ELBERT H. CARROLL, OF WORCESTER, MASSACHUSETTS, ASSIGNOR TO MASSACHU- WIRE-DRAWING BLOCK.

SPECIFICATION forming part of IlettersrPatent o. 729,541, dated J' une 2, 1903. Application filed July 8,1902. Serial No. 114,733. (No model.)

To @ZZ whom it may concern:

Be it known that I, ELRERT H. CARROLL,

a citizen of theUnited States, residing at,

ing is a specification, accompanied by ldraw-` ings forming a part of the same, in which- Figure lis a longitudinal section on line 1 1 of Fig. 3. Fig. 2 is a similar section on line 2 2 of Fig. 3. Fig. 3 is an end View. Fig. 4 is a plan View showing the application of the wire-drawing blocks to a machine for giving them motion, and Fig. 51's an end view of the same.

Similar reference-figures refer to similar parts in the different views. f I

Theobject is to provide a movable grip to which the end ofthe Wire is attached, fastened to the block in such a manner that it recedes from-the flange as the wire iswound upon the block between it and the ange, thus preventing the wire as it is drawn through the die and Wound upon the block from bunching up upon the block.

Referring to the accompanying drawings,

1 denotes the block, and2 is the block-shaft, i

on each end of which a block is secu red. The blocks are both alike, and only one Will be described. The block 1 is loosely mounted on a spindle 3 and is adapted to be locked to t-he shaft by means of the spring-actuated pin 4,

lwhich has Sliding connection with the block,

having a handle 5 at its outer end, by which it is manipulated, and a block at its inner end adapted to enter an orifice 6, formed to receive it in the collar 7, keyed on the shaft 2. The general form of the block is tapering, it having the usual flange 8 at itsv inner end and being for the most part hollow. The rod 9 extends throughout a portion of the length of the block, and the cross-bar 10 has pivotal Sliding connection with'this rod at one of its ends, the opposite end 11 of said bar traveling in contact with a wear-plate 12 ofhardened steel, as there is Vconsiderable pressure -in friction at that point. A link 13 is hinged to the free end of the cross-bar 10, and pivotally connected with the outer end of said link is a wire-grip 111, said grip having the usual jaws therein between which to receive the Yend of the wire and hold it while the wire is being drawn through the die. There is a die of Cou rse for each block, and in the construction of the machine illustrated the die-boxes 15 l5 are pivoted at 16 16 to the table 17 of the machine and have a joint 18 to allow them to swing upwardly, so that freedom of movement tothe dies is aiorded. Shaft 2 is driven in anyapproved manner-as, for instance,

through the gearing shown in Figs. 4 and 5,

in which a large gear-Wheel 19 is keyedor otherwise secured to the shaft. A main driveshaft 20 and counter-shaft 2l are arranged parallel with the block-shaft 2, and these shafts are providedwith small and large gearwheels 22 and 23, respectively, intermeshed Vwith each other, and shaft 2l is provided with a small pinion 24, which meshes with the teeth of gear-wheel 19,V power` being applied through pulley In this way the desired relative speed of the driveor pulley shaft 20 and the blocks l lis provided foin.'

In operation the end of the wire is clamped in the grip in the usual manner, the crossbar 10 being slid up as near the iange 8 on the block as it will go.

The machinery isset in motion and the wire winds upon the drum close up against the flange, crowding the movable bar 10 with its'grip outward on the block by striking against the lug 10a on one end and the link 13 at the other, as shown in Fig. 2, the grip holding the end of the Wire all the while and receding as fast vas more wire is crowded between the coils formed and the ange 8 until the block has attained its full Acomplement of wire, when the wirev is dis- IOO and a sliding grip mounted to slide axially on the drawing-block to which an end of the wire being drawn is secured, and between which grip and the flange on the end of the block the wire is crowded as the successive coils are wound upon the block, and a wearplate against which the free end of the grip slides, substantially as described.

3. A wire-drawing block having a ange at one end, a movable bar, and a grip having a pivotal connection with said bar and between which and said ange the wireis coiled, substantially as described.

4. The combination with a wire-drawing block, of a cross-bar having at one end a pivotal and sliding connection with said block, and a wire-grip pivoted to the opposite end v of said cross-bar being arranged to be crowded by the wire as it is wound on said block ina direction parallel with the axis of the block, substantially as described.

5. A wire-drawing block having a rod exat one end which extends beyond the surface ot' the block, and a wear-plate against which the free end of the bar slides, and means for connecting an end of the wire to the crossbar, substantially as described.

G. A wiredrawing block having a rod and Wear-plate extending longitudinally thereof, said parts removed some distance from each other, a crossbar having pivotal sliding connection with the rod and bearing upon the Wear-plate, said rod having an outwardly-extending lug at one end, a link pivoted to the other end, and a grip pivoted to thelink, substantially as described.

Dated this 1st day of July, 1902.

ELBERT H. CARROLL.
