i Applioation filed June 27, 1889. Serial No, 315,693. (No model.)

To all wir/0717, it may concern:

Be it known that I, BLASIUS BEGUZ, a subject of the Emperor of Austria-Hungary, re-

siding at Feistritz', in theDuchy of Carinthia/ and Empire of -Austria-I-Iungary, have invented certain newand useful Improvements in VVire-Drawing Apparatus; and I do hereby declare the following to be a full, clear, and

'exact description of the invention, such as is apt to take place among the several lengths of wire, so that the drawing operation has to be frequently interrupted, thereby reducing the rate of production of the machines.

According to the present invention the above inconvenience is obviated by arranging between the drawing-cylinders and the dies intermediate guide rollers or pulleys, so that the wire passing from the die to' the drawing-cylinder is made to pass over such intermediate rollers and then again over the cylinder, from which it then passes t the next die. By this Ymeans a sufficient intervalis provided between the separate contiguous wires passing through the dies to eflectu` ally preventany entanglement thereof. The drawing-cylinders may for this purpose be either cylindrical or conical, with suitable grooves or` divisions, or they may be smooth, inwhich latter case the intermediate guiderollers receive a longitudinal movement in the direction of the axis of the drawing-cylinder in order to prevent any Wear of the surface of the latter. The axes of the intermediate rollers are furthermore provided with devices which counteract the tensional strain of the wire and prevent the intermediate roller from bearing againstthe drawing-cylinder.

The accompanying drawings showvarious arrangements for carrying out the abovedescribed invention.

Figures l and 2 show, respectively, a diagrammatic elevationand plan of the arrangement with the drawing-cylinder. Fig. 3 is a side view, and Fig. 4, is a plan, showing a modification of the machine provided with a conical drawing-cylinder. Fig. 5 is a side view, andFig. 6 is a plan, showing a modification of the machine provided with a smooth ribless drawing-cylinder. Fig. '7 is a side view, and Fig. 8 is a plan, showing a modification of the machine having a drawing-cylinder provided with a series of disks or ribs for separating the loops of wire. Fig. 9 is a side view, and Fig. 10 is a plan, showing a modification .of the machine provided with drawing-cylinders mounted on vertical shafts.

In Figs. l and 2 the wire passes from the reel F, which may dip into a pickling-bath, over the guide-roller C, which has angular grooves C', to the die fixed in the frame B, from which it passes to the drawing-cylinder D, driven by the main shaft of the machine, and which dips in a suitable manner into the bath Z, lled with pickling-liquor. This drawing-cylinder D is alsoformed with a series of projecting ribs, flanges, or circumfer- -ential partitions, which .form angular grooves D, and the wire passes from -one of these grooves D to the intermediate guide-roller E,which, as before described, forms the main feature of this invention. This roller is carried loose on an axis situated parallel to the axis of the drawing-cylinder D. These intermediate guide-rollers E also have angular grooves E', and several of these rollers being situated side by side loose on their common axis it will be seen that they may revolve in contrary directions independently of each other. From these intermediate guide-rollers the wire again passes over the drawingcylinder D, where it enters a groove D', next to the groove from which it before passed to the guide-roller. In this groove it is carried through the pickling-liquor, and thence over the guide-roller C to another drawing-die. From this it again passes to the drawing-cylinder D, and'thence over the intermediate guide-roller E, and so on as many times as there are dies through which the wire is to be drawn. Lastly, the wire passes as a finished product from the drawing-cylinder onto the winding-drum A, which is driven direct from the driving-shaft. In order to neutralize the bending strain produced by the wire tending IOO to force the drawing-cylinder D andthe intermediate guide-roller E toward each other, the axis of the latter carries one or more lcontact-rollers G, which bear against a corresponding surface on the cylinder, and thus prevent any contact between the intermediate roller and the drawing-cylinder. As in this case each wire runs in a separate V- groove on the drawing-cylinder, no confusion or entanglement of the several coils of wire during the process of drawing can occur. The axes of the drawing-cylinder D and intermediate guide-rollers E are in this ease assumed to be supported on each side; but in order to facilitate the coiling on of the wire in the rst instance these axes may be arranged in such a way that they are corbeled out. The bearings are both situated at one of the frontal sides of the cylinder and guide-rollers, and have the driving-gear for the drawing-cylinder situated between them.

The arrangement shown by Figs. 3 and 4, respectively in elevation and plan, chiefly differs from the foregoing in that the drawing-drum D, with its angular groove D', is not cylindrical, as before, but conical or tapering. In this case the axis on which are mounted the intermediate guide-rollers E and the Supporting-roller G is not parallel to that of the drawing-drum, but parallel to the conical surface thereof. The course taken by the wire is the same as before, withthe single difference that before it passes from the drawing-drum over the guide-roller C to the next drawing-die it is led over the lower guide-roller ll, dipping into the picklingliquor contained in the vessel Z below, so that the wire before each passage into the next die is carried through the pickling-liquor; also, in this .case the free support of the axes of the drawing-drum and the intermediate guide-rollers referred to in the previous arrangement may be adopted.

'In the arrangement 'shown at Figs. 5 and 6 the drawing-drum is formed without the before-described angular groove, being made perfectly smooth and cylindrical.V In order also in this case to prevent entanglement of the several windings of the wire, the intermediate guide-rollers carried on an axis parallel to that of the drawing-drum D are provided each with two grooves E. Over one of these grooves the length of wire is passed, which, coming from the drawing-die, passes onto and round'the drawing-drum, so that this groove serves to guide the wire always in one direction. The second groove of each intermediate guide-roller serves to guide the wire before it passes a second time round the drawingdrum from which it then passes over the guide-roller C to the next drawing-die. By this arrangement no entanglement of t-he windings of wire can take place. In order in this arrangement to prevent any wear of the smooth cylindrical drawing-drum, for which generally very hard material is used,

the axis on which the intermediate Vguide-- rollers E are mounted receives a slight reciprocating motion in the longitudinal direc tion, so that by this means also the wires passing over the drawing-drum D receive a cont-inuous to-and-fro movement in the direction of the axis of the drum, thereby causing any wear to take place uniformly on the entire surface of the drum in the longitudinal direction. The means for imparting this toand-fro motion to the axis of the intermediate guide-rollers E may be variously modified.

In the drawings is shown, by way of example, an inclined disk or cam L, which is actuated by the drawing-drum or any other rotating part of the machine, and which bears against a suitably-formed head M, iixed on the end of the axis of theintermediate guiderollers E, vthereby imparting to such axis a motion in one direction, while the return mo tion is effected by a spring K.

In Figs. 7 and 8 is shown an arrangement similar to that just described, with the principal difference that, in order to still further prevent any entanglement of the wires, there are provided on the cylindrical drum D thin partition-disks D2, which are situated between each two coilings of the wire on the drum, so that these partition-disks also keep separate those windings of the wire that are not led round the intermediate guide-rollers E; also, in this case a reciprocating motion is imparted to the intermediate guide-rollers, and consequently, also, to the wires in the direction parallel to the axis of the drawing-drum.

The above-described arrangement of the bearings for facilitating the winding on of the wire can also be adopted in this arrangement in such manner that the apparatus is provided with two symmetrically-arranged drawing-d ru ms, the'space between the two being utilized both for the driving-gear of the drawing-drums, as also for the arrangement for imparting a reciprocating motion to the axis of the guide-rollers and for the bearings of the axis.

Figs. 9 and 1Q show an arrangement in which the drawing-drums are mounted on vertical axes, those before described being assumed to be horizontal. With thisarrangement the two symmetrically-arranged drawing-drums are formed conical, and are also provided with angular grooves, which are not shown on the drawings on account of the smallness of the scale. The intermediate guide-rollers E are each mounted on a separate axis, all the axes of the guide-rollers belonging to one drum being mounted in a frame N, which is connected to the two supports O O of the bearings for the drawingl drum D, so that a line drawn through the center of -all the intermediate guide-'rollers lies parallel to the conical surface of the drawing-drum instead of to its axis. The guiderollers C, having angular grooves, are formed 1n this caso with varying diameters. rlhe IOO IIO

wire passes from the reelF over small guiderollers fr onto the first lower groove of the right-hand drawing-drum D. It then passes over the smallest of the guide-rollers C, at the same time dipping int-o the vessel Z, containing pickling-liquor, and passes thence to the rst drawing-die situated in the left-handv frame B. From there it passes to the lower groove of the left-hand drawing-drum D, and passes around the same and around the intermediate guide-rollers E twice. It is then led over the second smallest guide-roller Cof the front set, and in passing around the same dips into the pickling-liquor, from which it passes to the drawing-die situated in the right-hand frame B. From there it passes to the second groove of the right-hand drawingdrum D. After having passed twice around the same and around the intermediate guideroller E the wire passes overa guide-roller C, through the pickling-liquor, and again to the left-hand drawing-drum D, and'so on until it has passed through all the several drawingdies. This motion of the wire is indicated on the drawings by the numerals l to 22. The two symmetrical drawing-drums D, acting together, are driven by one and the same shaft F and bevel-gear Q Q.

What I claim isfv l. In a wire-drawing machine, the combination, with a revoluble drawing-cylinder, of a series of guide-rollers journaled on a shaft, a series of dies for gradually reducing the wire arranged between the said rollers and the cylinder, and a series of intermediate guide-rollers journaled between said dies and the cylinder for the wire to pass around, substantially as set forth.
