JACOB FELBEL, OF NEW YORK, N. Y., ASSIGNOR TO REMINGTON TYPEWRITER COM- PANY. OF ILION' l NEW YORK, A CORPORATIO .7 OF NEW YORK.

TYPE-WRITING MACHINL.

To all hom it may concern:

lie it known that I, .lacon FELBEL, citizen of the linited States. and resident of the borough of Manhattan, city of New York, in the county of New York and State of New York. have invented certain new and useful Improvements in Type-\Vriting Machines. of which the following is a specification.

My present invention relates primarily to the universal bar mechanism of typewriting machines and its main object is to provide new and improved mechanism 0 the character specified.

More particularly my invention has to do with a type bar operated universal bar which is s'hiftable automatically during the case shifting operation but is mounted independently of the element which is shiftable to effect the change of case. this element in the present instance being the type bar segment or support. This independent mounting of the universal bar enables it to be disconnected at will so that it will not participate in the case shifting movement or so that it may itself be separately shifted; constructions which may be taken advantage of for various purposes, for instance. enabling a simple and effective dead key 01' accent key construction to be provided. In carrying out my invention novel case shifting meeha-. nism is provided.

To the above and other ends my present invention consists in the features of construction. combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

In the accompanying drawings which illustrate several adaptations of my invention. Figure 1 is a front to rear vertical sectional view taken bout centrally of a typewriting machine SlOWlIlg one. form of my invention applied thereto, some of th. parts of the machine being omitted. Fig. 2 is a vertical transverse sectional view taken the dotted iinc f it in Fig. 1 and looking rearward.

Referring first to the construction illustrated in Figs. 1 to 3, inclusive, the machine shown, though differing in details, generally resembles the Monarch typewriter, and has a main frame comprising a posts land a top plate 3 above which are. fixed track-ways 1 anti-friction balls 5 with the rear or slide bar Got a carriage which further comprises forwardly extending end bars 7 that provide bearings for a rotary platen 8.

- C 'perative with the front face of the platen S are a segmentally arranged series of type bars 19. each type bar having fixed t its freeend a block provided with two t pes. the outer type '20 being the lower case tvpe and the inner type being the upper case type. The type bars may be pivoted on a common pivot wire which is mount ed on a shiftable type bar segment or element 23. in any well-known or desirable ianner. The type bars lit in and are partly guided by converging slots in the segment. Each type bar is connected by a rink ill with an upright sub-lever which is pivoted on a key lever 26, said sub-lever being slotted at- 27 near its lower end to cooperate with a fixed abutment The set of hev levers 26 fulcrum on a plate 29 nation-ted in the rear portion of the base and each key lever is provided with a key or but on 36 and with a restoring spring 30. Near their outer end portions the type bars wanted on a frame 32 secured to 's 33 that are rigid with and prord from the segment or type bar sot Said segment and said rest are shiftable at. will to change case by key opl case. shifting dcri es of suitable cousti on. At its opposite ends or sides the sea nt is provided with. grooved track ing stop devices 38 and 39 are adjustably secured in pairs to the rear faces of the posts so The halt bearing mounting of the segthe stop devices therefor may be cl Monarch construct-ion.

' or t-heseginent 23 and shift it up devices are provided which are or cars it) extending The dog.- 13 and H- into the sides of the base 1.

ally supported by a curved rest 31 downw "d from the segment. one near each end. thereof. bald devices comprise a pair of upright links or bars .41, the upper ends of which are pivotally connected at 42 to fixed to said rock shaft near its ends by'set screws 47. The rock shaft mounted on pointed pivot screws -18 that are threaded Between the hub 45 of each crank arm and the adjacent end of the rock shaft there is fitted over said rock shaft a hub 49 of a forwardly extending crank arm 50. said hub being pinned or otherwise fixed to said rock shaft, so that both crank arms 50 are rigid therewith. Fitting loosely over the rock shaft 46 inside each crank arm 50 and extending forward contiguous to said crank arnr is a thin arm 51 which is secured to the crank arm by a screw 52. Said arm 51 is longer than the crank arm and provides a bearing at its outer end for a roller 53 that under-' lies a shift key lever 5-L there being two of these shift key levers one at each side of the machine. Each shift key lever is pivoted on a pin or pivot screw 55 near its rear end,

said pin being supported on a stationarybracket 56. Each shift lever 54 is provided with a shift liey. 57 and behind its pivot or fulcrum 55 is located a restoring spring 58 which tends to return it after actuation. A depression of either shift key operates on the underlying roll 53 to swing down the arms 51 and 50, rocking the shaft 46 and swinging the crank arms 44 upward, this upward movement of the crank arms ll be} ing transi'nittcd through the links .41 to the type bar support comprising the segment 23 which is thereby shifted or raised to an extent limited by the engagement of the stops 3? with their associate stops 39. The result of this shifting movement is to render the upper case types :21 operative when the type bars are actuated, the types 20 having been carried upward so that they will not strike against the platen. \Vhen the shift key is released the type bar segment and connected parts are restored by gravity to normal position where the stops 36 engage with their associate stops 38. Counterbal' ancing springs 59 are provided which tend constantly to lift the type bar support and in a measure overcome the weight of said support, although nothaving tension enough to lift the support from its normal position in which the stops 36 engage with the stops 38. The effect of these springs, however, is to render the touch on the shift shifted parts in shifted'position ou the.op-' eration of a locking .62, the

kevs much lighter. The springs 39 are eon-' 'nected at their forward ends to pins (3O fixed provided shift locking devices-of suitable that found? in the Monconstruction such as arch mach ne and which will shift and maintain the type bar segment .and other ey-lever indicated at arts being locked by the-actuation of t 1e associate shift key 57 at the lefthand side ofthe machine. i

As a result. of this reciprocation of the escapement devices the carriage will advance a letter space distance toward the left.

The means for automatically shifting the universal bar when the case shifting mechanism comprising the key controlled shiftable element or segment 23 is operated, comprise connections between the support or frame 63 and the rock shaft 46. Said connections include a pair of upright arms or links 87 arranged just outside the shift links 41. Each arm 87 is provided at its upper end portion with an inturned lip or ear 88 which receives a headed screw 89 that is threaded into the lateral extensions 64. the

arm however being preferably loosely supported by said screw. At its lower end the arm 87 is perforated to fit over the associate screw or stud 43 outside the link 41. The construction is such that "when the actuation of either of the keys 5? or of the key 62, causes-the rocking of the shaft 46 andthe upward swinging of the crank arms .4 and the shifting of the type bar segment, the arms 87 will be concurrently movednpward. shifting the frame 63 which carries with it the universal bar. so that the universalbar in the mounting of the universalbar supporting frame. As shown in Fig. 4 each of the guide pins (36 may cooperate with a bracket 90 which differs from the bracket 80 in having two perforated guiding cars 91 one near the top and one near the bottom of the bracket. This is also true of the bearing illustrated in Fig. :1 in which each bearing pin (16 is adapted to fit into an elongated perforation indicated at 92. this perforation being in a stationary part 93.

In the modification illustrated in Figs. (3 and T. Fig. 6 is a plan and Fig. 7 an elevation of a sliding construction which may replace the guide pins of theformer constructions. A guide or track-way 94 which m y be T-shaped in cross section is fixed to the front of the post 34 and the end portion (itof the llni\'cr al ar support is provided with a T-shaped slot or opening by 'which the support is fitted over the trackway 94 and is adapted to slide up and down thereon.

No ribbon mechanism is illustrated'in the drawing but the construction illustrated in Figs. 1 and Q as well as the constructions presently to be "described may be equipped with the usual ribbon feeding mechanism of the Monarch machine or any other suitable ribbon mechanism; together with ribbon vib 'ating mechanism which may be connected to be operated from the type bar actuated universal bar. although if preferred the vibrator may be actuated in the usual way by a universal. bar actuated from the key levers. The segmental supporting plate til-l. as best appears from. Fig. 3. and the correspondingpart, plate or frame in the other constructions are pro ided each with a central vertical slot to accommodate some of the vibrator actuating devices. A Each of the constructions may alsobe provided with a center guide for the type bars, this center guide being mounted on the support for the universal bar and participating in the shifting movements of said support.

A construction embodying an ,extension or further modification of my invention is illustrated in Figs. S43. inclusive. In said construction provision is made for shifting the universal bar automatically from lower to upper case position when a case-shifting key is actuated, and furthermore a special printnig key is provided whicl ris etl'ectivc automatically to restore the universal bar from upper to lowercase position concurrently with the operation ,of the connected type bar which is so constructedthat it is ineffective to actuate the universal bar it this time. The consequence is that though the type bar will print the carriage will not space. makinga construction which is simple andetfective for use with an accent type. or. as it is sometimes called. a dead a key mechanism.

Said levers have stationary pivots120 and are provided at their rear end wortions withsnitable restoring springs. 121

The universal bar frame 123 similar to tlia Figs. 1-3 construction is provided-with a curved'universal bar proper 121 and is slidably mounted on a rod 125 and pins 120 which project rearward from a shif'i'able supporting frame or plate 127. Said uaiversal bar frame is connected as in the Fig-1's. 1-3 construction with a dog carrier 15' by a link 83. the carrier supporting dogs 13' and 11' which cooperate with an escapement The frame 12? is slidably mounted on the posts 109 independently of the segment 102 as in said Figs. 1-3 construction. but'the meansfor shifting the universal bar and its support 127 up and down are different from the means in said construction. In thepresent instance the shifting means comprise two upright arms 128having lateral ears l29 which are connected by screws 130 to the front of the vplate 127 said arms at their lower ends be- The tension of'the springs 102 is snitablyguided' 'tive to lift the arms porting ing broadened somewhat and formed with vertical slots indicated at 131 to fit loosely over one' of the lateral studs 111 outside the associate link 1 13.

thelower ends of the studs .111. 132 is not suflicient, however, to overcome the weight of 8 the springs 132 maintain the slots 131 engaged with the segment 102 and its type bars so that-- the studs 111 act normally as stops to l mit the upward movement of the universal bar and its supporting frame 127. The lower ends of the arms 128 are connected by' 'a cross.

rod 131 which lends stiffness to the arms tending to prevent a lateral vibration or displacement. The cross rod also has the functions ofa stop being adapted as presently to be described to contact with the lower end or face 135 of adevice or extension 130 which is suitably fixed to or ,formed in- .tegrally with the special or accent key lever 106. ,In lower casev position the face-135 is above and separated from'the rod 131.

Referring to the operation of the construction just described the parts when set for studs 111 on crank arms 115 which are rigid writing lower case characters are in the positions illustrated in Fig. 8. atwvhich time if the accent key lever 106 is operated, itslower case type 97 will cooperate with face 99 will the platen 95 and its actuating ca'uslng the strike the universal bar 121,

frame 123 to slide rearward. said frame beface 135 into contact withithe rod 131. The

relationship betweenthe type bar support -102 and the universal bar 121 in'normal lower case position is illustrated in Fig. 11. W hen it is desired to print with the accent type 98 the first operation is to depress the shift key 122. causing a change in'the relationship of the parts which is illustrated in Fig. 9. The effect of actuating theshi ft key is to rock the' shaft 116. swinging upward the crank arms 115 and studs 111 and there by through the links 113 shifting the seg= ment 102 and the type bar supported thereon to upper case position. As the studs 111 move upward the springs 132 become eflec-- 128 and shift the supframe 127 together with the uni- 121. The shifting movement of the universal bar will continue until its supporting frame is arrested by the engagement of the cross rod 131' with the face 135 at which time the universal bar will be in" upper case position, its relationshipwith the versal bar type bar support 102 and the type bars being the same as in lower case but said support and said universal bar both being at this time raised above the normal lower case position. This will be better understood by a comparison of Fig. 12. which illustrates the two parts as they are at this time. with Fig. 11. If with the parts related as in Fig. 9 the key lever 10G controlling the accent type 98 be actuated. the face 135 acting against the rod 131 will overcome the springs 132 and move the arms 128 downward. returning the fralne 121' to its lower position and restoring the universal bar automatitailly to lower case position while concurrently the connected type bar 96 will be operated. causing the accent type 98 to cooperate with the platen. The restoration of the universal bar, however. to lower case position has brought it opposite the notch 100 so that the type bar will not be etl'ective to actuate the universal bar but will print without causing any escapement movement of the carriage. The relationship of the parts in printing position is illustrated in Fig. 10, while the relationship of the universal bar in respect to the type bar support 102 is diaglanmiatically shown in Fig. 13 where it may be readily compared with the relationships of the same parts when they are in the earlier positions.

Referring to the form of my invention above described in connection with Figs. 8 to 13, inclusive. it will be observed that there is provided a case shifting element. in the present instance. a type bar supporting segment and a shiftable universal bar, in combination with means controlled by asingle key for simultaneously shifting said element and said universal bar. and other means for shifting said universal bar independently of said single key: that said single key. in the present instance, is a case shifting key; that the means for shifting the universal bar independently of the case shifting key comprises a printing key lever connected to the accent type bar: that said printing key lever shifts the universal bar to change its case position in an opposite direction from that in which it is shifted by said shift key; that means are provided tending constantly to shift the universal ba in the present instance from lower to upper case position, said means being spring means or more soecitically still two springs one connected to each of iw links or arms that are comprised in devices for shifting the universal bar to change its case position; that. said shifting devices further comprise a shiftable frame on which the universal bar is movable by the operation of the type bars; that stop means normally prevent the operation of said spring means. said stop means in the present instance being lugs or pins extending laterally from crank arms clusive.

on a rock shaft that is controlled by the case shifting keys: and that said stop means or stops move automatically when a shift key is actuated. this automatic movement permitting the spring means to become effect ive.

Still another modification embot'lying some of the principles of my present invention is illustrated in Figs. 14 to 16. in-

In this construction the type bar system. the mounting of the segment and universal bar and the devices for shifting these elements correspond substantially with the Figs. 1-3 construction and need be but briefly described. In the Figs. 14m; construction. however. provision is made for disconnecting the universal bar and its supporting frame so that the case-shifting keys will be'inett'ective on the universal bar which will remain in lower -ase position at all times both when the type bar segment is in lower case position and when it is shifted to upper case position. The throwing of the universal bar out of the control of the shift keys and the restoration of said universal bar to such control is preferably ef fected at will through the actuation of a special key.

Referring to Figs. 1-1. 15 and to, rising from the base frame 137 are stationary posts 138 on which the type bar segment 139 is mounted to move up and down. The type bars 19' that are mounted on the segment and their actuating devices may be of any suitable character. corresponding for ex ample with the construction shown in Fig. 1. The means for shifting the segment 139 up and down comprise b rs or links 1-H) pivotally connected at their upper ends to the segment and at their lower ends engaging plain studs or pins 111 that extend laterally outward from crank arms H2 tixed to a rock Shaft 113 that has bearings in the sides of the base. Arms 1H rigid with the rock shaft and extending forward are provided with rollers 113 that underlie and are opcrative by shift key levers 146. The operation of either shift key lever rocks thev shaft 113.

thrusts up the links or bars 110 and shifts the segment 139 together with the type bars thereon to upper case position.

The me that supports the universal bar comprises a segmental body portion 117 having lateral extensions 118 provided with bearing pins 1-1!) that bear in brackets 150 fixed to the stationary supports or posts 139. A guide rod 151 and two guiding pins 152 are rigid with the portion or frame 117 and extend rearward therefrom providing bearings for a universal bar frame 133 on which is mounted a curved universal bar proper 15-1 that is operative directly by the type bars. The universal bar frame is provided with a restoring spring 155 and connected by a link 156 with an escapement dog carrier 85". conventionally shown. A center type guide 19 of ordinary construction is fixed to the frame 117. 118 and shifts therewith. The type endsof the type bars coiiperate with said guide. All forms of the invention may be provided with center type guides if found desirable.

The means for shifting the universal bar 151 and its supporting frame comprise uprlght'arms 157 plvotally connected by shoulder screws 158 to the side portions of the frame-117. The lower ends of the arms 157 are formed with eyes which receive bearing blocks 159 that are held in place by caps 160. These bearing blocks are provided with downwardly extending lugs 161 having rounded heads and said bearing blocks are perforated to fit loosely over the .studs 111 outside the links 110. The studs terminate just outside the bearingv blocks when the latter are in normal position and stationary pins or .rods 162 fixed to the sides of the base .and projecting laterally inward therefrom in register wither in line with said studs terminate just-short-of the studs leav' ing a slight space between them so as not to interfere with the up and down movement of said studs when the rock shaft 113 is -rocked. These rods 162 are of the same diameter as the studs 111 and are adapted to receive and support the bearing blocks 159 when the latter are slid outward by means presently to be described for the purpose of disconnecting the universal bar from the case shiftingmechanism.; The ends of the studs 111 and of the rods 162 are preferably beveled or tapered slightly to facilitate the lateral disconnecting and re-connecting movements of the bearing blocks and the arms 157 which carry them. The disconnecting-means comprise levers 163 and 161 pi'voted at 165 on angular brackets 166 screwed or otherwise secured to the base frame 13.7 and extending inward therefrom.

The pivots 165 are below the lugs 161. The' right-hand lever 163 is a bell crankand has lever arms 167 and'173j are operatively connected by a link or rod 171. The construction is such that when the special key 'lever' 171 is operated the extension 170 thereon acting against the arm 169 will rock the bell stud 111.

a downwardly-extending arm 173- The crank 163 and through the rod 171 will also rock the lever 161. The u'pwardly extending arms'ot' said levers nil swing outward away from each other and will act to shift the l)ttll'lll; blocks 15) laterally out-ward on to the stationary pins 162. thus disconnecting the rods 1.37 from the studs 111 as indicated by the dotted lines in Fig. 11. Following such disconnection it will be understood that an operation of either of the 'sh-it'tkcy levers 116 will be etl'ectiveto shift the type bar segment 139 but not the universal bar 151or its carrier frame 117. these parts remaining down in lower case position.

In order to restore the parts to the lirst position means are provided comprising 'a sleeve 1T5'that is slidably mounted on the left-hand rod 162. Connected with the slide or sleeve is a push rod 176 that passes through a somewhat larger opening 1TT in the left-hand side of the base 137 an d is provlded outside the base with a key or button 178. A coiled spring Nil-anchored to said ward the left. its movement in this direction being limited by a stop 186 on the rod 171'. This stop arrests the sleeve in such position that its right-hand end is close to the lefthand bearing block 136 when the bearing blocks have been slid on to the rods 162. Consequently lrvpushingin thekey 17.8 at this time the sleeve will contact with the said base tends constantly to draw the sleeve toi left-hand bearing block and force it back on l to its stud 111. This movement of the bearing block operates through its lug 161 on the train of devices comprising the lever 161. link 1T1-and lever 163 to restore the righthand bearing 159 to engagement with its ()n releasing the key 178 the spring 179 will restore the sleeve to' its lefthand position. A'stop device 166 may be provided having stop portions above and below the lever arm 169 to limit its move ments in both directions and thus limit also" the movements of the devlces with which it is connected and which it controls.

A modification of theconstruction of Figs. 1116 is illustrated in Fig. 17 wherein the lever 171 is replaced by a lever 181' pivoted at the rear of thebase and provided with the usual restoring spring and finger key. Said lever 181 is provided with a downward extension 182 which at its lower end is formed with .a slot indicated at 183 in which is loosely engaged, the lever arm 169. \Vhen the key lever 181 is depressed the top of the slot 183 engages withthe lever arm to rock it and swing the right-hand bearing block159 on to the 'rod 162. time through the link 171' the lever 161 is to its inoperative position on its rod 162. While the lever 181 is maintained depressed by one finger the operator may, with a finger of the same hand, depress the right-hand At the same i v caused to swing the left-hand bearing block shift key which is in juxta'osition to the key of the lever 181. This eaves the lefthand free to operate the printing keys. On releasing the key lever 181 its spring will restore it to normal position and the bottom of the slot 183 engaging with the under side of the lever arm 169 will operateon the train of devices starting with said'lever arm to restore the bearing blocks to their studs. Preferably the key lever 181 is provided with. a locking key of a suitable construction, such as that found on the left-hand shift key lever of the No. 10 Remington machine, by which said key lever maybe loc ed down to maintain the universal bar. 14; withdrawn from the control of the' shift key mechanism as long as may be desired.

It will be observed that in the Fig. 8 construction relative displacement is afforded between the links that extend to the shiftable frame that supports the universal bar and the lateral pins or studs on' the key controlled rock shaft, this displacement'being caused by a downward movement of the links by means comprising the accent key lever. On the other hand, relative displace ment between the corresponding parts in the Fig. 14 construction is afl'orded by a lateral movement of the ends of the links lengthwise of the pins or studs, this lateral movem'ent being caused by means comprising a special key lever.

It will further be noted that the center guide illustrated in the Fig. 14 construction is supported independently of the case shifting element or type bar support: that said center guide is shiftable simultaneously with said element to change the case position; and that said center guide is also shiftable independently of said element, said center guide and the support on which it is mounted which is also the support of the universal bar being shiftable from upper case back' to lower case position while said element or typebar support remains quiescent.

It will also be understood that as far as the generic features of my various improvements are concerned the universal'bar construction, mounting, escapement mechanism, type bar actions and the type bar shifting devices may each and all be specifically different in construction from the several specific constructions herein shown and described.

Features specific to the construction shoyvh in Figs. 14 to 17. inclusive. are not claimed herein as they form in part the subject-matter of divisional application Sr. No. 81,616 filed March 2. 1916.
