Abstract: 12,362. Pinel, J. March 1, [date applied for under Patents Act, 1901]. Monotype and like machines. - Relates to a strip-controlled type casting and setting machine capable of casting two or more of the characters at once. Specification No. 15,668, A.D. 1902, is referred to. In the machine shown in Figs. 1 and 2, there are two matrix carriers 68 having angular movement for character selection a n d ongitudinal movement for fount selection, and co-operating with a movable double mould. The strip has twelve lines of perforations, and is advanced two permutations at a time, and co-operates with two sets of selector needles 36 on levers 37. Thestrip is shown as winding off a drum 13 on to a drum 14 ; the winding may be effected by means of an endless band of elastic material. Six of the levers 37 in each set are for character selection, and are connected to ad justable spring plates 45 co-operating with a pallet 49 on an oscillating shaft 50, for the actuation of perforated selecting-bars 53 for permutation levers 54, serving to arrest the angular movement of the corresponding matrix carrier. Five of the levers 37 in each set are for fount selection, and are connected to three-armed levers 63, the upper arm of each of which actuates a bolt 65, Fig. 15, for arresting the longitudinal movement of the corresponding matrix carrier. The remaining lever 37 in each set is for space casting. The matrix carriers 68 are each provided with six founts of matrixes 67, retained by rods 70 and disposed between partitions reserved for the casting of spaces or blanks. Each carrier is screwed upon a hollow shaft 73, sliding on a solid shaft 74 but rotating therewith, the sliding movement being effected by means of three-armed levers 78 arrested by the bolts 65. The shafts 74 are driven from the main shaft through intermediate shafts provided with stops co-operating with the levers 54. Register of the matrices with the mould is ensured by the engagement of teeth 96 on the carriers with grooves 119, Fig. 56, in the upper parts 100, 100' of the mould. The mould comprises a movable sup-. port 98, Fig. 56, with the upper plates 100, 100<1>, cheek-plates 103, 103', and jet pieces 105. Movable and interchangeable blades 101, 102, Figs. 48 and 56, determine the mould cavities. Ledges 107 on the parts 100, 103' effect the formation of a bevelled edge, and ribs on the parts 101<1>, 103 effect the formation of the nick for hand-setting. The support 98 is urged forward against stops by a spring, and is moved rearwards by a cam-actuated lever. There may be several moulds for different depths of character, and means for throwing one or other into gear. Each matrix is provided on its lateral face with a small steel plate, which serves to actuate a bell-crank lever 126, Figs. 48 and 56, and adjust the blades 101, 102 for thickness of character, through an intermediate lever 128 having the centre of oscillation adjustable. For casting spaces, the blade 101 is arrested by a pivoted stop 130, actuated on the forward movement of the mould by contact with a lug on a slide connected with the spacecasting lever 37. The mould is cooled by circulation of air or water. A collector 104, Fig. 2, serves to close the mould during the casting operation, and afterwards receives sliding movement for removing the cast characters in succession to an elevator 137, Fig. 72, the characters being ejectedby the corresponding blades. Projections are provided on, the collector 104 for severing and expelling the jets. The metal pot 170, Fig. 21, is fitted with a piston 175, adapted to be held up against the action of a spring 177 by a spring-controlled fork 189. Two tubes 194, movable with the mould, conduct the metal to the mould, and carry a bar 193 for co-operation with a lever 191 on the fork 189, to release the piston 175. Each tube 194 contains a needle fixed to the bar 193 and adapted to obstruct the mouth of the tube, and the bar 193 has sufficient play in the tubes for the withdrawal of the needles from the mouths. Metal for maintaining the supply in the pot 170 is contained in a cylinder 202, carried by an adjustable lever 198. The elevator 137, Fig. 72, carries the type into a. guide-clip 158 on the composing-stick 207, a ' layer-on' 155 being forced aside for the passage of the type. The 'layer-on' is afterwards returned behind the type and receives an angular movement for transfer of the type along the guide-clip into the composing-stick. In the composing-stick is a slider connected by a band to an adjustable index plate 215, Fig. 2, which, on the completion of a line, abuts against an arm of a lever operating a clutch, whereby the line is pushed over into the galley 227 ; there is a locking-device in connexion with the pushers and the sliding clutch member. Leads may be supplied from a galley above the galley 227, by the vertically movable line-retaining plate, which is provided with a recess to receive the lead. In order to prevent pieing, adhesive, preferably alcoholic solution of resin, is applied to the types in the galley, between the lines, and the types are maintained at a temperature of about 100‹ C. ; or the line fed to the galley is maintained at a temperature of 160‹-170‹ C., and enters the galley through a passage of slightly diminishing breadth, causing adhesion.
