TYPE-WRITER.-

SPECIFICATION forming part of Letters Patent No. 722,291, dated March 10, 1903. Application filed June 2,1902. Serial No. 109,966. (No model.)

To all 11/72/0112, it may concern:

Beitknown that I, ARTHUR O. FERGUSON, a citizen of the United States, residing at Brooklyn, in the county of Kings, State of New York, have invented certain new and useful Improvements in Type-Writers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a type-writer, and particularly to a machine in which the typebar is shiftable in relation to the platen.

The invention has for an object to present a construction of type-writer in which the keys are flexibly connected to the type-bars for the purpose of operating the same; also, to provide improved means for vertically shifting the carrier for the type'bars relative to the platen supported by the paper-carriage.

A further object of the invention is to provide a type-Writer having a platen supported above a vertically-disposed type-bar carrier, together with means for shifting said carrier, and a flexible connection from the carrier to a depressible key.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings, Figure l is a vertical crosssection through a type-Writer embodying my invention. Fig. 2 is a vertical section on the line 2 2 of Fig. 1. Fig. 3 is a detail vertical section illustrating the shifting means for the type-bar carrier, and Fig. 4 is a plan of the inking-roll.

Like letters of reference refer to like parts in the several figures of the drawings.

The letter A designates the base of the machine, which is provided at its front portion with vertical standards A, adapted to support the keyboard, and at its rear with a track or way A in which the paper-carriage B is adapted to reciprocate, the latter being provided with standards B, supporting at their upper portions a platen B and also an inking-roll B the latter being supported by an arm 13*, extending above the platen from one standard and to which the inking-roll B is pivotally mounted at the end B by means of the angular hanger B. This roll is slightly at one side of the point of contact of the type with the platen, so that the type by first contacting with the roll forces it away therefrom and inks the type in its passage toward the platen. The platen may be of any ordinary construction, and also the sliding carriage and way. This carriage is also provided with a rack-bar B supported upon one face thereof and cooperating with an escapement mechanism O,which is pivoted at the point C to oscillate in a vertical plane and normally held in the position shown in Fig. 1 by means of a spring 0 This escapement mechanism is also adapted to oscillate in a horizontal plane upon the central pivot C for the purpose of disengaging the dogs from the rack, and this horizontal movement is limited by the stop-pin C The escapement mechanism is provided with a forwardly-extending lever or arm 0 which terminates at the front of the keyboard in a key 0 Between the keyboard and the paper-carriage a supporting-arm D is secured to the base and extends over the escapement mechanism. This frame is provided with a series of vertical guide-rods D, upon which the segmental type-bar carrier D is slidingly mounted. This carrier D is disposed in a vertical plane at one side of the platen and below the axis thereof, so that the type-bars E, carried thereby, lie in different horizontal planes completely away from the platen, so as to permit an unobstructed View of the writing at all times. Each of these type-bars is provided with a type E, having a plurality of characters thereon, and in order to print either of these characters it is necessary to shift the carrier in a vertical plane. For the purpose of vertically shifting the type-bar carrier any desired form of key and connector may be used; but Fig. 3 illustrates a preferred form which permits a movement of the type-bar carrier independent of all other parts of the machine. This shifting is accomplished by means of lugs D extending from the carrier and resting upon cams or eccentrics D carried by a shaft D which is provided with a crank-arm I), connected with the keyboard of the type-writer by any suitable means-for instance, a flexible connector D extending over a pulley D to the lower end D of a shift-key F. This key is normally held in its raised position, as shown in Fig. 3, by means of a spring F, located between the upper plate G and the lower plate G, forming the support for the keyboard. A pin F bears upon the upper end of the spring, which is compressed in the 5 downward movement of the key to restore the key, while the crank-arm D and cams D actuated thereby, are restored to their initial position by means of a spring D extending from the arm D to a standard B. Each of 10 the type-bars is pivoted at E Within the alining slots E formed in one face of the type-bar carrier D and the type-bar is also provided with an angular end portion E, from which a connector II extends to the keys I,

mounted in the keyboard. At the opposite side of the carrier D from the type-bars a supporting-rod is mounted upon brackets E and to this rod a restoring-spring E is secured at one end and attached at its opposite end to each type-bar. Between the connector H and the pivot of the bar a lateral extension E is formed upon the type-bar and by engagement with the frame of the carrier E limits the downward movement of the bar.

The connector H is shown as of a flexible character and passes over a pulley H, supported from the under face of the plate G and connected at H to the lower end of the key I. This key is normally held in an elevated position by means of a spring I bearing at one end upon the surface of the plate G and at its opposite end upon a projection 1 carried by the key. Beneath all of the keys a univeral bail is provided, which is composed of a plate J, extending from oppositelydisposed levers J, which levers are pivoted at J at the rear of the machine, while the forward edge of the plate and levers is supported by a spring J carried by the stand- 0 ard A, so that the depression of anykey carries downward the plates J and also the extended arm C of the escapement mechanwhen the key therefor is depressed.

between the type-bar carrier and the keyism, which lies directly beneath this plate their; which movement the spring 3 is placed under tension and immediately restores the plate to this elevated position when pressure is removed from the key.

In the operation of the invention it will be seen that the depression of the key transmits motion through the connector to the type-bar lying beneath the platen, thus raising this bar first into contact with the inking-roll and then with the paper carried upon the platen. This downward movement of the key also depresses the plate of the universal bail below governing the escapement mechanism, and when pressure is relieved from the key the escapement feeds the carriage forward and I the type-baris restored to its normal horizonoo tal position by the restoring-spring therefor. When t is desired to shift the tyne-bars so as to print other characters thereon, the shiftkey is depressed and through the connection with the crank-arm operates the cams beneath the typebar carrier, raising this carrier to such a distance as to bring the proper char- It will be noted that at this time the connection board is not materially disturbed, nor does the relation thereof to the key lie in such manner as to affect the regular operation of the machine for either of the characters upon the type. It is also noted that the keys as herein mounted permit a direct downward movement thereof and transmit this movement through the flexible connector to the type-bars, so as to secure the most advantageous stroke of the type against the platen and permit a shifting of the type-bar carrier relative to the platen.

It will be obvious that changes may be made in the details of construction and configuration without departing from the spirit of the invention as defined by the appended claims.
