Application 'filed Marcil 15, w24.

This invention has relation to certain new and useiul improvements in a typewriter key board and has for its primary object the provision ot an auxiliary key board which may be readily incorporated in a standard typewriter when building the same or adced thereto after completion of the regular or standard typewriter, with the keys ot the auxiliary key board substantially corresponding to the keys ot a piano, so that anyone used to playing the piano may readily attain speed and accuracy in operating the typewriter.

The invention has for another object the provision of a key board tor ay typewriter with the keys arranged similar to a section et the piano key board, thereby placing all of the keys in two horizontal planes instead et three or `more horizontal planes or banks, as in the present typewriter| key boards.

rlhe invention has for another object the provision of a typewriter key board oit' the character stated in which the keys ot the new key board structure will be arranged in a simple and compact manner, so that all of the lingers may be employed in a natural manner, without the necessity of raising and lowering the entire hand to reach upper banks et keys, thereby giving' an eas, `free rapid and accurate use et the fingers with a uniform pressure on all ot the keys while typing. the keys which are required tor more frequent use being' arranged in the centre et the new key board, where they are always directly beneath the first and second iinn'ers and the thumbs.

rlie invention has tor a turther object he provision of a typewriter having; a key board o the character stated a a line spacing; and carriage retoruling;Y bar extending; across the iront oli the keys and operable by the thumbs witaout the necessity ot raising; the hands from the key board.

it.. still further object et the invention vesid s in the provision ol typewriter hav- ...fr a tlat keyboard with the keys ont olonated term and similar to the keys of a Diano boarl. and connected with the .espec-tive type bar operatingv levers carry- 'g ular the usual 'form ot keys on the reg) or ordinary key board, tion ai i o tion oit the the accoinpanyire Serial No. 699,530;

tered, with the exception that the former shift keys are replaced by a shifting` mechanism controlled by the ieet or knees of the operator. y

A sti-ll further object ot the invention resides in the provision of a typewriter of the character stated in which the keys of the new key board are all parallel and separated about the same distance apart as the piano key board and all of the parts of simple construction and compact arrangement, so as to assure the highest efficiency and speed et operation, without requiring prolonged training,Y and practice oi the operator.

Nith the foregoing and other objects in view, as will appeal' as the description proceec s, the invention consists in the novel construction, combination and arrangement ot cri-operating elements as lun'einatter more specifically set forth, claimed and shown in im drawings, forming; apart ot the present application, and in which- Fig. l is a plan et the improved typevwriter with the new key board incorporated therein.

Fig. 8 is an enlarged detail perspective et one et the keys of the new key board to disclose clearly the construction thereof.

Fig. 9 is a fragmentary detail elevation et part et the improved carriage shift mechanism to be co r trolled by the toot e knee ot. the operators Referring more in detail to the drawings in which similar reference characters designate corresponding parts throughout the several views, it will be noted that the key board frame 10 is provided beneath the main frame 11 of the typewriter and has its reduced lower portion extended forwardly past the lower reduced forward portion 11a of the main frame 11 and which reduced forward portion 11a serves as the frame for the usual or ordinary key board 12 as shown clearly in Figs. 1, 2 and 4. The extended reduced lower portion 1()a of the frame 10 forms side members for protecting the elongated flat keys 18 and 14 of the improved flat key board. The keys 13V are similar to the white keys of the piano key board, while the keys 14 correspond substantially to the black keys of the piano key board. The keys 13 and 14 areconnected respectively by the separate connecting members 15,Y to the type bar operating. levers 16 of the corresponding keys 17 of the key board 12. This may be readily understood by referring to Figs. 4 and 5. Each of the keys 13 and 14 of theimproved key board includes a shank 18 with a bifurcatedr rear end 19 having transverse concave recesses or pockets 2O in the inner face, so that the shank 18 -may be readily mounted on a supporting rod 2l extended transversely in the lower rear portion of the frame 10. It will be noted by referring to Fig. 4, that two rods 21 are employed and the shanks 18 of most of the white or lower keys 13 are mounted on the lower rod 21 and the Shanks 18 of the upper or black keys 14 are mounted on the upper rod 21. It will also lbe seenfrom Figs. 2, k4 and 8 that each key shank 18 has a binding screw 22 secured therein for drawing together the bifurcated or separated portions of the rear end thereof and holding the shank 18 in proper position on the rod 21 on which it is mounted for operation. It will, therefore, be seen that when a key 13 or 14 is depressed, the proper type bar operating lever 16 will be operated, the same as -if the key 17, mounted thereon, had been depressed in the usual manner. The connecting members 15 are preferably flexible, as indicated in the drawings, so that if the operator desires to use the ordinary or upper board 12, the operation of the keys 17 thereof will not affect the keys of the improved Vor'latlower key board. This may be readily apparent by referring to Figs. 4 and 5.

Extended transversely through the frame 1.0 are a pair of spaced horizontal transverse rods 23, which are arranged above one another and across the shanks 18 of the lower and upper keys for the improved flat key board, as shown clearly in Fig. 4. Upstanding spaced plates 24 are carried on the rods 23 which are positioned between the shanks 18 to separate the same and prevent side movement thereof toward one another. The plates 24 are located intermediate the ends of the shanks 18 and mounted, by turned' lower ends 26, on the bottoni plate 27 of the frame 10. This may be seen clearly in Figs..4 and 7. It will be seen that the plates 24 and 25 co-operate to retain the shanks 18 in properly spaced and parallel position throughout their entii'e length. The differentkeys of the improved flat key board are shaped to correspond with the white and black keys of a section ofa piano key board, as will be clearly seen from Figs. 1, 6 and 7 the keys representing about one and one-quarter octaves, as will be readily seen by referring to Fig. 1. The respective keys 13 and 14 of the flat key board are connected with the type bar operating lever 16 of the correspondingkeys 17 of the upper key board 12. board is necessarily of a special shape and, therefore, will'be described in detail, beginning from the left side of the key board. The first key is Hat and corresponds in shape to the key known as C on a piano key board. This key is connected with the type bar operating lever 16, operating the type bar' carrying the two and the The next key is a black key andraised above the white keys, corresponding with the key known as C sharp on the piano key board. This key operates the type bar operating lever 16 controlling the type bar carrying the letters y, Y and the numeral The next key is a white key corresponding with D on the piano key board. This key controls a type bar carrying the letters v, V and The next key is a black key corresponding to D sharp on the piano key board and controlling the type bar carrying The keys thus far described are carried on the upper shanks 18.

The inner section controls n type ber carrying Z, Z and l eind is mounted on one oit the upper shrinks 18.

The nent key, which may be termed the centre key ot' the key board, represents G sharp of the piano key board and is, thereit'ore, a blnck or raised key. This key is known es the spacer, is mounted on an upper shank i8 and operates the spacing mechanism ot the typewriter. This takes the pince of the usuel space ber intended for operation by the thnmb, on the ordinary typewriter.

The keys to the rightof the spacer key correspond to .the keys to the lett thereof, so as to continue the representation et the pieno key bonrd. ln other words, the rst key siter the spacer represents the key of it on the pieno key board and corresponds with the key representing G1, being, cut transversely into three sections as disclosed 'for the key representing G The central section oi" the key representingl A on the pieno key bonrd controls the type ber carrying e, lil end 3 The outer section contro s the type bor carrying t, T enc The inner section controls the type ber carryine` p, P and (l.

The

letters or the third set of characters on the type bars. This should be clearly apparent by referring to the drawings.

Special mechanism is provided for operating the line spacing mechanism and returnine the carriage without the necessity of the operator taking the hands off of the lower flat key board. lhis'mechanisin includes a line spacing bar 34 extending across the front of the frame l0, along the outer ends of the white keys 13 of the lower fiat key board. The bar 34 has its ends mounted on the forwardly projecting ends of the side levers 35, located on the outer sides of the frame l0 and having their bifurcated rear ends 36 pivoted on the supporting'rod 37 which extends transversely through the lower rear corners of frame l0, Above the forward portions of one of the levers 35, is a fixed block 38, to which is pivoted the forward end of the lever 89 by a suitable pivot member 4G. rlhe levers 35 are inclined forwardly, while the lever 39 is inclined rearwardly and connected intermediate its ends with the lever beneath the same, by a link 4l. The levers 35 and 39 are resiliently retained in their normal or uppermost positions by a spring 42 having its lower end pivoted to one of thelevers 39, while the upper end is mounted on the upper arm 43 on this side of the machine. The arms 43 are carried on the ends of a shaft 44 which is rotatable through the upper forward corner of the main part of the frame 10. The arms 43 are directed forwardly and slightly inclined and have pivoted to their outer ends the upper extremities of the connecting rods 45, the lower ends of which are pivoted to the levers 35, preferably forwardly of the links 4l. llpstanding bearings 46 are carried on the rear end of the lever 39 with a pulley 4T mounted therein. Y

The cable 48 extends around the pulley 47 and has one end fixed to the angular' bracket 49 carried on the frame 11, as shown clearly in Fig. 2. The cable 48 extends freely through the upwardly inclined line spacing lever 50, on the carriage 51. A knob 52 is carried on the cable 48 for operating the line spacing lever 50, as will be later clearly understood. The cable 48, after extending across the carriage 5l, passes around a pulley 53 rotatably mounted on a shaft 54 projecting from the upstanding end 55 of the bracket 56, which latter is secured to one end of the typewriter carriage bed frame formed by the upper part of the main frame 11 and extended outwardly from the same. A depending bracket arm 57 is carried by the bracket 56 and a swinging arm 58 is pivoted at its lower end to the lower end of the depending bracket arm 57. l A pulley 59 is rotatably mounted in the upper end of the swinging arm 58 and the cable 48, after extending around the pulley 53,V passes around the pulley 59, as shown clearly in Fig. 3. The cable is then turned back and fastenedby its end to the upstanding arm 55 of the bracket 56, beneath the pulley 53. The swinging arm 58 is resiliently retained in one ofits'extreme positions (leaning toward the typewriter frame l1 and carriage 5l) by means of the spring 60 having one end attached to the swinging arm 58 and its other arm attached tothe typewriter frame l1. In order to yassure proper operation and guiding of the cable 48, a guide pulley 6l ismounted in an upstanding bracket 62 on the end of the typewriter frame ll on which the lever 39 is positioned, the cable 48 passing around the guide pulley 6l and then downwardly andaround the pulley 47. The angular bracket 49 is shown in Fig. 2 as being carried on the bracket 62.

By referring to Figs. l to 3 inclusive, it will be clearly seen that, as the carriage 51 moves across the frame l1, during operation of the typewriter, the line spacing lever 50 slides on the cable 48 until it engages the knob 52, at the end of the movement of the carriage 5l, the swingingariii 58 remaining in its normal position, shown by full lines in Fig. VJhen the bar 34 is operated, however to actuate the lever 39 and pull the latter downwardly, the cable 48 is operated by the pulley 4T. This results in pulling the cable 48 over the carriage 51 and swinging the swinging arm 58 to its other extreme.

position, against the tension of the spring 60, as indicated by dotted line in Fig. 3. This results in the knob 52 operating the line spacing lever 50 and returning the carriage 5l to its initial position. Therefore, the operation of the line spacing mechanism and the carriage returning mechanism are performed by simply pressing the bar 34 downwardly with the thumb of either hand, without raising the hand from the flat key board. After the bar 34 is released, the spring 60 will act to automatically return the swinging arm 58 to its normal position.

rlhe Vspring 42 will also act to raise the levers 35 and bar 34 to their normal positions. The arms 43 and bars 45 serve to assure uniform movement of the levers 35 on the opposite sides of the machine, at all times.

The back spacer and marginal releasing mechanisms of the typewriter are operated by depending levers 63 which are adjustably carried on the outer ends of the rods 64 located at opposite sides of the machine and rotatable in suitable brackets 65 preferably carried on the inner face of the side members of the frame 10, as indicated in Figure 2. The rods 64 are located in planes above the rods 28 carrying the levers 32 and the depending levers 63' are located at the sides of the flat key board and slightly above the saine, so as to be operated by press` ing outwardly against the depending levers o23 with the hands, without the neceSSity of raising 'the hands from the proper position for operation on the Vdat key board. The rods (Si are shown as being connected by flexible connections {Si} with the respective levers lli ttor operating back spacer and marginal releasii mechan isms carrying appropr-lately marked keys i7 arranged in the upper key board. it apparent that, when the upper key board is dispensed with and the lower dat key board only employed, the rods (ill may have more direct connection with the respective n'ieohanisms operated thereby. y

ltis believed the complete construction and operation, as well as the advantage of the improved fiat key board and the associated parts will now be clear from the 'foie going paragraphs, taken in connection with the aecoin'isnying drawings, without further detail descVV ption. lt may bc briefly stated, however, that considerable speed may be attained by the operator, owing to the 'fact that the hands need never be raised troni the key board or moved up and down, during use oft the machine, except when the hands are confipletely removed for replacing-the paper in the machine. The operation of 'typing on the new i'lat key board is substantially the same as the operation ot playing the piano. Furthermore the keys are close together and all ot them are of elongated iform, thereby doing away with the spaces between the keys and around the same, as in the ordinary key board structure for typewriters. The keys are 'form-ed and mounted in such a manner that those required. for most tretpaent use may be readily operated by the iirst and second lingers ot the hands, while the other keys are in a position :tor easy operation by the other lingers and the thumbs. The dat key board may be readily incorporated in typewriters now in general use with very little additional expense and, as shown and described, is arranged particularly for portable typewriters. it is not necessary that the letters and other characters appear on the keys et the dat key board and, therefore such characters are only shown in the views disclosing the keys in order that the invention may be readily understood from the drawings and description. The operation oi' the spa er key may be readily performed by the vfirst linger ot either hand. Furthermore, the levers may be readily operated by the knees to actuate the shift keys, without the necessity oi' lifting the hands from the flat key board. rThe levers 63 may also be readily operated by an outward movement of the hands troni the fiat key board for operating the back spacing and marginal releasing mechanisms. All of the parts are o'l' simple construction, arrangement and operation and may be readw ily assembled.

It is apparent that, if desired, the usual torni of key board may be dispensed with and the improved ilat key board substituted therefor, when building up new typewriters. .ihis would naturali i inean that the shanks 18 would 'form continuations ot or replace the type bar operating levers 16, as shown in the drawings and the entire machine would be of compact construction.

'liihile the preferred embodiment et the invention has been disclosed.y it is to be understood that minor changes in the details ot construction, combination and arrangement of co-operating elements may be resorted to within the scope of what is claimed without departing from the spirit of the invention.
