End portions I8 are preferably formed integrally with the reduced end portions I3 and keyed to the bushings IT as at I9 to prevent rotation of one with respect to the other thereof. It will be observed that the overall axial length of each of the bearing members I3 and I4 is considerably less than half the length of the drum-forming element I.

A sleeve I9, formed of sheet metal or the like and preferably having its opposite ends backturned upon itself as at 2|] for the purpose of reinforcement, i next inserted into the drumforming element I and the bearing assemblies I3 and I4 are inserted into opposite ends thereof, whereby to cause the reduced ends I5 to be tele- 'scopically received in opposite ends of the sleeve I9 and the bushings IT to be received within the counterbored opposite ends] of the drum-forming element I in contact with the shoulder 5 thereof. Retainer plates 2| are then'inserted into the counterbored ends of the drum-forming element I in contact with the heads I6, particularly portions I1 and I8 thereof. Finally, the opposite ends of the drum-forming element I are peaned over the retainer plates 2| at circumferentiallyspaced points as indicated by the numeral 22 (sec particularly Figs. 5 and 6).

It will be noted that the reduced end I5 of bearing I3 is provided with tapering walls 23 for the reception of a tapered spindle, wherea retainer plate 2I and end portion II} of said bearing I3 are provided with aligned keyways 24 and 25 respectively for the reception of a keyed spindle.

In Fig. 9, we have illustrated a modified form of bearing assembly, identified in its entirety by the numeral 26 and including a tubular reduced axially inwardly-projecting portion 21 having an integrally-formed radially outwardly-projecting head 28. The bearing portion 21 is formed preferably from nylon or the like. The head 28 is provided with a radially-projecting flange 29.

An annular mounting plate 30 receives the head 28 axially inwardly of the flange 29; whereas a cooperating mounting plate 3I having an annular notch 32 therein for the reception of the flange 29 is positioned axially outwardly thereof. As shown, the head 28 is provided with a toothed portion 33 receivable within a notch 34 in the mounting plate 30. Rotation of the bearing 2'! with respect to the mounting members is prevented in this manner. On their peripheral edges, the mounting plates 30 and 3I are provided with aligned slots 35 and 36 respectively into which fingers 31, formed integrally with retainer or facing plates 38 are positioned. It will be noted that the extreme inner ends of the fingers 31 are bent axially inwardly over the mounting plate 30, so as to lock all the elements together. This structure has the advantage of being able to be assembled as a unit and thereafter placed in position in the counterbored opposite ends of the drum-forming element I and finally locked in place therein by peaning or the like, as indicated by the numeral 32 of Fig. 5.

While we have disclosed and claimed a novel spool and method of forming same, it should be obvious that the same-iscapable of modification without departure from the spirit and scope of the invention as defined in the appended claims.

What we claim is: r

1. The method of forming a spool which comprises forming circumferentially-extended channels in the outer surface of a cylindrical drumforming element in closely spaced relation to the slightly less than the diameters of said ribs, placing said flange-forming elements over said reduced ends with the ribs thereof in engagement with the inner walls of said channels, thereafter expanding said opposite outer ends to their normal diameters to lock said ribs in said channels, forming a pair of annular bearing members having enlarged heads capable of being snugly received within the counterbored opposite ends of said drum-forming element and reduced inner end portions, the overall axial length of said bearing members being considerably less than half the length of said drum-forming element, placing within said drum-forming element a tubular sleeve having an internal diameter approximating that of the external diameter of the reduced portions of said bearing members, inserting said bearing members into the opposite ends of said drum-forming element whereby to cause the reduced end portions thereof to be telescopically received within said sleeve and to cause the enlarged heads to be received within said counterbored portions in engagement with the shoulders thereof, and thereafter creating locking engagement between said bearing members and said drum-formin element.

2. The method defined in claim 1 in which said locking engagement 'is caused by peaning the opposite ends of said drum-forming element over the. adjacent heads ofsaid bearing members.

3. The method of forming a spool which comprises forming circumferentially-extended channels in the outer surface of a cylindrical drumforming element in, closely spaced relation to the opposite ends thereof, counterboring said opposite ends of said drum-forming elements whereby to form annular shoulders axially inwardly spaced from said channels, providing flangeforming elements with central openings having maximum diameters corresponding to the external diameter of said drum forming element and central radially inwardly projectin circumferentially extended ribs corresponding in width and depth to the channels in said drum-forming element, deforming the opposite ends of said drum-forming element whereby to uniformly reduce the diameters thereof axially outwardly of the inner walls of *said channels to diameters slightly less than the diameters of said ribs, placing said flange-forming elements over said reduced ends with the ribs thereof in engagement 7 with the inner walls of said channels, thereafter expanding said opposite outer ends to their normal diameters to lock said ribs in said channels, forming a pair of annular bearing members having enlarged heads capable of being snugly received within the counterbored opposite ends of said drum-forming element and reduced inner end portions, placin within said drum-forming element a tubular sleeve having an internal diameter approximating thatof the external diam- 5 6 eter of the reduced portions of said bearing memv References Cited in the file of this patent bers, inserting said bearing members into the UNITED STATES PATENTS opposite ends of said drum-forming element whereby to cause the reduced end portions there- Number Name Date of to be telescopically received within said sleeve 5 232359 Graham sept' 1330 and to cause the enlarged heads to be received 19051760 Workman 10, 1911 within said counterbored portions in engagement 1742'454 Van Delhofi 1930 with the shoulders thereof, and thereafter cre- 1,758,229 e May 13, 1930 ating locking engagement between said bearing 1,934,170 Crooks 7, 1933 members and said drum-forming element. 2,190,035 5011011 1940 FREDERICK J BIEBER 2,545,527 Maxwell Mar. 20, 1951 LYLE OVERHOLT 2,593,069 Steinmetz Apr. 15, 1952
