will be understood, however, that the style of the frame is not material and that it may be modified as desired by a skilled constructor.. The posts 7 are parallel and located at the rear corners of the frame, said posts being hollow to form the vertical'ohannels or guideways 8, adapted to receive the slidable stems '9, which support the frame for thecarriage, in which is mounted a platen 10, The posts 7 are provided in their front sides and at their lower ends with slots 11,which accommodate the rear end of a lever 12 and an arm-13. Said lever is disposed on one side of the machine, as shown To all whom it mayv concern: Be it known that I, FRANK S. ROSE, acitizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented a new and Improved Type-Writing Machine, of which the follow- 'ing is a full, clear, and exact description. This invention relates to improvements in type-writers, in which I seek to produce a new construction of the support or carriage for the type-platen or cylindrical roller which enables the same to. be folded into compact relation to thekeyboa'rd, thus making provision for ready and convenient transportaby Fig. 5, while the arm 13 is on the opposite 15 tion of 'the instrument. side of the machine. The frame is provided 65 Another object that I have in view is to with depending bearings 14, in'which is jourprovide improved means for shifting the naled a horizontal rock-shaft 15, the same beplaten relatively to the point of impact of the ing disposed below the banks of key-levers to type-faces on the type-levers. be presently described. The arm 13is secured 7 Further objects and advantages of the in-. rigidly at its front end to the rock-shaft 15, 7o vention will appear in the course of the subwhile the lever 12 is bent or offset at a point intermediate of its length, as at 12, said offset portion of the lever being secured rigidly to the rock-shaft 15 near the other end fromlt will be understood that the joined description, and the novelty will be defined by jhe annexed claims.

Reference is to be had to the accompanying and the stems 9 is suflicient to overcome the tension of the'springs, 16, so that the platen will normally remain in position to' receive the impact of the lower-case type on the heads of the type-levers to be presently described, 10

but in the drawings this frame consists of the side bars 5, a yoke-shaped front bar 6, and the posts 7, said parts being united in any preferred way and presenting a substantial 5 construction for the working elements. It

The lever 12 o Fig. 5 is an inverted or under plan view of extends practically from the front portion to the type-writing machine, the rear portion of the main frame, and this The several working parts of the improved front end of the lever is equipped with a suitmachine are mounted on a suitable frame, .able key 12". The weight of the platen and '45which may be of any desired construction; the carriage imposed on the carriage-frame ver 12, and the rear end of Ver is'bent downwardly, as

. engages with posed in the path of pressed and these springs 16 serve to normally hold the lever 12 and the arm 13 in engagement so that the numerals and. punctuation-marks on the type-heads of the type-levers may be pressed against the platen; but to bring the platen -and the carriage into position to re? ceive the impact of the upper-case type on the type-levers'I employ an auxiliary shifting-lever 18. This auxiliary shifting-lever is arranged alongside of theprimary shifting-lesaid auxiliary leat 18", and connectedpivotally by a pin 18 to the lever 12 at a point in rear of the offset portion 12. Said lever 18 is also-provided with a key 19 and with a laterally-extending finger 20, the latter being arranged to project laterally from the key- 19 and to rest upon the front portionof the shifting-lever 12, as shown more clearly by Fig. 1. The auxiliary shifting-lever is thus pivoted at one end to the lever 12 and provided at its other end with a finger which said lever 12, thus insuring a si-' multaneous movement of" the levers 18 and 12 when pressure is applied to the finger-piece 19; butas the platen and the carriage should not be raised as high when the lever 18 is de;

as when the lever 12 is likewise actuated I have provided a stop 21 on one sidebar 5 of the main frame, said stop 21 being disthe finger 20 and arranged to limit the depressing movement of the auxiliary shifting-lever 18.

,The important features of the present inventlon is the provision of means whereby the platen and its carriage may be folded into compact relation to thebanksjof keys, thus making provision for convenienttransportation of the instrument. In carrying out this part of the invention I employ a foldable sectional construction of a frame adapted to support the carriage and the platen, and in the. drawings this-frame is shown as -consisting of two main parts, one of which is carried by the adjustable stems 9,'while the other part is. pivoted to the'non-foldable part and serves as a track for the platen-carriage.- The non-fold ing part of the carriage-frame thus far described" consists of arms 22 23, arranged in horizontal positions to extend from the front having their rear portions secured firmlyto said stems. The folding'part of the carriage-frame consists of arms 24 25 and a base-plate 26. Said arms 24 25 platen are adjusted in their and the the plate 26 by means ofone or more blocks of the foldingimember of the carriage-frame normally lie alongside of the arms 22 23, and the twopairsof arms are pivoted directly together, as at 27 in any suitable way. Said" 'pivoted arms 24 25 are arranged to rest upon the arms 22 23 when'the-carriage and the tions, as in Figs. 1 to 4, inclusive, thus sustaining the two parts of the frame in compact relation and skeletonizing the frame, .so that the type-levers may work between the arms in a way to strike against the platen 10.

The base26, constituting a part of the movable member of the carriage-frame, consists in the embodimentof the invention shown by the drawings of a flat plate having an upstanding flange 28, and this base-plate is rigidly secured to the rear ends of the arms 24 25, the latter being somewhat longer than the arms 22 23. The base-plate 26. joins the arms 24.: 25 rigidly, and this plate and its flange form the track-surfaces for the endwise-movable carriage, which, as in ordinary type-writing machines, is capable of a traveling stepbystep movement under the control of a suitable spring and an 'escapement mechanism. The upstanding flange 28 on the plate 26 has its upper edge arranged to form one of the track-surfaces for the carriage of the rollerplaten, while the top face of the plate 26 affords the other track-surface for a roller of the platen-carriage to be presently described.

The carriage consists of a longitudinal rail 29, a pair of brackets 30, and a tie-rod 31. The brackets-30ers rigidly secured in a suitable way to the rail 29, and these brackets are joined bythe tie-rod 31, which serves to hold the brackets in firm relation to the rail and in parallel relation to each other. The rail 29 is fashioned to ride or travel directly uponthe track-surface afforded ;by the upper edge of the flange 28, :forming a part of the plate 26, carriage is held in proper relation to 32, secured to the rear face of the flange '28, said block or blocks being provided with a lip 33, arran'ged to slide in'a groove 34 0f the operative posirail 29, as shown more clearly by Fig. 4 of the drawings. 1 The brackets 30 are provided with openings adapted to receive the shaft of the rollerplaten10,.the latter being free to turn in the bearings aiforded by said brackets. This platen maybe of, any suitable construction known to the artas, for instance, acore covered by a rubber jacket-and said roller is provided at one or both ends with suitable gripping-wheels 35, by. which the roller may be conveniently turned by hand. The brackets 30 are also connected at their front ends by a rail 36, which is disposed below the rollerplaten and fastened at its ends to the brackets in any approved way, and this rail 36 has a track-roller37 mounted thereon in a way to turn freely,

the plate 26 of the carriage-frame. The carriage isadapted to carry a ratchet-bar '38, which maybe'fastened to the brackets 30 or to the rai'l'36', and with the teethof this ratchet-bar are adapted-to engage the pawls of a suitable escapement mechanism. It is tobe understoodthat the carriage and the platen said roller. riding on the track der44, pivoted by a pin 45 to "and 4) the lower-case type ing a finger-piece the inked ribbon against thework, theoperator should depress the auxiliary shifting-key. 18 until its finger 2O strikes the stop 21, and this movement of said lever 18 causes the nger 20 to depress the'shifting-lever 12, where- 7 by the shaft 15 is turned and the lever 12, together with the arm 13, raises the posts 9 a limited; distance, thus bringing the rollerplaten 10 into position to receive the impact of the upper-case type. To utilize the type representing the numerals or punctuationmarks, the operator should depress the keylever 12, thus turning the shaft 15 and operating the arm 13 simultaneously with said lever 12 to elevate the carriage and platen to the highest point, as represented by Fig. 3, thus making the platen take a position in the path of the outermost type type-levers 43. As before indicated, the ten-, sion exerted by the springs on the key-levers may be varied by adjusting the rod- 64 to change the positions of the plates 63'and the rods 62, thus slackening or increasing the tension of the springs 61. When it is desired to carry or transport the machine, the carriageframe, together with the carriage and the platen, are adjusted by turning the arms 24 25 on the pivots 27, which connect said arms with the non-adjustable member of the carriage-frame; y turning the arms 24 25 and 5 the plate 26 in a forward and downward irection the position of the carriage and the platen is inverted to assume the compact relation to the banks of keys indicated by dotted lines in Fig. 2. The carriage and platen may be allowed to rest on the keys; butI also contemplate the employment of adjustable rests, which may be embodied in the form of plates 65, which are pivoted to the sides 5 of the machine-frame. Said plates are provide with concave free edges to snugly receive the platen 10, and the plates are held in their raised positions by the engagement of the platen therewith.

The improved machine of my invention presents a compact construction and arrangement of parts. It is light in weight and easy'and convenient to operate' The coiled springs 16, which are connected to the arm 13 and lever 12, not only hold these I I 5 parts in engagement with the slidable stems, but also assist in raising the stems and the weight imposed thereon, thus insuring easy motion to thelifting of the platen-carriage on the depression of either of the shiftingkeys.

It is evident that any suitable means may be used for holding the foldable member of the carriage-supporting frame in, its normal operative position relative to the non-foldable member of said frame. As shown, said foldable frame member is adapted to rest when folded on shoulders formed by the upper ends of the stems 9; but this is an immaterial feature of; the carriage-supporting frame.

are normally drawn in one direction by the action of a spring contained within .asuitable drum and that themovement of the carriage is controlled by an escapement; but as the spring and the escapement mechanism do not form any part of the present invention I have not considered it necessary to illustrate or to describe said devices in detail.

40 designates a pivotal plate secured between the rear posts said plate having 42, in which are fitted the type-lever has a shoulthe plate 40, and said type-lever has a head 46, which is rovided with a series of type characters 47 The heads 46 of the type-levers are adapted to rest on a cushion 48, provided on a rest-bar 49, having legs 50 attached to the machineframe.

51 designates a series of key-levers each provided at its front end with a shank 52, hav- 53. Each key-lever has a short upstanding lug 54, provided with a pivotal sleeve 55, and the rear end of each lever has a notch 56, across which extends a pin 57 adapted to receive the hook 58 of a link 59, the upper end of said link being suitably connected to the shoulder 44 of the type-lever.

6O designates a series of pivotal rods on which are loosely hung the sleeves 55 of the key-levers.

The keys are held under tension by coiled springs 61, which lie below the banks of keylevers. Said springs are connected to crossrods 62, which are attached to supportingplates 63, the latter being slidable on the members 5 of the machine-frame. The plates are adjusted by manipulating the rods 64, which are loosely supported in the main. frame and have threaded engagement with the plate 63, whereby the tension of the springs may be increased or decreased to secure the desired tension on the key-levers.

The improved machine should be equipped with an inking mechanism, which is preferably carried by the carriage-supporting frame. Any suitable kind of inking device may be employed su ch, for example, as an inked ribbon adapted to be coiled on and uncoiled from suitable spools, said ribbon arranged to pass through a suitable guide on the carriagesupporting frame in order to lie adjacent to the roller-platen.

The operation of my invention will be read-- ily understood from the foregoing description, taken in connection with the drawings. The depression of one of the key-levers pushes on the link 59 to raise the corresponding typelever 43, and assuming that the carriage is in its normal lowered position (shown by Figs. 2 of the key-lever will strike through an inked ribbon against the paper confined on the platen, thus securing the desired impression. If it is desired to have the upper-case type strike through type-levers 43.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a type-writer, a foldable support for a platen-carriage having one of its members movable to, an abnormal position in overhanging relation to a keyboard.
