To (ZZZ whom it may concern.

Be it known that I, HILAIRE on GHARDON- NET, a citizen of the Republic of France, residing at 22 Place Malesherbes, Paris, France, have invented new and useful Improvements in Apparatus for Treating Artificial-Silk and like Threads, of which the following is a specification.

My invention relates to apparatus for treating threadsof collodion or like filaments with reagents or other suitable liquids, in order to denitrate, bleach, dye, or otherwise affect such threads under the best conditions of uniformity and regularity. The particular object of my invention is a bobbin so constructed as to carry the mass of thread intended to be subjected to the action of the reagents in a manner that will allow of the reagents circulating through the mass under the action of centrifugal force when the bobbins are rotated in compartments containing the liquid reagents. The present application is a division of a copending application, Serial N 0. 40,272.

My invention consists in the construction, combination and arrangement of parts herein described and claimed, and illustrated in the accompanying drawings, in which similar reference characters illustrate corresponding parts in all figures, and in which Figure l is a longitudinal section through the axis of a bobbin the component parts of which are adjusted ready for winding on thread from the twisting machine;

Fig. 2 is across section taken through the middle of Fig. 1;

Fig. 3 is a front elevation showing a bobbin at the end of the winding operation and filled with thread; and,

Fig. 4 shows a bobbin in elevation after treatment mounted on a stationary vertical spindle of the table of the winding machine ready for the thread to be unwound.

Referring to the drawings, which illustrate a preferred embodiment of my inven-.

tion, the bobbin comprises a core or body A provided with a central longitudinal hole a. which has preferably two sets of radial rods, each set being arranged in a single transverse plane, and the rods terminating in points 6 7), of which one set I) are curved, and the other set I) are straight. These radial rods serve to hold the mass of twisted thleild on the bobbin during the treatment The radiating rods 1) have their points curved as shown in Fig. 2 to facilitate the subsequent removal of the thread, and are made of any suitable material which will remain unaffected by the reagent used for treating the thread, such as wood, ebonite, glass or enameled metal. These points are preferably sharp and have a smooth surface so that the thread will not catch upon them when it is being unwound, and the length of the rods is such that the curved points project slightly beyond the mass of thread when the bobbin is fully wound, the maximum diameter of the thread being indicated by the dotted line in Fig. 1 designated by the character (1.

The radial rods having the curved points 6 may be permanently fixed in the core A; this set of rods is placed at the end of the bobbin which will be the top during the unwinding operation. The set of rods having the straight points 6', and which are. located near that end of the bobbin which is at the bottom during the unwinding opera tion comprises individual rods inserted in holes in the core, and held there merely by friction, so that these can be removed when it is desired to unwind the thread from the bobbin.

Extending longitudinally of the core A and parallel thereto some distance from the core are a number of rods 7", made of any suitable material. These may be rigidly secured to the core A and are long enough to extend farther than the thread when the bobbin is fully wound (see Figs. 3 and 4). These rods may correspond in number to the number of rods in each radial set, and are preferably located immediately adjacent to theradial rods, as is indicated in Fig. 2.

Disks E are screwed or otherwise attached upon the axle B, and these disks have grooves 9 adapted to receive the ends of the core A. In addition, the disks E are provided with holes or depressions h which are adapted to receive longitudinal bars F which are made of wood or other suitable material adapted to form a cylindrical surface at a distance from the core A slightly greater than the distance irom the core A to the rods f so that the bobbin is adapted to be rotated by frictional contact with the drum D of the winding machine (see Fig. 8). This drum D is provided with grooves opposite the sets of radial rods so as to allow of the remaining surface of 'the drum D contacting with the surface of the bobbin on which the thread is to be wound.

The operation is as follows: When the bobbin has been assembled as described, it is taken to the winding machine, and the ends of the axle B placed in the bearings C of this machine. The frictional drum D is then in contact with the rods or bars li and rotation of the drum D thus causes the bobbin to revolve, and the thread is wound upon it.

Vv hen a bobbin has been completely filled" with thread, one or both of the disks E are taken off, and the longitudinal bars 1 are drawn out from the end, leaving the thread. supported upon the rods f, and the radial rods Z) 6', and leaving an open space inside i the threads between them and the core A.

in this condition the bobbin and thread wound thereon are subjected to the action of the reagent, and by reason of the way in which the thread is supported upon the bobbin, the reagent may be caused to flow from the interior of the bobbin to the exterior by the rotation of the bobbin.

When treatment has been completed, the bobbin is placed in a winding machine, and covered with a cap g, shown in dotted lines on Fig. d, the edge of which reaches approximately opposite the points 6 of the upper series of radial rods. The lower set of radial roos, those having the straight points Z), are drawn out of the core A, and the threads are thus supported by the upper ring of points 5. As these points 7) are curved in a backward circumferential direction, there is no tendency for the thread leaving the bobbin as it is drawn off above to catch upon the points.

Having now described my invention, 1

naaaeeo claim and desire to secure by lnited States Letters Patent:

1. A bobbin comprisi nal rods carried by said from the surface thereof, projecting: outward from the longitudinal rods.

2. A bobbin comprising a core, longitudinal rods carried by said core and spaced from the surface thereof and from one another, and longitudinal bars adapted to be removably disposed between said rods for contact with a driving; drum.

3. A bobbin comprising a core, longitudinal rods carried by said core and spaced from the surface thereof and from one another, and disks adapted to be remorably secured to said core, and longitudinal bars disposed between said rods and supported by said disks.

4;. A bobbin comprising a core nd a series of radial rods projecting therefrom, said rods having ends curved circumferentially in one direction.

5. A bobbin comprising a core and a series of removable radial rods adapted to support threads wound on the core against longitudinal movement.

6. A bobbin comprising a core, a series of radial rods removably disposed thereon, and a series of radial rods having circumferentially curved ends carried by said core.

" A bobbin comprising a core, longitua core, longitudicore and spaced and radial rods the core beyond 1. dinal rods carried by said core and spaced from the surface thereof and from one another, radial rods carried by said core and projecting beyond said longitudinal rods, and removable bars adapted to be placed between said longitudinal rods to form a frictional driving surface for Winding.

In testimony whereof I have signed my name to this specification.
