Specification of Letters Patent. I 'Patentd N017; 1, 1910, Application filed Septemher'25, 1909. Serial No.

citizen of the Empire ofGermany, residing Typeriters, of which the following is a;

atpBerlin, in the Empire ofv Germany, have invented new and useful Improvements in specification.

Tlnsmvention relates to' mprovements in typewriters and has for its object an improved arrangement-of the typeha'rs and the construction thereof with a view of espe- 'jcially adapting the same for visible.type-.

; writers.

jand effective type which is especialy adapted.

fore the character of bar herein shown.

A further object of the invention is to PIOVlCl bar actuating mechanism of a simple "A further object of the invention is to fpr'ovide for a relatively short'or reduced movement for certain of the type bars and to dispose letters of most frequent 11188 on the type liars having the shortest movement I I and letters of less frequent use on type bars.

* having the greatest movement.

" The invention includes other features of novelty which will he more fully-described in "connection with the accompanying drawand which will be moreiparticularly "POIIItQCl out in and by the appended claims.

"In the drawings:--Figure 1 is a perspective view of a typewr ter embodying the main features of my invention and illustrating two type bars and corresponding parts thereof. F ig. 2 is a front elevationof the machine. Fig. 3 is a side elevation thereof.

Fig. 4 illustrates an end and side view of i an anchor 'eleinent. Fig. 5 illustrates a plan and end View of a portion'of one of the type bars and the actuatin link thereof. Fig. 6 illustrates a side and tront view of an upper portion of the type bar with the type block carrying the letters thereon. Fig. 7 illus trates a side and end view of an actuating element.

Like numerals of reference designate similar parts throughout the different figures of the drawing.

The key levers 1 are shown mounted upon a pivot rod 3 secured in suitable hearings to the frame 2-. Springs t normally return said levers to their position of rest. Anchor plates 6 are provided on each side of the machine frame and the upper portions said plates are provided with notched stepped portions 5 the higl'iest portions of Tonrrnu, a.

anchoring elements are leiwth from the innermost to the frame. Anchor elements 7 are mountwhich are near the center and the lowest portions of which are near the sides of.

ed on said plates and preferably said elements are provided with notches engaging the notched portions by they'are removably held irrplace: Said. providedwith lugs 8 constituting stops for actuating elements 10. Said actuating elements l 0-are secured to the anchoring elements 7 hy'pivots 9 and project vertically upwardly therefrom" and are arranged to swing vertically during operation. As "will be seen by reference to Fig. 1 the lugs 8 limit movement of the actuating elements 10 rearwardly. Said actuating elements 10 are normally held in the position shown by springs 11 connected therewith and to the anchoring elements 7. The upper ends of the elements 10 terminate in reduced extensions or pins 13. Said pins 13 extend through openings or apertures in links 14 as shown in Fig. 1.

, Type bars 15 are shown arranged in banks on opposite sides of the longitudinal center of the machine and each bar carries a type block 18 upon which. the letters are disposed. Said bars 15 each comprise vertical portions or arms I and horizontal portions or arms and the horizontal portions are mounted to swing on vertical pivots '17. As will be seen by reference to Figs. 1 and 5 the links Mare connected with the bars 15 atone side of, the

of the plates wherepivots thereof so that when the links 14 are moved forwardly the bars 15 will be swung inwardly to the printing position as shown in. Fig. 1.

The bars 15 are so arranged that the blocks 18 are alldisposed inhorizon'tal alinenient. .and the bars, in their position of rest project forwardly at right angles to the longit-udinal axis of the plates. The bars 15 are arranged to swing from their osition of rest to a printing position throng an arc of approximately and the innermost bars are preferably shorter than the outermost. bars, said bars increasing gi'adually in t e outermost bar. The pivots 17 OngWlllCh the bars 15 swing are disposed transversely of the longitudinal axis of the machine and in aime ment with each other.

The vertical and horizontal arms of the type bars also gradually increase in length from'the innermost to the outermost bars.

lie

It will thus be-seen that the innermost bars swing through arcs of shorter radii than the outermost bars and I preferably take advantage ofthis-arrangement by disposing the characters most frequently used upon the blocks of the innermost bars and the characters less frequently used upon the blocks of the outermost hars thereby insuring ease a lever 19 which may be pivotally supported The inner or shorter end of said lever 19 is connected at 22 to g the shift frame'lG. The pins 13 on the ac- Y at 20 on the frame '24.

tuatingelements 1.0 are of sufiicient length to retain engagement with thelinks 14 when c notched the bars 15 are raised by the shifting device.

1. In a typewriter, the combination with a frame, type bars provided with type blocks and having horizontal portions, vertical pivots for said horizontal portions of said bars, horizontally disposed links pivotally connected with said horizontal portions at one side of the pivots thereof, vertically swinging elements for actuating said links, key levers, and connections between said key levers and said elements.

'2. Ina typewriter, the combination with a frame, type bars provided with horizontal portions and having type blocksfvertical pivots for said horizontal portions, links pivoted to said bars at one side of the pivots thereof, vertically swinging elements for actuating said links,- notched anchoring plates. anchorin elements removably mounted on said plates, and pivotally supporting said swinging elements, key levers, and connections between said hey levers and said vertically swin ing elements.

3. In a typewriter, the combination with a framcptype barsarranged in banks on optween said key levers and posite sides of a central printing position, vertical pivots for said type bars, links pivotcd to said bars at one side of the pivots thereof, actuating members slidably connected with said ks, key levers, and connections between. said key levers and said actuating members 4. In a typewriter, the combination with a; frame, type bars having horizontal portions, vertical pivots for said type bars, links pivotally connected with said bars at one side of the pivots thereof, actuating elements slidably connected with said links and pivoted to swing vertically, a shifting device connected with said bar pivots for shifting the type carried by said bars, key levers, and connections between said key levers and said vertically swinging members.

5. In a typewriter, the combination with a frame, type bars having horizontal portions, vertical pivots for said horizontal portions, a 'slidably mounted shifting frame supporting said vertical pivots, means for shifting said frame, horizontally disposed links connected with said bars at one side of the pivots thereof, vertically swinging actuating elements slidably connected with said' links, key levers, and connections be- .tween said key levers and said vertically swinging elements.

v 6. Ina typewriter, the combination with a frame, type bars provided with horizontal portions, vertically disposed pivots for said horizontal portions, horizontally disposed clinks pivoted to said bars at one side of the pivot thereof, vertically disposed actuating elements connected with said links, anchoring elements supporting said actuating elements and provided with notcheslan anchor plate provided with notches for supporting said anchoring elements, the notches in said anchoring elements engaging the notches in said plates, key levers, and connections besaid actuating elements.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
