TYPEWRITING MACHINE.

Application filed May 13, 1922. erial No. 569,?07.

To all whom it my concern;

Be it known that I, WAIIIER D. CAMP, a citizen. of the United States, residing" at Wethersfield, in the county of Hartford and 5 State of Connecticut, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

This invention relates to the paper supporting and guiding tables of typewriting machines-in which a gage and an associated scale are provided at one end of the table to definitely position the edge of the paper relatively to the printing point on the platen. Such gages and scales have heretofore been used in the Royal machines and are very serviceable in many classes of work. According to my invention the table is formed near one end, preferably the lefthand .end, with a depression in which a graduated scale plate is adj ustably mounted. narrow elongated opening is made through the depressed portion of the table at each end of which there is a transverse slot and ledges or flanges are formed above and below the narrow opening on which the scale plate rests, the opposite ends of the plate being passed through the slots at opposite ends of the opening and bearing against the rear side of the table. A. threaded stud, projecting rearwardly from the scale plate, extends through the elongated opening of the table and carries a clamping device by means of which the plate may be held in the desired adjusted position. I

The paper gage comprises a base portion which extends across the table from top to bottom over the scale and which is provided on one side with a flange disposed at right angles to the body. An observation opening is formed in the base and also in the flange by means of which the scale may be inspected and a pointer, formed on the base portion of the gage, projects into the opening over the scale. I

The lower edge portion of the body of the gage is turned downward to form a lip which rests on the lower edge of the table, while the upper portion of the gage is extended over the top of the table and is prolonged to form an arm, which extends downwardly below the top of the table its lower portion being made to engage a horizontally arranged rod which extends across the machine in rear of the table.

In order to secure the gage to the supporting rod T employ a clamping device which engages the rod and which is attached to the arm of the gage by suitable devices. The clamp is formed with an arm or fin er which extends to the rear side of the ta' lo and bears against it in such manner as to hold the gage on its supporting rod yieldingly in order that it may not be moved accidentally but may be adjusted when desired.

The table has a smooth unbroken top over which the paper passes and it is. carried by supportin arms which are attached to downwar y extending flanges'of the table so that no fastening devices'appear on the supporting arm? before referred to which extends over the top of the table and by'the hp at its lower edge portion which en' ages the table at its extreme lower end.- ther' features of the invention will be hereinafter describedg'.

In the accompanying drawings':

Figure 1 is a side elevation of parts of a Royal typewriting machine with my improvements applied, some parts being shown in section for clearness of illustration and the raised position of the table being indicated by dotted lines.

Figure 2 is a view on an enlarged scale of some of the mechanism illustrated in Figure 1.

Figure 3 is a perspective View of the table and parts carried thereby detached from the carriage frame.

Figure 4 is a view on an enlarged scale and in section illustrating ortions of the mechanism in rear of the ta lo, the section being taken on the line it of Figure 2.

Figure 5 is a perspective view of the clamping device employed for connecting the gage with its supporting rod;

Figure 6 is a perspective view of a portion of the table illustratin clearly the depressed portion thereof an the elongated opening and slots in the depressed part of the table.

Portions of the side plates of the carriage frame are indicated at A, and B indicates a platen. C represents a type bar guide, D a'margin stop rail and E a tabular rail. The top paper guide roll supporting arms F and the lower paper feed rolls G as shown are of the usual Royal construction. The paper an H extends under the platen and upwar ly in rear thereof in the usual way and is supported at the rear by a frame iece I which carries a strip or pad J of fe t or similar soft material which serves as a cushionfor the table when swung from its raised position to vgorking'position over the paper pan. The paper table K is formed with upper and lower curled or beaded edge portions It, It and at its opposite sides with downwardl-y extending flanges k to which the table so ports or arms K are secured. These ta is supporting arms are pivotally mounted to move about the longitudinal axis of, the

serve to support the scale tabular'rail and they are equipped with springs e which serve to hold the table in either forward or rearward position as here-- tofore. When in operative position, the table is held against the pad J and should it tend to vibrate, no noise is produced.

The table as thus constructed and mounted presents a smooth, attractive surface for supporting the paper and is free from the presence of the screws or securing devices heretofore employed. It will be observed that the upper and lower portions of the table are smooth and unbroken and not cut away as heretofore.

The table is formed with a depression L preferably at its left-hand end portion, although it may be thus formed at the righthand end or at both ends if desired. This depression is of such size as to accommodate a scale plate M graduated to correspond with the other letter ace scales of the machine, being somewhat onger than, the depressed portion of the table as indicated. This depressed part of the table is formed with a narrow elongated opening Z which connects at its opposite ends with slots Z, Z which are somewhat longer than the width of the o ning Z and extend to the upperand lower e ges of the depressed portion of the table. In this way, ledges Z are produced which plate when it is inserted in the manner indicated in Figure 3, where it will be observed the opposite end portions of the scale are passed through the slots Z, Z and bear against the rear face of the table, while the middle ortion of the plate rests on the ledges. he scale plate carries a threaded stud m which extends through the opening Z and carries a washer m and a clamping nut m By these devices, the scale plate'may be readily adjustmesses formed with a flange n disposed at right angles to the body. The gage extends across the scale and is formed in adjacent parts of the body and the flan e with an observation opening :1: through w ich the scale may be observed. The pointer N. formed integrally with the guide extends into the opening above the scale. The lower edge rtion of the gage is formed with a li or ownwardly extending part n whic bears on the lower beaded ed e or the table as indicated most clearly in igure 2. The upper part of the gage is bent over the top or upper edge of the table and is formedwith an arm U which extends downwardly behind the table and is formed with a concave lower portion 0 engaging a horizontally arranged rod P supported in the table arms K. I

In order to secure the gage to the support ing rod P I employ a clamp Q cave portion 9' fitting the rod P and an upper part 9' havin a central opening 1* to receive a short bolt carrying a nut r The upper part of the clamp is formed with a lip 1' which serves to prevent the nut from turning on the bolt when the clamp is being applied and subsequently. The lower part of the clamp is formed with an arm or finger S which extends forwardly and bears against the table yieldingly. By these devices the upper portion of the gage is held away from or out of contact with the part of the table while the lower part 0 the gage is held away from the table by the lip n the-edge of which bears on the beaded lower portion of the table. It will thus be seen that the gage is held away from that portion of the table which supports the paper so that the gage may be moved freely over the table which supports paper over which the gage is moved, and a right hand additional gage may be used where split billing is being done; there is no danger of injury to the paper table. The upper part of the gage may be so supported on the rod P that it may without loosening the clamping devices be moved crosswise of the machine to any desired extent and when once ad justed will be held friotionally in place without danger of being accidentally moved. it will be observed thatthe spring finger or arm S has a yielding sliding connection with the table and the bolt R may be so adjusted as to permit the gage to be readily moved sidewise. If desired, the bolt may be tightened to hold the gage securely in any position to which it may be adjusted.

By the devices shown, it is possible to ad just the gage definitely a given number of scale spaces corresponding with the letter having a conupper Elli naeaaee spaces on the machine, it being understood that the scale spacing of the scale plate M corresponds with the letter spaces on all other scales in the machine. The manner in which the gage is used may be understood from a single illustration. If the pointer N is located at zero and the margin stop on the machine is set at 20, it would indicate that there would be spaces from the edge of the sheet to be written upon to a point Where printing would begin and if it be desired to add five more letter spaces or to diminish the margin to that extent it would be unnecessary for the operator to adjust the margin stop, it being only necessary to adjust the paper gage five spaces to the right v and the printing would begin at that point.

, If the operator has a set or predetermined margin which is always adhered to in the usual width of paper, this relation can be assured and maintained at all times in case it is desired to move the gage to a position to the right to use paper narrower than the standard width and where a set margin is still desired.

The table and scale is so designed as to facilitate the removal of-the scale and the insertion of scales of different pitches. Instead of the factory having to make up a large stock of paper tables of difi'erent pitch scales, the scale corresponding to the pitch of the machine maybe inserted at the time of its being assembled in the machine. It will be observed that in the machine in which my invention is employed, the margin stops and the tabular stops are located behind the table. Access thereto may be obtained by raising the table, but it is not always desirable to thus raise the table and by utilizing the adjustable margin gage hereinbefore referred to suitable adjustments of the margin of the paper may be obtained without raising the table. The margin adjusting devices are in plain view and within easy reach of the operator. This feature of the invention broadly considered is, however, shown, described and claimed in an a plication of Edward B. Hess and Lewis Myers, No. 473,162, filed May 27, 1921. The subject matter hereinclaimed as my invention is set forth in the accompanying claims.
