CARD-'HOLDERFOR TYPE-WRITING MACHINES.

Specification of Letters-Patent.

' Patented May 20. 191-9.

To all whom it may concern.

Be itkn-own that I, CARL GABRIELsoN, a citizen of the United States, and resident of Syracuse, county of. Onondaga, State of New York, have invented certain new and-useful Improvements: in Gard-Holders for Type- Writing Machines, of which the following is a specification.

This invention relates to improvements in card holdin and feeding devices for typewritingmac ines, and is especially designed for the making'of stencil cards. The object of the invention is to provide means for securely holding the card and feeding the same tangentially to the platen of the typewriter without bending. or mutilating the card. The various novel features of the invention will be described in the following specification, taken in connection with the accompanyingdrawing, in which:

Figure 1 is a front view of a tppewriter carriage with the card holding and feeding devices attachedyparts being. broken away and parts omitted which do not pertain to the present invention.

Fig. 8 is an edge view of thesame. I

Referring to the drawing, 10 indicates the usual platen shaft and 11 a platen thereon. The platen is shorter than is customary for ordinary writing and is preferably but slightly longer than the. cards to be writtenupon. It may have a hard rubberor composition surface and be cylindrical, as usual,

although a. segmental platen would sufiice, as only a portion of its surface is necessarily utilized. To insure a perfect cuttingxof stencils, and for the purpose ofproviding a writing surface for the platen which may be renewed when worn, I- attach to. the platen two longitudinally arranged clips 12, 13 by- The screws or other suitableffastenings. forward edges of these clips are undercut to provide recesses at 14 into whichthe edges of a plate 15 of celluloid or other suitable resilient and yieldable material may be sprung- This plate 15 will fit snugly to the platen and provide a suitable surface upon which to cut stencils by means of the usual typewriter. type. I provide. a tool, which; will be described herein, by means of which the surface plate 15 maybe quickly removed.

with the edges 19 bent up to form card guides and a portion 20'connecting1 their lower ends. The portion 20 has a flange 20 at its loweredge upon-whichthe card rests when inserted in the holder. also provided with lugs 21 which slide in guides22 which guides may be mounted on slides 23 similarto those which carry the marginal pressure rollers of the ordinary typewriter. The present invention willbe described as applied to a front striketype writing machine such as the-La C. Smith &

Bros. typewriter. The slides 23 are mounted on a bar 24-which1s fiXed on the .-paper carriage.

from the arms. 17 and 18 toprovide room for the cards betweenthem, arms 17,.18and plates 26 constituting inner-.an-d-outer-guideS,-' respectively and they have fingers 28 ex- The plate is.-

Thecard holder also comprises; twolight metal plates 26 situatedin frontzof v andparallel withthe arms 17 and l8'and" secured to the latter by rivets or other devices27. The plates 26 arev suitably. spaced tending upwardly and fingers 29 extending downwardly, whereby the ends of the cards are held against the arms 17 and 18. The upward ends of the arms 17 and 18 preferably flare rearwardly as shown at 17*, 18 and the upper ends of the fingers 28 are flared forwardly as at 28 to facilitate inserting the cards. The fingers 28 may have shoulders 28 to yieldingly hold the cards in position for printing.

On the arms 17, 18 of the card holder are lugs 30 which are provided with pins 31 en gaging radial slots 32- in radially arranged rigid arms 33 suitably secured to the platen shaft, as byscrews 34. The arms 33 are also adjustably secured to the ends of the platen by screws 35.

In Writing stencil cards it is o1ilynecessary to write a few lines and I therefore provide a stop for quickly locating the card at the proper position to write the upper line. I also preferably rovide a stop for preventing the writing 0 a line too low on the card. Th preferred form of stops is shown in Figs. 1 and 6, in which 40 indicates a segmental plate arranged upon the platen shaft adjacent to the usual line feed ratchet wheel 41. The plate 40 is provided with a slot 42 and is adjustably connected to the ratchet wheel by a screw 43 passing through the slot. The segmental plate 40 is also provided with upper and lower lugs 44 and 45.

The holding pawl or detent 46 for the ratchet wheel engages the teeth between these stops and the stops are'arranged to contact with the bearing 47 of the friction wheel which forms the holding pawl or detent 46.

It will be apparent that in operation the cards may be quickly inserted between the fingers 28 and the arms 17, 18 of the holder and as easily removed. The cards should be pressed into the holder until they rest against the ledge 20 at the lower edge thereof. Before writing vthe platen shaft is turned by means of the usual knob to bring the card holder to its lower position, which is determined by the stop lug 44 striking the bearing 47 (Fig. 6). The card is fed upward orwriting successive lines in the usual manner of operating a typewriter. As soon asthe writing is finished the card may be removed by simply pulling it upward out of th holder. The position of the first line on the card may be regulated by adjusting the stop plate 40 on the platen ratchet 41.

Among the advantages of my invention it will be noted that the cards are not bent or distorted in any way while being written. They lie against and tangent to the celluloid plate on the platen, belng tangent to the platen at the printing pointso that they are firmly backed whenstruck by the type. In order that the cards may com in contact with the platen surface the celluloid plate is slightly shorter than the distance between the arms 17, 18 of the holder so that the arms can lie against the platen surface. The celluloid plate and arms 17 18 are preferablyof about the same thickness so that the arms will not hold the card away from the celluloid surface.

Among other advantages, it will be seen that the cards are fed positively, and hence the lines on the cards will always be in the same relative .positions. The tangential movement of the card is in an upward and downward direction across the front face of the platen and is controlled by the fixed guides'22. Theslots 32 in the rigid arms 33 provide for the slight relative movement of the arms and the card holder due to the fact that the arms move ina circular path while the card holder moves in a plane.

The tool for removing and replacing the celluloid plates is shown in Fig. 7. This tool comprises a plate 50. which has at one side a tongue 51 having a hook 52. This hook can be inserted in the opening 16 in the upper clip 12 so as to engage the upper edge of the celluloid plate. On pulling the hook downward the plate will bebuckled and its upper edge drawn outv from under the clip, which permits the plate to be removed. The upper edge 53 of the tool '50 is straight and of nearly or quite the length of the celluloid plate. When it is desired to insert a new plate this edge ofthe tool is held in front of the lower edge of the upper clip 12 with the plane of the'tool extending about radial to the platen. A celluloid plate, which is flexible, is pressed into the recess in the lower clip. The plate is bent or bowed and its upper edge presseddown into theangle between the tool 50 and the platen. The tool is then tipped forward and withdrawn, the upper edge of the celluloid plate springing into a recess in the upper clip. If the celluloid plates are out just wide enough to fit between the'clips, theywill spring into close contact with the platen and furnish a solid writing surface.

Having described my invention, what I claim' and desire to secure by LettersPatcut is: V a
