APPARATUS FOR OPENING OUT MULTIPLE-WIRE CABLE OR THE LIKE APPLICABLE TO THE FORMATION OF BLOCKS 0N SUCH CABLE.

Specification of Letters Patent.

Application filed January 10, 1911. Serial No. 601,902.

To all lwho/ml it may concern.'

Be it known that I, ARTHUR DOXFORD, a subject of the King of England, residing at Sunderland, Durham, England, have invented certain new and useful Improvements in Apparatus for Opening Out Multiple-Tire Cables or the LikeApplicable to the Formation of Blocks on Such Cables, of which the following is a specification.

This invention is for improvements in or relating to apparatus for opening out multiple wire cable or the like applicable to the formation of blocks on such cable.

The apparatus is primarily intended to assist in the formation on elevator cables of the blocks that constitute the Subject-mattei' of my application Serial No. 601,901, filed January 10, 1911, but the same apparatus maybe used for other purposes in which a block or other part is to be connected to a stranded cable or the like by casting.

According to one feature of this `invention, there is employed with a ixed vise, or other gripping device, a rotatable grippingl device that is opposed to the first for the purpose of holding the cable and opening out the wires or strands by twisting it in the direction opposed to the lay of the wires or strands, as described in the specification above referred to.

In conjunction with the two gripping devices, means may be employed for maintaining the length of cable that lies between one portion that has been opened out, and the next portion that is to be thus treated, in an extended state, so that the length of cable between one opened out portion and that next to be formed, may be adjusted to a predetermined length.

Another feature of the invention consists in employing` with the gripping devices spacing means situated between the fixed vise and a mold that for the purpose of casting blocks is placed around that part of the cable previously opened out.

By maintaining the length of cable that is being handled and parts of which are being treated in an extended state and providing spacing means between the fixed vise and the mold for casting the block, the blocks may be all placed at accurate distances apart, which is of great importance if they are to engage the driving wheels of the elevator, or coperate with other mechanism.

Means may be provided for maintaining in an extended state that portion of the eable which lies on that side of the mold remote from the fixed vise, and further spacing means may also be employed between the mold and the block which has been previously cast.

The invention may readily be employed in connection with multiple wire cables of the kind in which every wire is wound in one and the same direction, one on top of another, as if the finished rope were intended to form a strand only of a larger cable. Obviously, however, the invention may also be applied to other kinds of cable.

In the accompanying drawings-Figure 1 is a longitudinal section through a machine constructedaccording to this invention; Fig. 2 is a plan of the same; Fig. 3 is a section on the line of Fig. 2; Fig. 4; is a section on the line L1--41 of Fig. 2; Fig. 5 is a section on the line 5 5 of Fig.V 2; and Fig. (3 is a section on the line 6-6 of Fig. 2.

Like letters indicate like parts throughout the drawings.

The apparatus is carried by six pedestals A supported upon a base A1. Upon the left-hand pair of pedestals is a casting B having in it a U-shaped recess B1 open at the top. Two jaws O C1, each having a central groove are placed face to face and held together by bolts and nuts C2. The jaws have a journaled end C3 which lies in the U-shaped recess B1 of the casting B and a wedge B2 passing through orifices in the casting extends across the recess above the journaled end so that the jaws can rotate in the recess but cannot be lifted therefrom.

Patented Sept. 24, 19.12. Y

One of the jaws has laterally extending arms D whereby they may be rotated.

Carried on the two right-hand pairs of pedestals is a table composed of three sections E, E1, E2 held together by longitudinal side members E3. These members are flanged as at E3X and may be bolted to the pedestals. The three sections are interrupted by gaps or spaces in which certain operations, hereinafter described can be performed and a third interruption or space occurs between the section E and the casting B.

On the upper face and at the left-hand end of the table-section E is a gripping jaw F clamped to the table by bolts and nutsv F1. The table has a central longitudinal groove and the jaw F has a corresponding groove and is let into the surface of the table so members E2.

that it may grip the cable when laid in the groove on the table. The left-hand end of the table-section E therefore constitutes a jaw-piece F2 that coperates with the jaw F after the manner of a pair of vise-jaws and these jaws are opposed to the jaws C C1.

To the right of the jaws F F2 and on the upper face of the table-section E is a clamping plate G. This is hinged at G1 and is not grooved but lies over a longitudinal groove in the table section E. The free end of this clamping plateA is secured by a handled nut G2 carried on a hinged screwthreaded bolt G2. The plate G is recessed at G4 to allow the bolt G3 to swing into and out of the fastening position without removing the nut G2.

Between the table sections E and E1 a space H is left to receive a two-part mold or casing J J1 which is secured in endwise position by a wedge J2 and in vertical position by wedges J 2 driven through the The table section El carries a second clamping plate Gx which, with its associated parts is practically the same as the clamping plate G and its parts and therefore need not be described in detail.

A second space H1 is provided between the table sections El and E2 for the accommodation of another two-part mold or casing held in place by wedges as already described with the mold J J1.

The operation of this machine is as follows r-The clamping plates G GX are swung back and the upper vise jaws C and F are removed so that the cable can be laid along the center of the machine entering t-he grooves in the bottom vise jaws C1 and F 2; all the table sections E E1 and E2 are also provided with a central longitudinal groove to receive the cable. The jaws C and F are now placed in position and the securing nuts screwed home so that the cable is firmly gripped at these two points and the wedge B2 is placed in position to prevent the aws C C1 from riding outof the casting B. The jaws C C1 are now rotated by means of the Harms D in a direction opposite to the lay of the cable and as the jaws F F2 are stationary and hold their portion of the cable firmly. the cable will be bird-caged or` opened out as shown at X1. This having been done, the jaw F is removed and the jaw C removed or loosened so that the cable can be fed forward until the part X1 is brought to the space H. A two-part mold or casing J J1 such as described in my patent specification above referred to is then placed around the part X1 and secured in endwise position by the wedge J2 and in vertical position by the wedges J3. The two parts of the mold may be temporarily held together in any convenient manner. The clamping plate G is now swung down over the cable and secured by its nut and bolt G2 G2 and the jaws F and C are again made to grip the new portion of cable. It will be seen that the clamping plate insures that vthe portion of cable lying between the jaw F and the mold J shall be retained in an extended state so that when the jaws C C1 are again rotated, to bird-cage the second portion of the cable, this second portion shall lie at a predetermined distance from the mold surrounding the first portion. While bird-caging the second portion, the molten metal is run into the mold so that a solid block is formed in and around the first bird-caged portion as described in my patent specification already referred to. The cable is now again advanced by releasing the clamping plate and jaws C and F and .the newly formed block with the mold or casing around it is brought to the space H1, the second bird-caged portion being brought to the space H ready to have a block formed upon it. if the mold is intended to form the final casing for the block it is permanently riveted to the block while in the space H1 but otherwise the mold is removed and a casing substituted and riveted in place at this point.

Preferably the mold or casing is wedged in position in the space H1 as in the space H and the second clamping plate GX is secured down over the cable to hold the portion of cable between the two blocks in an extended state. The riveting of the mold or casing may be effected while a third portion of the cable is being bird-caged and the second portion is having its block cast upon it. The next advance of the cable will carry the finished block with its casing out from the space H1 beyond the apparatus as shown at X2 and the process may be repeated until the required number of blocks has been formed upon the cable.

In some instances it may be more convenient to rivet the casings to the blocks while they are in the position X2 instead of in the space H1. rlhe riveting of the mold or casing would then of course be effected while a fourth portion of the cable was being bird-caged and a third portion having its block cast upon it.

Preferably the jaws C C1 and F F2 only grip the cable close to the points where the opening out or bird-caging is to be effected.

It will be understood that the apparatus described with reference to the drawings is only given by way of example as many modifications may be made in detail without departing from the spirit of the invention.
