SOCKET FOR FASTENING WIRE ROPE. No. 427,302.
Patented May 6, 1890.
NITED STATES FRANK o. DUMAs, on NEW YORK, N. Y.
SOCKET FOR FASTENING WIRE ROPE.
SPECIFICATION forming part of Letters Patent No. 427,302, dated May 6, 1890.
Application filed June 27, 1888. Serial No. 278,345. (No model.) I
To all whom it may concern:
Be it known that I, FRANK C. DUMAS, of New York city, in the county of New York and State of New York, have invented a new and useful device for fastening wire rope by means of a screw-socket with hollow core and metal plug to hooks, either swivel or stationary, clevises, or any other fastenings of wire rope where eye splices or sockets are now usually employed, of which invention the following is a specification.
This invention dispenses with the necessity of splicing loops or eye-splices in wire ropes to join or attach them for mechanical purposes, and the following is a clear and ac. curate description of said invention.
Figure 1 is a screw-socket having a hollow chamber, which is provided with a screwthread and fitted to allow the hollow cylindrical core Fig. 2 to be screwed into it when in operation. Fig. 3 is a sectional view of the cylindrical core shown in Fig. 2. Fig. 4 is the plug of lead or other soft metal used in the general form of an inverted cone. Fig. 5 is a further sectional view of the same cylindrical core with a wire rope passed through it, with the strands of the rope unlaid at its end, and showing the insertion of 1 the plug, Fig. 4. Fig. 6 is the socket, Fig. 1,
with the cylindrical core with rope and plug, as shown in Fig. 5, screwed firmly into the socket, Fig. 1, against the cushion or plate A.
Similar letters refer to similar parts of the apparatus.
My invention consists of a hollow metal cylinder, Fig. 2, provided with a screw-thread around its outer surface to fit the screwthread in the socket, Fig. 1, and provided with a cap a, which may beheld in a wrench. This core or cylinder is hollow, provided with a longitudinal bore 13 from end to end, through which a rope D may pass, and this bore or hollow is expanded as it approaches the upper end 0, in form to receive the c0ne-shaped plug, Fig. 4, to be inserted into the expanded bore 0 of the core or cylinder, Fig. 3. The wire rope D is passed through the cap end of the cylinder with its strands unlaid and parted around the side of the expandedbore c. The
socket, Fig. l, with hollow chamber, is stopped and sealed at'its upper end at A by a plate or cushion of metal.
With these elements my invention is operated as follows: The wire rope, which is to be attached to a hook, clevis, or other mechanical attachment, (the latter being provided with a screw-socket, as above described,) is passed through the cap end of the bore in the cylindrical core, Fig. 2, as shown in Fig. 3, and the strands of the rope E E are unlaid, as shown in Fig. 5, around the sides of the expanded bore 0. Then the plugor wedge, Fig. 4, of lead or other soft metal, is inserted into the top of the core and firmly hammered into the expanded partof the core, and over the base of the wedge or plug, Fig. 4, the unlaid strands and wires of the rope E E are then folded, and by hammering or other force these wires are pressed firmly around the plug. The socket, Fig. l, is then screwed down firmly over the core, as shown in Fig. 6, until the plate or cushion A is firmly set against the plug, and the wires E E are folded over the plug or wedge. Thus operated this plug or wedge will serve to hold and confine the wire rope firmly within the core, as described, and forms a servicable, cheap, and novel substitute for the prior methods of attachments by means of eye and loop splices in wire rope.
Instead of inserting the metallic plug by power, as described, the same may be run into the core 0 in the form of molten lead or other metal; but for ordinary use the manner described herein has been found sufficient.
Having thus described my invention and its operation, I claim as new and desire to secure by Letters Patent 1. In a fastening for wire ropes, the hollow cylinder or core having a screw threading externally and provided with an expanded bore c, fitted to receive the plug or wedge, Fig. 4:,
and a wire rope D, grasping the said plug or Wedge, and said core screwed into the socket, Fig. 1, as and for the purpose described.
2. The combination of the hollow cylinder or core having a screw-thread around its outer surface and a longitudinal bore expanded at its upper end to receive the wedge or plug,
with the Wire rope inserted through said bore the purpose of holding and fastening a Wire and its strands unlaid and engaged with and rope in combination, as described. grasping the Wedge, which is forced into and among the unlaid strands of the wire rope un- 5 laid around the expanded bore of the cylinlVitnesses:
der, and the said cylinder then screwed into .TAS. B. KILSHEIMER, a socket firmly against the cushion-plate for XVM. D. UTLEY.
