yto a front strike or other visible typewriting machine in'which the cubical dimensions o f the'machi'ne may be materially reduced when not in use to adapt the machine for transportation and other purposes.

One of 'the principal objects of the invenv tion is to provide'a typewriting machine of a small portable character in which the keyboard may be 'extended when in a normal operative position and which may be moved bodily and entirely inclosed within the main supporting portion of the machine so as to makethe machine compact While not in useand provide a package which is substantially uniform to permit it to be conlveniently carried as a part of a persons luggage Vin traveling or otherwise, and which, in the compact position, has the keyboard protected against injury.

Another' object of the invention is to provide a writing machine which has the general appearance of a large standard bar typewriter when in use, and which may be collapsed or have parts thereof'moved to a more compact position when not in use than when in a normal operative position.

Other objects of the invention are to provide simple mechanism whereby a separable operative connection may be made between the keys and the type-bars of a type-writing; machine to permit the keys to be moved bodily inward when not in use and to be automatically positioned to operate the typebars when in an open or extended position; to provide a machine in which the keyboard may be of a standard or universal character and in which the key-operated levers, the space bar and the shift levers, where more than one is used, may be moved bodily inward to be inclosed within the frame or support of the machine as a unit without any vdisarrangement; to provide -simple means whereby a separable two-part key-operated lever connection may be made with type-bars to permit the complete separation between one part of each key-Cperated lever and the other part; and to `provide a writing machine of simple constructionwhich may be readily made andassembled.

A further object of the invention is to provide a machine wherein the platen ,carriage Vribbon mechanism and escapement mechanism or either of them may be given a horizontal-movement relatively to the type and simultaneously and automatically moved during the compact or extended movement of the keyboard. l

A still further object of theinvention is i to provide simple means whereby a platen carriage may be .given a compact sliding movemlent in a direction different from the shift and letter-spacing movements.

Vith these and other objects in View, the invention will be hereinafter more particularly described with reference to the accom panying drawings, which form a part of this application, and will then be pointed out inthe claims at the end of the descrip. tion.

ln the drawings, F igure l is a plan view,

partly broken away, of one form of machine embodying the invention.

Fig. 2 is a vertical longitudinal section of the machine taken on the line l-H of Fig. l, the carriage and certain other parts. being shown in elevation.

Fig. 3 is a view similar to 2 except that the parts have been moved ,to a compact position.

Fig. 4 is a fragmentary sectional plan view showing one form of the means wherebyv a standard or universal keyboard may be mounted to move bodily and as unit from an extended or open position to a compact position.

'Fig 5 is a detail elevation of the telcscopic sections or parts whereby the keyboard is mounted for horizontal compact movement.

Fig. 6 is a. transverse section showing the dovetail connection between the several parts or slides of the keyboard member.

Fig. 7 is a fragmentary vertical. elevation, partly in section, showing the means whereby the carriage and the parts for operating the escapement mechanism may be moved horizontally with the carriage in its com Fig. 9 is a vertical elevation, partly in section of a part of the platen shift mechanism.

Fig. 10 is a vertical section, partly in elevation of a part of the shift mechanism; and

Fig. 11 is a view showing how the machine instead of being mounted on an ordinary frame may have the mechanism thereof mounted upon an inclosing case which serves as a frame and support.

While the invention is shown as applied to a particular form of typewriting machine, it willybe understood that the principle whereby the machine may be made compact may be embodied in writing machines of various kinds orv constructions.

The support or frame 10 comprises a main supporting member 11 which is normally stationary, and a relatively movable keyboard member 12. The main member 11 has a rear wall 13, a front wall 14, and side walls 15 and may be made of any suitable material, as sheet metal, and may be of any suitable shape, either box-like in form or of any rother desired shape. The keyboard member 12 comprises a substantially rectangular skeleton-frame-likel part 16 having sides 17 connected together by a transversely extending narrow bar-like front portion 18. Connected to each side 17 is a slide 19 comprising two telescopic or movable members 20 and 21 and a fixed member 22, which latter is secured between the front wall 14: and the rear wall 13 of the main member 11 or in any other desired position. The member 2O is provided with a slot 23 in which a pin 24 projects from' the slide member 21 and in said member 21 is a slot 25 in which extends a pin 26 from the normally fixed member The several slide members permit outward and inward movement of the keyboard member 12 and lare held together and limited in their relative movement, each member being properly guided during the extended and compact movement. he member 20 has a dovetailed connection with the member 21, as shown in Fig. 6, and the sliding member 21 has a dovetailed connection with the fixed member 22. It will be evident that the keyboard member 12 may be moved relatively to the fixed member 1l of the frame or supportv'so that in its extended position the front bar 18 will be located some distance forward from the front wall 1iv ot said fixed member, and when moved to a compact position as shown in Fig. 3. the bar 18 may bemade to lie substantiallyy flush with the front wall 1e and the rest of said member 12 located entirely within the member 11, said front wall 14 being cut away to permit the compact or extended movement of said keyboard member.

On the member 11 are a porting rods 27, 28 and 9. These rods explurality of sup- 4 ble case shift is provided, either form being of a standard or universal character. The levers 30 to 32 each have a key 33'0r operating said levers and each key-operated lever is substantially of a bell-crank form. One arm, as 34, of each lever carries one of the keys 33 and said arms ,'34 of the different groups are of relatively different lengths, the arm 34 of the Lowest group being the longest and the keys located at a greater distance from the fulcrum rod on which the key-operated levers are supported. The arm 35' of each key-operated lever extends upwardly, and these arms have their outer ends bent at an angle as Yat 36 and are each adapted to engage the inner lower edge of an arm 37 of a substantially bell-crank lever 38, said arms 35 of the differentgroupsbeing of different lengths to compensate for the diiiierent lengths of the arms 34 in order that a substantially uniforn'i `touch may be provided. Each lever 38 is mounted upon a transversely extending rod 39, about which said lever is adapted to move. The levers 38 and the levers 30 vto or either of them if made of sheet metal may be bent so as to Storm spaced bearings about' the fulcrum rods. The levers 30 to 32 may each be held in a normal operative position by means of springs 39a one end of each ot' which is attached to the lever arm 35 and the other end of each spring is passed through an aperture in the transversely extending rear bar 40 of the keyboard frame 12, while the levers 38 may be held in their normal position by means of springs el, one end of each of which is attached to the longer arm of each lever 38 and the other end of each spring 41 held in an aperture in a transversely extendingy angular bar 4:2. The levers 38 and the keyoperated levers 3() to 32 thus form substantially a two-part key-operated lever which are so mounted as to provide a complete separable connection between each arm 37 and its coperating zii-m35, there being a keyboard is forced into the frame member 11'.

Wlan any one of the key-operated levers Levante 30, 31 or 32 is depressed by the operator7 i' the arm 35 of such lever will be forced forward and such forward move-ment will engage-the downwardly extendingarm 37 of its coopera-ting lever 38 so as to move the inner end downward when the keyboard is in the normal operative position shown in Fig. 2. lt' the machine is to be made compact, the keyboard member l2 may be forcedv inwardly which will carry all of the keys land key-o] )erated levers to mounted movement of the keyboard member and keyof the levers 38.

board a. complete separation takes place between-the arms and 37, while when the keyboard member is moved to an extended position the arms 35 are automatically brought into position to operate the arms 37 A number of type-bars 43 are provided, there being a type-bar for each lever 38. These type-bars 43 are ypivoted atl to a segment or other supporting means t5 and at .their outer ends are provided .with type heads or blocks 46 on which are a plurality of type the number oflwhich depend upon whether there is a double or single case shift.

The type-bars each have a lugvor projecting' portion 47 which is connected by a link 48 to the rear end or part of each lever 38, thus when the levers 38 are operated through the keys 33 as already described, the typebars will be pulled upon so as to force the type lor types upwardly and rearward against a platen t9 mounted in a transversely movable carriage 50.

The platen carriage 50 may be of any suitable construction. As shown, itis substantially the same as embodied in the Coi 'rena portable typewriter, and is adapted to travel transversely of the machine on a carriage bed 5l. The carriage bed 5l is held upon bars 52. There are two bars 52 located on opposite sides of the machine, and 'said bai-sare slidably held to other bars 53. The bars 53 are also arranged in'pairs and may be slidably connected to the bars by suitable dovetailed tongue and groove connec- 'ith a foot portion 57.

tions or in any other desired way.l The bars 52 on which the bed 51 is mounted and which are located on opposite sides of the machine are connected by links 5l to levers' The levers 55 are vmounted on the transversely eXtending'rod 39 and their-lower arms 56 extend atan angle and are each provided The arms 5G arc each adapted to be engaged by the keyboard trame 16 of the member vl2, as the saine moved inwardly and in doing se will rock the arms 5G and cause the feet 57\to ride upon the upper edge of the sides ot' said keyboard member shown in Fig. 3. This y movenmnt of the levers will cause the links 5l to move the side bars 52 relatively to the bars thus carrying the bed andcarriage and whatever parts are mounted on said bars from an overhanging position as shown in Figo 2 forwardly to the posit-ion shown in Fig. 3 wherein the carriage is located directly over the main or .'iXed member ll ot the su )ortinfr fame.

When the keyboard it'rame is extended the carriage is forced rearwardby means of one or more springs 58 one end of each of which is attached to the rear wall vof the support or fixed member and the other. end to one oi' the bars 52, though instead of the springs 58 the carriage may be connected to be moved positively rearwardly as well as forwardly with the compact and extended movements of the keyboard. The carriage and keyboard are thus moved bodily as a unit simultaneously in opposite directions 'to a compact position when the keyboard frame member is moved to such position, and when the keyboard is extended the carriage is also moved and automatically to its operative position in overhanging relation at the rear of the main ixed member ll. A pin 53a, Fig. 7 may' project from each ot the bar members 53 of the carriage support, and said' pins are adapted to enter slots 58,1 to limit the relative movements oi the members 52 and 53 it desired. l

A space bar 59 .is provided as a part of the keyboard and this space bar is carried by the space levers G0. The space levers G0 are mounted upon one of the fulcrum rods 27 to 29, preferably the lower one and has upwardly extending` arms which engage the arms ot' levers 6l mounted upon the rod 39. These levers 6l are similar to the levers 38, except at their inner ends said levers 6l have slotted ends 62 which are adapted to it over and form a guide for a universal bar 63. The universal bar G3 extends transversely of the machine and has upwardly eX- tending parts which are connected to bellcrank levers 64. These bell-crank levers are located at opposite sides ot the machine and are pivotally held' te .fixed brackets G4 located Anear the rear corners of the machine. The levers G4 have downwardly eX tending arms v6st" and these arms are adapted to enoage the' lower portion of levers G5 and form a break joint connection there.- with, said levers 65 beingpivoted to brackets 65 secured to the movable carriage supporting; bars To the upper ends of the levers 65 is held a transversely extending rod 56 vand this rod 66 is adapted to extend through slots in a rocking frame 67. This rocking; iframe G7 is substantially the saine .as in the Corona. typewriter and that diseov ioo

vmay be restored to its normal position. As

the levers '5 5 are operated to move the carriage and bars 52 transversely of the'ma chine, the rocking frame 67 will be permitted t rock on the transversely extending rod 68 by reason of the slots in said rocking frame and by l'reason of the mounting between the levers 65 and bell-crank levers 64 said levers 65 will move away from the bell-crank levers 64 during the compact movement, but when the carriage is moved toits normal operative position the' levers .As one means, a latch or member 69 isv will be again brought into engagement with the levers 64 in position to be operated by said latter levers. The levers 64 at one end may be extended beyond the universal bar and adapted when separated from the levers 65 tohave said ends engage stops 68a on the rear wall orn the frame to prevent the universal bar by its weight from dropping too far or becoming disengaged from the space levers.

The keyboard member 12 with all the parts mounted to move therewith may be locked in its extended operative position.

pivotally held at 70 in the keyboard frame portion 16. rlhis latch 69 has a key 71 at one end thereof and at the other end is provided with a notch 72 which is adapted, when the keyboard is in its normal operative position, to engage a part of the front wall 14 of the main member as shown best in Fig. 2. By depressing the key'71 the latch 69 will have its notched end removed from the front wall of the member 11 at which time the keyboard frame member 12 may be forced inwardly within the main member 11.

Any suitable means may be provided as ribbon mechanism, both for vibrating the ribbon to permit visible writing and for moving the ribbon lengthwise-across the printing point. As one means ribbon spools 78 are located on each side oi' the machine and are supported by the movable' bars 52 of the carriage support. Thesev spools may be rotated by gears 7drl and worms 78", the latter being operated through the rocking frame 67, the ribbon vibrating mechanism, not shown, being also operated by the rocking frame 67 or otherwise, to move the ribbon to and from the printing point or to permit the same to remain inactive in subrevente stantially the same manner as disclosed in the patent to Otto Petermann No. 1,121,044, dated December 15, 1914.

The platen carriage, as well as the parts supported by the bars 52 and 53 are adapted to be 4shifted vertically, though instead of a. platen shift a type segment shift may be employed without adecting the vprinciple by which the machine may be made compact. As shown, the carriage and the direct support therefor as well as parts mounted thereon are vertically shiftable. The carriage supporting bars 53 are held upon osts 74 which are suitably guided in the brac ets 64 at the rear portions of the machine frame and at their lower ends these posts are connected by the transversely extending rod 68. Levers orarms 75 and 76 extend from the fore part of the machine rearwardly, there being two levers on each side ol tne machine. As the machine is shown with a double case shift, each type block of each type-bar may have three type, one for the upper case, one for the lower case, and the other for figures or other charac-ters, though only one case shift may be employed il desired, the num@ ber of keys and type-bars being changed accordingly. rEhe outer arms 7 6 are secured to a transversely extending rod or shaft 77 and the inner arms to a sleeve 77aA arranged around the shaft and both sets of arms are operatively connected to move'the rod 68 and posts 74. An arm 78 extends upwardly from the shaft 77, and an arin 79 extends upwardly from the sleeve 77 a so that by operating one arm, as the arm 78, one movement is given to the platen carriage and support vertically, and by moving the other arm 79 a diierent throw to the support and platen carriage is given, there being a spring, not shown, if desired tending normally to force the carriage and its support'.

downwardly. On one pair of arms, as 75, are stops 80 while on the pair of arms 76 are stops 81. rlhe stops 81 are adapted to engage fixed stops or screws 82 on a part of the keyboard slides at opposite sides of the machine, while the stops 8O are adapted to engage stops or screws 88 also located on the keyboard slides. These stops are adapted to limit the movement of the arms, and

as said stops are of relatively different lengths, as are' also the stops 80 and 81, difyferent throws are given tothe platen carriage during the movements of the arms 78 and 7 9. The arms 78 and 7 9 are adapted to be engaged by arms 84 and 85 respectively, one arm, as 84, extending upwardly from and operated by a shift lever 87, while the other arm 85 is operated by a shift lever 86, each of which is providedwith a key 88 by which the lever may be depressed. The' shift levers 86 and 87 are substantially tl`- shaped in form, and are rotatably held upon the support rod 28 of the key-levers 31,-and

novarese each shift lever has a forwardly extending portion'89. The shift levers 86 and 87 are lin dependently movable and each forwardly 'extending' portion 89 of said leversl may have a hook portion 90 which is adapted to be engaged by the inturned end 91 of a pivotally held lock lever 92, said lock lever being pifvoted upon a stud 93 and having a finger-'portion 94 by which said lever may be moved on its pivot. If either one of the levers is depressed; it may be locked in such depressed position by means of the lever 92 engaging either or both hooks 90, and if it is desired to lockl both shift levers against movement the lever 92 is moved. so that the end 91 may engage under the hooks 90, thus preventing movement of both of said levers.l

In Fig. l1, the construction of the mechJ anism is the same-'as already described, butr instead of the frame or support being` independent of a carrying case the mechanism is supported directly by an inclosing case .wh ich forms a frame or supporting means' for the different mechanisms and may be of any suitable construction. The main. member 95 of the-case or support has a rear wall 96., side walls 9.7, a base 98 on which may be rubber feet 99, and a short front wall 100 over the upper edge of which the keyboard member 12 is adapted to move. A cap, top or cover 101 mayv be hinged 4at 102 to the main member 95 and is adapted to-swing backwardly when the machine is in use. The cover 101 has a front member 103 which is hinged at 104 to the-.loweredge of the front wall of said cover. This member 103 is adapted to form a closure for the front of the case when the machine is in a compact condition and is adapted to be moved out of the way with the cover 101. One or more clasps 105 ot any suitable form may-be provided to hold the cover 101 and member-103 in a closed position, there being a handle, not shown, if desired for carrying purposes.

It will be evident from theforegoing that the keyboard and keyboard frame with all of the parts mounted thereon may slide horizontally so as to move all of the keys within the main frame member to make the Inachine compact and to protect the Akeys against injury; that the keyboard member of the frame when forced rearward will move the carriage and its supporting bars forward as well as those parts mounted to move with the carriage; that the principle whereby con'ipactiiess is secured doos not prevent the proper operation of the various n'ieelmnisms by the keys, such as the escapement mechanism, the ribbon mechanism, and auch other parts as cooperate therewith; that the general form or construction of a standard Ytype-bar machine is n'iaintained when the machine is in its normal operative condition; that the compact principle is such that the. frame may be ol any suitable conclaim as new and desire to secure by Letters Patent 1.
