WIRE-DRAWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 553,353, dated January 21, 1896.

Application filed December 14,1893. Serial No. 493,636. (No model.)

To all whom it may concern:

Be it known that I, CHARLES H. MORGAN, a citizen of the United States, residing at orcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in \Vire Drawing Machines, of which the following is a specification, accompanied by drawings representin g a reel embodying my invention, in which- Figure 1 represents a side elevation of my improved wire-drawing machine. Fig. 2 is a central sectional view of the wire-drawing drum or block and the detachable reel connected therewith. Fig. 3 is a plan view of the r 5 machine, and Fig. 4 is a side view of the machine, representing the coils of wire in the act of falling from the upper portion of the drawing-block upon the arms of the reel, said Fig. 4 also illustrating the adaptation of my improved reel as a delivering-reel.

Similar letters refer to similar parts in the different figures.

The object of my present invention is to provide means adapted to be employed in connection with wire drawing mechanism by which the coils of wire, as they are successively wound upon the drum or block in the operation of wire-drawing, shall be automatically delivered therefrom an d received upon the reel, to provide means for increasing the capacity of the reel in order to enable greater lengths of wire to be continuously drawn, and, further, to adapt the reel to be conveniently and readily connected with and detached from the drum or block of a wire-drawin g bench or machine in orderto allow the reel to be used both as a receiving and delivering reel and obviatethe necessity of handling the wire, which by the use of my improved reel can be drawn continuously in coils of greater Weight.

Referring to the drawings, A denotes the framework of a Wire-drawing machine supportinga fixedstud or spindle A, upon which is j ournaled a rotating drum or block B having its face B preferably slightly tapering with the lower end of the drum the smallest, and provided at its upper end with a flange B arranged to rotate in the plane of a wiredrawing die C so the drawn wire as the drum B rotates will be conducted by the flange 13 upon the cylindrical face Bof the drum.

The lower end of the drunrB is provided with an annular lip B fitting a shoulder D upon an annular plate D, by which the plate 5 5 D when brought into engagement with the lip 13 is held concentrically with the drum B. The annular plate D forms the upper head of the reel, the lower head of the reel consisting of a circular plate D which is provided with a small central recess (indicated by the broken lines in Figs. 1 and 2) adapted to fit the upper end of a spindle E, which serves as a step to support the reel. The plates D and D forming the fixed heads are connected by rods D forming the body of the reel.

The diameter of the reel, formed by the rods D is preferably slightly contracted in diameter at its lower end and the annular plate D is made of the same diameter as the diameter of the smaller end of the drum B and the outer sides of the rods 1) are flush with the edge of the annular plate or head D so as to allow the coils of wire, as they are placed upon or removed from the reel, to pass freely over the plate I). 5

The lower head D of the reel supports a fixed post F attached to the head D and extending upwardly and centrally between the rods D Adapted to slide upon the post F is a plate F provided with a hub F in order to forma suitable bearing upon the post, the lower end of the hub F resting upon the upper end of the spiral. spring F held upon the post F and between the sliding plate F and head D with the tension of the spring applied to raise and support the sliding plate F. Arms D are pivoted upon the upper surface of the lower head D and similar arms 0 F are pivoted upon the upper surface of the sliding plate F, these arms being arranged to extend radially from the head D and plate F and project beyond the rods D to receive the coils of wire as they are delivered from the rotating drum B, but capable of being turned upon their pivots wholly within the circumference of the head D and plate F when required.

The spindle E is capable of a vertical slid- 10o ing motion in the framework of the machine and is provided with connected means by which it and the reel supported thereon may be raised to bring the annular plate or head D into engagement with the end of the rotating drum, and lowered to release the reel and allow it to be removed from the drum.

The mechanism represented in the accompanying drawings to accomplish the raising and lowering of the step-spindle E consists of apivoted foot-treadle G, which is depressed by the operator to raise the reel into the position shown in Figs. 1 and 4, and is locked.

by a pivoted latch G.

The annular plate or head D is provided with a series of concentric holes I-I, arranged to be engaged by a pin I-I projecting from the end of the rotating drum B, causing the rotation of the drum to be imparted to the reel. attached bevel-gear I engaging a pinion I upon the horizontal driving-shaft 1 which is driven by means of a belt-pulley 13.

The operation of 'my improved reel is as follows: The wire to be drawn is taken from a reel J, Fig. 1, through the die 0 and wound upon the rotating drum B in the usual manner, the wire being laid upon the drum B in a series of coils, which are crowded down as each succeeding coil is wound upon the drum immediately beneath the projecting flange B As the wire is wound upon the drum B, the several coils will be thus pushed downward upon the surface of the drum until the friction between the face of the drum and the advancing coils of wire is sufficiently reduced, when several coils will fall by their own weight over the surface of the drum and be caught by the projecting ends of the arms F. In practice the wire has been found to fall intermittently, several coils falling simultaneously, and in Fig. 4 I have represented at K four coils of wire as in the act of falling from the upper to the lower end of the rotating drum B. The coils of drawn wire are in the manner described deposited upon the arms F and as the accumulating wire held upon the arms F- increases in weight, the spiral spring F is gradually compressed, allowing the plate F with its load of wire to descend. The arms F are then turned upon their pivots, carrying them within the circumference of the plate F, allowing the wire held upon the arms F to fall upon the arms D when the plate F, being relieved of its load, again rises into its elevated position, the arms F are again extended, and the operation of re loading resumed, each successive load being transferred to the arms D until the reel is filled. When the reel is filled, the step-spindle E is released and the reel lowered and disengaged from the end of the rotatingdrum,

so it may be removed and replaced by an empty reel. The filled reel is supported in The drum B is rotated by means of its wire by providing theannular plate D with a cone N and a ring N lying loosely upon the cone. The wire is withdrawn from the upper end of the reel by being carried between the cone N and ring N and through a guidering N supported over the reel'in the usual manner. I

It has been common heretofore to employ a cylindrical drum or block upon which the wire is wound in the operation of wire-drawing, said block having tapering sides, and as the individual coils of wire were wound upon the blockthey were lifted or crowded upward along the tapering sides of the block and it has been common to increase the capacity of the block for holding wire by means of rods or arms projecting upwardly, so as to-increase the length available for holding the wound wire; but this arrangement does not permit wire to be drawn continuously in great lengths for the reason that the weight of the wire accumulated upon the block soon becomestoo great to allow the wire to be raised by the operation of winding the succeeding coils upon the block. By reversing the drum or block and applying a reel to the end of the block having its axis coincident with the axis of the the block: the wire is held by frictional contact upon the surface of the block until it is crowded downward upon the face of the block and the friction becomes insufficient to sustain the weight of the wire. It will be obvious that a short reel might be employed and the wire dropped from the block directly upon the arms D but by the employment of an intermediate sliding plate F, with its projecting arms, I am enabled to increase the length and capacity of the reel, as the wire in falling by gravity will need to fall only the length of the drum or block, and consequently decrease the length of the wire wound spirally around the reel and connecting the coils at the upper end of the block with the coils resting upon the lower arms D I deem it to be broadly new to provide a wire-drawin g drum or block to be used in an inverted position, so the coils of wire will be held against gravity when first wound upon the block by the frictional "resistance between the coils of wire and the surface of the block, and subsequently released by the decrease in the frictional resistance, and I also deem it to be broadly new to provide a receiving wire-reel held at the end of a wiredrawing block and coincident therewith, so the wire in falling will pass from the block upon the reel, and so far as these features of my invention are concerned I do not confine myself to any specific form of construction of the wire-reel or of the mechanism by which it is raised and lowered in order to bring it into or out of engagement with the wire-drawing block; neither do I desire to confine myself to the employment of a reel applied to the end of a wire-drawing block, as it is obvious that with an inverted block as the component part of a wire-drawing machine the wire can be delivered from the end of the block by the intermittent falling of each successive group of coils over the surface of the block whatever the form or construction of the receiving-reel may be and whatever its special method of connection with the block. In fact, the operation of the block in holding a sufiicient number of coils to produce the requisite amount of tension or pull upon the wire to draw it through the die or draw plate, and when that has been secured to cause the wire to be released so as to be carried off the block by the force of gravity, is entirely independent of the receiving device, and would be secured if the wire fell off the lower end of the block upon the floor of the mill or upon a shelf or platform arranged to secure it.
