Abstract: 16,967. Gestetner, D. Aug. 12. Addressing-machines - A machine of the kind described in Specifications No. 4966, A.D. 1905, No. 26,427, A.D. 1906, and No. 24,880, A.D. 1907, in which the printing is effected by means of a reciprocating platen and pad between which is fed a frame carrying a stencil and ink-pad, is constructed with (1) a hand-operated lever pivoted to a second lever, the first lever being capable of moving with, or at right-angles to, the second lever, to actuate the platen and to feed the stencil frames respectively, (2) a slide for moving the stencil-frames from the magazine into printing position and then into a receiver, and (3) a receiver formed of fixed and movable parts which enable the stencil-frames to be returned readily to the magazine. As shown in Figs. 2 and 3, the actuating-lever a is pivoted to a lever c, on the axle d of which is fixed a double crank-lever n provided with rollers m, which actuate a platen i, by means of a link j and lever k, and a pressure pad carriedby a frame p by means of a lever r. The levers a, c are constrained to move together by means of guides e on the machine frame until the end of the stroke of the lever c, and then the lever a may be moved in a direction at right-angles to the first movement to remove a stencil-frame and feed a fresh one. More than one printing may be effected from one stencil. The magazine is constructed with a rear plate u provided with side webs v, a front plate w, and a base formed of webs x. The stencil-frames are fed from the magazine by means of a slide 12, Fig. 5, actuated from the lever a by means of a link 13 and lever 14, which is connected to the lever a by a rod 16 having a ball joint at each end. The slide 12 is provided with a table 17, which supports the frames in the magazine, while a pusher 19 on the side of an opening 18 pushes a frame through the opening 18 on to fixed supports 20 corresponding to the printing position. On the return of the slide 12, the used frame is fed by a second pusher 19 through an opening 21 into a receiver. The receiver is formed of a fixed part, consisting of a bottom 1, and a back-plate with vertical end webs, and a removable part formed of two vertical angleplates 2, Figs. 3 and 10, each forming part of one end and of the front of the receiver ; the plates 2 are connected by spring bars 3, shaped as shown in Fig. 10, and are fitted with wires &c. 5, which form the bottom of the removable part. The plates 2 are fitted with ribs 4 shaped to fit in the usual notches of different form in the frames. The two parts of the receiver are connected by spring-controlled latches 6 connected by pivoted links. The upper ends of the plates 2 are splayed outwards to facilitate the descent of the frames, and, when the plates 2 are in the receiving position, they are opened out against the action of the spring bars 3 by inclines 9 on the bottom 1 and inclines on the upper latches 6. When the removable part of the receiver is withdrawn with the frames, the spring-bars 3 cause the frames to be gripped. The frames are transferred to the magazine, and are lowered with the carrier outside the magazine. The sides 2 are pressed outwards to release the frame and to allow the carrier to be withdrawn laterally with the frames deposited in the magazine. The machine is provided with the usual adjustable fence 24 carried by a bar 25, and also with springs 23 which retain the envelopes in a pile, and with a stop which acts as a buffer for the lever 14.
