TYPEWRITING' MACHINE.

Application filed February 25, 1928, Serial No. 257,070, and in Germany August -25, 1927.

Improvement in typewriting machines.

My invention relates to typewriters and more particularly to that class of typewritcrs by means of which shorthand or stem)- graphic script may be written.

One object of my invention is toprovide a typewriter in which the keys may be arranged in the customary manner so that everybody accustomed to the standard arrangemcnt of the keyboard may easily learn the use of my improved shorthand type writer.

Another object of my invention consists in the provision of a typewriter by means of which. shorthand script as well as scrlpt in ordinary letters may be typed, as desired.

From another aspect an object of my n 1 vention is a typewriter for stenographic script in which the distance between the typed lines must not by necessity exceed the distance which is ordinarily in use in typewriting script in ordinarily long hand letters.

My inve'ntion, satisfies an urgent demand for a typcwriting'machine by means of which a speed intyping may be attained which is far superior to the speed of ordinary typewriting and equals at least that of stenographing by hand. The typewritten shorthand script looks very similar to the handwritten script and may easily be read by everybody familiar with the particular system used. fore, does away with the inconveniences and disadvantages caused by the well known fact that ordinarily hand written stenographic script can be read and transformed into long hand script only by the same person who took the dictation in shorthand.

By means of my invention it is possible, therefore, to have a letter written in shorthand by one person and transformed into ordinary typewritten script by another person.

My invention particularly contemplates the use of a system of stenography in which a consonant, either a single or a composite consonant, and the vowel associated therewith are represented by a single simple shorthand sign, and in which for representing different syllables comprising the same consonant associated with different vowels, signs are used which are partly alike, signifying the associated vowel by certain char- The invention, there-.

acteristics in their configuration and not, as

in other stenographic systems, by their position in relation to the line.

I prefer the use of such shorthand system to the. use of the mentioned other systems in which the same sign is employed for representing a consonant associated with ditl'erent vowels and is difi'ercntly positioned in relation to the line to express various vowels, bccause a change in the position of the sign in the accompanying drawings as embodied in a typewriter such as shown and described in the German Patent No. 211,568.

Fig. 1 is an elevation, Figs. 2 to 4 are sections along the respective section lines indicated in Fig. 1, Fig. 5 shows an example of the types, Fig. 6 a detail on a small scale.

10 indicates the customary paper carrier or paper cylinder which is journaled in the bearings 11 forming part of a frame consisting of two lateral posts 12 connected with,- each other by an integral palte 13 The posts 12 are shiftably mounted in guideways 13 which are attached to a frame 14. The frame 14 is movable or transportable in axial direction with respect to the cylinder l0 and is acted upon by a. mechanism which moves it. step by step to the left when the keys of the typewriter are successively pressed down. As such mechanisms are well known in the art and do not form part of the present invention, a description and illustration thereof is deemed dispensable herewith. The opposed faces of the posts 12 are provided with grooves for slidably accommodating a frame 15 which may be adjusted in various definite positions relative to the posts 12.

For this purpose, brackets 16 are attached to the-plate 13 and a shaft 17 is journaled therein carrying at its ends levers 18 provided with hooks 19. The frame 15 is formed'at either side with a coveixplate 20 provided with two holes 21 and 22 registering with the respective book 19. The shaft 17 is provided with a handle 23 and a spring 24 is inserted between the same and the post shaft 17 is turned thereby disengaging the hooks 19 from the holes. The posts 12 may then be lowered by hand until the holes 22 are in registry with the hooks 19. Upon releasing the handle 23 the hooks, owing to the action of the spring 24, will slip into the holes 22 and will hold the posts 12 and the frame 15 in their new relative position.

' In order to facilitate the manual adjustment of the posts 12' relative to the frame 15 and to avoid a ammingofthese parts, special provisions are made to prevent an angular displacement of the posts 12.- These provisions comprise a shaft 25 journaled in the brackets 16 and having a pinion 26 fixedly attached to each end. The pinions 26 are meshing with teeth 27 cut into the opposed edges of the cover plates 20. A displacement of the one post 12 relative to the frame 15 causes a rotation of the co-ordinated pinion 26 and thereby a corresponding displacement of the other post 12, whereby the posts 12 are prevented from jamming.

The frame 15 forms two horizontal flanges 28, 29 forming a guideway for a roll 30 carried by lever 31 which is keyed-to a shaft 32. The shaft 32 is supported in stationary bearings attached to the frame of the typewriting machine and is provided with a mechanism not shown, for adjusting the shaft 32 and its lever 31 in one of three angular positions indicated in dotted lines. As such mechanism are well known in the art it will not be described in detail. By this adjustment of the shaft 32 the roll 30 maybe lowered into the positions 30 or 30.

The frame 15 and the posts 12 connected with the roll are correspondingly shifted in the guideways 13. I

The paper cylinder 10 co-operates with a type carrier carrying two groups of types. The one group comprising the types 34, 35 and 36 is intended for use in writing shorthand script of some graphic system as distinguished from geometrical systems. The distance of these types equals the amount by which the frame 15 may be raised or lowered byaction of the afore-mentioned angular adjustment of the shaft 32. The types 37, 38, 39 which serve for writing ordinary script are arranged at the same distance from each other. In the position shown in the drawings the frame 15 occupies its uppermost position. In this position the type 341 is co-operatively correlated to the paper cylinder 10 and may be brought into printing position by striking the key 40 as will be easily understood from Fig. 5 which is self explaining, and does not need a description as the details shown therein are simple and well known in the art. By

changing the angular position of the lever 31 which ordinarily is effected by pressing upon special keys, one key being provided for the uppermost position and another key for the lowermost position of the lever 31, the frame 15 is lowered by one or two steps and either the type 34 or the type 36, as desired, is brought into operative position.

As the distance between corresponding types of both groups, such as the distance between the types 35 and 38, corresponds with the distance between the holes 21 and 22, the paper carrier occupies the same position relatively to the'respective opposed group of types on the type carrier regardless of whether the hooks 19 are engaging the holes 21 as shown or the holes 22.

As the three types 34, 35 and 36, being carried by a common type carrier, are coordinated to the same key they serve for printing shorthand signs which represent the particular consonant with which said key is marked and various vowels coordinated with said consonant. 'Ihe-configuration of three types, therefore, is preferably such that a certain part thereof is equal in all three types. This part is characteristic of the particular consonant, the remainder of the three configurations, however, is differentiated in shape to express various vowels which may be associated with said consonant to form a syllable. The term consonant as used herein and in the claims is intended to cover also composite consonants like st or ch etc. If three shorthand types are coordinated to the key marked with a consonant, as in the example described, only three different signs are available for distinguishing the various vowels but my experience has shown me that three signs are perfectly suflicient for practical purposes. In this case, each sign, designates a vowel of a vowel group and the reader of the script must guess from the sense thereof which particular vowel of that group is the one which ismeant by the .sign. In the German language the three groups comprise e, ei, i and on, or a, an, a and an, or o, as, u, and ii respectively. I

In Fig. 6 I have illustrated by way of example the configuration of the types 34, 35 and 36 on an enlarged scale. All three types are coordinated to a key marked with the consonant D. That part of each type situated above the dotted line is equal to the corresponding part of the other two types. The term equal applied to these parts does not only indicate the identity in shape but it characterizes also the identic position which these parts assume in printing positionin relation to the line. Those parts of the configurations which are situated below the dotted lines differ from each other and indicate the vowel associated with d. The type 35 may, therefore, designate in the Ill) German language, for instance, de, dei, di, or deu, the type da, dau, da or den, and the type 36 do, do, du or dii;

The lower group'comprising the types. 37

38and 39 corresponds with the conventional .means, such as the adjustable shaft 32 with its associated parts and the adjustable posts 12, must be provided by means of which anyone of the shorthand types may be selected for typing, similar to the optional selection in ordinary typewriters between small letter types and capital letter types which are also coordinated to the same key and may be selected by special keys.

The fact that a given consonant is always written by means of the same key no matter with what "vowel it is associated, affords the valuable advantage that a key board may be used which substantially corresponds with the standard arrangement. This renders it possible to provide ,ordinary types in coordination with the stenographic types so that both kinds of script may be written on the same machine without requiring special study and exercise, or any other adjustment than the simple shifting of the posts 12 from their one position into their other position.

WhatI claim is 1. In a typewriting machine, the combination comprising a key provided with a mark representing a consonant, a type representing said consonant in an ordinary smallletter, .a type rep'resentmg sa1d consonant 1n a capital letter, three shorthand letter types of configurations having an equal part to represent said consonant and a diflferent part to represent a vowel group associated with said consonant, a mechanism operatively connecting said key with said types to cause upon the pressing of the key the movement of one of the types into printing position and'selecting-means for selecting any one of said three types for the movement into said position.

2. In a typewriting machine the combinetion comprismg a key provided with a mark representinga consonant, three shorthand .letter types. of configurations having an equal part to represent said consonant and I a different part to represent a vowel group associated with said consonant, a mechanism operatively connecting said key with said types to cause upon the'pressing. of the key the movement of one of the types into printing position and'selecting means for selecting any one of said three types for the movement into said position.

3. In a typewriting machine, the combination comprising-a key provided with a mark representing a consonant, a type carrier having two groups of types one group including an ordinary capital letter type and an ordinary small letter type of said consonant, the other group including three shorthand letter types of configurations having an e ual part to represent said consonantand a di erent part to represent a vowel group associated with said consonant, a paper carrier,

an operative connection between said 'key and said type carrier to movethe latter towards said paper carrier and a selecting mechanism for bringing said paper carrier and any desired type of said type carrier into printingl position to each other thereby permitting t e samekey to be used for typewriting a shorthand sign as well as an ordinary letter.

In testimony wh'ereof I aflixed my signature.
