T0 0% whom it may concern/.-

Be it known that I, ERNST SENSBURG, a subject of the King of Bavaria, residing at Munich, Kingdom of Bavaria, Germany, have invented certain new and useful Improvements in Type-Writers, of which the following is a full, clear, and exact description.

My invention relates to improvements in typewriting machines.

The object of my invention is to provide a type-writing machine which while reasonably compact will permit of the use of a larger number of type than usual, so that not only letters may be printed at one stroke of a key, but also syllables and words such as are in common use.

With this object in view and some others which will be obvious to those skilled in the art a machine embodying my invention comprises a plurality of type bar carriers or frames mounted on a carriage, each provided with a plurality of type-bars, each of which type-bars carries a plurality of type, means being provided for positioning the type-bar carriers with relation to the printing-point and for positioning any desired type-bar of the positioned carrier, whereby the desired type on the type-bar is brought to the printing-point. Any suitable paper carrying and feeding mechanism may be employed and also any kind of spacing device or printing mechanism.

My invention will now be described in connection with the drawings and then particularly pointed out in the claims.

In the drawings, Figure l is a side elevation of so much of a machine embodying my invention as is necessary to illustrate the said invention; Fig. 2, a plan view of the same; Fig. 3, a detail perspective view of one of the type-bar carriers or frames with the typebars, showing also a part of the means for positioning the type-bars.

Referring to the drawings, 1) b b b indicate a plurality of type-bar carriers or frames (in the present case four in number) mounted in a carriage B, movable along a track B. Each frame or carrier 1) b b b is provided with a set of type-bars, each set consisting of a plurality of movable type-bars, in this instance three in number, as indicated at a a? a Fig. 3, each of which has a plurality of type, as indicated at a, Fig. 3. The typebars a a a are mounted to move in the respective carrier in the direction of their own lengths, for example, by providing slots in the frame in which the said type-bars lie, the said type-bars being held in the slots in a mannerto permit of their longitudinal movement by any suitable meansas, for example, by undercutting the slots and making the type-bars of a corresponding cross-section, so that theywill properly fit said slots. The sets of type-bars are so arranged in their respective frames that the axes of the typebars of each set will intersect at the printingpoint. For example, in the structure shown in Fig. 3 the central type-bar a occupies a vertical position, while the two outer typebars a a are each arranged at an angle to the central type-bars, so that the axes ofthe type-bars would intersect at the point at, Fig. 3, which is the printing-point. By this construction any desired type on any one of the type-bars may be brought to the printingpoint by moving the proper bar in the direction of its length for a suitable distance. Furthermore, by moving the carriage B, containing the frames 1) to 19*, in the proper direction and to the required extent any desired set of type-bars may be brought into the plane of the printing-point, whereby any desired type of any type-bar in any of the various sets may be positioned for printing. In the machine under consideration the normal position of the type-bars a a a 'is with their upper ends below the printingpoint, and hence in order to position a type for printing the bar carrying the desired type must be elevated. Therefore in the present machine I provide means for moving the carriage B and means for elevating the I typebars. The preferred mechanism for doin this will now be described.

The carriage B, Fig. 'l, is connected ina suitable manner to the upperend of a lever e by means of a pin 6, secured to the carriage, which pin enters a slot in the end of the lever e. The latter is fulcrumed on the frame, as at 6 and is arranged to be moved in any-suitable manneras, for example, by a treadlelever E, connected by a link E to a bell-crank E which is joined by a rod E to thelower end of the lever e.

ing rods.

socket joint (indicated at S, Fig; 3)each rod being forced outward at an angle by means of a spring a a U3, secured at one end to its.

respective rod and at the other end passed loosely through a staple R on the end of the type-bar. In order to prevent the springs u 11. n from forcing the rods outward unduly and to insure the normal retention of the rods at'a predetermined angle to the type-bars, suitable stop devices are provided, these consisting, preferably, either of a loop secured to the type-bar, as shown at t in Fig. 3, or of fingers t 25 which are secured to the respective type-bars and extend over the correspond- By this means the lower ends of therods r r r may beheld in a line with each other. The said lower ends are arrangedto be engaged by suitable lifting devices--as,for example,the key-levers o 0 0 -each of which is fulcrumed in the frame, as indicated at 0, Fig. 1, and is provided with a socket 0, arranged to engage a ball on the lower end of the corresponding lifter-rod.

For the purpose of operating the levers 0 0 0 the predetermined extent necessary to bring the various types to the printing-point a number of plunger-keys p 19 19 Fig. 2, are provided, these keys being preferably arranged in banks, as shown in Fig. 1, each bank being at a different distance from the fulcrum of its corresponding lever 0 0 0 each lever being provided with lateral arms g, which are engaged by the key-plungers point and opposite the latter. The said pa-' per rolls and rollers are mounted on any suitable carriage, as indicated at f, Fig. 1, capable of movement across the machine in the normal way. Any desired form of ink-supplying mechanism may be provided, and the printing, which is done by striking the paper against the inked type or against an inkingribbon interposed between the type and paper, may be accomplished by any suitable mechanism such as is well known in the art. For example, I have shown a longitudinallymovable rod m arranged to strike the paper against the type, and thereby produce an impression, which rod m may be moved at the proper time in any suitable way.

The operation of the machine just described is as follows: The operator ascertai'ns by inspection upon which keyboard is Located the key for the character desired to be printed and then presses the treadle-lever to the extent necessary to bring the frame or carrier containing the type for such character to the plane of the printing-point. He then presses down the proper key, and thereby elevates the corresponding type-bar, the motion transmitted from the key to the type-bar being just sufficient, when the key is fully pressed down, to bring the desired type to the printing-point. At thismoment the rod m is operated to force the paper against the positioned type, whereby an impression of the desired character is made upon the paper. Succeeding characters are printed in the same way, it being understood that the paper is fed in the proper direction and to the required extent by suitable mechanism at the proper time.

As each key serves to position a series of type-barsviz. one type-bar on each frame and as each of said type-bars is intended to carry different type, it is clear that each key will serve for positioning a plurality of type characters. Hence it will be preferable to have each of said characters which a key will position marked on said keys. One key so marked is shown on the middle keyboard in Fig. 2.

While I have described and shown a machine having four type-bar carriers or frames, each of which is provided with three typebars, it is to be understood that I do not limit my invention to these specific numbers of carriers or type-bars.

- Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a type-writer, the combination with a plurality of type-bar carriers and type-bars bodily and vertically movable therein, each type-bar having a plurality of type, of means for moving the carriers to the plane of the printing-point, and means for moving the type-bars relative to the carriers to bring the desired type on the type-bar to the printingpoint.

3. In a type-writer, the combination with a plurality of type-bar carriers, and a plurality of sets of type-bars, one set movably mounted in each carrier, the type-bars of each set being so arranged that their axes will intersect at the printing-point, of means for positioning the carriers and means for positioning the type-bars.
