BRAIDED FABRIC AND PROCESS OF MAKING IT.

Qriginal application filed. August 6, 1906, Serial No. 329301.

a Specification of Reissued Letters Patent. Reissued May 27', 1913;

Divided and application filed May 28, 1907,

To all whomit may concern:

It, of whichthe following is a specification.

This invention provides for making a braided fabric of two or more distinct parallel webs, layers or plies interlocked or inter Woven by strands braided into andcrossing between the layers. Between the layers may be introduced longitudinal strands of textile material, rubber or wire. The fabric may be made fiat for useas fabric or. rubber belting; or it may be adapted for other uses.

. opposite carriers are causedto pass across at inter- The process of making such braided fabric consists in simultaneously braiding the two (or three, four, or more) parallel layers or plies by means of two (or more) series .of bobbins, those of each series traveling in directions; and simultaneously locking or tying together such two (or more) braided webs 'by interlacing strands intro duced by means of a supplemental series of bobbins crossing back and forth between the paths of the bobbins braiding the parallel layers. longitudinal strands are-introduced between those forming the parallel braided webs, and so that the interlacing strands cross back and forth between these longitudinal strands.

The apparatus for performingthis braidingprocess comprises two ormo're adjacent series of tracks or races traversed by the carriers of the bobbins of the first and sec ond series, and by the carriers for said supplemental series of bobbins. which latter vals from one pair of tracks or races to the other, suitable switches being provided to direct their crossing-over movements, and the carrier-propellmg mechanism belng pro- .port-ioned and adapted to receive this sup plemental set of carriers and impart to then. their proper motions crossing back and forth between the two series or pairs of races. For introducing the longitudinal strands, tubes are provided projecting between the webs emanating from gthe bobbins of the Atthe same time the intermediate first and second series and directed toward the braided multiple fabric.

Figure 1 of the accompanying drawings is a partly dissected side elevation showing a "braided hose in course of being formed. Fig. 2'is a transverse section of the completed hose. Fig. 3 is a transverse, section showing more in detail'the respective layers or webs of the braided fabric partly dissected, apart. -Fig. 3 is a diagram in the nature of a longitudinal section of the fabric, but showing only two strands of each web. Fig. 4 is a vertical diametral section of the elemental parts of the braiding machine.

Fig. 5 is a plan thereof, the bobbins beingremoved. Fig. 6 is a plan on a larger scale of a portion of the machine shown in Fig. 5. Fig. 7 shows one form of the longitudinal strands. Fig. 8 is a transverse section of the hose without longitudinal strands.

In Figs. 1, 3 and 4, A is the braided fab- .ric, and a the core on which it is or may be formed, For a hose this core maybe the lining tube of fine india-rubber, suitably supported Or the core .may be omitted. Around this is the inner braided layer or web 6, and inclosing this is the outer braided layer or web 0. Th'ese'two or more webs are tiedtogether by interlacing strands (Z, whichwhen drawn into place pass out and in in zigzag or star form, as shown in, Fig. 2. It is preferable to introduce between the inner and outer braided layers b'c longitudinal strands e e. These inaybe of textile yarnor metal wires useful for resisting longitudinal strains or they may be rubber strips in order to introduce a web or layer cit rub ber betweeng'th'e inner and outer braided layers; or preferably they are, as shown in Fig. 7, textile yarn's' f IIIClOSGCl ina rubber strip 9', thereby serving both purposes.

. Fig. 4) mounted .on carriers D nary braiding machine. Th carriers movein zigzag tracks or races formed in the upper race plate F supported on a lower plate G as usual. There are two'pairs of tracks or races, an inner one H and an outer one J. Each consists of two sinuous slots crossing each other at intervals as usual. The inner race H-is traversed by the inner bobbin car riers B, whose bobbins B lay thestrands b forming the inner braided web 6. The outer race J is traversed by the outer carriers C, whose bobbins G lay the strands c forming the outer braided web 0. The respective races are distinct except that at intervals cross-overs are provided controlled by switches K K (Fig. 6). The interlacing strands (Z are carried by a supplemental series of bobbins D (one of which is shown in which traverse the inner and outer races H and J alternately, crossing over from one to theother at the switches K, so that they follow the path of the dotted line 00 in Fig. 6. For

driving these carriers, push-wheels L L (Fig. 4) similar to those ordinarily used in braiding machines are provided, turning between the plates F G and having radially slotted horns or forks for engaging the toes P of thecarriers. They differ frorn'those heretofore used in having six horns or slots instead of four. The guides E for the 10ngitudinal strands are mounted each on a tubular post E (Fig. 4), the strands 6 passing up from any suitable reel through this tubular post and into the inclined tubular guide E. The uniting strands (Z, instead of progressing in only one helical direction (as shown in Fig. 1 being laid by bobbins following parallel sinuous paths (as shown,

for example. by the dotted line so in 6) are best made to progressin both hellcal d1- 7 rections, so that they cross and re-cross (as shown inFig. 3), whereby they are not only intermeshed with the strands forming the inner and outer webs b and 0, but they are interbraided. so as to form a braided'wel) distinct from the outer and inner webs.

*In making hose, the usual external coating of rubber 72- may be applied upon the outside of the braided web 0 after which the entire hose will be subjected 'to the usual vulcanizingprocess. During the vulcanizing process. the strips 7 g of rubber unite 4 i 1 into one integral layer or tube of rubber oetween the braided layers 7) and. 0. By introducing the rubber in this manner, any desired quality or composition may be used, so that this intervening tubular layer may be of as fine quality and as imperiious-as the inner tube or lining rubber thus gives the required friction and adhesion, instead of being a mere filling composition.

This improved hose has the distinctive ad vantage that its-lnner and outer webs are so This interposed tiedlftbgether orinterlaced as to effectually avoid theirjseparation, an advantage which is especially noticeable when the hose becomes old. The hose has greatstrength and durability. The braided webs render the hose very supple and elastic, whileaft'ording as great strength '21s a multiple-ply woven hose.

The process and product may be greatly varied as desired. Thus the braided layers may be more than two; the introduction of longitudinal strands e 6 may be omitted (as shown in Fig. 8) or these strands instead of being of rubber may be of yarns or wires. The invention may be used for making multiple-ply hose or fabrics of yaryi ng.

thicknesses Thus for a two-ply fabric two braided layers may be used without the intervening longitudinal strands; for a threeply fabric two braided webs and any intervening layer of longitudinal strands is used;

and for thicker fabrics, any combination of the respective layers may be resorted to; as for example, a five-ply fabric may be made by using three concentric series of bobbins so as to form three braided webs with two intervening layers of longitudinal strands. This applicationis a division of my application No. 329,i0l,'filed August 6,1906, to which reference may be made for a more complete disclosure of the braiding machine. I claim as my invention 1.
