, extending to and through the edge of the plate, the edges or walls of the slot d being relatively inclined to through which the deformed portion of the wire is passed. Intermediate the slots, (1, d, the opposing edges of the members D, D, composing the retaining plate are recessed at d for the reception of a round portion of wire, as will presently appear. One member of the plate is fixed and the other is movable with reference to the fixed member; as shown, the lower member D is fixed, being fastened to the side of the base, a, by' screws 8, 6, whereas the upper memher is movable, being pivoted to the base,

a, by a substantial screw e, although the two members .D, D, of said plate ma be hingiedly connected together as at e in igure 8-v It is preferred to employ a spring as E for normally depressing the movable member I) toward the fixed member D, said spring being shown as being fixedly attached at e to a part of the base or hous= ing and positioned for the free end of the spring to act-upon the unconfined end portion of the hinged plate member D, see Figures 5 and 8.- For locking the hinged member D in immovable relation to the fixed member D during the operation of tensioning and twisting the wire, and to thus adapt the wire retaining means for efficient service in holding the shouldered wire from slipping relatively to the retaining means, it is advisable to use a latch mechanism of one form or another. One form of latch is shown in Figures 5 and 8, as a bolt F slidably and rotatably supported in the movable plate member D, near the free end thereof, said latch bolt being adapted in the operative position of the plate memberD to enter a socket, f, provided in the base, a. The latch bolt is impelled by a spring, f, into the socket) when the plate member D is in a closed operative relation to the complemental plate member D, but when the bolt is withdrawn from the socket f, it may be rotated so as to position the stud or pin f on said bolt out of register with a notch f thus holding the bolt in a retracted position when the plate member D is raised and during the period that produce a tapering throat into and the workman is engaged in manipulating 4 deformed portion a: of the wire is slipped through slot 0 of the base and slot d of the retainer so that said deformed part at of the wire will be received within the slot 0! ol' the two-part retainer, in a position for a shoulder at of said wire to have abutting contact with an edge of slot d, see Figure 6, whereupon the plate member D is pressed downby spring E and it is locked by latch bolt F entering the socket f, thus anchoring the shouldered wire in a fixed relation to the machine by the retaining means D, D. The anchored wire is passed into slot 0 of base a and slot 6 of the twister, then through a slot 9' of another plate G fixed to the base a on the opposite side thereof from the two-part retainer D, D, then passed around the package, and the otherwise free end of such wire is then engaged in the notched edges d of the two-part retainer, then passed again within the slot 5 of the twister and the slot 9' of the plate G, and finally the otherwise free end of said wire is engaged with a rotary head H of the tensloning means. wire is positioned for two lengths thereof to lie in parallel relation to each other and within the slotted'plates, D, D, G, and slotted twister, B, the deformed end of said It will be noticed that the lUU wire being held or anchored bv one plate,

D, D, whereas its other end is attached to head H. The slots in the plates D, D, and G, confine the two parallel portions of the wlre against turning with reference one to the other during the rotation of twister, B,

and as the outer one of the two parallel junction with the two-part slotted retainer serves to preclude movement of the two parallel lengths oflwire at the time the twister is rotated.

The tension mechanism, exce' t. for the two-part retainer, D,-D', iscarried by one mom er, I, of the two-part frame, the other art A ofwhich is the base -a and housing a. his frame member, I, as shown, comprises a base, i, and upright members, if, unitary with said base, i, said frame member, I, being provided with rods, 11, which extend from one side of the frame part, I, and are received in suitable openings (not shown) of the frame part, A, whereby the rods, 1?, couple the two frame parts, A, I, so as to keep them in fixed positions relatively to each other. If desired, one of the coupling rods, i ma be extended through, and for a distance eyond, the frame part, A, as shown in Figure 1, so as to receivefa coiled spring, I, acting against a, collar, 2' for ieldably drawing the two frame parts, A, T, for the bases, (1, 2', thereof to have abutting contact, but this spring may be omitted, if desired, and the rod, 71 be pinned'or otherwise made' fast to the frame part, A, for

, rigdly couplin the two frame members.

y making the support in two parts, A, I, the twisting means and the tension means may be made and assembled separately, the separate assemblage being desirable in some respects from a manufacturing standpoint, but this mechanical detail may be modified by a skilled constructor. In suitable hearings on the uprights, i, of the frame part, I, are journaled two shafts, J, K, positioned at a right angle one to the other, one shaft being above the other shaft. The upper shaft, J, of the said two shafts, is

- provided with a worm, :5, whereas the lower shaft, K, is provided with a worm gear, is, in mesh with said worm, Said upper shaft, J, acts as the driving or power shaft, and it is provided, also, with a ratchet, L. Loosely fitted on the power shaft is a hand lever, L, arranged in a convenient position for operation by the workman. Said lever turns freely on the power shaft for movement in an arc, of which the shaft is the axis, and the stroke of the lever in one direction is communicated by a feed pawl, Z, to the ratchet, L. The lever is worked back and forth by a minimum of effort on the part of the workman, to effect the rotation of the worm shaft intermittently and in one direction, the backward turning of the worm shaft under the pull of the wire, to which tension is applied, being precluded by the friction between the worm gear and the worm, and such backward turning of said worm shaft being positively arrested by a check pawl, Z, hung on one of the uprights,

,i, and engaging with a tooth of the ratchet,

L, see Figure 4. The shaft. K, protrudes at the end from frame part, I, into an overhanging relation to the position assumed by the wire when introduced into the machine, and on this protruding end of said shaft is fixedly secured the rotary tension head, H. In the form of this head shown in the drawings, it comprises a member, h, in the form of a disk, and a. plurality of studs, h, said studs being spaced equidistantly from each other and being unitary with said disk.

The studs project from one face of the disk,

see Figure 4, and are spaced for distances which the wire is bent into contact with said angular corners of the studs, as a result of which the wire is put under tension by the rotary motion of the head, and said wire, due to the angular formation of the studs and the relation of said studs, is held in a practical manner and byfrictional engage ment into the required connection with, or attachment to, the tension head, H, without resorting to clutches or grippers for effecting the fixed attachment of the wireto a moving part. The tension head is positioned adjacent the plate, G, through which the wire passes, and said head turns on an axis at a right angle to the axis of movement of the hand lever, L. Said hand lever is rocked back and forth with an easy motion by the operator for intermittenly turning the tension head, but the power transmitting worm and the worm gear act to increase the effort, or multiply the power, of the lever in a manner to apply'very considerable strain to the wire for placing it under such tension as to embed said wire into the corners of the package,

Referring now to the twister, B, it is horizontally positioned within a portion of housing a, and a portion of base. a, the tooth formed surface, 12 of said twister extending into a marginal part of said housing. In a normal position, the slot, 1;, is in alinement or registers horizontally with thefslot. c, of the housing and with slots, (1, d, of the plate. D, D, and slot, 9, of plate, G, thus enabling the binding wire to he slipped easily into position. The toothed surface, 6 constituting the twister gear is in mesh with the teeth of power gear, I), the latter being provided with a shaft, 6 and with an operating handle, B", The shaft b protrudes at one end beyond the-housing, a, and to it is fixedly secured a cam arm, M, the latter being adapted to strike the cutter lever, N, positioned in the path of said cam arm. As shown in Figures 2 and 3, the cutter lever occupies a vertical position alongside the slotted plate, G, fixed to one side of the base. a, and adjacent to the housing, a, said cutter lever being fulcrumed at its lower end by a screw or stud, n, fixed to the base, a. A spring m is connected to the cutter lever for holding it in a normal position in the path of cam, M. and the movement of said cutter lever under the action of the spring is arrested by a stop, m, posilie isdr'awn so tightly around with the package into operative contact with the tension substantially in the vertical plane of the notch, 0, whereas the other-strand is directed below the cutting edge, p, as clearly shown in Figure 3. The cam is so timed with reference to the twister that after the wire shall have been twisted, as at W, the camw strikes the cutter lever and rocks iton the pivot, 72., thus moving the lever for the cutting edge, 72, to's'evfthat strand or length of wire leading from plate, Gr, to the tension head, H. The cutteris in shearing relation .to the plate, G, and said cutter severs the wire close to one of the twists, w, in said wire, leaving no free or protruding wire ends to catch into packages or injure the hands of the workmen who are required to handle the packages bound with this wire. 1

As shown in Figures 1, 2, and 4, the angular studs, 71., of the rotary tension head are each headed, at W, said head being provided on the stud at the outer end thereof, and to leave a space between the head and the face of the disk, h, into which space the wire is placed, the heads, h of the studs operating to limit the movement of the wire away from the face of the head in the adg'ustment of said wire, while it is free or s ack, head and at the initial stage of placing tension on said wire when movement is first imparted to the tension head. The tension head is rotated intermittently by the rocking move- -ment of the power lever, L, transmitted through the power-transmitting worm and worm gear, a required number of times for taking up the slack in the wire so as to draw it into contact with the surfaces and corners ofthe package. and the rotation of said tension head being continued indefinitely until the wire is wound, more or less, upon the studs of said head, for placing tension upon the wire to the required extent, or until the wire and into contact as to become embedded into the corners of said package and to, in effect, compress or bind the package tightly, and thuscompensate for shrinkage in the wood composing the package.

in fact, there is no limit to the action of the rotary head. in the operation of placing tension on the wire, even to straining the wire to the breaking point, such unllmlted action of the tension head being quite desirable iii-placing tension on wires which may 5 vary in length to suit packages of difierent sizes, and, furthermore, the use of a rotatable lever adjacent the fulcrum stud,

said tension head being rotated headoperated by a pawl and ratchet mechanism allows the machine to be placed in any appropriate position relatively to the pam kage voi small or large dimensions. The operation will in a measure be apparent from the foregoing description, but may be summarized, as 'follows: The machine is placed upon a packa e and a preformed wire of a length suited to the, package is selected or taken from a bundle of such wires, the deformed para-a0, of the selected wire being slipped into slot, d, so as to be received finally within the slot, (Z, within whichthe deformation, w, of the wire is the. shoulder, as, of

snugly received, with contact with the resaid wire in abuttin into the slot, 0, of the frame, the slot, 5, of l the twister, and slot, 9, of retainer plate, G, SaId WIIG being passed below cutter, N, and tension head,.H, and said wire being passed around the package, for the free or 11116011,

fined end thereof to be manipulated as follows: The retainer member, D, is raised tainer, D, D The 1ntroduction.,.of the deformed portion of the wire with the. retain w ll slightly for said free end to be sli ped into the notch, d of the retainer, w ereupon the member, D, is pressed back into position and locked in fixed position by the latch bolt, F, entering the socket, f, thus confining both strands or lengths of the Wire within the retainer, D, D; said free end isagain passed through the twist-er, B, and plate, G,

slow the cutting edge, p, of the cutter lever, N, and finally the free end portion of the wire is'passed between certain of the angular studs, 12., and into contact with the sharp corners of other studs, h, on the rotary head, substantially as indicated in Figure 2. iiaid end of the wire in contact with the studs of the tension head is heldtemporarily. by hand, whereas the power lever, L, is operated one or more times so as to turn the head, H, sufiiciently for the wire to be strained, thus connecting the wire to the studs of the head, whereupon the the hand is removed from the wire and the lever, L, thereupon operated the required number of times to turn the head suficicntlv for winding the wire around the studs. The power lever in conjunction with the ratchet mechanism and the power transmitting worm and the worm gear afiords a simple powerful mechanism, capable of operation withoutundue effort on the part of the workman for. placing tension to the desired extent upon the wire, one'end. of

which is in effect anchored against slipping by the two-part retainer, D, D," and the.

- within the slot of thetwister by the retainer, D, D, and the plate, G, the'slots in which retainer, D, D, and plate, G, pre clude the wire lengths or strands from-turn- .ing one around the other at the points of grasp, by said parts, D, D, and G, when the twister is rotated. I v

The wire having been placed under the required tension by the rotation of the tension head for an indefinitenumber of times, the operator then turns the lever, B, by pulling it toward the front of the machine, the result of which is to impart motion to gear, 'b, and.twister, B, whereby the wire is twisted together at m in Figure 9, the de-- formed part, :20, and one strand of said wire being held in D, D, and the two strands bein -held inthe slot, 9, of plate, G, so as to prec ude rotation of the two said strands at the specified points of grasp, whereby the wire end portions are twisted or'inte'rtwined' and thus securely locked or fastened togeth-. on As the twister completes its operationthe cam, M, impinges cutter lever, N, and rocks the latter for the edge, p, to cut one strand of the wire at a point close to one of the "twists, :0 thus severing that length of wire connected to tension head, H, from which the out wire is readily detached. The latch F,"is now released and retainer membeitfl), lifted with respect to the complemental retainer member, D, thereby releasing the deformed portion, at, and shoulder, at, of the wire from the retainer, D, D, and the machine is now slipped easily and nicklg away from the applied wire. The ever,

', is returned to a normal position, so as torestore the twister to a position in register with the slots in the retainer, D, D, and G, but is not required to restore the tension head, H, nor its power lever, L, to a iven osition, the implement bein in rea iness or operation uponanother binding wire.

The tension head is rotated intermittently .by the action of the power lever and the pawl and ratchet mechanism, movement being imparted to said head upon the stroke of the lever, L, in one direction, but on the reverse movement of the power lever, no slackening of the wire can take place, due to the cessation of the power stroke of said lever,iL, for the reason that the worm gear in mesh with the worm precludes any relaxation of the strain previously applied to the wire, and such relaxation of strain is precluded in a positive manner by -the check pawl, Z, in engagement with ratchet,

L, as a result of which the strain of the wire .under partial or complete tension cannot, dur ng the reverse or idle movement tension headis precluded by the worm and: d by the pawl; and ratchet wormgeari an mechanism. I c

As shown, the base, a, of the frame part,

A, is provided with a post A rearwardly of the housing, a, said post'being unitary with the rearward part, a, and having a head, a, u on which pressure may be applied to ho d the machine from movement during the operations, or tensioning and twisting the wire.
