TYPEWRITING acrame.

Application filed October 23, 1923. --Seria1 N'o. 6*?0362,

distended, to the curvature of the platen,

but which, by reason of its resiliency, firmly clasps the platen when positioned thereon, and having a resilient finger or clip extending longitudinally of the platen from the base-piece for holding a card or label to the platen. In such devices, the holder-basepiece may be of variable width, but, for

'firm attachment to the platen,'is preferably of such width as to embrace slightly more than half the circumference of the latter, so as securely to grip the same. In operation, the'edge of the card, usually theupper edge, is inserted under the finger .or clip of the holder, a-nd'is so held'to' the platen by the spring-pressure of such finger or clip thereon that the card or label will move with the platen as the latter is rotated and has its line-feed movements. Holders of this character ordinarily permitof complete rotation of the platen, so that the card or label may be inserted under the finger or clip of the holder, and the card carried rearward around the platen and up under the usual pressure-rolls to the printing-position; the pressure-rolls assisting in holding the card or label during the printing-operation.

Heretofore the card-engaging finger or clip of the holder has beenyof the same material as the basepie-cc; the two parts being stamped as a unit fromthe same sheeting. The functions of the two parts of the holder being different, it is not alwaysdesirable to have these parts of the same material, or of the same flexibility and resiliency; and, where they have been madein a single piece or of the same material, it has happened that the finger-piece or clip has been easily distorted and rendered unreliable; incidentally rendering worthless the entire de-- vice.

A feature of the present invention is a construction of'holder wherein the baseplece and finger-p1ece or clip are separately made; each of a. material, flexibility, and

resiliency best suited for its particular functions. A further feature of the invention is an attaching means for the finger to the base-piece such thatthe fingerlmay be readily and securely attached to and mounted upon the'basc-piece, in positionforproper engagement with the platen; and such that one finger-piece or clip may be readily substituted for another,if desired, without loss of the more, expensive base-piece. v

"Other features and advantages willhereinafter appear.

In the accompanying drawings, Figure 1 is a perspective view showing the card-holding device in operative position on the platen of a typewriting machine. j p 1 I Figure 2 is an end view of the structure shown in Figure 1, a type-bar being also shown in striking position.

Figure 3 is a view, in front elevation, showing the card-holding device in operative position on the platen. Figure 4 is a view in longitudinal cross section through the card-holding device.

A label-holder 10 is shown as applied to a rotary platen '11, which maybe the platen of any standard typewriting machine; The holder 10 is shown as a piece of resilient sheet-metal, preferably spring-brass, which,

when removed from the platen, has a tendency to contract, but which, when distended by the platen, assumes the curvature of the platen and snugly embraces it. The holders tendency to. contract causes it to grip the platen in such manner as to beheld thereto without slippingfand so that, without any extraneous holding means, 'itwill holder is cut away at 12, 13, at the front and rear thereof,'to form tongues 14:, 15, 16 and 17. The relatively narrow width of these tongues assures proper flexibility of the same. I

About midway of the front and rear edges ofthe holder 10, and spaced apart longitudinally of the platen, are a pair of straps 18 and .19, stamped up from the body of the holder. To the right of the strap 19 and to the left of the strap 18, are holes 20 and2l, respectively, through the holder. A card-hold ing clip-finger 22, preferably of spring-steel, is secured to the holder 10 by passing the lefthand end of such finger under the strap 18, up through the opening 21 in the holder over the outer face of the holder to the hole 20, down through the hole 20, and under the strap 19. To permit of such placement of the finger 22, thesame is bowed slightly upward at 23 between the holes 20 and 21. The finger 22, below the strap 19, has a pocket 24 therein, to receive a detent 25, pressed out of the strap 19. VVhen the detent 25 is in the pocket 24, the linger 22 is held against accidental longitudinal displacement. frontand rear offsets of the straps 18 and 19 prevent angular displacement of the clipfinger. v

As shown in Figure 4, the finger has a natural set or bend 26 between the righthand edge 27 of the holder-proper and the distal end 28 of the spring. By'reason of this bend and of theresilient material of which the finger 22 is made, the finger will press throughout its length, between the holder 10 and the distal end of the finger, against the platen. In use, the upper edge of the card 29 is inserted under the finger 22, and is held to the platen by the spring pressure of'the finger, so that, as the platen revolves, the card may make a complete revolution therewith if desired. Once the card is in position under the finger, it is only necessary to turn the platen until the lineposition at which it is desired to type thereon is brought to the printing-line of the platen; the printing-position on the platen being indicated in Figure 2 by a type 30.

' Variations may be resorted to within the scope of theinvention, and portions of the improvements may be used without others.

Having thus described my invention, I claim:

1 1. In a typewriting machine, the combination with a rotary platen, of a card or label holding device comprising a plate of resilient sheet-material curved to conform to the curvature of the platen when the holder is distended, and of such width as securely to clasp the platen by reason of such resiliency, and a resilient clip-finger set and secured to The . for typewritingmachines comprising a plate of spring brass curved to conform to the curvature of the platen when the holder is distended, and of such width as securely to clasp the platen by reason of its resiliency, and a spring-steel clip-finger set and secured to the plate and projecting laterally therefrom in such direction as to extend longitudinally of the platen when the attachment is in use.

3. A card and label holding attachment for typewriting machines comprising a plate of resilient sheet-material curved to conform to the curvature of the platen when the holder is distended, and of such width as securely to clasp the platen by reason of such resiliency, a resilient clip-finger set to the plate and projecting laterally therefrom in such direction as to extend longitudinally of the platen when the attachment is in use, and a pair of straps spaced apart on the plate longitudinally of the clip-finger for holding the latter; the clip-finger being passed under one strap, thence through a hole in the plate to the outside of the latter, and thence through another hole in the plate to the run der sideof the second strap. 7

4. A card and label holding attachment for typewriting machines comprisinga plate of resilient sheet-material curved to conform to the, curvature of the platen when the holder is distended, and of such width as securely to clasp the platen by reason of such resiliency, a resilient clip-finger set to the plate and projecting laterally therefrom in such direction as to extend longitudinally of the platen when the attachment is in use, a pair of straps spaced apart on the plate longitudinally of the clip'finger for holding the latter; the clip-finger being passed under one strap, thence through a hole in the plate to the outside of the latter, and thence through 'another hole in the'plate to the under side of the second strap, and a detent on the second strap for lnterloclnnent with a pocket in the clip-finger.
