To aZZ whom it may concern:

Be it known that I, ALFRED G. F. Kciiowsin, a citizen of the United States, residing in Brooklyn borough, in the ooun cy oi isings, city and State of New certain new York, have invemcd V and useful improvements in Type-(Writing Machines, of which she iollowing is a specification.

, T his invention relates to typewriting ma.- cliines in which arelative shifting movement is effected between the types anci the platen, e0 enable either lower case or capital letters tobe Written, and perticularlyic those machines in which the platen rennilns stationary while the type-oars are shifted up and do wn.

- ment, whereby One of the main objects of the invention is to provide an improved connection between the type-bars and the key levers w ich extend rcm'wardly under the type-bar seg- Lil-6 type-bars are permit-ted to shift up and down while remaining con- 1 .nectecl to the levers.

I provide between inc type-burs which we mounted upon a sli-iiting segment, and the key-opemlcd oell cranks, which are mounted upon the framework of the me.

chine, a series of individual slides, which have pin-aml-slot connections to the typebars, for the usual purgiose' 1: 11d which also have pin-a11 l-slot connections to the bell cranks to permit relative play of these members during the prin'eing strokes, and also to permit up-and-down shifting of the tynebar segment for printing capital and lower case letters.

In another case, Serial l lo. 376,008, filed June 27, 1913),- n division of the present 0 e, 1 have claimed the means whereby the typebzir segment may be shifted.

Another object is to improve the means for shifting and guiding the type-bur segment.

Other features and advantages will. hereinafter appear.

Fig. '3 is a fragment of one of the slotted portions cf the type roclaslmft 16 which er-:i nis chine lJGRK-tililll There are iuo oi the our "1 l 1g. tseici rocn shaft in (31'1 es arms 18 114:- opcosice side sand allliS sh en eni-"ling from le Fig. 3 than: the opposite end oi n.

also terminates in a dead or dwell portion gage upper and lower stops 27 28, secured upon each of the legs 20, to arrest the segment when shifted in either directibn. The

lugs 26 have vertical slots 26 engaged by.

screws 26*, which adjustably fasten the lugs to the legs, the adjustment being determined by the throw of the slotted arms 18.

The segment is guided by pairs of rolls 29, each pair-comprising an upper and a lower roll journaled to a vertical carriage 30 and occupying vertical grooves 31, 32, the grooves 31 formed in the outer sides of the legs 20, and the grooves 32 formed in the inner sides of'a pair of plates 33 secured upon the opposite sides of the framework. Each groovehas converging or V walls 34, Fig. 8, and the ends of the rolls are coned to fit these converging walls.

The plate 33 is, adjustable toward the leg 20 at Figs. 8 and 9, to adjust it to the rolls, and take up play. The plate has a vertical tongue 35'to fit in a groove 36' in a part 37 of the framework of the typewriter. By

- means of upper and lower screws 38 and intermediate screws 39, the plate 33 may be adjusted toward the left at Fig. 9 to tighten the rolls 29, the latter having clearance at their ends, as shown at Fig. 8, to insure that they will always fit. The screws 38 are threaded into the fixture 37 and bear against the tongue 35, and the screws 39,

Cit

which are threaded into the tongue may be tightened, drawing the tongue firmly against the tips of the screws 38. Each car: riage 30, to which the rolls are journaled by pintles 40, has a lug 411, at its upper end, to catch upon the top of the plate 33, to sup port the carriage in normal position.

Upon the shaft 16 is a coiled spring 42. which partly counterbalances the weight of the segment and type-bars; the latter returning by gravity to normal position. A re-- turning spring 43 is connected. to one of the arms 18.

The type operating keys are designated as 44, and are mounted upon levers 45 somewhat similar in form to the levers 12,

and fulcru med on the same bar 46, and having similar returning springs 47. Upon the levers 4-5 are wrists 48 to engage slots 49 in the horizontal arms 50 of a set of bell cranks, the latter also comprising upright arms 51 having wrists 59 to engage slots 53 extending up and down in arms 54 provided upon slides55, the latter having wrists 56 to engage slots 57 in the type bars 1, to swing them upto print, (Fig. 1).

The slot 53 extend up and down in the direction in which the type bar segment is shifted, and is longenough to accommodate i such shifting movement, so that the station- I ary bell cranks 51 remain connected to the type bars when they are elevated to print capital letters as at Fig. 3.

The bell cranks are indicated diagram matieally in front elevation at Fig. 4, and it will be seen that between their ends nearly all of the bell cranks, have inward bends 58,

Fig. 4, to bring the upper ends of the bell cranks into proximity to'their respective op-L crating slides thearms 54 in said slides,

or actuators being preferably all vertical (front view in Fig. to agree with the vertical shifting of the segment, andthe tops of the bell cranksalsostanding vertlcally at said Fig. 4. It will also be seen at. 1

said figure, that the slides 55 are placed ra-- dially, and that the arms 54 are bent at corresponding angles to the bodies of the sl des to bring the arms to vertical positions. The

in the radial type-bar slots 3, and lie side by side with the portions of the slots, as at F 1g. 4; said slots therefore serving to guide the slides At Fig. 2, is seen a conformation of the lower portion ofthe segment 4 and a manner of mounting therein the type-bar fulcrum rod 2, as well as the front and rear curved rods 60, 61, upon which the slides 55 are guided.;-all ofsaid rods being'insertedin curvedslots'in the segment, the inner ends of the slots being enlarged to fit the rods, and retain them in place. The typebar operating slides 55 are provided with slots 62, 63,;wvhereby they slide upon said guide rods 60,61; and these slots are preferably formed on a curve, as illustrated at Fig. 1, which is nearly concentric with the fulcrum (i l ofthe bell crank 51. This is l done to give the slide a curvilinear motion, so that the wrist 56 thereon will have the desired action uponthe connected type bar;

the direction of the movement of the wrist 06 being first along the slot 57, so that the I type-bar is started slowly into motion, and

then transversely of the slot, so that the type-bar is speeded as it approaches the platen.

Variations may be resorted to within the scope of the invention, and portions'of the improvements may be used without others. Having thus described my invention, 1 claim: i 1.
