Abstract: 1707. Schimmel, F. Feb. 12,1908, [Convention date]. Type-bar making machines; single-type composinq and casting machines; matrices.-Apparatus for casting single types is combined with a type-bar making machine so that castings in one or other or both styles may be obtained by a single operator. The single types are cast as the line of matrices proceeds to distribution, and while the next line of matrices is being assembled. The application to a type-bar making machine of the kind described in Specification 14,156/05 is described, the magazines 4, 5, Fig. 7, containing matrices 6, of a nearly round form, which pass into a collector 3, when the keys are depressed, and are set up into line in a composing-frame and conveyed by a wheel 8 opposite a metal pot 9 where a type-bar is cast. A second frame replaces the filled frame at the composing position. The mechanism for casting type-bars may be dispensed with, the mechanism for setting up the matrices being combined with the apparatus for casting separate types, and hooks being provided for coupling and uncoupling the arms conveying the composing-frames. Distributing matrices; driving-mechanism; metal pots and pumps.-The line of matrices is further conveyed from the pot 9 to a position where the matrices are distributed by screws to their magazines, a separate type being cast from each matrix in turn. Fig. 13 shows the position of the various parts when a type is being cast. The pot carriage 11 is moved up to the mould 68, 69 by a cam on a shaft 14 and, during this movement, a lever 16 moves off a support 19 and, subject to the control of a cam, allows a spring 17 to operate the pump-plunger. The matrices passing from the composing-frame are lifted, one at a time, by a lever 24, and pass, under the action of screws 20, 21, along distributing- bars 22, Fig. 8. The first matrix, in passing, raises a lever 97, thus lifting a lever 95 and lowering the left-hand end of a rod 49 over a pin on a clutch control-lever 39. Driven from a shaft 31 are two shafts 34, 35, the former being connected through a clutch with a gear-wheel 44, and the latter with a gear-wheel 50 through a clutch which is controlled by a lever 43 connected with the rod 49. The toothed ring of the gear-wheel 44 is frictionally mounted. The first matrix passes along until opposite the mould, at which moment a cam device on the wheel 44 operates the clutch-lever 39, thus stopping the screws 20, 21 driven by the wheel 44, but at the same time moving the clutch-lever 43 to rotate a cam 53 driven by the wheel 50. The matrix is thus arrested while a cast is taken by the action of the cam 53; the further rotation of the wheel 50, however, operates the clutch-lever 43 to stop the cam 53 and again drive the wheel 44 for a further revolution of the distributing- screws. The shaft 31 may be thrown out of gear so as to stop the mechanism for casting separate types. Moulds; justifying type ; trimming type ; galley mechanism.-(1) A rod 55 operated by a lever 54 from the cam 53 actuates a lever 56, and thus causes a vice to advance and press the matrix up against the mould. The vice comprises a fixed part 57, Fig. 4, slidable to and from the mould, and a laterally-movable part 65 controlled by a spring and a cam 62 on a shaft bearing a pinion 61. The part 57 is shaped to correspond with the matrix. The vice and pot carriages are simultaneously advanced against the mould, and a rack on the pot carriage rotates the pinions 61 and clamps the part 65 of the vice upon the matrix. The distributing-bars 22 allow the slight advance of the matrix. (2) The mould comprises two blocks 68, 69 ; the block 69 only is movable up to and away from the matrix by a lever 67 connected with the link 55, while the block 68 is movable laterally against the action of a spring 73, Fig. 6, by a lever 72 on the same shaft as an arm 80, which is rocked by a pin on the movable pumpcarriage 11. The movement of the block 68 is limited by a projection on the movable side 65 of the vice, so that the mould cavity 75 may be equal in width to the matrix. A projection on the block 69 engages a recess in the fixed side of the vice during the casting-operation. (3) A slide, depressible by a lever 83, actuated by the cam 53, and provided with a knife-blade and a pad of leather or other soft material, moves downwards, before the mould blocks are separated, and shears off the jet from the base of the type. The block 69 then moves away from the matrix carrying with it the type; the slide descends again and, by means of the soft pad, causes the type to fall on to a table 114, Fig. 11. In re-ascending, the slide operates another slide which pushes the type broadways beneath a retaining - pawl against the edge of a plate carried by a slide 89, Fig. 8, which is thus moved against the action of a spring 92. The slide 89 is provided with a plate 99, which may be of different lengths according to the length of the line of types to be cast. When the lever 95 is depressed by the action of the first matrix on the lever 97, a pin 98 thereon passes under the plate 99 and prevents the lever from rising until the line is completed, when the rod 49 is lifted to throw the casting-mechanism out of action ; movement of the distributing-screws however continues. (4) The spacers, which are of the compressible type, are not carried along by the screws but fall immediately into their magazine. An empty space may thus be left between two matrices, and in this event the lever 97 will te lifted by the rear matrix to position II, Fig. 8, and a stepped slide 101 ascends so that the wider of the two steps acts on the member 74 of the mould-block 68 to cast a space of a certain width. After the last matrix in the line has passed the mould, the remaining space is filled up by casting spaces of smaller width, which takes place when the narrower step on the slide 101 is opposite the member 74. The last gap, if wider than the space produced by the narrower step, but narrower than a certain amount, is filled by a space cast when the position of the slide 101 is controlled by a pivoted hook 102 operated by a cam 106 on the slide 89. (5) The complete line is transferred from the table 114 to an adjustable galley 107, 110, Fig. 11, by the action of pins 112, 121 and a cam 118 on the arm B', B<2> or B<3> when it arrives at the distributing-position with a composing-frame. This action causes an arm 113 to press back the types already in the galley, and the table to tilt into position for delivering its contents.
