BINDING AND CUTTING PLIERS Fil ed Nov. 9, 1925 5 Sheets-Sheet 5 o O o Patented Aug. 30, 1927.




Application filed November 9, 1925, Serial No. 67,978, and in France November 21, 1924.

My invention relates to pliers allowing Wires to be bound together, the bindings thusimade to be set and tightened round suitable-objects andfcut with a minimized expenditure in handicraft. Such pliers are .of great advantage :for setting up trelliswork'or for binding wires in reinforced concrete ,work.

My invention has for object pliers having two curved jaws one of which is provided with a longitudinal groove or channel wheretlirongh the wire canbe led without any jplay in 'one direction only, a blocking device preventing any backwarch movement. When the ;pliers are shut over" the object to a bind,- the wire passes beyond the grooved jaw and engagesithe other jaw. The pliers arethen slightly removed and the binding is twisted'and then out off bythe cutting device borneby the pliers.

These pliers can be provided with de' vices which ensure anautomatic and praca tical working. i

7 In some forms of executionthe pliers have only one vstem bearing the two jaws.

. This stem can show at one end a boX- containing aprovision of rolled up wire; This box bears a sleeve which can slide overt-lie stem making the wire .move along with it.

:An automatic 1 twisting device makes the stem of the-pliers rotate; this device can consist of a sleeve sliding in'a helical groovesuch 7 and a side view of tlie'rear partof a similar as isused in, wimbles or else the eccentrically disposed stem of the pliers can be vadapted to rotate like ahan d brace.

The cutting devices according to .myin vention are of several kinds. They are either provided by the tempered edges of the jaws themselvesor else disposed at the end of air-independent lever-pivoted to one of the jaws, said lever engaging said jaw and urged backby a spring into itsnon-operative position. WVhenthe grooved jawis pivfiotally secured tothe stem .ofrthe pliers, the cutting device can be-provided by a sharpened edge of the groove wall cooperating with-asharpehedpart {of thestem, these sharpened parts being afi'orded'by the parts "ofthe-stem andofthejaw whichslide one upon the-other.

A number of devices have also been. pro- 'vided for controlling the movement ofthe wire in i the groove, It may: consist .in a

' {wedge actuating a't'oothed partwhich urges disposed inya. groove. which isv oblique-with the wire along-, ,or elsea springmrged-ball twisting tool.

wedged when the wire moves in one direction and s uiiwedged when it moves in the reverse direction. The control of the wire can also be affected by a series 'ofballs disposed round the wire in'a conical frame which can be wedged inside a conical housing or again by pivoting spring urged clamps which are caused to open when the wire moves in one direction and to close when it moves in the reverse direction.

Several forms of construction, simple and Fig. l'is a cross section of small pliers as used for securing 'WII'BWOlk to wires stretched between poles.

Figs. 1, 1", 1, 1 show diagrammatically 'how the pliers work. v

Fig. 2 shows similar pliers, a little larger,

as used for instance for binding the reinforcement in concrete work.

"Figs. 3 and 3 are longitudinal sections respectively of the rear and of the front part of pliers provided with aboX for holdin'g'the roll of wire and the jaws of which areadapted'to'meet at their outer end at a point not inaliglimenbwith the stem of the implement. x

Figs. 4 and '5 are similarviews of the front part of thesame-tool wherein the jaws Figs. 6 and 6 are longitudinal sections respectively of the rear and ofthe front part.

of a ditfereiitform of execution of a wire Referringto Fig. l, the'pliers comprise two aws 1,"2pivotally secured one-to the other and disposed at the end of the arms 1,

2. The jaw'l and. the arm 1 areprovided with. a longitutlinal groove or channel 3 wherethrough the wire 4 can move. The jaw-2 shows a hole 5; the respective edges 6 and 7 of the two jaws are tempered so as reference to. the wire so that the ball is tose rve' "for cuttingtliewire. .The blocking device comprises asp ring 8 disposed" in a groove .9 -and urging'the ball 10 obliquely against the'wireit. The device which controls the movement of the wire consists of a wedge ll which can move between the stops l2, l3. The slanting side of this wedge pushes the toothed part Ll no as to melee it: catch in the wire l when the wedge ll. is pushed in the direction oi? the arrow 'lhc pliers work in the following manner: the wire 4-. being passed through the groore 25 :lor instance until it arrives against; the edge ti oi? the jew, the pliers are CllSpOSQCl (llig. 1) over the rods which are to be bound together, the wedge ll being pushed in the direction of the arrow The wedging oi? the said wedge 1.1 makes the toothed part let end thercbj the wire l advance. When the. wedge ill has come against its; stop 13. it is brought bacl; again. During this backward movement it. does not carry the wire back with it. on one hand becauee the wedge ll actuating: the toothed port 1"}: unwedded and secondly because oi the action ol the blocking ball 10. 'lhus the wire l. protrude}: by an important length beyond the jaw l. and pae ca through the hole 5.3 of the Saw 2. The jaws of the pliers are then opened (Fig. l") and moved backwards so an to slide along: the wire. Once rods 15 have been paused (Fig. 1") the pliers are slightly closed without being; tightened over the wire. The pliers are then rotated (Fig. 1) so as to twiet and to tighten the binding. Lastly (Fig. l) the two jaws are closed tightly over the wire so as to make the edges 0. 7 out the binding which is thereby finished, whilst the pliers are ready for making another binding.

In a general manner, the pliero shown on Fin. 2 worl: exactly lihev the pliers shown on l. 'lhe main dillerence resides in the device :l'or moving; the wire Forward which comprises like the blockin device a hall 1.6 urged by a spring il'i' agoi t the wire. llhe eprinp; 1? is disposed in a groove 18 provided in a head ll) scoured to a elecro 2O Sliding over the corresponding arin oi? the pliers. lhe nnwenient oil the sleeve E20 in the direction of the arrow f. will evidently wedge the ball :in einst the who the reverse movc lnent; uilwedgingj it.

in the plier; shown on l igs. ii and 3 the two tll'lllb are replaced by one only stein ill cent with one of the j aws whi the other jaw 23 is pivoted to the stem; the closing of the pliers is ensured by a spring 2- which ur e the jaw 93 tightly against the jaw 22. Orer the end oi the stem 21 is mounted a sleeve which can slide along the said stein. To the sleeve is secured :1 box 9-6 containing a spool Ii round which a supply of wire 28 is rolled. The movement oi the wire is controlled by three balls :29 disposed at 120 one -lroin the other round the wire and one of which only is shown on Fig. 3. These balls are disposed in a conical frame 30 urged by the spring 31 into a conical housing; 82 screwed on the end of the box 33 and occurred to the sleeve 25. It is easy to see that he balls 23) cannot prevent the Wire from advancing in the direction of the arrow 9 as this motion of the wire would unwedge the lieverscl the balls will prevent the :tia oi spool 28 from urging the wire burl; as; this would wedge the balls into the 'iical recc The supplementary block- .g device at is built hire the just. described controlling device.

llhe stem 21 and the. jaw are constituted by two stamped. inetal sheets and are provided with a tubular casing 35 showing a projection 36. This projection acts as a stop for the tuljiular handle 3'? wlien latter is moved baclcwarltle. in View ()l T :tacilitating the opening; oi the pliers, the jaw .23 is pro ridcd with a. lever 38 which can be actuated by the forefinger of the hand holding the handle.

in these pliers, the wire is twisted by the mere rotation oi. the tool instead of by hand. 'l or this purpose the stem 21 is not in uligrn ment with the outer end oi the jaws so that the binding; may be twisted by rotating the tool round a line joining; the outer end 01 the clewd jaws with the end of the stem which in the 'larthcst tl'roni the awe. In the pliers til ehown on Fine. 3 and 3, the wire is cut by an auxiliary lever 39 pivotallr secured to the jaw 12 4-0 and cutting edge ill. oil. which comes against the cutting edge 42 of the jaw (these cutting edges are shown on drawing as provided on special tempered steel parts). .s'l spring 4- holds nornnilly the lever 39 in its nonoperative position adjuetcd by means or the eorew ll. It one to see that the \i'orlring ot the pliers very similar to that, oil the tool shown on l ig. l. but much simpler. lhe pliers:v are held by their tubular handle All" and the jaws are opened by the forefinger actuating the lever 38. The parts to be bound are passed between the jaws whereupon the lever 38 being released, the pliers are closed. The wire is caused to advance by the requ red length through a. suitable number ol to and fro niotionaolf the tubular handle 37 which drown along in its: operative direction the balls 99 and makes the wire a .lvancc. 'lhc je s": are then again reopened and the parts to be bound now partially surrounded by the wire paeeout, oi the said jaws. The stem is then rotated so to tighten the binding. other which the wire cut by the lever 39. The pliers are easily removed by actuating at: the same time the lever 38.

The pliers allow a very short. binding to be made which broken oll' near the third winding. In VlCW oi, this it; is sufilcient to bend over slightly the wire projectingberend the jaw 25) just: before the wire is twisted. It cannot. slip any more and the wire breaks oli automatically.

The pliers shown on Figs. d, t, 5, and 5 are quite similar to the one just described and differ only by the twisting device which com prises a helical groove provided on the stem 21 and cooperating with a nut 46, this device being similar to and working like the sleeve of a wnnble.

The pliers shown on Figs. 6 and 6 are automatic like those shown on Figs. 4 and 5. The difference with latter lies mainly in the advance and cutting devices. The advance device comprises the clamps 47 pivoted at 48and urged back into their closing position by the springs 49. The wire is held tightly between the ends of the said clamps. Evidently if the sleeve is pulled in the direction of the arrow h the wire held by the clamps videdwith a longitudinal narrow wire re-v ceiving channel continuing that of the said 47 will be drawn along and will not be allowed to move backwards because latter movement would increase the hold of the clamps on the wire. As shown, the blocking device 50 is similar to the advance device. In these pliers both jaws 51 and 52 are pivotally secured to the stem 53. They are closed by means of a sleeve 54 urged by the spring 55. In the part where a pivot ing surface of thejaw 51 slides along a pivoting surfaceof the stem 53 the groove 56 shows sharp edges 57 which can engage the sharp edges 58 of the part of the groove provided in the stationary part of the pliers.

It is easy to seethat the opening or the closing of the pliers willv automatically make the sharp edges'57 move with reference to the sharp edges 58 and thereby cut the wire; It should be noted that in the pliers shown the groove 56 is continued in 59 in the other jaw 52. Latter jaw has been thus recessed in order to let the end of the wire enter it.

, Except the automatic cutting, the last described pliers work exactly likethose shown on Figs. 4, 4 5, and 5.

What I claim is: V 1. In a wire working tool the combination of a channelled wire receiving jaw, the channel in the said jaw having a diameter very slightly superior to that of the"wire, of a stem bearing the channelled jaw and prochannelled jaw of a second jaw recessed at its outer end and cooperating with the channelled jaw by closing over the parts to bind, of a box communicating with the rear of the channelin the stem, for receiving a roll of wire, of a device adapted to cut the wire at the end of the first named aw, of a blockin device preventing any un esirable rearwar motion of the wire and of m'eans whereby the forward motion of the box causesthe wire to advance. Y

2. In a wire working tool as claimed in claim 1, means whereby the wire-holding 7 box is'slidably secured to the rear of the channelled stem.

3. In a wire working tool the combination of a channelled wire receiving jaw, the channel in the said jaw having a diameter very slightly superior to that of the wire, of a stem to which is rigidly secured the channelled jaw and provided with a longitudinal narrow wire receiving channel continuing that of the said channelled jaw, of a second preventing any undesirable rearward motion of the wire and of means whereby the forward motionof the box causes the wire to advance- I Y 4. In a wire working tool as claimed in claim 1, a sleeve sliding over the stem and to the rear of which is secured the wire containing box, a rearwardly conically recessed part securedmside the sleeve, a rearwardly conical'frame secured inside said recessed part and a series of balls in said frame frictionally disposed round the wire.

5. In awire working tool as claimed in claim 1, a sleeve sliding over the stem, and to the rear of which is secured the wire containing box, a rearwardly conically recessed part secured inside the 'sleeve, a rearwardly conical frame secured inside said recessed part, a series of balls in sald frame frictionally disposed round the wire and said blocking device comprising a second series of balls disposed round the wire, a conical frame wherein the last mentioned balls are lodged and a conically recessed part atthe rear side of last mentioned frame and. secured inside the stem. I

6. In a wire working tool as claimed in claim 1, a sleeve sliding over thestem, to the rear of which is'secured the wire containing box andadapted to draw the wire along with it, atubular handle disposed round the I stem and over the sleeve and the rear part of'which is secured to the box,a projection on the stem acting as a stop for said handle and a spring urging the recessed jaw pivotally securedto the stem.

In testimony whereof 'I affix my signature.
