EDWARD B. HESS, OF NEW YORK, N. Y., ASSIGNOR T0 ROYAL TYPEWRITER COMPANY, INC., OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

TYPEWRI'IING MACHINE.

Application filed September 25, 1925.

.l '0 all whom it may concern Be it known that I, EDWARD B. Hnss, 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 to that shown in my copending application Serial No.

36,370, filed June 11, 1925, and is in some respects an improvement on -the construction shown in said prior application. lVhile the invention is primarily designed to be used in connection with a compact portable machine, such as the Little Royal and is especially adapted for use with such machine, nevertheless it is in no way limited in its application to this particular type of machine.

The invention provides a card guide which has an upper graduated edge adapted to register with the printing line and which is provided with two card holding fingers one of which is rigid with the guide and the other of which is movable from a position in which it extends across the printing line to a position in which one edge thereof forms a continuation of the graduated edge of the card guide. The guide is mounted on its support by means which permit both vertical and lateral adjustment thereof.

In the drawings:

Figure 1 is a front view of a portion of the platen disclosing the card guide forming the subject of the invention in its relation to the platen and its support.

Figure 2 is a similar view in'which the movable finger has been moved to a position in which its edge forms a continuation of the scale edge of the card guide, and affording complete range of visibility.

Figure 3 is a section on the line 33 of Figure 1.

It is unnecessary for the purpose of this invention to disclose any appreciable portion of the structure of the typewriting machine. There is therefore only illustrated a portion of the support A which it is to be understood is carried by the shift frame so that it changes position when the platen B is shifted but is stationary relative to the longitudinal movement of the platen.

Serial No. 58,548.

The card guide 1 has two depending leg portions 2 each provided with a slot 3 which as indicated at 4 is wider than the stem of the holding screw 5 whereby provision is made for both lateral and vertical adjustments of the car-d guide. The verticalan d lateral adjustment is to bring the upper edge of thes guide into exact registration with the printing line; the lateral adjustment serves also the purpose of locating an indicating projection 6 in exact registry with scale graduations on a scaleC, carried by the platen carriage and indicating the printing point.

The card guide has the usual central out out 7 adjacent which and at the right side thereof is a rigid finger 8 curve-d in conformity with the curvature of the platen and having outwardly related edges 9 terminating in a cylindrical portion 21 which prevent the fingers from catching the edge of paper or cards held thereby during the relative lateral movement of the platen and card guide. At substantially the extremeleft hand edgev of the card guide and at a point widely removed from the cut out 7 is a movable paper finger 10 which is held by'a pivot in the form of the rivet 11 cooperating with a spring washer 12. This permits the finger to be held firmly in position and at the same time allows it to be turned freely when desired. This paper finger is also curved in conformity to the curvature of the platen and has rolled edgesl3 while theiextreme end portion is a general cylindrical form to form a finger piece 14 for the manipulation, of the paper finger. The lower and inner portion of the finger 10 has two shoulders 15 and 16 which cooperate with a pin 17 carried .by the card guide to limit its movement to each of its operative positions. The right hand edge or inner edge of the finger 10 is graduated with the usual scale graduations and when the finger is moved to a position in which the shoulder 15 contacts with the pin 17 this edge18 Will form a continuation of the graduated edge of the card guide 1, as shown in Figure 2.

Both extreme edges of the card guide are rolled outwardly as at 19 and 20 but the portion of the edge 19 over whichthe finger 10 moves when passing from one position to the other is cut away or of a less height than the rolled edge 20 in order that it may as certain features of the invention are concerned it might be formed in two parts separated by an opening corresponding in position and function to the cut out 7. It is also apparent that if desired both paper holding fingers might be made movable instead of having one movable finger and one rigid. Other obvious detail changes will fall within the spirit of the invention which is to be regarded as limited only by the scope of the appended claims.

I claim:

1. A card guide comprising a scale member having a central opening to permitthe 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 for stopping said finger in a position wherein it constitutes an extension of said scale.

2. 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 right. hand side of the type opening, a movable finger at the extreme left hand end of the scale, and means for stopping said finger in a position wherein it constitutes an extension of said scale.

ber 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, means for stopping said finger in a position wherein it constitutes an extension of said scale, and means permitting vertical and lateral adjustment of the scale.

4. A card guide comprising a scale member, a inovbale finger adjacent one edge thereof, and means for stopping said finger in a position in which it. constitutes an ex tension of the scale member. s

i". A card guide comprising a scale memher, a movable finger adjacent one edge thereof, and means for stopping said finger in either of two positions in one of which it extends across the printing line and in the other of which it forms an extension of the scale.

6. A card guide comprising a scale member having graduations on its upper edge, a movable finger carried thereby and-haw ing graduations on one edge, and means for stopping said finger in a position in which it forms an extension of the scale member and its graduations form a continuation of the graduations of the said scale.

7. A card guide comprising a scale member, a movable finger adjacent one edge thereof, means for stopping said finger in either of two positions in one of which it extends across the printing line and in the other of which it forms an extension of the scale, and means permitting vertical and latral adj ustment of said scale.
