In certain classes of card work it is necessary to write upon the extreme top edge of the card and since in such casesthe cards are frequently of a form which permits of inter,- lockingfor unit filing and accordingly have projecting locking points o lt' peculiar shape, there is danger that the card will become entangled with the card guide, the ribbon vibrator, or the platen scale mechanism usually found in typewriting machines.

It is, therefore, the purpose of this invention to provide a'card holding strip which 7 ,I I I v of the carriage of a typewritmg machine shall be carried by the platen and which shall overlie the lower edgeof the card so that the writingon the card may be performed without any danger of interference from any part of the-mech ani-sm..

This card holding strip is of curved in accordance with the contour of the platen and is deta'chably held at its ends for ready removal. On the inner side ofthe strip are provided a plurality of springs in the form of flat metal members fastened to springstend to'force the card holding plate edge of the strip than the otherand. the re .s sult of their action together with that of the the card holding plate at one end and having the other end freei The free ends of these away from the platen, Two or more of the springs are preferably located to extend longitudinallyof the platen while the other is placed near one edge and extends circumferentially of theplaten. The two longitudi- I [tion ofthe carriage having mounted na-l springs are preferably placed nearer one circumferentially extending spring is to cause one edge oftheholding plate to be spaced from the platen sufficiently to permit theready insertion of the'l'ower edge of the card. lVhenjinse-rted, the longitudinally extending springs form stops fonthe inserted edge while the circumferentially extending spring which is preferably located. at the left hand; side forms a stop for positioning the left hand edge of the card so that one card afteran'oth'er can be inserted for'w-riting and the writing wil-l' a-lw ays occupy the I I I I is a small plate 1 which may be fastened by screws 2 or in any suitable manner and is same relative position .on thecards.

extreme top edge thereof, and when the other limit is reached for thepurpose of removing the card and inserting anew one, the'il-ower edge o'f thecard holding strip will not pass above theedge of the card scales usually carried by the carriage. i

Further features of. theinventi'on will be apparent from the following detailed description and set forth. in the appended claims. I I

i There isil-lustrated in the drawings a portherein in'wthe usual manner a platen B havingan axle Z2; and against which bear the usual rear and front feed rolls G and D.

Royal machine; These parts, however, may

be varied widely in construction without afjfecting the scope of 'theinvention so that the l r tion is not to beregarded as' limiting the invention. v v

, .Attached'to the are hand endof' the platen end of the" platen but allow it to oscillate v V 70 Figure 2 is a perspective view of the card I slightly. At one side a springfiis contained in a hole 7 in the head of the platenand bears against the plate 1, thus forcing it outwardlyat'this edge. The opposite edge has a cutout or hole- 8. similar to the hole 3 in the plate 1 and also has a finger piece bent outwardly therefrom.

The card holding plate 10 of thin sheet metal has an ear 11 ateach end near the lower edge and this ear is shaped so that it will fit into the opening 8 or the opening 3 respectively. When the plate is in position and it is desired to remove the same, the pressure of the finger piece 9'will rock the plate 4 against the tension of the spring 6 and disengage this plate from the lug or projection =11 on the card holding member 10. The card holding plate can then be lifted and turns about the engagement of the lug 11 with the opening 3 in the plate 1 as about a pivot until .it reaches a position such that it may be readily disengaged from said opening. Then it is again desired to replace theplate, the opposite sequence of actions is followed. d

On the inside of the card holding plate are provided two flat spring members 12 which are soldered, riveted or otherwise fastened at one end to the plate and the opposite end of each member tends to swing outwardly as indicated in Figure 2. A similar spring member 13 isplaced near the left hand edge and extends circumferentially of the platen. Itsfree end also tends to'spring outwardly. Since the engagement of the lugs 11 with the plates 1 aud t in effect provides: a pivotal; mounting-for said plate at one edge thereof, it is obvious that the front edge of the plate will be forced outwardly from the :platen to an extent sufficient to permit the ready insertion of the card from v this edge. The lower edge of the plate, howof the platen or'carriage.

.. ever,-will engage firmly with-the platen and 'preventanyinterference between this edge of the-plate and any of the other accessories The springs 12 and13 also act as positioning members for the oardwhen inserted, since the springs 12 determine the position of the lower edge of the card and provide means whereby it will be positionedin the properrelation to the printing line while the spring 13, provides 'a left'hand edge guide for the card. If desired, the card holding plate 10 may be provided on its outer edge with an indicating ,line 1 1 denotingthe position of the inner edge of the spring-13 so, that the'user may readily place the card in the desired position.

The handle 15, is attached by a set screw 16 to the platen axle b and the hub of this I handle is provided with two arms 17 and .18. These arms coact with a screw 19 which A has an eccentric head for the purpose of determining the extent of rotation of the from the platen.

platenwhen being used for the purpose of writing cards. The eccentrlc screw -19 will be so adjusted that when the parts are in the Figure 5 position, theextreme upper edge of the card willbe in position to be written upon as shown by the type bar F in this figure. hen the arm 18 contacts with the screw 19, the platen will have been moved to a-posit-ion in which the card can be readily removed and another card inserted. It willbe noted that at this, time the lower edge of the card holding plate has not moved upwardly far enough to in terfere with the ribbon vibrator, card holding scales or other attachments of the platen.

It will be apparent that the handle 15 may be readily removed when it is not desired to use the same and that the card holding plate 10 may also be removed very quickly and easily. :A machine can, therefore, be

equipped for use with this plate for the purpose of writing cards without destroying its eliiciency for use as a usual typewriting ma chine whenever it is desired'to use the same for this purpose. Obviously various detail changes may be made in the precise construction of the invention without departing from the spirit, thereof, so that the invention is to be regarded as limited only by the scope of the appended claims.

I claim as my inventionz 1. A card holding attachment for a platen comprising a plate curved similarly to the curvature of the platen,'means at each end or the plate for attaching the same to the platen, and a plurality of flat springs attached to the inside of the plate and engaging the platen.
