JOHN PURDY, OF BROOKLYN, NEW YORK, ASSIGNOR TOTHE MONARC TYPEWRITER COMPANY, OF SYRACUSE, `NEW YORK, A CORPORATION yOF NEW YORK.

Be it lnoivn that I, JOHN PURDY, citizen of the United States, and resident of the borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in T vpe-lVriting Machines, of which the following is a specification.

My invention relates to typewriting machines and more particularly to gages for the side edge of the paper.

Une Object of my invention is to provide simple and eilicient means for effectivelyv gaging the Widthwise position of the paper with reference to the platen.

A further objectof my invention is to provide vsimple and efiicient means for readily effecting an adjustment of the 'gage throughout, or substantially throughout, the length of the platen.

still further object of my invention is to render the gage readily detachable from the machine when desired.

To the above and other ends which will hereinafter appear, my invention consists in the features of construct-ion, arrangement of parts and combinations lof devices to be hereinafter described and particularlyT pointed out inthe appended claims.

In the accompanying drawingsl wherein like reference characters indicate "coi-ref' spending parts in the various views. Figure .l is a detail fragmentary plan vieiv with parts broken away of a carriage of a [Monarch machine embodying my invention. Fig. 2 is a transverse'sectional View ofv t-he same. Fig. 3 is an enlarged detail transverse sectional View taken through the sup porting har for the gages at. one of -the points of connection between the supporting bar and paper table. Fig. 4 is an enlarge detail transverse sectional view taken through one of the supporting devices for the gages and through the supporting bar on which it is adjustably mounted.

l have shown in accompanying drawings only so much of the carriage of a Monarch machine as is necessary to illustrate my invention.

The carriage vof a Monarch machine comprises a rear cross or slide bar 1 and for- Wardiy projecting end bars 2. A platen shaft 3 extends through bearing o enings in the end bars 2 of the carriage and) supports a. rotative cylindrical plate-n 4. Finger Specicaton of Letters PatentA Application flied April 2o,

1909. Serial No. 491,035.

Wheels 5 are provided at the ends oijthe plat-en shaft for rotating the platen. 'The usual combined platen and carriage scale 6 is mounted on supports (not shown) to travel with the carriage. A paper table 7 is provided with depending bifurcated bracketsS which straddle the stems of headed .screws 9 which are supported in tapped openings in lugs 10 that project forwardly frointh/e slide har l of the carriage. The papertable is thus supported in place on the ..carriage. The paper table is apertured near pockets ll riveted at l2 to the paper table. These pockets are each adapted toreceive a pin or lug 13 riveted to and projecting from a supporting or rack bar 14 which extends throughout or substantially throughout the length of the paper table and platen and longitudinally of the paper table. The supporting bar is held on the frontface of the paper table near the topl edge thereof and close to the paper table as indicated in -Figs. 1 and 2. v ,The supporting bar 14 is provided Withj'indices 15 which correspond to the/inscale and are situated, with" reference to the length of the carriage, i the saine positions dices on the c rriage scale so that numeral 2O for instance on the carriage or platenv scale is in the same vertical plane as the corresponding numeral on the supporting bar 14. Oneedge ofthe supporting bar has interdental Vspaces I6; adjacent spaces being situated a letter space distance apart. A locking part 17 is mount ed at one end of a spindle 18 received in a slide or supporting device 19 andfproyided with a linger piece or head 20. i chamber 2l isformed in the supporting device 19 to receive a coiled spring 22 which surroundsthe spindle 1.8 'and bears at one end against/an end Wall of the chamber and at the other end against the hub of the finger piece 20. Pressure of the spring 22 is thus exerted to movel 'the locking head into one of the tooth spaces 16 to secure the device 19 in the position to whichfit is adjusted along the supporting loar 14. There are two of these devices 19,. one situated ordinarily near the leftrhand end of the'supporting bar andthe other the right-hand end portion thereof.' The ga 623 that-fis curved face a sideedge4 apex' d) lyas indicated in l forwardly and ownwa the upper edge thereof to receive sockets or dices' onjthe combined platen and carriage neairi i F-ig. 2 to lcontorni generally to the curvature of the paper table so that the gage may be 5 right angles to the length of the t-able and to the axisof the platen so as to present a con'- tact face for coperation with ripide edge ot "thesheet4 The right-hand side edge gage'24 is'likeivise supported on the inner face of its ,v10-companionsupporting de-vice 19. By this construction each of the side edge gages may be adjusted( throughout' or substantially throughout the length of the paper table and the platen or to any letter-space positionthroughout the length of the platen in order to coperate with sheets ot any Width at any point lengthwise of the platen.

As the sheets are introduced into themachine they are placed over the supporting bar 14 between the

gages

23 and 24, the side edges of the paper being brought into contact with and squared against the side edge gages (or either one oit them) and the paper is thus accurately directed to the platen at any position in the length thereof determinedv by the setting of the gages. The indices on the supporting bar licorresponding to those on the carriage or platen scale enable the gages to be readily set to the desired positions Without experiment.

While I have described the use of two paper gages 23 and 24, it should be understood that in some instances the employment of a single gage is sutiicient.

If desired the Supporting bar With the gages thereon may at any time be readily removed by withdrawing the pins 13 from the sockets 1l in which they are received.

`What I claiml as nevi7 and desire to secure by Letters Patent,- is
