Claims.
This invention relates to improvements in metallic bobbins, spools, and the like such as are employed in the textile industry.
The textile industry is employing an everincreasing use of metal equipment to replace equipment constructed from wood, ceramics, and various synthetic plastics, 'The light metals and their alloys, such as magnesium, aluminum, and alloys thereof, find ready adaptability in the textile industry for this purpose in view of their inherent weight-saving property as well as their resistance to mechanical wear and chemical corrosion.
For the most part, metallic textile equipment now in use, such as spools, bobbins, pims, and the like, have been constructed from sheet metal that has been formed to shape, seamed or welded, and thereafter provided with flanges attached to the formed sheet metal body by screws or other fastening members. Such equipment is insufficiently sturdy in its construction to withstand the abuse arlsingout of the high speeds of operation of textile equipment employing these instrumentalities, the increase in speeds being a direct result of the weight-saving factor derived from the use of light metals and their alloys. Further, it is inherently difficult to dynamically balance such equipment, particularly at high operating speeds, in view of the seams, joints and welds, which introduce unsymmetrical or eccentric loading conditions.
It is an object of this invention to provide a textile bobbin of sturdy construction which will have all the advantages of light weight construction, will retain its dynamic balance over long periods of service, and will at the same time be economical in its production.
It is a further object of this invention to provide a spool or the like having a minimum number of parts and which may be produced from commercially fabricated stock.
Further objects and advantages of the invention hereinafter described in more detail will be manifest from a consideration of the speciflcation when taken in the light of the drawing appended hereto, in which:
Fig. 1 represents an elevational view, partially in section, of the body or barrel portion of a preferred spool;
Fig. 2 represents an end view of the body or barrel illustrated in Fig. 1;
Fig. 3 represents a fragmentary sectional view of a spool having a flange disposed at its end;
Figs. 4 and 5 represent fragmentary sectional securing a flange to the body or barrel of the spool, bobbin, or pim of this invention; and
Fig. 6 represents a fragmentary end view of the flanged spool of this invention.
Referring to the drawing, the body or barrel of the spool of this invention is made from a standard commodity preferably inthe form of cylindrical tubing ill having internal ribs ll formed integral with the wall of said tube. As will be evidenced from an inspection of Figs. 1 and 2, the ribs II are preferably circular in cross-section and are connected to the inner surface of the tubing 10 by means of a relatively short connecting web I 2. This form of internally ribbed tubing readily lends itself to fabrication by an extrusion process which permits the fabrication of relatively thin-wall tubing having integral internal ribs ll connected to the rela tively thin wall through the medium of the short connecting webs I2.
The internally ribbed tubing l0 may be produced in any desirable length by an extrusion process as a stock commodity, and in the construction of the spool of this invention sections of tubing are cut to the desired length of spool required. To prepare a section of tubing for subsequent fabrication of a .flanged spool, the wall I4 is removed, as by a cutting or latheturning operation, to expose extending portions of the aforementioned ribs Ii at both ends of the body or barrel portion III of the spool. In view of the relatively short connecting webs l2, it will be noted that the exposed portions of ribs I I (Fig. 2) will be substantially circular in cross-section.
Referring particularly to Fig. 3, a flange l5, which may be a flat plate or disc, or formed with a central hub I8, is provided with apertaxes I! which serve to support the flange on the extending ribs H, the apertures obviously being equal in number to the ribs H. The length of the extending portions of ribs H is so selected in'respect to the thickness of flange -i5 to provide sufficient metal to head up the rivets as illustrated in Fig. 4, or form a countersunk head as illustrated in Fig. 5, the flange IS in either one of the aforementioned heading operations illustrated in Figs. 4 and 5 being then secured to the body III of the spool, bobbin. pim, or the like. Four internal ribs II have been illustrated as representing the preferred embodiment of the structure of the invention,
1 although any suitable number of equally spaced ribs may be used. Also the internal ribs II views illustrating twomodes of construction for have been illustrated as generally circular in cross-section. Ribs of circular cross-section are preferred in that in this form they. present cylindricalrivet shanks which lend themselves both to accurate fltting with respect to the apertures 11 in flange I 5, as well as standardized button or countersunk heading tools and operations. Manifestly, any satisfactory number of ribs ll may be employed, and the internal ribs could have a cross-section other than circular without departing from the scope and intent oi. this invention. In this connection, the amountof metal in the extending ribs II should preferably be just suiiicient to flll out the selected rivet heads.
The flanged spool of this invention, which has been described hereinabove, permits the use or exceedingly thin metallic tubing, since the internal ribs il react to reinforce the wall of the spool body, which might otherwise be entirely too thin. The flange IS, in combination with the riveting operation for securing the same to the spool body, results in a sturdy spool assembly which withstands the vibrations experienced by such equipment at the high speeds of operation permissible with light weight spools. Also, the absence of seams, welded joints, and flange-connecting in- ,strumentalities permits 01 a spool structure which will retain its dynamic balance over long periods of use. Magnesium, and itsalloys, has been found exceedingly satisfactory, both in use in the textile industry as well as a source of extruded tubular spool bodies and forged or stamped flanges. their alloys, however, fully meet the requirements for the production of equipment inaccordance with the spool of this invention.
Although the invention has been described in terms of a particular spool construction, it is to be understood that the invention should not be limited thereto, sinceit will be manifest that the invention may be incorporated in other forms-of textile equipment without in any way departing from the scope of this invention as defined in the appended claims.
