SPECIFICATION forming part of Letters Patent No.`737,-163, dateduAugust 25, 1903.

Original application led February 6. 1902, Serial No. 92,851. Divided and this application iiled May 29, 1902. Serial No.109,521.` (N ovrnodel.)

' To all whom it may con/cern.-

- Be it known that I, CHARLES H. SHEPARD, a citizen of the United States, and a resident of the borough of Brooklyn, city of New York,

in the county ofKings and State of New York,

v have invented certain new and useful Improvements in Type-Writing Machines, of which'the following is a specification.

^ This case is a division of my application ro filed February 6, 1902, Serial No. 92,851.

My present invention yrelates to caseshifting and line-lock `mechanisms for type- Writing machines. '5

vIt has been difficult heretoforewhen operating a type-Writing lmachine at high speed to so time the successive operations of the shift-key that the upper and lower case printing characters will appear in proper alinement. If, for instance, there isv a sluggishzo movement of the shifting mechanism or a premature operation of a type-key, the impression made before the completion of the shifting operation is either out of alinement or a blurred and imperfect impression is produced upon the paper, and in some instances the impressionwill include a part of the upper-case and a part of the lower-case character. In correctingV such mistakes? the appearance of the page is marred and much 3o time and labor consumed. Still other faulty operations are liable to occur .in some typewriting machines heretofore devised, such as the clashing or interlocking 0f the type-carriers or other parts.

One of the objects ofmy presentinvention is to overcome the dif'culties above referred to and to provide at the same time simple and efficient line-lock mechanism whereby the type-carrie'rsvmay be automatically locked reference characters indicate corresponding out of operation 'whenan end 0f a line is parts in lthe various views, Figure 1 is a ver- 5o 'tical sectional view, partly'in section, of one form of type-writing machine embodying my invention, the section being taken from front to rear of the machine. Fig.` 2 is a like View ofthe same, showing a different `disposition ofthe parts. Fig. 3 is a detail iisolated diagrammatic perspective view of the case-'shifting mechanism, together with Qthe means employedforpreventing an operiation of the type-carriers While the case-shift- 6o ing mechanism is being'operated, as well as fthe line-lock mechanism, which cooperatesA `therewith. Figa is-a detail plan view of a 'portion of the dog-rocker frame, lto be here- 'inafterv more fully described. Fig. 5 is a de- 65 ltail isolated side` View 0f a portion ofthe Eblocking and line-lock mechanism. Fig. 6 is a side view of one of the blocking fingers or catches and the arm which c'arriesit.

In the various views parts have been om-it- 7o tedV or broken away to moreclearly illustrate other features of the structure. A

I have shown my invention applied to a No. 6 Remington machine, though it should be understood that the invention or any one lor more of the separate features thereof may 'be applied to any other character of typewriting machine. l

The frame 1 is surmounted by a top plate 2, wlichsupports upright studs 4, to which 8o the traverse-rods 5 6, respectively, are connected. lTheusual carriage 7 moves from 'end to end of the machine on the traverserods and carries a platen-frame 8, in which fa platen 9 is ymounted to revolve. The front 85 end of the platen-frame is supported upon a -shift-rod 10, which is connected to the vupper ends of upright shift-arms 11 12, located near lthe opposite ends of the machine and secured to a rock-shaft 13, that isV adapted to 9c rock' in bearings formed'rinarms or supports- 14D, which depend from the top plate 2. The. shift-rodi() is moved transversely, Vas will hereinafter more clearly appear, to move the `platen-frame and platen in a direction trans'- 95 verse to its feed to change the case-position thereof. This transverse movement ofl the platen and its frame is limited by stoppins 15, carried in the usual manner by the carriage 7 at each end thereof and which cooperate with each end of a projecting pivot rod or shaft 16, which pivotally connects the platen-frame to the carriage 7 through the usual links 17.

Character key-levers 18 are fulcrumed at 19 in the frame 1 of the machine and a're provided with linger-keys 20 and restoringsprings 21. Each key-lever 18 is connected to a link 22, which is in turn connected to a type bar or carrier 23. A spacing key or bar 24 is connected at each end to a key-lever 25,.

both of which are likewise fulcrumed at 19 upon opposite sides of the keyboard and are provided with restoringsprings 21. The parts thus far described constitute a portion of the well-known No. 6 Remington machine, and a more elaborate description thereof is deemed unnecessary.

Extending transversely beneath the keylevers 18 and 25 is the usual universal bar 30, which has connected thereto at each end a link 31, the links being connected at their upper ends 32 to a transversely-extending bar 33, which is carried by an arm 34 that extends from a rock-shaft 35, mounted in bearings in the arms 36, that are secured at 37 to a plate-like bracket 38, which extends downwardly from the top plate 2. The rockshaft 35 is restored to the normal position by a spring 39, which is secured at one end 40 to the bracket 38 and is secured at its opposite end 41 to the rock-shaft. Extending rearwardly from the rock-shaft 35 is a crank-arm 42, which is pivoted at 43 to a link 44, that in turn is pivoted at 45 to a two-arm lever 46, that is pivoted at 47 to a depending bifurcatcd bracket-arm that extends downwardly from a bracket-plate 48, that is secured by screws 49 to studs 50, which project from the plate-like bracket 38. The rear end of the two-arm lever 46 is pivoted at 51 to a link 52, which actuates suitable feed-dogs 53, that coperate with an escapement-wheel 54, operatively connected to a shaft that revolves in av bearing 55, secured to the top plate and carrying at its forward end a feed-pinion 56, that meshes with a feed-rack 57, carried fby the carriage in the usual manner.

Referring particularly to Fig. 3, it will be observed that the shifting arm 11 at the righthand side of the machine extends downwardly beyond its pivotal center and forms two arms 93 and 94. The arm 94 is pivoted at 95 to a link 96, which has its opposite end pivoted at 97 to a shift-key 98, which is provided with the usual finger-key 99 and is pivoted at 100 (see Fig. 2) to an upwardly-extending inverted- U-shaped bracket 101, that is secured to an arm 102, which projects laterally from the frame 1 of the machine. The shifting arm 12 at the opposite side of the machine is provided with a depending portion 103, which has a link 104 pivoted thereto at 105. A screw 106 projects through a slot 107 in this link and is threaded into an opening in the part 103. The pin 106 thus constitutes a stop which limits the movement in opposite directions of the link with relation to the part 103. The upper end of the link 104 is pivoted at 108 to a connecting rod or link 109, that is pivoted at 110 to a U-shaped yoke 111, that surrounds a shift-key lever 112, which is pivoted at 113 to a fixed arm 102a of the machine in the same manner as the shift-key 98 and is provided with a finger-key 114. The depending part 103 likewise has pivoted thereto at 115 a shifting piece 116, that is apertured at 117 for the reception of a pin or screw 118, that is secured to the piece 103 and projects through said slot or aperture 117 and limits the movement of the shifting piece with relation to the part 103. One arm 119 of this shifting piece is provided with a laterallyprojecting finger or pin 120, which extends into an opening 121 in the link 104. Another arm 122 of the shifting piece has connected thereto at 123 a spring 124, the lower end 125 of which is secured to a screw-eye 126, that is fastened to a fixed portion of the machine.

From the foregoing description it will be understood that when the parts are in the position represented in Fig. 3 of the drawings the spring 124 will exert a pressure to maintain the shift-rod 10 in the foremost position, where the platen is maintained in a position to coperate with the lower-case type on the type-bars. When,however,the fingerpiece 127 is moved up, such movement is effective to turn the shifting piece 116 on its pivot 115, thereby moving the upper end 123 of the spring to the opposite side of the pivot 115, at the same time moving the upper end of the link 104 forward to the opposite side of the pivot 105 thereof. The spring 124 is at this time eective to maintain the shiftrod 110 in the rearward position, at which time the platen is in a position to receive the impact of the upper-case type on the typebars. When the parts are in the position represented in Fig. 3, the finger-keys 99 and 114 are adapted to momentarily shift the shift-rod 10 and the platen which is operatively connected thereto to change the printing position thereof from lower to upper case. When, however, the finger-piece 127 has been moved upwardly, as previously described, a depression of the shift-key is effective to temporarily shift the platen from the upper-case printing position4 to the lower-case printing position. The case-shifting mechanism thus far described constitutes a part of the wellknown No. 6 Remington type-writing machine and need not be further described.

The depending arm 93, hereinbefore referred to, has a rearwardly-extending rod 128, pivoted thereto at 129. This rod is provided with a laterally-extending pin 130, that projects into an inclined slot 131 in an upwardlyextending arm 132,which is secured to a rockshaft 133. This arm has pivoted thereto at 134 a blocking piece or finger 135, which is normally maintained in a fixed relation to IOO IIO

the arm 132by a spring 136, which is Yconnected at one end 4to the finger 135 and is se.-

cured at its opposite end'i'e/ totte arm 132.' The ,rock-shaft -133 is provided near its oppo site endfwith a secondv upwardly-projecting arm 138,that corresponds tothe arm 132, and,

like said arm, it has pivoted thereto at 139 a. blocking piece or finger 1 40,wh ich is normally,

maintained in a fixed position with relation to the arm by a spring similar to the spring 136, hereinbefore described. The rear endof therod 128 is pivoted at 141 to an upwardlyextending link 142, which is pivotedl at its upper end 143 to one arm of a bell-crank. le ver 144. The other arm of this bell-crank lever lis preferably rounded at its end 145 and is seated Within ya slot of a yoke 146,*which yarms 132 and 138, togetherfwith their blockharv33 andwill' be `maintained yin 'the spacesl formed between the projecting arms 153 and tends to maintain the rack toward the right,`-

but permits under conditionswhich will here inafter appear a slight longitudinal movementof the rack. The rack 147 carries an adjustable stop `or line-lock abutment 151, with which a cooperating ,trip or abutment 1,52, carried by the carriage,v is adapted toy contact in the travel of the `carriage from right to left oriny the direction of its feed. l

In the operation ofthe case-'shifting mechanism and the automatic lock therefor the blocking-lingers 135`and 140 are normally maintained either j ust forward or back of the transversehar 33, or what maybe termed the dog-rocker frame. Vihen the parts are in the position to write lower-casecha'racters,

as shown in Fig. '3, a depression of either of the temporary shift-keys 99 or" 114 or an up ward movement of the permanent` shift-key 127 willcau'se the shift-rod 10 to bevmoved toward the rear of the machine. This movement of theshift-rod and the parts connected theretowill cause the rod'128 to ybe' moved forward, togetherfwith the arrn 132,v con! nected to said rod,',thus .producing a rocking 4movement of the shaft 133,v which effects a like movement of the arm 138 at the' other The forward move# ments ofthe arms 132'and 138 bring the block-.

side of the machine.

ing-fingers into the path'of the transverse bar 33, audit cannot be depressed until the ing-fingers, have completed their forward movement. At' the completion of the forward movement of these parts the blockinglingers will have j ust cleared the transverse the transverse bar to which they are secured.

It will'be, understood that if the operator at-f` tempts to depress a characterlkey or' the space-bar during this shifting operation, 'the blocking-'fingers will arrest a movement of the transverse bar 33, thus preventing an actuationV of the type bars or escapement mechanism. As soon, however, as the shifting movement has taken place the blockingfingers areclear of the transverse bar 33 andA the fingers 153 connected ther eto, and the. operator may at this time depress the charac-` ter-keys or the spacingkey.` When theper- ,manentshifting device is moved by raising the finger-piece 127, so that all uppercase characters will be Written, the arms 132 and 138 and the blocking-.fingers carried thereby will bemoved forward totheposition repre-I sented in full lines of Fig. 2 of the drawings. A depression of the temporary shift-key114 or a movement of the finger-piece 127 to the position shown in Fig. 3 will at this time cause the blocking-fingers to be moved with theirv arms toward the rearof the machine and across the path ofmovement of the`trans; verse bar 33 in order to prevent a depression thereof until the'completion of the caseshifting movement.

Should the operator attempt to actuate the' finger-piece 127 von-either of the shiftkeys 99 or 114 when a character-key orthe spacekey is partly or fully depressed, it will merely 'result' in the blocking-fingers beinghrought into engagement with either side of the trans- Vverse har 33 or the arms 153 thereof, and the pivotedl lingers will yield against the tension of their springs, so that no injury can be done either to the rocker-frame or tliengers. As. soon as the finger of the operatoris removed -from the keys the blocking-fingers will resume their normal [positions withrelation to the,

arms which carry them, the springs of said blocking-arms restoring themjto the normal position.

and-slot connection 130 131 and through the rod-shaft 133 to the corresponding arm 138. If the parts are in the lower-case printing position, (represented in Fig. 1,) the blocking-fingers 135 and'140, carried by these arms, will be projected beneath the transverse bar 33 and thus prevent the depression thereof. If, however, the parts are in the upper-case printing position, then the arms 132 and 138` will normally assume the position shown in full lines in Fig. 2 and the actuation of the line-lock mechanism will move the arms forward, together with their blocking-fingers, to the position shown in dotted lines in Fig. 2, where they will cooperate with the ingers 153, carried by the transverse bar 33, to prevent a depression of the bar and an actuation of any of the character-keys or the spacing-key.

From the foregoing description it will be seen that the instrumentalities which enter into the mechanism for automatically preventing an actuation of any of the character-keys or the space-key during the shifting operation from the lower-case printing position to the upper-case printing position, or vice versa, likewise enter into and constitute a part of the line-lock mechanism, so that the one set of mechanism acts in a twofold caacity. p

Should the operator desire to write one or more characters after the line-lock mechanism has been operated in order to insert one or more additional characters, it is merely necessary to push in the button 154, that extends forwardly Irom the top plate 2 of the machine and which is connected to a rearwardly-extending rod 155, that is guided in suitable bearings beneath the top plate and is provided at its rear end with an upwardlyextending finger 155", that is seated in a longitudinally-extending recess or slot in an arm 156, that is secured to and projects downwardly from the rack 147. The eiect of this movement is to rock the rack 147, thus carrying the stop or line-lock abutment 151 out of the path of the coperating abutment on the carriage, and the spring 14:9 will restore the rack to the normal position, thereby releasing the line-lock to permit one or more additional characters to be written. When the finger-piece or button 154: is released, it, together with the parts connected thereto, are restored to the normal position by a coiled spring 157, which bears at one end against the rear face of the button and at its opposite end against one of the bearings 153.
