Fig. 3 is a spacingdogs 18. Any other suitable means may be provided for supporting, guiding, and releasing the spacing-rack, or the dogs may be mounted on the carriage and the rack upon the frame of the machine in a well-known manner.

The guide-rail may be secured at each end in forwardly-extending arms of standards 22 23, which are fastened to the top plate and connected by a long horizontal bar 24 in rear of the guide-rail, and about midway of the bar 24 a third forwardly-extending arm 26 may be arranged so as to furnish additional support for the guide-rail. The guide-rail may be supported in any other suitable manner, and so long as it is laterally motionless it is immaterial to my invention whether it moves endwise or rotates in its bearings or not.

The platen-shifter may be hinged directly upon the guide-rail and may consist of two end disks or working portions 30 31 (which are eccentric to the guide-rail) and an intermediate cut-away portion 32, Fig. 3. As a preferred means for turning the'shifter about the shaft-axis a series of longitudinally-extending teeth 33 are out upon the under side of the body or cut-away portion 32 thereof,

Figs. 1 and 2, and a pinion 34 is arranged in mesh therewith, the pinion being operated by a finger-key 35 through a lever 36, which is pivoted between its ends at 37 to the side wall of the machine-base and connected at its rear end by means of a vertically-arranged thrust-rod 40 to the free end of a crank-arm 41, which is secured upon a horizontal shaft 42, extending parallel with the guide-rail 20, to a point about midway of the machine where the pinion 34 is secured thereon, and suitably mounted in brackets 38 39, secured to the top plate.

A suitable rectangular platen-frame 46 47 48, in which is supported the usual cylindrical platen 53, may be provided with rearwardly-extending hinge arms or ears 50 51, perforated so as to engage the eccentric disks 3O 31, so that the platen-frame is partly supported upon the shifter and so that when the shifter turns upon the rail-axis the platenframe is caused to move transversely to the line of writing.

For returning the parts to normal position a spiral spring may be arranged upon the shaft 42, one end being fastened to the top plate and the other end secured to the shaft by means of a tension-adjusting collar 56.

If desired, adjustable stops 61 may be arranged upon the bracket 38 for limiting the movement in either direction of the pinion, and consequently of the shifter and the platen.

The platen-shifter and the ears 5O 51 of the platen-frame are preferably confined between the arms 16 17 of the rack-bar frame,to which the carriage-propelling power is preferably applied, a cord 62 being secured at one end to an ear 63, projecting rearwardly from the rack, and at the other end to the usual springdrum 64, Fig. 4.

The platen-frame when swung up may be partly supported by a roll 65, which is mount ed upon the free end of an arm 66, projecting upwardly from about midway of the rear bar 45 of the platen-frame and which runs upon the bar or rail 24.

In operation when the finger-key 35 is depressed the rear end of key-lever 36 rises and by means of link 40 swings up arm 41, thereby rocking shaft 42 and the pinion 34 thereon, so that the platen-shifter in mesh with the pinion is caused to turn upon the rail 20 and by means of its eccentric construction draws the platen-frame and platen rearwardly. The positions of the parts when the shift-key is depressed are shown in full lines at Fig. 2. The normal positions of the shiftkey, eccentric, and platen are indicated by dotted lines. The long teeth 33 upon the shifter enable the platen to be shifted at all positions in its travel. Any wear to which the gear-teeth may be subjected, due to the sliding action thereof, will not perceptibly affect the rigidity of the platen,since the transverse movement of the platen-frame is much less than the peripheral movement of the teeth 33.

It will be observed that the platen-frame when swung up turns upon the eccentrics and remains positively connected to the shifter, such movement of the platen-frame tending to hold the shifter more firmly in normal position, thus avoiding the erratic movements of the platen-frame heretofore experienced by reason of the disconnection of the platenframe from the shift-rail. The stops for limiting the transverse movements of the platen are preferably arranged upon the framework of the machine instead of upon the shifter or carriage, thus obviating friction between the pinion and the shifter as the latter slides along, such as would occur if a stop were to be placed upon the carriage to limit the movement of the shifter, and hence of the fingerkey 36, inasmuch as in such a case the pressure of the finger of the operator would be communicated to the stop through the pinion and the shifter during the lengthwise movements of the latter. To the same end the returning-spring is also arranged upon a nontraveling portion of the machine.

So long as the key-actuated platen-shifter rides along a laterally-motionless guide-rail it is immaterial to my invention, considered in .its broad features, whether or not the shifter is supported directly upon the rail or upon some portion of the traveling mechanism or works upon the eccentric principle or is provided with gear-teeth or has a hinge action, as it may vary widely in construction and arrangement without deviating from the invention, considered in its broader features.

Ball-bearing h'mge.ln the modification illustrated at Fig. 6 a ball-bearing hinge is provided. between the shifter and the platenframe. The eccentric disks are provided with outturned cone-faces 70, and the hinge-arms are cupped at 71, the balls 72 being disposed between cup and cone in a manner common in bicycle construction. If desired, one of the arms 51 may be made adjustable lengthwise of the rear bar of the platen-frame, so as to secure a nice fit of the hinge and take up subsequent wear, and to this end the arm 51 is provided with one or two slotted ears 73, secured to bar 4:5 by screws 74, the slots permitting the required adjustment. Other suitable ball-bearing construction and adjustment may be employed.

Traveling bcZZ-bcctring.As illustrated at Figs. 9 and 11, the platen-shifter. may be of tubular construction, and balls may be arranged about the guiderail and confined within the tube, so as to travel endwise along the guide-rail and also around the rail, thus securing easy longitudinal and turning movements of the shifter, which is designated as 83 and fits closely over the balls. To hold the balls in position, a cage 81 may be employed, preferably tubular and provided at each end with one or more circular series of perforations 82, within each of which is confined a ball, and also with an internal ring 85 for supporting it upon the guiderail. The eccentric disks may be provided with inwardly'projecting rims 8% to slip upon and secure to the ends of tube 83, and the perforations in the disks should be larger than the guide-rail.

Carriage-releasa-At Figs. 9 and 11 the rack-frame isillustrated as provided with the usual forwardly-projecting finger-piece 8e. An upwardly-extending integrai finger-piece 85 is also provided to be used when the platenframe is swung up, being so arranged as to be readily drawn forward by the hand that lifts the platen-frame, thereby releasing the rack from the spacing-dogs.

Roller-track, Figs. 2, 6, and 7 .The broad ened front roll of the platenframe rides upon a long antifriction-roller track 91, extending parallel with the platen and provided with any suitable stationary suppo'rt,such as a bar 92, secured upon posts 93, rising from the top plate. The roller 91 rolls to and fro as the platen shifts, and to keep it at all times parallel with the platen each end thereof may be provided with gear-teeth 94, meshing with stationary racks 95, secured at each end of bar 92, the rack being provided with a guard portion 96 to prevent displacement of the roller. The roller may be capped at each end, as at 97, to prevent end wise displacement.

A modified construction for keeping the roller parallel is illustrated at Fig. 8, a rockshaft 100 being journaled in the standards 93 and provided at its ends with upwardly-extending slotted arms 101, which engage pivoi s or nipples 102, formed upon the ends of the roller. It is not essential, however, that any means be provided for keeping the roller 91 parallel with the platen.

So far as my platen-shifter is concerned any other suitable support may be provided for the opposite portion of the platen-frame,

and the roller-track is likewise adapted for use in connection with other shifting means.

Other portions of my invention may be used separately-as, for instance, illustrated in the construction at Fig. 10, in which the ball-bearing tube 83 is rigidly secured to a non-shifting platen-frame, securing a rigid, easy-running, and durable construction, besides permitting the platen-frame to swing up for inspection of the writing.

Numerous other variations in detail construct-ion may be made within the scope of the invention, and although certain claims herein cover preferred specific constructions I do not wish to be considered as being limited thereto as far as the broader features of my invention are concerned.

By the term shifter, wherever used in the specification or claims, I mean a device which forms a portion of acarriage and is arranged between a platen-frame and a latererally-motionless guide-rail and which is adapted to cause transverse movements of said-platen-frame relatively to said guiderail and which, further, is connected to a key Whose position relatively to the keyboard does not vary at the letter-spacing movements of the machine. Preferably the platenframe is guided upon the rail by means of the shifter. In carrying out this feature of my invention I prefer to hinge the shifter directly upon the guide-rail, so that the guiderail is the axis of the hinge; but it is not essential in adapting the invention to other machines that the guide-rail be arranged concentrically with the shifter-hinge, as the shifter may have anysnitable hinge, so long as it is enabled to turn upon said hinge to cause a transverse movement of the platen and so long as the shifter is provided with suitable means for enabling it to ride or travel endwise along the laterally-motionless guide-rail. It is not essential that the shifter be given a transverse movement by means of a hinge construction. Many portions of my invention are suitable for machines in which the paper remains stationary while the types are arranged upon a step-by-step-moving frame, and I consider such a type-carrying frame as the equivalent of the platen-frame referred to herein.

It will be observed that I have connected a finger-key to means which are pivoted upon the frame of the machine and directly engage a platen-frame shifter, so as to operate the same at all points in the longitudinal or step-by-step travel thereof, said shifter being adapted to travel along a laterally-motionless guide-rail and said platen-frame being preferably hinged to the shifter, whereby it is enabled to shift transversely and also to swing up to exhibit the writing, whether in its normal or shifted position, that the bar 24 and roller 65 limit the upward movement of the platen-frame, and that a letter-spacing rack or rack-frame is constructed to ride along said rail, together with said shifter and said platen- ICC IIO

frame. It will further be noted that the shifter preferably comprises an eccentric or a pair of eccentrics, the periphery whereof serves as the platen-frame hinge, upon which the latter is both shifted and turned up, the eccentrics being key-operated and rigidly united and hinged directly upon the guiderail, and that the platen-frame is provided with eyes or rings 50 51, which operate as straps upon the eccentrics and which surround the guide-rail, so that the platen-frame swings about the guide-rail. It will also be seen that I provide a spring-driven letterspacing rack or rack-frame which engages or is carried upon the guide'rail and is also preferably provided with an independent support, as 21, and which is adapted to move or carry the shifter and platen-frame in letter-space direction, and that preferably the eccentric which operates the platen-frame is confined between the arms of the rack or rack-frame. It will also be seen that as an independent front support for the platenframe I have provided an antifriction cylindrical track, which is adapted to tumor roll crosswise of its length during the transverse movements ofthe platen-frame, that preferably said track rolls upon or over a plane surface or surfaces, and that the turning or rolling motion of the track is caused by the pressure or weight of the platen-frame thereon.
