TYPE-WRITING MACHINE.

i SPECIFICATION forming part of Letters Patent No. 364,556, dated .Tune 7, 1887.

Application filed January 28, i886. Rent-wed February 9, 1897. Serial No. 227,092. (No model.)

To LEZ whom -i may concern.-

Be it known that I, FRANZ X. WAGNER, a citizen of the United States, residing at New York, inthe county and State of New York, have invented new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates to improvements in type-writing machines; and it consists in the combination of certain parts, all of vwhich are more fully pointed outin the following specification and claims, and illustrated in the accompanying drawings, in which- Figure l represents a horizontal section in the plane @o m, Fig. 2, of a typewriter con structed according to my invention. Fig. 2 is a vertical transverse section of 'the same in the plane 3/ y, Fig. l. Fig. 3 is a front elevation thereof,showing the mechanism for adjusting the type-carrier so as to bring either of the rows of type into the printing-line,and

of the adjacent parts. Fig. 4 isa pla'n viewV of the device for rotating the type-carrier so as to bring an'individual type into the print ing-line. Fig. 5 is a rear elevation of the earriage-feeding mechanism. Fig. 6 is a sectional elevation of the mechanism for imparting to the platen a motion toward and from the'typecarrier.

Similar lettersindicate corresponding parts.

In the drawings,the letter A designates the base-plate of the typewriter, B, the type-car-V rier, whichis shown in the form of a wheel and has arranged upon its periphery one or more horizontal rows of type.

C is the platen, Figs. 2 and 6, which `has journal-bearings in the side levers,D D, of the platen-carriage. The said platencarriage can swing about a bar, d, to-which it is hinged at cl d. A pressure-roller, cl2, having slot-bearings and clamps d3, together with the usual ratchet-wheel and pawl, (not shown in the drawings) are provided as means for holding and feeding the paper, and may be of any well-known construction. Across the side levers,D D, and secured to the arms d4 thereof, is a tierod,d5,which is engaged by a lever,D, which is secured to a frame, D2, that can turn on a shaft, D3, having bearings in lugs a of Itis obvious that when this lever D' is ydepressed the platen-carriage is caused to turn about the bar d as a fulcrum,

and the platen C is moved toward and brought in Contact with one of the type on the type' carrier B, and when the said lever D is released the platen-carriage will fall back from its own weight. To return the lever D toits normal position it is subjected to the action of a spiral spring, Dt.

The type-carrier B is mounted to rotate about a hollow shaft, E, and can also be adjusted vertically thereon, the first movement being essential to bring each type into the printing-line and the second movement to bring each row to the level of the printingline. i

To rotate the type-carrier, and at the same time to provide means for depressing the platen-lever D', so as to vibrate the platen, I employ a key, F, having a shank, f, which eX- tends downwardly through the hollow shaft E and impinges upo'n the said platen-lever, and is supported thereby. From the shankf of the key extends a horizontal arm, which is provided with a pin,f, that engages with a -s1ot,f2, in an arm or web,f, of the typecarrier B,so that by rotating the key F the typecarrier B is rotated, and by depressing the said key the platen G is brought against the type-carrier through the medium of the lever D. To facilitate the manipulation of the key, the shank f is provided with a knob and plate, which are attached to its upper end.

Pendent fromV a hinged lid or cover, K, is a guide-plate, G, containing a series of notches or guides, g, on .its periphery, and upon the upper surface of the lid or cover is arranged an index-plate, H, which bears the letters, arranged in alphabetical order, and also the numerals, punctuation-marks, and other signs which may be found in the type on the typecarrier. From the key F extends a pointer or index-hand, I, Figs. 4 and 6, in the same plane with the index-plate.

The notches or guides g in the guideplate G taper downward, andthe key F is provided with a tooth, ft, which engages one of the notches or guides in the guide-plate when the ICO rectly above the guides g, and therefore, when the key is depressed after rotating the same to the desired letter, as pointed out on the index-plate, this tooth will enter 011e of the corresponding guides, and the desired letter is guided to and held firmly in the printingline.

J J, Figs. l, 2, and 3, are the inking-rolls, which are mounted so as to be capable of' rotation upon vertical arbors j j, Fig. 1, which are secured in the arms 7" j' of supports J', swiveled upon a bracket, J, that is provided with a sleeve, and said sleeve is fitted to the hollow shaft F. rlhe bracket J2 can be shifted vertically upon said shaft and is guided by a post,j`l, secured in the base of the shaft E. To hold the inkng-rolls in contact with the types on the typecarrier, a flat spring, J, is secured to the brackets at its center, and the ends of this spring are in contact with arms j j" of the supports J When the rows of type are arranged upon the type-carrier, as in the example shown in the drawings, the center row, which, for convenience, contains the small letters of the alphabet, is arranged in thelevel of the print ing-line, and one of ils types produces an impression when the type-wheel is in its normal position, as shown in full lines in Figs. 2, 3, and 6. To obtain an impression from the remaining two rows of type on the paper carried by the platen, it is necessary that the type-carA rier B, together with the ink-rolls J J, should be respectively raised or lowered through the proper distance to bring the respective row of type in the position previously held by the center row of type. For this purpose the bracket J2, upon which the typecarrier also rests, is carried upon an inclined cam, L, secured to or formed integral with an arm, Z, Figs. 1, 2, and 3, which extends from a frame, L', that can rotate about an arbor, L?, so that when the said cam is swung radially about its points of` pivoting theinkrolls and type wheel are elevated, or vice versa.

The arbor U is supported at its bottom in the base-plate, while its'top is restrained in a bracket, M, which is supported upon two standards, m m'. A spring, L, which is coiled about the arbor L2, tends to hold the frame in a definite position. To this bracket M is also hinged the coverK, previously referred to.

From the frame L' extends a movable fingerpiece, N, which is arranged centrally between two stationary thumb-pieces, N' N 2, which project from the standards m and m', respectively, and serve as a stay for the hand in moving the iingeepiece. XVhcn the finger-piecc N is in its normal position, the center row oftype is in the printing-line. Then the same is drawn against the thumb-piece N', the bottom row of type is in the printing-line, and when the fnger-piece is against the thu mb-picce N2 the top row of type is in the printing-line, the typecarrier being always returned to its normal position by the action of the spring L".

In order to obtain the necessary space between thc consecutive letters, a rack, O, is secured to the back of the baseplatc, which is engaged by a gravitating spacing-dog, O', that is carried by an arm, 0,which extends from the frame of the platen-carriage,- Figs. l, 2, 5, and G. The spacing-dog O' is provided with teeth o' o2, one at each end, and is pivoted to the arm 0 at the point between the teeth c o, but nearer the tooth o2, so that when the spacingdog is free to move, it turns about the arm o and the portion carrying the tooth 0' moves toward the rack. When the platen is moved in its vibratory motion toward the type-earrier by the depression of the key F, the spaeingdog is immediately raised and the teeth o' 0'; are cleared from the rack; but during such elevation the said dog turns about the arm o, as above stated, and consequently the tooth o' is brought into the position shown by dotted lines in Fig. 5, or one tooth in advance. YVhen the platen falls back from the type-carrier on release of the key F, the dog is carried with the same and now turns about tooth o' as a fnleru m to the position shown in full lines in Fig. 5, and consequently the carriage has been advanced a distance equal to the pitch of the teeth on the rack.

To obtain the space between two consecutive words, a spring-pressed stop-rod, It, is arranged in bearings r in the base'plate A, having at one end a button, while its other end is in a proper position to extend under the lever D' when the latter is in its raised position, as shown by full lines in Fig. 2. If the stoprod It is pushed inward, so as to extend under the lever D', and the key F is depressed, the lever D' comes into contact with the stop-rod, which Varrests its motion, so that the platen y, although moved sufficiently to aetuate the spacing'deviee, does not come into contact with the type on the type-carrier. The paper-earriage, however, moves sufficiently to advance the carriage by one tooth, whereby thc desired space is obtained.

To return the carriage after it has arrived at the end of ifs travel, a clearing-lever, S, Figs. 1 and 2, which is secured to the rockshaft D, actuates a flat bar, S', which lbar is in position to engage with a pin, s, upon thespaeing-dog O, thereby lifting the same out of engagement with the rack. The type-carrier, instead of being in the form of alwheel, may be a segment. To replenish the inking-rolls J J, which are covered with any material which soaks up the ink, it is necessary to remove the same,which is done by opening the hinged cover or lid and then removing the key F and the typeearrier B, when the rolls can be lifted out, together with their lever-supports, or the entire roll-bracket may be removed. To preventthe inopportune falling ont or removal o1' the key, a small lateral projection, h, is formed on the pin f',which extends inwardly beyond the base of the teeth, Fig. 2, and to remove the key it is necessary to move the same to a recess, h', Fig. 4, in the guide-plate G. A latch, T

pivoted to the lid or cover, is provided to close access to the recess and to limit the sweep of ICO the key, and consequently the rotation of the type-carrier. y

To render the adjustability of the-type-car rier B in ahorizontal plane more accurate, the thun1b-pieces N N2 are each provided with adj Listing-screws a n2, against which the fingen piece N impinges.
