lWIRE SHAPING AND FORMING- MACHINE.

To all whom it may concern:

Be it known that I, HERBERT J. BEAGDON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Wire Shaping and Forming Machine, of which the following is a specification.

The 'wire shaping and forming machine that is the subject of my invention has for its object the forming and shaping of pieces of wire into various objects adapted to be made of wire.

This specification particularly describes the machine as adapted to shape and form small wire tag holders, but by varying the shapes of the die and plungers, hereinafter referred to, and by varying the adjustments of the different parts of the machine, wire rings or wire cli s or any other object adapted to be formed y bending wire may be made, as will be readily understood upon consideration of the mechanism hereinafter described.

In the accom anying drawings, Figure 1 is a plan view o the machine as 'seen from above Fig. 2 is a section on the line 2 2 of Fig. l showing a side view of the forming die and the rotating plungers; Fig. 3 is a section on the line 3 3 of Fig. 1., showing a side view of the a aratus for cutting the wire into the requirelfengths; Fig. 4 is a plan view of the forming die 3 Fig. 5 is a front view of the forming die, Fig. 6 is a section on the line 6 6 of Fig. 4 Fig. 7 is a perspective view of the cam which is attached to the die for throwing off the completed article 5 Fig. 8 is a section on the linel 8 8 of Fig. 1, showing the cutter bearing mechanism and the means of attaching said mechanism to the driving shaft; Fig. 9 is a section taken on the line 9 9 of Fig. 8; Fig. 1() is a side view, partly in section, of one of the forming plungers, showing the mechanism for throwing the completed article off the plunger; Fig. 11 is a view of the forming plungers taken from the front, showing the same mechanism for throwing off the completed article; Fig. 12 is a detailed view of the reciprocating pin which passes through the outer end of each plunger and throws Aoff the completed object', and Fig. 13 is a view in perspective of a tag fastener as formed by this machine. i

the structure and operation of the machine before entering into a detailed explanation referring to the figures on the drawings.

The entire apparatus will take up very little space. The frame of the machine is made of suitable metal and is supported on legs,

' made of suitable metal or other material, which bring the mechanism up to a conven- Vient height from the floor for the purposes of operation.

In the front of and at one side of the machine may be placed a drum or spool on which the wire which is to be out and formed is wound. This drum or spool is not shown in the drawing but would be placed at the lower left-hand corner of the machine shown in Fig. l of the drawings. The end of the wire is then assed between a pair of feed rollers, and t v1e machine is ready for operation.

All the power for operating the machine is applied to a pulley which is attached to a driving shaft passing through the center of the frame of the machine. The frame of the machine and the various parts may be of different sizes for the purpose of making articles of different sizes, but in the machine described in this specification, which is, as stated, adapted for the formation of wire tag holders, the frame of the machine is only about twenty-three inches by twenty-four inches.

After the end of the wire has been inserted between the feed rollers and the power turned on, the feed rollers feed the wire into the machine in a direction parallel with the driving shaft. After the wire has been fed in tothe upper inner edge of the forming die, one of the four cutters which revolve around the driving shaft immediately outside of the upper outer edge of the forming die, cuts the wire against a stationary cutting edge, leaving within the forming die at its u per edge a section of wire just equal in lengt i to the entire length of the completed article. Just as this section of wire is cut by the cutter, one of the four plungers, which also rotate around the power shaft, descends upon the section of wire which has been out off and forces it downward through the forming die, which is stationary, and occupies the s ace of about a quarter of a circle which has t e center of the power shaft as its center. This forming die at its upper edge is straight but the outer lleased and is t rown into its former position edges of it are gradually formed upwards and then inwards towards each other so that at its under end it is so shaped that as the wire j is forced through it by the lunger, the outer ends of the wire are bent rst upwards and then inwards towards each other.

Near the lower end of the forming die a cam is attached to it which extends perpendicularly above it and has its upper end bent at right angles in over the forming die. On the plunger is pivoted an arm which projects out above it and carries pivoted to it another arm at right angles to the first one extending toward the outer edge of the plunger. This arm in turn carries a pin which extends through an opening in the end of the plunger and carries a cam on its end. As the plunger presses the wire through the die the aforesaid cam attached to the die catches the arm pivoted to the plunger and depresses it, thereby depressing the pin whici projects through the edge of the plunger and throws oli the completed article into a sack which may be placed to receive it. As soon as the plunger passes the said cam attached to the die, the arm ivoted to said plunger is reby a spring which passes around the pin which extends through the end of the plunger.

While the one section of wire has been so shaped in the die by one of the plungers, the uncut wire has been fed in until another sece tion is in place at the upper edge of the die, when it in turn is cut oli by another of the cutters and is carried through theA die by another plunger. On the machine shown in the drawings and described in this s ecification there are four cutters and four ungers.

Having now described the genera method of operation of the machine, l will enter upon a more particular description of the various details, referring to the drawings and the numerals thereon indicating the specific parts of the machine.

1 is the upper of the two guide rollers, (the under one of which is grooved for better feeding the wire) through which the wire is fed into the machine from the spool or drum (not shown).

2 and 3 are the gears by which the roller 1 and itscounterpart are driven. The gear 3 is attached to and rotates with the main driving shaft 4, which is driven by a belt applied to the pulley 5. j

6 is a pi e through which the wire is fed from the ro lers 1. This pipe is bolted to the frame of the machine as indicated at 7.

8 is the stationary cutter-bar, which is bolted by the bolt 9 to a slot 10 in the frame of the machine, thus being adjustable on said frame.

11 are the four rotating cutters which are sunk into four openings prepared for them on the wheel 12, to which is screwed the plate 13 by the screws 14. This wheel 12 is held rigidly attached to the driving shaft 4 by the bolt 15 and the feather 16. The rotating cutters 1.1 are held in place by the bolts 18, and when the bolts 18 are loosened, the rotat` ing cutters 11 may be removed from thel openings in which they are placed, and may then be adjusted vertically by means of the bolts 17. The rotating cutters are also capable of adjustment around the driving shaft by means of the bolts 19 which fit in the slots 20 this enables the rotating cutters to be adjusted forwards or backwards so as to adapt the cutting of the wire to the operation of the forming plungers, hereafter described,

The stationary cutter-bar 8 has bolted.on

it on its upper side a guide bar 21, for guiding the wire into the guides 29 at the upper end of the forming die. As the wire feeds out of the tube 6 and through the cutter it passes underthe guide 29, which is secured at the head of the forming die 28. This guide 29 is bolted to the frame of the machine by the bolts 27 and the bolt 25, the latter being adjust'able in the slot 26. The forming die 28 is bolted to the machine by the bolts 22, which are adjustable in the slot 23.

The forming die 28, when attached to the frame of the machine by the bolts 22,' eX- tends directly under the wheel which carries the forming plungers; and this forming die occupies about the space of a quarter of a circle, said circle having for its center the center of the driving shaft of the machine. At its head the forming die presents a straight surface, but both outer edges of it, beginning shortly below its head, are gradually bent upwards and inwards as shown at the points indicated by the numerals 30. This bending may be varied as it is desired to vary the shape into which the wire is to be bent, without departing from the spirit of my invention. In the accompanying drawings the die is formed so as to properly bend the wire into the shape of the tag fastener 31.

The wheel 32 which carries the forming plungers is fastened to the driving shaft in the same manner as is the wheel 12, which carries the rotating cutters 11. The bolt 33 corresponds to the bolt 15. The bolts 34 correspond to the bolts 19 and permit of the rotary adjustment of the forming plungers in the same manner as the rotary adjustment of the rotating cutters, and the bolts 35 correspond to the bolts 18 and permit of the vertical adjustment of the forming plungers in the same manner as the vertical adjustment of the rotating cutters.

The forming plungers, on the surface which comes in contact with the wire, carry the rigid projections 36 and 37, which may also be made of such size and of such shape as may be necessary to fit in the recesses formed by the bent upper edges of the forming die. ln the drawings the projection 36 is larger than the projection 37 because the recess formed As the driving shaft revolves carrying the wheel which in turn carries the forming plungers 33a, the plunger comes 1n contact with the cut section of wire at the head of the forming die and carries it down through the forming die, the projection 36 passing along and through the recess 38 in the forming die and the projection 37 passing along and through the recess 39 in the forming die, thus the ends of the section of wire are bent up and around the projections 36 and 37 toward each other and the completed article, as shown in Fig. 13, is formed. As soon as the completed article is formed it is thrown off the forming plunger by the mechanism hereinafter described, and in the meanwhile the next forming plunger has made another article, and so on.

On each of the forming plungers is pivoted an arm 40 which bears a roller 4l. To this arm is also pivoted another arm 42, extending at right angles from the first arm and toward the head of the forming plunger. rlhe arm 42 comes in contact with the reciprocating pin 43 which extends through the head of the forming lunger, and carries on its end the lug 44, w iich fits in a recess on the head of the forming plunger between the projections 36 and 37. Around the reciprocating pin 43 is fastened the spiral spring 45. To the forming die, at the point where the bending of the wire is completed, is bolted, by the bolt 46, the cam 47, which bears the lug 4S. A's the forming plunger descends, the roller 41 strikes the lug 48, whereby the arm 42 is forced downward and the reciprocating pin 43 is forced downward throwing the lug 44 out between the projections 36 and 37 and ejecting the completed article from the head of the forming plunger. As the plunger passes the cam 47 and the roller 41 is released from contact with the lugI 48, the spiral spring throws the ejecting mechanism into its original position, and the arm 4() is prevented. from springing too far in the opposite direction by the stop 51. T he wheel 49 is a fiy-wheel at the other end of the driving shaft.

The lubrication of the die and forming plungers is most effectively done by allowing oil to drip onto the wire, either through holes, not shown in the drawings, cut through the upper side of the tube 6, or at the end of said tube. Another possible method of lubrication is indicated by the recesses 5() shown in the drawings as formed at the head of the i forming die, into which oil may be allowed to drip.
