will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to wire straightening and deforming machines, and has for its object to provide a mechanisml of this na-v ture which will he simple in construction,

comparatively inexpensive to manufacture,A

and more eiiicient in use than those which have been heretofore proposed.

lWith these and other objects in view the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claims.

In order that the precise invention may be the more clearly understood it is said z-Machines which require straightened lengths of wire with which to band packages are well known. These machines usually secure one end of the straightened wire in a slotted post, While tlie'hight of the wire is passed around the package and returned back to and beyond said post prior to the tensioning and wire twisting or tying operation.

Machines of this character having wire holding posts whose slots are of a less width than are the diameters of the wires Ato be used therein are also now known. In these last named machines, invented by us, the Wire is deformed, or flattened, near its extreme end leaving a shoulder at each end of the flattened portion, so tlfat said attened portion may readily enter the said last named slot, and the wire he held by the shoulder at .the

. outer end thereof.

The attening of wire ends are not only troublesome, but should the operator take hold of the wrong end of the wire he is put.

to the annoyance of turning it end for end.

which takestime and lowers the efliciency of machine.

The purpose of this invention more speciiically stated is to provide a means for automatically flattening both ends of the straightened lengths of wire, and to atten to the same degree wires of different sizes so that they'may lall be used in the 'same machine without having to chan/ge 'the wire'V holding post.

A further object of the yinvention is to pro! vide the trade with straightened lengths of wire difierin in size, yand having each end iiattened or t eiormed to a uniform crosssection, al1 as will hereinafter appear.

Referring to the accompanying dravvingsV forming a part of this specification in which like numerals designate like parts inall the v1ews:-

Figure 1 is a side elevational view of a straightening and deforming machine made f in accordance with this invention;

Figure 2 is a plan view partially in seci* tionof a portion of the parts shown in Figure 1; Figure 3 is a sectional 4view taken on the. v'line 8-3 of Figure 2; .I

tially in section of the extreme right hand end of the machine as seen in Figure 1; and

Figure 9 is a view of a Wire holding. ost adapted to receive deformed wires of di erent sizes.

1 indicates any suitable frame work on which is mounted a power pulley 2, having a shaft 3 carrying a driving friction disk 4, engaging the driven disk adaptedto rotate the change gears 6 and 7, all as will he clear from Figures 1, 2 and 6.

Surrounding the power shaft 3 is a sleeve 8 capable ot being connected to and discon neeted from said pulley 2 bythe vclutch 9 operated by the arm 10,' carried bythe rod 11 having the arm 12 rotated byA pin 13 on the gear 14 meshing with the pinion 15 i mounted on the shaft 3 and continuously rotating with said friction disk 4, all as will beV clear from Figure Q. Mounted on said sleeve S and rotating therewith is the cam 1601i' which rides the roller 17, mounted on the bracket 18, rigid with the housing 419, in which the change gears 6 and 7 are mounted.

.the disk 2V to As is best shown in Figure 5, said housing 19 together with said change gears 6 and can be raised around the shaft 2() as a center Whe-n the eain 16 lifts said housing by reason of its Contact with the roller 1T.

It will now be elear that as thev pulley 2 and shaft 3 `i,ontinuously revolve, the sleeve 8 will be intermittently driven from said pulley and the cani 1li will intermittently raise and lower said housing' 19 on' its pivot 30 and thus disi-onneet and connect at predetermined intervals the frii-tion disk 5 with the eontinuiiusly rotating driving di.,\' fl. lt will further be cleary that. during said ionneetion the driven disk will rotaie the change gears 6 and T and the shaft 2l), while said parts will he idle during the periodsl of disconnection.

The Wire 2l to be eut into lengths and whose ends are to be deformed, is unwound from a reel not shown` is then lead l'ietween the two sets of 'straightening rolls 22 and 23, disposed at right angles to each other` and is then lead over the wire driving disl' 24 mounted on the shaft 2() which interinittently drives or feeds said wire forward a distance depending upon the speed of rotation of said shaft which is governed by the speed changing gears and T as will be readily understood. ln order to m'ake positive the. feed of the wire 2l the disk 24 is grooved as liest shown in Figure t5, and a correspondingly shaped disk 26 mounted on sha-ft 27 rotated by the gears 28 mesh with the gears i", lits said groove and forcibly moves said wire, forward whenever said gears T are rotated. Said gears i' and 2S arcl only very loosely ineshed together illus trated in Figure o, so that the screws 3() may adjust the shaftl 2T up and down to cause grip wires of different gages.

Also mountedon the sleeve 8 is a pair of eains ll and 32 respectively operating the rollers 33 and 3l carried by the arms 35 and 5G respectively ipivoted -as at 3T and 38 as shown. f'

The lever i'airies the Wire deforniii'ig and cutting jaw 4() while the lever 36 carries the similar jaw 4l. Thatis to say, as will he elear from Figures 2 and 4, the jaws l() :ind -ll are provided with deforming dies 13 each provided with de-forining members a uil ruttiiig members 4G. so that when a pie`- determined length of wire is forcibly fed bet een said liaws and stopped byreason of the disks 4 and ,having been disengaged said jaws 110 and 41 will be brought together by the eanis 31 and 32 with the result that the wire 21 will not only be deformed but will also be out in two as indicated in Figure 4.

Before the wire deforining operation linst described takes place, the extreme right hand end of the wire as seen in Figures l and Q will have passed to the left hand end of the'fluted revolving drum ,50 provided with wheel 5l. shaft 53 memes the gear 51 meshing with the toothedv Wheel i 24 and 2H it occupies one of the grooves in the drum 5l), andvwlien it is severed by the means disclosed the pin 55 will turn the wheel 52, and drinn 50, so

wire after having fallen into the trough underlying said drum 5() is swept out of l'luted members of sa'd drum, and is caught on the curved arins mounted on the sha ft (Si) carried by the frame 61 supporting said drinn 50. At the end of the drinn 5t) is a counting device o2 provided with a pin 70, see Figure 8i taking against a lever 71 pivoted at T2 having a dog' taking in a slot T4 i-:irried by a disk 75 mounted on the shaft (3U. and thus preventing said shaft and arnis 59 from turning. v

When a predeterniined number, sayi'25U. of said severed and straightei'ied lengths oi wire. have, however, fallen onto said arms 5S), the. pini() will lift the. dog T2 and permit the weight of the bundle of wires to turn said arms 59 and shaft (5() so that the bundle will roll out onto the erai prepared for shipment.

'l'he operation of this machine willy be rleai' from the foregoing but may be brieiy summarized as foilo\vs:--

that said severed Iower being applied to the pulleyvL-the shaft il is rontinuously rotated whichimparts motion to the friction disks4 and 5, to the change gears 6 and 7, the shaft' 20 and the gi'ooved wire feeding disk 24. Said po\\'el\also imparts motion t() the gears 28, shaft 2T. and wire feeding disk 26, fitting the groove in the disk 2l. When Wires of different sizes are to be deformed in this maehine` the screw mechanism il() is adjust- .ed so that the disks 24" and 2l will properly grip the wire whatever may he its size and thus insure that it is positively fed through the niaehine.

Mounted on the power shaft Si is a Sleeve H which through the cam lG and roller 17 turns the change gear housing 19 together with the ihange gears anddisk 5'011 the shaft 2t) as a center, and thus at each rotation of said sleeve disengaged Afrom the friction disk 4 so that the feeding operation is stopped only to be started again when the cam l1G has disengaged the roller 17 and the disk 5 has reengag( d the disk 4. Y -v l'liis said sleeve 5 receives its motion from shaft Il, by reason of a pinion 15 mounted thereon engaging the gear 14provided with the pin lil eoacting with the arm 12, shaft 1l. and army 10 to intermittently engage the clutch member 9 with the hub of the power pulley 2.

lle (34 ready to be the same liy one of the lll H. the friction disk 5 is izo That is to say, it will require a plurality of. revolutions of the power shaft 3 to produce one revolution of the sleeve 8, and thus will there occur a plurality of revolutions 5 of the feeding disks 24 and26 to each revolntioii of the power shaft 3. It is evident that h v changing the speed of the shaft 20, by suitably manipulating-the change speed gears 6 and 7, the speed with which the 10 wire is fed will also be changed, and therel forward b fore, with a steady rotation of the pulley 2, different lengths of wire 2]. may be f ed the disks 24 and 26 at will.

The sai wire 21 is thus positively fed 145 forward into one of the flutes of the drum whereupon .the feed 50, and above the holding tray or member 58, until the feeding means is thus stopped.

ln this manner is a predetermined length of wire antomaticallyefed into the tray 58 ing stopped it 1s antoinatically deformed and severed in a manner now to be disclosed. That. is to say,

- the rotation of theI sleeve 8 causes the cams 25 against 'a bight o 30. wire severed midway between said depres- 31 and 32 to brin the deforming dies 45 the wire, 'thus forming `fiat depressions 80 therein, havin the abrupt shoulders 81 at the endsV o said depressions and simultaneously with this deforming action is the said bight of the ,sions as indicated at 82, Figure 4.

It thus results that one end of the severed A length of the wire is deformed in the iiianv ner disclosed while 'the other end of the oncoming wire is" likewise deformed with the result that when the bight of the oncoming wire is severed the finished length of wire will havel both ends deformed as is best illustrated in Figure 4. It will therefore he clear that when one uses a length of wire deformed at both ends'in a manner disferent sizes he will notbe subjected to the closed. he will noty be subjected to the aiiiioyance of getting hold of an undeforined end and attempting to put it into a slotted post such as $5 which will not receive it.

'In addition to this, it' is evident that should one owning a Wire tying machine purchase wires 21, 210, see Fig 9, of difannoyanee 0f nding that the flattened cross sections 80 of his different sized wires are iinsuited to the slot 86 in his ost 85 with which his machine is provide for owing I to the throw of 1the deforming members 45 being uniform no matter what may be the size. of the wire being defoi'iiied. ythe cross sections S0 will always he uniform. The

been caught on curved arms 59 the dog 73 will lift, thus releasing said arms 69 and p permitting the bundle of straightened and deformed wires to fall by gravity into the curved arms or rack 64, whence they may lie taken and packaged ready for shipment.

lt will now he seen that wires such as 21 .of various sizes may be readily drawn through the straightening rollers 22 and-23 from a coil not shown, so that all tendency to kinlcor twist is taken out of said wires, that the wires are rapidly 'forced with certainty for a predetermined distance into the flutes of thendrum 5() so that they are automatically measured as to length whereupon they are rapidly deformedv and severed into predetermined lengths. clear that should it be desired to have the lengths of the severed wires changed, it is It will further be only necessary to change the'speed of the shafts 20 and 27 which is rfadily effected hy manipulating the change speed gears 6 and 7 in the manner well known.

' )f course. instead ofiiiahing the deformed portion 80 fiat in cross section it may be made round in cross section or it may have any other desired cross sectional shape.

It is obvious that those skilled in tlie art may vary the details of construction as well as the arrangement of parts without departing from the spirit of our invention, and therefore, we do not wish t0 be limited to the above disclosure except as may be required hy the claims.
