To @ZZ whom t may concer/n:

Bc it known that l, PHILIPPE DE CLAivIEoY, a citizen of the United States, and resident of Boston, county of Suffolk, and State ofl ,the printing instrumentalities.

Anotherobject of the invention is to p rovide a visible typewriting machinehaving upwardly and rearwardly movable type- 'bars, a universal keyboard sl-idable rearwardly beneath the type-bars, and collapsi* ble means forming constantly maintained mechanical operating connections between the keys and the devices operated thereby.

A iurther important object of the invention is to provide a typewriting `machine having a platen carriage andvertically'ex tensible and collapsible means mounted on the carriage Jfor supporting the platen, whereby the platen may be moved Jfrom a normal elevated position above the carriage downwardly to a lower and more compact position above the carriage` and out `ot cooperative relation with the type-bars. y

A further important object oftheinvention is to provide a visible typewriting machine havinga ribbon holder and platen and collapsible devices for supportingr the platen and ribbon holder.

Another object o the invention is to provide a typewriting machine in whichthe platen carriage is providedwith collapsible platen supporting means and the carriage bed is provided with collapsible means for holding the ribbon in cooperative relation with the platen.

A further object of the invention is to provide a collapsible visible typewriting machine having upwardly and rearwardly swinging type-bars supported on one frame part, a keyboard frame part slidable `from an extended position to a more compact position beneath the type-bars, a plurality of banks of keys mounted on vertically slidable stems supported on the keyboard Jframe part fixed distances apart, and collapsible oscillatory means constantly connected with the key stems and type-bars and adapted, when oscillated by depressing the keys, to actuate the type-bars.

Another object of the invention is to provide a light and inexpensive collapsible typewriting machine in which the mechanisrn is supported on a box-like frame adapted to completely inclose the mechanism when the machine is collapsed, said box-like frame having hinged sections adapted when opened to permit the parts of the machine to Y be extended into coperative relation.

A further object is to provide a collapsible typewriting machine having a box-like mainv chine collapsed Fig. 3 a plan view of the machine in extended conditlon;

Fig. 4. a vertical sectional view taken ceni trally or" the machine with the vparts in the positions shown in Figs. l and 3;

Fig. 7 a front elevation or' the machine in extended condition; Y

Fig. S a detail view showing a part of the key action; andV Fig. 9 a detail 'view showing part of the platen shift mechanism.

Referring to the drawings by numerals, the trame of the machine comprises a boxlike inclosing casing having a rigid main portion formed with a bottom'l, a rear wall 2, and side walls 3. A plate or casing section 4 is hinged at 5 to each of the side walls 3, and a front wall section 6 is hinged at 7 to the forward edge of the bottom 1 of the main portion of the combined casing and frame. A cover or upper portion of the casing is hinged at 9 to the upper edge of the rear wall 2 and is preferably formed of a plurality of

hinged sections

10, 11, 12 and 13. The hinged front wall section 6 is provided with a pair of rubber feet 14 adjacent its forward edge and the bot-tom 1 of the rigid main section of the frame is provided with a rubber foot 15 adjacent each corner thereof. rl`he upper edges of the'side walls 3 of the main section of the frame are connected by a transversely extending plate 16 which is depressed intermediate its ends at 17 to receive the type basket, and said walls 3 are also connected by a finishing plate 18 which extends between said walls at the front edges thereof.

A keyboard frame part 19, preferably formed with integral top, bottom, side, and front walls, and having an open rear end. is slidably held to the main frame part to move forwardly and rearwardly out of and ,into said main frame part. The keyboard frame partV 19 is supported on the hinged front section 6 of the inclosing case or main frime when in its normal extended position. and is held to the main frame part by ribs 2( formed on the sides of the keyboard frame part and slidably engaging in grooves 21 formed on the inner surfaces of the side walls 3 of the main frame part. The extent of the sliding movement of the keyboard frame 19 is limited by thumb-screws 22 extending through apertures in the side walls 3 of the main frame and through elongated slots 23 in the side walls of the keyboard frame. By loosening the screws 22 the keyboard frame may be moved into or out of the main frame, and may be locked in its adjusted position by tightening said screws.

A plurality of rows or banks of keys, forming a universal or standard keyboard. are mounted on the keyboard frame part 19 to move therewith7 and the banks of keys are held spaced a fixed distance apart at all times. Each type-bar operating key 24 is rigidly held on the upper end of a vertically reciprocable key stem or rod 25 extending through the top wall of the keyboard frame 19 and slidably guided in a tube or .sleeve 26 rigidly held at its lower end to said top wall of the keyboard frame. Each of the stems 25 and sleeves 26 supporting a bank of keys are of the same length, but the stems and sleeves of the several banks are of different lengths to support the rows or banks of keys in different horizontal planes. The extent of depression of the keys is limited by the engagement of the keys with the upper ends of the sleeves 26. and the upward movement of the keys is limited by collars 27 formed on the stems 25 and normally engaging the under side of the top wall of the keyboard frame 19.

Each Vof the stems 25 is operatively connected to rotate a jointed and collapsible rock shaft 28, there being a shaft 28 for each key stem 25. Any suitable operating connections between t-he stems 25 and shafts 28 may be provided. As shown, each stem 25 is provided with a horizontally extendingl arm or projection 29 working in an elongated slot 30 in the outer end of a rock arm 31 fixed on the forward end of the rock shaft 28. Each shaft 28 is formed with a forward section journaled in a bearing formed in a post 32 held to the bottom of the keyboard frame 19, and is also journaled in one of aseries of apertures in an upstanding rib or flange 33 formed on the bottom of the keyboard frame. Eachv shaft 28 is formed with an intermediate section 34 extending through one of a series of apertures or bearings formed in an upstanding rib 35 carried by a slide 36, and a rear section 37 extending through and j ournaled in one of a series of apertures or bearings in an upstanding rib 38 rigidly held to the bottoni 1 of the main frame part. The slide 36 extends transversely of the machine and the ends thereof slidably engage in the lower groovesy 21 formed in the side walls 3 of the main frame. The intermediate section 34 of each shaft 28 is shift-able forwardly and rearwardly with the slide 36 and is connected with the front section of the shaft by a knuckle jointed shaft section 39. The knuckle jointed shaft section 39 is pivotally connected at its forward end with the rear end of the forward shaft section by a horizontal pivot pin 40 and is similarly connected at'its rear end by a horizontal pivot pin 41 with the forward end of the intermediate longitudinally shiftable shaft section The rear end of shaft section 34 is connect-ed with the forward end of the shaft section 3T by a knuckle jointed shaft section 42 similar 'to the jointed section 39. The section 42 is held to the

sections

34 and 37 by horizontal pivot pins 43 and 44, and the knuckle joints 45' and 46 of the

shaft sections

39 and 42 are preferably constructed as shown so that the pivotal points thereof are held out of alinement with the shaft bearings. As a further means for preventing the knuckle oints from being shifted into alinernent with the shaft bearings when the shaft is extended. the parts of the shaft are formed of such length that the screws 22 will engage. the rear end of slots 23 in the keyboard frame 19 and stop the outward movement of said frame before the shaft 28 has been extended sufficiently to bring the pivotal points of the knuckle joints in alinement with the shaft.

A drum 47 is fixed on each ofthe rear sections 37 of shafts 28 to rotate therewith when its associated printing key 2li is depressed. Flexible wires or cords i-8 are secured at their lower ends to the drums 47 to wind thereon, and the upper ends of said cords are secured to rearwardly extending arms or projections 49 formed on the type bars 50. Each type bar 50 is pivotally mounted adjacent its rear end on a curved rod or type-bar-hanger 51, rigidly held at its ends to the transversely extending frame plate 16 at opposite sides of the depressed portion 17 of said plate. The segmental basket of type bars is normally supported in a horizontal position within the depression 17 formed in the plate 16, f

the heads of the type bars'O being normally supported on a curved type bar rest 52. Suitable springs 53 may be provided for normally forcing the type bars rea-rwardly and downwardly, and suitable springs 54 are provided for normally holding the rock arms 31 and keyrstems 25 in raised position. It will be obvious that, upon the depression of one of the printing keys 24, its coperating jointed shaft 28 and drum i7 will be rotated, winding cord 48 on said drum, and causing the associated type bar to swing upwardly and rearwardly to the printing point.

A platen carriage 55 is supported adjacent the rear end of the main frame part above and at the rear of the type bars 50, and is adapted to travel transversely of said frame part on a carriage bed 56. rl'he carriage bed 56 is fixed adjacent its'ends to the upper ends of a pair of vertical slides 57 of dovetail form, slidably held in vertically extending undercut grooves or ways 58 formed in the side walls 3 of the main frame part. The lower ends of the slides 57 normally rest at the lower ends of the ways 58, as shown in Figs. 4i and 5, to support the carriage bed in its normal position. i

rljhe carriage 55 is provided at each "end thereof with means for rotatably supporting a platen 59. As shown, the carriage and bed are normally supported in `close proximity to the type bar hanger 51, and means is provided for normally supporting the platen in an elevated position above the carriage in coperative relation with the type, said platen-supporting means being collapsible to permit the platen to be lowered into close proximity with the `carriage and out of coperative relation with the type to reduce the height of the machine when' not in use. I prefer to employ for this purpose the vertically collapsible supportingmechanism shown in the drawings.

The collapsible supports at each end of Vthe carriage are constructed in the same manner and each comprises a pair of knuckle jointed

arms

60 and 61 in the upper 60 is provided witha forwardly breaking,

knuckle joint 67, and arm 61 is provided with a rearwardly breaking knuckle joint 68.V The sections of the arms 60 and 61are normally held in alinement by a pair of

links

69 and 70, pivotally held at their lower ends on the shank of a locking screw 71 working in a vertical slot 72 in an upstanding plate or bracket 7 3 which is rigidly held to the end ofthe carriage The upper end of link 69 is pivotally heldfto thepivot pin of the knuckle joint 67 of arm 60, and the upper end of link 70 is pivotallyrheld to the pivot pin of the form saper guiding and yfeeding meansr may be'provided. I have shown a feed roll 77 rotatably supported at its ends in the lower ends of Va pair of arms 78 iiXed at their upper ends on square bosses 79 formed on the upper ends of arms 61.. The usual thumb wheels 80 may be provided for rotating the platen. H

The ribbon 81 is wound in the usual manner ontwo spools V.82 mounted on shaftsf83 supported on the transversely extending frame plate 16. Any suitable mechanism may be employed for rotating the spools 82 to feed the ribbon lengthwise, and any desired means may be provided for vibrating the ribbon to cover and uncover the printing point. cent the printing point by a vertically collapsible ribbon holder having a ribbon guide 84 of substantially U-shape, the upwardly extending arms of which are forked to receive the ribbon and permit lengthwise and vertical movement of the ribbon'relatively to the holder. The U-shaped portion 84- of the ribbon holder is mounted on a collapsible support constructed in substantially the same manner as the collapsible platen supporting means heretofore described. This collapsible support comprises a plate or rlfhe ribbon isV supported adja-V versely extending' member of the U-shaped' ribbon guide 84, and are held to the plate 85 at their lower ends by pivot pins 92 and 93, respectively. A pair of links 911 and 95 are pivotally held at their lower ends on the shank of the locking screw The upper end of link 94 is pivotally held to the pivot pin of the outwardly breakingknuckle joint 96 of arm 259, and the upper end of link 95 is pivotally held to the pivot pin of the outwardly breaking knucke oint 97 of arm 90. Arm 90 is provided at its upper end with a stop or lug 98 and arm 89 is provided with a similar stop 99, said stops being adapted to engage under the ribbon guide S-f at opposite sides of the pivot pin 91 when the ribbon holder is extended to prevent rocking of the guide portion 84 of the ribbon holder.

The head of each of the type bars 50 is preferably provided with three type, as shown, and means is provided for imparting a double case shift movement to the platen. The middle case shift keys 100, one of which is provided at each side of the keyboard, are supported. on vertically reciprocable key stems 101 similar to the key stems 25, and operatively connected to r :ate the jointed and collapsible rock shafts 102 through rock arms 103. The rock arms 103 and rock shafts 102 are constructed and mounted in the same manner as the'typebaroperating shafts 2c. .Rock arms 129 are held to the rear ends of the shafts 102 and the outer ends of said rock arms are pivotally connected at 1041 with the lower ends of links 105, the upper ends of which are forked as shown at 1.06. The upper case shift keys 107 located at each side of the keyboard are mounted on reciprocable key.

stems 1.08 connected. with rock arms 109 to rotate the jointed and collapsible rock shafts 110. Rock arms 111 are held to the rear ends of the shafts 110 and are pivotally connected at 112 with the lower ends of links 113 the upper ends of which are forked as shown at 114. The slides 57 upon which the carriage bed 56 is supported, are connected at their lower ends by atransversely extending` rod 115 which extends through the forked upper ends 10G and 114 of the

links

105 and 113. The rod 115 is formed with angular enlarged portions 115 extending through the forked ends 10G and 114 of the

links

105 and 113, and pins 125 and 126 extend through said angular portions and engage in

slots

127 and 128 formed in the forked ends of said links and serve to normally hold the links in the position shown in Figs. 4.-, 5 and 9. The rock arm 1.11 is longer than the rock arm 129 to adapt a greater vertical movement to be imparted to the platen by the shift keys 107 than that imparted to the platen by the shift keys 100.

r1`he space bar 116 is supported on vertically reciprocable stems 117 passing through tubular sleeves or guides 118 held to the keyboard frame part 19. Each stem 117 is provided with an offset portion 119 working in the slotted upper end of a rock arm 120 held to the forward end of a jointed and collapsible rock shaft 121. The rock shafts 121 are constructed and mounted in the same manner as the rock shafts 28 and have drums 122 fixed to the rear ends thereof. Cords 123 are secured to the drums 122 to wind thereon and may be operatively connected in any suitable manner to actuate a carriage escapement mechanism when the space bar is depressed.

then it is desired to collapse the machine the platen 59 may be lowered into close relation with the carriage 55 by loosening the clamping screws 71 and moving said screws upwardly in the slots 72 in brackets 73, thus forcing the upper ends of the links G9 and away from each other, breaking the

knuckle joints

67 and 68 of the arms (S0 and and lowering the platen 59, together with the feed roller 77 and the line spacing lever 74, from the positions shown in VFigs. 1, 3, 1, and 7 to the positions shown in Figs. 2 and 5, and materially reducing the height of the iaehine. The ribbon holder' 84 may be lowered by loosening the clamping screw 8S and movin the same upwardly in the slot S7 in the plate 85, thus forcing the upper ends of thc links 9-1- and 95 away from each other, breaki the

knuckle joints

90 and 97 of the

arms

89 and 90, and lowering the holder 81- into closer relation with the carriage bed 5G at a point in front of the platen`v59, as shown in Figs. 2 and 5.

The length. of the machine from front to rear may be materially reduced by loosening the locking screws 22 and sliding the keyboard frame part 19 rearwardly within the main frame part beneath the type basket, thus inovinjr the keyboard into closer relation vith the type bars and the platen. It will be obvious that when the keyboard frame part 19 is slid rearwardly in the guide-ways 21 in the side walls 3 of the main frame part the knuckle joints ofthe collapsible rock shafts will break upwardly permitting the front' sections of said shafts to move rearwardly until the pivot pointsv in Fig. 5. It will thus be seenthat the entions between the keys and the type bars, or

the connections between the shift keys or the space bar and the mechanisms operated thereby. When the several mechanisms have been moved into compact relation with each other, as above described, the hinged section 6 of the box-like rameor casing may be swung upwardly in front of the keyboard, the side plates 4 may be swung upwardly about their hinges 5, and the jointed cover portion comprising the hinged sections `l0, 11, 12 and 13 may be folded, as VShown in Figs. 2 and 5, to vinclose the upper portion of the machine; As shown .in Fig. 2, thesections ot the jointed cover portion rest upon the edges of the hinged side plates l andare 'supported thereby. Any suitable means may be provided for fastening the hinged sections in closed position, and any suitable means may be provided for supporting the sections ofthe jointed cover portion when the machine is extended. The hinged side plates l are provided with suitable recesses 124.-, into which the heads of the `locking screws, 71 may pass when the side plates a are swung upwardly to closed position.
