ASSIGNOB TO ROYAL TYPE'WRITER COM- PANY, INC., OF NEW YORK, N. Y., CORPORATION OF NEW YORK.

TYPEWRITING MACHINE.

Application filed` June 11, 1925. serial No. 36,370.

To all 'whom it may concern: f

Be it known that I, EDWARD B. Hass, a citizen of the United States, and resident of New York, in the county and State of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

The invention herein disclosed relates to card guides of a type similar in some re- V spects to those'previously employed in the usual Royal machines. The invention is disclosed as embodied in the Little Royal, although it is not limited thereto.

The purpose of the invention is to provide a. card holding guide which is particularly adaptedfor a compact portable machine and will hold a card or other sheet of paper firmly against the platen adjacent the printing point even when writing at the extreme side of the paper.

A further object of the invention is to provide the card guide with holding fingers, one of which is movable and is retained in operative and inoperative positions by the peculiar structure of the finger and guide itself without the necessity of any separate holding means.

Other objects of the invention will be apparent from the following detail description and the appended claims.

In the drawings Figure l is a front view of so much of a typewriter machine as is necessary to illustrate the invention and its relation to the other parts of the machine.

Figure 2 is a front to rear section through the machine with parts in elevation.

Figure 3 is a detail view of a portion of the card guide and movable finger on an enlarged scale and showing in dotted lines the nger moved to inoperative position.

Figure 4 is a section on the line 4 4 of Figure 3. l

The drawings disclose portions of a typewriting machine frame A, a key lever B, carriage C, platen D, type bar E, the usual roll holding bail F, carried by arms f which are pivotally mounted in the side frames of the carriage, ribbon spool casings j Gr, encasing ribbon spools II,a'ribbon vibrator and type bar guide K, and a ribbon'vibrator L. These and other parts which are illustrated form in and of themselves no part of the invention and may be varied within wide limits without affecting theinvention.

A card holding scale l is carried by arms 2 which are pivoted to the shift frame by screws 2 which pass through elongated slots l', thereby permitting verticali adjustment of the cardholding scale.' yThis permits the scale to be adjusted if necessary to bring kthe edge thereof in exact registry with the bottom of the line being printed. The scale has the usual cut-out 4 forming an opening through which the type bars-pass in their printing movement. Anv upwardly projecting holding finger 5 is 'located` adf jacent the right hand side of the opening 4.

A movable finger 6 is pivotally attached to the left hand side of the scale member l. Both'of these fingers are of general triangular shape and are curved in conformity with the curvature of the platen. The extreme edges of the scale plate l are curved forwardly as indicated at .3 and '3'. This prevents the edge of the scale platefrom catching Von the edge of a card when the carriage is moved back and forth across the machine. This curved edge 3 also has an additional function which will be hereinafter set forth.

The left hand finger 6 is pivoted by a rivet 7 or similar fastening member to the scalepplate 1,y a washer4 8 being disposed between the head of the rivet and the linger 6. The left hand side of this finger extends somewhat below the pivot point and the curved edge 10 of this downwardly extending portion nests with the curved portion 3 of the vscale plate as is clearly shown in Figure 4. For convenience, the finger piece ing 'the vfinger inits normal operative position. lWhen, however, the finger is moved downward to the dotted line position of Figure 3, the edge ll of said finger which is curved similar to the edge l() will then be moved to a position in which it nests with the curved edge 5 of the scale plate and thus the finger will be retained in its operative position. it thus appears that the iinger is retained in either of its positions by the construction of the finger and plate and without the necessity of providing any additional detent or holding means.

Since the finger 6 is curved in the direction of the platen it would appear that a rotation of the same about its pivot 7 would cause the eXtreme tip of the finger to contact with the platen and thereby interfere with such movement. This would be the case if it were not for the fact that when the body of the finger 6 rides over the curved edge 3 of the scale plate it is thereby moved away from the platen sufiiciently to prevent the tip of the finger from contacting with the platen during such movement.

By positioning the fixed finger 5 immediately adjacent the right hand edge of the opening 4 it is possible to hold the card or paper more firmly in proper position when writing to the extreme right hand edge thereof. lt is also to be noted that when the movable finger 6 is swung to inoperative position that the upper edge of the scale plate l becomes visible so that the scale graduations can be seen for a greater extent. Further when this ngcr is moved to inoperative position there is an uninterrupted view of the whole of the line already written.

rlhe invention therefore comprises a card holding scale plate provided with a fixed and a movable finger, all of said parts being so related as to produce a construction extremely efficient and welladapted for a compact portable machine. lt is obvious that various detail changes may be made without in any manner departing from the spirit of the invention which is to be regarded as limited only by the scope of the appended claims.

l claim:

l. A card guide comprising a scale member having a central opening to permit the passage of the type bars to the printing point, an integral rigid finger immediately adjacent the type opening, and a movable finger at the eXtreme end of the scale.

2. A card guide comprising a scale member having a central opening to permitl the passage of the type bars to the printing point, an integral rigid finger immediately adjacent the right hand side of the type opening, and a movable finger at the extreme left hand end of the scale.

. 3. A card guide comprising a scale member having a central opening to permit the passage of the type bars to the printing point, an integral rigid finger immediately adjacent the type opening, a movable finger at the extreme end of the scale, and means permitting vertical adjustment of the scale.

et. A card guide comprising a scale member having a flanged edge, and a movable finger pivoted thereto and having flanged edges, thev respective flanges of the finger nesting with the flanged edge of the scale to hold the finger in operative or inoperative position against displacement.

A card guide comprising a scale member having a curved edge, and a movable finger pivoted thereto and having similarly curved edges, part of one curved edge of the paper finger interfitting with the curved edge of the scale to hold the finger in operative position, and the other curved edge of the paper finger interfitting with the same curved edge of the scale to hold the finger in inoperative position.

6. A card guide comprising a scale member having a curved edge and movable paper finger pivoted thereto and curved to conform with the curvature of the platen, the curved edge of the paper scale acting to cam the finger to a position wherein it will not engage the platen during movement of said finger to and from inopera' tive position.

7. A card guide comprising a scale member having a curved edge, and a movable paper finger pivoted thereto adjacent said edge and curved to conform with the curvature of the platen, the curved edge of the scale having three functions; to prevent catching the edge of a cardv as the platen moves across the machine, to nest with the paper finger to hold it against accidental displacement for either of its positions, and to cam the finger to a position wherein it will not engage the platen during the movement of said finger to and from inoperative position.

8. A card guide comprising a scale mem- -ber having a central opening to permit the passage of the type bars to the printing point and having both ends curved away from the platen, an integral rigid finger immediately adjacent the right hand side of the opening and a movable finger at the extreme rleft hand end of the scale, both of said fingers having flanged edges and bot-h being curved to conform with the curvature of the platen.

9. A paper or card guide associated with a platen having case shift movement and comprising a rigid finger immediately adjacent the. printing point, a movable finger at one extreme end of the guide, and a support for said fingers which shifts in unison with the case shift movement of the platen.

10. A paper or card guide having two flanged edges and both being arranged to extreme out-turned ends and an upwardly deflect the paper to the rear of the printing extending paper nger closely adjacent to point. 10
