Specification of Letters Patent.

Patented May 27', 1919.

Application filed April 16, 1917. Serial 110,162,321.

be connected to each other to close the tie.

The invention consists of the construction of the tool as described and pointed out in the claims and as illustrated in the accompanying drawing in which:

Figure 1. shows a side view of the tool as it appears at the beginning of its manipulation.

Fig. 2. shows the opposite side of the tool with the manipulation progressed to a point ready for starting formation of the twist.

Fig. 3. shows the'tool as it appears when viewed from the right side as it is shown in Fig. l or from the left side as it is shown in Fig. 2.

Fig. 4:. shows the tool as it appearslwhen viewed from the left sidein Fig.1 or from the right side in Fig.2.

Fig. 5. shows the lower end of the tool as it appears inFig. 2. V

Fig. 6. 'in a similar'view shows the tool in a position with the manipulation progressed for the purpose of forming the twist.

The tool is of the plier type and consists of two lever handles, curved as shown and pivotally connected to each other between their ends.

Characters A and B designate the levers proper which at their free ends engage the wire and serve for twisting the same.

They are pivotally connected to each other at 10 and are, extended beyond their pivotal connection where they form the complementary handles a and b. 1

Each lever is provided at its free end with a shoulder, numeral -11 designating the shoulder on lever A anolnumeral 12 designating the shoulder on lever B, said shoulders being on'opposite sides ofthe tool and projecting in opposite directions from the plane in which the lever'handles move on each other in their pivotal manipulation.

A clamping dog 13 is hung to lever A above shoulde 11 by means of a pivot 14. A similar dog 15 is secured to lever B above shoulder 12 by means of a pivot 16.

Each of these dogs is provided with a serrated edge and actuated by a spring 17 whereby these dogs are pushed toward the shoulders above which theyare positionedso as to causethem to-engage-the ends of the wire tie and to clamp them against said shoulders opposite them as shownin Figs. 1 and 2.

Normally however these dogs are above clamping position being held out of action by springs 18, 18 when bearing into notches 19, 19cm the dogs as shown in dotted lines in, Fig. 1.

n The wire used for the ties might be in pieces of given length for particular cases and to be affixed at their ends to the ends of levers A and B for closing the tie and for forming the twisted joint thereof.

A more practical way however is to take the wire from a reel supported at suitable height above the floor or' a bench withthe tool hanging toa part of unreeled wire.-

Forsuch purpose guides in form of eyelets 20 and 21 are provided on one of the lever handles and a clamping spring 22' is also provided under which the wire is passed and which bears with sufficient pressure against it, to prevent the tool from slipping ofi'. I p I Under this arrangement the tool is used as follows: I

Wireis pulled off the reel andthrough the tool until sufficient'of it to formthetie is clear of the tool.

This stretch of wire is now passed around the bundle or package F to be tied as shown in dotted lines in Fig.1 and the free end C of the wire is passed in over shoulder 11 as shown in Fig. 1 and'dog 13 is pushed to the right by action on athumb piece 23 on it whereby'it is released from spring 18 and subjected to action of spring 17 which causes the serrated edge of the dog to impinge on the wire so as'to clamp-it against shoulder 11. v a p On account of lack of sufficient space,,the

bundle is shown out of proportion and should appear larger.

The wire at D is now pulled up against bundle F and drawn over shoulder 12 on lever B and by action on it in the direction of the arrow (Fig. 1) as much of the slack as is possible to do by hand is taken out.

The wire is now held to the point to which it has been pulled by being attached to lever B, this being done by clamping the same against shoulder 12 by means of dog 15 above it as shown in Fig. 1, this dog being manipulated and held in a manner similar to the manipulation of dog 13 and by means of a similar thumb piece 23 on it.

l/Vhile this is being done the tool is open, that is its levers are apart as shown in Fig. 1 so that when the tool is now closed as shown in Figs. 2 and 5, most or all of the slack still in the tie to be formed is taken out of the wire before the joint is made by twisting the wire portions C and D about each other as indicated in dotted lines in Fig. 2. I

For the purpose of forming this twist, the tool is rotated about itself as shown in Fig. 6 (note arrow) which shows the beginning of this part of the manipulation.

Preceding this twisting manipulation however and while the tool is being closed up as shown in Fig. 2 preparatory therefor, the wire beyond portion D which is to be one of the ends of the tie, is cut off by a cutter 24, thus severing the wire to be used for the tie from the reel wire, the latter springing away at the point of separation, note Fig. 2, said cutter moving against the wire and against a lateral extension of shoulder 12, it being also guided in its movement in a corner formed by a flange 25 and a lateral extension 26 of lever B.

This action of the cutter is produced by a cam 27 on lever A which, when the tool is being closed up as shown in Fig. 2, moves against the upper end of an angle lever 28 and forces the lower arm of the same which carries cutter 24 down against the wire.

This angle lever is pivoted to lever B and by preference pivot 16 which supports dog 15 is used for the purpose.

The co acting members 27 and 28 are so arranged and shaped that the movement of the cutter for cutting is completed before the tool is entirely closed up.

When the tool is opened again as shown in Fig. 1, cam 27 tends to move away from the angle lever which is now moved in opposite direction by a spring 29 which may be attached to flange 25 and whereby the cutter is raised up from shoulder 12 so as to be out of the way when wire is to be passed in again for another tie.

After the twisted joint has been formed the tool is disengaged from the tied wire by releasing the wire ends C and D from the dogs for which purpose these latter are pushed outward by action 011 thumb pieces 23 as shown in dotted lines in Figs. 1 and 2.

Ordinarily this cannot readily be done with the fingers because the wire ends stick rather tight between the dogs and the shoulders below them, the close engagement being due to the pull on the wire ends when the twist is being formed and which causes the serrated edges of the dogs to bite into the wire.

Therefore mechanical means are provided in the form of release levers 31, 31, one of which is pivotally mounted at 32 on the flat side of each lever handle.

The upper portions of these levers form handles and are held in position ready for operation by springs 33, 33 connected to flanges 34, 34 formed on these handles and positioned between these flanges on the handles and the edges of the lever handles.

The lower ends of these release levers terminate opposite the thumb pieces of the clamping dogs and normally occupy a position out of touch with them in which position they are held by springs 33, 33 and against stop pins 35, 35.

When the time comes for disenga ing the tool from the completed Wire tie, the hand which holds the tool simply grips also the upper ends of these release levers and by tightening the grip, said levers are compressed whereby their lower ends are caused V to move against the thumb pieces as shown in dotted lines in Fig. 2 thereby releasing the dogs.

In eitherevent this action on the dogs is of sufficient extent not to merely release them, but also to move them so that notches 19, 19 on them pass within action of springs 18, 18 permitting them to engage the dogs and to hold them thereby impositively out of the way so that the tool is always ready for insertion of the wire for the next tie to be formed.

A stop 36 is provided to limit the opening of the tool as shown in Fig. 1. I

One of the bosses or projections provided on the levers as a means for attaching springs 17 and 18 which actuate the clamping dogs may also serve for this purpose. 7
