INKING-RIBBON FOR TYPEWRITERS AND THE LIKE Filed May 28, 1949 val-ER PL A x INVENTOIPI Patented Jan. 8, 1952 UNITED INKING' RIBBON FOR TYPEWRITERS AND THE LIKE Valer Flax, Vic-Fezensac, Gers, France Application May 28, 1949, Serial No. 95,943 In France January 11, 1944 Claims. (Cl. 197-172) The most outstanding of the drawbacks inherent in inking ribbons for typewriters, calculating machines and the like reside in the fact (1) that it is difficult for the uninitiated to secure the end of the inking ribbon to the spool inasmuch as the spacing of the two spool cheeks is generally insufiicient to enable the end of the ribbon to be passed in a convenient manner, at a definite point on the spool core adapted to receive the end of the inking ribbon or its clip, quite apart from the fact that the dirtying of the hands is unavoidable; (2) that the ribbon is, in general, prematurely perforated near its two ends due to the defective operation of the ribbon-winding means of the typewriter inasmuch as when a spool is unwound, the ribbon is arrested in its movement and the metal characters continue to strike at the same point of the ribbon until the typist sets the winding mechanism going again.

The present invention overcomes these drawbacks and enables even non-specialized persons to secure the ribbon to the spool in a very convenient manner, without dirtying their fingers, whether the end of the ribbon is provided with a non-inked extension or not. 7

For a better understanding of the invention and to show how the same may be carried into effect, reference will now be made to the accompanying drawing, in which:

Fig. 1 is a perspective view of the end of an inkin ribbon formed into a simple loop.

Fig. 2 is a'similar view to Fig. 1 showin the end-loop of the ribbon passed over the winding spool of a typewriter.

Fig. 3 is a perspective view of the end of an inking ribbon formed into a running loop.

Fig. 4 is a view similar to Fig. 3, but showing a variant.

In the following description and the accompanying drawing it has been assumed that the end of the inking ribbon is provided with an extended portion bearing no ink, made for example, of Celluloid, cellophane, fabric of any kind or like material. However, it is to be understood that the principle of the invention is also applicable when the end portion of the ribbon is constituted by the inked ribbon itself.

In Figure l, the end of the ribbon is formed into a loop 4 and is attached as by a rivet 3 to the ribbon 2. The loop is sufficiently large to enable a whole spool to be inserted therein, including its two flanges. The strip carries on the inner face of the loop 4 a hook 5 by means of which the loop is to be secured to the core of the spool. The tip 6 of the hook is directed away from a slider member 1 through which pass the two strips l and 2 of the loop. This slider is adapted to be moved along the two strips l and 2 by means of a tag 8, secured to the said slider. p

In Fig.2, the end loop is shown hooked on to the core ll) of a winding spool. In order to secure the ribbon to the core, the spool is passed through the loop and the slider l is brought into contact with the core so as to tighten the loop around the core. The slider is sufficiently narrow to prevent the loop from becoming loose of its own accord. When in position, the hook is inserted into the opening 9 of the core I0, thereby preventing the core from turning freely in the tightened loop. In order to withdraw the spool from the loop in a convenient manner, it is simplynecessary to pull the slider 1 towards the rivet 3 by means of the tag 8 so as to render the loop suificiently wide to enable the spool with its flanges to be withdrawn therefrom.

Fig. .3 shows a running loop adapted to be tightened around the spool core by pulling on the ribbon 2. The ribbon is doubled over at I l and [2. The slider is passed through the folded portion l3. Said slider is narrow but sufiiciently wide, nevertheless, to enable the loop 4 to be tightened or loosened. Near the point II, the

.ribbon is provided with a hook 5 by means of which the loopis attached to the spool. The end 8 of the ribbon constitutes a tag with which the hook may be readily moved to tighten or loosen the loop about the core. The hook 5 is located inside the loop 4, its tip facing away from the slider l. The loop may be enlarged or tightened to permit the introduction therethrough of a typewriter ink-ribbon spool, including both its flanges, with a view to fitting the loop around the spool core, or for removing it from said spool.

When pulling on the ribbon 2 in the direction of the arrow, the loop is tightened around the core. The book engages the opening provided for this purpose in the core as the loop is tightened. When it is desired to remove the ribbon from the spool, it will simply be necessary to pull on the tag 8 in order to withdraw the hook from the opening in the core and at the same time loosen the loop.

The operation of the running loop shown in Fig. 4 is the same as that shown in Fig. 3. In this form of embodiment, the ribbon is secured by a rivet 14 to an arcuate member 15 in the form of a saddle, the width of which corresponds to the distance between the two flanges of the spool of a typewriter (not shown here). The arcuate member I5 snugly fits the spool core in its operative position. On its hollow face, a hook 5 is stamped out of the body of the member 15, The ribbon is passed through a notch 5 which serves as a slider for the ribbon. To secure the ribbon to the spool, the loop is enlarged so as to enable the spool with both its flanges to pass therethrough. The loop is then tightened by Pulling on the ribbon 2 pass ing through the notch l6 and at the same time the arcuate saddle member I5 is pressed with its hollow portion against the spool core. The

hook 5 penetrates into the aperture formed in the core and its position is thereby fixedrelatively to the spool.

To remove the ribbon from I the spool, it will simply be necessary to pull on the end 8 0f the ribbon, thereby unhooking the hook 5- from the core, and atthe same time loosening the loop 4 sufiiciently to enable the spool and its two flanges to berernoved.

I claim:'
