Abstract: 28,767. Boult, A. J., [Osborn, H. C., and Gammeter, H. C.]. Dec. 29. Rotary machines ; type, setting and distributing ; type. - Relates to machines of the kind described in Specification No. 5368, A.D. 1903, for printing circulars &c. having the appearance of type-written documents. Fig. 1 shows a front elevation of the machine, which comprises a printing - cylinder B and a type-storing cylinder A, the types being composed from the cylinder A into the cylinder B, and distributed back from B to A. The types, Fig. 13, are provided with side grooves x for engaging longitudinal ribs or rails on the cylinders A, B. Between the two cylinders in the stationary frame member z<1> is a transfer channel z<6> through which the types pass from one cylinder to the other. The cylinder B is turned intermittently, when composing or distributing, to bring its channels successively into register with the channel z<6> ; while the cylinder A is turned, by the aid of an index mechanism, to bring the row of types having the required character into register with the channel z<6>. The cylinder A may be turned by the crank handle a<5>, its position being indicated by a fixed index R, and a pointer S' on a block S sliding between the rails H', H<2>. To the block is attached a cable S<2> passing round guide-pulleys S<3>, S' to a pulley on the end of the cylinder, to which its end is attached. The other end of the cable passes round a guide-pulley,S<5> to a spring-drum winding- device T. The movements of the cylinder A are limited by a stop-pin a<9> thereon engaging a pivoted stop-arm U having a limited movement so that the drum may be moved to the same position in either direction. The cylinder B may be rotated continuously by its crank F for printing, but when composing &c. it may be rotated a distance between two type-channels by means of a hand-wheel w<3> rotating with a pinion w<2> in gear with the wheel b<3> on the cylinder. The wheel w<3> is formed with a series of conical depressions engaged by the end of a spring pin to locate the feed movements. When it is desired to print, the pinion w<2> and wheel w<3> are lifted out of action by means of a lever W on which they are mounted. The positioned line of type in either cylinder is pushed along towards the other cylinder by slides h, h<1> movable longitudinally and vertically between the bars H, H<1>. The slide h is provided with ratchet teeth on its underside adapted to engage teeth on a sliding block J having a pawl for engaging behind the line of types in the cylinder B. Similarly, the slide h<1> has ratchet teeth adapted to engage teeth on follower blocks G in the channels of the cylinder A. The slides are moved downwards and forwards so as to engage and feed the types and then upwards and backwards to clear the blocks J, G. They are moved longitudinally by lugs on a ring k, and the up-and-down movements are effected by blocks capable of limited longitudinal movement only, and formed with inclined slots engaging inclined projections on the upper edges of the slides h, h<1>. The ring k is held between discs k' on a shaft K, and has a spring connection with such shaft so that it may be arrested while the shaft continues to move. The shaft K may be moved in either direction, to operate either slide h, h<1>, by means of gearing k<9> and a shaft L provided with two finger-keys l<2>, P. To limit the advance of the line to one type at a time, a fork N is provided, having a backward-and-forward and also an up-and-down movement, so that its teeth engage between the types in the channel z<6>. The types are bevelled at x<1>, Fig. 13, to permit of the teeth n engaging between them. The movement of the fork N along the channel z<6> is limited to the width of a type. The shank n' of the fork N is connected to a lever n' operated by a cam k<11> on the shaft K, to raise and lower the fork N. On the shaft L is a sleeve P having a spring arm p forked to engage and move the shank n' of the fork N. The shaft L is returned to position by the spring Q, which surrounds the sleeve P and has its projecting ends embracing a pin p<4> on the arm p, and also engaging opposite sides of the frame member z<1>. The outer end of the shaft L, which is of square or similar section, engages in the tubular shank l<1> of the keys l<2>, l<3>. In order to ensure the accurate position of the cylinder A when the key l<2> or l<3> is operated, a lever Y is provided, having a bevelled pin v' for engaging a notched ring on the cylinder. The arm v of the lever V engages a slot in the collar V<1>, thereby preventing the operation of the keys until the cylinder is positioned. For convenience of insertion of types by hand into the printing-cylinder, one channel of the cylinder A is left empty and aligned openings are formed in the frame standards z, z<1>. The contour of the channels is preserved in these openings by the edges y<1> of split tubes Y, Figs. 2 and 14. By turning the tube Y, by means of the pin y, the opening may be closed. The composed types in the cylinder B are inked during printing by a ribbon passed round the cylinder and wound on two spools D, D' in the recess b<2> in the cylinder. The spools are readily removable, being held by springs d<7> with their opposite ends in engagement with studs journalled in the end member b<5> of the drum. On each of these studs is a ratchet-wheel, and either of these wheels may be operated, to feed the ribbon, by a pawl on a radial rod formed on the inner end with a strap surrounding a fixed eccentric through which the shaft b of the drum passes. The outer end of the pawl rod is guided by a slotted pivoted arm which may be rocked by hand, or automatically by the tension of the ribbon, to reverse the direction of feed of the ribbon, The paper is pressed against the cylinder B by the impression cylinder E.
