Be it known that I, BENJAMLNVW. Toom,

c. citizen of the Unitedy Stetesand .a resident of South Orange, contyoff Essex1 endjV to the carriages of typewriting mnchines inl which work sheets wider than thei cerrie'gez mov be Written upon;

This application is y endingr application Sei-inl No. IOQgCIi; filed e of the principal objects of the inyention is to provide e. con-inge :for4 a. writin machine in which a platen may be mounte and which is so constructed vthat work eheets`,`

us wide peper, long envelope, end the like, may be p need about the laten and the -work sheet handled in as remyl a. .manner as in the ordinary machine, without.` making the carriage extensible and without in any wey interferireP with the proper-working of` the parte of tie carriage or 4the `parte:nsnelly associated therewith.

Another object of the inventionris to ro vide e simple and eilcient carriage in w ,'ch.

the platen may be supported et its' ende and the work sheet so held nboutthe platen that the platen may be independently rotated. or 1 moved for line spacing, notwithstandingf s ee the fact that the work t may extend on either or both sides beyond the ends ofthe4 platen.

A furtherobje'ct of the inventionisito provide means for rotating the platen independently of the line spacing mechanism which shall be readily operable from the front of the machine irrespective of the` 4 ede-pt .thecarrlage' to move rendlly along its width of the work sheet. 1

A further object ofthe invention is to provide e simple` and efficient carriage echi ted for visible Writiing 'which may' be ree ily mede'and :resemble the parte need not necessarily occiipyfmuch Vf more space than the ordinary carrlege.

Other objects of the invention'ere-to proll'ffS 39. which "I Ily be joined tOgethel by n tubular member `or work sheet receiver 16.

-The work sheet receiver-16 maybe of open 105 wok,aswireor thin plate, either solid or 'providedffwith openings to lighten the seme,

'endif inodecf inetol, ee' elngninnm willedd be shifted downWa-r( i surface which'forms substantiall comparatively, little weight to the carri e. The end members or brackets 69 are su stantially annular in form, and each of said brackets is formed with a throat or channel 17. The member 16 is substantially cylindrical in form, and is arranged to con orm to the shape of the openings 18 in the end brackets 69. The ends of the cylindrical member 16 are not joined together, but provide a throat or opeunfr correspondin to the channel 17, in order Lthat the work eet may be caused to pass through the o )genings 1S into and from the work sheet ho der 16 as will be presently described. One end of the holder 16 is fastened to the end brackets 69 b screws or otherwise, and the other end of tlie holder 16 may be provided with upturned parts or lugs 2U, by which said en'cl may be seclu'ed by screws 21 or otherwise, to the outer surface of said brackets 69.

The end brackets 69 are extended forwardly to provide lugs 22, and mounted in said lugs to rotate therein is a platen 71. The platen is supported at its ends in the lues 22 in brackets 69, and extends substantia ly throughout the entire ,distance between said end brackets, and is adapted to take the impact of the type in theusual way. The pressure roll is held to rotate in a yieldably supported frame 25 hinged to the carriage frame at 26,l so as to be adapted to sure roll from the platen 71. The carriage frame part 25 has a plate 33 on its upper a continuationof the forwardedge of t c holder 16, and said plate with the plate-like cylindncal member 16, provides a proper surface for guidi Ythe Work sheet backwardly or forwardly etween the platen and pressure roll without offering any obstruction thereto. The plate 83 is out away to permit the roll 70 to extend through the same, and said roll is also .out away to provide spacedmembers or parts 34, between which partsva .part of the late 33 extends in order that a substantiny continuous tablelmay be provided for the work sheet. A handle 35 may be arranged at either or both sides of the machine on the pressure roll 'frame 25 to adapt said frame to be moved about the spring hinge 26, to release the pressure roll from the platen to adapt the work sheet to be ad"- justed. By this means the work sheet may be properly held and fed between the platen 71 and the pre'lu'e roll 70, either into the holder 16 or forwardly for printing purposes, as desired. The construction of the yieldably su ported pressure roll frame 25 1s substantie. ly the same es that shown in Figs. 1 to 6 of my copending a lication Serial No. 100,037, tiled May 26, 1S 6.

The platen 71 may have thel usual roll member with the impact receiving cylindricel covering ofrubber or other materiahand I ly to release the presin one end thereof may have a bushing 72 and at the other end may have a bushing 73. The bushing 72 has a stemor stud portion 74 projecting outwardly from one side thereof, and this stein has a reduced` part entering an opening in one of the carriage end brackets 69 to rotatably support the platen at one end in the carria'fe frame. The bushing 73 is provided widi a central opening therethrol'xgh, and extending through the opening is a shaft or rod 75. The rod 75 extends throu h an opening in one of the -1u 22 forme on the carriage end bracket adjacent to the bushing 73, some distance into the platen and at one end is provided witlra knob or button 76. At the opposite end of the rod 75 within the platen is a key 77 which is adapted to engage a slot or key- Way in a collar 78 forming a part ot' the platen. The key 77 permits the extension ofthe rod 75 so that said rod ma be made to rotate the platen Whether the 'nob 76 is close to the end bracket of the carriage or at a distance.V therefrom. This permits the platen to be -rotated manually at will in either direction independently of the line spacing mechanism in case the work sheet is Wider than the carriage is lone.

The rod 75 may be grcovef at intervals, 'as at 79, and adapted to engage said grooves is a latch 80. The latch S0 is pivotcd at Sl to the carriave frame and is normally forced in one direction b a spring 82. The latch is provided wit 1 an opening' Sl through which the rod 75 passes and said opening provides an engaging part 84 to enter one of the grooves 79 to prevent the rod from being extended or forced into the platen and to hold the same in its adjusted position until the latch is released. The latch 80 isv substantially bel1-crank in form, and on one arm thereof is provided with a finger key or part 85 by which the latch may be depressed, as shown in Fig. 5, to release the same from engagement with any one of the grooves 79 and thereby permit adjustment of the rod 75.

The platen is rotated for line spacing through n 'ratchet Wheel S6 fixed on the stem 74 of thelbushing 72. This ratchet Wheel S6 is adapted to be engaged by a paw] S7 which 'is pivot-ally held to a lever 8S and is normally pressed by a sprin v 894into en ;agement with the teeth of tie rati-het wheel. The lever S8 is plvotally held to the stem 74 land is connected` by a4 link 90 to a lever 91.

The lever 91 is pivoted at 92 to one ot the 'carriage brackets-and has a finger portion 93 located at the rear of the carriage. The

spring or otherwise, andthe extent of movement of the lever 8H may be limited bye manually movable stop 94 in substantially the same manner as the line spacing action of the pawl is controlled in` the (orona typewriter. rl`he platen may also be held in its various adjusted positions by a friction roll, as 95, which is supported at the end of a spring held lever 9G, and which engages a 10 platen and still permit it to be rotated in either direction.

'lhe carriage may be provided with aper lingers 34, which are adjustably heh to a bar (35 carried by the pressure roll frame 25. T hose fingers may be adjusted lengthwise of the platen, und at the upper end thereofma have rolls (56 mounted thereon, as is usua The pressure roll frame 25 may be provided with a scale (37 at the forward edge thereof, and there may be also provided type 'alining means (3H which may be hinged to adapt the same to be moved with the pressure roll away from the Jlaten.

It will be evi cnt from the foregoing that a carriage construction is provided whereby wide or long work sheets may be employed and written upon which are wider than the length of the carriage or the platen; that 80 simple means are provided whereby the work sheet is pro erly held between pressure.

means and the p aten; that the construction is such that the carriage is adapted for front strike or other writing means, and that simple and efficient means is provided' whereby the work sheet may be readily adjusted and line spaced irrespective of the width thereof.
