- use to adapt the'same for transportation and a citizen of the United Sta Be-it known that I, PHILIPPE on Gunner, and a rest dent of Boston, county of Sufio k, and State oiMassachusetts, have invente'd'certam new and useful Improvements in Type-WritinF Machines, of which the following'is a ful clear, and exact description.
This invention relates more particularly to the esca t mechanism .ofE a front strike or ot ei-Srisible typewriting machine which may be made compact when not in other purposes.
One of the principal objects of the invention is to provide a small compact portable typewriter in which the keyboard is mounted u n a frame part or member which is slid'aheld to the main frame part or member ofthe machine and is movable from a normal operative or extended position to an abnormal and more compact one when not in use, and at the same time so construct the frame or support that it ma form an inelosing and protecting case .or the escapement mechanism and, the keyboard when-in a compact position, and whiclrmay be opened to adapt the typewriter keys and other parts tobereadily accessible for oper ation in the usual way.
Another object of the invention is to provide atypewriter which .is very compact when not in use and which is so constructed that it may be readily transported as a part of a rsons luggage, or for other purposes.
Qt er objects of the invention areto provide a typewriter in which the support may i be variousl constructed whether asavcase inf-Which al the mechanism is mounted in order that a separate carryin case may'be dispensed with, or wherein .t 1e framemay beconstructedsinmly as a mounting" for the dili'e rent mechanisms so that-the typewriter l may be placed in a separate and; independent case, if desired; to, provide a simple and efiective mechanismto control the feed of the carriage; to provide a writing machine wherein the platen carriage and part of the escapement mechanism may be given different shift movement-sic! different type carried' by the different type-barsfwithout separating the escapement' parts; and to pro vide means whereby an a normal movement of the platen. carriage to an inoperative Specification or Lettctl Patent.

position may be automatically eflected when the keyboard is moved from its normal operative position to a compact position, and during such abnormal movement of the platen carriage have the parts of the escapement mechanism maintained in operative relation. U
' A further ob ect of the invention is to provide -means whereby the inclosing case of.
the mechanism may be. logked and the. parts so constructed that the .eseapement mechanism is entirely protected and inaccessible when not in use.
A still further object-of the invention is to provide a typewriter wherein the-platen carriage and the keyboard may have a relative movement from a normal operative position to a more compact one or vice versa, and duringsuch movements have the connection between the keys and themeans controlling the escapement mechanism maintained without any disconnection or disorganization.
With these and other objects in view, the invention will be hereinafter more particularly described with referenceto the accom- 'panying, drawings,which form a part of this application, and will then be intedoutin the claims at the end of the escrip- In the drawings, Fi ure ;1 is a longitudinal section, partlyin ovation, of one form of machine embodying the invention, showing the escapement mechanism in position for operation when one of the keys is de-. pressed.

Fig. 8 is a vertical section, partly in elcvation, of one side of the machine, said section being taken on the line VI-II VIII of The inclosingvcase 10 or other frame or.
' support for the different parts of the typewriter may be variously constructed As shown, the case or frame 10 comprises a main substantially box-like frame part 11,
havin a base 11, a rear wall 12, a partially open ront wall 12*, and side walls 13. The base 11 may be continuous or may have two offset parts 13 and 14, as shown in the drawings, said oflset parts being provlded with the usual supporting rubber feet 15, if (lcsirecll A top or cover member 16, is hinged at\17- to the upper part of the rear wall 19., and at the end opposite the hinge 17 oisaid cover member or top 16'is a front plate or member 18. This member 18 is hinged at the forward edge of the top 16, and is adapted to inclose the open front or space19 of the main part, member or section 11. At the front'portion of the main frame part is'a keyboard member or frame part 20. This frame part 20 is slidably held to move horiz-zmtally within the main member 11 from a normal operative and extended posi- .ion, as shown in Fig. 1, to an abnormal compact one, as shown'in Fig. 4. The frame part or member 20 may have a substantially box-like form of considerable less height and length than the main frame part 11,
and said frame part 20 has a base 21 on which may be supportin wall 23 having an exten ed portion, as 24, by which the frame part 21- may be moved inwardly and outwardly and a top portion or plate '25. The base 21 of the frame part 20 is adapted to slide forwardly and rear wardly on the offset base art 14 and has its side Walls 26 provide These slots 27 are each adapted to be engaged by the shank 28 of a pin or bolt 29, and engagin the threaded end of the shank 29 of each bo t is a thumb nut 30. The shank of thu. bolt 28 base square portion to fit the slot 27 and forms a bearing portion and guide forthe sides of the frame part 20 -.durin its horizontal sliding movement. Each bolthas an enlarged head 31 so that by tightening the thumb nuts 30 at each side feet 22, a front with slots 27.
of the machine the extensible and slidable frame part 20 may be held either in its extended normal position or in its compact abnormal positi0n. The front plate 18of the inclosmg case is adapted to rest a ainst the upper surface of the top 25 of the rame part 20 when in a compact condltion, 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 thelock may be disenga ed from or made to engage a slot 34 or ot er holding means in the top 25 of'the framepart 20 to lock said frame art a ainst access except b means of the ey. he front part 18 may portion the case may have end pieces, as 36, to adapt the laten carriage, as will be presently descri d, to have free movement transversely of the machine when in use. The sideor 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 Biecesor members 36 m a closed position w en in the position shown in Fig. 4.
also provided with a handle, as.35, forcarryingpurposes, and at the rear On the frame part 20 is mounted the keyboard 38. The keyboard lnay be ofthe usual standard or universal kind. wherein a plurality of banks or groups of keys are arran (1, each operating individual type, such ban s being in three or more sets, according:
to the number ofprinting characters, and
guided in a bushing yoke or head 42 to which is pivotally connee-ted the arm 43 ofa bell-crank lever 44. The bell-crank lever 44 is pivoted .at 45 to a lug or bracket 46 extending inwardly from the frame part 20, said part 46 extending in-, wardly from the top 25 for two banks or rows of key-operated levers and from the front plate 23 of the frame part 20 for the third row of key-operated levers. The keyoperated levers 44 have a pin-and-slot connection with the stems 40'and under each head 42 is a rubber or other strip 47 to take the shock due-tothe return movement of the rods 40. The arms 48 of the key-operated to a1ink56, said link 56 being 1 type b sired form, and is adapted when a key is depressed to force theupper arin 53 of one of the leverg52 inwardly. The devers' 52 are all'x mounted. on a common pivot-rod 54 which is curved according to the arrangement of the levers 53 and the parts actuated thereby.
The arm 53 of each lever 52 is pivoted at'55 pivoted at 57 to a In 58 of a type block or ead 59. Each lock has a plurality of charactersor type 60 thereon, in this case three characters because theme is double case shift, one, of said characters representing the lower' case type,
another character the upper case type, and the third character or type, figures, punctu'ation marks, etc, this arrangement being varied according to the construction of the machine. The t ope heads or blocks 59 are held 1 to bars 61. ach bar 61 is guided to slide in 1 a bearing 62 and is normally forced in one y direction by a spring 63, one end of which v the wor I 61? are thus substantlally radially arranged is held to the forward end of said bar and the other end to a part of the main casing or frame. The bars 61 are held in slots and overthe bars is a finishing and a retaining plate 64. The bars61 are arranged in a curved path'so that as they are propelled or "forced-inwardly they will move toward the prlntin goint to impress a character upon eld upon the platen 65. 'The bars with respect tothe pnilttingpoint so that all the ty e of all the'bars as each one .is forced inwardly through theij pvement of the levers52, links 56 and bars 61 on the depression of the keys 39 will strike at the same point on the work sheet. This arran ement of the type-bars is not broadly new. nstead ofthe type-bars having a horizontal slidin movement they may have an. upward an rearward movement as is common in most standard visible writing machines.
The banks or groups of keys 39 and the bell-crank levers 44 all move bodily with theframe'part toward or away from the boardas a unit to be movedinto the main t e-bars and the platen carria e 65 and, uringsuch movement said ban s of keys,
and levers maintain a fixed relationwith respect to each. other, thus 'adaptlng the keyframe member to make the machine compact or to bemoved to an. extended operative position at'the will of the operator. r The p aten 65 is'rotatably mounted upon endpieces or brackets 66 61? a carriage 67. The plateh carriage 67 has a base 68 which is constructed'to move transversely of the ma chine and may be guidedin grooves in a car- H'age bed- 69. The carriage bed 69 is held to move vertically at its ends for case shift as 'will be presently described.- The platen carriage may have the usual parts mounted usual construction and has its shaft 75 .These lovers 83 and thereon which coiiperate with the platen, such as line-spacing, ribbon vibratin mechanism and other features usually emp oyed in connection with typewriting machines. Some of the parts which are common to the ordinary typewriter are not shown and some features are shown in part and others simply sufigested. There may be one or more feedro only yne beingl shown,'as roll 70', and adapted, toguide' t e paper or work-sheet about the platen is a paper apron 71. Paper fingers 72 are held upon a transversely ex-' tending rod 73 which may be graduated or not, as desired, and these aper fingers are adapted to be held in various positions. by means of thumb-screws 74 so that dillerent .widths' of about the p aten 65. The platen may be o rojecting beyond the end bracket 66, an 'on each end of said shaft may be a knob 76 by constructions may be employed. As'shown,
aper may be properlygmlider:
the platen carriage is given a vertical movement Tor .upper case printing, and in this particular machine the platen carriage has two shift movements to. adapt the type heads each to have three characters thereon. The
normal operative position of the platen with respect to the type on the blocks 59 i such that the rinting point is directly inline.
' with the ower type character on each type block, the normal position of the platen'and carriage being obtained by mechanism presently to be described. The carriage bed'69 isjheld to vertically movable partsor slides 77 These slides 77 have a dovetail connec U011; 79 locate frame. part 11, so that the carria e and laten may be moved vertically an uni ormly ,iguided at both ends during such vertical movement. A pin 80 extends inwardly from .each part 77 of the :platen carriage and adapted to engage said pins are arms 81 and 82. The arms 81 and 82 are arranged in sets, there being an armlof each set located '105 as 78 with the enlarged parts or guides on opposite sides of the main at opposite sides of the machine toimpart unifprm vertical movement to the platen carriage. The arms 81 and 82 'are slotted to permit relative movement between the. arms 81 and 82 and the carriage for the different arms Blare connected to bollcran \"ers 83 and the arms 82 to bell-crank the boll-crank leverson opposite sides of the machine may be moved in pairs, said rods 85 and86 having hear ngs in lugs 86 on the '120 shift movements of the platen carri e. The I frame base part 13. The arms 87 oflhe bell-crank levers 83 and thearms 88 of the bell-crank levers 84' are of such lengths, that the same movement of said arms are adapted to impart different shift movementsto the platen carriage according to the spaclng between the type on the blocks or heads 59.
The bell-crank levers 83 and 84 are each connected by a wire link 89 and these wire links are connected to key-operated bell-crank levers in the same Way as the links 50 are connected to the bell-crank'levers 48. Two
shift keys 90 and 91, Fig. 7 are located on one side of the machine, and these keys when depressed will operate the bell-crank levers 83 and 84 to impart different shift movements to the platen carriage as already described.
The links 50 and 89 are guided in a transversely extending bar 92, there being an ap erture in 'said bar for each link so that the links are properly held spaced apart. The bar 92 is held to one end of links 93 and these links at their other ends are pivotally held at 94 to the sides of the frame part 20. The ends of the bar' 92 are guided in slots 95 of arms 96. These arms 96 are located on 0p,- posite sides of the machine and are'pivotally held at 97 to lu s 98 extending upvwardly from part 14 o the mainframe part 11. The upper ends of the arms 96 are pivoted to links or connectin rods 99 and these links 99 are pivoted at t eir inner ends to arms 100. The arms' 100 are held to studs 101,v Fig. 8, and on said studs 101 are eccentri cs 102 so that as the links 99 are forced inward the arms or cranks 100 will rotate the eccentrics 102; In the compact position of the parts as shown in Fig: 4, the'printing point of the platen is below the plane of travel of the lower case type on the type heads or blocks. When the keyboard frame part 20 is moved outwardly to a normal operative position, the transverse bar 92 by reason of its connection with the links 93 will force the arms 95 downwardly from the position shown in Fig. 4'to that shown in Fig. '1. .This downward movement of the arms 96 will force the links 99 forwardly and such forward movement of said links 99 will rotate the eccentrics and this will elevate the carriage and platen to its normal'operative position wherein the printing point of the platen is in a direct line with the travel or movement ofthe lower type character of the type-bars." In this position the platen may be shifted for the different type characters as already described, and; may be restored to its normal position on the release of the shift keys either by gravity or 'by spring or springs, not shown, for that purpose. During the compact movement when the key-' board frame 20 is moved inwardly within the case such movement will elevate the bar 92 by. reason of the-link connections 93, and
this will raise the arins' 96 and force the links Or arms 99 inwardly thereby rotating the eccentrics 102 which will permit an abnormal moveme nt, of the carria e and platen allowing the same to drop be ow the path of the type to an inoperative position. During this compact movement the wire link connections are raised by the bar 92 and are maintained in their proper relation by reason of said bar 92 and without liability of A connection is thus becoming entangled. always maintained between the key-operated levers and the the shift keys and the parts operated thereby, and during the extended and compact movement of the keyboard the normal and abnormalposition of the platen and carriage is automatically effected through the action of the eccentrics 102 and the connection between saideccentrics and the keyboard frame part 20 as already described.
type-bars as well as between A special construction of escapement mechanism is employed for controlling the letter-feed movement oi the platen carriage. Each type ba'r operating iever52 is provided with a projecting part 1035and this projecting part overlies a universal bar 104. The
"of the rear-wall 12 of the main frame part un1versal bar is. curved to conform to the arrangement of the type-bars, and said uni 11 or otherwise, and interposed between said wall and a collar 111 on each rod'110 is a spring 112 tending normally to force each rod 110 forwardly to move-the universal bar against-the levers 52. Therods 110 are I connected together by a' rod 112 and mounted to move with sa id --;rod is any upright arm 113. This arm 113 is formed in. two
parts 114 and 115. The part 115 is pivoted at 116 :9 th; part,114-to move therewith, there being a shoulder 117 to prevent movement of the part relative to the part 114 I except inone' direction, a spring 118 being provided to hold the two parts of the arm 113 normally in a'linemen't. The part 115 'is adapted to engage an arm or projecting part 119 on a pivoted escapement dog or detent-120Q The'detent 120 has dogs 121 and 122 and is adapted to engage the teeth of'a rack 123 extending downwardly from'the platen carriage base 68. pivotally held to a fixed rod 124 and the The-detent 120 is I rack 123 is of the bar-like form and of such a 'width that .the platen carriage may be moved relatively-to the escapement dogs in a vertical direction without disengagement-,1
of the dogs-and rack during the shift movement of the platen carriage. .The dogs 121 and 122 are adapted to engage'the teeth of as rack ma its moveinput in the orin a'n preferred way, samd can'iage' being under e tensionof the springer-ranged in a drum 125, there v :a flexible connection between said.
part. of the carriage tending transversely e escapement amen normally to forcethe' carria .of the machinefas usual.
' dogs, theremay be a limber and a fixed 1,0 dog if preferred, are not actuated during.
, the rearward movement of the universal bar, the part115 of the arm 113 yielding during said rearward movement to pass by the am 119, but on the return movement '0 15, the universal bar the part,115 will actuate,
the escapement dogs to permit-the tension mechanism to force the carriage the distance of a letter-space, said part 115 again passing to the front ofthe-arm 119. The purpose of he 7 the escapement dogs operated during t a return movement of the universal bar is to avoid the feed movement of the carriage takin place'at or-about the time the tyfis is m 'ng its impression on the worka ut the platen. The universal bar is as herein stated held to move with the arms 106, and b havin said arms located on o posite si es of t e longitudinal center of te machine a uniform movement so, is given to the universal bar no matter which lever 52 'is operated, the rod 112' which com nects the rods 110 being bent substantially centrally thereof, as at 126, so as not to mt'erfere with the verticalrod 124 on which 86 the escapement detent 120 carrying is mounted. p
The escapement dogs are adapted to be operated bya' s ace bar 128 to letter spacei .pivoted to, a bracket on the frame'base part14, an d is normally forcedin one d1- rection by a sprin 131. The upper endo the-arm 181 1s a agted' to engage a down wardly extending ar orpart 132.. This part 132 is held to the universal bar and 65. when the space bar is depressed so as to move the lever 130, the part 132 will be up erated and will force the universal bar rearwardl and o crate the escapement dogsas valrea ydescri 5'0 The construction and operation ofthe invention will be readily understood from the fore oing description when taken in connection with the accompanying drawings.
Assuming the parts to be in the position esfshown in Fig. 1, it will be apparent that 'riage bed to s their rearward movement forcing the type to make an impression upon the work about "the platen. On the, release of the keys there typebars andparts-will be restored to their normal operative position. As each lever 53 is operated the universal bar 104 will f be, moved and by means ofthe vertical arm 113 the escapement dogs will be operated during the return movement of said arm, thus permitting the carriage to move a let! ter space under the tension of the drum- -125. The platen carriage may be shifted 'ior capitals and figures as already described.
When the machine is to.bemade compact the platen carriage is moved alon the carthe knobs within the side-walls 13 of the main frame part and the keyboard frame art 20 is moved inwardly as shown in ig. 4. This inward movement off'the keyboard frame part will force the transversely extending bar 92 upwardly and will cause the rods or links 99 to, rotate the eccentrics'102, thus permitting the platen and carriage to lower to an inoperative I osition with respect to; the type. The en s 36 .of the casing or frame may be moved to close theopen space 37 in the side walls 13, and the top or cover 16 and front plate or member 18. may be moved to the sition shown in Fig. 4, In this position t e front plate and cover may be held by 'means ofthe lock 32, a which. time the mac ine is in condition for transportation, an .the parts concealed and protected. a
While one form of ribbon mechanism is, shown, such mechanism forms no pm of thepresent invention but is claimedin a separate application. l a
