SPOOL AND BO BBIN COMBINATION Fild July 8, 1954 INVENTOR. 100/5 /7. Mom/v BY ATTORNEY 7 2,862,610 SPOOL AND nonBlN COMBINATION Louis H. Morin, Bronx, N. Y.', assignor to Coats & Clark,

Inc.,.New York, N. Y., a corporation of Delaware Application July 8, 1254, Serial No. 442,139

' i 4'Claims. or. 206 -47) This invention. relates to a spool structure, wherein means is provided for supporting and shielding a bobbin 'end portion of a spool showing a bobbin mounted therein,

and a label clement-for retaining the bobbin against displacement from thesp'ool.

Fig.- 2Iis a'partial end view of the'structure shown in Fig. l, with part of the construction broken away and in section; and a Figs; 3Iand4'are viewsfsimilar to Fig. l, on a smaller scale, showing modified forms of construction.

This application constitutes a COl'ltlIlllZltlOl'l-lll-Pflli of the structure disclosed in my prior application filed June 22,

1953, hearing Serial Number 363,309, now abandoned.

Myprescnh-invention deals with spool structures having spun-over; or'forrned, label engaging rims for securing labels at spool ends and, more particularly, with the utilization of structures of this type and kind, wherein the label element is further used in retaining a bobbin against displacement-from the spool end. As the bobbin is disposed at one end portion only of the spool, the present disclosure will deal solely with one end of the spool.

In illustrating one adaptation and use of my invention,

I have shown Figs. 1 and 2 a moulded spool structure,

comprisingan inner tube or cylinder 10, an outer tube or cylinderll ljoining the inner cylinder in circumferen.

tially spaced: radial ribs or wall portions 12, of the general contour noted in Fig. 2 of the drawing. The end of the spool has an outwardly flared rim 13 which defines, around the cylinder 11, an annular recess 14'for reception of the thread, asdiagrammatically illustrated at 15.- The outer surface of the rim is preferably provided with a series of circumferentially spaced ribs.16 forming corresponding recesses, as noted at 17 in Fig. 1 of the drawing.

. In the construction shown, the ribs 12 are disposed in wide'spaccd relation to the outer end portion 18 of the cylinder 11 to form a large annular chamber 19 outwardly of the ribs 12.

Extending into the chamber 19, the ribs 12 have other United States Patent- O l cc Y Patented Dec. 2, 1958 label element 24, is preferably made of a transparent or translucent cellophane and this label is held in position an outwardly extended. portion of the end 18 of the cylin-' der 11,.to facilitate insertion of the bobbin 21 intothe chamber 19 and arrangement of the label 24 in position on the

surfaces

22 and 23, after which, the flange or rim 25 is then formed.

In the use of the combined spool bobbin structure shown in Figs. 1 and 2 of the drawing, the label 24can be broken through the bore 26 of the bobbin 21 and, then, torn from the spool end to free the bobbin for removal from the chamber 19.

'1 n Fig. 3 of the drawing, 1 have shown a modified form of. construction and, in this figure, a moulded spool is diagrammatically shown at 27, the spool having-a label retaining flange or rim 28, similar to the flange or rim In this construction, a bobbin 29, generally similar to the bobbin 21, is mounted upon the end surface 'of the. spool 27 and .a label element, inthe form of a shell or casing 31, is employed, the element 31 having a cup-- ciently strong to support the bobbin against shifting move-' ment on thespool end.

The modification of Fig. 4 'dilfersfrom that ofFig. 3

- .only in the construction of the spool 34. The latter, ex-

circum'ferentially spaced ribs 20, generally T-shaped in cross-sectional form, as will appear from a consideration of Fig. 2 of the drawing. The ribs 20 reduce the size of the chamber 19 and form positioning guides for a bobbin 21 so that the bobbin 21 is centralized on the spool end, in the manner clearly illustrated in Fig. 1 of the drawing.

It will appear that th'elouter surface 22 of the bobbin I is in alinement with outer ends 23 of the ribs 20, thus producing alined

label supporting surfaces

22, 23, upon which a label disc '24.isadapted to rest. The label, or

cept for flange 28', is described in copending application Serial'Number 423,457, filed April 15, 1954, and for convenience, a brief description of the spool may be given here. it comprises a one-piece, integrally formed, all

plastic thread spool comprising a barrel 35 having a pair of flanged end portions, one of which is shown at 36, of such size as to provide a so-called deep .grooved spool capable of holding a substantial amount of thread.= The barrel, when viewed in cross-section, comprises an annular wall of substantial thickness. Each flanged end portion comprises a plurality of concentric annular grooves bore 44. The innermost groove 43 extends into the annular wall of the barrel for a distance (not shown) less v than half the length of the barrel, andthe-remaining grooves terminate as shown. Each adjacent pair of .annular walls is connected to each other by a plurality of circumferentially spaced, radially disposed ribs, one of which, for example, is shown at 45, each rib being located in a groove and being coextensive in length with the depth of the groove. The free ends of the walls and ribs lie" in the end face of the spool. f

The bobbin and bobbin retaining structures of Fig. 4.

are like that of Fig. 3 and are identified by similar but I primed reference numerals. With all modifications, the label element, in'addition to retaining the bobbin against accidental displacement from the spool, also provides a protective covering to'prevent dust and dirt from collecting upon the bobbin. In each case, too, the spool has a bobbin in association with it, and the bobbin carries thread correctly chosen with respect to-the thread on the spool. The purchaser thus I It will be appreciated thatthe particular spools shown n the drawings are illustrative. That of Figs. 1-2 is an lntegrally formed, all-plastic, light weight spool of pleasing over-all appearance. The circumferentially extending ribs 16 and recesses 17 on the periphery of the end portion of the spool provide a decorative effect and increase the attractiveness of the spooll The circumferentially spaced ribs 20 may be omitted in spools of smaller size, that in spools whose tube or barrel 11 has approximately the same diameter as the bobbin so as to enable the bobbin to fit snugly in the compartment in the absence of the ribs. Figs. l-2 illustrates the use of a compartment in an end portion of the spool for receiving the bobbin, while the spools of Figs. 3 and 4 show how the bobbin ma be disposed outwardly of the end face of the spool. Fig. 4

' further shows that spools too small to be provided wit a compartment may yet be enabled to carry a bobbin. if desired, the spools ofFigs. 3 and 4 may be provided with an extension engageable in the bore of the bobbin, as

set forth in said copending application.

As illustrated, and as will be understood, the spool construction is variable. In each case, however, a retaining element for the bobbin is provided which extendsacross the end of the spool and across the outer end face of the bobbin. Peripheral portions of the end of the spool are movable or deformable so that they overlap or extend over onto peripheral portions of the retaining element to secure the element to the spool end. The spool may be entirely or partially made of plastic and may be formed integrally or from two ormore pieces. A spool partially made of Dlasticcomprises one whose rims or peripheral flanged portions are of plastic. and in such case movable or deformable peripheral portions may be formed on such plastic portions if the latter are not adapted to be. moved.

In order to moveor fold the

flanges

25, 28, and 2% s over onto peripheral portions of the retaining element. it is preferred to heat the flanges and tofold them over by means ofa suitable forming tool such as is described in copending applications Serial Number 442,137, filed July 8, 1954, and Serial Number 442,138, filed July 8,. 1954.

Theretaining elements

24, 31, and 31 may be of paper, foil, cardboard, plastic, and the like. They may-have 'printed information on them and thus serve as labels as well as retaining'elements, and/or they may be transparent to expose .the bobbin to view, in which case they are preferably made of a material like cellophane or sheet plastic. If desired, bobbins may be supported at both ends of the spool. 1
