At the extremities of the barrel 5 l form projecting` tabs or lugs 12which are inserted through slits 14@ in the end-heads 6 and 7, see Fig. 3, and headed over as shown in Fig. 1 to fasten the heads securely in place against the ends of the barrel. The heads 7 carrying the brake-rims S are provided with hubs 15 which are iormed with reduced portions 16 riveted through holes 17 arranged axially thereof. Projecting outwardly from the hubs 15 are reduced gudgeons 18 which serveas the outer journals for the connected spools and are adapted to turn in the bearings 19 on the end-standards 20 of the carrier-rame (not shown). Between the two end-standards 20 on the frame are a number of similar standards 21 provided with capped bof-es or bearings 22 for supporting the inner gudgeons or journals ot the end spools 2 and 4 and the coaxial journals of the intermediate spool 3. While I have shown only one of the intermediate spools 3 in Fig 1 it is to be understood that a greater number of these may be used when required. The standards 21 have larger bearings than those of the end-standards 2O and their caps 23 are held thereon by the usual means (not shown) to adapt them to be removed to permit the spools to be readily placed in and withdrawn from the bearings.

My improved type of gudgeon-coupling or journal 25 'for these intermediate bearings is constructed from sheet-metal rolled into a ring, or it may consist of a short section cut from tubing. Fig. 5 illustrates one form of the gudgeons 26 and 27 for two abutting spools, each of which is constructed as a ring with projecting lugs 28 adapted to be insert-ed through slits 29 in the spool head 6, see Fig. 3, and headed over as shown in F ig. 1. ln this manner the gudgeons 26 ant- 27 are securely fastened to the heads 6 without the use of pins, screws, nuts, or other machined parts.

rlhe two abutting gudgeons 26 and 27 have their cooperating ends formed to provide an interengaging male-and-emale clutch or coupling, as shown in Fig. 5. @ne of the gudgeons 26 is cut away its end to provide four equidistant slots 30 adapted to receive a pair of projecting lugs or prongs 3l on the gudgeon 27. rihe gudgeon 27 might be constructed oi identical i'orm with that or the gudgeon 26, but preferably I employ only two engaging-lugs on one of the gudgeons so that the connected spools may be individually applied to or lifted out of the hearings and their cooperating' clutchingelements engaged or disengaged without displacing the spools endwise of their bearings.

Fig. 6 illustratesanother form of gudgeons or clutching-elements 33 and 34 adapted to he employed in place of those lirst described. In this embodiment of the invention the tubular gudgeon is slitted at 35 around onehalf of its circumference and the Vstrip of metal thus cut away is bent across thel end of the tube to term a diam'etrical rib or heyV 36. The free end of the rib 36 may be brazed at the oint 37 when it meets the edge of the longitudinal cut in the tube, and both gut geons 33 and 34 are of the same form, the drawing illustrating the parts in reverse positions in Fig. 6. llihen the two gudgeons are arranged in this manner at the abutting ends ot adjacent alining spools their ribs 36 will engage `one against the other to effect the coupling betweeen the spools.

in Fig. 7 the gudgeons 38 and 39 are shown as constructed in the form oi cups struck up from flat blanks. @neA of the gudgeons 38 has a diametrically-extending slot e0 cut through its flat end-face, whi e the other cooperating element 39 is formed with a corresponding diametrical rib or lrey el adapted to engage the slot. F ig. 2 illustrates the manner in which the two gudgeons 38 and 39 intcrengage with a spline and key connection to couple the adjacent alined spools to rotate together.

lTig. 2. also illustrates a modified form of construction for the barrel ot the spool. ln this embodiment of the invention the barrel l5 may consist o a wooden cylinder having its ends inserted into cylindrical flanges or sockets 46 fastened to the heads 6 by means ci the riveted lugs 17. Y

in use my improved spool units are arranged in axial alinement with 'their gudgeons j ournaled in the bearings of the standards 2O and 21 which are mounted on the carrier-'frame of the loom. By removing the caps Jfrom the bearings on the standards the spools may be applied individually to position therein, and as their journals seat in the bearings the ends oi the gudgeons will interengage to clutch or couple the several units together so that they will rotate as one under the control of the braking' means acting against the outer heads of the end spools.

It will be observed from the above description that my invention provides a. relatively light spool of simplified construction which is economical to manufacture and strong and durable. in use. The improved form of coupling-element or gudgeon for the end-journals of the spool provides for connecting the spool units at their abutting ends with a positive clutching action while eliminating the use of axial spindles, pintles, or other machined parts requiring screwthreads for holding them in place. The gudgeons are securely attached directly to the end-heads oic the spool by means of the lugs Jr'ormed integral therewith and their cooperating clutch-faces are designed to previde `for economical methods of manufacture with a minimum of machining operations.

The improved form of the spool barrel,

lcd

comprising integral holdingor seizingmeans for the ends of the yarns Wound thereon, also maires for greater simplicity in the structure of the spool While still further economizing in the cost of manufacture.

Various other niodiications besides those herein shown may be made in the form and structure of the parts of the improved spool Without departing from the spirit or scope of the invention; therefore, Without limiting myself to the exact embodiment disciosed, l claim:

l. i tutt-yarn spool for the carrier- 'f'raines or' looins comprising a cylindrical barrel having end-heads, and hollow cylindrical gudgeons' arranged coaxially of the heads and projecting outwardly therefrom with integr-ai clutch-elements at their ends adapted for interlocking engagement one with another when the spools are placed endor-end in series.

2. tutt-yarn spool for the purpose specified comprising a cylindrical barrel, sheetnietal heads secured tothe ends of the barrel, and tubular sheet-metal gudgeons projectingl axially from the heads and formed with ciutcli faces at their ends adapted for interlocking engagement one with another when the spools are placed end-for-end in series.

A tutt-yarn spool for the purpose speciiied constructed with atubular barrel having integral projecting lugs at its ends, sheet- -inetal end-heads having openings receiving the lugs on the barrel which are riveted therethrough, and tubular sheet-metal gudgeons having integral end'lugs which are also riveted through openings in the endheads, the outer ends or the gudgeons being formed with integral clutch-elements adapted for interlocking engagement one with another when the spools are arranged in series in axialalinement.

el. A tut-yarn spool for the purpose specified comprising a barrel with sheet-metal heads at the ends thereof, and tubular gudgeons provided with end-lugs riveted through openings in the heads to fasten them in position coaXially thereof, t-he opposite ends or the gudgeons being cut away in castellated form to provide cooperating clutching-faces adapted Jfor interlocking engagement when a plurality of spools are placed end-for-end in axial alinement with the gudgeons seated in their bearings.

5. A tutt-yarn spool for the purpose specified comprising a cylindrical barrel, heads at the ends of the barrel, and gudgeons projecting axially from the heads, said .bar-

`rolled into cylindrical form with its edges meeting in a seam and crimped to project radially outward to provide a longitudinally-extending exterior rib, the projecting portion of the rib being lrnurled or roughened on its surface to adapt it to grip the ends of the yarns Wound onto the barrel.

7. A yarn spool for a tube frame comprising a yarn-carrying barrel and end heads, each head beingprovided with a concentrically arranged number of spaced prongs projecting axially from the spool and adapted to form journal for rotatably supporting the spool and capable of interlocking with a similar journal of an adjacent spool to transmit rotation, substantially as described 8. A yarn spool for tube trames embracing a longitudinal barrel for carrying the yarn transverse heads, a plurality of spaced 'prongs located around the central axis or the spool and projecting endwise beyond the heads to form intermatching engagement With similar prongs on an adjacent spool to produce equal rotation of two adjacent spools, substantially as described.
