To all whom, it in/coy concern/.- 7

Be it known" that I, CHARLES. REYNOLDS KELLY, of Louisville, in the county of Jefferson and State of Kentucky, haveinvented certain new and useful Improvements in Type-VVriting-Machine Attachments; and I hereby declare that the following isa full,

will pull the cord attached to the device on the platen-carriage.

The invention consists in thenovel construction and combination of parts hereinafter described and claimed, and. illustrated in the accompanying drawings, in which Figure 1 is a plan view of a portion of a type-writing machine, showing the platenturning and carriage-returning devices applied thereto. Fig. 2 is an enlarged rear view of these devices. the platen-turnin g attachments. Fig.4 is a detailed view of the treadle attachment. Fig. 5 is a detail view of plate D. Fig. 6 is an end view of Fig. 4.

In the accompanying drawings I have illustrated the invention as applied to 'what is known as a Remington No. 2 type-writing machine, but do not restrict myself to its use in connection with such machine, as it can be readily adapted and applied to other makes or styles of type-writing machines.

My invention when applied to the Remington No. 2 embodies four attachments-to wit, first, a device attached to theplaten-turning lever;.second, a bell-crank device attached to the carriage; third, a guide-roller attached to the frame, and, fourth, a treadle or cor'dactuating device.

The platen carriageA is mounted, as usual, so as to be reciprocated horizontally, moving from right to left during the printing opera"- tions and being returned to the right-hand side of the machine at the beginning of each line.

Fig. 3 is a detailed view of The platen B is journaled in the carriage A, as usual, and provided with a ratchet b, engaged by a pawl c on an oscillating lever O, pivoted to the carriage,- and which lever is ordinarily manipulated by hand to turn the platen and to return the carriage to righthand position when desired.

In the Remington No.2 machines the platenturniug lever C is extended rearwardly, and to this extended portion of said lever I attach the first device, which comprises a plate D, having lips 03, to hook over the top of the lever, and a set-screw d, which can be screwed into the plate beneath the lever O, and its enlarged head binds against the side of lever C in advance of the pin 0, which is used on leverC as ordinarily constructed as an abutment for the spring a controlling dog 0. Thus the device can be readily and securely attached to lever G of any RemingtonsNo. 2 machine.

A rod D, connected to plate I), extends rearwardly above the rear bar of the carriage, in position to be engaged with a member of the second attachment. This attachment consists of a plate E, bent to fit upon the rear bar of the carriage and secured in position by a set-screw E. To this plate is hinged a double or bell-cranked rod E, which is shown standing at right angles to the platen, and on the shorter arm of said bell-crank is hinged or pivoted a link 1, having an eye f, transfixed by rod D, so that when the bell-crank is rocked and link f lowered lever C will be depressed and. the platen rotated. A spring E may be arranged to actuate crank F to normallyhold link f in uppermost position. The longer arm of bell-crank F is provided with aneye F, to which a cord G is attached, said cord passing to the right and over a pulley I on the third attachment and down to the treadle attachment.

The third attachment consists of a platestandard H, having its lower end provided with'inwardly-standing parallel flanges h 71., provided with inturned lugs h on their edges and adapted to embrace the right-hand lug M on the type-writer frame, in which one end of the carriage-guiding rod N is journaled, this lug existing on all N o. 2 Remington machines. The upper end of the standard H is bifurcated, as shown at I, and in this bifurcation the pulley I is journaled, as shown, so

as to sustain and guide the cord G. The cord passes from pulley I down to a sheave or drum J, on a shaft J, journaled in standards K on a casting K, upon which the treadle L is pivoted. The inner toe end of treadle L is connected to a cord j, fastened on a small drum or pulley j, fixed to shaft J. Consequently a slight movement of the treadle will be sufficient to impart a much greater movement to cord G, because of the difference in diameters of drums Jj.

Operation: The several attachments being in position the operator depresses the heel of the treadle, which slacks up cord j sufficiently to permit the carriage to move from right to left, as usual. Upon the completion of a line, or whenever the operator desires to return the carriage toright-hand position and space the paper, he depresses the toe of the treadle. This causes cord G to wind up on drum J, and the pull on cord G first rocks lever F, so as to pull down rod D, and thus through lever O and pawl 0 turn the platen on the carriage, and the continued pull on the cord moves the carriage to the right and holds it until the heel of treadle is depressed, whereupon the springs throw lever C and lever F back to normal position. Thereupon the operator proceeds with his writing without having to manipulate the platen or carriage by hand and with a little experience can soon operate the mechanism with certainty and skill, thus increasing his speed by saving the time ordinarily lost in manipulating the carriage by hand.

In order to lessen the shock or impact of carriage at end of its return stroke to the right, a bulfer-spring H is attached to the standard H and projects forwardly therefrom in position to be engaged by the carriage just as it reaches the end of its return stroke. A light spring-rod H is also attached to standard H and projects inwardly in position to engage the rack of the carriage-escapement and prevent the rack jumping out of engagement with the dogs on the rebound. A spring L may be arranged to rotate drums Jj backward, when the toe of treadle is released, thus avoiding the necessity of the operator depressing the heel of the treadle by foot.

I do not restrict myself to the specific constructions of the several attachments just as herein shown and described, asthe proportions and configuration thereof can be easily varied within the scope of my invention to adapt them to suit the particular machine to which the attachments are to be applied.

Having thus described my invention, the following claims summarize the features and combinations of parts for which I ask protection by patent:
