TYEE WRITIILJG MACHINE.-

To all whom it may concern Be it known that I, 1)}HL1PPE on GLAIIECY, a citizen of the United States, and a resident of Boston, county of Sutlol'k, and State of lilassachusetts, have invented certain new and useful. lmproven'icnts in lype-llritingr hlachines, of which the following is a full, clear, and exact description.

This invention relates more particularly to a foldable't'ront strike or other visible typewritingmachine.

One of the, principal objects of the in vcntion is to provide a typewritinn machine in which the platen carriage and its direct support may be folded rearwardly and downwardly within the main tranuor main frame part of the machine and the keyboard folded upwardly and inwardly also within the main frame or main frame part thus confining); substantially the entire mechanism within the i'nain frame part oi the machine in order that the working parts may be protected as well as the machine made compact and convenient for transportation purposes.

Another object of the invention is to pro vide a type-writing machine in which keyoperated levers comprising two parts may be both mounted upon a common rod or axis and so constructed as to form a knuckle or knee-joint in order that one part of each key-operated lever may told with respect to the other part without disconnecting the parts.

Other objects of the invention are to pro vide a keyboard frame part which is toldable upwardly with a part of the key-operated levers and means whereby the toldable parts of the lniy-operated levers may be locked and held to said keyboard frame part; to provide a machine wherein upwardly and rearwardly moving type-bars are employedand which type-bars are actuated by relatively toldable parts of key-operated levers; to provide simple means as an eseapenientmechanism for typewriting machines: to provide simple operating mechanism for imparting a lengthwise step-by-stepteed to a ribbon; to provide means whereby ribbon spools may be ii'rictionally held; to provide a ribbon holder which may move to and from the platen; and which when the platen is Specification of Letters latent. lPg tguyg fl 5 1% 1918 Application filed. fliarch 4, 1916.

given a compact movement is adapted to fold automatically to a compact position; to provide simple means for releasing the escapement to adapt the carriage to move freely along the carriage bed; and to provide simple and etticient line-spacing mechanism for the platen.

A further object of the invention is to provide simpleand c'llicient mechanism for shitting the platen and carriage to adapt the type-bars to have a plurality of type or characters thereon.

A still further object of the invention is to provide means whereby the ribbon feed and the cscapemcnt mechanism may be simultaneously operated by the universal bar.

Another object of the invention is to provide a typewriter in which the type basket and type-bars may be moved bodily from a normal operative position to a more com pact one.

A still further object of the invention is to provide a machine "which is simple in construction, which may be readily made and assembled, and which when compact provides a substantially uniform package.

llith these and other objects in view, the invention will be hereinafter more particularly described with reference to the accompanying drawings, which form a part of this application, and will then' be pointed out in the claims at the end of the description.

In the drawings, Figure 1 is a front elcva. tion of one form of machine embodying the invention.

Fig. 2 is a longitudinal section, partly in elevation. of the machine.

Fig. 3 is a plan view partly broken away.

Fig. at is a fragmentary view, partly broken away and partly in section, showing a part of the means for operating the escapement and the ribbon feed mechanism.

Fig. 5 is an enlarged fragmentary side elevation of a part 01" the escape-men's operating mechanism.

Fig. 6 is a side elevation of a partof the cscapement actuating means shown in Fig.5.

Fig. 7 is a fragmentary enlarged view showing one kind of joint for the two parts of the key-operated levers to adapt both parts in one position to operate in unison and to permit relative folding between said parts. v

Fig. 8 is an enlarged section, partly in elevation, of means for holding the platen carriage support in its normal operative position; and V Fig. 9 is a View similar to Fig. 2, partly diagrammatic,showing a construction wherein the type basket and type-bars may be 1n0\'fi(l,fl'0li1 a normal operative position to a compact one below the upper surface of the main frame or main frame part.

llhe main frame. or main frame part 10 has upright corner pillars or posts 11 with the usual rubber tips or feet 12 and connecting the posts at the lower portion thereof is a base 13. At the upper portion of the main frame part is a top plate or member 1st and. there may be side plates if desired, it being understood that the frame or main frame part, may be of the usual or of any preferred construction. Ali the forward portion of the. machine is a luzyboard frame part 1.5. This keyboard frame part 15 is hinged atltl to the main frame part and at the outer portion thereof may be provided with rub her feet of the usual kind. The keyboard frame part is tray-like in form and is adapted to fold upwardly and inwardly as shown in dotted lines in lfig. The hinge or pivot 16 is in the form of bolts located on opposite sides of the mainframe part in alineineni, and said bolts have threaded stems which are engaged by thumb nuts 17 which assist in holding the keyboard frame part in its folded and in its normal operative position. This luayboard frame part 15 at its inner portion is provided with an abutting surface 18 which adapted to engage a substantiallyL-shaped spring 1f) secured to the frame base 13 so as to position and hold said frame part in a normally horizontal position, and in the folded position of said frame part the latteris retained in such position by means of a spring 20, one end of which is secured to the under surface of the frame part 13 or otherwise held as desired, the thumb nuts 17' serving as additional holding Il'lQtlllS for said frame part.

A l-zeyboanl if is mounted to move with the keyboard frame part 15. This keyboard may be of a universal or standard kind and con'iprises keys 22 which are arranged in banks or groups and are mounted upon the upper ends of vertical portions of levers 23. 'lhe'levers 23 are each formed in two parts 24; and The parts 2%. and 25 are in alinement when in a normal operative position and all of the parts of said levers are pivotally held to a transversely extending rod 26. The rod 26 is held in a main frame part of the machine between the forward corner posts 11. of the main frame part or in any other desired way. The parts 25 of the keyoperated levers extend horizontally and are in alinement with the horizontal port-ions of the parts 24:, and on one of said parts, as the part 24: of each lever, is a shoulder 27 which is adapted to engage a shoulder 28 of the part 25 when in normal operative position as shown in Fig. 2, so that on the depression of one of the keys the inner end of the-part 25.0f the two-part lever on which the key is mounted will be forced upwardly. Each lever 23 is restored from a depressed position to its normal operative position by a spring 29, one end of which is secured to the base 13 and the other end passed through an aperture in the key lever part The

shoulders

27 and 28 and the mountings of the parts 2% and provide a knee or knuckle joint which adapts all of the parts of all of the key-operated levers to fold relatively to the parts as shown in dotted lines in Fig. 2.

The inner ends of the parts 25 of the keyoperated levers 23 have a pin 30 and each pin is adapted to move in a slot 31 of an arm 32. The arm forms a part of the bellcrank lever and each bell-crank lever is pivotally held in a bracket 3: extending upwardly from the base 13 or to a common pivot rod as preferrtal. The arm of each bell-crank lever is pivotally held by a knee or other joint at its outer end 36 to an upwardly extending link 3'7, and said link a 37 at its upper end is pivoted at 39 to the short arm 40 of a. type-bar 41. Each typebar it is adapted to have a plurality of type or characters thereon according to whether a single case shift. or double. case shift is employed. The type-bars are adapted to rest at their forward ends upon a felt, rubber or other cushion 42 and are arranged in a curved path within the type basket 41:3, said type basket being suitably held in the main fran'ie part of the machine in such a way that when a key-operated lever is moved on the depression of a key, the actuation of its cooperating bell-crank lever will force a link 37 downwardly and this will cause. one of the type-bars to move the type upwardly and rearwardly to make an impression upon the work sheet about the platen etat'in the usual way.

As a means to lock-the keys and the foldable parts of-the key-operated lovers to fold and unfold together, a bar &5 extends transversely of the machine over the parts 24. and under the parts 2% is a substantially U-shaped rod 46. The rod L6 is pivotally mounted. between the sides of the shallow frame part 15 and is adapted to be forced the transversely extending bar to and the portion l7 and thereby prevent their disarrangement. The bar 45 may have a rubber or other strip forming an engaging surface for the key-operated levers, and the rod 4:6 may have a knob or handle to move the same, it being understood that the key-lever parts 24 are not held so tight between the bars 46 and l? as will prevent such relative movement of the keyboard frame part and the key-lever parts as as is necessary because of their difierent pivot points.

The platen l-l is mounted upon a platen carriage 48. This platen carriage s8 is adapted to travel transversely of the ma chine on a foldable support d9. This support .49 has two members 50 and 51 which are hinged together at 52 at the upper poi;-

' tion of the machine. The support member 51 rests when in a normal operative position upon a transversely extending bar 53 forming a part of the vertically movable member 50 of the platen carriage support. The platen carriage may be variously constructed, As shown it comprises end pieces or brackets 5d which extend upwardly from p a carriage base 55 and said base may be held to' travel. transversely of a carriage bed. The carriage bed may extend rearward as far as the hinge 51 or'may be supported between foldable arms or in any other desired Way. The carriage end piecesb l support the axis or shaft 56 of the platen and said end pieces may also support a paper apron 57 in which may be mounted a pressure or teed-roll 58,

there being paper fingers and such other parts as are usually employed to hold and guide the work about the platen.

While the platen carriage with its bod forming one member of the carriage support is adapted to fold rearwardly and down wardly so as to extend within the main frame part 11 and between the sides thereof when in a compact position. as shown in dotted lines in Fig. 2, the platen carriage and both members of the support are adapted to be shifted for upper case characters :when in a normal operative position, though it will be understood. that the platen carriage may have two shift movements instead of one, or the type basket itself may be shifted as in some forms of writing ma chines, if desired. The movable carriage support member 50 at each end has upright portions 59 and these portions 59 have a tongue and groove or other connection with the sides oi the main frame part 11 or otherwise held to move vertically thereon so that in its vertical movement the platenv carriage with its bed 54 will partake of such vertical movement. A pin or stud 60 projecting inwardly from each side of the main frame part 11 enters a slot 61 in each carriage support portion 59 and adapt- 13. An arm extends upwardly from the shaft 63 at each side of the machine and connected to each arm 65 is a link 66. Each link it is connected to an arm 67 of a bellcrank lever which is mounted in. the bracket on the same rod as the bell-cranks 33 are mounted. A shift lever (58 is located at each side or the machine so that the platen carriage may be shifted from either side of the keyboard, and each shift lever comprises two parts 59 and 70, which have a knee joint connection similar to the keyoperated levers 23 in order that said shift levers may have one part fold relatively to the other part and the toldable part thereof movable as a part of the keyboard when the keyboard frame part is folded to its compact position. The parts 70 of the shift levers are adapted to operate the bell-crank arms 67. These arms or either of them oper ate the links 66 and the eccentrics G2 on the depression of the shift keys, and this movement of the eccentrics (52 forces the carriage support men'ibers 50 and 51 to place the printing point and the platen in position for writing upper case characters.

The platen carriage and its support may be held in its normal operative position against relative backward folding movement in any desired way. As shown, a pin or stem 71, Figs. 3 and 8, has a knob or head 72 thereon and is normally forced inward by a spring 73. The pin 71 is adapted to engage an aperture 74 in one end of the carriage bed or other part and lock said bed to the vertically moving supporting member 50 so that the platen carriage cannot fold rearuuirdly until the pin is released. The platen carriage may also be held against a swinging or free movement when in its folded compact position. by a releasable pin or part 74 or otherwise, which is held to the frame of the machine and is adapted to engage under a part of the foldable carriageor guides 7 7. The universal bar is normally forced downwardly in the path of the keylevers 23 by springs 78. The universal bar has inwardly extending arms 79 and these arms extend upwardly, as at 80, at opposite sides of the machine. At the upper ends of the parts 80 are heads or slides 81 and 82.

These heads 81 and SQ'are suitably guided at their upper ends by brackets 83 or other wise, and said heads are adapted to engage rollers Sat and respectively, both of which are mounted upon a transversely movable rod 80. The rod 86 is suitably supported in the machine frame and is normally forced against the action of the

heads

81 and 82 by one or more springs 87. The heads 82 are each provided with a straight portion 88 forming a normal seat for the rolls 85 and a beveled or inclined part 88 forming a wedgedike actuating part on each had. livotally held to each head is a pawl or dog 85). The pawls 80 have their free ends normally torced outwardly beyond the heads to provide teeth 00. and each tooth is adapted to move inwardly within a recessed part of the head during the upward movement of the heads and rods 80 on the depression of the key-operated levers. A spring 01 tends normally to force each pawl 80 out wardly or permit the pawls to be moved inwardly during the upward movement of the heads. The upward movement oi? the heads will cause the rolls and rod 80 to move transversely of the machine to a point indicated by the first dotted line of roll as at 01, Fig. As the pawls89 are forced above the rolls 8t and owing to their being held. to yield, they will not operate said rolls but immediately that the teeth ol? said pawls are above said rolls the teeth or ends 00 thereo't will engage the upper portion of the rolls, and during the dowi'nvard movement ol the universal bar and heads 8:2.an additional' throw will be given to said rod 80 to the point indicatcdby dotted roll 01, said pawls' being each held against upward movement by means of,a stop or part 02 located immediately above said pawls. Two lugs or projections 93 which are spaced apart and project rearwardly from the transversely movable rod 80 are adapted to span an arm 9-1 of an escapement detent or arm 95. The detent 95 is pivoted at 90 and has a retaining tooth or dog 97 and a longeutooth or dog 98 which are adapted alternately to engage the teeth of arack 00 by reason of the reciprocatory n'lovement of the rod 80. The dog 98 is released during the additional throw given the rod 86 by the pawls S9 and this will place the (log 97 in engagement with the rack, said dog 07 being" released on the return. movement of the rod 80 and the universal bar. The rod 86 may be operated aerate-i instead of partly on the upward movement of the

heads

81 and 82 thus avoiding any lost motion-between the projections 93 and arm oi the detent 95, in which case said heads do not move the rod 86 on their upward movement and the we lee portions are dispensed with. The rack 9?) is supported under the platen carriage and may be pivoted .at one end, as at 100, to adapt the escapement rack to be released from the escapement dogs, as will be presently described. The platen carriage is normally under tension of a spring in a drum 101 mounted under the carriage supporting members .to shift therewith and is adapted through the usual strap or connection to move the carriage a letter space each time the universal bar is operated, though instead of the particular form of mechanism shown a limbcr and a fixed dog adapted alternately to engage the rack teeth, as is common in many forms of typewriting machines, may

be employed and operated by the rod 86 or- By having the in any other desired way. universal bar actuate the reciprocating bar 80 on its downward movement rather'than ils upward movement the letter feed moveafter the type have moved against the work on the platen; otherwise the carriage might move at or about the time an impression is made hy the type. The rod 86 may be made to reciprocate from right to left instead of left to right to release the escapement, in which case the dog 97 will normally engage the rack; The

heads

81 and 82 will in that case be reversed.

It will be evident that the escapment dogs and racl; which are both mounted upon the platen carriage support may by reason of the arm Ell resting between the projecting lugs or parts 03 on the transversely extending rod 80 be separated therefrom when the platen carriage and its supporting bed are moved to a compact position, and on the platen varriag'e being restored to its normal operative position the arm 94: will automatically position itself between said lugs or projections 03 ready to be operated when the keys and universal bar are operated.

The carriage may be letter spaced without printing in any suitable way. The space bar 102 is connected to level-S103. These levers 103 are divided into two parts, 10st and 105, and said two-part lovers are mount ed upon the transversely extending rod 26 and have a knee-joint connection similar to the key-operated lovers 23, so that the space bar and the forward parts 103 of the twopart levers may fold as a part of the keyboard. The inner parts 105 of the key operated levers simply actuate the universal bar and have no connection whatever with any of the printing instrumentalities,

arass-1 The ribbon holder 106, is located substantially centrally of the machine and is adapted to support a ribbon in position to cover the printing point on the platen 14.

The ribbon holder 100 is pivoted 107 to a part of the main frame and on opposite sides of the holder, adjacent to its pivot 107, are springs 108 and 109. The spring 108 is secured to the foldable part of the carriage supporting member 51 to fold therewitl'i while the spring 100 is held to a fixed part. The spring 108 is of greater strength than the spring 109 so that when the spring 108 is in the position shown in Fig.2 the holder will be held against downward folding movement, but when the spring 108 is folded away from the holder 106 to the position shown in dotted lines in said figure the spring 109 will force the holder rearvv ardly and downwardly on its pivot to a compact position. That is, the ribbon holder will fold over to a substantially horizontal position, carrying the ribbon held thereby and may be restored to. its normal operative position manually or otherwise when the platen carriage is restored to its normal operative position. The ribbon from the holder 106 passes about ribbon spools 110 and 111 mounted upon downwardly extending arms 112. The ribbon spools may be detachably held to permit the ribbons to be readily re placed and said ribbon spools may each be frictionally held to its support against too free movement by a spring 113 which may be in the form. of a strip or as a disk as preferred. he ribbon spools may have a toothed disk portion or ratchet wheel 11% as a part thereof and adapted to engage the teeth of the ratchet wheels are pawls 115. The p'awls 115 are mounted upon inwardly extending arms 110 held to the vertical rods so that during the reciprocation oi? the universal bar and parts 80 the pawls 115 will impart a rotary step-by-step movement to the ribbon spools to wind the ribbon from one spool on to another.

While the drawing shows both pawls 115 in engagement with the teeth 0? the ratchet wheels of the ribbon spools only one pawl is in engagement at a time, and these pawls may be moved to engagement or disengagement manually and imlependcntly or they m y be moved simultaneously as is common in some forms of tvpewriting machines,

whereby one pawl is disengaged when the other pawl is engaged in order that the direction of feed of the ribbon may be reversed at will. The ribbon ti-ed thus operated simultaneously with the movement of the means for tri ipinn the escapement, the ribbon teed being actuated during one move ment of the universal bar and the escapement mechanism durim the return move ment of said lllllYil'Sill bar. The pawls 115 F"? sill and the direction of teeth of ratchet disks 11 1 may be reversed to permit the spools to be rotated during the downward movement of the universal bar instead of the upward movement.

The carriage may be released to permit the same to move freely along its bed. As one means a bell-crank lover 116 is piV0t ally held to one of the carriage end brackets 51. This lever 116 is pivoted at 117 and has one arm. thereof formed as a finger portion 118. The other arm of said lever is slotted as at 119, to engage a pin 120 on the carriage rack. This pin 120 is slidably held in the carriage end bracket and is normallyiorced in one direction by a spring 121 arranged in said slot, said rack, as before stated, being pivoted at one end thereof and at its end opposite the part eneagcd by the lever 116. As the lever 116 is depressed the rack will be shifted to one side and be released from the teeth of the escapemcnt dogs thus permitting the carriage to be moved freely in either direction along the carriage bed.

As a line-spacing means for the platen 4A a ratchet wheel 122 is provided on the platen shaft 56 at one end thereof. The teeth of the ratchet wheel are adapted to be engaged by a pawl 123. The pawl 123 is mounted upon a lever 121 which is pivotally held to the platen shaft 50 and is adapted to move about said shaft independently thereof, and during such movement will cause the pawl 123 to engage the teeth of the ratchet wheel and rotate the platen 4 1. A segment 125 is held to or formed as an extension of one of the carriage end brackets 5.4, and said segment is slotted as at 126 and in said slot is held an adjustable stop 12?, as a bolt and nut. lhis stop 127 may be variously positioned in the segment and controls the distance the line-spacing lever 12% is adapted to move. By adjusting the step 127 the pawl 123 may be made to move the ratchet a single space or two spaces or more, according to the distance the lever 12% adapted to be moved on its axis. The platen is thus adapted to be line spaced varying degrees.

The operation of the invention will be readily understood from the foregoing description when taken in connection with the accompanying drawings. The parts being in the position shown in the drawings, it will be evident that if the keys are operated the key-levers will be also operated and the inner portion of the key-levers will move the bell-crank levers 33, links 37, and type-bars 41 to make an impression on the work sheet about the plat-on n. During the movement of the key-operated levers the universal bar will be operated and the upward n'iovemcnt ot the universal bar with the parts 80 will aciir its the ribbon feed mechanism on the upward movement thereof and on the return movement of the universal bar the escapement dogs will be tripped through the action of the heads 82 as already described. lhe platen carriage and its supporting members may be given a vertical shift moven'ient by means of either one of the shift keys, the carriage and its supporting means being restored to its normal position on the release of said keys by springs or otherwise. If the machine is to be made compact. for t ransportation, the retaining pins '71 may be released which will permit the foldable member of the carriage support and the platen carriage. with the spring 108 to be folded retn'wzn'dly and downwardly, as shown in dotted lines in Fig. 2, and the keyboard frame part. 15 with the parts 24 of the key-operated levers, the space bar and the shift keys may be also moved to a compact position, as shown in dotted lines in said figure.

In Fig. 9 the construction of the machine is substantially identical with that already described, except that the type basket, typebars and part of the type-bar action is constructed in such a way that the type-bar basket may be moved below the upper surface of the frame, so that no part of the typewriter mechanism will extend above said surface when the machine is compact and in its transporting condition. The construction is shown in Fig. separately from that of. the disclosure in Figs. 1 and 2 in order not to confuse the parts, and it is to be understood that this construction may be embodied with the mechanism and parts shown in Fig. 2 orwith any other suitable mechanism. As shown in this ligure the type basket 128 is supported by uprights or standards 129 which have a pin-and-slot connection as 1 -30 to adapt the type basket to lower to the position shown in dotted lines.

The type bar basket. may be engaged when in a normal position by a latch or catch 131 which is normally pressed to an engaging position by a spring 132, and which may be readily released by the operator so as to adapt the type basket to lower. The typebar operating levers 132 are made in two

parts

133 and 134 which have an elbow or knee joint as 135, to adapt the links to as sumo the. position shown in dotted lines when the type basket islowcrcd. 'lhe joints between the parts 1 -13 and 134 of the links are such that when in the position shown in full lines a positive connection is made between the type-bars and the bell-crank levers 135, said levers 1 -35 being operated by the key-operated lovers in the same manner as already described.

From the foregoing it will be evident that a simple and ellicicnt. typewriting machine is provided wherein the keys forming a part of a universal keyboard and the platen carriage may be moved or folded to a more conlipact bosition when not in use than when in :li normal operative condition; that simple and efficient means are provided whereby the foldable part of the keyboard may be retained or locked against movement during such folded movement; that means are provided whereby the type basket may also be moved to a compact position; that simple and efficient. ribbon mechanism is provides; that a separal'ile escapement mechanism is provided whereby the platen carriage may fold from a normal operative position to an inoperative and compact one and the connection with the escapement mechanism again effected without adjustn'ient of parts; that simple case shift means is provided; and that said machine is simple in construction and may be readily made and assembled.
