TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 690,210, dated December 31, 1901.

Original application led November 11, 1899, Serial No. 736,587. Divided and this application led September 28. 1900.

Serial No. 31,365. (No model.)

To a/ZZ whom, t may concern:

Be it known that I, HERMAN L. WAGNER, a citizen of the United States, residingin the borough of Brooklyn,county of Kings,cityand State of NewYork, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates to type-Writing machines; and the principal object of said invention may be generally said to be to provide a simple and eiiicient mechanism for operating the type-bars and the carriage mechanism.

In the accompanying drawings, Figure I is a longitudinal sectional View from front to rear of a sufficient number of parts of a typewriting machine to illustrate my invention. Fig. Il is a detail side View of a modified form of type-bar,together with its cooperating slide. Fig. III is a fragmentary detail view, partly in section, of the type-bar.

The subject-matter shown and described herein constitutes features which were divided out of my application,Serial No. '7 36,587 iiled November 1l, 1899.

The main frame 1 ofthe machine has mounted therein a segmental plate 2, that has radiating slots 3 therein, in which slots the various type-bars 4 are pivoted upon a single rod 5, which is properly supported in place upon the segmental plate 2. The type-bars 4. are each provided with a slotted or doubled portion 6, by means of which the type 7 8 may be brought nearer to or forced farther from the pivot of the type-bar for the purpose of alining said type. Thus, for instance, a lateral compression of the doubled portion of a typebar will cause the type thereon to be forced farther from the pivot, While a lateral expansion of said doubled portion Will cause said type to be brought nearer to the pivot of the bar. Each of said type-bars is provided with a transverse opening. at its end, as indicated in Fig. III,for the reception of a conoidal stem 9, carried by the type-block 10. The opening in the type-bar should correspond, substantially,in form to the conoidal stem on the typeblock. It will be observed that the stem 9 is in line with one of the type (8) on the typeblock, so that the impact of said type on the platen will be in line with the stem instead of to one side of the point where the type-block is connected to the type-bar, as heretofore. It will likewise be observed that an end type on a type-block is in every instance in the same plane as the body of the type-bar to which the block is connected, irrespective of the position to which the block is `adjusted in the opening for the stem 9. It will be understood that the typer on everytype-bar except the center one extend in a line drawn at an angle to the plane of the type-bar carrying said type. I am thus enabled to employ type-bars which are straight throughout their lengths, or, in other Words, which are Without the lateral bends that are usually employed in type-bars used in front or top strike type-writing machines. The advantage of astraight type-bar is that it can be made of heavier stock, and, furthermore, there is no liability of the bar being deflected out of its course by centrifugal force in the movement of the side bars toward the printing-point, as is the case when typebars having lateral bends are employed in such machines. Furthermore, by this construction the type can be quickly adjusted and are not so liable to get out of alinement as type-bar constructions employing a plurality of type on a bar, as heretofore used, and there is no necessity forbending the body of the type-bars laterally in order to secure proper alinement of the type.

Referring particularly to Fig. I of the drawings, it willbe observed that each of the typebars is provided at the heel thereof with a plurality of teeth, the teeth 1l being nearer the pivotal axis of the type-bar than the teeth 12. These teeth are adapted to coperate with teeth 13 14, carried by a reciprocating slide 15, one of such slides being provided for each type-bar. It will be observed that by this construction a reciprocating motion irnparted to one of the slides 15 will cause the corresponding type-bar to be moved around its axis, and the movement of the type-bar will be graduallyaccelerated as it approaches the printing-point by reason of the gradual change of leverage.

Another form of type-bar and means for imparting movement thereto is illustrated'in Fig. Il of the drawings, wherein a slide 15 and a type-bar 4, pivoted at and having a type- 5 block 10, are employed, as in the construction previously described. In this last construction, however, a laterally-projecting pin 16is carried upon each of the slides and engages in an elongated slot 17 in the coperatng 1o type-bar Ai. Each of the slides 15 may be operatively connected to an arm 18 of a keylever 19 by a pin-and-slot connection. The pins may be carried upon the slides, as represented in Fig.V I, or upon the arms 1S, so as to cooperate with a slot in each of the slides,

as represented at 20 in Fig. II of the drawings. The key-levers 19 are provided with finger-keys 2l and with notches 22, which permit them to be seated upon pivots 23, carzo ried by studs 24, secured to a bed-plate 25, connected to the framing ot' Ithe machine. Each of the slides 15 is supported and adapted to slide in the ways formed in the segmental plate 2 and the segmental support 2G, and the z5 rear end of each of these slides has a hooklike portion 27, which permits each of the slides to move rearwardly independently of a suitably-supported segmental universal bar 28 with which the slides cooperate. A forwill canse the universal bar to be moved forward with it. This universal bar 28 is connected in any suitable manner with the feed mechanism (not shown) for the carriage 29.

By this arrangement it will be observed that a depression of any of the finger-keys will cause a forward movement of the corresponding slide l5, and motion will be transmitted to the universal bar to move it forward independently of the remaining slides and 11o efward movement, however, of any of the slides feet a movement of the spacing mechanism, which, as before stated, is operatively connected to the universal bar.

It is thought that from the foregoing description the operation of the parts will be understood and that no further detail description of the operation is necessary.

Having described my invention, what I claim, and desire to secure by Letters Patent, is- 5o 1. In a type-writing machine, the combination ot' a type-bar, a reciprocating slide and a connection between said slide and type-bar which connection effects a gradual change of leverage during movement of the type-bar by 5 5 the slide to and from the printing-point.

2. In a type-writing machine, the combination of a pivoted type-bar, a reciprocating slide directly connected to said type-bar by a pin-and-slot connection whereby a change of 6o leverage is effected during the movement of the type-bar to and from the printing-point, a finger-key and means for operativelyconnecting the finger-key to the reciprocating slide.

3. In a type-Writing machine, the combination of a type-bar, a reciprocating slide and connection between said slide and type-bar, which connection eects a change of leverage during the movement of the type-bar by the slide to and from the printing-point, a uni- 7o versal bar and means for connecting the universal bar to move with the slide in a movement thereof in one direction yand to permit the slide tovmove independently of the universal bar when said slide moves in an opposite direction.
