TYPEWRITER-CARRIAGE RETURN.

Specification of Letters Patent.

Patented Dec. 28, 1920.

Application led November 19, 1919. Serial No. 339,020.

To all whom it may concern:

Be it known that I, LoUIs SCHNEIDER, a citizen of the United States, residing at Clinton, in the county et Henry, State of Missouri, have invented a new and useful Typewriter-Carriage Return; and l do hereby declare the following to be a lull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to typewriter carA riage returns and has for its object to provide means adjacent the typewriter keys and keyboard and mounted in the liront edge of: the frame whereby the carriage may be returned to its initial position by simply sliding a slidable member transversely, thereby obviating the necessity of the operator raising the hand from the keyboard for spacing and shifting the carriage. This is a distinct advantage where the operator uses the touch system as it keeps the hands practically in position over the keys oit the keyboard at all times.

A further object is to provide a carriage return and spacing means comprising a slidable member slidably mounted in the slot in the front of a typewriter frame, said slidable member being spring tensioned and provided with a pulley over which a cord passes. One end of said cord is permanently fixed and the other end leads to and attached to the carriage and its spacing means so that when the slidable member is moved longitudinally the initial pull on the cord will cause a roller spacing operation and a further pull will cause the carriage to be returned to its initial position.

lVith the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth. shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

Figure 1 is a sectional view through a p0rtion of the front frame of a conventional form of typewriter.

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1.

Fig. 3 is a perspective view of the slidable member.

Referring to the drawings, the numeral 1 designates the front extension of a typewriter frarne which extension extends around the key board of the machine. The :front rail 2 is provided with a longitudinally disposed elongated slot 3, in which slot a slidable member 4 is slidably mounted. Member 4 on its upper and lower edges is provided with longitudinal grooves 5 which engage the inner and outer walls of the front bar 2 and form means, whereby the member 4 will be prevented from becoming displaced. Slidable member 4 is provided with inwardly extending horizontally disposed spaced ears 6 between which ears a pulley 74 is rotatably mounted on a pin 8. Extending around the pulley 7 is a carriage operating cord 9, the end 10 of said cord extending through a longitudinally disposed aperture 11 in the slidable carriage shifting member 4 and having its end secured as at 12 in the left hand side of the elongated slot 3, thereby forming a stationary securing point Yfor the ends 10 of the cord 9. The portion 13 of the cord 9 passes over a pulley 14, thence over pulleys located in any suitable manner on the machine and has its end secured to the line space lever 'of the machlne.

It is obvious that this securing means will have to be varied considerably according to the type of carriage and its shifting means. However, it is understood that the portion 13 of the cord 9 may be led to the spacing and shifting mechanism of the carriage according to the type of carriage and that any amount of leads may be used in reaching said spacing and shifting mechanism of the carriage. Secured to the slidable member 4 as at 15 is a coil spring 16, the other end of said spring being secured as at 17 to the frame 1. It will be seen that as the carriage during a writing operation'feeds t0- ward the left that a pull will be imparted to the portion 13 of the cord 9 in the direction of the arrow a which will stretch the coiled spring 16, the function of said coiled spring being to maintain the cord taut during a shifting operation or during a writing operation. During the writing operation when it is desired to space the roller and shift the carriage back to its initial position to the right, the finger of the operator is placed in engagement with the finger engaging member 18 of the slide 4. Then the slide 4 is moved in the direction of the arrow i sli/le 'will Cruise the r which will cause a pnll'o loe impziriel `'the portion 18 oli' lie oord Y' posees over the pulley 'Y and lim ehored is at l2.
