TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 575,147, dated January 12, 1897.

Application filed January 7, 1896. Serial No. 574,639. (No model.)`

To ctZZ whom it may concern:

Be it known that we, LEE S. BURRIDGE and NEWMAN R. MARSHMAN, residents of the city, county, and State of New York. have invented certain new and useful Improvements in Type-W'riting Machines, of which the following is a specitication.

Our invention relates to type-writing machines, and has 'reference more especially to improvements upon the type-writing machine for which we filed an application for Letters Patent, Serial No. 567,608, November l, 1895.

The object of our invention is to provide a simple and etlicient type-writing machine wherein a sheet may be employed as an inker and may be automatically and continuously fed by the operation of the machine proper so as to present a different surface to a printing-character after an operation of each of such printing-characters. V

Ourinvention consists in the special matters hereinafter set forth and claimed, and will be explained with reference to the accompanying drawings, in which- Figure 1 is a plan view of a type-writer embodying one form of our improvements. Fig. 2 is an enlarged sectional view thereof, the section being taken on line 2 2 of Fig. l. Fig. 3 is a perspective view of the machine with the carriage raised and the inker-carrier swung on its pivot in order to more clearly show the said inker and inker-carrier. In this view some of th-e parts are omitted in order that the inker and inker-carrier may be shown clearly.

Referring particularly to the drawings, wherein portions of a type-writing machine of the Remington type are illustrated, A is the main body or frame of the type-writer, uponwhich are carried the usual back rod a and shifting rod a', upon which the carriage B travels, the carriage being hinged upon the back rod in the usual manner. The carriage B also carries the usual impression-roller or paper-platen C and paper-roller D.

The impression-roller is rotated in any usual manner by means of a pawl c, which is carried upon the usual operating-lever E, which is pivotally hung at c and extends downward to form the usual handle F.

Projecting from the carriage B are the usual recessed lugs b2, which persons skilled in the art will recollect have heretofore been the studs l), projecting from the lugs b', and i serve to supporta supporting bracket or table G, which in the present instance is shown as with flanges g at the ends.

Seated in slots` in the flanges g and retained .by the brackets h is a rock-shaft j, which carries arms 7o, upon one of which a toothed segment Z is carried, a spring 253 tending to pull said arms and segment in a downward direction.

Carried by each of the arms 7c is an inkerengaging device, shown in the present instance as consisting of a claw m.

The toothed segment or segmental rack Z is located adjacent to a bracket H, which rises from the carriage B, and is provided with a shaft n, upon which a ratchet-wheel 0 and a mutilated pinion p, connected therewith, are mounted. The mutilated pinion 1J engages with the segmental rack Z, a click q, which is spring-impelled, serving to prevent a reverse motion of the ratchet and pinion.

An arm I is pivoted to the bracket by one end and carries a pawl r, which is springpressed and engages in the teeth of the ratchet 0. A rod J depends from the arm I and has a toe s, which extends beneath the lever E.

Brackets K depend from the socket b'. In these brackets is pivoted a frame or inkercarrier comprising bentwire sections t u, which enter the eyes of the rods K, and the wire section fv, which forms the front of the inker-carrier, the rods utbeing joined thereto by means of ears c w. The horizontal portions of these ears bear upon the shifting rod and project over the same to a considerable extent, so as to allow the necessary backward movement of the shifting bar when it is shifted to allow of upper-case characters being printed, the ears at the same time allowing the passage and free movement of theguides L of the roller-shifter which embraces the shifting rod when the carriage and inkercarrier are IOO down, as shown in Fig. 2, which represents the parts shifted to print upper-case characters. Each wire tu is surrounded by a spiral spring t" a', each of which terminates in a hook or engaging device t2 u2.

A plate M is carried upon the frame of the inker-carrier and is provided with ears y, between which a rod .e extends.

O is the inker, which is shown as of sheet form, and is engaged at its forward end by the hooks 2 u2 and at its rear end by the claws m, the said inker passing under and behind the rod or guide .2' and being kept taut by the springs t' u.

Vhen the carriage is down, as shown in Fig. 2, the machine is in position to print or write, any usual printing agent, as N, being employed.

It will be observed that although we have shown the inker-carrier as attached to and moving with the carriage in its travel from end to end of the machine, yet nevertheless the Ycarriage may be raised without raising theinker-carrier with it. The inker-carrier is, however,` shown in the present instance as capable of being swung on its own pivot independently of the carriage. By this means the inker-carrier can, when desired, be swung on its pivot from over the type-well to give access to the types for cleaning and other purposes.

The operation of our device is as follows: Supposing the parts to be in the position shown in Fig. 2, the type-writer is manipulated to write in the usual manner, the printing agent striking the inker and pressing it against the paper which is carried on the impression-roller or platen C. When the end of the line has been reached, the handle-operating lever F is manipulated in the usual manner to release the rear rack (not shown) from its cooperating part and to permit the carriage kto be slid back along its guides to start anew line. By the same operation the impressioirroller is stepped around to shift the paper to `the next line, and the lever E, coming against the toe s of the rod J, draws down upon the said rod, thereby swinging the leverl on its pivot and moving the joined wheels o p around one step by means of the pawl The movement of the pinion p has the effect of swinging the toothed segment l, with which it meshes, thereby pulling on the inker O against the tension of Aits springs t2 u2 and drawing it back a short distance to present a new portion of the inker to the printing characters after each line is written. This operation vis repeated each time the impressionroller Cis shifted to start a new line, and thus as the machine continues to be operated the inker is drawn back gradually as the arms k are ,swung ontheir pivot. Presently, however', the pinionfp willhave been rotated far enough to lbring the mutilated part p thereof opposite l the segmental rack and to disengage the teeth of the pinion from those of the segmental rack. Thereupon the segmental rack, being no longer engaged with the pinion, will, through the medium of the springs t', u', and t3, be swung downward, the springs t' u also serving to throw the inker into its extreme forward position, which is shown in Figs. l and 3. Further revolution of the wheel 0 will rengage the mutilated pinion p with the segmental rack, and the operations will be repeated.

It will thus be observed that by our invention the inker is automatically fed longitudinally or in the direction of the feed of the carriage and is also automatically fed at right angles to the feed of the carriage, so as to automatically and continuously present a different portion of the inker after each impression of a printing-character.

While our invention has been illustrated as combined with certain portions of a typewriting machine of the Remington Y type and as being applicable to such a machine without in any way changing the construction of such machines as at present existing, we would have it distinctly understood that we do not limit ourselves to the use of our improvements to a type-writing machine of any particular type.

It will be obvious to those skilled in the art that the apparatus which We have shown for carrying out our invention is susceptible of many Variations, dependent upon the circumstances of use.

What we claim, and desire to secure by Letters Patent, isy l. The combination with a mechanical writing-machine, of an inking device comprising van inker and means for automatically'moving the printing portion of the inker in ,one direction in `one plane by the travel of, thefearriage, and means for moving the printing portion of the inker Aat right angles thereto in the same plane as `before by a rotation of the impression-cylinder, and restoring means for automatically bringing the inker to the initial position. 4
