To au whom t 'mag/ 0011067171:

Be it known that I, CHARLES I )Hiiio .lt/loslaten, a citizen of the United States, and va resident of Groton, county of Tompkins, and State of New York, have invented certain neviT and useful Improvements in Type- Vriting Machines, of which the following is a full, clear, and exactdescription.'

This invention relates more particularly to the escapement mechanism of foldable Visible or front-strike typewriting machines in which the keys of the keyboard may be' brought into close relation to the platen to make the machine compact when not in use, and is a division of my application Serial No. 56,242, led October 16th, 1915.

One. of the principal objects of the invention is to provide a t-ypewriting machine in which a. universal or standard keyboard may be employed and in which the escapement mechanism for letter spacing the carriage may be operated by the keys of the keyboard and the entire keyboard and key action folded with respect to the platen to place the keys in compact relation to the platen without disturbing the coperative relation be'- tween the keys and the escapement mechanism.v v-

Another object of the invention is to provide a/.foldable support on which is mounted the type-bars and a universal-0r standard keyboard having individual keys for operat ing individual type and wherein the pivotal part of the foldable support may serveas a connecting means between the keys and the escapement mechanism for the platen carriage in order that. no break ordisconne-ction is necessary whether the machine is in a foldedposition or in an unfolded position.

A further objectpf the invention vto typewriter.

partly in elevation. Showing parts of the nia- 'is employed. it will be understood that the A still further object lof the invention is to provide a typewriting machine in which the escapement mechanism and the parts operating the same are of simple construction and may be readily' inade and assembled.'

With these and other objects' in view, the invention will be hereinafter more particularly described, with reference to the accompanying drawings, which form a pa't of this application, and will then be pointed out in the claims at the end of tlie description.

In vthe drawings, Figure 1 is a longitudinal section of one form of machine embodying the invention, showing a. construction wherein vthe entire mechanism of the machine may be inclosed within the carrying case which may form a frame or support. for the typewritermechanism.

Fig. 2 is a vertical sect-ion taken on the line II-II of Fig. 3.

Fig. 3 is a vertical transverse' sectiontaken on the -line .III-III of Fig, 1. the` type-bars and parts of the key action being removed. Y.

Fig. 4 is a vertical longitudinal section,

chine in, a ,folded compact condition.

Fig. 5 is alsectional plan view with parts of the'machine removed,.showing the meansf, whereby on the operation of the universal bar the escapement dogs may be operated; and y Fig.,6 is a fragmentary section of a part of the connecting mechanism between the foldable parts, showing how the escapement' mechanism may be operated withoutI anydisconnection Whatever'between the universal bar and the escapement mechanism.

'hile the invention is showny as applied to -a typewriter in whilch an inclosing case' folding principle betw en-jtli`efkey-operated levers and the escapeinent mechanism may' be embodied in-a machine in 'whi'c' nary or any preferred form of frame may be employed or a frame independent of suoli as the Constr c tion of thelescapement and operating means therefor may be employed case. and thatlsaid foldable principle as well 'in typewriters of various constructions.

The casing 10 has a main member 11 and 105 'a top member or cover l2 which 1s hinged rll i.

\ by springs supported by the segment.

at. lf3 to said maui member 1l. t the forward loweredge of the maininember ll is a foldable member l-L which is piioted or hinged at 15 to said main member l1 so arranged that in one position. the stays will act as alock and when forced againsty the springs 19 the case member 1l may be moved to its folded position.

A foldable support or member 2O ris plv-- Qtallv held to a transversel)v extendinfr rod which is supported in the sides or the main casingmem-ber ll and at itsI forward end said foldable support. Q0 ma)T be @oir nected by a'link QQ to the member l-.l so that themember or support 2O niav be folded with the member 1st of the case. The sup-1 port Q0 has sidesQS which mai7 be connected bva transverse bar 2st andmounted in said support 20 is a segment Q5. Type-bars Q6 are piroted to the segment in any suitable way. as to a rod 27, and said typebars are Aadapted to carryv a pluralitiY of tvpeand be supported at their outer end on a cushion Q8, the latter being held to a cushion supporting frame 294 'extending outwardlvY fromand rIhe type-bars are each normalliv forced' in one direction 30 and are each connected -bv a link 3l to one arm of abell-crank lever 32.

. Each bell-crank lever is pivotallv held to a rod or supportv 33. There are 'four rods each being adapted to support a pluralitv of the levers rl`he bell-crank levers each .have one arm. as 34C, provided with a cam edge. Sala vwhich is adapted to engage a cam edge 35 of key-operated levers- 36. rhese key-operated levers 36 are supported in groups or banks upon rods or supports 37 which are horirfontally` arranged in the nor. mal operative position of the machine under the rods and correspond in number to said rods 9 i. its each ke;Y is depressed the ram edge will operate'its coperatmg 'bell-crank lerer and thrtmgh a link 3l will more the type-bar upwardlyv aud rearward for printing purposes. and by reason of the arrangement in groups or banks a substantially uniform touch is obtained.

The. platen carriage usual or of an preferred form. As shown it comprises a rear `guide or base 39, they upper and lower edges of which are each prrr-sided with a racewa)` which 1s opposed to the raceway or track stantially instantaneously therewith.

may be of the of transversely el@ taeoeoa y tendingr bars or members i() and 41. both of which may be. secured to a strengthening plato or member Al. held to the rear plate or wall of the. main casingmember l1. Balls or other antidriotion devices e3 are ar ranged in the raceways to adaot the. bed and carriage to travel easily trai the machine. rlhe carriere maj la plates il' in which'is mounted to rotate. the

usual platen or roll The carriage may have the usual paper apron @and the usual linger knobs'li'for rotatingl the platen, and may' also be provided with the usual or any preferred form of line-spacing means, paper lingers and vother attachments usualljvT employed in t-ypev-:riting machines. but as such. features form no part. of the presentinred tion it is thought. unnecessartT to describe or show them in detail.

Any suitable .means may be providedas an escapemeutand letter-spacing means for the carriage 38'. it being),` necessari' however, that provision be made 'crlierebiv the folding principle involved will permit. the operation of such esca pementl during' the depressionof the keys for the printing operation, the letter-spacing morementtaking placev innue-4 diately after such printing operation or subs one eseapement meansr and operating mechanism therefor, l profid'e a universal bar -lS which is suspended by arnis if). the latter being pivotallT held at 50 on the type-,bar segment The 'universal bar i8 Ais adapted to be engaged by the rear cam edge 5l of the type-bars 2G. The purpose of the cam edge 5l of the type-bars is to start. theunirersal bar gradually during; the upward and rearward movement of the typef barsand ,toy give Athe universal bar an aceeli erated movement without "altering the uniform character of the touch ofthe keys and in order 'that no sudden ar on the keys ma)r be apparent to the operator when the tvpebars start. to actuate s AllA pair of upwardly fixed at their lower ends on extending rod 53 rotatably ends in the sides of the support :20. The free upper ends of the rods 52 rest idly against the rear surface of the universal bar ld Arms 5l project forwardl)v from the. rod 53 and said armshave their forward ends slotted t0 engage pins 55 carried by. the inner ends of armsy. The arins' are held to the transversely extendingpivotv rod 2l and serve, when the universal bar moves the arms 52, toy rotate the pivot'rod 2l., the latter being; rotatably held at its ends in the side members of the main casing ymember 1l.

The rod 21, Figs; 3 and 6, has a cam member 5f' secured thereto near one end thereof adjacent to the outer surfaceof one of the sides oi the support 20, and this cam inem- '57 has a substantially Vshap ed portion 59 fitting a lcorrespondingly shaped recess in f `theshidablc non-rotating cam member 58,

.the latter'being' slidably held by a key or lotherwise to a fixed sleeve through which one 'end of the rod Q1 passes, said cam memher 58 being normally forced inwardly by means of a 'springtljv The sliding cam member 58 is provided with'v an annular groove-Which is engaged by the forked .end tfof a lever 63. A The `lever tlis'substan- .y 'bell-crank shaped and is pivoted at to a lug on one of the sides of the case ber ligand has its uppervarm entend- D inwardly and providedwith 'a slotted or forked endI G6 which is adapted to engage a pin 6? extending outward from av rod 68,

so'that on each movement of the lever 63' .as

willvbe presently described,A the said rod 68 by means ofthe pin 67 will b'e rocked on its' pivot pins or screws located at thel ends thereof.'

On the rod. 68 are twodogs 69 and 70 the former'being the loose or limber dog andthe latterthejXed dog, and both -dogs being` adapted 4to rock back and forth with the.

partial rotary movement of the'` rod 68, The

.escapement dogs 6,9 and 7() are adapted toi engage the teethof'an escapementfwheel 71' the latter being'loosely mountedn a headed stud 72. A ratchet Wheel 73 latj the rear of the escapement wheel Z1/is engaged 4by thev tooth .of -a pawl .74 and movable with the .ratchet Wheel isa pinion .75.1 The pinion 7 '5 is in meshwith the teeth of a vcarriage rack 76, the said rack being secured to the -carriage bed 39.l The carriage has a flexible connection .'77 attached thereto which passes around a pulley 7 8 and then abolita spring drum 79.*by .which the carriage is kept unT der tension in the usual manner tending normallyto drive the Vcarriage across the machine in the usual way.

l'henthe keys 8O of the levers 36 are de- .c pressed to force the type-bars to printing position the cam 51 of each type-bar will move the universal bar and. this will rock the arms'Q. The arms 52 will rock the shaft or rod 53 and move the arms I54C and this will rock the arms 56 on the'pivot shaft :21 ot' the support Q0. This rocking movement of the rod or shaft Q1 will rock the cam member 57 and move the cam member 38 along said rod or shaft Q1 against the tension of the spring 6l' so as to move the lever 63 on its pivot Gat. This will rock the rofl 68 and will move the dogs therewith 'so that the tension of the spring in the drum T9 will by the usual action of the dogs permit the carriage to escapeand move a smvle space at cach depression. The pawl 74:

y will permit the carriage to bermoved back- Wardv in the usual way for starting anew escapementto permit the carriage to move across' the machine a single space at every .closing being completed when the cover line of writing withoutaffecting any of the parts of the escapenient mechanism-and i1n. mediately the carriage is released the tenlsion mechanism will again act through the depression of akey 80.

In addition' to the keys 80 forming a part of the-keyboard and for letter spacing without printinga space-bar 8l is provided. This space-bar '81 is held to arms or brackets 82 which 4are' pivoted at 83 to the ends of space arms or levers 84. The brackets 82 normally engagestops 85 sov that on' the depression of the bar 8.1 the space levers 84 will be operated by' the pivotal brackets 82. The space-bar may be folded upward and over-as shown in Fig. 4c to adapt the machine to b e made morecompact when in a folded {and'closed condition. The space leve-rs Si are'pivoted to one of the trans- 'ver'sely extended fulcrum rods 37 of the key-operated leversBG and at-their inner ends are bent downward 'so as to engagey under the pins 55, said levers being restored to their normal positionV b v means of oneor moresprings 86. As the space-bar isoperated vthe, levers 8a will be moved on their .pivots to forcethe inner ends upward and by their engagement under the pins 55 will .95 movev thel arms 56 as well asthe arms 54. and by moving the arms l5 will rotate ythev rod or shaft'Ql and through the cam mem bers 57 and 58 already described will oper'-l -ate the escapement mechanism for letter l.100

`within the lsidesof the main casing member 11 so that the" supporting casel member 1l may form a partial. closing of the case, said member 12 is moved from the. position shown in Fig. l to that shown 1n Fig. ha handle. not. shown, being provided at vthe,

4end of the case or other part thereof if 'desire-d for carrying'l purposes.

ItA vwill be evident further that all parts mounted'upon the foldablesupport Q0 partake of the folding movement of the'case member 14, so that notl only the type basket including the typey bars butl the entire keyaction partakes of such folding movement, and that all oftheseparts both vin the folded and unfolded positions remain in the same operative relation and withoutany -disconnection of any kind.

It will also beievident that simple means is provided wh'ereby'a'part of a typewriting machine may be foldable 'with respect to another partrto make themachine compact;

that simple'meansis provided whereby"the 7 keyboard and'those parts making theprint` escapement mechanism normally maintained ing mech'ani 'ninay be independently mountedf' with'respectto other parts with' isorganization ;whatever; that simple e ment mechanism is provided and that said escapement mechanism is adapted for typewriting machines whether employing an ordinary frame or wherein 4an inclesing case forms a supporting,- Jframe in. which latter event the ordinary independent' separate. carrying case usually employed may be dispensed with.

' llt' will be understood that any suitable ribbon mechanism may be-employed as well as other features, but as they form-no part of the present invention it was not thoughtnecessary `to either show or describe them herein. Y

Having thus described my "invention, ll

' claim as new and desire to secure by Letters in a fixed relation to thel platen carriage and adapted to permit said carriage to have let-- ter-spacing movement, and means operatively' connecting the universal bar to the escapem'ent mechanism to-adapt thel escapement mechanism to be operated each time a key-operated lever is Vdepressed and which permits the keys of the keyboard to be moved into close relation "to the platen carriage and the coperative relation. betweeny the univer-` sal bar and the escapement'mechanism maintained. l
