CARD AND STENCIL HOLDER FOR TYPENRITING- IVIACHINES.

Application filed May 22,

The main objects of this invention are to provide an improved form of holder for use on typewriting machines for holding cards or stencils in. flat form in tangential relation to the platen. to receive impressions from the type keys; to provide a holder this kind vwhich may be readily attached to and removed from a typewriter of standard make, to provide improved line spacing means whereby the card may be moved. to dillerent elevations relative tothe holder to present dill'erent portions thereof to the type-bars; to provide improved line syncing means which is controlled in its operation by the rotation of the typewriter platen; to provide improved means for depositing carbon on the back of the stencil blank in areas corresponding to the areas of the type so that impressions on the stencil tissue will be visible; to provide a device of this hint wherein the iarbo-n depositing means will be fed simultaneously with the card during the line spacing operation; and to provide an improved typewriter attachment of this kind which will permit a card or stencil to be easily and quickly inserted and removed.

An illustrative embodin'ient of this invention is shown in. the accompanying drawing, wherein:

Figure 1 is a front elevation of an improved holder attached to a platen carriage which is shown only in part, a stencil supported in the holder being also shown.

Fig. 2 is a transverse section of the same taken on the line 22 of Fig. 1.

In the specific form shown, the improved holder is attached to the platen carriage and arr: nged so as to hold the card or stencil in an upright position directly in front of the platen where the writing may be visible to the operator. A holder embodying this invention may also be applied to other forms of typewriting machines. The holder includes improved manually releasable gripping devices which frictionally hold the card inv tangential relation to the platen roller and which also serve as line spacing means for raising the upright card step-bystep upon the rotation of the platen.

As herein illustrated, the holder is applied to a typewriter having the usual stationary frame 1 in which is pivoted a set of type bars 2 adapted for movement toward and from a platen roller 3 iournaled in a carriage t which is slidably mounted in the up- 1926. Serial No. .110,921.

per part of the frame. Suitable mechanism is provided for moving the platen carriage from right to left in a step-by-stcp movc- .ment upon the depression of the usual keys. Arrangedv in the frame 1, is the usual supporting block 5 on. which is mounted. the type bar guide 6. Inasmuch the u'esent invention relates to the holder, parts of the typewriting machine which. are believed unnecessary to a complete understamling of the invention have been omitted from thedrawing.

In the specific form shown, the improved holder comprises a supporting rod 7, on which is mounted a fixed backrest S and a pair of pivoted brackets 9, in which are journaled gripping devices resiliently urged into position for holding a card or.

in Fi 2 to )rovidc a iair oi u istandin t"? 3'71 hook-shaped lugs and a depending flange 16 which is disposed so to hold the stencil 11 against tilting under the action of the gripping elements carried by the brackets 9. The rest 8 is rigidly secured to the support 7 by screws 17.

in the construction illustrated, the brackets 9 are in the form of hell crank levers pivotally mounted on the rod 7 and secured agaiiiist axial shitting by screws .18 engaging peripheral grooves, not shown. in. the rod 7. lovers 9 extend rearwardly of the rod 7 and. are connected together by arod 19. Acting between the rod 19 and the lugs 15, is a pair of springs 20 arranged to normally urge the gripping devices 10 into frictional engagement with the stencil 11 and platen roller 8.

The gripping devices 10 are journaled in the depending arms of the bell crank lovers 9 and include knurled roller parts 21 and 22 arranged to frictionally engage the stencil frame and roller platen respectively. A portion of each bracket 9 is cut away. as shown at 23., to permit a slight. twisting of the depending arms of the brackets to com- The upper arms of the bellcranlr pensate for the thickness of the stencil and permit the rollers 22 to firmly engage the platen. The rollers 21 hold the stencil or card in tangential relation to the platen and, when the platen is rotated, the rollers 22 riding upon the platen cause the rollers 21 to rotate so as to feed the card vertically to present different portions thereof to the type 2 for impressing different lines.

in order that the impressions on the stencil blank may be visible, a carbon sheet 2 passes around the platen roller 3 and is held in frictional contact therewith by a roller 25 journaled at one end in a bell crank lever bracket 26, and at the other end in a lever 26.1 pivoted on the shaft 7 The roller 25 is normally urged into frictional contact with the carbon sheet by means of a spring 2'7 embracing the rod 7, so that, upon rota tion of the platen, the carbon sheet is fed along to present a fresh portion thereof to the stencil. The upper arm of the lever 26 forms a handle to permit the roller 25 to be manually released.

The yoke 12, which is adapted to release the gripping devices 10, is pivoted on the rod 7 and is secured against axial shifting by collars 28 fixed on the rod. The yoke 12 extends across the rearwardly projecting arms of the bell crank levers that, upon the depression thereof, the gripping devices are moved outwardly against the action of the springs 20. Suitable handle parts 29 are formed adjacent the ends of the yoke 12.

In operation, to insert a card or stencil into the improved holder, the handle parts 29 are depressed so as to move the rollers 21 outwardly, thereby permitting the card to be dropped between the guide 6 and the back rest 8, where it is supported in anupright position on the stationary block 5. The gripping devices 10 are then released so as to firmly hold the. card. To shift the card for line spacing, it is necessary to merely rotate the platen which thereby elevates the card to the desired position, through the friction of the platen surface and the rollers 21. lv'ith this in'iproved construction, when the card is shifted edgewise for line spacing, upon rotation of the platen, the carbon sheet is simultaneously fed edgewise so as to present a fresh portion thereof to the printing area. The carbon sheet feeds with the platen because of the pressure exerted thereon by the roller and also by the card or stencil. To remove the card, the yoke 12 is again depressed with one hand, whereupon the card may be lifted out of the holder with the other hand.

Although but one specific embodiment of this invention has been herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.

We claim:

1. A card holder comprising a support for attachment to the carriage of a roller platen, a pair of bell crank levers pivoted on said support and spaced apart from each other, a back rest fixed on said. support and located between said levers, gripping elements journaled on said levers for holding a card. against said back rest in proximity to the platen, a spring acting between said back rest and elements for normally urging the latter into operative position, said friction elements having parts for frictionally engaging the card and platen respectively whereby said elements and platen are operable upon the rotation of the platen to feed the card edgewise, and a releasing member pivoted on said support in position to engage said bell crank levers for moving said friction parts away from the platen and card.

2. The combination with a roller platen having a carbon sheet passing over its surface, of a card holder comprising a supporting rod mounted on the platen carriage, a bracket pivotally mounted on said rod, means on said bracket for holding a. card in frictional contact with the carbon sheet and operable with the platen upon the rotation of the platen for feeding the card edgewise, a second bracket pivoted on said rod, and a roller journaled on said second bracket and arranged to directly engage the carbon sheet to normally hold the carbon sheet in frictional engagement with the platen.

Signed at Chicago this 18th day of May, 1926.
