Specification 01 Letters Patent. Patented July 111, 1922.

Application as December a, 1920. Serial No. 427,855.

To all whom it may concern:

Be it known that I, ALBIN E. AimnRsoN, a citizen of the United States,'a-nd resident of Oakmont, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Wire-Rope Machines; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to machines for making wire ropes and cables and it has for its object to provide a machine of the character indicated whereby a large number of wires may be combined to form rope or cable, and whereby the floor space required for the machine may be materially reduced as compared with prior machines for the same pur- P In my application for Letters Patent filed April 17, 1920, Serial No. 374,597, I have described and claimed a machine of the same general type as that to which my present invention relates. The machine shown in that application consists of a single flier frame carrying a plurality of individual bobbin frames, each bobbin frame operating to form a twisted strand and the several strands from the individual bobbin frames being thereafter combined into a larger cable. The individual boblbin frames shown in my earlier application consist of parallel bars of considerable length between which the several bobbins are journaled. Although this construction provides for a considerable reduction in floor space over machines of the prlor art, the machines are rather long, especially when making cables composed of a very large number of individual wires.

My present invention aims particularlyto secure even greater compactness in the individual bobbin frames by arranging the bobbins circularly around the axis of rotation of each bobbin frame instead of in sideby-side relation. In addition, my invention provides for tensioning the wires and the twisted strands in an improved manner.

A machine constructed in accordance with my invention is shown in the accomp drawing, in which Fig. 1 is a longitudinal still of necessityanying elevation, with parts broken away for the sake of clearness; Fig. 2 is an end elevation of a portion of one of the flier frames showing the individual bobbin frames in detail and their operating gearing diagrammatically; Fig. 3 is a longitudinal sectional view through one of the individual bobbin frames; Fig. 4' is a sectional view taken axially through one of the tensioning sheaves; and Fig. 5 is a lon itudinal sectionalview through a modified orm of bobbin frame.

Referring to the drawing, the numeral 2 designates a suitable base and 3 designates bearing blocks which support antifriction rollers 4 which serve as a cradle for a flier frame comp-rising spaced spider-plates 5 and 6. A shaft 7, driven from any suitable source of power through a pulle 8 extends centrally through the spider pliltes 5 and 6 and is ke ed thereto. The plates 5 and 6 are secure together by means of bolt rods 9.

Mounted in the flier frame between the spider-plates 5 and 6 are a series of individual bobbin frames 12, the machine shown being provided with ei ht of these bobbin frames. Each bobbin I rotate on its own axis and to this end each bobbin frame has a journal 13, as shown in Fig. 3, extending through an opening 14 in the spider-plate 5, and to the outer end of the journal 13 is secured a pinion 15. Each pinion l5 meshes with a gear wheel 16 on a stub shaft 17 secured in the spider plate 5, and all of the gear wheels 16 mesh with a central gear wheel. 18 which loosely surrounds the shaft 7 and is-held against rota-.

tion by any suitable means, not shown.

he inner end of each individual bobbin frame 12 is provided with a trunnion 20 which fits within a bearing 21 in the spider ame is mounted to axis of rotation of the bobbin frame 12, the

bobbins in each set being staggered with relation to the bobbins in the other set. The flanges 25 may all be formed in a single casting or the may be pressed from sheet metal or otherwise fabricated. It will be observed that this arrangement wherein the bobbins. are arranged circularly around the axis of rotation of the bobbin frame, provides for ei ht bobbins in the same space, lengthwise of the bobbin frame, which is occupied by two bobbins. The resulting saving in the floor space required by the machine is thus apparent.

Fig. 5 shows a modified form of bobbin frame carrying twelve bobbins instead of eight. In this-case the flanges 25 nearest the trunnion or twister 20 are extended as shown at 42 to receive four additional bobbins, and the wires from the bobbins nearest the twister are led off from the tops of the bobbins-as shown at 43, while the wires from the bobbins directly below these forward bobbins are led off from the bottoms of the bobbins, as shown at 44. This prevents the two wires from the adjacent 'bbins from interfering with each other. For this form of bobbin frame the twister is of course provided with twelve openings instead of eight.

The bobbins 26 carry the wire from which the cable is to be formed. When the ma chine here described is used as an inde endent unit the wire from one of the b0 bins is led through the central opening 22 in the trunnion 20 forming the core around which the wires from the other bobbins, which are led through the openings 23, are wound by the indiv1dual rotation of the bobbin frame produced by the pinion 15 and the gear wheel 16 which rolls upon the stationary gear wheel 18.

- Supported upon a. bracket 27 adjacent to each of the. trunnions 20 is a clamp 28 through which the twisted cable from each individual bobbin frame asses, said clamp consisting of u per and lower clamping members 29 an 30 which are secured together by means of a bolt 31. The bracket 27 is also provided with parallel arms 32 within which is journaled a pin 33 carrying a guiding and tensioning sheave 34 around which the twisted strand or cable 35, coming from the clamp 28, is given a complete turn, as shown in Fig. 4. The pin 33 is provided at one end with a head 36 and is screw-threaded at its other end to receive an adjusting nut 37 and a lock nut 38. A friction disk 39, suitably of leather, is laced between the head 36 and the adjacent bearing, and a spring 39 is compressed between oneof the bearings 32 and a washer 40 adjacent to the adjusting nut 37. By suitably adjusting the tension of the spring 39 the sheave 34 is given a suitable fricaround the bobbins on guide rollers, as in the machine shown in my earlier application mentioned above.

The strands 35, after leaving the sheaves 34, pass to a twister head 45 journaled in a stationary standard 46 where the strands 35 are laid around a core strand 47 which passes through a central passage in the shaft 7. The finished cable asses around a drum 48 and thence to a suitable reel.

The machine which I have shown and described not only saves a great deal of floor space but is greatly condensed in comparison with cable machines of the prior art and the cost of construction is thereby reduced.

I claim as my invention.
