2 Claims.

The instant invention relates to wire-cuttin machines and more particularly to such a machine which automatically cuts wire from a reel into predetermined uniform lengths.

One of the primary objects of the invention is the construction of an apparatus of the character indicated which will automatically unreel, measure and out a wire rope into pieces of predetermined uniform length.

Still a further aim is the formation of a machine of the type above specified in which the cutting of the wire is electrically controlled and in which the wire being cut serves as the conductor of electric current for controlling the cutting operation.

Yet another purpose is the manufacture of an apparatus of the character set out above which will be eflicient in use, formed of comparatively few parts and capable of assembly and operation at relatively low cost.

The above and other aims and objects will be apparent from the detailed description hereinafter appearing when taken in conjunction with the appended drawings forming a part hereof to which attention is now directed and in which Figure 1 is a plan view of the novel wire cutting machine;

Figure 2 is a side elevational view, partly in section, of the machine of Figure 1;

Figure 3 is a sectional View taken on line 3-3 of Figure l;

Figured is a sectional view taken on line i-4 of Figure 1;

Figure 5 is a sectional view taken on line 5-5 of Figure 2; and

Figure 6 is a detailed sectionalview of a longitudinally apertured guide member.

Referring now to the drawings by reference characters and in which like characters designate like parts in the several views, the letter B indicates the base of the machine which carries a motor M, a solenoid-operated cutter S and a cutting control and disposal unit U The motor M has a drive shaft I provided with a worm H for rotating driven shaft l2 which, in turn, has a wire feeding wheel l3 and sprocket l4 keyed thereto. Shaft H] is supported in spaced bearings l5, Ia and the feeding wheel l3 and sprocket M are in spaced relation on said shaft -see Figs. 1 and 3. The periphery of feed wheel I3 is grooved and is equipped with a fibre V-belt [6, while cooperating with said wheel is an idler wheel l1 rotatable on fixed shaft l8 mounted on a supporting standard I9 attached to base B.

Idler i1 is preferably formed of rubber or other insulating material.

Reference character W designates the wire which is unreeled from a reel or the like (not shown) to the left in'Figs. 1 and 2 by means of feed wheel l3 and its cooperating'idler H, the wire being gripped by fibre V-belt I6 and the rubber material of said idler. Means are provided I for guiding the wire W comprising aligned tubes 19 and 20 on each side of solenoid-operated cutter'S. Tube l9 has an apertured guide member i9d-see Fig. 6. Tube 20 is preferably supported intermediate its length by an upright supporting member 2| positioned on base B, the latter carrying the unit U comprising wire disposal fibre roller 22 on the end opposite to that on which connects said sprockets. An idler wheel 21, pref-' erably of brass or the like, cooperates with fibre wheel or roller 22 in a manner to be described more in detail hereinafter. Spaced brackets 24' are adjustable lengthwise of base B, either to the right or to the left as viewed in Figs. 1 and 2, for a purpose which will shortly be apparent.

Turning now to Fig. 5, there is shown a solenoid-operated cuttingmember comprising a solenoid 28, having a movable core 23a for actuating a cutting member 29 carried by a movable plate 30 guided by posts 3| against tension of coil springs 32 surrounding said posts. The reference numeral 33 designates a die holder for cooperation with said cutting member. Brass idler 21 is rotatably mounted on a stub shaft 21a carried by a bracket 2117. An angle iron 210 is rigidly held on stub shaft 21a and supports a spring pressed electrical contact pin 21d in contact with idler 21.

The operation of the apparatus just described is as follows:

Current is fed to the wire W prior to reaching feed wheel l3 by a contact member 35 or the like. Insulated wheel l3 and its rubber idler I! are actuated by the motor M and feed wire W through solenoid-operated cutter S to fibre disposal roller 22 and brass idler 21. The latter is electrically connected to the solenoid 28 of cutter unit S by a current conductor 36. When the forward end of the wire reaches idler 21 the circuit is completed and the solenoid-operated cutting member 29 severs the wire thus breaking the circuit. The severed wire is disposed of by the roller 22 which is tfi fi y Sprocket chain Iii Will be I when said memberis contacted by the currentticulariy noted that brass idler V2: a dual carrying wire,
