Description

Dec. 31, 1963 E. R. HERRMANN cAPs'rAN FOR FAIRED CABLE Filed Jan. 26. 1961 llllllllllll United States Patent O of New Jersey Filed Jan. 26, 1961, Ser. No. 85,096 1 Claim. (Cl. 254-175.7)
This invention relates to a capst-an for reeling in faired cable.
Where it is necessary to handle a specially shaped cable such as one having a plurality of stranded steel cables and electrical wires` incorporated therein, conventional methods have been found inadequate. When twol or more embedded cables of the same length are wound upon a cylindrical drum in successive layers one cable is caused to follow a longer path at the point where one portion of the cable crosses over the underlying portion making one cable loose, tha-t is, carrying no load, and the other cable tight. Since a drum long enough to store all of the cable in one layer would be too long and heavy to be practical, some other cable reeling in means is necessary.
Accordingly, it is an object of the present invention to provide a capstan for reeling in and storing faired cable which will not impose undue stresses upon any portion of the cable.
Another object of the present invention is to provide a capstan for faired cable which will occupy a mini-mum amount of space.
An object of the present invention is to provide a capstan which will lend itself to a wide variety of cable shapes.
A further object of the present invention is to provide a capstan capable of imparting tensions sufficient to rupture the cable if necessary, which in conjunction with a storage drum permits the cable to be stored on a reel or drum under minimum tension.
A feature of the present invention is its use of an endless takeup chain for transporting the faired cable.
Another feature of the present invention is its use of cams for guiding the endless takeup chain.
Still 'another feature of the present invention is the use of a cable conforming seat on the takeup chain to receive the faired cable without damage thereto.
The invention consists of the construction, combination and arrangement of parts, as herein illustrated, described and claimed.
In the accompanying drawings forming a part hereof is illustrated one form of embodiment of the invention, in which drawings, similar reference characters designate corresponding parts, and in which:
y-FIGU-Rl. 1 is a somewhat isometric vieW partially broken away of a complete embodiment of the present invention.
FIGURE 2 is a somewhat fragmentary isometric view of one of the links of the takeup chain with a second link shown in phantom.
FIGURE 3 is a somewhat diagrammatic view on a reduced scale showing the path of the takeup chain and cable according to the present invention.
Referring to the drawings and particularly to FIG- URES l and 2, 1@ indicates a cfaired cable consisting of rice stranded steel cables 11, 12, and electrical wires 13 embedded Within a resilient faired or streamlined casing 14.
The cable 1li is led into the oapstan over a takeup chain 15 which is formed of a plurality of links 16. The links 16, best shown in FIGURE 2, are made up of blocks 17 which are laterally stepped as indicated at 18 and 19. The smaller stepped portion is provided with a rearwardly projecting member 20 and the larger stepped portion is formed with rearwardly projecting ears 21. The bottom of the blo-cks 17 are out away as indicated at 35 to receive the smaller stepped portion of the next adjacent link as shown in FIGURE 2. A pin 22 slipped thro-ugh the bores 36, 3'7 of the projection 20 and ears 21, secures the links 16 into van endless chain.
The takeup chain `15 is provided on the face thereof with a seat 23j. 'Ilhe seat 23 is cut into the blocks 17 and conforms to the face of the faired cable which is dispos-ed thereon. The seat 23 prevents the cable 10 from shifting upon the takeup chain 15.
The takeup chain is wrapped around a driving drum 24. The drum 24 is cylindrical and provided with a plurality of teeth on its periphery as indicated at 25. The rearward projections 20 and ears 21 are received within the teeth 25 in the manner of a sprocket and chain drive.
A cap member 26, 27, is provided at each end of the driving drum 24 and is formed with a cammed inner surface 28 as shown in FIGURE l. The cams 28 force the takeup chain 15 along the driving drum 24 from one end to the other. The caps 26, 27, also carry bearings Sil -within which the stub shafts 31 of the driving drum 2d are journaled.
After the cable 10 is carried around the driving drum 24- by -the` chain 15, it leaves the said chain and is picked up by a storage drum 32. The storage drum is carried within a support 33 and may be driven in any convenient manner.
On leaving the drum, the blocks 1K7 of the takeup chain 15 are returned to their working position by way of a slack ioop indicated at 34 in FIGURE 3.
In FIGURE 3 there is shown the path taken by the takeup chain 15 and the cable 10. These paths are indicated by the reference numerals 15a and 10a respectively.
Since the chain 15 always starts on the driving drum 24 at the same place and leaves the driving drum at the same place, the cable 1t) will always be in one location. The force necessary to counteract pulling the load down is obtained by the friction force of the cable Wrapped around the driving drum. This force is sufficiently great with the number of wrappings shown in FIGURE 1 to rupture the cable if necessary. The driving drum 24 may be turned by a suitable motor (not shown).
`lt will be apparent that other shapes of cable can be accommodated by the capstan structure hereinabove described merely by varying the shape of the seat 23 to conform to the surface of the cable.
From the foregoing it will be seen that there has been provided a capstan for faired cables which is capable of applying great force to a cable without damaging the wires and stranded cable therein. The capstan assembly permits an asymmetrically shaped cable to be placed upon a storage drum with great accuracy and in a minimom amount of space.
Having thus fully described the invention, what is claimed as new and desired to be secured by Letters Patent of 'the Uni-ted States, is:
A capstan for faired cable comprising a driving drum, a plurality of elongated lteeth on the periphery of the driving drum, an endless takeup chain `Wrapped about the driving drum, a plurality of blocks in said chain, a laterally stepped portion on each of said blocks to provide a small .and a larger portion, the larger stepped portion being cu-t away to receive the smaller stepped 'portion of ithe next adjacent block, means to connect adjacent blocks `into a llexible assembly, tooth engaging projections `extending strom the stepped portions of each block on the chain, cam members at each end of the l driving drum to urge the turns of the takeup chain to move along the driving drum from one end of the said drum to the other, a ycable receiving seat on the face of the talreup chain and a storage drum adjacent the driving drum to receive the faired cable.
