Specification of Letters Patent.

Patented Mar. 28, 19131..

To all whom it may concern:

Be it known that I, CHARLnsP; MosHER, citizen of the United States, and resident of: the borough of Brooklyn, city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Type-lVriting Machines, of which the following is a specification.

My invention relates to typewriting machines and more particularly to means for supporting and guiding the carriage and for maintaining the bearing rollers therefor properly spaced with reference to one laanother and to the tracks on which they ear.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices to be hereinafter described and particularly pointed out in the appended claims.

In the'accompanaying drawings wherein like reference characters indicate; corresponding parts in the various views,Figure 1 is arear elevation showing the upper part of the typewriting machine embodying my invention. Fig. 2 is a transverse sectional View of the same. Fig. 3 is a fragmentary transverse sectional view, the section corresponding to Fig. 2, but showing the parts on a larger scale and with some of the parts represented in Fig. 2 omitted. Fig. 4 is a detail ,perspective view. of one of the separators. I

'I have shown my invention embodied in the present instance in a front-strike typewriting machine in which the carriage 1s 'fixed against swlnging movement and is wholly supported in the rear of the plat-en, and in which there is no obstruction to the usual upwardly swinging type bars striking the front face of the platen and an unobstructed view of the printing line is atforded. Itshould be understood, however, that my invention may be embodied in other styles of typewriting machine's.

The top plate 1 of the machine has brackets 2 fixed thereto by screws 3. An upper fixed guide rail 4 is secured by screws 5 to the brackets 2. A corresponding lower fixed guide rail 6 is secured to lugs 7 on the brackets 2; screws 8 being employed to secure the rail 6 in place. These fixed guide rails are alike so that a description of one applies to the other. The guide rail 4 has inclined tracks 9 formed thereon throughout its entire length for cooperation with cylindrical anti-friction bearing rollers 10. The tracks 9 are inclined in opposite directions and the cylindrical bearing rollers have their axes arranged at corresponding inclinations. The upper tracks 9 are inclined downwardly and outwardly from each other, whereas the lower tracks 9 are inclined upwardly and outwardly away from each other. The tracks 9 and 9 are formed as flat.- bottomed grooves extending throughout the length of" the fixed rails it and 6 respectively. There are preferably four bearing rollers 10 for the uppertracks 9 and four bearing rollers 10 for the lower tracks 9 as will be seen by an inspection of Figs. 1 and 2.

The carriage comprises a rear guide bar 11 which constitutes the sole support for the carriage through the cooperation of said bar with the

bearing rollers

10 and 10 Forwardly extending end bars 12 project from the rear guide bar 11 and have hearings in which a platen shaft 13 is received, said platen supporting the usual cylindrical platen 14. The guide bar 11 has oppositely inclined tracks 15 formed at the top thereof, said tracks being inclined and arranged parallel with the tracks 9 on the fixed guide rail 4. The bottom of the bar 11 has tracks 16 formed thereon which correspond to and are parallel with'the inclined tracks 9 on the fixed rail 6. The carriage is thus mounted for movement on the

bearing rollers

10 and 10 to travel from side to side of the machine over the top plate and is fixed against swinging movement and .guided firmly by the bearing rollers and the cooperating tracks. The axes of the various bearing rollers are preferably arranged at an angle of about 45.

and the tracks '15. This separator ex 'pends longitudinally of the-carriage and is pro The tracks at the upper and lower sides of the carriage bar 11 vided intermediate the roller receiving openings 17 and intermediate the oppositely inclined rollers with a longitudinally extending portion which is termed. with a rack 19. The rack is produced by punching out portions of the metal to form a series 01 interdental openings in the separator, which latter is preferahl; formed of sheet metal. It will he observed that the portions or cars '20 of the separator, in which the roller receiving openings 17 are formed,

are inclined to correspond with the inclination of the faces of the tracks 9 and 15.

lihen the separatm' is in place the raclr 19 is its travel from side to side of the machine,

as will hereinafter more clearly appear. The gal! 21 is fixed. upon a shaft mounted to turn in a hearing in the bar 11. The rear end of this shaft has a gear 91'- fixed thereto which last mentioned gear is twice the diameter of the pinion or gear 21. The gear 2 1 meshes with a rack 25, fixed to the upper guide rail l by screws 26. The rack there tore is connected to the frame of the machine and remains lived and it extends substantially througlnimt the length of the fixed guide rail -jland throughout the lei'iglh oi" the travel of the carriage. it will he understood that the travel of the carriage carries the gears 21 and El with it and the engagement of the gear 24: with the fixed rack 25 will produce a rotative movement ol? this gear which is transnntted to the pinion 21,

and this motion in turn is tranf-iinittml to I the roller separator tlmmgh the engagena'nt of the pinion with the rack 1f). The client of the movement thus lranrjnnittial to the roller separator l8 to cause said separator and the hearing rollers 10 controlled -lhere by to move a distanre eorrespomling to onw half the travel of the carriage in the movement oi. the latter 'l'rom side to side ol' the machine which also corrrsponds lo the nut-- nral rolling action of the rollers on their tracks. in this manner the l'UllQl'w' l() are at all times properly positioned with reference one to another with retina-nee to the earriage, and with rcteremxe to the frame of the machine. The rollers '10" are likewise n'ovided. with a separator and with m ans similar to those described above for controlling the position of the separator.

i l l l These parts are substantial duplicates of those jireviously described and the same refas the upper separator, as indicated in Fig.

1, both separator-s will he moved a corrcspomling distance during the travel of the ca rri a ge.

From the foregoing description it will he seen that l have provided simple and el'li cit-n; means for mounting the c: riago and for controlling the positions of the bearing rollers therefor at every point in the travel of the carriage.
