RIBBON SP OL; 1,-
' Application filed August 17, 1925'. sefiatmsPte,5e-.i
This invention relates to ink ribbonspools of the kind referred to in companion applications Serial No. 52,503 and Serial No. 52,505, filed August 26, 1925.
5 The object of this invention is to provide simple means for securing the edges of the spool together upon in a manner which will prevent substitution of a new ribbon when the original ribbon 1 becomes worn.
The invention is adaptable for use with a spool of the kind set forth in my companion applications mentioned, which is of a special construction, to cooperate with parts 15 of a ribbon mechanism for certain purposes, and one of the objects of this invention is to construct the spool and to fasten the rib bon thereto in such a way that when the ribbon. is worn out the spool and ribbon must be thrown away and entirely replaced. instead of simply replacing the ribbon on the spool. 7
Referring to the drawings,
Fig. 1 is a view of the spool blank before it is bent into spool shape and showing one embodiment of the invention.
Fig. 2 is a similar view showing another embodiment of the invention.
Figs. 3 and 4 are sectional views showing spools made from the blanks of Figs. 1 and 2 respectively.
Figs. 5 and 6 are detail views of modification of the invention.
Referring to the drawings, the spool is made preferably of light gauge metal from a blank 7 which stamped therein in accordance with the invention of my companion applications and is also provided at its edges with interengaging prongs and openings to secure the edges together upon an interposed ribbon 9. In Fig. 1 triangular shaped prongs 10 are stamped from the blank adjacent one edge to project inward of the spool, and oblong openings 11 are stamped in the margin 12 at the other edge of the blank to receive said prongs. The margin 12 is depressed or ofi'- set 'to lie in a plane below that of the remainder of the blank so that when the blank is shaped in the form of a spool, as shown in Fig. 3, the margin will be depressed to receive the pronged edge of the blank, and the end of the ribbon, so that the outer surface of the spool will be uniformly concentric with the center. In Fig. 1 the prongs another the end of the ribbonhas the parallel openings 8 are. stamped theblank lengthwise thereof and the openings ll are oblong in shape and extend lengthwise of the blank to receive the. prongs, the openings being of ust sufiicient size to accommodate the prongs- In Fig. 2 the prongs 13 are stamped from the-blank transversely thereof and the oblong openings 14'extend'transversely of the blank to receive these prongs. In Figs-5-and 6 the prongs 15 are of rightangle shape and extend lengthwise of the blank, which will be-provided with openings like 11, Fig. 1, to receive these prongs. In assembling a spool made from the blank of Fig. 1, the blank is formed in spool shape, the end of the ribbon is laid upon the depressed margin 12, and the prongs are forced through the ribbon and projected through the openings 11, after which the prongs are bent upward against the underslde of the depressed margin 12 to clinch the prongs and to secure the edges of the spool together upon the interposed ribbon. These prongs are bent beneath the opening formed when the prong is stamped out to block the opening on the underside of the spool so that it will be impossible to insert a pin or wire or other device through the opening formed by stamping the prong and the registering opening 11 to secure a replacement ribbon upon the spool.
The spool of Fig. 4 is formed from the 1 blank of Fig. 2 in the same manner as here-. inbefore described in connection with the spool of Fig. 3; and a spool will be formed from such a blank as is shown in Figs. 5 and 6 in the same manner. The long side of the right angle shaped prong 15 is presented to the ribbon. as the latter is inserted between the overlapping portions of the spool and this prong presents less obstruction to the insertion of the ribbon than the prong 13 of Fig. 2, and possibly of the prong 10 of Fig. 1. The spool is provided with an inwardly directed flange 16 to engage 'a driver of the ribbon mechanism for turning the spool, and also with a lug 17 at one end, which preventsthe spool from being arranged on the driver wrong end to, as more particularlyset forth in my companion applications.
