{I The present invention relates to looms or -machines for weaving tubular fabric and more especially, to safety devices for the same.

'Among the objects of theinvention is to provide means to reduce the supervision regquired when such machines are operating by I Mounted on .members Fig. 5 is a view as from'line 5-5 of Fig. 4; Fig.6 is a sectional view t-akenon line (i-60f Fig. 2.v 1 Y Fig. 7 shows a detail of the machine.

As indicated in the drawings, the, loom .is constructed with a circular frame 10 comprising a base portion 11 and cylindrically p arranged-uprights 12, adapted to support the moving parts. i p I base 11, is a shaft 13 carried in suit-able bearings, not shown, which shaft has keyed thereto a gear 14 which may form part of a sleeve 15 which carries a pulley 16. Also carried on shaft is an idler pulley 17.

Fixedly centrallyon the base 11 is avertical tube which serves as a fixed shaft about which rotates the frame member 21.

This member 21 is supported on the base 11 by a suitable-anti-frictionbearing 22 and includes an outwardly extending portion 23 having at its outer edge a downwardly extending cylindrical part 24 in whose outer surface is a-pairof slots 25 for purpose to be mentioned later. The-bottom edgeof portion 24 is provided with a ring gear 26 "which coacts with thegear 14 to drive the member 21.

described later.

- The upper end of the shaft 20 is open and member 50 and has at its lower end a smal Located above the part 23 of member 21 is a second outwardly extending frame port on 30 carrying on 1ts upper side a pair of small frames 31, each having bearings 32 for shafts 33. The shafts 33 have at one end a small wheel 34 and at the other end a sec- 4 0nd wheel 35. V

The'frame '31 and its associated p artsis shown in enlarged view in Fig. 3. This figure shows that one of the bearings 32 for shaft 33 consists of a bearing part 32a mounted as a plunger in the inner end of the frame and supported by a spring 325 so that the shaft 33 and the wheel 34 will be spring pressed upwardly.

Also carried on head member 40 which has on the under side of its periphery a track 41 for wheel 34 and against which the wheel 34 is spring pressed,

as is mentioned above.

This head member 40 furnishes support on the upper side of its periphery for the small wheels 42 which will .be more particularly may have fixed therein a hollow mandrel 43 serving as the outside form for the tubular roduct which passes down through the shaft 20 to a suitable receiver, and fixed above the upper end of the tube is a small frame 44 carried upon an arm 45 suitably supported .by the outside frame 12. This arm carries an inside mandrel 46, whose lower end extends down into the tube-20 and serves as the inside form for the tubular product.

This frame member 44 is provided at its lower edge with a track portion 47 which overlies the small wheels 42 hereinbefore mentioned. 4 V

Carried by the outer frame 12 is a fixed upright cylindrical member 50 having a plurality of vertical slots 51 through which slots extend the warp cords 52, each ofthese cords extending from a suitable reel, not shown, through an eye 53 on the side of the frame and through a second eye in a guide rod 54. From the rod 54, the cords extend each through an eye 53 in a heddle 55, which heddle passes through a suitable opening in the hollow shaft 20 is a i Within the member are two shuttle mem{' bers whichare moved around the center of the machine and supported-on thesmall 5 p Y p 7 Y end a handle 81 serving to permit manual wheels 42 near the center and large horizontally placed wheels 61 adapted to travelin a suitable groove 62 in member 50. Each one of these shuttle members '60 has atone end near the member 50a small wheel 63 which extends beyond the shuttle frame 64; so that it may c'oac't with the wheel 35,.which is carried by shaft 33, as shown in Fig.3. The

wheel 35 is so located with respect to wheel 63 that as the frame 31 is carried around the center of the machine, this wheel 35 pushes the shuttle around withit and as the'frame 31 carried around shaft20, the 'small'wheel 34 coac'ts with its track on the head member 40' so as'to rotate and inrrot'atingrevolves wheel 35.

As the member 23 is carried around by the gear 26 the heddles move up and down in their proper order and the shuttle passes un der each alternate warp cord 52 and over the intermediate cords'due to the changing of the position of the cords by the heddles. The wheel 35 rotating against Wheel 63 andmoving the shuttle in its circulartpathwill easily and without danger to the cord, roll it up between the two wheels, as the shuttle passes,

,this' being due to the fact that thefwhe'els 35 and 63 rotate in such directions that their peripheral surfaces adjac enttheir point of contact move upwardly as thewheels rotate.

which'contains the weft material and allows it to pulled, out to the weaving position at the mandrels 43 and 1d.

; As the weft material 71 is drawn from the reel, it passes over two pins an d"73fand behind an intermediate pin The'intermediate pin is in fixed position upon the shuttle 9 frame whilethetwo pins 72 and 73 are carried by an. arm pivoted art-76 on the frame, both pins being on the same side of the pivot. The arm is extended beyond the "pivot 7 6 and has at its other enda shoe member 77 which hassecured thereto a spring 78 secured at its other end to the frame 6 1 in such position as to move the arm to bring thepins .72, 7 3 and 7 ioutof alignment and pullthe shoe 77 to the dotted line position shown in Fig. 4. So long assuflicient tension is applied to the end 71a of the weft mate rial, that is, so long as the weaving operation is beingconducted satisfactorily with a continuous drawing of the'weft material from the reel70. the 'tension on this material will maintain the pins 72, 73 and 74 in substanmovement of the shaft and having at its inner end a short vertical shaft 82 secured to shaft by means of a suitable fitting 83. When the shoe 7 7 swings to the dotted line position of Fig. 4, it strikes the end of shaft 82, and thereby causes a partial rotation of shaft 80 m a counter-clockwise direction, assuming the observer to beat the right of Fi 2 and tgie shlligtles to be moving counter-c ockwise v 1g.

When the shaft 80 is moved as indicated the projection 85 carried thereby ismoved ried by or formed upon the upper end of a vertically arranged shaft 88. This shaft 88 has near its lower end a second horizontal arm 89 connected to a longitudinally movable rod 90, carrying a belt shiftingjfork 91, and slid-able in a suitable guide 92. A second guide and abutment 93 serves as a stop member for the fork and between this-and a suitable collar 94 is placed a spring '95 arranged to be under compression when the belt 96 is on pulley l6. 7 When, therefore, the weft material 71 ona shuttle breaks, the shoe 7 7 moves out and strikes shaft 82 releasing arm 87 and allowlng the belt to be shifted,-throi1gh the V v ex ansion ofs rin to the idl r ll 17. ,Each shuttle 60 'earriesthereo'na reel-7O p p b 7 e Pu ey herein set forth, but only by the scope of the claims which follow.

I claim: 1. Circular loom comprising a central "mandrel, shuttles adapted to be moved around said mandrel, supportingand driving Wheels on each shuttle, and means for moving said shuttles around said mandrel, said means comprising a driving member having mounted thereon radial shafts each carrying a wheel adapted to contact with the driving wheel of a shuttle and each likewise carrying a second wheel located radially inward of the Y first and a stationary track located above said second wheel and with which said second Wheel contacts, whereby to cause said shaft to rotate axially in a direction opposite to from behind a cooperating projection-8 6 car- 'ried by a'horizontally movablear'm 87 carnormal as the shafts rotate orbitally around the mandrel when said driving member is actuated, one of the supporting wheels of the shuttle resting on the upper surface of said track.

2. In a circular loom, the combination of a main frame having a central mandrel around which a shuttle may be revolved, a driving means, a stationary member, a friction wheel, a pushing wheel mounted on a shaft which is driven by said friction wheel, said friction wheel being mounted on a portion of the driving means and held in contact with the stationary member by a light spring.
