FERDINAND PHILIPS, 'OF PHILADELPHIA, PENNSYLVANIA.

MACHINE FOR DRAWING WIRE.

SPECIFICATION forming part of Letters Patent N 651,051, dated June 5, 1900. Application filed June 3, 1898. Serial No. 682,433. (No model.)

subject of the Emperor of Germany, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Machines for Drawing Wire, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

My invention relates to the construction of a machine for drawing wire, and has for its object to simplify and improve the construction of such machinery, and particularly to provide machinery for drawing the wire which will act with greater smoothness and evenness than has heretofore been the case, and thus lessen the tendency to break the wire in the act of drawing it.

The nature of my improvements will be best understood as described in connection with the drawings, in which they are illustrated, and in which- Figure 1 is a plan view of a wire-drawing machine embodying my improvements. Fig. 2 is a cross-sectional elevation taken as on the line 1 1 of Fig. 1. Fig. 3 is a horizontal section taken as on the line 2 2 of Fig. 2 looking upward. Fig. 4 is a sectional elevation taken as on the line 3 3 of Fig. 1. Fig. 5 is a section through the block or drum, taken on the line 4 at of Fig. 1. through the die and die-holder, taken as on the line 5 5 of Fig. 1; and Fig. 7 is a plan view of the drawing-in tongs and attached chain.

A indicates the framing of the machine, which may be of any convenient construction.

13 B are the bearings for the power drivingshaft 0, D indicating a pulley on said shaft by which it is driven.

B is a step-bearing for the vertical shaft H, B indicating a further bearing supported on the upper part of the frame for this shaft.

E is a sleeve secured, as by means of a spline and feather, (indicated at'e,)' to the shaft 0, so as to rotate with said shaft. EX tending out from the end of this sleeve is the disk E, having'a rim E over which fits a flange of anannular disk E which'by means of a series of bolts E passing through the disk E, is connected with a series of bent levers E the outer ends of which rest against Fig. 6 is a section therim E while their other arms are connected by links E with a sleeve E in the outer end of which is formed an annular groove E into which extends pins E, attached to the arms of a forked lever E connected in turn to a rock-shaft E to the end of which the clutch-actuating lever E Fig.

2, is attached. Situated between the annu- 6o lar plate E and the disk E is the annular block-face F, attached to one end of a sleeve F, supported upon the shaft 0 and connected by bolts or otherwise, as indicated, with a sleeve F upon the end of which is formed or secured a miter-wheel F3.

The device as described is simplya frictionclutch, by means of which the sleeves F and F connected with the connected miter-wheel F, can be at will either clamped to the shaft C so as to rotate with it or permitted to remain stationary while the shaft 0 is in motion, and .the particular design of the clutch is' not material to my invention, as any equivalent form of friction-clutch may be used with 7 5 substantially the same effect.

The miter-wheel F is in permanent engage ment with a miter-wheel G, having, as shown,

a pitch-line circumference six times that of bevel gear-Wheel F and which should always be of very considerably larger dimensions thanF Said wheel G in turn is secured to the Vertical counter-shaft H, the lower end H of which is stopped in the bearing B and which, as shown, has a partially-squared portion H near its top and the cylindrieal top portion H above said-squared portion. Gentered on the portion H of the Vertical shaft is-the head 1 of the block or drum I, said drum being provided with an upwardly-ex o tending flange I and formed or provided on its under side with recesses 1 (see Figs. 1' and 3,) which recesses in the normal position of the block engage the fingers or arms of the drum-rotating device, (indicated at J which is secured on the squared portion H of the shaft, so that in normal position of the parts the drum or block revolves with the vertical shaft; but by raising the drum slightly, so as to disengage the recess I and the device J, ICO the drum may remain stationary without being entirely withdrawn from the shaft.

Atl Fig. 2, I have indicated a hole or perforation in the lower portion of the drum of of drawing in.

a shape suitable to be entered and engaged by the hook P attached to the joint P',which in turn is connected with the drawing-in tongs P.

At K, I have indicated a vise or gripping device such as is commonly employed with wire-drawin g blocks and by which the end of the wire is clamped to the block or drum after it has been drawn through the die to a sufficient distance.

To a bracket (shown at A) I have indicated as secured by means of a pivot-pin M the die-holding'pl'ate L, having upwardly-extending arms L, between which is placed the die 0, having a number of wire-drawing apertures formed in it and which is clamped in desired position by means of the screw N, working through a cross-bar L connected with the tops of the arms L.

At Q, (see Figs. 2 and 4) I have indicated a brake arranged to act upon the under side of the flange I of the drum or block and connected with a rod or rods Q, working in a bearing 13 said rod and brake being raised into contact with the drum when desired through the pivot lever Q actuated, by means of a link or connection Q by the fcottreadle Q.

In operating my machine the pointed end of the wire to be drawn is inserted through one of the perforations in the die 0 and gripped by means of the drawing-in tongs P, the hook P attached to which tongs is secured to the periphery of the drum 1, as by inserting it in the perforation 1 The operator then by means of the clutch-lever E actuates the friction-clutch, engaging the sleeves F and F with a constantly-revolving shaft 0, so as to cause the gear-Wheel F to rotate with the shaft and to rotate the vertical shaft and the drum or block attached to it, and by this means the wire is drawn through the die to any desired distance and by an even constantly applied force and, moreover, one which by a proper manipulation of the clutch can be brought into operation as gradually as may be desired, thus avoiding all the sudden shocks incident to wire-drawing machinery as heretofore constructed and the consequent very frequent breaking of the wire in the act After a sufficient amount of the wire has been drawn through the block the drawing-tongs are disconnected from the wire and from the drum and the end of the wire clamped to the drum or block by means of the vise K, the machine of course being stopped while this adjustment is made and then started again by means of the frictionclutch without sudden jar or shock, and it will readily be understood that by means of the brake Q the operator has it in his power to check the momentum of the block and connected parts with any desired degree of rapidity after the positive connection with the driven shaft has been severed by releasing the clutch.

It is of the essence of my invention that the intermediate gearing, as shown, consisting of the gears F and G and the friction-clutch connecting gear F with the driving-shaft, should be of a character which in transmitting the motion of the driving-shaft to the drum will naturally reduce speed and increase power and that the friction-clutch member of such gearing should always be applied to a relatively high speed member of the gear mechanism. The importance of this construction lies in the fact that it relieves the frictionclutch of the duty of directly withstanding the full power exerted by the drum or block and in the construction shown imposes on it only one-sixth of this duty, a duty well within the capacity of such clutches, while the full power exerted by the drum has been found to be too great for such clutches as they are now generally constructed and as it is convenient to construct them.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is
