J. A. BAZIN, OF CANTON, MASSACHUSETTS.
MANUFACTURE OF BRAIDED CORDAGE, WEBBING, &G.
Specification of Letters Patent No. 20,691, dated June 29, 1858.
To all whom 'it may concern:
Be it known that I, JAMES AMIRAUX BA- ZIN, of Canton, in the county of Norfolk and Sta-te of Massachusetts, have invented cer- 5 tain new and useful Improvements in the Manufacture of Cordage, Webbing, &c., and that the following description, taken in connection with the accompanying drawings hereinafter referred to, forms a full and eX- act specification of the same wherein I have set forth the nature and principles of my said improvements and by which my invention may be distinguished from others of a simi-4 lar class, together with such parts as I claim and desire to have secured to me by Letters Patent.
In the accompanying plate of drawings Figure 1 represents the manner in which the strands are arranged in manufacturing cordage by my new mode and Fig. 2 the relative position of the strands in webbing or flat bands.
In the usual method of making ropes it is necessary to give the yarns a much harder twist than would be essential for binding the separate fibers together in order to compensate for what is taken out by the countertwist of the strands, and it is then necessary in laying these strands up into a rope to give them a much harder twist than would otherwise be required. As it is the tendency of each strand to untwist that keeps them all rmly bound together, a hard twisted rope necessarily requiring an equally hard twist in the strands and thereby causing a constant strain upon all the fibers of which it is composed. But where a soft and pliable rope is required, as the twist in the strands must be proportionally reduced, the strands will be liable to be thrown out of place and into kinks by careless usage. To obviate this ropes are sometimes made by braiding which, though it prevents the strands from being thrown out of place, is still more objectionable. As the strands in this case run around spirally in contrary directions a slight twisting of the rope either way will throw all the strain upon one half of their number. And where fiat bands are required such as saddle bands, reins Sac. the usual method is to make them by weaving like cloth in which case the crossing threads or Vv.lling only add weight to the fabric without aan. inmmnmasinoitslstrength, while the .iaking this class of goods by braiding as in braic ing ropes. i
The present invention by which all tl hereinbefore mentioned evils are avoide consists in combining the strands of an fibrous material by an interlocking twist i which the strands all take the same spira form that they would have in a twisted rop of ordinary manufacture, and yet hold eac other in place more efectually than'can t done by braiding. This new interlockin twist is formed by successively passing ever strand either over or under two others s that each of the two so entwined shall in il turn entwine two others.
The manner of forming a rope by my ne interlocking twist is clearly shown by co ored strands in the drawing in Fig. l for ir stance in which each blue strand passe around one yellow and one red, each re strand around one blue and one yellow an each yellow strand around one red and on blue. Each and every strand interlockin with two others. Fig. 2 shows the same I terlocking twist in the manufacture of wet bing for flat bands &c. each strand passin around two others viz one red strand passin around two blue ones, and one blue stran around one yellow and one red, the whol forming an interlocking twist in which eac and every strand is entwined with two other: In this my new form of twist it will be see that the strands all take the same spira form that they would have in twisted rop of ordinary manufact-ure, and as they hol each other much more rigidly and securel; in place and maintain the same spiral forn however slight may be the twist in eacl" there can be no unnecessary strain upon th fibers of which they are composed, while un der all circumstances, each strand will bca an equal amount -of strain with all other and the rope or fabric thus formed will b free from all liability to kink.
In the foregoing description nine is repre sented as the number of strands to form rope, but it is obvious that any other numbe which is the multiple of three may be used siX, nine or twelve strands forming a soli rope without any heart -piece, while an; greater number increased in the same ratii will form a hollow cylinder which will an swer for engine hose stout belting &c., and i any one of the strands is left out a flat ban( of a single thickness will be formed.
Having` thus described my improvements I shall state my claim as follows- What I Claim as my invention and desire have secured to me by Letters Patentis My improvement in the manufacture of rdage, webbing or other similar fabrics lich consists in laying up or so combining e strands as to form an interlocking twist in which each and every strand passes around and interloeks with two others as set 10 forth, and thereby brings the strain equally upon each strand.
