TYPEWRITING MACHINE.

Application filed February 23, 1926. Serial No. 90,035.

My invention relates to typewriting machines and has a particular reference to car- Y riage mechanisms.

rlhe object of myinvention is to provide a simple carriage for a typewriting machine with new and improved auxiliary attachments, which could be easily removed from the machine to be replaced with another one of different length.

Another object of my inventionis to provide a carriage which could be easily turned over on itsphinges to provide an easy aocess to the inside mechanism of the machine.

With my carriage mechanism the typewriting machine can 'be easily adapted for writing from right to left as is customary with the oriental languages.

My invention is more fully described lin the accompanying specification and drawings, in which l Fig. 1 is a partial sectional elevation of the machine showing my carriage and its supporting mechanism, Fig. 2 is a similar view with the carriage in a raised position, Fig. 3 is a plan View, Fig. 4 is a view from the inside of the machine showing bell ringing mechanism, Fig.- 5 is a sectional elevation of same, Fig. 6 is a. front view of the carriage lifting mechanism, Fig. 7 is a modied view of the upper carriage support, Fig. 8 is a detailed View of the carriage lifting lever, and Fig. 9 is a view showing my inking mechanism inv operation.

My typewriting machine consists of car-` riage end brackets 1 connected together with rods 2 and 3 which are used also to support the paper. A paper drum 4 is covered with rubber 5 and is journaled with its shaft' extensions 6 in the brackets land is provided with knobs 7 on the ends.

rlhe brackets 1 are attached to a guiding rod 8 by means of plates 9 supported by lugs 10 on the brackets. These brackets are also connected with lower guiding rods 11.

The rod 8 is slidably supported in brackets 12 with slots 13 for the plates 9. These brackets are attached to the main frame 14.

The right bracket 1 is provided with a lug 15 for the tape 16 connected with a1 spiral spring 70 inside of a housing 17.

A rod 18 is journaled in the brackets 1 and is provided with bell cranks 19 at the ends with handles 20. The lower ends of the bell cranks support an angle 21 with r a rack 22.. This rack is engaged by a pinion 23 on a shaft 24 which is connected with a ratchet mechanism (not shown). This ratchet mechanism may befof any suitable construction adapted to permit thecarriage to move a certain distance for each letter typed. A spring 24 attached to the bracket 1 keeps the rack pressed against the pinionl 23.

The lower guiding rod 11 rests von rollers V25 rotating on pins 26 which are support ed in the forks or clevises onthe ends of levers 27 which are attached to a rod 28 journaled in the member 14. The levers 27Yare provided with recesses'40 (see also Fig. 8) for the rounded end of a shift bar 42 journaled on a` rod 55. A spring 43 tends to keepv the bar 42 in a raised position resting against a cross bar 44fattached tothe frame 14. The other end oit the spring 43 is attached'to a boss 88 on the rear wall of the machine frame.

rlhe rod 11 ot the carriage is held in place by an upper roller`29 on a pin 30 which is fastened at an angle to a cross bar 89 (Fig. 6) the ends of which are. attached to side members 31 pivoted by pivots 32 to arms 92 attached to the rod 28. The lower ends of the side members 31 support a lower bar 93 with ulcrum plates 94 for a cross pin 34 ot a rod The plates 94 are provided with elongated slots 33 for the pin 34. The rod 35 is slidably itted in a vboss 36 in theI `trame 14 and is provided with a thumb head' 37. A spring 38 pressing against a collar 39 tends to push the rod to the right (Fig. 1).

A rack 46 is supported on the lug 45 of the brackets 1. ings 47 Vare placed on this rack and are provided with toothed plates 49 on levers 50 with handles 51 and pivoted with pivots 52 on lugs Springs 48 tend to keep the toothed plate 49 in engagement with the. rack 46, thereby locking the bushing in a given position.

The bush-ings 47 are provided with stops or lugs 53 adapted to engage arms 54pivoted with a screw 55 on the rear wall of the frame 14. l

The lower endof the arm 54 has a pawl 56 on a pivot 57. A spring 58 tends to keep the pawl in an operating position with its tail end 59 against the lower end of the arm 54.

The pawl 56 is adapted to engage a tooth 60 on an arm 61 pivoted on a pivot 62 which Sliding rectangular bushis attached to the Wall of the frame 14. This arm is bent in the middle and passes through an oblongaperture 63 in the frame 1%. The other end of the arm 61 has a resilient Wire 64C with a hammer 65 `on the end. This hammer is placed at a' short'distance from the inner Wall of a be-ll66. y y

This bell is mounted on a shaft 67 passing through the Wall of the frame ,14` and retained in its position With a hook63 iitting ina slot 69. v l y Y he other end of the shaft 67 supports the springdrum 17 with aspring mand is journaled in a bracket? 1. attached to the Wall of the frame 14: (thisbracket is not vshown in Figs. 1 and 2). y

ratchet wheel 79. is attached to the shaft 6T and is held With a paWl member 7 3 `pivoted `on aopivot 74. YIts outer end is` provided with a slot, Fitting over the `rod 35 (this rodis'not shown .in Figs. l and The `lower guiding rod 11 rests on a lug T6 ot a `sliding bracket `77 with circular slots 78. iispring y79 attached to a lug 8O on a type bar segment 81 (the type bars are Vnot shown) tends to press the lug 76 against the yrod 11. iin, inking roller 82 Yslides in the slot T8 with its ends 83.` This roller is made of alight material, such as aluminum or Wood and is covered with an ink absorbing Amar terial such as ltelt or cloth 84.

Tnstead orp the inking roller 822m ordinary ink-tape may-be used With my carriage mechanism, the tape drums being supported on Ithe sliding bracket 77.I The movement of the bracket ,7.7 Vis limited by a block '85 which comes in ,contact with a bar 86 form'- ing a part of the vsegment 81 or the bracket 1.

'.Tn operation my carriage slides with its guiding rods 8 and 11 on the-rollers 25, retained by roller 29, and in the brackets 12. The latter, may be alsoc provided with rollers to ,reducethe friction. The construction ot the Acarriage and ot' the machine frame, as shown, is such, that the carriage'can be moved freely in either direction and can be even completely removed, the plate 9 sliding :through the .slot 13. Another carriage, larger or smaller, can be then insertedwithout disassembling any parts ot the machine, the only thing heingynecessary is to disconnect the end of the tape-16 from the lug 15, and to releasethe stops as explained later. During process `ot xwriting the carriage is Y.moved .manually to `theright thereby Winding the spring 70. The carriage, however, is prevented ltrom sliding back except hy `steps tor each letter typed, the pinion 23', engaging the rack 22, being held by the ratchet mechanism (not shovvn),fwhich may be of a standard construction or similar to one shown-.in my patent application Serial No. 65,7%, Atiled Feb-3, 1926.

in order to release the carriage from the ratchetmechanism thehandle 20 of the lever 19 isdepressed, thereby `disconnecting the rack 22 .from the pinion 23. The carriage may be thenV moved manually back and forth..

yFor l. typing capital letters the register' shift key/"ft2 is depressed against the tension o1'` .spring 13. The carriage turns around on the axis of the shaft 8, the parts taking new ,positions as indicated with dotted lines in Fig. 1. `The Slot 13 is suiiiciently large to pass the plate 9 in this raised position. f he Vslot 33 allows the arms 31 to beraised :Without changing `the horizontal positionfo'it th'egrod 35. n In orderto have access'toft-hc'inside mechanism of `the machine 'for cleaning, adjusting etc., the carriage may .beturnedon'the axis of .the shaft 8 toa raised position illustrated in Fig. 12. For this 4purpose the thumb head 37 is pulled out .thereby turning the arm 31 on Y,its pivot 32 to Aa position ,(F ig. Q) in which the' upper roller 29 does not interfere with the turning olthe carriage out otengagement With the ylower roller 25. The rack 22 slides away fromthe teleth of the pinion 23. This vpinion is made withllonger teeth kthanon the ,rackin order to maintain an operating engagement when the carriage is raised for typing vcapitalletters.

The ylug` 15 isdi-sconnected Vfrom the tape 16 Ytor raising the carriageto an inoperative position, (or it may be .le-tt connected).

The bracket 77 is held in its position fby the rod 11 which presses on the ,lug 76 againstthe tension 01": the spring 79. This spring forces the "bracket '7,7 up when the rod 11 is raised flor capital letters.

JWhen the carriage is turned to the open or inoperative position (Fig. 2)., the plate 8.5, Vattached to the lug l76, 4strikes theretaining bar 86 which keeps it .from sliding oft" the segment 8 1.

The iukng :roller S11 can slide in th'eslot 7-8.v Itis placed vin l'such position that the type bar strikes it before coming incontact with the drum 5, and the ink vfrom ythe roller covers vthe type oit the type bar, so that the next moment-,the type leaves ,inked impressiononthe paper on the drum. Under pressure r from l the ytype ybar `the roller Amoves up in the slot thereby admitting th-e lpassage underneath .of the `operating -end of thetype' bar. The slot is .placed in "such position that the roller in the upper positiongis held by the .upper 4flat tportion ofthe type bar. VThis device` can-operate `withany ordinary type bars, .which have Wide lupper portion.'- Such Vtypebar 87 is shovvnvwith dotted lines vin vl*`,ig..1, and also .in Fig. 9.

.The `bracket .71 y(Fig. .6) has an upper cross bar 96 :with a hearing aperture97 for thesha-t :124,.0the pinion23. This bracket :be then pulled out with the bell, andthe between rollers 98 and 99 is attached to the rear wall of the frame 14. The rocking frame, formed of arms 92 and members A3 1 and 93 is placed outside of the bracket 71. Their correct relative position is shown in Fig. 6.V

The upper guiding rod 8 may be placed to reduce the friction.

-The inside shaft `extension for the centralspring' 70'fits inthe hub 103 which is prevented from the' rotation on the shaft by means of a screw 101 theend of which slides in a keyway 100.A The hook 68 which fits in the groove 69 may be turned on its pivot 104 thereby releasing the shaft which may The carriage, when moved to the right,

winds the Vspring by turning `the case of housing 17. To release the spring the lever 7 3 is moved on its pivot,.r`eleasing one notch ata time. Y

' The above described arrangement affords a very simple construction for assembling or taking apart the spring mechanism, also for winding it. Another important advantage lies in its central position, so that by simply reversing the spring drum anda few other auxiliary parts with the addition of new stops 47, my typewriting machine-can be used for writing from right to left.

Important advantages of my carriage mechanism are that it represents a single unit sliding in its supports for spacing between the letters, can be raised or lowered for typing capital andV plain letters, can be turned outwards to afford an access to the inner mechanism of the machine. The whole carriage can also-be easily completely removed from the machine and replaced with another of a different length, without changing any parts of the machine or taking it apart.

My inking mechanism is also very simple in construction and is arranged to automatically adjust itself for dierent operating positions of the carriage, remaining also in position when the carriage is completely removed or fully raised.
