Specification of Letters Patent. Patented Sept,r 17, 1 918 Appli-cation filed March 6, 1916. Serial No. 82,404.

VTo all whom 'it may concern.'

Be it known that I, Pi-iiLirrE Dn CLAMEGY, a citizen of the United States, and a resident of Boston, county of Suffolk, and. State of Massachusetts, have invented certain new and useful Improvements in Type-Writing Machines, (Case F,)V of which the following a full, clear, and exact description.

This invention relates more particularly to the case shift mechanism of a' front strike or other visible typewriting machine which may bemade compact lwhen not in use to adapt the same for transportation and other purposes.

(.)ne of the principal objects of the invention isto provide a small compact portable typewriterl in which the keyboard,`including the shift keys, is mounted upon a frame part of the main frame and is slidably lheld to a main frame part, and is movable Jwith the shift keys `from a normal operativeor extended position to an abnormal. and more compactone when .not in use, and at the` same time, .if4 desired, so to constructhe frame that it may form an inclosing case for not only the typewriter mechanism but also the keyboard including the shift keys;

Another object of the invention is to` provide a writing machine wherein the platen carriage' may be given a shift movement, and said carriage given an additional abnormal movement to place the platen in an operative and more compact position with respect to the type. D

Other objectsof the invention arey to provide simple and` lefiicient shift mechanism whereby the platen ,and carriage may be moved from. a normal operative positlon for lower case writing to relatively different distances to adapt typesbars to have a plurality 'of type thereon; and to provide a case shift mechanism Whereinshift keys `may be moved v,relatively to other parts of the type` Writer from a normal o erative position to la more compact one'a-n theconnection betweenv thesliiftkeys and 'the parts operated Awfurther object offthe invention is to provideatypewriter in which the case shift mechanism includes a flexible and collapsi-- With these and other obiects inview, the

invention will be hereinaftermore particu section, partly in larlydescribgld- `vvith 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'longitudinal elevation, of one form of machine embodying the invention.

Fig. 2 1s a fragmentary sectional f taken on the line II-II of Fig. 1, showln means whereby the mounting for the shi t keys may be heldin a normal operative or in a compact. position.

Fig. 3, is a vertical section takenV on the line IIIIII of Fig. 1-

Fig. 7 is a vertical section of one side o1"4 machine taken on the-line VIIe-,VII of'Fig. 6; and i I.

Fig. 8 is an enlarged fragmentary verticall section Fig.

While' the invention is shown as applied to aparticular kind of typewriter in which lthe keyboard is mounted and connected to` the type-bars in a particular Way and the` different mechanisms are shown of a particular construction, it'vvill be understoodthut many 'of these parts maybe chan ed, and that some of the parts maybe lspensed with or others substituted therefor Without changing the naturev or character of the in,- vention.

' The inclosin support for thediiferentparts ofthe typewriter may be variously constructed. shown, the cas'e'or frame `10 comprises amain substantially box-like frame part 11, 100 Vhaving-abase 11, a rear Wall 12 a partiell Vopen r ont wall 12 and side walls 13. The base 11` may offset parts land 14, as shown inthe draw,-

at lTtothe taken ron the line VIII- Vlllof l g caselO or'other frame-orfV Y continuousor may have tvvo"i y member 18. This member 18 is hinged at thc forward edge of the top 1G, and is adapted to inclose the open front. or space 19 of the main part, member or section 11. At the t'ront portion of the main. trame part .is a keyboard memberor trame part. 20. This frame part 20 is slidably held to move horizontally within the main member 11 from a normal operative and extended posit-ion, as shown in Fig. l. to an abnormal compact one, as shown in Fig. The trame part of member 2() may hart` a substantially boxlike form ot' considerably less height and length than the main frame part 11. and said frame part has ay base 2l on which-may be supportinw Jeet 22. a front wall 23 having an exten( ed portion. as 2l. by which the frame part 21 may be moved inwardly and outwardly and a top portion or plate The base 2l of the trame part 20 is adapted to slide forwardly and rearwardly on the o ifset base part 1l and has its side walls 2 6 provided with slots 27. These slots 27 are each adapted to be engaged by the shank 28 of a pin or bolt 29, and engaging the threaded end ot' the shank 29 of each bolt is a thumb nut 30, `The shank of the bolt 28 has a square portio'nto fit the slot 27 and forms a bearing portion and guide for the sides of the frame' part 20during its horizontal sliding movement, Each bolt has an enlarged hen-d 31 so that by tightening the thumb nuts 30 at each side of the machine. the extensible and Vslidable frame part 20 may beheld either in its extended normal osition or in its compact abnormal position.

he front plate 18^0f theinclosing case is adapted to-rest against the upper surface of the top 25 of the frame part 20 when in a compact condition, and mounted upon the part 18 is a lock 32, as 'for example a lock such as is employed on desks and which is accessible by a key through an opening or keyhole 33 whereby 'the tumblers'of the loc-k may be disenga ed from or engage a slot 34 or other hol 111g mea-ns in the top 25 of the frame part 20 to locksaid frame part against access except by means of the key. The front `art 18. may be also provided with ahand e, as 35, for carrying purposes. -and at the 'rear portion the case may have end pieces, as 36, to adapt the platen carringe, as Will-be presently described, to have free movement transversely -of the machine when in use. The side or end pieces or members 36 are hinged to the rear wall 12 and are adapted to inclose the cutaway portions 37 of the side walls of the main frame part 11. The side pieces 36 have beaded or rabbeted'edges and the top member 16 may also be provided With a rabbeted or beaded edge so as to lock the end pieces or members 36 `in a closed position-When in the positioi.

Each bar (il is guided to board 38. The .keyboard may be of the usual standard or universal kind wherein a plurality ot' banks` or groups of keys are arranged each operating individual type, such banks being m three or more sets. according to the number of printing characters` and' whether or not a single case or double case shitt is employed. The keys 39 are each ari ranged upon a vertically movable stein 0r rod l0. laca stemt() is guided in a bushing or tubular part l1 extending upwardly from th:I top 25 ot the keyboard frame part 2 0, and at the lower end, ot' each. stem 40 is z yoke or head 42 to which is pivotally connected the arm 43 of a bcll-crank level' 4-1. The bell-crank lever l-l is-pivoted at 45 to a lug or bracket lt'textending inwardly from the frame part 2().said part 46 extending inwardly from the top 25 for two banks or rows of key-operated levers and from the front plate :23 ot' the frame part 20 for the third row ot'v key-operated levers. The keyoperated levers 4l have a pin-andeslot connection with the stems 40 and 3under each head 4-2 is a rubber or other strip fl to take the shock due to the return movement of the rods 40. The arms 48 of the key-0perated bell-crank levers are connected to springs 49, there being a spring t'or each lever and each spring being connected at one end to a other end to one ofsaid levers. A link or connection 50 extends from eachkcy-o`perated lever and has one end held to the short arm 51 of a level' 52. The links or connections 5() may be of wire, as piano wire, or of any other desired form` and is adapted when a key is depressed to force the upper arm 53 of one of the levers 52-inwardl v. The levers 52 are all mounted on a common pivot rod 5l which is curved according to the arrangement of the levers 53 and the parts actua-ted thereby. The arms 53 of each lever 52 is link 56 being pivoted at 57 to a lug 58 of a type block or head 5 9. Each-type block has a plurality of characters or type 60 thereon, in this case three characters be? cause there is double case shift` :is will be presently described. one of said characters representing the lower case type, another character thenpper case type, and the third lclnlra'cter or type, gures, punctuation marks` etc.. this arrangement beingr varied according to the construction of the machine. The type hea-ds or blocks 59 are held-to bars (il. slide in a bearing 62 and is normally foreedin one direction by a spring G3. one end of which is held to the forward end of said bar and the other end to a part Zot the main casingu orkframe. The. bars` G1 are held. in slots and over the bars is a finishing aud a retaining' plate Gli The bars (i1 are arranged in av cu'rved path so that as they are propelled 'or forced inpart ot' the frame part 2O and atitsv pivoted at to a link 56, said lll-0 lfi -the letter-feed movement of the carriage,

lt are pivoted to links or connecting' rods fit) and these links 99 are pi voted at their miler ends to arms 100, The arms 100 are held to studs 101 and on said studs 101 are eccentrics 102 so that as the linksvlll arel .t'orced inward the arms or cranks 100 will rotate the eecentrics 102. In the compact. position ot' the parts as shown in Fig. 0. thfeprintingv point ot' the platen is below the plane. of travel of the lower case type on the type heads or blocks. lVhen the keyboard frame partI 20 is moved outwardly to a normal operative. position. the. transverse bar 92 by reason of its connection with the links 93 will 'loree the. arms 95 downwardly from the position shown in Figi to that shown in Fig. 1. rlhis downward movement of the arms` J0 will torce the linksl 9!) forwardly and such forward movement of said links` llfl will rotate the eccentrics and. this will elevate the carriage and platen to its normal operative position wherein the printingpoint ot the platen is in a direelV line with the travel or movement of the lower type eharaeter otthe typebars. In this position the platen may be shifted tor the ilitlerenty type characters as already deseribed. and may be restored to its normal position on the release of the shift keys either by gravity or by spring' orv springs.y not shown. tor that purpose. During; the compact movement when the keyboard trame 20 is moved inwardly wit-hin the ease such movement `will elevate the' bar 92 by reason ot the link connection 9?), and thisvvill raise the arms 96 and force, the links or arms Sl!) inwardly thereby rotating the ect-.entries 102 which will permit an abnormal movement ot' the carriage and platen allowing the same to drop below the path ot the type to an inoperative position. During this compact. movemtaitv the `wire. link connections are raised by the bai- 92 and are maintained in their proper relation by reason of said bar 9:2- and without liability of becomingv entangled. A vconnection is thus always maintained between the ltey-olierated llevers and the type-bars as -well'as between the shift keys and the parts operated thereby, and during the extended and compact movement ot' the keyboard the normal and abnormal position ot' the platen and carriage is automatically effected through the action of the eceentries 102 and the connection between said eeeentries and the keyboard frame scribed.-

In the drawings I have illustrated a form ot escapement mechanism for controlling part 20 as already deribbon mechanism. and other features of a complete typcwriting' machine; but these features. form no part of the present invention,and for tha-treason it. was thought unnecessary to describe the same in detail as they form parts of separate applications tiled by nieMarch (l, 1910`r Serial No. 82,40?) and Serial No. 82,406.
