Specification of Letters Patent.

Patented Aug. 11, 1914.

Application filed June 28, 1912. Serial No. 706,361.

T0 all whom it may comer).

Be it known that I. CLIo B. YAw, citizen of the United States, and resident of Arlington, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in rlype-lVriting Machines, of which the following is a specification.

My invention relates to stencil or card writing mechanism for typewriting machines and its general object is to provide improved mechanism of the character specitied.

More particularly one object of my invention is to provide an improved stencil or card container.

Another object is to provide improved stencil or card guiding and feeding mechanism.

AXnother object is to provide improved ribbon mechanism which promotes the visibility of the writing on a stencil sheet.

Another object is to provide full stroke devices in connection with stencil or card feeding devices.

Other specific objects will hereinafter appear.

To the above ends my invention .consists in the features of construction, combinations of devices and arrangements of parts to be hereinafter described and particularly pointed out in the claims.

The preferred form of my invention is herein illustrated as applied to a No. 10 front-strike Remington typewriting machine, although the invention may be applied in whole or in part and with various necessary or desired constructional changes to other styles of writing machines.

In the accompanying drawings, Figure l isa fragmentary front elevation of the u per part of the No. 10 Remington typewriting machine embodying my invention, parts -of the machine being shown in section. Fig.

2 is a corresponding rear View. Fig. 3 is ,a side elevation of said machine, parts being shown in section. Fig. 4 is a vertical front to rear central sectional view taken about centrally of the machine and illustrating certain of the stencil guiding devices as applied to said machine. Fig. 5 is a vertical front to rear sectional view taken on a plane indicated by the dotted line in Fig. 2

and looking in the direction of the arrow at said line. Fig. 6 is a fragmentar perspective view of the floor or bottom plate of the stencil holder and its mounting. Fig. 7 is a fragmentary longitudinal sectional view of the ribbon spool or holder.

As appears especially from Figs. l, 2 and 4 the main frame of the machine comprises a base 1, posts 2 and a top plate 3 supporting stationar rails 4 which coperate through anti-fiiiction balls 5 with the truck 6 of a platen carriage which further includes a platen frame or carrier comprising end bars 7 and a cross bar 8.

The platen frame supports a rotary platen 9 which preferably is of the usual construction except that as shown in Fig. 2 there is a central section or ortion 10 which, instead of being of ordinary rubber composi tion, is of Celluloid, this Celluloid section replacing the usual rubber sheath, which however remains at the ends. In assembling the parts one of the rubber end portions is arranged on the usual wooden core and then the Celluloid section is slipped on to the core and suitably secured in place, after which the other rubber end portion is put on. The central Celluloid section provides a hard backing for the stencil sheets and c0- operates with the types properly to cut-and impress said sheets. I have found in practice that by providing a hard surface, such as Celluloid, for cooperation with the ordi-I nary types, satisfactory stencil cutting operations may be performed. so that if desired the usual needle pointed types employed in stencil work may be dispensed with.

The platen frame 7, 8 on which the platen 9. 10 is rotatably mounted is connected with the truck 6 by links 11, and is shiftable up and down thereon by devices comprising a key controlled shift rod or bar 12 which provides a track-way for a roller' 13 journaled on the cross bar 8. Printing movements of the carriage and platen are controlled by a spring motor or drum and letter feeding devices not herein disclosed but which are of the ordinary style. Type bars 14` each provided with an upper and a lower case type, are journaled below the platen on a supporting segment 15 and are connected with printing key levers 16 by a train of devices comprising for each type bar a link 17, a lever 18 and a second lever 19. The actuation of each lever 18 causes its associate type bar to cooperate with the front face of the platen and also effects a letter feed movement of the carriage.

Referring to Figs. 1 to 3, 5 and 7, the box or container for the cards or stencil sheets comprisesl two vertical end plates 20 connected near their lower ends by cross bars Q1, the cross bars and end plates being rigidly secured together b v screws 22, thus forming a rigid frame. This frame is rotatably mounted on a rod Q3 connecting the end bars 7 of the platen frame and secured to rearward extensions of said end bars, said cross rod 23 being one. of the regular parts of the platen frame. The body portions of the end plates are turned or bent outwardly at their tops providing a flaring mouth to facilitate the introduction of stencil cards while forward of the mouth portions the plates Q0 extend upward for purposes hereinafter described. The cross bars 21 supporty a floor plate 24 provided at its forward side with a downwardly extending lip 273, said floor plate being provided near its rear edge with parallel slots 2G (Fig. 6) which receive headed screws Q7, said screws engaging in the rear cross bar 21 and adjustably securing the floor plate to its support. 'A front plate 28 is arranged between the end plates 20 and is provided at each corner with a forwardly turned ear Q9, which ears are secured to upward ,extensions of the side plates by screws 30. The end plates are provided with hubs 31 through which the platen frame rod passes, the container thus being pivotally mounted at its rear on the frame rod 23. The forward ends of the end plates are provided with integral arms 32 which are curved downward at the front side of the platen and rearward under the same and rest at their lower ends against the front face of the platen frame bar 8 which thus serves as an abutment or support. The weight of the container and the parts carried on and supported thereby assists to maintain said container in normal position with the arms 32 in contactive engagement with the bar 8 in Figs. 3 and rllhe container and the parts supported on it are inlapted to be swung upward on the rod 23 as an axis, the movement being limited by the engagement of the ends of the arms 32 with the face of the platen, this movement bein;` for the purpose, among others, of facilitating the adjustment of the ribbon hereinafter described. 'l`c assist in restoring the container to normal position and also to maintain it in such normal position, a restoring `spring 3i.- niay he provided. said spring being coiled around the rod Q3 at the lefl of the container and having one end engaged in the left-hand hub 31., the other end being anchored to a collar 34 screwed to the rod 23. At the opposite end of the container a second collar 35 is screwed to the rod 23, this collar 35 preventing sliding movement of the container along the rod in one direction, while the spring 33 and its collar 34 limit sliding movement in the opposite direction, this construction being clearly shown in Fig. 2. A5 appears in the front view, Fig. 1, the front plate 28 is provided with a series of parallel vertical slots 36 giving a view of the cards in the container and lightening the same. Between the outermost pairs of these slots 36 there are secured to the front plate by screws 37 vertical retaining springs or detents 38 which extend downward and at their lower ends curve rearward through slots 39 in the front plate, said springs being adapted to engage with the foremost of the stencil cards or sheets. Thesestencil cards or sheets, designated in the drawing as 40, are or may be of the usual style comprising a rectangular frame of card board to which the stencil paper is pasted. These stencil cards are arranged in a pack within the container behind the front plate and resting on the floor plate. The pack is constantly pressed forward toward the front plate by a follower or pressure device in the form of a plate 41 arranged within the stencil container between the side plates thereof and resting on the bottom plate, said plate 41 being adapted to travel forward and rearward toward and away from the front plate 28. The follower late 41 is provided with rearwardly extcndping ears 42 which are pivotally connected at 43 to the forward ends of parallel links 44, said links extending rearward and being pivotally connected at 45 to upright arms 46 and 47. These arms are provided with hubs 48 which` as shown in F ig. Q, are secured by screws 49 to a sleeve or hollow rock shaft 50 which bears rotatably 0n the rod 23, the sleeve rigidly connecting the arms 46 and 47 and providing with them a rocking frame for controlling the follower plate through the links 44. The rocking frame is confined between the end plates Q0 which maintain it in proper posi tion on the rod Q3. The arm 47 extends upward out of the stencil container and is provided with a lateral finger piece, handle or key 5l for swinging the rocking frame rearward `and retracting the follower plate when a fresh pack of stencils is to be in scrted in the container. A draw spring 52 (Figs. 1 and 2) is anchored at its forward end to a pin 53 projecting from the left-hand end plate 20, the rear end of said draw spring being hooked over a pin 54 which projects laterally from the arm 47. Said spring tends constantly to draw the rockin frame forward and maintain the follower plate in spring pressed engagement withthe pack of stencils which are thus compressed between the follower plate 41 and front plate 28. By reason of the pivotal mounting of the follower late it adjusts itself readily and is thrustgy the spring pressed links 44 into contactive engagement with the rear- 'most stencil card throughout substantially its entire surface. The floor plate 24 is so set in respect of the front plate 28 that a narrow mouth or Slot way is provided between the lip 25 and the lower end of the front plate, this mouth being adjusted a width just sufficient to permit the easy passage downward therethrough of one stencil at a time.

It will be observed especially from Fig. 5 that the parts are arranged so that the stencil or card container overhangs or overlies the platen while the mouth or opening is in substantial vertical alinement with the printing face of the platen. The friction springs 38 coperate with the lower end portion of the foremost stencil card that is to be ejected as appears from Fig. 5, and while readily yieldable when force is applied to eject the stencil, nevertheless prevent the stencil from dropping down accidentally through the slot 55. Also the upper end portion of the middle part of the front plate is turned back to provide a ledge 28 which overlies the foremost two or three stencils and prevents an upward displacement thereof which wou d tend to force them out of the stencil container.

Devices are provided for ejecting the stencils one at a time from the container, the stencils being forced down through the slot 55 and located at the front side of the laten infposition to receive the first line o writing by a single continuous movement. The stencil or card ejectin or feeding devices are hand-controlled an comprise, as shown in Figs. l to 3 and 5, a gravit frame composed of parallel arms or mem ers 56 and a comparatively heavy cross bar 57 which serves as a weight and to which said arms are rigidly secured by screws 58. Said arms are provided at their inner faces with small rollers 59 to travel up and down over the front plate 28. The arms 56 also lcarry stop pins 60 extending laterally from their inner faces, said pms also coperatin with the front plate; The arms 56 are ormed with open slots 6l which fit over and embrace a traveling shaft 62, said shaft providing a vertically reciprocatory support or carrier on which the gravity frame 56, 57 is pivotally mounted. The shaft or carrier 62 is horizontally arranged in front of the plate 28 and is reduced at its ends as indicated at 63, the reduced ends engaging in vertical guide slots 64 cut in the forward and upwardly extended portions of the end plates 20. Small pinions 65 are secured to the shaft 62 near its ends, said pinions meshinv with rack scetions 66 which are vertically arranged at the sides of the front plate '28 and are suitably secured thereto, the construction being such that the traveling shaft 62 is forced to travel evenly and skewing of it and also of the gravity frame is prevented. The cross bar or rod 57 tends because of gravity to swing forward on the shaft 62 as an axis and to force the lower ends of the arms 56 rearward toward the stencils through vertical slots 67 cut in the front plate 28 just inside the rack sections 66. This rearward movement of the arms is limited by the rollers 59 contacting with the front plate 28 at the inner sides of the slots 67. Accidental displacement of the gravity frame from the shaft 62 by forcing the rod 57 rearward over the shaft is prevented by the cooperation of the stop pins 60 with the front plate. The construction is such that the gravity frame is loosely hung or mounted on the traveling shaft 62 and may swing freely thereon within limits but is prevented from undue movement as described. The lower ends of the arms 56 are flat and are normally horizontal, so that these ends are adapted for ready engagement with the stencil cards. The movements of the gravity feeding device 56, 57 are controlled b an actuator or hand lever 68 provided with a hub portion 69 which bears on a screw pin 70 projecting laterally from an ear on the left-hand end plate 20. The lever 68 has a downward extension or tail piece 71 having a pin 72 at its lower end over which is hooked a draw spring 73, said spring extending forward parallel with the spring 52 and being anchored to the pin 53. The lever 68 normally inclines forward and upward at the left of the stencil container, the forward end of said lever turning upward and being provided with a finger piece or key 74 which normally projects above the container and to the left of the same where it may be readily grasped and operated. The lever 68 is formed with an elongated slot 75 which engages a flanged roller 76, as clearly shown in Fig. l, said roller bearing rotatably on the reduced left-hand end 63 of the shaft 62, said end being extended leftward and threaded to receive a hexagonal nut 77 which confines the roller 76 to its bearing and also prevents lateral displacement of the lever 68. Acting through said lever the spring 73 maintains the shaft 62 at the top of the iide slots 64 and restores said shaft and t e gravity frame to the ulppermost position after actuation. When t e parts are in the normal position the lower ends of the arms 56 are swung rearward through the slots 67 to the limit of their movements and overlie the upper edge of the foremost stencil card 40 near its ends. When a stencil card is to be ejected the key or finger piece 74 is forced downward to the limit of its movement as shown in Fig. 5, this limit being determined by the engagenient ot' the ends ot the shaft 62 with the l stencil card a units distance apart, and the bottoms of the guide slots o4. The actuation i of the lever tS ibeiatcs to torce the shalt *l2 downward. said shalt turning on .it` axis as it nioves bodily downward bv reason of the internieshing pinionsr and racl-is of). (lo and cai'ijvinet bodily with it the gravity trarne In?. 5T, the rollers whereof tiavel over the face ot' the front plat-e of the arms 5h engaging with the foremost stencil card will, as the gravity traine moves down Yard. force said card to move continu oizsly down through the slot until it reaches` the position shown in Fig. 5 in which position it is adapted to receive the. liistline et writing. lt will be observed that at this time the upper end ot' the stencil card is still within the slot 57i .so that during subsequent line spacintr movements in writingr the stencil the caru will returnf upward step-b v-siep through the slot .35. At the end ot the ejectine operation. the lever (3S is released. and as the cjeciing device returns upward under the cilntrol ot the spring 73 the rear lower ends ot the arms 56 will slide over the front of the side portions of the next .st ncil card novv at the iront of the container. As soon as said arms are lifted above the upper edge of said card` said arms. will swingr bach trom thel force ot' gravity acting through the weight or rod This swinging movement carries the .ower ends of the arms backward over the iop ot said steiicil card and in position to luggage with it during the next. ejecting operation.

The line spacing or upward movements of 'the stencil are caused by feeding devices which cooperate with the platen when the platen is line. spaced by the usual line spacing: devices comprisingt ratchet wheel and i.and actuated pawl 79 (Fig. 2i. Said sincil feeding devices conipi'ise rollers SO, preferably ot' metal` which cooperate with tt rubber portion ot the platen beyond the und ot" the central celluloid portion 10. as 'rcni Fie. 1. The feed or pressure 1@hers S0 are pivotally supported in carriers ttl which in turn are pivoted cn and depend troni :f cross rod S2 secured at its ends by screws .s3 to the lower front portions 'thc enti plates 2t?.

Usually there are three lines written on each The ends part :irc so prolmrtioned in the present instan' that when tir iartiv e ectcd stencil card la been retracted or spacol upward three units` distances from the position shown in Fig'. .3. its upper odge will be in register with and contiguous :o thil lower eder- -l' the ncvt stencil to he ejected, This neat. stencil will now bein register with the `ht .35. it beine4 understoml that as soon as the hot stencil was ejected past the floor plate thc rc-iiiainder of the pack in the container was forced forward by the spring prevail toiloaer plate ll. The result Will he that en the next downward actuation of the a: tuatoi' o5 thc second stencil card will be ejected from the container and during its ejection will force the underlying written stencil sheet down out of trie machine over .gfuidinei dc\ ices next to be described. It will lie-understood that after the first operation, then. oi' the actuator each subsequent oper ation will have the c1l`cct ot forcing a written stencil out of the machine and of positioninteY the next succeeding stencil in position to receive the tiret line ot writing at the front of the platen.

Guiding devices over which the Written stencil cards pass ont of the machine are clearly illust-rated in Figs. l. 4 and i and comprise a plate 8T which is preferably of a light material such as aluminum, said plate being provided with ears 88 which are sc` cured to the sides of the top plate forward of the platen by screws 89, Washers 90 being' preferably interposed between the heads of the screws and the ears 88. The plate 87 is preferably of about the Width of the type basket at its upper end, this Width being su'licicnt to allow for endwise movements of the stencil from one side to the other. Said plate 8T extends from slightly in front of the platen downward over the rear ol' the type segment, inclining toward the rear of the machine and terminating just back of the base 1. The `guide plate 87 narrows as it approaches the rear and its sides are turned up somewhat as indicated at 91 so that the plate forms a shallow trough or chute. A continuation 92 of the guide plate 8T may be made separate.r if desired, said continuation being U-shaped in cross section as shown in Fie'. 4 and being secured to the rear of the base by .screws 93. The lower end of the guide plate or chute 87 preferably overlaps the upper end of the plate 92 and the overlapping portions receive the screws 93 which thus secure the lower end of the plate FST and its continuation 92 in place. The continuation 92 is of a width fore and aft sullicient to accommodate the stencils as they slide down over the chute 87 and rest on the bottom of the plate 92 which has no' ends nor top, so that the stencils may readily be removed. There is thus provided a guide comprising two portions 87 and 92, the sides of which are in planes at right angles to each other. 1

In prior constructions it has been difhcult during the course of the writing to sc e clearly what has been printed on stencil cards, the impressed letters being hard to decipher unless the stencil cards were removed and held against the light. Consequently mistakes in the writing are sometimes not detected until the stencils have been written and removed from the machine. In order to overcome this objection I provide a ribbon which is arranged behind the stencil card, when the latter is in writing position, said ribbon being interposed between the stencil card and the platen. In the course of the Writing the ribbon offsets on the back of the stencil and clearly outlines the characters as they are printed, thus providing a sort of indicator for the printing.

The ribbon aforesaid, designated herein by the numeral 94, is controlled by novel feeding devices now to be described. Said ribbon is preferably of a width corresponding to the length of the stencil platen 10 and is stored in roll form on a holder, carrier or spool comprising a hollow hub portion 95 and flanges 96 (Fig. 7). The spool is arranged at the rear of and above the platen, being supported on the rocking frame 46. 47, 50. One end of said spool is connected to and supported on a stud shaft 97 which bears in a boss or hub 98 rigid on the arm 47. The end of the hub 95 adjacent the shaft 97 projects outward beyond the flange and fits over the end of the stub shaft, being provided with a notch or slot 99 which engages a pin 100 on the shaft, thus connecting the parts so that they are compelled to rotate together. A cap 101 is arranged outside the boss 98 and secured to the shaft by a screw 102, said cap assisting to prevent The opposite i displacement of the shaft. end of the spool core 95 fits over the inner end of a shaft 103 having a reduced portion 104 threaded at its end and provided with a thumb nut 105. The reduced portion 104 of the shaft bears in a bushing 100 secured in a hub or boss 107 fixed to the arm 4G, the inner enlarged end portion of the shaft 103 bearing directly in the boss.

Arranged between the portion 103 and the bushing 106 is a compression spring 108, said .spring surrounding the reduced portion 104 and tending constantly to press the shaft inward toward the spool. this movement bei limited by a flange 109 on the. shaft. pu ling outward on the thumb-nut or finger piece 105, the spring 108 is overcome and the shaft 103 may be withdrawn from the spool which may then be readily detached from its supports. An automatic rotary movement 1s given the spool to feed the ribbon bv devices comprising a ratchet wheel 110 which is rigid on the shaft 97 (Figs. 2, 3 and 5.) Cooperative with the teeth of said ratchet wheel at the under side thereof is a feeding pawl 111 pivoted at 112 to the inner face of the left-hand end plate 20 and maintained in engagement with the ratchet wheel 110 by a spring 113 coiled around a boss 114 `in which the pivot screw 112 is secured, said spring 118 bearing on the pawl 111 and constantly pressing it upward. The upward movement of the pawl is limited by astail piece 115 which contacts with the rear cross bar 21, the floor plate 24 being notched out as indicated at 116 to permit of this con-L tactive engagement. The hub 48 of the arm 47 is cut away as indicated at 117 (Fig. to permit of downward swinging movements of the pawl 111 to a limited extent. A coiled spring 118 is arranged on the shaft 97 between the ratchet wheel 110 and the arm 47 and not only serves to maintain the shaft 97 pressed inward with the head of the screw 102 against the cap 101 but also serves as a friction spring to prevent accidental or abnormal turning mo\en1ents of the ribbon spool. The ribbon is drawn off from the rear under side of the roll of ribbon 94 as appears from Fig. 5, the unwound portion passing forward under the stencil container and being supported on and guided by a guide plate 119, said guide plate being coiled around the sleeve 50 and pivotally supported thereby, said guide plate eXtending forward and its free end resting loosely 011 the top of the platen. The ribbon 94 passes from the guide plate down over the front side of the platen and between it and the stencil card that is positioned for writing, the loose or free end of the ribbon passing out at the rear of the machine over the guide plate 87.

It will bey observed that the pawl 111 is pivoted io a relatively fixed part, i. e., the stencil container itself, while the ratchet wheel 110 and the ribbon spool are mounted on the rocking frame comprising the sleeve 50 and the arms 40 and 47. The construction is such that when the linger piece 51 is pulled back to retract the follower' plate and enable a new pack of stencil cards to be inserted. the ratchet wheel will nove bodily. Since. however, the pawl 111 iemains stationary and engaged between two of the teeth of the ratchet wheel. said ratchet wheel will be subjected to a rotary movement on its longitudinal axis as well as a. bodily swinging movement on the axis of the shaft 50. This rotary movement will be transmitted through the slot 99 and pin 100 to the ribbon spool and the ribbon` unwinding the ribbon to a corresponding extent, in the present instance about one-eighth of an inch. The parts` are proportioned so that each time the follower plate is retracted from the front plate to its ful. extent, the ratchet wheel 110 will turn to the extent of a single tooth. The rearward movement of the follower plate is limited by pairs of stop pins 120 which project inward oppositely from the end plates 20. The arm `'i7 is cut out at its forward edge as indicated at 121 so that the forward movement of the follower plate will not be obstructed by the engagement of the arm 47 with the upper left-hand limiting pin 120, the notch permitting the follower plate to be forced into contact with the front plate 28 by the spring 52 when all of the stencil cards have been ejected. As the follower plate advances intermittently during the stencil ejecting operations, the pawl 111 will slide inactively over the teeth of the ratchet wheel 110 which will not turn on its axis to feed the ribbon, but the ribbon spool will advance bodily with the rocking frame and the unwound portion of the ribbon will also advance correspondingly. Both the ribbon spool and ribbon will be retracted to the same extent when the follower is retracted.

From what has been said it will be understood that the ribbon is fed off the spool a unit distance each time a pack of stencils is introduced into the machine; that each card will be written on a different part of the ribbon due to the bodil'v forward movement of the ribbon spool; and that the same portion or section of the ribbon used with one stencil pack is also used with the next pack except for the one-eighth portion advanced permanently below the printing line when the follower is retracted and the spool turned axially. The capacity of the present device is some twenty-four or twenty-live stencil cards so twenty-four or five lines or a multiple thereof may be written between axial turning movements of the spool. The ribbon is used until practically exhausted, so that when said ribbon is fed down and back out of the machine it is used up and useless and may be cut off at intervals and thrown away. When the ribbon roll is completely exhausted a fresh ribbon may be applied to the ribbon spool. It will be understood that it is not necessary that the ribbon should make perfect impressions on the back of the stencil card but only that enough ink should be supplied to enable the character printed to be read easily through the stencil, this ink, of course, not being of any service subsequently in reproducing the impressions cut in the stencil card.

In order to insure that the lever or actuator 63 may be actuated to the fullest extent in ejecting the stencil cards, I may provide devices in the nature of full stroke devices which may comprise a pawl 122 pivoted at 123 to the extension or ear 20a behind the pivot 7() (Fig. 3). Said pawl is maintained in its intermediate or central horizontal position by a two-arm spring 124 secured to the inner face of the ear 20a at 125, the free ends of said spring being bent outward over the top and bottom edges of said ear and engaging with the sides of the pawl 122 forward of its pivot. An extension or finger 68a preferably integral with the lever 65 projects rearward from the pivot and is provided at its ends with notches 126 which are adapted to coperate with the pawl 122 when the lever 68 is swung downward. If the lever 68 is swung down to its fullest extent the finger 68a will swing upward past the pawl which, after the passage of the finger. will return to its normal central position; but if the stroke of the lever 68 should not be completed, then the pawl will be left iu engagement with one of the notches 126 and will thereupon cooperate with the finger (33a to hold the lever (SS in the position in which it is left when the operator fails to complete the stroke to itsl full extent. The operatoi` is thus notitied that the stroke has not been completed7 and needs oniv further to depress the key and the lever G8 to the limit of its movement to release the finger (58 from the control of the pawl 122. During the return movement the pawl will be forced downward from its intermediate position to permit the finger 68a to swing past it.

It will be observed that the stencil or card and associate devices are mounted on a shiftable platen frame or carrier so that the ccntainer shifts with the platen, enabling both the capitals and small letters to be printed on a stencil sheet.

It is to be understood that rthe invention is adapted for use with forms of work sheets other than stencil cards; and that various changes may be made within the spirit and scope of said invention.

IVhat I claim as new and desire to secure by Letters Patent, is :h

1. In a tvnewriting machine, the combination of a platen carrier. a platen thereon, and a card container overhanging said platen and pivotally supported on said platen carrier and provided with arms which rest against an abutment on said platen carrier. said container being supported independently of the platen.
