Application filed March '29, 1909. Serial-No. 486,421.

To all whom it may cmwern: -Be it known that I, FREDERICK .ALEXAN- mm, a citizen of the United States, residing at Brooklyn, Kings county,.city and State of NeWYork, have invented certain new and useful Improvements in 'llyperiting Machines, of whichthe following is a clear, full, and exact description.-

"lhisinvention relates to an improved arrangement of type-bars and key-levers for typewriting machines wherein the type-bar support and kcylever support are simultaneousiy'raised to allow the uppercase type The advantage of raising. the type; bars and keydevers'i'nstcad of the, carriage, as is done in the standard machines, is considerable asit'obviates the chances of the platen getting outof alinemcntwhen raised, due to lost motion in the carriage carrying and raisin parts. l

My invention comprises the'novel features of improvement and combination and a so' ciation of parts which I will now proceed to describe and finally claim, reference behad to the accompanymg drawings,-

8' forming part hereof, whereint pew'riting machine frame, having applied thereto my :improved type bar and key lever mounting; Fig. 2 is a vertical sectional front View, taken on a line a-a in Fig. 1; Fig.3 is a fragmentary sectional plan View, taken on a line b.b in Fig.2; Fig. 4 is a vertieal sectional rear view, taken on a line c' c in 'Fig. 1; and Fig; 5 is a'vcrtical secon a line (l q? in Referring to the drawings, a frame is indicated by 1, the said framcbelng provided with a platen 2, supported by a frame The, side members 1i and 1. of the frame 1 slid-ably support a type-bar supporting segment. 4, which is designed to pivotally support type-bars, onebar- 5; only being shown. The t-y c-bars arc pivotaliy and rcmovably supper ed by a rod 6, which is fixed in the segment in the usual manner.- The type-bars are proyidod with openings 7 having Ill com- :uuninlion therewith a. slot 8. The rod (3 normally rests in tlw'iop of opening 7, as shown in Fig. 1. ie typed-Jars are placed iemie'ativ (it each other by passing the rm (I througi the. passage 8 into the opening 7, which .will be readily Figure 1 is ,a cross-sectional view of a understood. The bars may be; withdrawn from the. se ment by an operation opposite to the one a uvedescribed.

The rear end of each bar 5 is provided with a curved slot 9, in the end of which a. pin 10, carried by an arm 11, is adapted to rest. The arm 11 is made integral with the key-levers 12, one only being shown. The rear end of the levers 12 are provided with a recess -13 adapted toengagc (in this in st:1nce)a horizontally movable rod 14, the. said rod being provided with guide-pins 14: which are movably mounted in a vertically movable barv 15. The rod 14 is he t in an extended position by springs -17 eel ig. 3), nuts 17 being carried by the pins 1 to limit the extended position'of the rod 14.

"To keep the key-bars apart, washers 12 may be used.

To slidably support the bar 15, I have em ployed recessed plates 16 (Figs. 2 and3). The recesses 16 in the plates are adapted to receive the remote ends of the bar 15. Ad-

jacent the ifrontof the frame 1, I place a. d

guide or comb pla to 18 having slots 19 adapted for the passage therethrough of the keylevcrs 12 (see Fig. 4). i

Another feature of my invention is a mechanism which is adapted to return each key-lcverto its-normalposition after the depression thereof, the said mechanism comprising-abar 20 which passes .under all of the key-levers 12 (see Fig. 4:), the said rod having, in contact therewith at each end thereof, a spring opposed pin 21 haviri an extension 21 wh ch passes under'the said bar 20, as shown. A spring 22 uctsto pull the Einj21 and bar 20 upwardly after a key has con depressed, the spring 22 acting againsta head 23 on the pin.21. To s'upport' the pin 21,- I provide brackets 24 (see Fig.4),

which are attached to the aide plate 18,-the

said brackets being pi'ovi ed at their lower ends with slots 25, into which the ends of the v rod 20 enter. The slot 25 acts to cause the rod 20'to move in a vertical direction. To

transmit movement from one end of the rod 20 to the other, I provide a rotatable 511mm, which carries arms 26, rovided'in the Outer end with. a slot 20!, which is adapted to re.-.

ccivc the rod 20. Should an end-key be de- )rcssvd, the rod 20 will move downwardly equally at cach'cnd-thereof, due 'to the mo (ion transmitting device, which consists of the said shaft. 27 and arms By the fore oing description it willbe take out downwardly, clear of the bar 14, readily unders d that I employ but-two and allow the'said bar to go back into the springs to restore all the type-bars to their remaining ke -levers. After having done normal position after the depressiontherethis I manip ate the level-"to cause the pin of. The key-levers 12 are each provided '10 thereon to pass out through the curved 7 with a lower-case or small letter 28 and an slot 9 in the correspondin typebar. If I upper-case or capital letter 29. a, desire it,:I fca'n takeout e corresponding 0 provide a means which will adapt the type-barin a manner -hereinbefore described. segment 4 for vertical movement, I provide Bymeafi's of my improved key-levePxand ioeach end'of the said segment with'extent pe-barmounting, I, can take out any o f 75 sions 30 (see Fig. 2) which are adapted to t em without removing the rest.
