PAOCKET TYPE-WRITER.

srnoIFIcATIoN forming part of Letters Patent No. 647,853, dated April 17, 1906.

Application filed October 9, 1899. Serial No. 733,083. (No model.)

To aZZ whom it may obi warn:

Be it known that I, EUGENE MCLEAN LONG, a citizen of the United States, residing at Washington, District of Columbia, have invented certain new and useful Improvements in Pocket Type -Writers; and I do declare the following to be a full, 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in pocket type-writers; and the object of the invention is to generally improve upon and render more efficient the invention upon which I have been granted Letters Patent in the United States, Serial No.

' present invention reside in the provision, in

connection with the fin ger-operated levers, of a thumb-operating lever which carries a type, adapted to be thrown so that said type will print in three different positions with reference to the vertical dash which is printed whenever any one of the finger-operated levers is depressed. By the addition of the thumb-key and type character carried thereby the invention is capable of short-hand work, as well as convenientffor a long-hand system.

My invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form part of this application, and in which-- Figure 1 is a perspective View of my improved pocket type-writer. Fig. 2 is a side elevation of the pocket-typewriter key. Fig. 3 is a rear elevation. Fig. 4 is a section on line 4 4. of Fig. 2. Fig. 5 is a sectional view on line 5 5 of Fig. 2. Fig. Bis a sectional view on line 6 6 of Fig. 2. Fig. 7 is a sectional view on line 7 7 of Fig. 2. Figs. 8, 9, and 10 are detailviews.

Reference now being had to the details of the drawings by letter, A designates the easing of my improved pocket type-writer, which may be of any convenient shape, preferably rectangular, and mounted on horizontal stubshaftsB and B. Supported by the framework containing the mechanism are the reels Gand 0, upon one of which, as O, aspool of paper D is placed and the other end passing over the reel 0, said paper being adapted to be wound from one reel to another as the characters are successively printed upon the same. Mounted on the stub-shaft carrying the reel 0 is a ratchet-wheel D.

Secured to the frame of the mechanism is a cushion-supporting bracket E, containing a rubber cushion E, against which the paper, inking-ribbon, and type are pressed in making impressions of the various characters.

. Journaled in the opposite longitudinal walls of the frame are the stub-shafts H, on which are mounted the levers K, which are preferably L-shaped and carry at their free ends,

the type K, which are utilized in making im pressions on the recording-strip D.

At each end of the frame are preferably mounted two of similarly-arranged keys, and about the shafts on which said keys are pivoted are coiled springs E, which are provided tohold the keys normally in horizontal positions, as shown in Fig. 1 of the drawings. For limiting the upward throw of said keys a cross-pieoeM is provided, against which the upper edges of the keys strike when returned to their normal position afterbeing depressed, as in the, act of printing a character on the strip of paper passed over the cushion. The faces of the type oneach of the levers are held in contact with one another, and their free ends are beveled for the purpose of allowing a dot to be printed when one of said type is depressed lightly against the paper and a dash printed should one of said type be depressed with more pressure, as will be readily understood. Each of these levers, which are of similar construction, have similarshaped type, each to be depressed by a distinct finger of the operator, and by depressing one or the other of these type a dot or a dash may be printed in any one of the four positions with relation to a vertical dash which is printed at each depression of any one of the four keys.

The type which prints the vertical dash is designated in the drawings by the letter Q and is integral with the pivoted member P, which is mounted on a pivot P, held to the frame containing the mechanism. This mem ber has akey Q extending slightlyabove the keys N,-whi ch aresecured to the levers K, and

pivoted to an extension of said member is a pawl R, the free end of which normally engages with the teeth of the ratchet-wheel D and is provided to cause a partial rotation to be imparted to the reel each time any of the I keys'N have been depressed and returned to their normal positions. A spring-pawl q'is secured to a portion of the frame and has its free end resting in contact with the teeth of said ratchet-wheel to prevent a backward rotation of the'same, and a spring G'is provided, which bears against the outer pivoted end of the extension of said member, to which the pawl is pivoted and adapted to throw thefforwardend, carrying the key that prints the On the reel F, mounted on the stub-shaft F,

carried by the frame, is coiled the ink-ribbon, which ribbon is passed over the guides F and wound upon the reel'J, which reel has a series' of depressions or recesses J, in' one of which a lug I, carriedby the ratchet-wheel I, which is mounted on the stub-shaft 1 engages,.said lug being provided toj cause the reel engaged thereby to rotate with the same. One of said keys K has its L-shaped end ex tended, 'as shown at K the end being re-' cessed, said recess being adapted to receive an 'arm 0, which is integral with the shaft 0',

mounted in the frame. Said shaft 0 has a second arm 0 to which is connectedone end of the pawl 0 adapted to engage with the teeth of said ratchet-wheel to cause a partial rotation to the ratchet-wheel and the reel car-' ried on the same shaft, which reelwinds upthe ink-ribbon, which is unwound from the reel mounted at the other end of the frame.

A stationary pawl 0 secured to the frame,

, engages wlth the teeth of the ratchet-wheel to prevent any backward rotation of the same. a

Mounted on the frame of the pocket typewriter is a lever T, which has a single character near its free end. This leveris mount- 1 ed between the walls of a portion of the frame, bentupon itself, said walls serving as, a guide as the lever is tilted backward andforwardl The portion of the lever carrying the character of any shape desired is spring-actuated, being formed out of a portion of said lever or secured thereto, and is normally held in the Y d pe carrylngportion of the lever is made spring position shown in the drawings.

actuated, so .as to yield when any one of the levers carrying the type which are actuated the strip of paper as any one of the finger-op eratedkeys is depressedfsaid character being printed in any one of the three positions with relation to the dash which is printed vertically across the strip of paper. Normally the charactercarried by the spring portion of said lever is held out of the-path ofthe type which are depressed by the-fingers of the operator. Said character carriedby the spring part of the lever described is adapted to be operated by the thumb of the operator, a suitable thumb-key W being secured to the free end of said lever andextending through the casing and in convenient position to be engaged by the thumb as" the instrument is held in the'palm of the hand in a natural way. In order to determine in which position the thumb character is to be printed .by the ac- .tuation of the thumb-key,a series of three notches is provided in the slot through'which the thumb-key passes, and the th umb-key is so constructed-that the thumb of the operator, by feeling, may determine which notch said key is opposite previous to the depression of any one of the finger-keys in the act of printing the characters. A coiled spring V, secured at one end to the frame, its other end fastened. to the thumbdever, is provided to' hold the character carried by the thumblever normally out of the paths-of the type carried by the finger-operating keys 7 In pe n whe t is s t p in any character by means of the finger-actuated keys any key is depressed, and with it the 'member having the type-face printing the vertical dash. When it is desired to print a character controlled by the thumb-key, said thumb-keyis'adjusted by pushing. it down in the slot in-the casing until said key'is held in one of the three notches provided to determine which position the character on said lever is to be printed, and then one of the finger-operated keys is -depressed, which will 1 cause thecharacter on the thumb-lever to be printedin one of the three positions relative to the vertical dash. At each depression of the k'ey which isconnectedto the feeding mechanism onthe ink-reel said reel will be given a partial rotation, causing the ribbon to wind from one reel to another, and at each depression of thefinger-keys after an impres sion has been made the paper is wound from one paper-reel to another. If-it is desired for any purpose to feed the strip; of paper forward without printing, the same can-be done by depressing the key which is integral with the rack carrying the Vertical dash, without depressing any one of thefinger-keys.

B y this arrangement of type I am' enabled 1 to print three hundred and twenty-four difierent symbols, thus enabling me to provide a i system whereby stenographic, as well as longhand systems, may beequally-well recorded. byjthe finger-keys is depressed against the upper face of said spring portion of the lever carrying thetype, and" the device is 5 so ad r justed that the characterwillbe'printedfupon T ?ters Pa en 1.
