APPARATUS FORv BINDING PACKING CASES AND SIMI LAR OBJECTS BY MEANS Oil HOOPS.

Application filed June 11, 1928, Serial No. 284,564, and in France May 14, 1927.

It is the usual practice, .in order to strengthen packing cases or to render them free from the possibility of damage or for contrary, it has not hitherto been possible to produce an apparatus which will allow of carrying out the various operations necessary. 'lhus such operations usually are carried out by means of three independent mechunisms; a tensioning apparatus by means of which the necessary tension is given to the hoop, an assembling apparatus which allows of joining the two ends of the hoop, and

shea rs tor-cutting the band of hoop-iron after such assembly has been effected.

The present invention relates to an apparatus for stretching a metal hoop and comprises a tightening roll, means for applying one .of the ends of the hoop to one of the peripheral points of this roll, means for applying to the roll at a different point on its periphery, a. part of thesame band forming the other end of the hoop .to be formed. and means for turning the roll about its axis in one direction only, so as to impart, by this rotational movement of the roll. displacements to the two ends of the band in different direetions zmd thus to stretcher tighten the same on the articles to be bound. I

The present invention also relates to an apparatus for carrying out all the operations required in binding, i. e., tightening the band, assembling, with or without clamps, the free end of this band over the other part of the band fedtowards it, and cutting said band. Further all'the-se operations are carried out by means of a single operating lever. As

the attendant does not releasethe-lever during these operations he can consequently rapidly bind cases and bales of all types.

The accompanying diagrammatic. drawings are given by way of example and are not to be taken as in any way limiting the scope of the present invention.

Figure l is'a view in elevation showing the method of using the apparatus.

The same reference numerals indicate the Same elements in the various figures;

In Figure 1 the binding machine A is shown above a halo at around whichis a metal band I) from a drum 0. The free end (1 of this band is engaged by the'maohine A and the portion 6 also passes through this apparatus after h: ving passed around the bale a.

By means of the machine A which has just been described, the band passed around the bale is first tensioned and then the two ends (1 and e are brought together by means of a clamp f, the band. remaining stretched, and

finally the portion e is cut and separated from the drum 0.

The clamps used for this union of the two ends of the bandconsistofametalplatewhich is preferably previously pierced by a hole 9 Figure. 2. The sides k, z of this plate are bent into the form of a U (Figures 3 and 4). A clump of this shape is introduced into the machine A which, when the band is stretched around a bale, forces the sides h and i against the Walls (1 and e of this hoop Figures 5 and 6, widens the opening 9 of the clamp, perforates the ends (Z and e of the hoop and at the same time seals the ends (1 and 0 together and with the clamp f Figure 6, the sides of the opening g of the clamp being forced into the openings provided in the ends (1 and e and thus.

preventing any slipping of the end d relative to the end e. As soon as this has been done, the end e is cut off and separated from'the drum by means of the same apparatus.

The binding is then completed and the apparatus A can be withdrawn.

The invention isof course not limited to an apparatus A adapted solely for use in combinaiton with clamps of the shape shown in Figures 2 to 6. Clamps of other shapes or type may also be used and the apparatus can be adapted to the shape selected. The apparatus can also be simplified in order to produce hoops, the two ends of which are to be superimposed without a clamp by. any suitable means. Similarly hoops previously cut to the correct length can be used and the cutting mechanism can be eliminated.

The following description refers to a complete apparatus which allows of carrying out all the operations described above. This apparatus comprises a base on which are mounted A tensioning apparatus which allows of stretching the hoop over the object ,in question as tightly as necessary,

A mechanism for closing a clamp placed over the tensioned hoop,

A mechanism for binding the ends of the hoop together, 1 i

An apparatus for cutting the hoop, and preferably, a single lever controlling all such mechanismsp In the example shown in the drawings, the mechanisms are all mounted on'a base 1 pro-'- vided with a handle ,2 adapted to facilitate the operation of the machine. r

The single lever 3 is connected with the four mechanisms mentioned, so that a to and fro motion imparted to the lever through a given angle causes the functioning ofathe' tensioning apparatus alone, the other mechanisms remaining out of action, whilst dis-. placement of the same lever through asec- 0nd angle forms the clamp,' a.nd displacement through a third angle brings the ends of the hoop together and cuts the end of the hoop connected to the feed drum.

Tensiom'ng mechanism.

The tensioning mechanism comprises a roll 4, Figure 12, arranged at one end of a spindle '5 which carries at the other end a ratchet 6 I actuated by a pawl 7 mounted on the lever 3. The pawl is held-permanently against the ratchet '6 by means of a spring 8. .The

. lever 3 rotates "on a sleeve 9 carried by an element 10 mounted on thespindle 5 and provided with a sector 11 acting as' guide for, the lever. i- 1 A pawl 12 bearing against the ratchet 6 under the action of a spring 13 anchored in the base 1 of the machine prevents any return movement of the ratchet 6. p The element '10 is itselfmovable about, spindle-14 mounted on the base 1, Figure 7 position,

between two bosses arms 19 and 20 of the of the band ends as hereinafter described and swinging of the roll into tensioning the bosses hold the band ends against portions of the roll substantially diametrically opposite to each other.

The lever 3 is boss 21 adapted anisms andv also described.

The clamp closing mechanism Figures 8, 9

and 10 comprises twolateral levers or jaws 22- .Figure 10 articulated on spindles 23 mounted on the base 1. The lowerportion of each of the jaws is provided with a hook 24 and notch 25. On closing the jaws 22,-the hooks-24 force the two arms hand i of the clamp against thetwe ends dand e of the band '6 and these arms thus turned are held inthe twonotches 25 in these jaws.v Each of the levers 22 is alsoprovided with an inclined ramp 26 arranged opposite a similarramp 27 on one of the arms 28 of a bifurcate member '29, mounted on a sleeve 30 enclosing a spring 31 and located opposite .an abutment 32 provided on the base 1. This sleeveis also provided with an abutment 33' mounted opposite the boss 21 on the lever 3.

Springs 34,}i1iounted between the jaws 22 and. the base 1, keep the jaws open under normal conditions.

Under these conditions, when a thrust is i b'rought to bear on the boss 33-by meansof the levers 3. throughthe boss 21, the ends 27 of.

It is provided with an provided with a V-shaped the arms of-the bifurcate member-29 causev and consequently close hoop band.

ball bearings 35 which can be inserted between the jaws 22 and abutments 36, pro-fi vidcd on the sides of the base 1.

Ill echam'sm for uniting the ends of the hoop. i QThe uniting mechanism Figures 8, 9' and" Thisrod is co-axial withthesleeve '30 and acts as a guide for the latter. It is provided with a shoulder 44 abut- Mechanism for cutting the hoop.

The stamp 38 is provided with striker-49, arranged above one blade of the shears 50 carried by the jaws 22 of the mechanism for closing the clamp, and actuated so as to bite into the end e of the hoop on completion of the punching operation so as to leave the end (Z intact. The force of the blow, and the position of the eccentric 48, are to be so regulated that the blade 50 will just shear band end 0 without penetrating into band end at. It is not essential that the shear of band end 6 be absolutely complete as the fact that portion e of the band is already under tension tends to tear the band when artially severed. Furthermore, as hereina ter set forth, the swinging away of the tensioning roll tends to pull on band a where it is engaged with the same, thus to tear band e at the portion where it has beensubstantially severed by blade 50, if the tension on the band has not completed the severance.

The blade 50 of the shears slides in a guide formed in the lever 2 and is held in place by means of the key 51.

This blade 51 cooperates with a shoulder 51' integral with the blade 51 acting as an anvil during the cutting of the hoop.

Finally

rollers

52, 53 which guide the hoop are inserted in the base of the apparatus,

Operation.

The apparatus held by the handle 2 is placedv in the correct posltion on the article to be bound, for example .a packing case, at the point where the binding is to be formed, Figure 1, the actuating lever 3 being left free. The jaws 22 are then held open by springs 34. The spring- 45 maintains the punch 37 in its raised shears 50 free. I

'The end 0 of the hoop 6 carried by the reel 0 is passed over the roll 4 between the latter and the upper boss 17 of the base 1. For this purpose this roll carried by the

members

10, 11 isheld away from the base 1 by the springs 15 until this element just abuts against the base 1, Figure 11, at the point 54, and this end e of the hoop is passed below the

rollers

52 and 53. and then below the jaws 22 (during this adjustment the operator bears slightly on the handle 2). The band I) is then wound round the case a and the end is position and leaves the passed below the apparatus under the roll 4, between the latter and the lower boss 18, and then again below the jaws 22 until slightly beyond the same Figure 1).

At this moment, t e operating lever 3 is moved in the direction of the arrow in Figurel. The friction of the lever 3 on the

element

10, 11 wedges the roll between the two ends d and e which then bear against the bosses 17 and 18, so that by giving the lever 3 to and fro movement through the angle a. the pawl 7 acts on the ratchet 6, turns the roll and causes the two ends (23 and e to move in opposite directions thus tensioning the hoop about the object a. The pawl 12 prevents the ratchet from slipping back. As soon as the tension has reached a 'suflicient value, the lever 3 is returned to its position of rest and a clamp f, Figures 3and 4, is passed between the jaws 22 up to the cutter 50.

By displacing the lever 3 through the angle 3 toward the handle 2, the boss 21 being then in contact with the boss33, the

element

28, 29, 3O slides between the jaws 22, closes the lat-- ter and consequently forces the arms h and i of the clamp against the hoop; then continuing the movement of the lever 3, so as to move it through an angle a, the connecting rod 42 actuates the

levers

40 and 41, and the stem 38 and the punch 37 are lowered and punch the two ends d and e, uniting the latter together and with the clamp f. The hammer 49 then strikes the blade 50 which cuts the band to the rear of e only, the band d remaining intact. The sealing pressure is maintained by the lower portions of the levers, and the cutting pressure by the shoulder 51'.

It is to be noted that, shortly before reaching the end of its movement, the lever 3 contact-s with the abutment 16, becomes integral with the element 11, and its short arm is reduced to the distance 55 separating the axis 14 from the boss 33, so that this lever transmits a powerful blow at the momentof cutting the band. At the same time the roll 4 disengages from the band d and the pawl 12, and due to its biting into the upper band, tends, as it swings away, to carry the upper band with it thereby tearing the band at the portion substantially cut through by the blade 50, in case the blade has not entirely severed the tensioned upper band, as set forth above.

In order toremove the apparatus it is sufficient, after having pushed the lever sufficiently back, to'lift the punching end of the device off of the band joint, and then (as the tensioning roll is already disengaged) to push the entire apparatus sideways to slide arm 20 from beneath the band d.

In the apparatus described above and shown in the accompanying drawings, it has been supposed that a single level-3 actuates all the mechanisms carrying out the various present invention, an apparatus can also be constructed which allows of carrying out the same operations by means of a plurality of separate levers, each of which is adapted to carry out one or more of these operations, which levers are actuated successively in desired sequence.
