SPOOLS FOR TUFT-YARN CARRIERS.

Specification of Letters Patent.

Applicationflled June 18, 1910. Serial No. 567,577. v

atente July 15, 913.

My invention relates to spools, which may i be used on tuft yarn frames and carriers in wide looms for weaving tufted fabrlcs, and

' in which two or more spools are used in a 7 single row.

he object of my invention is to improve upon the construction of spools as ordinarily made, of the class referred to.

My invention consists in certain novel features of construction of my improvements as will be hereinafter fully described.

I have shown in the drawing spools of my improved construction, and their bearings', and friction mechanism, combined with a tuft yarn frame and carrier for wide looms, such asis ordinarily used in weaving moquette, or tufted fabrics.

Referring to the drawing ;-Figure l is a front view of a tuft yarn frameand car? rier with my improved spools combined therewith. Fig. 2 shows, on an enlarged the direction of arrow a, same figure. Fig..

4 is a section, on line 4, 4, Fig. 1, looking in the direction of arrow b, same figure. Fig. 5 shows the spool head detached. F g. 6 is anedge view of the head shown in Fig. 5, looking in the direction of arrow 0, same fi ure, and Fig, 7 is a plan view of the movable cap of the" bearing shown in Fig. 3, looking inthe direction of arrow 6, same fi j I irl the accompan ing drawing, 1 i a hollow metal tube with tweed center I, to which is secured the meta-l plate 2, which carries "the tubes 3, throughwhich the tuft yarns,- not shown, from the spools, not shown, ass.- Each an of the tube 1 has fasten' thereon the upwardly extending ends-of the arm's .4 are adapted to engage or enter links of the c'hain carrier, not

shown. spring catches 5 are secured at their lower ends by a screw 5 on the arm 4, and have a hooked shaped end 5" on their upper end, to cooperate withthe chain carrier which holds and carries the frame, as is customary in looms of the classreferred to. All of the above mentioned parts may be of the usual and wellknown construction.

I will now describe my improvements.

The spools 6,'in case-they are used'on a tuft yarn frame and carrier of the class referred to, ordinarily have a longitudinally extending square groove 6 therein, to receive a wire or rod, not shown, which attaches the ends of the tuft yarn, not shown, to the spool,-when the yarn is to be wound thereon. I have shown in the drawing three spools 6, which are attached together to extend in a single row, and act as one spool,

which extends across the width of the loom. The spool heads or ends, which are ordinarily made of wood and are liable to break,

are in my improved construction made of metal, preferably of ressed sheet metal, see Figs. 5 and 6. The 'eads or ends 7 have a center hOle.7 punched therethrough to rereceive the g'udgeon or journal .of the spool, to be hereinafter described. A square hole 7 is made in this instance at one side of the center, in line with the longitudinal groove 6' in the barrel 6, by cutting the metal in thr'e'e' places and bending inwardly the up 7" thus formed, said lip enters the outer end of the square groove 6, as shown at the right in Fig. 2. In addition to the integral 11p 7", there may be one or more, preferably three triangular shaped integral lips of projections 7 formed on the heads or ends 7, by cutting the metal. The prongs or projections 7"" are bent inwardly and forced into the ends of the barrel or beam 6, when the ends or heads 7 are pressed thereon, as shown in Fig. 2, and act, in addition to the lip 7' to prevent the heads or ends rrom turning on the barrelof the spool.

The gudgeon's or journals 8 of the spools haveiii this instance the shank portion 8, adapted'to extend through the central hole 7 in the-head or end 7 and into a central bore 6 in the wooden barrel 6, and the an- 8 presses against the metal head or end 7, as shown in Fig. 2 at the left, to secure the head or end 7 to the barrel of the spool 6. A pin 10 extends in this instance through a transverse hole in thee-spool 6 and in the shank 8', and acts to prevent the journal 8 turning in the spool 6.

The gudgeons or journals for the inner contiguous ends of thespools 6, have preferably the enlarged heads 11 and-12, in this instance one of the heads, as 11, is provided with a transverse fin or extension 11', adapted to enter a correspondingly shaped transverse recess in the head 12, making engaging portions, to cotiperate with each other, and form a coupling or connection between two contiguous spools, to cause two spools to rotate in unison. Instead of a fin or project-ion entering a groove, to form a coupling or connection, other forms of connections may be used. f

The gudgeons or journals on the inner ends of the spools 6, are secured thereto in the same manner as the gudgeons or. journals on the outer ends, as above described.

The bearings, intermediate the end bearings for the gudgeons or jpurnals 8 on the spools 6, are preferably so made that part of the bearing is readily movable, so that the spools may be readily disconnected from the bearings. In this instance the bearings consist of a stand 13 havin a foot 13' secured to the tube frame 1. he stand 13 has a curved part 13" thereon, formin r half of the bearing for the enlarged ends of the gildgeons or journals 11 and 12 on the spools 6. The part 13 has a side extension 13 thereon, with a screw-threaded hole therethrough. .The other half of the bearing consists of a movable cap 14, which is preferably made forked shaped at its lower end, and is hinged or pivotally secured on a stud l i to the stand 13. The cap 14: has the extension this instance a projection 14", which forms a handle or engaging part for the cap 14.

When it is desired to remove a spool 6, the screw- 15 is turned up, as shown by broken lines in Fig. 3, and the slotted end 14" of the cap 14, through the location of its pivot stud 14', will pass by the head of the screw 15, and the cap 14 will move upwardly and outwardly, as shown by broken lines in said Fig. 3, to leave a free passage for the removal of the enlarged ends 11 and 12 on the gudgeons or journals 8. j

The friction mechanism shown in the drawing for the spools 6, consists in this instance of a spring arm 16, see Figs. 1, and 4, which at its lower end is riveted to the arm' 4,. and extends inwardly, and has preferably made separate therefrom and attached to its upper end, a circular plate or disk 17, having a hole 17 therethrough, see Fig. 4, for the bearing 4, and the end of the journal 8 of the spool. ably upon its inner surface a yielding materla-l 18, see Fig. 1, which may be leather, or other suitable material, which is pressed against the outer heads or ends of the spools, and acts as a yielding friction surface for the spools. 4

The friction mechanism, shown in the drawings for the spools 6, and above described, forms thesubject matter of another application, and is not claimed herein.

It will be understood that the details of construction of my improvements may be varied if desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is Y LA spool, comprising a barrel with a longitudinal groove in its periphery, having sheet metal heads with a central hole therethrough for a gudgeon or journal, and said gudgeon or journa and also having a hole at one side of the center, with a li or ex-- tension at one side of said hole, w 'ch ex- The disk 17 has prefertends into the end of said longitudinal groove,

2. A spool, comprising a barrel, asheet metal head having means to prevent the same from turning on said barrel, a gudgeon at one end, having a portion to enter said barrel, and having an enlarged head on outer end with an engaging portion thereon, to cooperate with a corresponding engaging portion on the enlarged head or outer end on the gudgeon of a second spool, and said second spool, said engaging portions forming a coupling to cause two spools to rotate in unison, and the enlarged heads orouter ends ofthe dgeons forming the journal for two contiguous spools.
