Patented Mar; 3, 1942 g g i s PATENT o Flci- UNITED STATE sroor. ronjnnmisrvu TAPE Octave Le Clair Valentine, Devon, Conn, assign or to Parke, Davis acompany, Detroit, Mich, a corporation of Michigan Application m 22, 1939, Serial No. 275,661 I 4 Claims. (oi; 242-71) The invention relates to spools for holding adhesive plaster or the like, and has a special reference to that typecomprising a tubular core on which the adhesive plaster or other material is wound and disk-shamd heads which are secured to the core either prior or subsequent to the winding of the plaster thereon. It is the object of the invention to obtain an improved construction facilitating the application or the heads to the core and insuring a ri id attachment thereto. It is a further object to obtain a construction which prevents expansion of the core during as= sembly oi the heads therewith and which also guards against any? dishing of the heads or defiec ,tion from the radial plane thereof. Still further,
it is an object to obtain a construction which is simple in design, economical to manufacture and presents an attractive appearance. these objecm in view, the invention consists in the construction as hereinafter set forth.
in the drawings:
Figure 1 is a central longitudinal section showing my improved spool with one of the heads attached thereto and the second head detached;
Figure 2 is a similar view of a slightly modified construction;
Figure 3 is a similar view showing the spool complete and with the outer cylindrical closure applied thereto;
Figure 4 is a perspective view of Figure 3;
Figure 5 is an enlarged sectional view showing the manner of securing the head to the core;
Figures 6 and 6A are respectively a central longitudinal section and a side elevation of one of the heads;
Figures 7 and 7A are similar views of the core;
Figures 8 and 8A are similar views showing a modified construction of core.
A is'a tubular core member of any suitable material, but preferably consisting of a sheet metal blank bent into a cylindrical form. The
opposite ends of this core member crammed with rounded beads B preferably turned inward so as to leave an unbroken outer cylindrical surface. The inturned portions may be either continuous as shown in Figure 8, or may be ser rated as indicated at B, Figure 7, to facilitate turning. Also, the core may be either formed with a. seamed joint between the opposite ends of the blank, as shown at C in Figures '7, Mind 3, or with a butt Joint D as illustrated in Figures 1, 2, 8 and 8A. E are the disk-shaped heads preferably formed with a peripheral inturned portion forming a bead F. The heads are furtherias-hioned to provide a grooved seat G for With receiving the bead B at the end of the core member and with an axially projecting annular portion H for insertion within the head of the core member and adapted to be expanded into engagement therewith. There is also a. portion I which is laterally deflected from the general plane of the head and in which the portion G is formed. This results in the fog of an annular rib J which imparts rigidity to the struc ture as hereinafter set forth.
With the structure as thus far described, it will be evident that the heads E may be engaged.- with the opposite ends of the core member by inserting the portion H (at the left oi Figure 1). within the bead. lB-and seating said been in the annular groove G adjacent to the rib J. The
portion H may then be expanded by the use of any suitable. expanding tool which, with the construction shown in Figure 1, will turn it about the inner side of the bead, as shown on the right-hand side of this figure. .With the modifled construction shown in Figure 2 the portion H forms a continuation of the curved portion G, but is of a. diameter which will permit its inner end to pass within the bead B. it is then expanded to fit about said bead as shown at the right-hand side of Figure 2. Withboth constructions the direction of the expanding force is along the oblique line l--i, Figures 2 and 5.
" and in the direction or the arrows so that the core member either-before or after placing the adhesive tape or plaster thereon and after expension of the portions H or H these heads will be rigidly secured to the core. The structure is completed by a cylindrical cover member K preferably having beaded ends K and being formed of a size to permit of pressing over the heads. Depressed portions L in themember K will serve to frictionally lock with the beads F so as to hold the cover from accidental displacement while permitting of detachment at any time.
One important advantage of my construction is that the heads are not dished or warped by the operation of attaching the same to the core. This is for the reason that the thrust occasioned by the expansion of the inserted portion against the core is resisted by the rib J and without radially expanding the latter. Consequently, the disk remains in its original plane without warp- .ing or dishing to either side.
eat G, as shown in Figures 1 and 2, I may use interrupted depressions forming an interrupted grooveseat as indicated at G, Figures 6 and 6A.
What I claim as my invention is:
1. A spool comprising a tubular core member having a' beaded end, a disc-shaped head fashioned with an undercut groove portion-constituting a seat for the beaded end of the core, with a portion of said seat radially outward fromand surrounding said bead to hold said core against radial expansion, said head also having a portion inserted within said bead with its inner end expanded into locking engagement therewith.
2. A spool comprising a tubular core member provided with a beaded end, a disc-shaped head having a peripheral reinforcing bead and a central laterally offset portion fashioned with an undercut groove constituting a seat for said beaded end, with a portion of said seat radially outward from and surrounding said bead to hold said core member against radial expansion, said head also having a portion inserted within said head with its inner end expanded into looking engagement therewith.
3. A spool comprising a tubular core member provided with a Ibeaded end, a disc-shaped head having a peripheral reinforcing bead and a central laterally ofl'set portion fashioned with an undercut groove therein forming a seat for said beaded end, a portion of said seat together with said oflset portion forming a surrounding reinforcing rib for holding said core member against radial expansion, said head also having a portion inserted within said bead with its inner end expanded into locking engagement therewith obliquely opposite said seat.
4. A spool comprising a tubular core member having an inturned rounded bead at an end thereof, a disc-shaped head having an annular portion inserted within said bead with its inner end expanded into locking engagement therewith, said head also having an undercut groove therein constituting a seat for said bead, and a portion surrounding said bead fashioned to resist radial expansion of the latter, thereby preventing I warping of the head.
