In describing the illustrated embodiment of this invention, in connection with the accompanying sheets of drawings, specific termswill 'ne employed for the sake Aof clarity, but it is to be understood the scope of said invention is not thereby limited; each such term being intended to embrace all equivalents which perform the same function for an analogous purpose.

For exemplication only, the` form of embodiment of this invention illustrated will be hereinafter explained in its capacityfas apackage binding device; while the term single isintended to refer generally. to individual articles,

parts and limbs of. living bodies, Vas well as inanimate objects and things; Similarly, wherever in the following descriptive :matter theV term collective or itsequivalents refers to multiple articles, and so forth, packed together, in bundles, stacked, or otherwise arranged for unit bonding or tying: while itis to be expressly understood the jaws of the device are normally open when inoperative.

Referring now, more in detail, to the drawings, the novel package binding device therein shown briefly comprises opposing hollow jaws I, 2, the former of which is hereinafter distinguished as stationary while the latter is designated movable, for purposes of differentiation; as Well as an independently movable handle or grasp 3.

'I'he jawsv I, 2 are interpivoted, while the former embodies a tubular and rectangular-section part or bow 4, approximately tangential in respect to opposing cup-sections 5, with a suitably-shaped handle or grip extension 6. Somewhat similarly the opposing jaw 2 comprises a rectangular-section bow 'I and opposing cup-section 8, with which the independently movable grasp 3 aforesaid is cooperatively related; while the bow 'I is provided in one face with a movable cover section 9, hinged thereto at I0, providing access to the interior for purposes 'later on duly set forth, andsaid cover section is held in closed position by suitable retainer means II.

The aforesaidparts are pivotally mounted in cooperative relation through the medium of an axially-shiftable pin or arbor I2 afforded support in sleeve-like members or devices I3, I4, Fig. 4 more particularly, and respectively comprising attached retainer-flanges I5, I6, as well as embodying relatively-stepped ratchets I'I, I 8, with intervening spacer sections I9, 20. These spacer sections I9, 2|] provide pivotal support for the cup'sections 5, 8 of the respective jaws I, 2 by engagement through central holes 2|, 22 therein; and between the inner ends of the devices I3, I4 there are rotatively mounted on the arbor I 2,-adjoining binder` medium tape and securing medium strip supply reels 23, 24, respectively. Ifhese reels 23, 24 have associated movement restraining means 25, coactive with the circumferential edges thereof; such means being preferably in the form of spring strips xed to the lower circumferential walls of the cup portions 8 by attaching means 26, and whereby the reels 5 23, 24-are restrained against too free rotation, as

hereinafter fully explained.

In ordervto provide means whereby the fully Wound reels 23, 24 may be readily inserted into, and removed from the binding device, when the respective supply of binder medium, such as paper or fabric tape 2`I, or the securing strip of metallic foil 28, for example, thereon becomes exhau'sted, the hereinbefore referred to shftable arbor I2 is providedv at one end with a finger hold 29 which affords means whereby it can be axially moved; aand at the other end said arbor I2is formed with a longitudinal groove 36 for engagement witha corresponding-section positioning tongue or spline 3|, in the adjoining portion of the bore of the sleeve device I3. To secure or hold the arbor I2 against rotation when inserted, it is provided with a radial hole 32 for registration with a similar diameter hole 33 through the flange I6, and a lock-pin 34 engages saidholes under the influence of a retainer spring 35 attached to the flange I6'by appropriate means 36, while said spring is conveniently formed with a finger projection 31, whereby provision is made for lifting the pin 34, in an obvious manner. In addition, the arbor I2 is provided with spaced radial holes 38, 39 for temporary reception of the inner end part of the lock-pin 34, as later on fully explained.

Referring now to the independently movable grasp 3, and as readily understood from Figs.

1-4,k more particularly, it will be`l seen: that saidl y grasp is .of trough-shape: inl cross-section. with a.

concaVo-convex outer endg40 and parallel; eyeended link portions4 I, 42`Lforpivotal support onf the sleeve devices I3., I4i between the bow cupsections v51.8; 'saidf portions; having intermediate their ends inwardly-directed; lugs 43, engageable' through ancualj slots' 44 in cup sections. 8; and

affording anchorageat;` 45;'for oneendof: an asso.- ciated recoil spring: 46;.th'eotheri ends whereof are similarlyfattached;tofgpins4I.l in said'oup sections; ThusV it will bei: seenr the: independentlyv` movableY grasp 3" is' spring-influenced outward:- ly, see; Figs.. 3f and 9 tolbestsadvantage.: The

link;1;xorti'on 4-'L of.V the grasp 3,.as bestI shown in` Figs.. 1,. 2; and 4'.. is provided' with an extension i8 having. a. stud 4191i affording pivotal-'bearingfor anactuator dogv 50.*; maintainedin.' operative engagement withV -a twelve-tooth. ratchet IT by' a springy-tongue 52T securedV within the cup.- section 5: andenga'ging the heel V53 otsaid dog; The

mittentlyL moved. angularly inwards-1 relative to I the stationary jaw gripextension- 6, the respective stepped ratchets I T; I8v are concurrentlyY rotated-a denite-degree determined bythe shape of their teetlr and thel operatively coordinated; binder-tape and securing-foil'ZF, 28, feed mech'- anisms now to be described.

These feed mechanisms being substantially individualv and ofdiierential throw, that associatedwith the binder tape 2'I4 will Iirst be; detailed with reference" to Figs. 3-9more Iparticularly, and from which it will'be readily understood said tape, on leaving the `reel 23 passes outwardly over a cross portion orbridge piece 56, intermediate the circumferential Walls of the cup sections 8, and is threaded upwardlythrough an appropriate guide tube 51'! rigid` withinv the movablejaw bow 1', as well as the cross-cuts or diametri@ notches 58 of suitably` located stationary guide'studs 59 also interior of `said bow. Ready accessibility to thev jaw-bow interior is aiordedv by the hinged cover 9; and it' will be obvious from Figs. 3v andl 5 how the upward threading of the bindertape'rl 2T is effected; it'

being likewiseself-evident said-tape4 is inclined inwards from the guide tube 56 to a central position for entry into the jawv head 60V for purposes hereinafter set forth. Associated with' the parts just described is a flexible feeder or pusher 6I afforded suitable guidance along the, inner wall 62 of the movable-jaw bow-portion T. This pusher 6I is conveniently inthe form of a flat handhaving attached toits lower end, by rivets or the like 63, Fig. 5.a' yoke or fork 64 embodying av shouldering 65 and spaced legs 615';V the latter being formed with camming sections, 6T.

and terminal projections or dog portions 68. for

operative coaction with the, teeth of the ratchets- I 1, hereinbefore referred to, whereas the free end parts 68' of such dog portions engage rigid stop-pins I8 in the cup sections 8. It is to be herenoted the yoke shouldering 55 serves as` an abutment for the engaging end of the pusher, 6| to effectively prevent lateral movement thereof ;k while arcually allocated pins TI, 12, also ilxe'd in the cup sections 8, respectively' coact with the camming sections 61 and opposing'faces of the spaced legsA 66 to accommodate and limit the combined reciprocatory andA oscillatory move- Y normally engaged' between the cross-portion orl ments of the pusher-fork` incidental to4 oper..- ative coaction of the ratchets; ITI with' the' dog'. Dfrtions, 68, asi hereinafter further amplified..

Somewhat similarly the: substantially-narrower securing; strip orfoil 28, asitzleavesthefreel 24, passes? over the. bridge-piece: 58 upwards; throughzaguide tube; 1:3 to axplane transformer" device '14;V This transformer. device14: is pref-y erably; in the.: nature; of.M a. flattened, arcually'- shaped, tube; having. thel respective entrant and.

exit; `ends 75,1, 'I6-,twisted into right-angled. relaition; and said transformer is: rigidly xed withini the bow 'I by securingimeans' 1.11,. while-tha:

exit end'. T6: may be: longitudinally split at 18;

with `pins 8] aiording anchorage for the one end-`v of Vrecoilsprings 88; the other extremities ofsaid springs; being correspondingly attached to anchor-studs 8'9'; rigid within' the cup sections 8. The clogging `claws 85, itwill be seen, engage the' teeth of`the`ratchets' I3L in opposition to the pull' ofA the' spr-ings, while stop pins 80, also rigid within the cup sectionsv 8; limit the downward movement, as viewed in the drawings, of the pusher-fork legs 84, in an obvious manner. 4At this juncture it isV well to remark that: the flexible-pusherSI has associatedrecoil means, con-A veniently in the form of spiral springs 9I supported by studs 92 rigid within the cup sections 8, such springs having their outer ends an-4 chored at 93 to said cup sections 8 withV their.v innerk Iends 94 engaging lateral lugs. 95, Fig. 5, of the pusher-spaced legs166, in a manner clearly apparent from the drawings.

Referring now to they movable-jaw bow head` 60 and' the confronting bow head 96' of the stationary-jaw I and themore particularly related.,

Figs. 10`15v and 22, itis to' be remarked theexiblepusher 6I i's fastened by securing` means 91 to the feed device proper,v which comprises a 'shoeV 98 having' spaced-"ears 9.9., aording pivotal'y connection, by a hinge pin |00, for thespacedapertured part or pivot IIlI of a forwardly-projecting binder-tapefeed-device |02'. This device I 021 is formedwith a leading cross-piece |03 :at a relatively higher level than said device, andtheears I 0I, aswell as a centralco-planar tongue |04 and a sidel arm |05. having a downward curvature, forV purposes hereafter explained, and as best shown inY Figs. 1G',w llA and 22. The hinge `pin |00 has rectangular-section ends, |06 for sliding engagement in opposing. guide-grooves |01: of a housing structure or block; |08, snugly fitted` in the head. 60, and heldin lplace by means further-'on set forth.V A flat spring I 09` secured atA IfI-0, Fig.

22, to the shoe 98 and engaging on the device pivot' '|'0I serves. to maintain the latter normally at rest; while a stirrup-spring IIfI` havingA por-v tions I I2 coiled around studs. II3, projects laterally fromv the feed-device |02, with thev free endsV abuttingv ears I |34. integral. withv said devicef; whereby the forward end of the bindery tape 27|; is

loopr` of' said stirrup-spring III' and the'crosspiece |03 of the feed-device |02, as long as thereY is any supply to draw from.

formed to provide upper and lower, communicating and open-ended, hollows |15, |16, respectively, the former ||5 having at ones-ide a connecting slot |11, Figs, and 21, with upper and lower opposing recesses |18, for a purpose hereafter set forth. Rotative within the upper hollow ||5 is a feed drum 119 `for the vertically turned portion of the securing-strip foil 28 which is conducted thereto, from the exit end 16 of the plane transformer device 14, by way of an aligned slot |20 in the block |08; and said strip foil is maintained in frictional contact with the feed drum H9 by a coactive roller |21, the axis portions |22 whereof are rotatively journaled in the connecting slot |11, under the inuence of inwardly-active cent-rally-indented leaf-springs |23 engaged at their ends in the opposing upper and lower recesses l1 18, as clearly understandable from Figs. 12 and 21. The feed drum 1 19 is xed on a tubular shaft |24, in turn rotative on a stationary shaft |25 having a head |26 seated in a recess |21 in the lower bridge portion |28 of the block |08, said shaft being restrained against movementby a cap-screw |29, which, it will be remarked, also serves to rigidly secure said block in position within the bow head 60 as hereinbefore premised. Integral with or secured to the lower end of the feed drum |19 is a ratchet l|30V operative by an inwardly-innuenced angular pawling device |31, pivoted at |32 to an arm |33, integral with the hub portion |34, of the ratchet '|30 and feed drum |19, said arm having an aligned part |35, diametrically spaced thereto,

and providing pivotal connection at |36 for an. 4actuator link |31, having aslot |38 at its other ment in a complementally reduced part |4| of a manipulator device, comprehensively designated |42, andto which the flexible-pusher 19 is rigidly connected by rivets |43` for example. This manipulator device |42, asfbest understood from' Figs. V13 and 24, comprises a somewhat channelsection body-portion, one ange |44 whereof being provided with a rectangular-section, for exturning movement forwardly, as well as a central pin-projection |65 at'the outer end remote from the pivot |59, engaging in the slot |38, Figs. 10, 11, 20 and 21, of the actuator link |31 for Vactuation of the latter, as later on fully clarified.

The cutter |46 is formed with an inclined knife edgeV I 66, Fig. 24,-and at the remote end has a hole |61, Figs. 20 and 21, for coupling connection of one end |68 of a retractile spring |69, the remote end whereof being anchored within the bow 1 at an appropriate location (not shown) so as to normally exert an inward pull on said cutter, as readily understandable by those convers-ant with the art. The cutter |46 is also furnished with a lateral arm |10, Figs. 14, 20 and 21, projecting outwardly through a movement limiting slot 11| in the wall of the bow 1, and terminating with a iinger hold |12, whereby said cutter is manually shifted to effect severance of the securing strip or foil 28 as, and when, desired.

The actuator-link |31 is provided with a guide projection |13, Figs. l0 and ll, having sliding engagement with the upper face of the manipulator flange 44 to prevent downward movement, and

to ensure steady operation of said link; while there is pivoted by a screw |14, Figs. 20 and 2l, to the manipulator |42, with interposition of a spring-washer and lock-nut |15, a latching device |16 engageable with a notch |11 in the cutter member 146;,said device having an inclined projection |18 whereby it is movable to arrest the cutter |46 in retracted position as later on again referred to.

Seating on top of the housing block |08 and pivoted scissor-fashion to the tubular shaft |24 are cooperative binder-tape narrowing levers |19, Figs. 17 and 18, under the influence of a bow-spring |80 having the ends |81 engaged with the notched-heel portions |82 of said levers; while the remote ends of the levers |19 are formed with arcual serrated and plain sections |83, |84, respectively; said latter sections having curvilinear offsets |85 for coaction with the terminal inner edges |86 of the manipulator spaced arms |48, |49, as later Von explained in connection 'with the operation of the binding device.

ample, slot |45 affording slidable guidance for a V cutter member 46; whereas the paralleling ange |41 embodies spaced arms |48, |49, also preferably of rectangular' cross-section. The arm 48 embodies a relatively-stepped extension |50 with a vertically-rounded lug 15|, for a purpose later explained; while the arm |49 has a Y similarly-stepped extension |52 with an angularly-related or pendent portion F53, likewise embody-ing a vertically-rounded lug |54; said portion |53 having secured thereto, by attaching means |55, an angled-tappet |56 with the free extremity rounded at |51, also for purposes hereinafter Afully clarified. In addition to the foregoing, the flange |41 of the manipulator device |42 is provided on` the inner face with spaced lugs |58, see Fig. 14 to best advantage, havingv |60 embodies an eccentric a stop-tooth164 in the device 42 for limitingitsj stepped guide ngers or prongs |81, best seen in Fig. 16, are secured to the jaw head 60 by suitable means 188 with the forward portions seating in slots |89 with projection beyond the outer end wall of vsaid jaw head, as visible also in Fig.

Referring now to the Vhead 96 of the stationary orY receiving jaw I, and referring more particularly to Figs. l0, 11 and l5, said head has rigidly secured therein upper and lower spaced shelves |90, 19|, respectively, for support of mechanisms, now to be detailed. Seating in a recess |92 in the lower shelf |9|Yis the head |93 of a station-` ary shaft or arbor |94 secured against rotation by a, cap-screw |95, and said arbor aords pivotal bearing for a tubular shaft |96 seating on the lower shelf ISI with free passage through the kupper shelf |90. Freely pivoted on the tubular shaft |96 above the self |90 are cooperative scissor-liketape narrowing'levers |91, Figs. 17 and 18, under the inuence of a bow-spring |98 havings its ends engaged at |99 inthe notched heel portions 200 of said levers; such levers having arcual serrated and plain sections 20|, 202, respectively, for operative coaction with the planarly opposing levers |19. In connection with the levers |91, spaced stops 203 are provided on the shelf to' limit their degree of opening; while it is to be here particularly remarked that both the levers i119 and llevers ITB-lare l'respe'ctiv'ely formed with outset teeth i204, :nsffor onnoning action upon `the securing 'strip orfoil 28, asf-later .onfully clarified.

k alignment of the devices 263'with the downwardly `stepped portions 212 of the guide-prongs |81, it

will be apparent the several levers |19 and |91 are'prevented from lifting, or relative upward flexure; while it is to be further remarked the innenedges of the prongs |81 and devices v263 have'opposingly inclined edges 213, 214, respectively, for a purpose hereafter set forth.

In addition to all of the foregoing and in order to effectively prevent any excess binder tape, as

.well as for supporting bunched articles or things,

from falling in between or getting pinched by the confronting end faces of the jaw heads 66 and 96 Aduring closure, use is preferably made of the guard means shown in Figs. 32-34, inclusive.

This means conveniently comprises a springwire guard 215 carried by the head 96, and coactive flanking guards 216 pivotally supportedA in loop offsets 211 of the head 66. The guards 215 each embody a stem 218 with a stop shoulder 219 and an open angularly-shaped head 286, while the lower portion 28| of said stem is inwardly bent at right-angles to the plane of the head 286, for engagement by the curvilinearly flexed tongue 282 of a leaf-spring 283 secured to the underside of the jaw 66 by suitable means 284. On the other hand, the guard 215 embodies relatively spaced coils 285 with a connecting loop'286, wherebysaid,

guard is attached to the head 96 by a clampscrew 281, with the coils 285 partially engaged in an opening 288 providedfor their reception in the crown of said head. From the coils 285 extend divergent portions 289 with spaced arcual;

continuations 290 and straight extensions 29|, with terminal angularly-contoured loops 292; said extensions 29| and loops 292 being ,outwardly stepped for overlap with the heads 286 of the fectively prevent rotation of the respective Vguards 216. f

Having explained the structure of the improved binding device of this invention, the use and operation thereof will now be described, it being again emphasized that normally the jaws I, v2 are open. Now it will be readily seen that in vaccordance with the size of the device andthe extent of nort mal separation of the jaw heads 66, 96, the bows 4, 1 can be readily passed about any article, such as typically indicated bythe referenced, Figs. 10, 11, 30 and 31, or bunch of articles as similarly designated b in Figs. 32 and 33, capable of entry between the confronting ends of said jaw heads. The user now draws the grasp 3 towards the grip extension 6 of the stationary jaw I with initial closure of the jaws I, 2, and concurrent operation of the pawling means 49-5I as hereinbefore explained, with incidental rotation ofthe ratchets I1, |8 counter-lockwise and resultant projection of the binder tape pusher 64 from the position of Fig. 3 to that of Fig. 8, as restricted by the stop pins 16, 12, with the dog portions 68 of said pusher ready for snap release from the associated ratchet teeth, and return of the pusher 64 under action of the spiral springs 9|. Projection of the pusher flexible component 6| forwardly moves the shoe V98 and associated binder-tape grip |62 from the full-line position of Fig. 10 to the dot-and-dash indication in said gure with consequent rocking of the trap-door device 236 on its stub axles23l, 232 angularly-forward in the head 96 by impact of the outer end of the side arm |65 of the grip |62 against a projection 236-Figs. 10, 22 and 23-flanking the relatively confronting arm 233 of the device ,236, as typically indicated by dot-and- Ydash lines, also in Fig. 10, and placement of the free'end of the binder tape 21 in position for snap grippage againstthe underside of the flange 226 Y -When pressure on the grasp 3 is released said grasp will return to its normal position under recoil action of the springs 46, while the stepped ratchets I1, I8 having been concurrently rotated a definite degree, incident to the initial opening of the jaws .I, 2, a length of the binder tape 21 will have been drawn out sufficient to span the -J'aw heads 66, 96, or as indicated by the letter c in Fig. 30, in opposition to the stirrup-spring I asit discharges from the reel 23 under guidance of the tube 51 and stud-notches 58. The jaws Y I, 2 are now closed a second time which draws the length of binder c intervening the jaw heads 66, 96 snugly, as conventionally indicated by broken and full lines in Fig. 31, around the article a. Concurrent with this second closure of the jaws I, 2, the ratchets I1, I8 are again incrementally turned counter-clockwise by the pawling means 49, 56, 5|, with incidental forward projection of the flexible pusher 19 and the attached manipulator device |42, by operative coaction between the dogging claws and the engaged teeth of the ratchets I8, as clearly understandable from Fig. 9, more particularly. Movement of the manipulator device |42 initiatesl reopening of the trap-door device 236 by engagement of the tappetI56 with the lateral rod 236 of said Vdevice and closure of the binder tape narrowing levers |91 and 268 by respective co- "action of the rounded inner edges |86 of the spaced arms |48, |49, with the levercurvilinear offsets |85, and actuation of the levers 268 by aid of the rigid coupler rods 266; while the cutter member |46, due to the latched connection at |16, |11lis caused by its inclined knife edge |66 to shear-off the length c from the main bindertape 21 during the early part of the forward movement of the manipulator device |42, in order -to facilitate the narrowing operation, see Figs.

10 and 11. During-the further forward movement nof the manipulator device |42, the securing foil -mld-region of the crushed-in part of the binder tape 21 previously narrowed. by thev levers |91, 268; whereupon the compacting and foil severing jaws 2|6, 2II are respectively closed inward- `ly by engagement of the rounded lugs I5I and |54 with the cam projections 22 I, 222, as readily understandable from Figs. 20.` and 21 more spelc iiically, andhwhereby the bond is completed by Tange.

compact c'oiling fo'verlap fofthe tape 121 `and vstrip foi128.` Incidentally,1itis to vbe 4partic'zularly observed the inclined shearing edge 2|1 of the jaw 2|| coacts with the `sharp vc'o'nror-iting edge of the foil slot to effect a clean cut as readily Vunderstandable by those conversant with the-art. Furthermore, and as a result of this second 'closure of the jaws 2 with thefull forward movement of the manipulator device |42, the binder ribbon trap-door device 230 will be held open by the tappet |56 engaging the lateral `rod 236 'as shown in Fig. 11 and, as the manipulator device |42 is snapped back to normal position under the recoil action of the spring |69 by virtue of the latched connection between the parts |46 and4 |16, said trap-door device will be closed by Vrecoil action of its associated spring 231; Whereupon release of Ythe grasp 3 places thedevice in open position -ready for the'succeeding binder operation.

When it is desirable that the securing foil'band V281|, Figs. 28 and V29, be locked against accidental loosening, the claw2 lr6 Aof the spiralizing -jaw 2|!) is provided on its inner-face at the most desirable point with a barb or Vcutter prong 295 eective to pierce the overlapping ends 296, 291 of saidband and thus form an interlock298,as clearly understandable from Figs. 28 and 29, Awhereby a tight bond-about the Ynarrowed and compacted binder tape 21 is positivelyensured. It will also be apparent, without-further elaboration herein, -how vthe guard-215 and opposed flanking guards 216 jointly coact and support bundles l), by interlap- 4ping of their respective angular heads V8D and 292, as well as preventing objectionablelateral movement of such bundles during the-bonding operation. This adjunctive means is highly desirable When Yhandling plant stems and other bunched articles or things in restraining them=from falling in between and getting pinched by the confronting end Yfaces of the jaw heads 60, 96 during the closure operations.

Another advantage inhering to this invention is that packaged articles and bundles bonded by vthe means hereinbefore described can be nished off with a bow-tie, so 'prevalentik for fgifts by drawing out a su'icient length ofthe binder tape 21; then by disengaging the cutter member |46 from the manipulator device |412 by lifting 'the latch |16 with the finger offone hand inserted through the aperture 2199, said cutter 'memlber is retracted by the reco-il spring |169 out of operative Upon again closing the ljaws y|, 2 for the second series of operations, aboveful-l-y-explained, when the heads-66, S16-again separate-it will be evident that a further lengthof the binder tape `21 can be withdrawn land a "Vbow tied after the cutter member has been manually projected by the finger hold-|12 to sever the tape from supply. Still further, it will be apparent that multiple-winding of the tape 21 around the article a or bundle'b can be effected with -ease and facility by simply drawing out enough binder tape 21 to make the desired number `of 'wraps around the article, package vand so forth, land disengaging the cutter member-|46 as just previously explained. Again it will be likewise understood that when fresh supply reels 23, l24

are needed, the user simply lraises the lock pin 34 and draws out the arbor |-2 by aid of the finger hold 29 until said pin enters the hole 38 for removal of the reel V23, or enters the hole 39 V'for removal of the reel 24; vand obviously such Amovements will be reversed on lmaking replacements.

While one practical and preferred embodiment Aof thisinvention has Ibeen fully explained in connection with the illustrative drawings, it will be understood that vsaid invention is Vnot limited thereby but is capable of a variety of other mechanical expressions; and that changes may be made'in the form, details of construction and arrangement of par-ts without departing from the spirit of such invention( fore, tobe had -to the following claims for adenitionfof the limits and scope of the` inventive concept hereinbefore disclosed.
