GEORGE BECKER, OF NEW' YORK, N. Y., ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE POPE MANUFACTURING COMPANY, OF BOSTON, MASSACHUSETTS.

TYPE-WRITING MACHINE.

SPECIFICATION forming part Of Letters Patent No. 455,299, dated July 7, 1891.

Application filed April 5, 1883. Serial No. 269,705. (No model.)

To all whom it may concern:

Be it known that I, GEORGE BECKER, of N ew York, county and State of New York, have invented an Improvement in Type-Triting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention has for its object to construct a type-writing machine which may be cheaply made, easily operated, and adapted to print both capitals and small letters;

In accordance with this invention the index-plate, free to slide horizontally upon a guide-rod, is moved forward thereon step by step by a suitable feeding device, the typeplate being reciprocated horizontally parallel with the index-plate by the finger or hand of the operator. The printing-lever is depressed by an oscillating bar pivoted to the framework, the bar being operated by a lever pivoted, preferably, at the left-hand side of the machine, the feeding device being adapted to be operated by said oscillating bar. Suitable centering and spacing devices are provided, and also means for rotating the upper feeding-roll step by step to present a new line beneath the printing-lever to be printed. Suitable means are also provided for returning the index-plate to its normal position or starting-point. The horizontally-moving index-plate is so held as to occupy two positions relatively to the index-plate to present two different sets of characters beneath the printing-lever, all as will be hereinafter more fully described. Suitable inking-pads are provided for supplying ink to the type-plate.

Figure 1 shows in plan view atype-writing machine embodying this invention; Fig. 2, a left-hand end View of the machine shown in Fig. 1; Fig. 3, a cross-secti0n of a machine shown in Fig. 1,taken on the dotted line at :r; Fig. 4, a detail of the device for rotating intermittingly the upper feeding-roll to be described; Fig. 5, a detail of the feeding device to be described; and Fig. 6, a detail of the inking-pads.

The main frame-work comprises the side pieces 2 3, joined by the rods or bars 4 5 6 7, and the frame carrying the printing devices is pivoted to the main frame, said pivoted frame being composed of the side bars 8 9, joined by the rods 10 11 12. The index-plate a, is secured to the frame or, having brackets (t at the rear side, by which it is mounted to slide horizontally upon the rod 11, and also having brackets a at the front side, by which it is mounted to slide horizontally upon the rod 10, the rods 10 and 11 thus serving as guide-rods. The type-plate b isv secured to a carrier I), placed beneath the index-plate a, said carrier 17 being recessed to receive a rock-shaft 5 mounted to rock in the frame a near the front of the machine. The typeplate Z) has on its under side two sets of characters arranged parallel with each'other, (see Fig. 3,) so that as the type-plate b and carrier Z) are moved toward and from the operator upon the rock-shaft 11 one or the other set of characters will be presented beneath the printing-lever. The type-plate carrier Z) has secured to it a finger-piece 17 which projects upwardly and has attached to it a pointer Z2 which moves over the index-plate. It will thus be seenthat the type-plate may be moved horizontally and also toward and from the operator at will.

The printing-lever c, pivoted to a block 0 has extended through it loosely near its forward end apin 0 held by a spring 0 secured .to the upper side of the said lever. The rear end of the printing-lever c is cut away or bent to present a curved arm 0 which bears against an oscillating bar or rod, made preferably by attaching to a single rod, as 12, two blocks 0, one near each end, each block receiving the ends of two rods 34, one at each side of the rod 12, as best shown in Figs. 1

and 3. Asthe rod 12 is oscillated in one direction, it acts upon the arm 0 of the printing-lever c and depresses the forward end of the printing-lever c, causing the pin 0 to act upon the type-plate, and as the oscillating bar is returned to its normal position, the lever 0 is restored to its normal position by a spring 15.

The forward end of the leverchas a chiselpointed projection c which, when the lever is depressed, enters between one or another of a series of teeth 16, at the rear edge of the type-plate carrier 1) to assist in accurately positioning the said carrier to place the type or character next to be used in correct position. The oscillating rod 12 has secured to it at one end a bent arm (Z, (see Fig. 2), the free or outer end of which is acted upon by one end of a lever d, which extends forward, as at (F, to the frontof the machine, the depression of the lever (Z lifting the lever (l and oscillating the rod 12 to depress the printinglever. Another lever e is pivoted to the main frame-work at the left-hand end of the machine and connected with the lever (Z by a pin 17, which passes through a slot 18 in the lever e. The lever 01 can thus be operated without moving the lever e, as the pin 17 follows in the slot 18; but by depressing the lever a, the lever (Z will be partially depressed for purposes hereinafter to be described. The outer right-hand end of the oscillating rod 12 has secured to it a cam-block f. A toothed rack or bar f having teeth at its upper side is mounted so as to be moved horizontally in side plates 8 9 of the frame. The toothed rack f is normally drawn toward the left-hand end of the machine by a springf and at its opposite end the said bar carries a friction-roll f, which bears upon the inclined or cam face of the block f, and consequently as the said cam-block is lifted by the oscillating rod 12 by depressing the lever (1 the toothed bar f will be moved against the action of the springf toward the right, a distance equal to one tooth of the bar. A toothed arm or detent f is secured to a spring-controlled or yielding arm f, pivoted to the block 0, the other end of the said detent engaging the teeth of the bar f, and as the said bar is moved ahead or toward the right one tooth the block 0 and the frame to which it is attached, together with the index-plate, are drawn forward one step in order that the next letter maybe printed in its proper place. By depressing the let er e the rod 12 will be oscillated only enough to move the frame forward withoutpressin g the type upon the paper. WVhen the toothed rack is reeiprocated horizontally a sufficient number of times to complete a line, or at any other time desired, as when spacing, the pivoted arm f may be pressed in toward the block 0, disengaging the toothed arm f from the toothed rack, thereby enabling the index-plate to be returned to its normal position.

Two rotatable inking pads or surfaces 2 are pivoted to the frame to which the indexplate is attached, directly beneath the typeplate, so that as the type-plate is moved horizontally it rubs over the said surfaces and the printing-lever will depress the type-plate between the said inking-surl'aces and press the type down upon the cylindrical-surfaced rod 7. The paper is fed forward over the paperfeeding roll 9 and beneath the plate g, bearing down upon said roll, and the roll is provided at one end with a series of recesses 26, (see Fig. 4: one or another of which receives the end of the bent arm having a slot g,

through which passes a pin upon which the bent arm is pivoted, the slot servmg as a loose connection permitting the arm to be moved sufficiently to 26 of thefeeding-roll. The bent arm g upon being depressed will move the roller 9 ahead to present a new line beneath the printinglever.

If it is desired to look at the printing the pivoted frame 8 9 1O 11 12, carryingtl e printiug device and index-plate, may be lifted, as shown in dotted lines, Fig. 2.

In a type-writing machine, the horizontally-movable index-plate, combin ed with the independent type-plate, its recessed carrier, and the rock-shaft therefor, said carrier be ing movable longitudinally and also toward and from the front of the machine upon said rock-shaft, two sets of printing characters arranged in parallel lines on the type-plate and movable with the carrier, positioning-teeth on said carrier, and the printing-lever having a projection to engage said teeth 1 n either position of the carrier, substantially as de scribed.
