CARD-GUIDE FOE TYPE-WRITING MACHINES.

Application filed November 27, 1915.

To all whom it may concern:

Be it known that l. Yum-1n N. Diucw, a

citizen of the l'ni'ted States'of America. residing in Vatertown. in the county of Middlesex and State of Massachusetts. have invented certain new and useful Improvements in Card-Guides for Type-\Vriting Machines, of which the following is a specification.

This invention relates to card guides for typewriting machines and has for its object to provide a transparent card and paper guide that will adequately hold cards and paper against the platen in the vicinity of the action of the printing devices or type. The invention belongs to that class of card and paper holders or guides located at the central'part of the machine which comprises a guide plate held stationary relative to the transverse traverse of the carriage with its upper edge,which may be provided with a scale, adjacent to and just below the l ne of print.

Heretofore such guide plates have. been provided with upwardly arranged guide devices, as fingers, extending across the line of print and located adjacent the pointofprint at one or both sides thereof, the arrangement being such that the characters, as printed, are visible and exposed in the printed line for some distance to the left of the printing point.

It often happens in the use of machines having guides of this character that the upper edge or parts of cards, particularly stiff cards, bulge forward above the scale plate and become marked or smeared by the. ink ribbon as it moves in front of the operating type and it is to eliminate this objectionable feature in the typewriting of cards, without in any way obstructing the view of the, matter being printed, that this transparent card guide and guard has been devised.

The invention is illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of that part of a Royal typewriting machine to which this invention is applied.

of the carriage. The side frames (3 support the rotating platen T and below the platen are shown a paper pan 8 and pressure rollers 5) and H). all of usual construction. In Fig. 1 is shown upper glide rollers 11, ribbon vibrator 12 in lower osition and type bar 13 in printing position.

The eard guide and guard is held stationary relative to the feeding movements of the carriage and platen, it being secured to the rail 4 of the carriage shift frame by means of the guide supports 14 which are fastened at their lower parts to said rail and extend there From forwardly and upwardly in front of the laten to a s iort distance below the printing line. as indeated in Fig. 3. To the upper ends of the uide supports 14 is secured. by means of screws or screw studs 15, a guide plate 16 that extends a short distance at each side of the printing: point with its straight upper edge located ]\1Sl; below the line. of print. said edge being marked with an indicating scale is shown. The ends of this guide plate are bent ordairved forwardly as shown at 17.

The. parts so far lescribed are similar to corresponding parts at present in use on the said Royal machine. The gist or essential feature of this invention is in the construction and applieatioi' of a guide for holding cards, etc... against or toward the platen above the line of pri at and for fully protecting or guarding the same from interference by any of the movii g parts of themachine. To accomplish this object. and at the same time leave the vision free to examine the full line of printing as the characters are in1- pressed on the can. or paper between the.

guide and platen. said guide 18 is composed of a thin sheet or pi ce of transparent material which ma v be celluloid or other suitable material. This transparent guide 18 is curved toward the platen. as shown at Fig. 3. In the. transparer t guide are forrred holes 19. Fig. 2. which set over the screws or screw studs 1:) of the guide supports whereby it is held in operative position. This transparent guide is providyd with a central opening 20 which alines with an opening in the guide platelfi. as shown at Fig. 2, for thepassage of sion. as shown at F5 g. 1.

It will be observed that the guard 18 is of such size that it e: tends to a considerable extent or esi=i( d the printing point and the type .vhen making an impresthat the two parts of the guide are connected as indicated at 21 above the opening. In this way the guide is made strong and rigid and an unbroken upper edge is provided,

thus avoiding the presenceof points or angles which might 'be engaged by'the cards.

It will also be observed that the guide 18 is' secured to the scaled guide 16 and that when the guide 16 is attached to the rail 4 the transparent guide which it carries is prop- .erly located. I

I claim: 1. A card guide for typewriting machines comprising a fixed horizontally arranged plate having its upper edge disposed below the line of print, and a transparent card guide rigidly attached to said plate having an unbroken upper edge and foruu-d with an opening through which the type pass to the printing point.

2.. A transparent ea rd guide for typewriting machines having aide portions disposed on opposite sides of the printing point, a-

lniddle portion which rigid! connects said side portions, and an opening for the pas-- sage of the type in combination with means for supporting said guide in operative positlon. g
