FRANZ X. XVAGNER, OF NEV YORK, N. Y.

TYPE-WRITING MACHINE.

SPECIFICATIONforming part of Letters Patent N 0. 454,692, dated June 23, 1891. Application filed December 19, 1889. Serial No. 334,294 (No model.)

To all whom it may concern.-

Be it known that I, FRANZ X. WAGNER, a

citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Type-Vriting Machines, of which the following is a specification.

This invention relates to improvements in type-writing machines; and the invention consists in certain details of construction set forth in the following specification and claims and illustrated in the accompanying drawing, in which- Figure 1 is a front elevation of a typewriting machine. Fig. 2 is a rear. elevation of Fig. 1. Fig. 3 is a plan view of Fig. 1. Fig. 4 is a section along a: a", Fig. 5. Fig. 5 is a side elevation of Fig. 1. Fig. 6 is a section along y y, Fig. 1. Fig. 7 is a side elevation of arms which assist in the motion of certain parts. Fig. 8 is a detail View of the spacingkey and contiguous parts.

In the drawings, the letter A indicates a suit able base or support.

The platen or paper-carrier B may be of any suitable well-known construction, adapted to travel along and swing on the guide-rod O, and being also supported by a roller or wheel D, traveling along a suitable track E. In the drawings the platen B is shown mounted in a carriage, the essential parts of which may be of any well-known constructionas, for example, a back or back plate E, Fig. 6, having arms or lateral frame-plates S, through which the axle of the platen passes, and from the back R extends an arm T, on which is mounted the wheel D, and said back R also has arms or lugs U, which are perforated for the reception of the guide-rod C, so that the carriage with the platen can swing and travel on said guide-rod. A spring-drum F, con nected to the platen by a strap or band G, may be used in connection with a rack H and feed-dog I to feed the platen.

The type are supported by a carrier, wheel, or cylinder K. Said carrier K is capable of a rotary motion, by which the required type is brought opposite to the platen, and of a linear or printing motion, by which the carrier brings the required type against the platen, so as to print. Said type-carrier may also have two or, more rows of type, in which saidkeys when depressed by the operator imparts motion to a bell-crank lever N O, fulcru med at P, there being one bell-crank lever for each key. Each arm N of the bell-crank levers has a lug or shoulder V, Fig. 3, which extends under the. key L, so that the key rests on said shoulder V and arm N, so as to move the bell-crank lever N O. The depression of a key moves the corresponding bell-crank so as to swing its arm 0 backward or toward the platen B. The arm 0 is extended up far enough to strike the actuating-bar Q, Fig. 7, so that the backward motion of the arm 0 is communicated to the actuating-bar Q, from which an arm R extends to the slide S, so that said slide moves with the bar Q. The arm R is rigidly fixed to the bar Q, so as to move with the same. Said bar- Q is supported by arms T, fulcrumed at P, and said arms T are extended so as to form lugsU for the support of the bar V, to which an arm W is secured. The arms T may be fulcrumed at any'convenient point along the shaft P. In the drawings the arms T are shown arranged in two sets, one set on each side of the type-carrier and having three arms T in each set, one. arm

of said set being located near the outer part of shaft P, another arm being located near the type-carrier, and the third arm being intermediate to said two arms. To the arm W is connected the restoring spring X, and when the depressed key is released the restoring-spring X moves the key with the actuating-bar Q and slide S to the starting position. The slide S has teeth or grooves Y, which engage lugs Z, connected to the toothed wheel a, fixed to the axleb of the type-carrier K. Each slide S is supported by a pivot WV, connecting the slide S with one" of the arms R, and by a pivot X, fixed to a suitable part of the frame. The slide S, as shown in the drawings, can be readily formed froma piece of sheet metal suitably bent and shaped or cut to form the teeth Y and provided with a slot for the reception of pivot X, as seen in Figs. 5 and 6. When the slide S is moved toward the platen, the teeth Y rotate the lugs Z and type-carrier K, so as to bring the type corresponding to the moved key opposite to the platen, so as to be ready to print. The return of the slide S restores the type-carrier to its starting position.

For different types the carrier must rotate more or less to bring said type opposite the platen. For this purpose the arms N of the leversN O are of varyinglengths. The longer arms N, being in contact with the keys L nearer to the fulcrum M, will not receive so great a degree of motion from the depression or swing of the keys as the shorter arms N, which, being in contact with the keys L, farther from the fulcrum M, receive so much more motion from the swing ofthe keys on the fulcrum M. The greater or less motion of the various arms N and levers N 0 causes greater or less motion of the slide S and consequent variety in the rotation of the typecarrier K. When the rotation of the typecarrier has ceased, said carrier is given a linear or printing motion to carry the required type against the platen, so as to print. To give this printingmotion, the following mechanism is employed Links 0 extend across the machine, there being one link for each'key L and lover N 0. As seen in Fig. 7, each link a is made to extend across the frame A, so as to be supported by said frame, said frame having slots or recesses, Fig. 1, into which the links 0 are set and in which said links are guided. When a lever-arm O swings backward, a pin 61 on said arm 0 presses against alifting shoulder or incline 6, Figs. 5 and 6, on the link 0 and raises the link, so as to bring the connecting-shoulder f on said link in the path of the actuatingbar Q. As the actuating bar moves back it strikes against the shoulder f and forces the link backward. As each link 0 is made to abut against the printing-bar g, Fig.7, this backward motion of the link is imparted to said printing-bar g, which is connected by a link It, Figs. 5 and 6, to the axlebof the typecarrier, so that the backward motion of the printing-bar is communicated to the typecarrier to give the printing motion to said type-carrier. To the printing-bar g are fixed one or more arms Y, Fig. 7, to which the link h is connected by a pivot Z, so that the link It partakes of the motion of bar g.

As the printing motion of the type-carrier consists in the type-carrier moving backward toward the platen, and during such printing motion of the type-carrier the slide S and the type-carrier move backward simultaneously, said slide during the printing motion of the type-carrier will not rotate said carrier.

'As the type-carrier must rotate more or less to make different types face the platen, the connecting-shoulders f of the various links 0 are placed farther from or nearer to the starting-point of the connecting-bar Q, so thatthe connecting-bar will not move a link 0 to give the printing motion to the type-carrier until the proper type on said carrier faces the platen. That link 0 which is to be actuated, as already stated, is raised by the pin 01 and incline 6, so as to lift its connecting-shoulder into the path of the actuating-bar Q, while the links which are to remain at rest are not raised, so that the bar Q swings over said links without imparting motion thereto. The printing-bar g is supported by arms t', fixed to a shaft 76, swinging on the frame or support, and from the shaft extends an arm Z, Figs. 2 and 6, to which is secured a restoring-spring m to restore the printing-bar and the links 0 to the starting-points at the proper moment. The printing motion of the type-carrier should not occur until the proper type faces the platen. To prevent such printing motion at improper moments, a stop it, Figs. 5 and 6, is provided, which prevents the printing motion of the link h and type-carrier K until the proper time. This stop 11., as seen in Figs. 4, 5, and 6, when in its normal position, projects up through an eye or perforation in the link 71, so as to prevent said link sliding backward. W hen the printing motion is to occur, the stop n is withdrawn. This stop it is connected to a universalbar '0, Figs. 4, 5, and 6, and as a key L is depressed said key presses on the universal bar 0 to withdraw the stop it. The connection between the stop n and bar 0 is readily formed by providing the bar 0 with a nose 0., Figs. 5, 6, and '7, which nose projects into or passes through an eye or perforation in the stop it, so that the descent of the bar 0 will depress the nose 0. and withdraw the stop it. When the key is released, a restoring-spring, Fig. 6, carries the stop back to its locking position. This restoring-springp is shown in Figs. 6 and 7, and as the stop or and bar 0 are connected, as described, the return of the stop by the spring 19 will return the bar 0 to its normal position after being depressed.

The stop it is provided with an arm (1, connected by a pin 0" with an arm .5, con nectedto the feed-dog I, so that the oscillations of the stop n oscillate the arm 3 and actuate the feed-dog. The feed-dog is mounted on the pivot b, Figs. 2, 5, and 6, and said feed-dog may be of any suitable well-known construction. In the drawings the feed-dog is shown composed of two blades I, slightly separated or out of line with one another, as seen in Fig. 4, and as one of said blades passes out of gear with the rack H and the other blade passes into gear with said rack the platencarriage moves or slips along a slight distance, sufficient to form a space between two letters.

During'the printing motion rotation of the type-carrier is to be avoided. For this purpose a stop If is fixed in position to be engaged by the toothed wheel a, fixed to the type-carrier shaft b, when said shaft 1) moves the type-carrier toward the platen B. while the toothed wheel a is in engagement with the stop t rotation of the type-carrier is prevented. When the type-carrier, with its shaft 1) and wheel a, moves back to the startingpoint, the wheel a is carried clear of the stop If, and the type-carrier is again free to rotate.

The universal bar 0 is supported by swinging arms u, swinging on the fulcrum M. Said universal bar 0 is shown as having one or more arms '21, Figs. 3 and 4, from which extend pins w, on which press arms A, extending from the arm T, Fig. 7, so that the arms T A in each case form a bell-crank lever. As the bell-cranks T A are moved by the backward swing of the actuating-bar Q, the arms A depress the pins 10 and arms'v, so as to depress the universal bar 0. The return movement of the universal bar by means of the arms A '0 assists the return of the actuating-bar Q to its. starting-point. As the arms A, in connection with the arms T, form a bell-crank lever, and as the bar Q is connected to the arm T, the return movements of the arms A will cause the arms T and bar Q to return to the starting point.

The type-carrier K is inked by the inkingrollers B, pressed against the carrier by spring-arms C. The arms C1 are supported by an arm D, which, with the type-carrier shaft 1), has a common support E. The arm D has lateral arms 0, to which the springarms 0 are connected by pivots d, and to said arms 0 are soldered or fixed lugs c, Fig. 5, which lap over the arms 0 to prevent excessive outward motion of said arms 0 and to hold said arms 0, with their rollers 13, against the type. The support E is simply a rod or bar fixed to the arm D and to a sleeve or tube f, in which the shaft 6 is supported, and in which it can rot-ate. The arm D is guided in rising and falling by a screw or stud g, fixed to a frame A and passing through a slot in the arm D, Fig. 1. The lower end of shaft 1) is supported so loosely in the bottom of sleeve f that the upper end of the shaft has enough freedom for lateral motion to move the type-carrier against the platen. The sleeve f is guided in its rising and falling motion by suitable perforations or ways in the frame A. By making this support E capable of rising and falling or an axial modon-that is to say, a motion in the longitudinal direction of the axle or shaft b-the typecarrier can be raised and lowered, so as to bring different rows of type into the printing line.

A lever F, fulcrumed at G, can be made to raise the type-carrier. This lever F, as seen in Fig. 1,has one arm passing under the support or rod E, so that the upward swing of this lever-arm will raise the support E, together with the shaft b and type-carrier. This lever F can be actuated by a finger-button H, attached directly to the lever F or by a key I, made to act on the said lever. The

- key I is shown fulcrumed or pivoted to the frame A at 7i, Figs. 3 and 4E, and said key passes over or rests upon the lever F, so that the depression of the key will swing the lever. In practice it will be found convenient to arrange the key- I so as to actuate the lever F to'a certain degree to bring one row of type into the printing-line and to arrange the finger-button H so as to actuate the lever F to a different degree to bring another row of type into the printing-line. When the lever F is released,'a restoring-spring K brings the lever F and the type-carrier K back to the starting-point. The lugs Z on the toothed wheel a of the type-carrier shaft 19, are so long that the rise and fall of the shaft 12 does not disengage the lugs Z from the slides S.

About the platen B pass flexible bands L. One end of each of said bands is secured to the supporting-frame of the platen, and'the other end of each of said bands is secured to a spring M, seated on a bar N, supported by the supporting-frame of the platen. The springs M. hold the bands L snuglyagainst the platen. The springs M, as seen in Fig. l, are coiled about the bar N, and one end of each spring is secured to a stud 11, fixed to said bar, and the other ends of the springs are secured to armsk, swinging on said bar N, and to which arms the free ends of the bands L are secured. The tension of the springs causes the arms k to pull on the free snugly about the platen. When a piece of paper is passed onto the platen, the edges of the paper come between the platen and the bands L, so that said bands hold the paper snugly against the platen.

The spring-drum F for moving the platen is shown as having its axle 0 extending through the machine, so that said axle has a firm seat, andsaid axle can be provided with .a ratchet and pawl in any well-known way to enable the spring of the drum F to be put under proper tension.

In addition to the restoring-sprin gs already ends of the bands L and to draw said bands IIO named, each key L can be provided with its 7 individual restoring-spring P. In Figs. 4 and 5 the springs P are shown coiled about the fulcrum or bar M and having one end braced against frame A and the other end passing under a stud Z on the key, so that the tension of the spring presses the key upward. The keys L are shown arranged in two sets, one set on each side of the type-carrier K. Each set of keys acts alike in rotating the type-carrier and imparting motion thereto, and each set of keys is provided with its actuating-bar Q and slide S. One slide S rotates the typecarrier in one direction and theother slide S rotates the type-carrier in the opposite direction.

The spacing-key Q is made to actuate the universal bar 0 so as to actuate the feed-dog I, and, if desired, said spacing-key can. also be made to rotate the type-carrier, so as to see cure inking of said carrier; but said spacingkey should not be made to actuate theprinting-bar 9, so that during the spacing operation the type-carrier does not have any printing motion. The spacing-key can readily be prevented from actuating the printing-bar, since by not providing any linkcfor the spacing-key said key cannot communicate motion to the printing-bar. The spacing-key is mounted on fulcrum M, and is made to pass over and press on the universal bar 0 the same as any one of the keys L, and by providing the spacing-key Q with its bell-crank lever N 0 said key Q when operated will actuate the bar Q and rotate the type-carrier the same as a key L.
