Specification of Letters Patent.

Application tiled October 17, 1908. Serial No. 339,938.

To all whom may concern: I l

Be it known that l, JUAN B. VIDAL, a citizen of the I Republic 0i Cuba, and a resident of Habana, Cuba, have invented a new and Improved Carriage-Actuating Mechanism for Type-Writers, oi which the following is a l'ull, clear, and exactl description.

This invention relates to certain improvements in typewriters and more particularly to the means em-- ploycd for returning the carriage to its original position at the right-hand side of the machine after each line is written, and for rotating the roller to bring a fresh portion of the paper into operative engagement with the type. i

lhe object of the invention is to vprovide means Whereby'the carriage may be moved longitudinally and the roller simultaneouslyrotated Without removing either hand from the key-board.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters or' reference indicate corresponding parts in all thev figures, in which l Figure l is an end elevation of a portion of a typewriting machine provided with my improved attachment; Fig. 2 is a front elevation oi a portionthercof; and Fig. 3 is an end elevation oi a slightly modified form of con- The -frame l of the machine may be of any suitable form commonly employed, and the carriage 2 is provided with anti-friction rollers 3 and a large roller 4 for receiving the paper. The carriage is free to move longitudinally oi the machine and is drawn toward the left-hand. by means of any suitable tension mechanism and escapement operated by the type keys but not ment toward the lel'tliand end of the machine, itis custernary to remove one hand from the keyooard and improved construction the lever 5 is pivoted by a pin 6 to the iront portion of the carriage and a pawl 7 is carried by one end oi this lever, the pawl being heldby a spring 8 in. operative engagement with a ratchet Wheel 9 carried by the roller 4, By depressing the outer end of the lever 5, the pawl engages with the ratchetto rotate the roller the desired amount.

ln order to return the carriage and simultaneously rotate the roller, I provide a bracket l0 secured to the frame of the machine and carrying a small pulley'll, While a second bracket carries a roller l2. Passing over these two rollers and through an opening in a lug 13 on the lever 5, is a cord or Wire i4 of any suitable material, and having one ond lthereof attached to the carriage at a point 15 and the other end attached to Wire and operating the carriage. .as the lower end of the `cord is pulled down, ard the carriage is moied toward the roller l1, and, at the time that it reaches the limit of its movement, the lever 5 is directly above the roller ll and further pulling on the end of the cord. 1li serves to depress the lever and rotate the roller. Any suitable means may be employed for pulling downward on the cord 14, and thismeans may be operated by the hand or the foot of the operator. v

In my preferred construction, namely, that illustinted in Figs. l and 2, I employ a lever l5 having one end pivoted to the frame of the machine adjacent the rear portion thereof-by means ot' a pivot'pin l?, and. having the free end oi the lever secured to the loner-` end of the cord 14. A second lever 18 *connected to the lever 16 adjacent the pivot pin l?, anda slot 19 is provided in one of these levers at the point ol-con" nection, whereby certain Afreedom of motion is per`- mitted. -A third lever 2l) lis pivoted at the ont portion of the machine and its inner end is connected to the lever 18 by a pin 2l.` A slot is provided in vone of these levers to permitl the longitudinal movement of the pivot pin carried by the' other lever. The enter end of the lever 2O extends to a point outside of the traine of the machine, and preferably terminates at a distance somewhat in iront of the key-board 'and at a slightly higher level. A plate 22 is carried by the outer end ol the lever and located in a position adjacent the ball or palm of the hand of the operator. Upon depressing' theplate 22, the inner end oi the lever 2O is raised and the rear end .of the lever i8 is,VV

depressed to depress the lever l and draw down?" Ward the end of the cord 14.

By the use or the improved construction above de` scribed, it is entirely unnecessary for the operator after having written a complete line, to withdraw his hand from the key-board and more the carriage baci: to its original position and rotate the roller. All that is necessary is to depress the pla'te or keyf normally located adjacent the hand of the operator, andthe carriageis not only returned toits original position," but the roller is simultaneously rotated. A great deaf.

of time is thus saved and no unnecessary movements vso of any kind are required,the desired object being acl complished by a simple depression of the Wrist, rather than a movement. of the entire handto a separate por-` tire width of the machine. v

lf desired, instead of the lever construction above described, the cord la may be extended;- downward o.

to a position adjacent the floor and connected, to a treadle 23, adapted to he depressed by the foot of the "19d tion oi the machine and then moving it across the en-4 operator. v In this form the operator need not remove means for drawing downward on the end of Lhecord or" ,I the lingers from the key-board, but whena'line is complated all that is necessary is to press down ch tine l treu-'lle 23 and the carriage will be returned to its original position und ille roller rotated the desired amount.

Various changes may bc iliade in the construction y bc dssigued lor accomplishing the objects above set forth and Without departing from the spirit of my inventon. l

Having thus described my invention, l claim as new and dcsirc to secure by Letters Piment:
