WIRE-CUTTING MECHANISM.-

Specification of Letters Patent.

Patented Nov. 28, 1905.

Application filed December 80,1904. Serial No. 238,985. I

State ofIllinois, have invented certain new and useful Improvements in Wire-Cutting Mechanisms, of which the following is a specification.

The present inventionrelates to wire-coiling machines, and has for its object to pro- Vide a simple and eflicient structural formation and combination of parts whereby the wire as coiled .is automatically cut oil in predetermined lengths in a certain and accurate manner and without interference with the normal operation of the coil-formingmechanism, all as will hereinafter-more fully appear, and be more particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view, partly diagrammatic, of the present mechanism. Fig. 2 is a detail perspective view of the spreader-plate, by which the desired spread between the convolutions of the wire coil is attained.

Similar numerals of reference indicate like parts in both views. I

Referring to the drawings, 1 is the central arbor, around which the wire is formed into a coil 2 by the pair of revolving forming heads or disks 3 and 4, as usual in the present/class of machines. The said heads are preferably arranged to revolve upon stationary spindles 5 and 6, having confining-nuts 7 and 8 on their outer ends to hold said heads in place in the manner indicated in Fig. 1. i

9 is a spreader-plate secured to one of the spindles aforesaid or to any other suitable and stationary part of the machine in a non-revoluble yet circularly-adjustable manner for the purpose hereinafter stated. In the construction shown said spreader-plate extends into closely-adjacent relation to the arbor 1 aforesaid and has a circular and tapering margin 10, adapted to fit between the individual convolutions of the wire coil 2 as it leaves the forming-heads aforesaid to effect a spreading apart of said convolutions, and the amount of such spread is governed by a circular adjustment of said spreader-plate to bring a thicker or thinner portion of the tapering margin 10 thelreof into active relation to the said wire 001 t 11 is the stationary cutter-blade, and 12 the movable cutter-blade, of a cutting mechanism arranged in the path of the wire coil 2 as it passes away from the coiling mechanism'before described. 13 is a spring encircling the shank of the movable cutter-blade 12 and adapted to draw the same away from the stationarycutter-blade l1 aforesaid. I

14 is an armature attached to the rear end of the carrying-shank of the

movable cutterblade

12, and 15 is an electromagnet adapted when energized to attract said armature and impart a positive forward or cutting movement to said movable cutter-blade to sever the coil of wire at the point betweenthe cutterblades. w

16 isa circuit closer operated by an electromagnet 17 and controlling a local circuit which embraces the aforesaid electromagnet 15 and a battery 18 or other sourceof electromotive force.

1 9 is a secondary circuit-closer controllinga local circuit which embraces the operating electromagnet. 17 of the circuit-closer 16 and the battery 18'or other source of electromotive force.

' It is within the scope of the present invention to omit the circuit-closer'16 and embrace the cutter-operating electromagnet 15 in circuit with the circuit-c1oser19 in order to operate said electromagnet 15 in a direct manner in many uses of the present invention where a heavy electromo'tive force is not required to operate the movable blade of the cutter mechanism.

In the present improvement the circuitcloser 19 is arranged in the path of the wire coil 2 as it moves through the cutting mechanism and comprises a stationary contact member 20 and a movable contact member 21 insulated from each other with the. movable member in front of the stationary member,

and so that as the wire coil 2 in its longitudinal travel contacts with the-movable member 21 it will move the same into contact with the.

stationary member 20 to close the circuit upon the operating-electromagnet .17- of the circuit closer 16, to in turn close the circuit on the operatingelectromagnet 15 of the cutting mechanism to force the movable blade of such cutting mechanism forward and sever the end of the wire coil 2, which extends beyond said cutter-blade;

22 is a carrier for the contact members 20 and 21 aforesaid, which in the preferred form of the present invention .is secured in an adjustable manner upon a longitudinal guide rail or way 23, so that the distance-between the circuit-closer 19 and the cutting mechanism can be adjusted as required in cutting the wire coil 2 into pieces of the required length. Having thus fullydescribed my said invention, what I claim as new, and desire to secure 2. The combination of a mechanism adapted to 'feed a wire coil or the like in a longitudinal direction, a fixed cutter and a reciprocating cutter arranged in the path of said wire coil or the like, an-electromagnet adapted to impart rectilinear movement to said reciprocating cutter, a circuit-closer arranged in a longitudinally-adjustable manner in the path of the wire coil or the like passing beyond the cutting mechanism, and a source of electromotive force embracing said electromagnetic mechanism and controlled by said circuitcloser, substantially as set forth.

3. The combination of a coil-forming mechanism, a fixed cutter and a reciprocating cut- I ter arranged in the path of said wire coil or the like, an electromagnet adapted to impart rectilinear movement to said reciprocating cutter, a circuit-closer arranged in the path of the wire coil passing beyond the cutting -mechanism, and a. source of electromotive force embracing said electromagnetic mech anism and controlled by said circuit-closer, substantially as set forth.

45., The combination of a coil-forming mechanism, a fixed cutter and a reciprocating cutter arranged in the path of said wire coil or the like, an electromagnet adapted to impart soavaa rectilinear movement to said reciprocating cutter, a circuit-closer arranged in a' longitudinally-adjustable mannerin the path of the wire coil passing beyond the cutting mechanism, and a source of electromotive force. embracing said electromagnetic mechanism and controlled by said circuit-closer, substantially as set forth.

5. The combinatlon of a mechanism adapted to feed a wire coil or the like in a longitudinal direction, a cutting mechanism arranged in the path of said wi're coil or the like, an electromagnetic mechanismfor operating said cutting mechanism, an electromagnetic circuitcloser, a local source of electromotive force embracing the electromagnetic operating mechanism of the cutting mechanism and controlled by said electromagneticcircuit-closer, a secondary circuit-clo er arranged in the path of the wire coil passing beyond the cuttingmechanism, and a local source of electromotive force 'embracingthe operating electromagnet of the electromagnetic circuit-closer aforesaid and controlled by said secondary circuit-closer, substantially as set forth.

6. The combination of a mechanism adapted to feed a wire coil or the like in a longitudinal direction, a cutting. mechanism arranged in the path of said wire coil or the like, anelectromagnetic mechanism for operating said cutting mechanism, an'electromagnetic circuitcloser, a local "source of electromotive force embracing the electromagnetic operating mechanism of the cutting mechanism and controlled by said electromagnetic circuit-closer, a sacondary circuitcloser' arranged in a longitudinally-adjustablemanner in the path of the wire coil passing beyond the cutting mechanism, and a local source ofelectromotive force embracing the operating-electromagnet -of the electromagnetic circuit-closer aforesaid and controlled by said secondary circuitcloser, substantially as set forth.
