ATTACHMENT FOR TYPE-WRITING MACHINES.

SPECIFICATION forming part of Letters IEatent No. 473,236, dated April 19, 1892.

Application filed July 6, 1891. y Serial No. 398,472. (No model.)

To all whom, it may-concern.

Be it known that I, CHARLES J. REED, a citizen of the United States, residing at Orange, county of Essex, and State of New Jersey, have made a new and useful Invention in Attachments for Type-Writing Machines, of which the following is a specification.

My invention has for its object the positive movement of the paper-carriage and its attached parts in both directions, and also the forward advancement of the paper line by line through the agency of an extraneous source of power controlled bythe carriage either at the ends of its journey or at intermediate points, as may be desired. In order` to bring about these movements in the aforesaid parts of an ordinary type-writer, I make use of an electric or other motor so connected electrically and mechanically with the carriage-frame that it will cause the carriage to be automatically returned to its starting-- electrical energy for supplying said electric motor with electricity, and electrical and mechanical connections between the movable part of the motor and the type-writer mechanism, whereby the above-named results may be attained.

Referring to the drawing in detail, F F represent the end supports of the carriage-frame, and A the paper-sustaining. cylinder, B and D being the paper-feed rolls journaled in the frame, and R the impelling-rack, T being a gear-wheel impelled by a spring-operated drum (not shown) andv meshing with the rack R, the carriage and its attached parts having lateral motion to and fro upon anti-friction rollers p 1o, journaled in the stationary frame F2, supported by the table G.

N is an escapement-Wheel upon the same shaft with a gear-Wheel W meshing with the rack R.

- K and K are escapem ent-pallets, the former actuated by a universal arm V each time one of the keys is depressed, they not being shown inY the -present instance.

L is a bell-crank lever pivotally secured to the end support E and adapted to impart a `rotary motion to the paper-feed rolls B D step by step through the agency of a ratchetwheel, as shown, each time that pressure is brought upon the free end of said lever, in order to force the paper-carriage to the right.

All of the parts so far described are found in the well-known form of Hammond typewriter, and are simply illustrated here for the purpose of showing the application of myimprovement thereto, the several parts of which I will now proceed to describe.

E is a sliding bar supported in the stationary frame F2 and lying in a plane parallel with the rack R, said bar E being provided with a fixed lug s at one end and an adjustable lug s3 at or nearthe other end, m being y a pin or lug carried by the rack R orattached to some portion of the movable carriageframe.

t is an electrical conducting-spring lying in the path of the outer end of the sliding bar E,which is also of conducting material and electrically connected with the conducting portion of the frame F2, the spring t and said frame F2 being in turn connected by a conductor w, through a switch Sand contact-stops s s2, with a battery B A, electric motor M', and a clutch electro-magnet M, the connection with the magnet M being through stationary brush-contacts b b and ring-contacts e e', carried by the armature-shaft a, which in turn carries a magnetic clutch C, attached to a loose-running pulley P, to which is secured a cord c, passing over a fixed pulley P', located over the carriage-frame, the other end of the IOO upon the paper is completed, at which time the pin or lug m will be carried into frictional Contact with the stop or lug .51 on the sliding bar E, thus forcing it ultimately into electrical contact with the springt, thereby closing a derived circuit from the battery B A by wires w, through stationary brush l), conductingring e, magnet M, conducting-ring c', stationary brush b', wire w, switch S, contact s', spring t, sliding 'oar E, frame F2, through contact s2, back to battery, the motor M being in a permanently-closed circuit, as shown. The closing of this derived circuit therefore causes the clutclrmagnet M to bring the pnlley I into such frictional relation with the armature-shaft a, which is continuously rotated, that the cord c, which is wound upon it, thereby imparts to the bell-crank lever L a tilting motion and to the paper-carriage and other attached parts a motion in a reverse direction to that indicated by the arrow, thus simultaneouslyplacing the spring in the drum connected to the gear-wheel T under additional stress and winding it up for further ac tion when the paper-carriage is again started on its direct journey. As this reverse motion to the paper-carriage and platen is continued the lug or pin m ultimately strikes the adjustable stop s3, thereby automatically imparting to the bar E a sliding motion in the reverse direction to that originally given to it, thus breaking the circuit between said bar and the spring t and demagnetizing the clutch, so that the shaft a is disconnected from thepulleyP and the bell-crank lever L permitted under stress of an actuating-spring (not shown) to impart to the paper-feeding rolls B and D a forward motion, and hence to the paper between them an advance motion of one line or space. This operation continues automatically as the operator advances the paper-carriage line by line, so that all that is required in the manipulation of the machine is to operate the key-levers in the desired sequence, the mechanism thus described performing the functions of moving the carriage and feeding the paper forward line by line.

It will be understood, of course, that the motor M is running continuously under the iniuence ofthe current from the battery B A, connected to the binding-posts B B2, and that the clutch-magnet M is only brought into operation at the ends of the lines, as already described, or at intermediate points, if desired, through the agency of the switch S by turn'- ing it in the direction ot the arrow into conneetion with the contact S2 and reversing this clutches now in general use may be utilized tor this purpose. Nor do I limit myself to such an electrical and mechanical arrangement of parts that any specific class of typewriter is required, as it is obvious that these attachments may be applied to any welllcnown forniof type-writer in general use; out I have selected one specific fo1m--viz., the llaminonddas best adapted to illustrate the application of my invention.

Having th ns described my invention, whatl claim, and desire to secure by Letters Patent of the United States, is-

l. A type-writer having a motor for impelling the paper-carriage in one direction and an additional motor for impelling it in the reverse direction and simultaneously storing up energy in the first-named motor,with mechanical and electrical connections, substantially as described.

2. A type-writer having a paper-carriage provided with a source of power for advancing it, in combination with a source of power having electrical and mechanical connections, whereby the carriage is automatically restored to normal position at the end of each line and the first-named source of power re plenished, substantially as described.

A typewriter having a source of power for advancing its paper-carriage, in combination with a second source of power having mechanical and electrical connections for restoring the paper-carriage and replenishing the first-named source of power, substantially as described.

A type-writer having a source of power for advancing its paper-carriage, in combination with a second source of power having mechanical and electrical connections for restoring the carriage to normal position at the end of its journey and additional electrical connections for bringing the second source of power into service at intermediate points, substantially as described.

5. A type-writer having a paper-carriage provided with a source of power for impelling it, in combination with an electric motor having mechanical and electrical connections with the carriage for restoring it to normal position and reviving the source of power at any point of its journey, substantially as described.

6. A type-writer having a source of power adapted to advance the paper-carriage, in combination with a second source ot' power, as an electric motor, adapted to return the carriage and revive the first-named source of power, substantially as described.

7. A type-writer having its paper-carriage operatively connected to a source of power, as a spring, a motor having mechanical and electrical connections with the carriage, and a circuit-closing device operatively connected with the motor and the carriage, whereby the latter is advanced by the spring and returned by the motor, substantially as described.

8. A type-writer having its paper-carriage IIO adapted to return it at any point of its journey, substantially as described.

10. A type-Writer having the paper-carnage connected to a source of power adapted to propel it in one direction and an electric m0- tor provided with clutch mechanism and electrical and mechanical connections, whereby the carriage may be restored to normal position and the power replenished, substantially as described.
