RIBBON-SPOOL.
Specification of Letters Patent.
Patented Dec. 1 2 1905.
Application filed March 25, 1905. Serial No. 252,061.
.ful Improvements in Ribbon-Spools, of which the following is a specification, reference being had therein to the accompanying drawlngs.
This invention relates to a ribbon-spool, and particularly to a construction of hub for a spool of this character used in connection with type-writing machines.
The invention has for an object to provide an improved construction of the hub comprising separate members disposed one upon the other and one of greater length than the other, whereby a shoulder is formed against which the opposite heads of the spool are disposed and secured by the free end of the other or inner hub member.
A further object of the invention is to provide the outer hub member with a shoulder or extension for the purpose of receiving a securing device attached to the ordinary ribbon, which extension, being tagentially disposed, may be readily engaged with the securing device carried by the ribbon.
Other and further objects and advantages of the invention will be hereinafter set forth, and the novel features thereof defined by the appended claims.
In the drawings, Figure l is a perspective with parts in section; Fig. 2, a central vertical section through the hub; Fig. 3, a horizontal section on the line 3 3 of Fig. 1; Fig. 4, a perspective of the blank from which the inner hub is formed; Fig. 5, a similar view of this hub bent into tubular form; Fig. 6, a perspective of the blank from which the outer hub member is produced; Fig. 7, a similar view of this member bent into form; Fig. 8, a perspective of the hub members assembled, and Fig. 9 an elevation of one of the spoolheads.
Like letters of reference refer to like parts in the several figures of the drawings.
The letter A designates a blank of sheet metal from which the inner hub member is formed by bending the blank into tubular form, as shown in Fig. 5, with the free side edges of the blank in contact, as at A. The
outer hub member is produced from a blank (shown at B in Fig. 6) which has one end thereof slightly upturned, as at B, and beveled, as at B to produce a sharpened edge. This blank is then bent into tubular form (shown in Fig. 7 and the square end thereof projected tangentially, as shown at B while the beveled edge B permits ample space between it and the end B for the introduction of the securing device carried by the ribbon. This device may be of any suitable character-for instance, a hooked member D to engage the tangential projection B and provided with a ribbon-clip D thereon to engage the ribbon D as shown in Fig. 2. The outer hub member B is of less length than the inner hub member, thus providing at its opposite ends shoulders 13*, against which the heads O, disposed at the opposite sides of the spool, are adapted to contact and to be secured by the overturned extended ends of the inner hub, as at A These heads may be of any desired character, depending upon the particular application and construction of spool involved, and are here shown as composed of sheet material provided with a circumferential strengthening-boss O stamped therein and with peripheral teeth O for engagement with any desired driving means for the spool.
In assembling the hub the tubular members are disposed one within another and the heads applied and secured by a simple bendingover of the opposite ends of the inner hub, thus producing a hub in which the parts may be formed of sheet material readily bent intoshape by machinery and secured in assembled relation by a simple operation. This obviates the necessity of milling, boring, and slit- Having described my invention and set forth its merits, What I claim, and desire to secure by Letters Patent, is-
1. A spindle for typeriter ribbon-spools comprising two tubes, the outer one being shorter and embracing in solid contact the inner tube, a portion of the outer tube being deflected tangentially from its remaining portion.
2. A ribbon-spool fortjzpe-writers having its heads formed as centrally-apertured disks, an inner tube fitting and passing through said apertures and upset at each end against the outer surfaces of the disks, and an outer tube mounted in solid contact upon the inner tube and extending from the inner surface of one disk to that of the other.
3. A spindle for type-Writer ribbon-spools comprising two tubes, the outer one being shorter and embracing in solid contact the 1nner tube, a portion of the outer tube being deflected tangentially from its remaining portion and the adjacent remaining portion being beveled at its end opposite the deflected portion.
4. An outer member for type-Writer rib-
