This invention relates to improvements in bundle binding and tying machines.v

This machine comprehends' improvements in the mechanism for winding awire under tension about va box mounted therein, the.

provision of new and improved wire holding means and means for welding the overlapped ends of the wire binding. D

An object of the invention resides in prol0 viding a machine for wire binding boxes, bundles, and the like of simplified construc-v tion in which a. wire welding mechanism operated electrically is adapted to join the ends of the wire binding. A further object of the invention resides in .providing a machine fork wire binding boxes in which the support for the box mounts a wire holding and welding, mecha nism which are operated by the wlre winding mechanism in-timed relation with each` other' and with said winding mechanism,

A still further object of the invention resides in providing 'a special construction of primary wire holder. secondary wire holder,

- and welding mechanism operated in a predetermined I'manner in accordance with -a cycle of the wire binding operation.

' The invention comprehends numerous other objects residing in the construction of the wire binding machine and the associationn of the various parts, which are more particularly pointed out'in the following detailed de'- scription and in the claims directed to a preferred form ofthe invention, it being $5 understood, however, that'various changes l in the .construction and relation of these v parts may beI made as found desirable without `departing from the spirit and scope o the invention as herein set forth. Y In the drawingsforming part of this apj plication:

cutting mechanism and the weldlng mechawinding pen heral Y 17 dliiven by the` motor 18 mounted onthe Figure 5 is a vbottom -plan view of the structure shown in' Figure4.

Figure 6 is an end elevation-of the mechanism shown in Figure 4 as viewed from the right hand side.

Figure .7 is an enlarged detailed sectional view taken onlines 7-7 of Figure 4.

Figure 8 is a view similar to Fi re 7 showing the welding mechanism in .t e inoperative' position.

The base of themachine is indicated at 1, on which is .mounted a pair of vertically extending parallel standards l 2 slidably mounting the supporting member 4 from the central portion of which extends a stubshaft 5. The supporting member 4 is adapted to be suitably mounted in any desired position of adjustment on the standards 2 for a pur p ose which'will be hereafter described.

A box holding mechanism includes the plate member 6 which is provided with a laterally pro'ecting sleeve, 7 suitably secured on the stubs aft 5, while the lower end of the plate is formed with a laterally projectingsupporting table 8 -for the box an several of the hereafter described mechanisms for holding,' severing, and welding l wire. The plate 'member 6 is slid as indicated at 9 in Figure 1 for` adjustably mounting the clamps10 adapted to 'ri idly securea box 11 lon the supporting tale 8 for receiving` a wire binding. 'The reel 12 carries a suitable supply of wire binding material, which in the accompanying drawing is illustrated as offlat strip form. A wheel 13'is rotatably mounted on the stu shaft 5 and is provided with a brake and normally exerts abraking action through' the tension applying mechanism'i'n dieated at 16, which ma be suitably adjusted to take up wear an vary the braking stubshaft between the extension 7 of the box structure and-thesupporting member 4. It

f drum 14, with which the brake bandV4 15 at' tached to the supporting member 4 engages is to be understood that .a wire of circular cross 'section' or of other .form may be used as well as a flat wire band and it is intended tion. Y

Thewinding wheel 13 is'formed with a groove to receive1 the endless belt to cover those' diferentforms by this invenof base 1 as indicated at 20. The forward end of platform 19 is supported in normally.

raised position by the coil spring 21 so that the motor 18 will normally run free of drivingV cooperation withl the belt and the winding wheel will not beoperated. A foot pedal- 22 is provided on the platform so that it may be conveniently'depressed to move the vmotor into driving engagement with the belt for driving the winding wheel and operating the variousmechanisms through a cycle of movement for Wire binda box, bundle or the like.

in gfhe winding mechanism for -winding the vwire around the box shown more particularly in Figure 3 includes shaft 23 securedat one end to the rim of the winding wheel and projecting laterally therefrom to rotatably support guide Wheels 24 and 25. The guide wheel 24 is aligned with the reel 12 and receives the wire band which is delivered by the wheel 25 to the'box. A pair of arms 26 are mounted on shaft 23 adjacent the guide wheels and rotatably support the tensioning pawls 27 which engage the wire band asl it passes over these wheels holding itin engagement with the guide wheels and causing a desired tensioning thereof as it is woundon the box.

Suitable coil 'springs 28 anchored to the pawls 27 at an end and the arms 26 at the opposite end serve to maintain the pawls in their operative positions. A bracket arm 29 is mountedon the rim of the winding wheel and projects laterally therefrom in spaced parallel relation to the shaft 23. Thisarm rotatably mounts the idler guide wheels 30 on the stubshafts 31 extending therefrom in substantial alignment with the arms 26.

With this wire winding mechanism it will be understood that the wire atall times will -be effectively retained in the guide wheels and that aconstant uniform tension will be applied to the wire binding placed around a box during the full cycle of' movement of the -winding wheel. The wire end when scvered willn'ot in any way affect the winding mechanism vvhich will in `reality hold the end ready to start the next windin cycle.

' The supporting table '8 of the box olding mechanism is 'provided on the free end with a wire receiving lip l32 having a shoulder formed at .33 o n the lower face by the dcpending portion atthe left hand end as Shown in Figure 4 which is substantially the same thickness as the wire employed for The shoulder 33'determinesthe rposition of the free .end of .the wire atfthe start of a binding cycle 'which-'his eny gaged and 'retained inposition by the pri-V binding purposes.

mary wire h older 34-in cooperation with lip 32. The primary holder'34 is formed with a serrated head 35, a weighted end 36 at the opposite"s ide ofthe laterally extending piv- 8v and depending therefrom, soVV that' the4 Weighted end 36 normally moves the head 35 toward the lip 32 to engage the wire end. The primary holder-is .mounted in a manner that the tension applied to the wire end as shown Pat 39 normally tends to move the holder on its pivot with head moving toward the lipY to thereby create a greater binding or holding action lon thewire end to retain it in position against the lip.

A bearing 40 is formed on the underside of the table 8 adjacent the end in spaced'relation with respect to bearing 38.y A shaft 41 is rotatably mounted Ain these bearings 38 and .40 and carries a bevel-gear 42 at the free end adjacent the bearing 40 intermeshin with the bevel gear 43 on the operating sha t 44 rotatable in the bearing 40 and a bearing 45 in the rear thereof. Adjacent bearing38 the operated shaft f41, supports astationary cutter member and wire holding finger 46. This finger. 46 is rotatable on the shaft and is held against rotation relative to the b eal-v portion 48 cooperating with lip'32 as shown 95;

in Figures 4, 5, and 7 for holding the wire end 39 against the lip while the primary holder 1s being engaged, and for receiving the wire end to be severed in amanner to be described.

An electric Welder includes a body 50 having an extension 51 mounting a plurality of spotlwelding electrodes 52 which have electrical connection through the cables, suitably insulated and supported by the table 8 at 53 with a source of power. The body 50 is' loosely mounted on the shaft 41 and has l. limited movement relative thereto through the pin 54 on the shaft operating in then enlarged recess 55, clearlyshown in Figures 7 and 8.` 'The purpose of vthis construction is toV provide for a preliminary movement of the Welder toward operative position with-a subsequent 'relative small movement into.

welding position. Figures 4 and #5 show the, Welder at the end ofthis preliminary movement for convenience iii-illustration.. The full. operation 'and advantage of this constructionwill be hereafter` set out.

on thebody50 'of the'welder and movable A movable-cutter member 56 is mounted 'l therewith` said cutter having-an extension 57 formed with a beveled cutting edge cooperating with the extension 48on the wire hold-l ing finger to sever the wire end after'wind-- ing. The severing operation takes place as the Welder ismoved to the preliminary-position as shown vin Figure 4. The body 50 has an operating arm y58 depending therefrom which carries a roller 59'at-the lowerend by which the spot welding electrodes L the ends oi. the wire band for spot welding vasis said ends.

A secondary wire holder 60 is mounted on the operated shaft 41 and providedwith the serrated foot 61 for cooperation with* lip 32 in holding the wire end 62 locked in tensioned relation just previous to and during the welding operation.. The severin means, Welder and secondary holder are t erefore all operated 4simultaneously with the shaft 41 in the rot-ation thereof and perform their functions separately in this operation. The

secondary holder first engages the end 62 of the wire and maintains the tension thereof around .the box clamping the wire awainst ythe lip v32, and then the severing blade cooperates withthe stationary cutter 48 to sever the end lfrom wire leading'from spool An operating plate 63 is mounted ou the vrear free end of the operating shaft 44 and carries the -laterally projecting roller 64 for cooperation with the cam plate 65 mounted on the rim'of the winding wheel and projects into the plane of the roller 64 for engaging and moving said roller and the operating plate from the position shown in dotted lines in Figure 1 to,the position shown in full lines in Fig. 1. This operation of the plate 63 serves torotate the shafts 44 and' 41 to produce the operation of the secondary holder for engaging the wire end,

the `severing imeans'for the Wire and the movement of the welding electrodes into a position preliminary to engaging and welding the overlapped wire ends. An operating arm 66 forms part of the, cam plate structure and ispositioned to engage the roller 59 and complete the operation of the body 50 to move the welding electrodes into vengagement with the overlapped endsof the wire'band and complete the` placing of the,

band under tension on the box by welding the ends. The loosemounting of the body 50 on shaft 41 permits ofthe relativemovement of the body on the shaft through the` pin and4 recess connection 5 4 and 5 5.

Figure 8 shows the severing means and the Welding electrodes in body 50 in the nor.- mally inoperative position. while Figure 7 shows the preliminary position of the weldingelectrodes at the end of operation by the shaft 41 through the operation of plate v63. A weighted portion 67 on the plate 63 serves to normally rotate shafts 44 'and 41 and rel turnthe parts to theinoperative position of Figure 7. From Figure 6 it -Will be noted that one end of the circuit for welding the wire ends extends to the electrodes 52 while theopposite side of the circuit is grounded at 68 on lthe supporting table 8. f

To bind a box or bundle Awith this machine itis first necessary to place the box or bundle ontable 8 with the ends against plate mount the box-or bundle iii the machine.

The wire end 39isthen placed under tl'ie v extension 48. and against the shoulder 3?` after which `Ithe primary holder isengaged with the end portion, as shown in Figure At the start vof an operation the winding wheel. 13 is usually'positioiied slightly rotated in the direction of the arrow from that as shown in Figure 1, so tliat when the above operations are completed the operator may then depress the ,foot pedal 22 with his foot to engage the driving pulley on the motor 18 with hclt 17 and drive winding wheel`13. The rotation of this Winding Wheel one revolution will wind one strand of wire about "the box, as shown in Figure 1. with the .wire

hold it while the severing member 56 severs the end in cooperation with the stationary `cutter member 48. The severing member 56 being integralwith the body 50, the severing of the Wire does not 'take place until said body 50 is actuated by cam 66. This enables member 60 to rmly grip the wire before the wire is severed, thereby positively maintain- A ing the tension of wire. This operation of shaft 41 moves the welding body and velec-- trodes into the preliminary position so that when the wheel 13 moves slightly farther 1n the direction of'the arrow in Figure 1, the.

arm 66 will engage roller y59 and complete tho operation of bodv'50 to engage welding electrodes 52 with the wire ends and 'auto- 'ub matically lose the welding circuit through the lip 32 and spot weld the wire ends. This welding completes the provision ofthe binding on the box, the wire binding having the same tension when finished as during applicatonv through 'the operation of the parts .as'above mentioned. The foot pedal is released at the completion of this operation when the Wire binding isA finished and the box removed'for the next to receive a bindlnL- l With this construction it will be seen that after' starting the operation is automatic but under manual controlv through the foot lever. The parts are grouped in an' assembly and cooperate in performing. their functions in timed order asv above set forth tosubstantially simplify the construction and operation of a machine of this type. Even the supporting table besides holding the box xfunctions to assist in holding the wire endsian and with the welding material reduction o parts as well as, eooperating in the welding operation as one terminal.V The winding wheel provides a f means of supplying power `from the motor to all operated parts and thereby controlling the operation of the machine.
