Be it known that l, WILHELM REIN13Rs,enl

gineer, a subject of the German Republic, residing at Munich-Gladbach, Germany, Am 5 Bahnhof Speick, have 'invented certain new and useful Improvements in Bobbin Holders, of whichy the following is a specification.

My invention relates to device for unwinding cross bobbins which are connectedwith one another and are unwound successively. It is known in warp and'spooling machines to connect spinning or twinning cops or the like and to unwind them successively. But the cops are each attached on independent spindles. If this known unwinding device were used for successively unwinding cross bobbins connected with each other, the bobbin stands in warp machines would, owing to the relatively great diameter of cross bobbins, become so large as to be impracticable for considerations of space. Therefore it wasfheretofore necessary to use only one cross bobbin for each single thread so that, after the several bobbins have been unwound up to a certain remainder, fresh bobbins must be attached which obviously causes great loss of time. Further disadvantages of this system are that the remainders must either be rewound or wound over to avoid loss of yarn for which operatives are required which is not economical.

One object of my invention is to remove these drawbacks which is effected by using a special bobbin holder. In this holder, a plurality of cross bobbins connected with their thread ends having independent sleeves are c'o-axially arranged on a separate collecting sleeve or spindle. A special spooling machine has been constructed some time ago which serves for directly spooling several sets of cross bobbins co-axially behind one another on a single sleeve which were then unwound successlvely. Here, however, the bobbins are not single bobbins connectedby threads which can be made on any normal cross bobbin machine but bobbins consisting of a single thread not tied together which, however, cannot be used in practice because "the bobbin machines which would be required would be fa'r too large and complicated. Besides, weavers would be unable to buy cross bobbins, crude or dyed ones, from an spinning or dyeing factory.

n the drawings, I have illustrated several constructional embodiments of my invention.

Fig. 1 illustrates a bobbin arrangement comprising two cross bobbins behind one another, v

Fig. 2 a bobbin arran ement comprising three cross bobbins behind one another,

Flg. 3 is a longitudinal section of two sinle bobbin sleeves with their common bob- 1n holder, arranged behind one another.I

rllhe cross bobbins 2 formed on the sleeves l are arranged co-axially behind one another 1n sets of two, three 'or more on a common bobbin sleeve 3, see Fig. 3. This sleeve at its front end has a ring et against which is abutting the rst cross bobbin. The rear end of the sleeve is threaded at 5 and provided with a nut 6 so that the bobbins can be h eld tightlyagainst one another and against ring 4 so that a rigid unit of bobbins is provided. The sleeve 3 is fixed 'on an'arbour 7 with such play that it can be readily put on and removed and a breakage can readily be detected by turning the bobbins about their axis. The arbor 7 is xed in a frame 8 but may also be adjustable in such frame. llnstead of sleeve 3, a solid spindle may be provided which is rotatably carried or held at one end in a corresponding holder of the frame, which is within the scope of my invention. The end 9 of each thread on oney bobbin is tied together with the beginning l0 of the thread of the succeeding bobbin so that all the bobbins will be unwound successively so that at least the bobbins at the front will be unwound completely and only the last bobbin will have a` remainder of thread. This remainder may now, as usually, be rewound or wound over or the last bobbin of each set may be used as the beginning bobbins when forming new sets of bobbins behindwhich the full bobbins are placed so as to unwind the bobbin completely without rewinding or winding over. Consequently a larger quantity of threadmay be mounted upon the warping creel with the.

tongs 12, respectively, should be perfectly lpolished in order to reduce to minimum the friction which the thread must overcome in moving past them.

The bobbin sleeve 1 has a grave 13 near to its greatest diameter where the thread mass is inserted which groove receives the ring of thread supply for tying each bobbin to the succeeding one.

As the cross bobbins to be tied together are attached to a common holder with their several sleeves which is adapted to be detached from the bobbin frame, the bobbins may be tied together and the sets of bobbins combined away from the frame. Notwithstanding the frreat lengths of the b'obbin sets, the present delay owing to attaching the sets will not become longer andl the attaching after the unwinding of 'every single bobbin can be dispensed with. Y

Notwithstanding the increased eiciency which is imparted, for instance, to a warp machine by my novel arrangement of bobbins, the dimensions of the machine are not increased in any way as it is neither longernor higher than a machine of the old construction. 'n the direction ofthe axis of the -tied away from the frame.

bob-bins, there had to be sufficient space for exchanging the bobbins which space is suilicient'for the sets of bobbins according to my invention, the more so, as the bobbins are Besides, any single cross bobbin of the normal known and generally used spooling machines may be used.

Claim:

A bobbin holder for warping creels comprising a sleeve, a flange formed on one end of said sleeve, the other end of said sleeve being threaded, a thumb nut enga ing said threads, a plurality of cross-woun bobbins with cross wound cheeses arranged on said sleeve, said bobbins being retained on said sleeve between said flange and nut whereby said sleeve and bobbins may be placed loosely on a warping creel spindle.
