drawings.

This invention relates to type-writers, and particularly to that character of machines known as a bar-lock type-writer.

The invention has for an object to present an improved construction of shifting device, whereby the paper-carrying carriage is mounted upon an oscillating cradle, so as to be hifted beneath the type carried b v the typears.

A further objectof the invention is to provide means by which this cradle may be shifted or held in either of its adjusted positions and `by which the escapement mechanism therefore may accurately operate under all conditions.

Other objects and advantages of the invention will hereinafter appear in the following description, andthe novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure l represents a side elevation of a type-writer embodying this invention and having parts of the base broken l away. Eig. 2 is a detail perspective of the operating means for the escapement and ribbon mechanisms, and Fig. 3 is a similar view of the shifting-lever.

Like letters of reference indicate like parts throughout the several gures of the drawings.

`The letter A designates the base of a typewriting machine,which may loe of any desired construction or configuration and has mounted therein a series of key-bars A', )ivoted at any desired point-for instance, as at A2. Upon this base or frame A an oscillating cradle B is pivotally mounted at its opposite ends by means of the depending lug B and pivoting-apertures B2, while the upper face of this cradle is provided with any suitable means for permitting the reciprocation of the carriage C thereinfor instance, the raceways B3, carrying ball-bearings O and adapt- Serial No. 69,112. (No model.)

ed to cooperate with similar ways C2 upon the carriage. This carriage has mounted at the upper portion thereof the usual paperplaten G3, adapted to be rotated therein, and is provided at its lower portion with a feedrack C4, located in the saine vertical plane as the pivot B2 for the cradle and adapted to mesh with a pinion mounted upon suitable supports extending from thebase, said pinion being provided with an escapemen't-wheel D', adapted to cooperate with the pivotallymounted dog D2, carried upon a xed support. The carriage is provided with any suitable form of tension or spring mechanism for irnpartinga moving power to the same during the wrtin g operation. vFor the purpose of oscillating this cradle a shift-key E is secured thereto and projects forward to the keyboard of the machine, where it is provided with the usual finger-piece E', while the opposite end of this key-lever extends to the rear of the cradle, as at E2, and is there connected by a spring E3 to a fixed partof thebase, so that said spring is adapted to restore the cradle to its initial position after it has been oscillated or shifted by a depression of the shiftkey E. When it is desired to retain the cradle and its operating-bar in the forward shifted position with the spring under tension, the same may be accomplished by meansof the cam-lever F, which is pivotally mounted at F `upon the base of the machine and provided at E2 with a projection lying eccentric to its pivot, whereby a shifting of the lever depresses the key-bar E and holds the same in its shifted position to throw the cradle forward.

The ribbon-carrying arms G, which in this character of machine are adapted to have an oscillatory movement in each movement of the universal bail of the machine, are pivotally mounted at G' upon the oscillating cradle B and the end G2 thereof connected by means of a link G3 with the universal bail H, which lies beneath all of the key-bars of the machine, whereby adepression of either the key or the space bars will produce a downward movement upon the end G2 of the ribbon-arms G, thus throwing the upper end G5 thereof over the platen and carrying the ribbon beneath the type at the instant of contact with the paper upon the platen. A rock-arm IOO H is connected to the universal bail and also to the dog mechanism D2 for the purpose of oscillating this mechanism transversely of the escapement-wheel D at each downward movement of a type-key or space-bar. The rock-arm H is secured to the shaft D3, which is mounted to rotate in a fixed support, and has also secured thereto the oscillating dog mechanism D2. The free end of this arm is slotted to permit the necessary movement in the oscillation of the arm and reciprocation of the bail H. It will be understood that each of the type-keys is4 suitably connected by the usual ligaments with the type-bars I, and such details of construction have not been specifically illustrated in the present application.

The type-bars herein described are pivotally mounted in a segmental bearing K by means of screws K4, and this bearing is supported by a plate K from the standard A4.

In the operation of the invention it will be seen that adepression of the shift-key will rock the cradle forward, thereby bringing the carriage and platen to a position beneath a capital character upon the type,`if a small character be normally used when the cradle is in its initial position. This same movement of the shift-key places the spring E3 under tension, so as to restore the parts to their initial or normal position immediately upon the release of said key, while if it is desired to retain the key and cradle in a shifted position the same may be accomplished by a movement toward the left of the lever F. A depression of any of the typekeys causes a similar movement of the uni- Versal bail H, which operates the ribbon-shift beneath the type and feeding mechanism, as hereinbefore described.

It will be obvious that changes may be made in the details of construction and configuration of Ithe several parts and that the novel features herein described may be applied to other and dierent characters of type-writers from that illustrated without departing from the spirit of the invention as defined by the appended claims.
