Description
Dec. 13, 1932. G. R. LUNT APPARATUS FOR WRAPPING CABLE Filed Jan. 4, 1932 Patented Dec. 13, 1932 UNITED STATES PATENT 4OFFICE GORDON R. LUNT, 0F DES MOINES, IOWA, ASSIGNOR TO PITTSBURGH-DES MOINES STEEL COMPANY, OF DES MOINES, IOWA, A CORPORATION APPARATUS FOR WRAPPIN G CABLE Application lfiled. January 4, 1932; Serial No. 584,694.
The object of my invention is to provide a simple and inexpensive apparatus for wrapping cable.
With this and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawing, vin which:
Figure 1 is a perspective view of a length of cable showing my apparatus in position for performing the wrapping, operation.
Figure 2 is a front elevation of the appara-tus.
Figure 3 is a side elevation of the same.
Figure 3a is a detail, sectional view showing a slightly modified form of my device in t `which the shells are detachable; and
Figure 4 is a detailed, sectional view taken on the line 4-4 of Figure 2.x
In various kinds of construction work, it is the practice to use main cables made of several secondary Cables, each of which is composed lof numerous strands of individual, galvanized steel wires or the like. VThe wires of the secondary cables are usually twisted together. The secondary cables composing the main cable are usually straight rather than twisted and unless they are wrapped in some way, one secondary cable chafes upon the other, thusdestroying the galvanizing thereon, causing wear and so on. The secondary f cables may sometimes tend to separate. All
this chaiing and separation of the secondary cables is yharmful and considerably shortens their lives. It is therefore desirable to provide some means for wrapping the main cables after l they have been put in place. Y
I have provided a very simple apparatus by which this wrapping operation may be r done. The wrapping must be done with comparatively heavy wire and, of course, should be done with a uniform and desired number of turns to the foot or the yard.
By means'of my apparatus, the wrapping can be conveniently done and the proper number of turns per foot may be uniformly secured.
In the accompanying drawing, I have shown a main cable, indicated generally by the reference character A, comprised of a number of secondary cables I have shown in Figure 1 a section of main cable, which at one point is gripped by a suitable clamp 11. A cable of this kind may be used for instance in a suspension bridge and the clamp may be connected by means of a rod 12 with the bridge structure below.
My improved apparatus comprises a frame or spool holder, comprising two parallel spaced side members 13 which at one end have portions 14 inclined toward each other. At their adjacent ends, the portions 14 terminate in projecting parallel' portions 15 spaced from each other and fastened to the outside of a semi-cylindrical shell or the like 16 as by welding.
` A `heavy rod or the like 17 is extended through the arms 13 and has on one end a head 18 like the head of a bolt and has its other end threaded as at 19 to receive a nut 20 and a lock nut'21.
One of the arms 13 may be provided with lugs 22 adjacent the head 18 to prevent the turning thereof.
Fastened to the inner faces of the'arms 14 are metal discs or'the like 23, through which the rod 17 extends.
Detachably fastened to the inner faces of the discs 23 by means of bolts, rivets or the like 24 are frictiondiscs 25 of fiber or other suitable material.
The wire 26 is preferably wound on a spool B having the discs 27 at its ends. The spool has a bore and may be mounted on my frame, and for this purpose, the rod 17 is removed, the spool is put in place, and the rod is then inserted through the frame members 13 and the spool as shown for instance in Figure 2.
The nuts 2() and 21 may be adjusted for regulating the friction imposed by the discs 25 on the spool. A rod or the like 27a is extended through the handle members 13 at their ends farthest from the shell 16 and is provided with a head 275 and a threaded end 27o, which latter receives the nut 27d. Y
Onthe rod 27a: between the arms 13 is the loosely rotatable sleeve or the like 27e. The rod 27a and sleeve 27 c form a handle by VVwhich the workmen may manipulate my apparatus. Y
The shell 16 is provided on its interior with regularly spaced grooves 28of proper .size-to receive the wire 26 and arranged to form parts of spirals. are spaced apart the proper distance for placing the desired number of turns of the wire on the cable.
In Figure 3a is shown a slightly modified form of the device in which the shell 16a similar to the shell 16 is detachablymounted on the frame by means of bolts 16?) having their .heads sufficiently countersunk in the shell.
In preparing to wrap a cable, the wire 26 is drawn from the spool around the outside of ythe'shell 16.
The portions 15 of the frame members 13 yare connected near their outer ends by a cross member 29,'as shown best in Figure 4, and the wire is threaded between the members 15 and between the member 29 and the shell 16.
' The outside of the shell is provided in line with the space between the members 15 with agroove` 30 to guide the wire. The free end yof thcfwire is then fastened as for Yinstance to the clamp 11 andthe wire is given a couple 'of turns around the cable.V These turns may be Vadjusted manually until theyare properly spaced, so that they will iit a couple of the grooves 28.
For instance, if the cable A shown in Figure 1 is to be wrapped from the clamp 11 toward the left, the shell 16 is put in position so that the two right-hand grooves 28, as shown in Figure 2, receivetwo turns of wire on the cable. To startA with, the apparatus 1s slowly rotated around the cable A in the direction indicated by the arrow a in VFigure Il, until the wrapping wire becomes taut.
Thereafter, two workmen can continue to swing the apparatus around the cable at a greater rate ofv speed for performing the wrapping operation. The braking apparatus already mentioned will operate to maintain the wrapping wire taut and the wire can be quite rapidly wrapped on the cable.
The groove 30 is spaced from the adjacent .grooves 28, so that after the apparatus fol-V lows the last two turns of wire on the cable, the wire traveling through the groove 30 The successive grooves -28/ will make another turn of wire on the cable properly spaced from those already thereon.
By means of this apparatus, a regular and uniform wrapping can be secured.
In order to make the wrapping more convenient and accurate, I preferably use detachable clamp members for holding the secondary cables 10 closely together. Such adetachable clamp member is indicated at C in Figure 1. It comprises a couple of handles 31, having at one end curved receiving members 32, which at their extreme parts have ears 33 which receive a pivot pin 34. By pulling the handles toward each other, the cables 10 may be tightly gripped and brought closely together.
A yokef is pivoted to the outer end of one handle 31 and is adapted to lit over the other handle 31 and-tocoact with notches 36 therein for locking the clamp member C in place 4on the cable.
The tension on the wire may be regulated by loosening or tightening the nuts 20H21 for 'thus controlling the friction between the discs '25 fixed to the frame and the discs 27 forming parts of the wire spool.
' After 'the wire on one spool has been used,
the loose end is fastened on the cable in any suitable way, or may be fastened to the wire on another spool, where that is desirable for continuing the wrapping.
It will be obvious that by varying the size of the grooves 28, my apparatus may be adapted for use with wires of different diameters. Likewise by varying the spacing of the grooves 28 with relation to each other and with relation to the groove 30, my apparatus may be adapted for putting different numbers of turns of wire on the cable per foot.
The shell 16 may be made detachable if desirable for adapting one apparatus for use with vdifferent sizes of wire or for putting different numbers of turns per foot on the cable.
It is obvious Vthat numerous changes might be made in the details of the construction and arrangement of parts of my improved wrap,- ping apparatus, and it is my purpose to cover by my present application and the patent to be issued thereon any such modifications in structure or use of material or employment of mechanical equivalents, which may be within the scope of my invention and my claims.
I claim as my invention:
