My invention relates to multiple bobbin carriers for braiding machines, and more particularly to an improved mounting of the bobbins on the carrier, my main object being to increase the material capacity of such carrier without increasing its spread or diameter. Heretofore, in carriers having multiple bobbins, the latter have been invariably placed side by side, involving an enlargement of the racetrack circle of the machine for their accommodation; such enlargement beyond a certain size being uneconoinical and resulting in a limit to the capacity of each carrier eitherin the number ofbobbins employed or the material capacity of each bobbin, too small a supply in the several bobbins necessitating an uncommercially frequent stopping of the machine for replenishing.

l/Vith this main object in view my improvements comprise novel means of mounting the bobbins in superimposed relation or tiers, permitting the employment of an increased number, each having adequate supply ofmaterial, with little or no increase of the raceway circle, enabling me to manufacture, in a commercially successful and economical manner, a variety of braids not heretofore pos sible, and particularly those of heavy individual strands.

lVith this main object outlined, and with others that will appear as the description progresses, my invention comprises the structure hereinafter fully set forth in connection with the accompanying drawings, the novel features thereof being pointed out in the appended claims.

Fig. 1 is a front elevation of a multiple bobbin braiding carrier embodying my invention as applied to a particular type of carrier, parts being broken away or shown in section to more clearly disclose detail structure.

Figs. 2 and 8 are respectively corresponding side and plan views of the same. i

Fig. 4 shows a modification of my invention. v The carrier'indicated in the drawings is particularly adapted for use in the type of braiding machine more fully shown and described in the patent'of Robert Carl Rahm, No. 1,182,036 dated May 9, 1916,,but serves to illustrate my'invention in' a preferred and successfully operative embodiment;

Referring to the drawings, 5 represents gen- I erally the race-way engaging foot portion of the carrier and 6 the bobbin supporting standard thereon, the latter, as shown, comprising three spaced apart and inverted U-shaped members 6*, 6 and 6, and a uniting top cross bar member 7, provided with arow of thread guide eyelets 8, four being shown, one 'for, each of the four bobbins 9, 9 and 1 0, 10 herein employed.

- These bobbins, which are of the horizontal spool type preferred for the carrier indicated, are mounted on standard 6 in a novel and improved manner designed for theiroperating in a minimum of space required for their travel about the race-way course of the machine, which latter may be comparatively small for the number-of strands thus introduced. This novel mounting anes in placing- spools 9, 9 side by side in one. tier and superimposing spools 10, 10 in a second tier, preferably directly above the lower tier, such mounting utilizing four large spools while occupying only the space heretofore required by two, Two or more additional spools of equal size'might readily be added in a further superimposed tier or tiers without increasing the spread of the carrier or increase in the size of the race-way circle of the machine, thus greatly increasing the carrier capacity and the nature of the braid pro- 7 ducible commercially therewith: without any machine change. l I

In order that the bobbins thus mounted for economy of space may operate freelyand independently as required, each bobbin is mounted as shown on a standard supported spindle'll so as to' 'freely rotate thereon and each is provided" as shown with an independent tensioned brake control for the unwinding feed of its supply strand. The spindles 11 extend entirely across the standard 6, in two alined lengths,as shown, with ard so as to swing across said apertures as shown and prevent axial displacement of the spindles. These latches are maintained in apertureclosing position, as shown, by attached springs l5, the tension of which I preferably utilize also by attaching its opposite end to a brake shoe 16 to force said shoe into contact with the rim of its respective :sp'ool so to control the feed rotation of the latter on its spindle. These brake-shoes may be conveniently pivotally supported on upper and lower transverse shafts 17 and 18, as shown, carried by the standard 6, and each brake shoe provided with an operating arm'19,to the outer end of which is pivoted one end of a rod 20, projecting vertically therefrom'with its opposite end slidably supported in a bearing lug 21 on standard 6. Adj acent'each said lug on the respective rods, and preferably normally projecting therefrom in the same plane, are four fixed arms '22 projecting in the path of four tension weights 23, so that contact with any arm 'byits respectiveweight will lift its rod 20 -and through its operating arm 19 free said brake by turning it on its pivot.

The four weights 23, as shown, are vertically slidable in ,guide ways formed in the opposing walls ofthe rear legs of U-shaped members 6, 6 and 6, and by two additional uprights 24, 24 carried by the foot portion 5, and-each weight has afreely rotatable pulley 25 mounted on its top face by which it is vertically lifted inits respective guide way. A row of four idler ' top pulley wheels 26, 26, 26,26, are shown rotatably carried on a shaft 27 having bearings in theupper portion of said rear legs of inembers'6, 6 and 6, and also in the 'top ends of additional up right 24, 24, which shaft maintains the latter in fixed upright positions. Two other idler guide pulleys 28, 28, are shown carried by a shaft 29 mounted ininwardly projected extensions 30 from the front legs of members 6, 6", and 6. The strands of material from the two lower bobbins 9, 9,in the particular embodiment of the drawings, pass over the respective idler . guide pulleys 28, 28, to their respective top idler pulleys 2'6, 26, thence around their respective weight pulleys 25 and plates '14, insures proper tension only when out further showing or description.

The foregoing description clearly sets forth my invention as applied to the particular carrier shown and successfully employed in commercial. production; but my invention is equally applicable to other type of carriers to supply each with a multiple number of bobbins, eitherto increase their capacity for long uninterrupted runs as by unitingthe end strand of one bobbin to the beginning strand of the next, or to provide a plurality of strands to be interwoven, or for other novel effects as may be suggested or developed in practice. In Fig. 4 I have indicated a modification in which the foot portion 5 carries a standard 6 on which the superimposed spindles 11 are inclined angula'rly "to receive a vertical type bobbin; the essential common feature being the introduction of increased bobbin supply by superimposing the bobbins, instead of placing them side by side, so as to add additional supply without increased spread of the carrier or enlargement of the race way circle of the braiding machine.

In addition toflthe specific modification shown andabove referred to, other modifications within the spirit of my invention may be readily devised, and I do not desire to limit myself to the constructions herein set forth in detail, but what I claim is:

A bobbin carrier having a race-way-- engaging foot portion, a plurality of bobbinsupporting spindles mounted thereon in superimposed relation, with individual threadtens1on1ng and releasing means for each sp1n+ dle supported bobbin, and separate thread guide eyelets arranged in spaced relation to each othenand to their respective bobbins so as to maintain a fixed separated arrangement of the bobbin threads extending beyond said eyelets.

2. A bobbin carrier having a raceway- ,engaging foot portion, a plurality of bobbinsupporting spindles mounted thereon in tiers, with lndividual thread-tensioning and releaslng means for each spindle supported bobbin,
