RIBBON ATTACHMENT ESPECIALLY ADAPTED FOR TY-PEW'RITERS.
Specification of Letters Patent. Patented J n 6 1922 Application filed September 3, 1921. Serial No. 498,213.
To all whom it ma concern:
Be it known that MALCOLM L. OOSSITT, a citizen of the United States, residing at Alameda, in the county of Alameda and State of California, have invented certain new and useful Improvements in Ribbon Attachments Especially Adapted for Typewriters, of which the following is a specification.
My invention relates to means for conveniently attaching a typewriter ribbon, and
holding it under proper tension during the period of its use. More especially, my invention is applicable to manifolding ribbons as applied to that type of manifolding attachments for typewriters, in which one or more manifolding ribbons are carried by movable arms and are adapted by the movement of said arms to bethrown into functional position between the sheets of paper, in the line of type-impact, and to be removed therefrom to inoperative position out of the way.
It is in this special relation that, for the sake of illustration, I shall herein disclose my invention, .though it is to be understood that I am not to be confined to this use, as the invention may be applicable to any use or in any connection in which a ribbon is to be stretched under tension between carrying members.
In manifolding attachments for typewritersflwhich comprise a frame adapted to be conveniently secured upon the platencarriage of the machine, movable arms carried by the frame, and located in the vicinity of the ends of the platen, and one or more single length manifolding ribbons carried by and between said arms, certain essentials are necessary for the successful employment of such ribbons. One is that their connec tion with the arms shall admit of their ready attachment and detachment, since, inthe nature of thin s, their life is limited. Another is that w en applied they shall be under tension, in order that their type impressions may be clear and distinct, and, further, that this necessary tension shall be capable of being restored, if, for any reason, the tend to slacken.
S till vanother essential is that, since their use in the general scheme of the manifolding operation involves their presentation to type-impact along vdifierent longitudinal lines in order thafijtheir entire width may be utllized and thus prolong their life, it is necessary that their end connections be such that in whatever line position they may be, the tension shall be uniform throughout their Width.
These and other objects are sought to be attained by my invention, and with these ends in View my invention consists in the novel attachment which I shall now fully describe, by reference to the accompanying drawings, in which- Fig. 1 is a plan view, showing, eral way, a manifolding device for a type writer, said device carrying a single ribbon. F 1g. 2 is a section on the line 22 of Fig. l, the dotted lines showingthe elevated or non-functional position of the ribbon.
Fig. 3 is a ribbon attachment, F ig, 4 is a face elevation, enlarged, showing the connection between the ribbon-clip and the carrying arm, at one end of the ribbon.
Fig. 5 is an elevation of the inclined end of the carrying arm. I
Fig. 6 is a section on the line 6-6 of Fig. 4:. Fig. 7 is a rear elevation, enlarged, showlng the connection between the ribbon clip and the carrying arm, at the otherend of the ribbon.
Fig. 8 is a section on the line 88 of Fig. 7.
Fig. 9 is a perspective view of one of the ribbon clips.
Referring to Fig. 1, the numeral 1 indicates the frame of a typewriter, 2 thekeys, 3 the platen carriage, 4 the platen, 5 the spacing ratchet, 6 the main ribbon, 7 the ribin a genperspectlve view, showmg my bon drums, 8 the spacing lever, 9 the paper It will now be seen by reference to Fig.v 2, thatby swinging the arms 13 down with the rod 12 as an axis, the manifolding ribbon will be brought down to a position in the line of type'lmpact, and by swinging the arms up, the ribbon will be carried up to a position above the platen, as seen by the dotted lines. y
The typewriter and the manifoldlng attachment here shown are merely illustra4 tive, it being understood that these may be of varied forms, the only essential being the employment of carrying members and a ribbon stretched between them.
My present invention is particularly illustrated in Figs. 3 to 9. From these it which it is to be connected. In the fold or crease of each clip hook are made a plurality of holes 17 adapted to receive the locking tongues of the arm ends, when the hook of the clip is slipped upon said end. lhe clips may be secured to the ribbon in any suitable manner, a, good form of connectlon being to interfold and press them together. The clips are thus permanently attachedto, and practically form a unitary part of the ribbon,-which is thus in condition to be readily attached to and detached from the arms The clips have 'a width about equal to that of the ribbon, but the an lar ends of the arms are longer than the width of the clips 'to afiord latitude for selective adjustment.
It will now be seen, as shown in Fig. 3, that if the clipped ribbon has a length sufficient to extend, under proper tension, between the arms when the clips engage the angular arm ends in a given section of said ends, the ribbon, if it subsequently slackens, can have its proper tension readily restored by moving the clips to a different position on said ends. In the angular relation of said ends here shown, this adjustmentwould be from the extremity towards the base of said ends because the angle of said ends is a converging one; but if the. angles should be the other way, the direction of adjustment would be reversed.
It will also be seen that this adjustment can be made as delicate as may be found desirable, both by a predetermined spacing of the locking tongues and holes, and by moving either ribbon clip independently of the other if the adjustment be but sli ht, though in practice, it will probably be ound more desirable for the sake of keeping the ribbon straight, to move both clips uniformly.
The extentof the engagement of the clips with the arm ends being throughout the width of'the clips, it follows that as the clips and ribbon have about equal width, the
versible, and, therefore, adapting the ribbon for attachment in one way only,,no' mistake can be made in fitting the ribbon; and, therefore, the different colors will always be in proper place.

6. A ribbon attachment comprising a carrying member having an inclined end; a ribbon; a clip secured to the ribbon end and adapted to engage the inclined end of the carrying member; and means for locking said clip in varying positions along the length of the inclined end of the carryingmember, consisting of interengaging tongues and holes in said end and clip.
7. A ribbon attachment comprising a carrying member having an inclined end formed with a plurality of tongues; a ribbon; and a clip secured to the ribbon end, formed with an inclined hook adapted to fit upon the inclined end of the carrying member, said hook being perforated in its fold crease to selectively engage the tongues of the inclined end of the carrying member.
8. A ribbon attachment comprising a pair of spaced carrying members with inclined ends, the angle of one end being opposite to that of the other end; a ribbon; a clip secured to each end of the ribbon, each clip having an inclined hook adapted to fit upon the inclined end of the corresponding carrying member; and means for locking said hooked clip in varying positions along the length of the inclined end of the carrying member.
9. In a ribbon attachment adapted for typewriters, an impression ribbon having secured to its end a clip the outer portion of which is angularly folded to form, a hook and is perforated in its fold crease.
In testimony whereof I have signed my name to this specification.
