TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 358,469, dated March 1, 1887.

Application filed December 19, 1884. Serial o. 150,708. (No model.)

To all whom it may concern.-

Be it known that I, NATHAN Gama Moons, of Peoria, in the county of Peoria, in the State of Illinois, have invented an Improved Type- Writer; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawings, making a part of this specification, in which like letters of reference refer to like parts, and in which v Figure 2. represents a plan view of the same; Fig. 1, a side elevation; Figs. 3, 4, 5, 6, 7, 8, 9, and 10, views of various details of the mechanism.

This invention is in the line of typewriters in which a longitudinally-progressive and laterally-oscillatory roller is adapted by such movements to press a sheet of paper wrapped thereon against types held in the periphery of a disk, a lever serving not only to turn said disk and thereby bring the desired letter in juxtaposition to said roller, but also, by its downward impression, to oscillate said roller against the type or letter.-

The object of this invention is the effecting of several improvements in such a type-writer, of which the following are the chief: First, simpler and more effective mechanism for longitudinally shifting the roller and its carriage; second, means for inking the types; and, third, automatic arrangements for revolving the roller.

In the drawings, R is the roller for carrying the paper; 0, the carriage supporting said roller and adapted to travel longitudinally. O is a frame pivoted to said carriage and con taining the bearings of said roller.

The types project radially from th e type-disk D, which is adapted'to be revolved in a horizontal plane by means of the lever Ii,pivoted at one end to the lug L, projecting from said disk and near its center, to the shaft S. The crown D and the letter-circle D, being necessarily fixed in position, are secured to or formed as a part of the plate F, as shown in Fig. 9, which plate is supported by the frame F. The type-disk D, being made annular and having its inner diameter fit looselyabout the crown D, rests upon the projecting edge of the plate F, and can be revolved thereupon, with said crown as a center. The shaft S is loosely held to permit longitudinal movement, and connects at its lower end with an angle-iron, S, by which its vertical motion transmits through the connecting-rod S the required oscillation to the frame 0 and its contained roller R.

The crown D is sharply serrated, and the projection P of the lever L is made terminally V-shaped, that, when said lever is pressed down over any particular letter, the sloping sides of said projection and the serration thereat shall cause, when the projection reaches the bottom of the serration, the lever to be exactly over the letter, although at first it may not have been placed quite true. Then the projection P is rigidly fastened to the lever, the slight movement which said contact of the serration and projection gives to the disk D, coming at the same time with the forward oscillation of the roller B, causes the impression of the type against the paper to be somewhat blurred. To prevent this, I adapt the projection P to be vertically movable in the lever L,

having it pressed downwardly by means of the spring P. The neck I of the projection P is square, to prevent its turning in the lever, and a cross-pin keeps it from dropping out from its opening in the lever.

The frame 0 is pivoted at O to the carriage O, and is provided with the buffers O to stop the backward oscillation of the frame 0 and its contained roller R. Said backward oscillation is given to the frame 0 by the spiral spring S on the connecting-rod S between the bearing S and the collar S". To receive a part of the shock of the forward throw of the roller It as it comes against the types T, I have constructed the buffers B, adjustably secured at the ends of the arms B". In front of each buffer Bis a spring, B, by which the force of the impact of said roller is broken- Said arms B To pull the carriage O in one di-" about the wheel J. The wheel J is revolved by means of aspring coiled therein, (not shown in the drawings,) the tension of which is adjusted by means of the ratchet-wheel J and the pawl J The key-stem J enables the spring to be wound up. This wheel J is continually pulling the carriage 0 forward. To control this pull and cause the said carriage to progress only the width of aletter after each printing-stroke, Ihave devised the following construction: A rack-bar, E, is secured to the carriage G by pivots or hinges E. A springcatch, E", keeps the rack-bar down in place. Beneath said rack-bar and meshing therewith is a gear-wheel, G, fast on the shaft G. Fast on the other end of said shaft is an escapewheel, G". The anchor-escapement H, pivoted at its center to suitable supports projecting up from the base-plate or board \V, prevents said escapewheel G from revolving. The pawl H", pivoted in a slot in the shaft S, is pressed within said slot when said shaft is pushed downward. Vhen, however,said shaft is raised,this pawlpushes against the upward end of the anchor-escapement H, releases its other end from contact with the eseape-wheel G, and permits said wheel to revolve for the space of one tooth. This distance is arranged to be the required space between each two letters printed by the writer.

To give the space between each two words and wherever else desired, I supply a lever H", by which, on pressing upon the button H thereof, the escapement H is made to release the wheel G \Vith each distinct movement of said lever the wheel G" moves one tooth and the carriage O is shifted accordingly.

My device for inking each type just previously to the impact thereagainst of the paperwrapped roller B, is as follows: The arm K pivoted at 11*, to a lug projecting from below the plate F carries at its outer extremity a small inking-roller, K, held to said arm by slender springs K. This arm K is thrown upwardly with each downward stroke of the lever L and the shaft S by the impact against the end K of said arm of the friction-roller K held by the collar K fast on said shaft S. With the downward stroke of the lever L this arm K is carried up,theinking-roller K passes up against the type, which has just been turned thereto, suitably inking it, and is held up above the disk D, while the roller R comes forward against said type. Then as the pressure is removed from the lever Lsaid roller returns and the arm K falls, and the inking roller K therewith, to its original position. If the weight of said arm is not sufficient to replace it quickly, I design to furnish a suitable spring for aiding such movement.

In order to return the carriage to begin another line, the spring-eatch E is released from the rack-bar E, and the same is raised up out of mesh with the gear-wheel G. The carriage O can then be pushed back to its initial position without hinderance. XVhen thus replaced, the rack-bar E is lowered to again mesh with the gear-wheel G, the spring-catch E re-engages with the said bar, and the carriage is all ready for its new line. Before beginning the new lineit is necessary, however, to turn the roller B a distance equal to the desired space between the lines. To do this automatically I have devised the following device:

The lever M, pivoted to the axis of the roller R, has a pawl, M, engaging with the ratchet-wheel R of said roller. Held in bearings N, projecting from the way-bars O, is a triangular plate, N. A spring, N, pressing against the lug N" of said triangular plate, serves to keep the same in the position shown in Fig. 2. Vhen the lever M travels along with the carriage in the working-passage, said plate N is simply pushed out of the way by the end of said lever; but when the carriage is returned to begin a new line the lever M slides up on the sloping edge of the plate N, is raised, and the pawl of the lever M caused to engage with a new notch in the ratchet-wheel B. As the pawl passes the plateN and drops down beyond the same, being pulled by the spring M the roller R is given the desired lineal change. In place of said plate N, I sometimes use the modification thereof shown in Fig. 7.

Instead of swinging horizontally, my new plate N is adapted by the horizontal axis N" to swing in a vertical plane parallel with the roller R. Thelower half of this plate N", being weighted at N, as the paper-roller R is returned for a new line, the lever M comes in contact with the edge thereof, and is of course raised in order to pass it. This raising of the lever M, as previously described, enables its pawl to engage with a new ratchet-tooth of the ratchet-wheel B. To enable the spring M to give a quick pull to said lever, and thereby a partial turn of the roller, the plate N has a quadrant cut therefrom at N, which out also enables the said plate to be revolved by the lever when traveling in the opposite direction and to-release said lever without raising the same.

At the end of the lever L, opposite to the presser-button L, is the fingerL, extending through a slot in the lug L, and terminating just over the edge of the type-disk D. The object ofthis finger is to enable the types to be adjusted relative to the crown and letter-circle. If, when the projection Pis pressed into a serration of the crown D, a type is not exactly beneath the end of said finger, it is at once evident that a correction is needed. To permit of this adjustment, the type disk D is composed of three thin annular disks, D D and D. D are the outer disks, to the upper of which the lug L is rigidly attached, while D, the inner disk, is the type-disk proper. Said disk D, I usually form of wood or hard rubber and divide its periphery into the radial notches D, equal in number to the characters which I design the type-writer to have. By employing a suitable number of screws, D", to clamp together these disks D, D and D,

and having the screw-holes in the disk D elongated at right angles to the radii thereat, the said disk D can be evidently revolved somewhat relatively to the disks D and hence adjusted relative to the lever L and to the letter-circle. Figs. 8 and 9 show this arrangement of the type-disk. The disk D, Imake slightly thinner than the types, so that the disks D can grip the types sufficiently hard to hold them securely in place.

I am aware that prior to my invention typewriters have been constructed in which are many of the details shown in the drawings and described in the specification of this application; hence I do not claim them broadly; but

What I claim as my invention, and for which I desire Letters Patent, is as follows, to wit:
