INTERCHANGEABLE CARRIAGE FOR TYPE-WRITERS.

SPECIFICATION forming part of Letters Patent No. 793,069, dated June 27, 1905.

Application filed August 18, 1902. Serial No. 120,157.

To (1, 11:71.07), 7'2. max/ concern:

Be it known that we, JOHN J AY Hnnmns, residing at 210 lVestFourth street, New York, county of New York, and Ax'rnoxv A. HIE- BER, residing at 12%3 Putnam avenue, Brooklyn, county of Kings, State of New York, citi- Zens of the United States, have invented certain new and useful Improvements in Interchangeable Carriages for Type-"riters, fully described and represented in the following specification and theaccompanying drawings, fori'ning a part of the same.

The object of the present invention is to furnish a type-writing apparatus adapted not only to write upon an ordinary rotary platen, but also to write upon theleaves of books or other sheets of paper held upon a stationary flat platen. This object is accomplished by providing'two beds, one having a flat platen adapted to hold the paper stationary and to support the type mechanism movably and the other adapted to support the paper movably and to hold the type mechanism stationary, and also providing a type mechanism having a baseframe which is fitted interchangeably to similar supports upon the two beds, so that it may be used interchangeably with either. "here the bed has a stationary fiat platen, it is suited to support the leaf of a book as in other book type-writing machines, andit may also be used for writing upon flat sheets of paper larger than those which can be conveniently held by a rotary platen, and the letterspacing is secured by the bodily movements of the type mechanism, while the line-spacing is effected by a carriage supporting the same. lYhen the type mechanism is fitted to such bed, the paper is held stationary, as in similar type-writing machines, and the type mechanism moves beneath the lingers of the operator, and the position of the hands must be constantly changed to operate upon the i moving keys; but the interchangeability of l the type mechanism with the other bed and its platen enables the type mechanism to be held stationary when not writing in books and avoids such a requirement of the operator. Upon the other bed the type mechanism is held stationary over a movable carriage, and the movement of the keys is avoided, and the movable carriage, with its rotary feeding device, furnishes the means of moving the paper for line and letter spacing under the type mechanism. The type mechanism may be of any well-known or suitable character, and the means of holding itinterchangeably upon the two beds may be varied at pleasure, as the essential feature of the invention is atype-writing mechanism having one platen adapted to hold the paper stationary and having supports to hold the type mechanism movably, while the other bed has a platen adapted to hold the paper movably and has supports to hold the type mechanism stationary.

in the drawings illustrating the invention a type mechanism is shown of the class claimed in our application, Serial No. $5,810, filed February 4, 1901, in which the type-bars are arranged to strike downwardly through an open-bottom frame; but the type-bars and the means for operating them are omitted in the drawings, as they form no part of the present invention and would obscure the representation of the parts which are essential.

Figure 1 is a plan of a bed having a papersupporting carriage and platen movable upon tracks in the lower part and having above such carriage elevated supports to receive the base-frame of the type mechanism and hold it stationary. Fig. 2 is a front view of the same; Fig. 3, a rear view of the same; and Fig. 4:, a front elevation of thepaper-carriage and platen, upona larger scale, detached from the bed. Fig. 5 is a cross-section of the same, the section being adjacent to the letters A a) '11 at the left-hand end of Fig. l, with one of the boxes for the hinge-rail broken off to expose the guide-rolls which embrace such rail, and such box is shownseparately in Fig. 6. Fig. 7 is an edge view of the bed combined with a stationary platen for use in a book typewriter, the base-frame of the type mechanism being shown thereon; and Fig. 8 shows an end view of such base-frame detached from both of the beds. Fig. 8 shows the inner side of one of the boxes for the hinge-rail with the collar (Z having the tooth *0. Fig. 9 is a plan of the bed shown in Fig. 7, with a longitudinally movable carriage having a guide-rail. and a track-rail thereon. with the base-frame of the type mechanism fitted thereto. Figs-1O to 12 show an alternative construction.

a designates the base-frame of the type mechanism, having at the rear edge two posts 6, Fig. 2, carrying grooved guide-rolls c, which are fitted to a cylindrical rail (Z, which serves as a hinge-rail for turning the type mechanism upwardly to inspect the printing. In Fig. 5 dotted lines are extended upwardly from the base-frame a to indicate the arrangement of the type-bars 2f, the keys t, and the space-bar t To permit such upturning of the type mechanism, the hinge-rail may be held stationary and the grooved faces of the rolls slipped thereon or the rolls may be gripped firmly upon the hinge-rail and the ends of such rail journaled to turn as an axle. The latter construction isshown in the drawings, in which Figs. 1 to 5 show the base-frame of the type mechanism held stationary upon a bed having side bars A and cross-bars B. The upper parts of the bars A are provided with lugs a, which support the base-frame, and track-rails 2' are affixed to the lower part of the side bars A to support rollers it upon a paper-carriage g, which carries a 'rotary platen g movably beneath the type mechanism. The rear side of the carriage g is provided at opposite ends with boxes e to support the hinge-rail (Z. The rail is formed, as shown in Fig. 1, with collars (Z near each end to fit inside the boxes and prevent longitudinal movement; but the rail is detachable from the boxes, so that it may be removed from the bed, with the type mechanism, for use upon another bed, as described above. The hingerail is provided with teeth 1' to serve as a rack-bar, and the usual feed-pinion k and escapement-wheel Z are shown in Fig. 1, supported upon the base-frame a, so that when actuated in the usual manner by the keys of the type mechanism they cause the hinge-rail and the paper-carriage g (to which it is attached by the boxes 6) to move step by step beneath the type mechanism for letterspacing. The usual spring-drum m is shown in Fig. 1 attached to the bed A and connected by band at with the end of the carriage 9, so as to move it in the usual manner at each actuation of the spacing mechanism. The spring-drum is not shown in Fig. 5 for want of room upon the drawing, but is fully shown in Fig. 1. The carriage g is shown in Fig. l

with guide-rolls 0 at opposite sides of the rotary platen g and in Fig. 5 with small rolls 0 pressed upon the tops of the guide-rolls by springs 0 A knob 29 is connected with the guide-rolls 0 by gears 21. and the paper is fed across the surface of the platen step by step for line-spacing by turning the knob after writing each line. The side bars A of the bed are shown formed in Figs. 2, 3, and 5 with longitudinal slots A, through which a sheet of paper P can be inserted between the rolls 0 and 0 and shifted intermittingly for line-spacing, while the letter-spacing in the lines is effected by the usual movement of the carriage beneath the type mechanism upon the rails The base-frame a is shown provided upon the front edge with track-rolls q for use with a stationary carriage, and such rolls are utilized with the bed shown in Fig. 5 to hold the type mechanism stationary by their engagement with notches q in the side bar A, as shown in Figs. 2 and 5. With the type mechanism held stationary the hingerail (Z, which is attached to the carriage, moves longitudinally between the guide-rolls 0 when fed for letter-spacing; but such hinge-rail is so supported by the carriage 9 that the baseframe a and the type mechanism supported thereby may be turned around the axis of the rail (Z whenever desired to inspect the printing upon the paper beneath. During this operation the track-rolls (1 upon the base-frame are lifted from the notches q in the side bar A and are afterward replaced in such notches, which restores the type mechanism exactly to its former relation with the paper.

The apparatus thus far described holds the type mechanism stationary, so that the keys always retain the same positions under the fingers of the operator.

Figs. 7 and 9 show the base-frame of the type mechanism transferred to a line-spacing carriage having sides 0" and ends 7, fitted to a bed which is formed with sides .9 and end 8, adapted to rest upon a flat rectangular platen 3 to clamp thereon the leaf of a book or sheet of paper 5 which is to be inscribed. sheet is shown in Fig. 9 with a few words written thereon beneath the center of the baseframe a. The rear corners of the spacingcarriage 1' are provided with boxes 6, the same as those upon the paper carriage g (shown in the preceding figures) and arranged at the same distance apart as those upon the paper-carriage 9, so that the same or a simi-- lar hinge-rail (Z may be fitted thereto and sup- Such a I ITO port the rear edge of the base-frame a while its front edge is supported by the track-rolls q, resting upon the front edge r of the spacing-carriage, as shown in Figs. 7 and 9. A spring-drum m is shown upon one end of the spacing-carriage, and a hook n is shown upon the base-frame to engage the band n extended therefrom, so that the base-frame may be moved over the paper upon the platen s for letter-spacingwhen the escapement-wheel Z is operated by the keys. The right side 8 of the bed is shown provided with teeth, and a pinion or is shown journaled upon the spacingcarriage r and fitted thereto, which pinion would be actuated in the usual manner to shift the carriage upon the bed at suitable intervals for line-spacing. WVith this construc tion the line-spacing is effected by the movement of the spacing-carriage 1', and the letter-spacing is effected by the movement of the type mechanism upon such spacing-carriage, the base-frame [Z of the type mechanism being supported by the rails r and (Z, with the latter of which it may be turned up, as described above, to inspect the writing when desired.

The hinge-rail (Z is turned with the type mechanism by the engagement of the rackbar j with notches Zr (see Figs. 5 and 8) in the posts L, which carry the guide-rolls 0, and the type mechanism may thus be held in an operative position or raised to inspect the printing by stops applied to the hingerail (Z, and such a stop is shown in Fig. 8 for supporting the carriage to make any desired correction in the printing. When the carriage is turned upward to a position of equilibrium above the hinge-rail (Z, it is held in such position while inspecting the printing bya tooth '0 upon one of the collars (Z', which are rigidly fixed upon the shaft or hinge-rod (Z. The tooth e in such position engages a pin 1" upon one of the boxes 0. (See Fig. 8.) The construction of the boxes 6 is immaterial, as their essential function is that of a support for the guide-rail (Z. If a single hinge-rail be used in permanent connection with the guide-rolls 0, such rail must be connected detachably with the supports upon the two beds, so as to fit interchangeably upon both; but it is immaterial whether a single hinge-rail be used or corresponding guide-rails be provided upon the two beds and the guide-rollscconstructed to embrace them detachably.

in Figs. 1 to 9, inclusive, the hinge-rail (Z is shown removable from the boxes 6, each of the boxes having, as shown in Figs. 6 and 7, a hinged cap 6', pivoted upon the bearing a and provided with a latch e to lock it when secured over the bearing. WVhen unlatched, such removable cap may be thrown backwardly and the hinge-rail lifted from the bearing. If a single guide-rail be used in permanent connection with the guide-rolls c, as shown in Figs. 1 to 9, the hinge-rail must necessarily be connected in a detachable manner with the supports upon the two beds, so as to fit interchangeably upon both; but it is immaterial whether a single hinge-rail be used or corresponding guide-rails be provided upon the two beds and the guide-rolls 0 constructed to embrace them detaehably. Figs. 10 to 12, inclusive, show the latter construction, in which the guide-rolls 0 are separable, so that they may be detached from the hingerail and the type mechanism thus be used with either the stationary or the movable sheet of paper.

Fig. 10 shows in plan a bed A adapted to serve the same purpose as the stationary bed A B shown in Fig. 1, but having no front support for the base-frame a of the type mechanism, as the latter is designed to rest upon the moving carriage g. The bed A has rails Z to support the moving carriage. Posts 1 are shown projected upwardly from the rear edge of the base-frame a and the upper guideroll 0 pivoted thereon, while the lower guideroll is pivoted upon a stud 2 upon a block 3, which is movable vertically in a slot 4 in the base of the post. Levers 5 are hinged upon the posts 1 over the blocks 3, and each is formed in its lower end with an eccentric slot 6, fitted to the stud 2 in one of the boxes. The levers 5 are connected by a link 7, and one of them is provided with a handle by which both can be shifted at pleasure, the eccentric slots operating to raise and lower the blocks and the lower guide-rolls 0 when the lovers are moved back and forth. \Vhen the rolls (2 are separated by a suitable movement of the levers, as shown in Fig. 12, the baseframe and the type mechanism attached thereto can be removed from the hinge-rail (Z of one bed and transferred to the hinge-rail of another bed and the rolls engaged with such latter hinge-rail by reversing the position of the levers 5 to press the rolls together, as shown in Fig. 11.

Figs. 10 and 11 show ears 8 attached to the hinge-rail (Z in suitable positions to admit the upper guide-rolls c and to hold such rolls from longitudinal movement upon the rail. The ears 8 serve to hold the type mechanism stationary over the longitudinal moving carriage g (which is shown in Fig. 12, but omitted from Figs. 10 and 11) the same as the engagement of the rolls (1 with the notches q, shown in the side bar A in Figs. 2 and 5.

As stated above, no side bars like A are provided with the bed shown in Figs. 10 to 12, inclusive, as the base-frame a is supported wholly by the hinge-rail (Z and the moving carriage g.

WVith the construction shown in Figs. 1 to 9 the'type mechanism may be used with the movable platen or the stationary platen, by opening the boxes 0 and removing the type mechanism, with the hinge-rail (Z, from the supports which are connected with one of the platens, and fitting it to the supports connected with the other platen. \Vith the construction shown in Figs. 10 to 12, inclusive, the hinge-rails are secured permanently in their supports, and the type mechanism is transferred from one platen to the other when required by separating the rolls 0, as described, and detaching them from the hinge-rail of one bed and transferring them to the hinge-rail of the other bed. The apparatus is thus adapted to write either in stationary books or upon sheets of paper fed movably beneath the type.

From the above description, it will be seen that the invention embraces a type-writing apparatus which comprises a platen adapted to hold the paper stationary and having supports to hold the mechanism movably, and also a platen adapted to hold the paper movably with supports to hold the type mechanism stationary, and the type mechanism having means to engage the said supports interchangeably.
