Abstract: 18,658. BollÚ, C., [Schimmel, F.]. Sept. 5. [Patent of Addition to No. 14,156, A.D. 1905.] Type-bar making machines.-Relates to machines of the kind described in Specification No. 14,156, A.D. 1905. The carrier-wheel which supports the composing-frames is replaced by three arms, each of which supports a composing - frame and is mounted loosely and independently of the other arms on a shaft b. The arms are so connected that, during the movement of one arm through an angle of 180 degrees from setting to casting position, the second and third arms are moved through an angle of 90 degrees from casting to distributing, and from distributing to setting position respectively. The arms 1, 2, 3, Fig. 2, are each formed near the shaft b with a segment to which is pivoted a lever 5 adapted to bear against a pin 7 on the segment of the adjacent arm. As the arm 1 moves down towards the casting position, the arm 3 is raised by the lever 5 into the vertical or distributing position. The lever 5 is then withdrawn by a curved slot formed in a fixed bracket 11 which engages a pin on the lever, after which the arm 1 completes its movement into the casting position. The arm 2 is simultaneously moved down into the setting position by the lever 5 carried by the arm 3. The arms are guided by a fixed circular rim 12 the upper half of which is of smaller diameter than the lower half so that a step is formed at each side. The steps are engaged by a tooth 13 on a slide 14 which is movable radially on each of the arms 1, 2, 3. A second tooth 15 on each arm 14 is adapted to engage a constantly-rotating internallytoothed wheel z. By means of a hand-lever 4, the tooth 13 of the arm which is in the setting position is withdrawn from the step and the tooth 15 are moved into engagement with the wheel z. The arm then makes half a revolution after which the tooth 13 slips off the larger part of the rim 12 and the tooth 15 is withdrawn from the wheel z. Each composing-frame c is pivoted to its carrier-arm and, during setting, occupies the open position shown in Fig. 5. As the arm moves downwards, the frame is closed by striking a fixed stop 19. In the distributing position, the frame is opened by a lever 20 which strikes a roller on the machine frame. The end of the composing-frame is closed by a plate h fixed on the carrier arm. During setting, the matrices are retained in the frame by a pawl 28 on the lever 20. The spiral spring which actuates the piston of the composing-frame is replaced by helical springs. The compression of the spacers is effected in known manner by two screwed bushes one of which is toothed and is connected by gearing with a rack carried by the casting-pot. The matrices are clamped against the mould by eccentrics also operated by the casting- pot. The distributing-rail is horizontal and parallel with the axis of the composing-frame, the matrices being fed along it by screw spindles in known manner. The india-rubber wheels which rotate the matrices in the collector are replaced by brass rollers which are loose on their shafts and press the matrices against a rotating ring mounted on ball bearings. The spacers consist each of two nearlycircular plates 38, Fig. 10, formed with slits 39, the parts of the plates between the slits being bent inward and riveted together. The spacers are assembled and distributed in the same manner as the matrices. When two magazines are employed, the change from one to the other is effected by means of a hand-lever 46, Fig. 12, the shaft of which is geared to a shaft 45. The magazine g<1> is moved vertically by an arm 52 on the shaft 45 and a connecting-rod 51. The magazine g<2> is moved laterally by a lever and a grooved cam on the shaft 45. The magazine in use is held down on the collector e by a nose 61 on a slide 60 which is connected with a slide 59 operated by a second hand-lever. The matrices are retained in the magazine during the change by a pivoted flap 55 operated by an arm 56, lever 57, and spring 58. When a magazine is raised, the lower part of the flap is turned into the magazine by the spring. When a magazine is seated on the collector, a lever 62 carried by the slide 60 is pushed under the end of the lever 57 which is thereby raised, the flap 55 being turned into the position shown on the magazine g<2>. The lowest matrices are thus released and drop upon the matrix-supporting blades 53, the matrices above being held back by the upper part of the flap 55. When a matrix is selected by the depression of a key, the second row of matrices in the magazine is liberated to permit a matrix to replace the selected one. This is effected by the movement of the matrixsupporting blade 53 which causes a shaft 69 to rotate and the lever 62 to be pulled down so that the flap 55 is rocked by the spring 58. The uniform descent of heavy and light matrices is ensured by levers 64, which project over and push down the lowest matrices in the magazine. The levers 64 are mounted on the slide 59 so that they are withdrawn to permit of a change of magazine.
