MANUFACTURE OF BOBBINS, SPOOLS, OR THE LIKE.
Application filed March 9, 1927. Serial No. 173,993.
This invention relates to spools, bobbins and the like, more particularly to bobbins which are used in textile operations.
Heretofore bobbins have been manufactured with the flanges built onto the bobbin core in a plane strictly normal'to the axis of the core. As a result of this, the flanges are very easily bent out of the normal plane.
This distortion of the flanges interferes with the usual winding operations and makes it necessary to discard such distorted bobbins.
An object of this invention is to provide a bobbin whose flanges are constructed in a novel manner, giving the same increased 5 strength without substantially increasing the bulk or weight.
Another object of this invention is to pro vide a bobbin that is strong, inexpensive and of simple construction.
Another object of this invention is to provide a bobbin which can be re-used several times without in any way adversely affecting the winding or other textile operations.
Other objects and advantages will appear from the detailed description of the invention.
In the accompanying drawings illustrating this invention,
Fig. 1 is a perspective view of the improved bobbin;
Fig. 2 is a vertical section through the center of the bobbin.
Like reference numerals designate similar parts throughout the several views. In the drawings the bobbin is indicated by the reference numeral 10 and consists of flanges 11', 11 mounted on a core or barrel 12, upon which core the yarn is wound. Within the core 12 is a central core 13, which is crimped at its ends, as at 14, to rigidly fix the flanges 11 thereto. This central core 13 fits on the spindle for Winding urposes. In order to prevent the core 12 rom becoming disarranged or displaced the inner faces of the flanges 11, 11 are provided with annular depressions 15 into which the ends 16, 16 of the core 12 are fitted, as shown in Fig. 2.
The flanges 11, 11 in the present invention are formed with their circumferential portions bent outwardly as clearly indicated at 17, 17 in Fig. 2. This differs from the con ventional type of flange which consists of a plane surface at right angles to the core of the bobbin.
Thisconventional type of flange, either plain or ribbed, is very easily distorted in use. It is easily bent and tends to bend inwardly. When thus distorted the bobbin is rendered useless for winding since it interferes with the winding of the yarn for the full length of the traverse. This gives rise to soft edges or spots in the yarn body which prevents the yarn from being properly unwound from the bobbin.
The numeral 19 designates the line taken by the thread or yarn being wound onto the bobbin at the ends of the traverse. It will be understood that a bent flange prevents the yarn from being wound across the full width of the bobbin the yarn windings ending at the innermost point where the flange is bent. The formation of the soft spots is due to the fact that the thread or yarn is unable to be wound the full width of the core or barrel 12, because of the inward bend of the flange. This results in a space being left between the flange and the yarn bod Some of the windings of the yarn slip o from the yarn body into this space leaving voids in the yarn body and themselves becoming entangled.
The outwardly curved rims of the flanges employed by me results in a marked increase in the strength of the flange and add greatly to the resistance of the flanges toward. the distortion and bending, such as usually result from mill use, transit, etc. Also various advantages in the textile operations follow from the employment of this improved bobbin in the place of bobbins containing the conventional plain or ribbed flange.
The improved bobbin containing curved flanges is strengthened to such a degree that the same not only resists damage in transit but also in the mill and in various winding operations. This makes it possible for the bobbin to be reused a large number of times, because it retains its perfect shape.
Even'when the improved bobbin is sub-- jected to very severe and unusual strains so that even the strengthened. flange is bent inwardly, the bobbin is not rendered useless. This is so because the flange can be bent inwardly for some distance before it will pass beyond the plane normal to the bobbin axis at the junction of the bobbin core and the flange.
The flanges 11, 11 of the applicants inven tion can be made from pressed tin plate or sheet steel. The curvature necessary to give these flanges the added strength and durability desired can be obtained either by stamping out the flanges in this shape or by spinning the same into the desiret shape or contour from sheet metal. Because of the in creased strength resulting from the curvature of the flanges the latter can be made of lighter material than was possible heretofore and still be strong enough to withstand the rough usage that such objects ordinarily receive.
'The outer core 12 can be made of cardboard. fibre, wood or the like. The center core 13 can be made from either tin plate or steel. The former gives a sound and satisfactory bobbin but the steel center core gives a much more durable bobbin, one which can undergo con,- siderable use without the flanges becoming loosened or displaced.
Bobbins constructed in accordance with this invention, with and without yarn wound thereon were dropped from considerable distances and otherwise thrown around and abused. Even in the case of the bobbins containing as much as 7 to 8 oz. of yarn no appreciable damage was done to the bobbin or the flanges. In every case the yarn on these bobbins was unwound without any trouble or breaks in the yarn. In some instances where a bobbin with a tin plate core was used the dropping of a loaded bobbin resulted in the loosening, but not in any marked distortion, of the flange. It will thus be seen that the applicant has succeeded in producing a bobbin which will better resist the ordinary usage to which bobbins are subjected, although the same is lighter in weight than bobbins heretofore uset. I
Having described my invention, what I claim and desire to secure by Letters Patent is: 7
An improved bobbin for yarns comprising in combination a metallic core, a second core made of a fibrous n'i'aterial containing said metallic core, iieetullic flanges rigidly taste ed to the ends of bllQlHGtfllllC core, annular depressions in, said flanges firmly holding the fibrous core in place, eachof. said being of a single thickness and having a substantial. part of the surface eX- tending outwardly from the fibrous core substantially at right angles to the axes of the cores, while the peripheralportions of said flanges flare outwardly, whereby a bobbin of light weight and substantial strength is obtained, whichpermits the ready winding; or unwinding of yarn without'the formation of soft spots.
In testimony whereof, he has hereunto subscribed his name.
CHARLES WILFRED PALMER.
