This invention relates to a portable, elongated, cylindrical spindle adapted tof yieldingly engage the straight end edge of an elongated strip of textile fabric or similar thin flexible material and byrotation to draw said fabric from a source of supply and wind it into a roll around it and to act as a support for the roll during transportation to the place of use and in unwinding. It is particularly adapted for use as the drawing roll for cord tire fabric. Heretofore in winding fabric and particularly, cord tire fabric, embodying as it does comparatively few and comparatively weak transverse strands,'it has been found difficult to satisfactorily attach the end ofthe fabric to the roll for winding and to satisfactorily detach the end when the roll is un-` place the end of the fabric on the roll and drive tacksthrough it into the roll at intervals longitudinally'of the roll but this has many objectionable features. It requires great care, close attention and consumes considerable time inall cases to accomplishV an engagement with the edge in correct' alignment on the roll and with the fabric smooth and without wrinkles longitudinally of the roll and it requires'experience to do it satisfactorilyeven then. Detaching the fiXedly connected end from the roll when the fabric is unwound in use is also troublesome.y The tendency of the spaced tacks to unevenly stretch the fabric at the end is also objectionable. My present invention is intended and adapted to avoid these defects in construction and resulting troubles in operation and to make it easy to attach the end edge of the fabric to the spindle in properly aligned position'and without wrinkles transversely and to hold said edge firmly at all points throughout its length and to permit it to be automatically disengaged from the spindle when it is reached in unwinding the fabric for use. The invention furthermore has the advantages Of greatV simplicity of construction, low

. cost of manufacture, lightness and a surface including the clampingpart which will prevent displacement of the fabric by slipping. In the specific embodiment of the invention shown Vfor purposes of illustration, itV conthe outer diameter of the tube on which it ts. The Outer split tube closely fits the inner tube and its resiliency `causes it to yieldingly and uniformly press the fabric under it against the inner tube and this .pressure is increased if the inner diameterof the outer tube is made somewhat less than the outer diameter of the'inner tube.

The invention and its novel features will be more fully understood from the following description and claims taken with-the accompanying drawings.

` AInthe drawings:

Referring first to Fig. 3, which shows an embodiment of thein'vention only and' thus illustrates it mosty clearly, 10 represents the inner tube of the spindle and 11 the outer split tube and it will be noted that the parallel edges 12 and 13 of thesplit tube are spaced apart leaving an exposedsurface of the inner tube between them on which the end-edgeof the fabric may be placed and adjusted to proper alignment beforeV being inserted under the edge of the split tube for clamping engagement preparatory to winding.

edge 13, for instance, it is necessary, of course, that it shall be moved radially outward from the surface of tube 10 and held in its outer position during the movement of the end edge `of the Vfabric into properly adjusted position beneath it and although this may be easily done manually by one person While another adjusts the fabric or With a little eX 'perience it can be successfully done lby one -person alone, it is preferred to 'insert a small nf'edge circular in cross section at each end of the spindle 4between tlieedge ,portion of the split tube and the outer surface ofthe 'inner tube at a sufficient distance from the-edge to permit the end edge of the fabric to eX- tcndunder said edgetlre desired .distance for clamping engagement. This last arrangement makes it possible fora single person to easily-quickly and accurately attach'the end edge .of the Afabric tothe spindle for Winding. The straightcdge ofthe split tube serves as-a closely adjacent guide for the longitudinal alignment of theyend edgeof the fabric on the spindle `and since one Wedge will be removed before the other the operator may remove any Wrinkles then formed by holding the fabric in extended position with one hand While he removes the other Wedge Vwith his other hand.

.As will be seen by reference to Fig. 2, the fabric extends, from its end position le under the edge portion 13 of thesplittube 11, in `the saine direction around the exposed surface of tube 10 `over .edge 12 and thus in starting the Winding after the `end edge Vis clamped any resistance of the fabric tothe necessary longitudinal movement in Winding will 4be in azdirec-tion which will tend to, in a sense, pull the end edge of the fabric in a direct line out of the clamp. The uniform radial pressure on both sides of the clamped end of the fabric and a slight roughness vof the tubes in contact with it will however cause sufficient Yfrictional resistance uniformly distributed throughout the Width of the fabric to prevent any possible slipping or disarrange* Each layer of the fabric after the first vby its tension furthermore increases the clamping pressure. This arrangement furthermore has a very valuable function and advantage in unwinding the fabric for use since When the end is reached, the tension on the fabric will be in the right direction to most easily and With the least possible frictional resistance draw it from its position below tlie clamping edge 13 Without any injury to even the clamped end of the It Will be noted that in this operation the tension of the fabric tends to liftthe edge 18A from the surface ofthe tube thus aiding in the release. I i f The outer split tube shown in Figs. 1 and 2 isl ofVv greater 4thickness than that shown in Figi. 8 and has a longitudinallyextending depression la 'en its inner 'snif-aes midway between its parallel edges formed by scoring Which the form shown in Fig. 3 does not have. The reason for this is that if the semicylindrical tube is sufficiently thin it may be opened to the desired extent by a spring action in assembling and in use Without danger of breaking or splitting but it is sometimes desired to use tubes of greater thickness for purposes of strength and rigidity and the scoring makes this possible With- 'y j.

out danger of breaking during the necessary Opening.

It will of course be understood that the length ofthe tubular spindle varies with the Width of the fabric to be Wound on and car- 2O with its outer, rather sharp, edge 19 nor-W mally resting against one longitudinal edge of the slot 17 and terminating at for very slightly 'beyond the cylindrical outer surface of said bar. This pivoted strip serves as automatic means for so engaging the inner .i

surface of the inner tube 10 of the spindle as to cause it to rotate With the bar 16 when thatv bar is turned in one direction. When the spindle is in place on the bar 16'and the end 14 of the fabric is clamped to the spindleA and the outer portion 19 of tlie metal strip 18 i i rests against the edge 21,'of 'slot 17 with its rather sharp edge engaging, under slight pressure, the inner surface of tube 10 a rotary movement of the bar 16 in the direction,

indicated by the arrow in Fig, 2 to Wind the fabric Will tend to move the spindle with it Vand although the tension of the fabric resisting it Will tend to cause slight rotary slipping of the 'spindle Von' the bar, the contact of the inner surface of tube 10 with the 'ii-1'" edge 19 Will quicklyturn strip 18 on its pivot sufiiciently to make it so firmly engage the inner surface of tube 10 as to prevent any slipping. VV'hen the Windingrof a roll is finished 4 the rotary connection between the bar and spindle may be released by a slight reverse relative 'rotary movement.

The metal Winding bar 16 is solid except for the longitudinal groove 17 which is prefi erably V-sh-aped in section as shown in Fig. 2.

Although as above stated, the gripping action ofthe tubes on the fabric will ordinarily be sufficient to prevent Vthe fabric from being Withdrawninstarting the operation of Wind ,f

ing or during Winding Where the end edge of l the fabric extends under the edge of the outer tube for only ashort distance, it will be understood that the end edge of the fabric may extend under the edge of the outer tube and around the inner `tube as far as may be desired. For instance it may extend entirely around the inner tube to the opposite edge of the outer tube, as shown in Fig. 4. In this instance the end edge of the fabric is, of course, first placed on the inner tube in longitudinal position and is wound around that tube one turn and then the edges of the outer split tube are separated and the two tubes are then brought together longitudinally. This arrangement increases the gripping action both because of the increased contact surface and because of the increased diameter of the inner tube due to its winding of yarn.

Under some circumstances and particularly where it is desired that the end edge of the fabric extend only a short distance under the edge of the outer tube it is advisable to secure one edge portion of theouter 'split tube to the outer surface of the inner tube by paste or other adhesive material, 22, as shown in Fig. 2, in order to avoid any possibility that 'the outer split tube will turn on the vinner tube.

As heretofore stated, when the roll of fabric on the spindle has been transported to the place of use and is being unwound, it is not necessary to stop the unwinding movement to release the end of the fabric from the spindle since it will be automatically released by the tension of the fabric when it is reached and the pull is direct. A very useful and valuable feature of the present invention is that neither the fabric nor the spindle is injured in the least, during the winding or unwinding and that the spindle may be used many times. v

Although a specific embodiment of the invention has been' shown for purposes of illustration, it will be understood that it `is notV limited to details beyond those specified in the claims.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:

l. A portable spindle for clamping and winding textile fabric comprising in Vcoinbination, a cylindrical pasteboard tube, a split pasteboard tube closely and yieldingly fitting under tension and largely surrounding said tube substantially throughout its length, having spaced parallel longitudinal edges, the inner side of the split tube being of a hollow cylindrical tube of fibrous material adapted to be placed concentrically on said bar and to turn therewith, said tube having an unbroken outer cylindrical surface, Y and an elongated longitudinally split cylindrical tube of brous material fitting over said hollow tube and gripping the same by spring action, one edge of said split tube being adapted to be raised to receive thereunder one end of a web of fabric to be wound on said tubes, and the opposite edge of said tube being permanently attached by adhesive to the said-hollow cylindrical tube.

3. The combination with a winding bar of a hollow cylindrical tube adapted to be placed concentrically on said bar and to turn therewith, said tube having an unbroken outer cylindrical surface, and an elongated longitudinally split cylindrical tube fitting over said hollow tube and gripping the same by spring action, one edge of said split tube being adapted to be raised to receive thereunder one end of a web of fabric to be wound on said tubes, said split tube being scored longitudinally at a distance from its longitudinal edges to facilitate raising one of said edges from the hollow cylindrical tube.

In testimony whereof I hereunto aiix my signature.
