MACHINE FOR ROLLING RODS OR WIRE.

SPECIFICATION forming part of Letters Patent No. 599,338, dated February 22, 1898.

Application filed February 3, 1897. Serial No. 621,760. (No model.)

To ctZZ whom it may concern.-

Be it known that I, ABEL KENwoRrHY, a citizen of the United States,residing at VVaterbury, in the county of New Haven and State of Connecticut,have invented certain new and useful Improvements in Machines for Rolling Rods or Wire, (Case 0;) and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for making wire from rods or reducing the diameter and increasing the length of rods or wire, and has particular reference to that type of machines which operate upon the metal by rolling as distinguished from drawing.

Among other objections to the method of drawing are the slowness, as compared with rolling, and the fact that the rods or wire must be pickled and washed between successive operations after annealing, for the reason that the black coating on the wire as it comes from the annealing-furnace interferes with the action of the die and with the production of perfect wire.

In another concurrently-filed application, Serial No. 621,758, I have shown a machine which gives a double reducing operation during a single pass of the wire, both sets of reducing-rolls being positively driven, but at different speeds, and in another concurrentlyfiled application, Serial No. 621,759, I have shown a machine which also gives a double reducing operation during a single pass of the wire, the first reducing-rolls being idlerollst'. a, not driven-while the second reducing-rolls are positively driven and serve to feed the wire through both sets; but in the use of this last-mentioned machine it is nec essary that the end of the wire or rod shall be first primarily reduced or pointed for a short distance in order that the said end may be readily pushed between the nondriven rolls by the attendant until the end is grasped by the driven reducing-rol1s, so that the wire may then be automatically passed through the machine and given two reductions at a single pass.

In the present invention I have embodied somewhat of the principles of both of the other machines referred to in that while the first set of rolls is positively driven for a short time to pass the end of the wire to the second set and give the primary reduction, yet after the second set begins to act and give the second reduction the rolls of the first set cease to be driven and become idler reducing-rolls. In this machine, therefore, I dispense with the necessity of first pointing the wire and also avoid the difficulties sometimes experienced in securing the nicety of adjustment of speed between the two sets of rolls positively driven. The present ma chine, moreover, is not only adapted to give two reductions during each pass of brass wire, but is also adapted to give four reductions during a single pass of copper wire. To explain the desirability of this feature, I will state here that in order to produce the best results in brass wire it should be annealed after it has been given two reductions, while copper wire does not require this treatment. In this machine I have also provided an improved coiling-drum especially adapted for this type of machine and certain other improvements, all of which I will proceed to de scribe, and then specify more particularly in the claims.

In the accompanying drawings, Figure 1 represents a plan view of the complete machine. Fig. 2 represents a side elevation of the same. Fig. 3 represents a detail elevation of the first pair of reducing-rolls and the means whereby they are adapted to be driven or to become idlers. Fig. 4 represents a section on line X X of Fig. 3. Fig. 5 represents a detail elevation of the coiling drum, portions thereof being broken away to show the interior, part of the outer end of the drum being in section on the line Y Y of Fig. 6. Fig. 6 represents an end View from the right of Fig. 5. Fig. 7 represents a detail of the mechanism for automatically starting the drum. The relative positions of the parts shown in this figure can readily be seen by comparing it with Fig. 1 after placing one of the sheets with the signatures uppermost.

Fig. 8 represents a detail, partly in section, from apoint below Fig. 7. Fig. 9 represents a detail View from the position shown by the arrow, Fig. 8, said Fig. 9 being an enlargement of some of the parts shown in Fig. 6.

Similar reference characters indicate similar parts in all the views.

The bed of the machine is indicated in Figs. 1 and 2 at A, suitable standards or legs therefor being indicated at a. Near each end of the bed is a rolling mechanism, the one at the left being indicated in its entirety by B and the one at the right being indicated in its entirety by B. These two mechanisms are substantially identical with each other, except that the second one (at the right) is provided in practice with rolls adapted to give greater reduction to the wire. Since the rolls of the said second mechanism when used must have greater surface speed than the first, I have indicated one way of accomplishing this by providing larger reducing-rolls and by having its main driving-pulley b smaller than the main driving-pulley b of the first mechanism, these pulleys being driven by one belt, as at C. The said belt also passes over an intermediate pulley d.

The two reducing-machines B and B being substantially alike, reference to the mechanism of one will sufiice for both, similar parts in the second machine having a prime-mark after the reference-numerals.

The first reducing-rolls 1 are mounted in boxes adj ustably supported in a frame or casting 2, the gearing for adjusting the boxes being indicated at 3. The two rolls 1 are geared together, as at 4, and the lower end of one of the shafts is made angular. (See Figs. 3 and 4.) On this angular portion is fitted a sleeve 5, having a ratchet-toothed face, said sleeve being adapted to slide on the shaft, but not to rotate thereon. A shaft 6 abuts against the end of the sleeve-carrying shaft and is provided with a ratchet-toothed disk 7 to engage the teeth of sleeve 5 and rotate it and the rolls. The shaft 6 is driven continuously by means of the shaft 8 under the bed through the medium of bevel-gears 9 on the shafts 6 and 8, the direction of rotation being to feed the wire through the rolls and reduce it. The second red ucing-rolls 10 are mounted in boxes adjustably supported in a frame or casting 11, the gearing for adjusting the boxes being indicated at 12. The two rolls are geared to rotate together, the shaft of one of them being indicated at 13, and driven by the pulley b or b. The speed of rotation of the second reducing-rolls is sufficiently greater than the initial driven speed of the first reducing-rolls to insure that after the wire has been taken by the second rolls it will be caused to travel between the first rolls at a speed faster than that imparted by the shaft 6, the ratchet connection at 5 and 7 permitting this, owing to the sleeve 5 being free to rise and move faster than the disk.7. Therefore while the rolls of the first set are positively driven at first to' carry the end of the wire through to the second set and give the first reduction after the wire is taken by the second set and further reduced and moved faster the first set become idlerolls, but still reducing-rolls. After the wire leaves the second reducing-rolls it passes to the coiler, if the latter is to be used, as for brass wire. This coiler consists of a shield 14:, secured to a standard 15, adapted to slide in ways transverse to the bed A, said shield being cut, as at 16, the portion at the left of which is bent outward. Back of the outwardly-bent portion are two rolls 17, between which the wire is passed, said wire being then deflected and given a downward curve by means of a roll 18, the wire then coiling up and around a stud 19, projecting from the outer face of the outwardly-bent portion of the shield. This coiling device is capable of taking as much brass Wire as is commonly handled in single coils which must be placed in the annealing-furnace; but when copper wire is to be reducedit is passed through the rolling-machine B as well and is therefore givenfourreductions. Atthistimetheshield 14 is detached from the standard 15, and the latter is moved out of the Way by means of the sliding support. (See dotted lines in Fig. l.) The treatment of wire in the second red ucingmachine B is the same as in the first machine B, the shaft 6 being driven from the shaft 8, and the latter being driven from a shaft 20, having the pulley d, the reducing-rolls 10 of this mechanism being driven by pulley b.

As shown in Fig. 2, the gearing at the right of shaft Sis such as to drive the vertical shaft I 6 considerably faster than the shaft 6.

It will now be understood that as a whole this machine comprises four sets of reducingrolls, the second and fourth of which are always driven, while the first and third are idler reducing-rolls during all but the initial operation of passing the end of the wire to the driven rolls, and all four sets operate to successively reduce the wire four times during a single pass. This insures much greater production in a given time than has been accomplished by any machine or set of machines that I am aware of.

Since copper wire is treated in much greater quantities as to the length and weight of single pieces, I have devised a coiling-drum which is adapted to receive and retain a much greater weight and length than the coiling device above described for brass wire.

To one end of the bed A are secured two brackets 21 21, one of which has a standard 22. A shaft 23 is mounted in the brackets and projects at one end to support the drum, presently described. On the shaft is mounted a pulley 24, driven by a belt. (Not shown.) This pulley is adapted to be connected at times to the shaft to drive it by means of a suitable clutch, one member of which is indicated at 25. Since there is nothing novel in the particular clutch used, I have not attempted to show it in detail, it being sufficient to state that the clutch is operated by means of a lever 26, pivoted at 27 and connected to the clutch member by collar 28, a spring 29 being connected to the lever to cause the latter when released by a catch, presently described, to operate the clutch so as to connect the pulley with the shaft.

On the outer end of the shaft is secured the drum 30, having a flange 31 and a slot 32 from the flange to the outer edge. This drum is supported on the shaft by the arms at the outer end in order that the inner end of the drum may receive and rotate around the latch and bending-stud, presently described, and which project from the standard 22 within the flanged end of the drum.

The latch 34 (see Figs. 7, 8, and 9) is pivoted at 35 to the standard 22 and has its hooked end adapted to engage the outer side of the upper end of lever 26 to hold it in the position shown in Fig. 5 when the drum is to be stationary. The other end of the latch is flattened to form a plate 36, which lies in the path of movement of the end of the Wire, which is directed by the last set of reducing-rolls through an opening 37 in the drum at the inner end of and communicating with the slot 32. When the end of the wire abuts against plate 36, it actuates the latch to release the lever 26, and then the spring 29 causes the lever to operate the clutch to start the drum.

The bending-stud 38 is mounted to rotate freely in a bearing in the standard 22 and projects inside the drum between plate 36 and the hole 37. (See Fig. 9.) This stud is provided with a hole 39, one end of each side wall of the hole 39 being rounded, as at 40. The wire entering hole 37 passes into and through the hole 39 until it abuts against the plate 36. The drum instantly begins to rotate in the direction of the arrow, Fig. 9, and the lower side of the slot 32 in the drum carries the Wire upward, and the stud 38 rotates half-way, thus causing the end of the wire to be bent so as to hook the end of the wire over the lower edge of the slot of the drum, the rounded edge 40 of the slot 39 preventing too sharp a bend being given. To retain the stud in its half-rotated position, so as to be ready to receive the end of another piece of wire, I provide a detent-spring 41, (see Figs. 6 and 9,) secured to the standard and having a rounded end adapted to engage a recess 42 in one or the other side of the stud.

To retain the drum in the proper position, to which it may be turned by the attendant, to insure the entrance of the wire through the hole 37, I provide a bolt 43, mounted in the standard 22 and having abeveled end adapted to enter a recess 44, properly located in the flange of the drum. The rear end of this bolt is formed as a sleeve 45, which receives the pin 46, said sleeve being slotted, as at 47, to

receive a pin 48 in the standard. A pin-andslot connection at 49 permits the sleeve and pin to have a limited relative movement, and a spring 50 is confined between the end of sleeve and the head of pin 46. The outer surface of the head of pin 46 is acted upon by the upper end of lever 26 to hold it in the position shown in Figs. 5, 7, and 8 when the drum is not being rotated; but should the drum stop with its recess 44 not opposite the bolt 43 it is to be rotated by the attendant until the spring forces the bolt into the recess. As soon as the lever 26 is released the bolt is free, and the inclined side of the recess 44 moves the bolt outward as the drum begins to rotate.

The outer end of the drum is provided with movable stops adapted to be projected outward when the drum begins to rotate, so as to retain the coil thereon. Secured to the shaft inside the drum is a hub 51, having levers 52 pivoted to it, the outer ends of the levers being connected, by a yoke-and-pin connection, with rods 53, mounted to slide in ways of the arms33, and the outer ends of said rods being adapted to project outward from the periphery. A sleeve 54 is mounted to slide on the shaft and is connected with the levers 52 by links 55. This sleeve 54 is connected, by means of a pin 56 passing through a slot 57 in the shaft, with a rod 58, which is movable longitudinally within the shaft, said rod being indicated by dotted lines in Fig. 5. The other or inner end of the rod 58 is connected, by means of a pin 59 passing through a slot 60 in the shaft, with the clutch member 25. The construction is such that as soon as the lever 26 is operated to start the drum the rod 58 causes the sleeve 54 to move toward the left, as shown in Fig. 5, and the toggle-links 55 cause the levers 52 to eject the sliding rods 53, so as to prevent the coil from passing off the drum. The drum is slightly tapered, and after the coiling begins and the hook has been formed in the end of the wire, as above described, the said hook begins to travel along the edge of the slot in the drum, said hook being first drawn freely out of the hole 39 in the bending stud 38. When the piece being operated upon is finished, the attendant operates the lever 26 by any suitable means, so as to unclutch the drum-shaft from the driving-pulley, and at the same time the rod 58 is moved so as to retract the rods 53 within the drum, leaving the heavy coil free to be removed.

It is to be understood that the rolls of the four pairs or sets 1, 10, 1, and 10 are so grooved and mounted relatively to each other that as the wire is passed from rolls 1 to 10" it is given four successive reductions to four successively smaller sizes.

Then the two reducing mechanisms,which I have indicated in their entirety by B and B, are employed, it is desirable that there shall be provision for operating the mechan ism Bat a'speed always suflicient to prevent either a pushing or a dragging action on the wire between the two mechanisms. To accomplish this, I connect the pulley b with the shaft 13 by an ordinary form of friction-clutch, which is automatic in its action, according to the resistance to the power afforded by the belt-pulley. This clutch I have indicated at in Fig. 1, partly by full lines and partly by dotted lines, and have not deemed it necessary to illustrate or describe it in detail, since any of the Well-known automatic clutches may be employed.
