Patented Aug. 25, 1914.

No. 447,749. Divided and this application filed October 53, 1912. Serial No. 727,459.

To all whom it may concern! Be it known that I, Gnonon Kenn ANDER- SON, a citizen of the United States, residing in the city and county Q If Philadelphia, in the Commonwealth of Pennsylvania, have invented certain new and useful Improvements in Shorthand Type-Writing Machines, of which the following is a specification.

The object of this invention is to eiiect certain improvements in the construction and operation of shorthand typewriting machines, hereafter usually spoken of as shorthand typewriters, especially the method of supporting the key-bars and the arrange ment of the key-boards, and the invention resides in the novel features of construction and operation set forth in the following specification and claims and illustrated in the annexed drawings, in which- Figure 1 is a plan view of the machine, showlng the arrangement of the keys and key-buttons, the separate mounting of the printing keys and shift keys, the typeframes and part of the feed mechanism and rear portion of the machine. Fig. 2 is a sectional view of the printing keys and shift machine and means for supporting same, on the line A A of Fig. 1. Fig. 3 is a side view and Fig.4 a plan view of section of shift key bar, showing tubular bearing and method of attaching same to the key-bar. Fig. 5 is a plan view of the keyboard of my machine where code mark keys are substituted for shift keys, and Figs. 6,

- 7 and 8 are detail views showing method of supplorting the key-bars.

T is application is, in part, a division of my pending application 447,749, filed August 10, 1908, to which reference is made for a fuller description of the workings of the machine as a whole.

On each side of the base of the machine are the upright side plates 1, l, in which are revolubly mounted the type-frames, 14, on the journal rod, 13, and in which is also mounted the feed frame, 16, on the pivot rod, 15. The three type-frames are provided on the lower side with rows of type as explained in my Patent 581,570, and in my pending application 447,749, and beneath these type-frames are located, side by side,

the printing keys, 5, in positions correspond-' ing to the rows of type on the type frames above them, all of which is fully explained -in the patent and application for patent just referred to. This explanation is not repeated here because the advantages of arranging the key board of a shorthand machine are not confined to machines where the method of supporting the key-bars or the method of printing would correspond to those described in this application, but would extend and apply to any writing maching wherein a number of keys could be struck simultaneously and the key board of which was adapted to a substantially similar arrangement. I

Fig. 1 shows a portion, 17, of the'feedframe, 16, resting on the ends of the printing keybars, 5. The printing key-bar's may, so far as the arrangement of the key-board is concerned, bemounted in a guide block as described in my precedingpatents, or in any other suitable way, but 1n. the present instance they are provided with long, tubular hearings or hubs, 3, as shown in Fig. 5, and as also shown in Figs. 6, 7 and 8, fastened to the key-bar by a thin strip of metal, 18, which fits close to the key-bar on both sides and is soldered, riveted or otherwise secured thereto, and through which, beneath the key-bar, a piece of tubin r passes and is soldered or otherwise fasteneii, and through this tube the pivot rod 9, passes as shown in Figs. 1, 5 7 and 8. The advantage of this arrangement is that the key-bar itself is not weakened by the pivot rod going directly through it, as heretofore, and the size of the pivot rod maybe greatly increased, while the bearing secured is very much longer than the thickness of the bar, and especially is this the case when, as shown in Figs. 1 and5, the key-bars are mounted in more than onerow, The pivot rods, 9, are sup ported by the frame. 8. which is secured to the base of the machine and the endsof which are bent up as shown in Fig. and these pivot rods are held in position laterally by the clamps, 10, at each end of the supporting frame, 8. The type frames are moved to bring thecharacters in the vari ous rows'of type immediately above and opposite the printing keys, by the shift keys, 6, as already described in my pending application 447 ,749, and in order to shorten the stroke of the shift keys, they are mounted closer totlfie" operator and farther from'i the type 5 frames than the printing keys, as I shown inFig; 1, on;--a, pivot rod which sup ports all of them and is secured in the lugs 2, 2, at each side of the machine. These shift keys are provided with long, tubular bearings beneath them, as shown in Figs; 1, 2, 3

and 4, and similar in construction to the bearings of the printing keys, which have already been explained. In order to' allow the free movement of the shift keys without 7 interfering with the printing keys, they are mounted beneath the'latter', that is on a lower plane; 1 an "arrangement which, as

shown in Fig. l,'perinits 'one seriesof keys to, freely cross ano'ther'series-a very important advantage Where space is so limited as'in a machine of thislcharacterl' Only two of the shift keys require springs, and these; are provided withv spiral springs, 11, as shown in Fig. 1. The figure shift, 7,'is so fully described in application 447 ,749, that only its location will be indicated here, as has been done in Fig. 1. The shift keys are bent as shown in Figs. 2 and 3, to make them high enough toipass over the feed frame, 16., and low enough to be out of the way of the printing keys. The threetype frames, 14, are revolubly mounted on the pivot rod, 13,

which is secured in the upright side plates,

l, 1, of the machine. These type frames are provided with type as follows:

" Left hand type frame-consonants:

which, referring to the'key board, Fig. 1,

are the bottomletter on each key button. If

the first seven'printing keys are struck simultaneously with the left hand shift key, th

following letters will. be printed:

' S' P BF G L R which appear on the key board as the second letters from the bottom of the respective keys. If the same printing keys and the next 1 shift key are struck simultaneously, I

they "will pr-int, the following:

' s'M'NvKLY which appear on the key board as the'third letters from thebotto-m--. of. the respective I keys. If the same keys are struck simultaneously with both the left hand shift keys,-

the following characters, will be printed:

sozxr,

which appear on the key board as the top letters on their respective keys. "If the three vowel keys are struck simultaneously with theshift key marked vowels, on Fig. '13,"-the following letters will be printed:

O U I i I If the six remaining printing'keys' are struck simultaneously with the right hand consonant shift, they will print ,LKMrrs The shift key for figures operates as ex plained in my pending application 447,749, and is located between the printing keys and the type frames, to be out of the way of all the keys that are used in spelling-word's,

The central type frame, carrying the vowels, is provided with a long. arm,-'20, as shown in Fig. 1, the purpose of which is fully explained in mypending application 447,749,

and in order to permit the vowel shift-key to operate this iframe' and at the same time have its key-button located next to 'the ke y buttons of the vowel keys, the end of this" shift keyis bent so as to come around the end' of the adjoining shift key, .6, as" shown in Fig. 1.

While the letters and characters here shown are the ones recommended, other let ters and characters might be used without departin from the spirit of this invention. So also tie type might be on complete type wheels similar to those'used in other writing machines, instead of on type segments or,

as they have been termed, typev frames, as here illustrated, or other meanswell known in the typewriting art or means not'yet' devised might be used for printing letters without departing from the spiritof this invention, which relates mainly to the ar rangement of the keys themselves and to the method of supporting the key-bars when keybars of the kind herein described are used in connection with the key board here' shown; a

1 In a machine of this character," where mind and hand must act in unisonseveral times each second, the arrangement'of the key board, the'arrangement of the key buttons onthe key board, is of the greatest importance, a'ndthe arrangement shown in this application is the result of a great deal of study and many. practical experiments.

The purpose of thisarrangementfis (1) to arising from uncertainty as to whether he is striking a shift key or a printing key-g- (3) to further assist the mind of the operator by locating this special group of shi t keys entirely apart from the printing keys and where they can be operated by distinctly different members of the hand-the thumbs, leaving all the fingers to operate all the printing keys (4) to assist the hand of the operator by locating the shift keys, which are so frequently used,'near the center it,

of the key board, where they, can be oper ated by the most active members of the hand; and (5) toflaassist the mind of the operator byjlocating each shift-key as close as practicable to the group of printing keys, in connection with which it is used.- While printing keys each operating in connection with a plurality of printing characters com-- the idea] arrangement of a keyboard is one "embodying all these features, as illustrated In board might be arranged embodying only some of them and securing apart of the-ad-j vantages herein set forth, without departing from the spirit -of thisinvention; and" it is also obvious that the method of supporting the key-bars herein described might be irsod with an entirely difierent key board'- or that this key board might be used with key-bars and printingarrangements of an entirely difi'erent character from those herein do"- scrib'ed, without departing from the spirit I of this invention.
