Application filed June 2, 1924. Serial no. 717,209.

My invention relates to typewriting ma chines, and has for its object to provide a code system which is particularly adapted for use in connection with such machines.

prise lower case f, p,.v, in one group; 0, g, j, k, q, s, X and z-in a'second group; d and t in a third group; 1. by itself; m andn in a fifth group ;.'and r by itself. These dif- 5 More specificallymy invention relates to the "ferent groups are separately distinguished code system sometimes referred to as the Russell index. This systememploys six basic consonants b, c, d, l, m and r some of which have a plurality of phonetic equivalents. Thus Z) stands not only for b but also represents or stands for f, p and v; 0 stands for c, g, j, k, s, x and z; 0? stands for d and t, Z stands for itself alone; 112. stands for m and n; and 7- stands for itself alone. For this system the vowels are disregarded as well as the consonants y, w and h. These key consonants may be grouped in desired. combinations, thus :greatly simplifying index systems based primarily on the usual alphabetical principle; In the present system heretofore it has been the custom to memorize the key letters .and their equivalents. My improvements consist in distinguishing all of the key letters or characters of thecode system by the same mark or characteristic, such as a star, a period or the like, thus providing an automatic checking or designating of such code letters or characters as they are written, and 0b viating the necessity of the operator memorizing the key letters or checking them by hand at a separate operation,- as has heretofore been the practice. r I

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

One form'of my invention is illustrated in the accompanying drawings wherein,

Figure l is a fragmentary plan view of a set or series of type bars embodying my invention, the type blocks on the ends of the type bars being shown as they lie in, the basket.

Figure 2 is a standard Remington keyboard as modified for use with my invention. Figure 3 illustrates various spellings of a name with code letters indicated.

Figure 4 is a fragmentary view of several type bars and their type blocks drawn to an enlarged scale. p In the index system to which I have adapted my invention, the key letters comaccording to the code system aforesaid,but P for the purposes of my invention-I designate all of the characters of all of the groups by the same mark or indicating sign, preferably, as shown herein, a star or asterisk. Referrlng to Figures 1 and 4 of the drawin each type bar 1 carries a type block 2 whic is provided with an upper case character 3. an

a lower case character 4. I havenot shown in Figure 1 all of the characters on the type blocks. but have only shown the code characters, alL-of the code characters being lower case letters and arranged at the rear end'portions 'of the type blocks. As-' sociated with each of these code letters is a star designated as 5, the star being the preferred device for distinguishing or designating the code characters. These stars 5 are so related to their associate letters that they will print, simultaneously therewith and slightly above and at the right-hand side of their letters, resulting in a line of stars distinct from the line of letters. Referring to Figure 2, wherein the key caps or buttons of the standard keyboard are designated as 6, it will be observed that I have provided the keys of all of the code letters with the distinguishing mark or star.. This gives visual indication of thefull acter keys. a 1 'In Figure 3, I have illustrated the variants am at of a single name as follows: Farnam,

- *i. 1* -x-* Farnum and Farnham, as they appear; hine emwhen printed byja typewriting mac bodyingmy invention. It will be observed that the keyor code letters are the same in each instance, namely r, m and n, and

that these ke letters are visually indicated or distinguis ed by stars, the stars appear.-

' letters and so I I mg in a line above the ke that these letters may r'ea y be noted at a glance. .Thishelps to bring out certain of the advantages of my invention, namely, the

operator is not put to any mental effort to remember the key characters, the, liability of error is done away with, and-the key characters are automatically checked by a uniform mark, thus sathe operator from doing this with a pencil or otherwise.

set of code-char- I 11. A device of the character described, including a tubular driving stem having an internal annular shoulder forming a seat, near its lower end, a blade carrier movable through said stem, and having an external annular shoulder adapted to rest on said seat to support said carrier, expansible blades carried by said carrier,-and means for expanding said blades beyond,. and withdrawin them within said carrier, said J1 means including a wedge like web which works between said blades.

In testimony whereof I have signed my name to this specification.
