(Cl. '1-138i 4 Claims. l

Another feature of the invention is the provision of a die having radially disposed strand engaging tool pieces which cooperate with each other under hydraulic pressure to form a plurality of wire strands into a wire rope, having a uniform cross sectional diameter, the strands, of which are tightly compressed.

A further feature of the invention is the provision of a die comprised of a plurality of rope engaging tool pieces, each of which is automatically and synchronously adjustable through the medium of a hydraulic pressure controller from a master hydraulic unit under the 'command of an operator.

A still further feature of the invention is the provision of a die which is simple in construction, reliable and efficient in operation, and inexpensive to manufacture and install.

With these and other objects in view, the invention consists in the features of construction, and the combination and arrangement of parts, all as will be hereinafter fully described, illustrated in the accompanying drawings, which dis` close a preferred embodiment ofthe invention, and pointed out in the claims hereunto appended.

In the accompanying drawings- Figure 1 is,an elevation of a die constructed in accordance with the invention.

Figure 2 is a fragmentary plan view thereof, l

adjuncts of the same being partly in section.

Figure 3 is a fragmentary view similar to Figure 1 looking toward the opposite side thereof.

Figure 4 is a sectional view taken on,the line 4-4 of Figure 2 looking in the direction of the arrows.

Figure 5 is a perspective view of one of the work-engaging tools of the die.

Figure 6 is a perspective view of one of the tool plungers removed from the die.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, the die conring or line 24 is a m that the tool pieces stituting the present invention comprises a substantially hexagon-shaped hollow head designated generally at erably of steelclosed at one end by an end plate I I which at the outer periphery thereof is shaped to correspond tothe head and is detachably secured in place by fasteners I2. Interiorly of body I0 and integral therewith is a core I3 which extends 'the full length of the body and which is formed with radially disposed guideways I4 which open into each other at its longitudinal central axis. The grouping of these guideways corresponds to the spoke formation in a vehicle wheel and in their lengths are co-extensive with the longitudinal extent of the body Ill. v Working within the guideways I4 and coextensive therewith are work engaging tools or tool pieces I5, each having an outwardly tapered concave working face I8 coextensive with the length thereof.

Mounted exteriorly on the body I0 on the central portion of the flat external faces I1 thereof are a plurality of plunger cylinders I8, each having a base flange I9 attached by fasteners I9' to the face I1. Recipi'ocatingly mounted interiorly of each such cylinder is a plunger 2li having a reduced fulcrum stem 2l making contact with a cup or ball fulcrum 22 the cup 23 therefor being counterseated in an adjacent tool piece I5, which plunger 20 automatically adjusts its associated tool piece I5 in the working of the die as a unit.

Concentrically above the body III is a pressure feed ring or line 24 having inwardly directed radial branches 25 aligned with the cylinders I8 and terminating in nipples 26, while leading to ain feed conduit 21 which extends from a master hydraulic pressure pump unit installed in a rope machine (not shown). The master unit is under the control of the operator of the machine. Uniform hydraulic pressure is transferred to the cylinders I9 through ring 24 for the operation of the plungers 20 therein ,so I5 will approach each other automatic adjustment thereof under pressure for the formation of a wire rope from a group of wire strands (not shown).

The strands of' wire for the formation of the through the wire rope are directed through the circular open way 28 created by the channeled faces I6 of the Vtool pieces I5 and the head A and under pressure hydraulically tool pieces I5 are compressed about the strands of wire passing through and filling the opening 28 thereby compressing these strands into a wire rope body as such 'strands are passed through the die and its vequipment by a rope mak- The plate l ing machine. I has the center hole A, including a, body I0 pref-v 3 29 registering with the way 28 between the tool pieces I5 for the passage of the formed rope from the die. When the wire rope is finished the pres-v sure on the work tool pieces l5 is relieved 4and when these are subjected to pressure the latter is uniform throughout the series of pieces.

The die, by reason of the construction as before described, is susceptible of adjustment to any desired size rope within its range. In the operation of the device the rope is initially passed into the die with all pressure released and when the strands of wire have been initially inserted the operator controls the master unit to put the desiredpressure on the tool pieces l5 for the successful operation of the die vin the wire rope formation. h Y

From the foregoing it will now be seen that there is herein provided a device accomplishing all the objects of this invention, and others, including many advantages of great practical utility and commercial importance.

As many embodiments may be made of the inventive concept, and as many modifications may be made in the embodiment herein shown and described it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense.

What is claimed is:

1. A die of the character described, comprising a head having a plurality of centrally disposed automatically adjustable tool pieces therein grouped to form a strand wire rope-way therebetween, and individual hydraulic plunger means operable upon each of said pieces for exerting uniform pressure thereon throughout the group.

2. A die of the character described, comprising a head having a plurality of radially disposed automatically adjustable tool pieces therein grouped to form a strand wire rope-way therebetween, hydraulic means operable upon said pieces for exerting uniform pressure thereon throughout the group, the last mentioned means includingindividual fulcrum plungers acting directly onvsaid tool pieces at their midpoints.

3. A die of the character described, comprisving a head having a plurality of radially disposed automatically adjustable tool pieces therein grouped to form a strand wire rope-way therebetween, hydraulic means operable upon said piecesfor exerting uniform pressure thereon throughout the group, the last mentioned means including fulcrum plungers acting directly on said tool pieces, and means for exerting pressure on the respective plungers.

4. A die of the character described, comprising a head having a plurality of radially disposed automatically adjustable tool pieces' therein grouped to form a strand wire rope-way therebetween, hydraulic means operable upon said pieces :for exerting uniform pressure thereon throughout the group, the last mentioned means including fulcrum plungers acting directly on said tool pieces, means for exerting pressure on the respective plungers. and a core within the head and having guideways for each ,of said tool pieces.
