guides, table and feeding rollers for the paper, which are not described herein, as they formY no part of my present invention.

The illustrated construction of my linespacing means comprises the ratchet-ring 10, a pawl 19 eoacting with said ring, means for actuating the pavvl 19, and means for shielding 211 portion of the ratchet-ring from the aw `As best seen in Fig. 4, the pawl 19 is arranged at substantially a right angle to the end face of the platen 9 provided with the ratchet-ring 10, and is movable longitudinally toward and from said face, and also in a direction at an angle thereto. Y Thel means for actuating the pawl 19 oo nsists of a lever preferably having a uniform throw or movement, and forming a support or carrier for the pawl. lSaid lever or carrier comprises a barrel 20 in the bore of Which the pawl is guided, an upwardly-extending tinger-engaging arm 21, and a stud 22 projecting laterally from the barrel 2O intermediate of the ends thereof, at substantially a right angle to the axis of the platen. Suitable means, as a spring 23, indicated by dotted lines in Fig. 5, is arranged in the bore of the barrel 20 for moving the pavvl 19 end- Wise into engagement with the teeth of the ratchet-ring 10. Said stud 22 is here illustrated as journaled in a substantially cylindrical portion or forward extension 24 of one of the side bars 13 ot' the carriage 12, and as provided at its rear end with an annular groove 25 which receives any desirable means, as a screw 2U, for preventing detach- Vnient of the pawl-carrier from the part 211.

A spring 27 is coiled about the substantially cylindrical port-ion 24 of the carriage and has one end tixed to said carriage by the screw 26, and its other end detachably engaged with a lateralijf-extending shoulder 2S provided on the end of the barrel 20 nearestv the ratchet-ring 10. In the operation of the pawl-carrier, the. upper end of the arm 21 is engaged by thc linger and pressed outwardly, thus rocking upwardly the inner ends of the barrel 20 and the pawl 19 and advancing the'platen 9.

The means provided for shielding a portion of the toothed ring 1() from the pawl 19, operates to prevent the engagement of said pawl with one or more teeth in register therewith.during the first part of the vmovement of the pawl, and thus varies the effective throw or feed thereof. Said means preferably comprises a revoluble sleeve 29, arms 30. 31 jn-'ojecting radially from the ends ot' the, sleeve and rigid therewith, and means coat-.tingl with the arm 31. for moving` said arm vvariable distances and holding the same in its adjusted position. The sleeve 29 is mounted on the. shaft ll between one of the side bars 13 of the carriage and the end face of the platen provided wn'n the ring 10. The arms30, 31 swing with the sleeve 29 on the shaft 11, the free end of the arm 30 being movable in between the pawl 19 and the ring 10.

As here illustrated, Figs. 5 and 10, the means for moving the sleeve 29 and the

arms

30, 31 and holding the same in their adjusted position consists of a member movable revolubly and axially and comprising a stem 32 journaled in an arm 33 projecting upwardly from the side bar 13 provided with the cylindrical portion 24, a pinion 34 fixed on the inner end of the stem 32 and meshing with teeth on the free end of the arm 31, a hand-piece 35 on the outer end of the stem 32, and a stop-member, as a pin 3G, tixed to the stem 32 and coacting with a plurality of stop-members, as notches 3T, F ig. 4, in the inner face of the arm33. The end of the stem 32 provided with the handpiece 35 projects beyond the outer side of the arm a sufficient space. being interposed between opposing faces of the arm and the hand-piece 35 to receive a spring 3S which is coiled about the stem 32 and normally holds the stop-pin 36 in engagement with the walls of one of the notches 37. ln adjusting the position of the sleeve 29 and the

arms

30, 31, the hand-piece 35 is moved toward the arm against the aetion of the spring 38 a suilicient distance to carry the pin 35 out ofthe notch 37 formerly occupied thereby, whereupon the hand-piece is moved about its axis, and owing to the engagement of the pinion 34 with the arm 31, the parts 29. 30, 31 revolve bout the shaft 1l. Ai'li'ter the desired ad. v..tment of the arm 30, the hand-piece 35 is released and the vspring 33 moves the stem endwise and t'orees the stoppin 36 into one of the notches 3l.

' My invention may be equipped with any desirable means for preventing undue movement of the platen, hert` shown, Fig. 10, as a friction-roller 39 which engages the end face of the platen provided with the ring 10 and is carried by a plunger 40 guided in the arm 33 and forced toward the opposingv surface of the platen by a spring- 41.

The carriage of my typewriting machine is preferably provided with a rack-bar 42 which coaets with a suitable pinion 43 of the eseapemclit-mechanism for the carriage, and is formed with arms or rack-lifters 44 extending from front to rear of the carriage snl'istantially parallel to the axis of the pawlcarrier and pivoted intermediate of heir ends to the side bars 13 by pivots 45 extending substantially parallel to the platen 9. Said arms 44 are provided intermediate of their rear ends and the pivots #t5 with slots t6 for receivingr pins 47 projecting from the side bars 13. The front end of the left-hand bar .44 is provided with a thumb-piece 48 for facilitating' downward movement thereof @Teorie vSpacing iiieelianisin will now be readily nnderstood upon ret renee to the zioregoing deeoripf n the accompanying' drawing, and it will loe noted 'tliet more or less change may be .made in tlie eomponent parte thereof Withoutdeperting 'from the Spirit oi any invention.
