Abstract: 2470. Imray, O., [Fowler Composing and Type Setting Co.]. Feb. 5. Type; type, setting.- The types and soft compressible spaces are cast and delivered into the upper ends of the magazine channels of a composing-mechanism, from which they are ejected singly, and are collected into lines, justified, and placed into a galley. Fig. 3 shows a vertical section of one form of machine, and Figs. 14, 23, and 24 show parts of the assembling and justifying mechanisms. A metal pot 2 is pivoted on the framing 1 at 44, so that its mouth 23 may swing into contact with, and away from, the moulds 11 carried by a rectangular-wheel or plate 10 mounted on a shaft 9. The pivots 44 of the pot may be on adjustable slides 45. The pot 2 has a compartment for soft metal and one or more for type metal, and each compartment 4 has a pump piston 49 and a separate discharge passage and mouth 23. The soft-metal passage communicates with mould cavities 11 for casting the compressible spaces, and those of the type-metal compartments communicate with groups of mould cavities 11 for casting the types. The type-metal compartments, when two or more are used, each communicate with a group of mould cavities, and their operation is controlled so as to cast the groups at intervals varying with the frequency with which they are required in the composing-mechanism. The wheel 10 has two sets of mould cavities 11, and is driven intermittently by a bevel-wheel 42 and a partial bevelwheel on the shaft 34, through a half revolution, so as to bring one set of mould cavities opposite the mouth of the metal pot, and the other set opposite the ejecting-mechanism. The matrices are in cavities in bars 15, having arms 16 by which they are pivoted on the sides of the mould wheel 10. Each matrix bar 15 has a projecting pin at one end which, as the wheel 10 revolves, comes into contact with fixed pins 19, 20 to swing the matrix bar against the mould cavities as it moves down to the casting position, and to swing it away as it moves up to the ejecting position. In a modification, only one matrix bar is used, and is pivoted to the framing of the machine in position to engage either set of mould cavities when they, are down in the casting position. The metal pot is moved to and from the mould wheel by cams 33 on the shaft 34, engaging rollers 35 on bifurcated arms fixed to the pot. The plungers 49 are connected to levers 53 pivoted in brackets 54 on the pot, and having rollers 62 engaged by cams 63 on the shaft 34. The plungers are pressed down to inject the metal, when the cams 63 permit, by springs 56 on rods 58, 59, adjustable by clamping-collars 57 and screw-nuts 60. The plungers which eject the metal into the groups of moulds for types-less frequently used than others, are prevented from operating except at intervals. This is effected by pivoted hooks 64 engaging the levers 53 and preventing the downward movements of the plungers, except when the hooks are moved out of engagement. The hooks 64 are pressed by springs into engagement with cams 67 journalled on the pot 2, and rotated by pawls pivoted on the framing and engaging ratchet teeth on the peripheries of the cams, the cams being so formed and rotated as to permit of the operation of the plungers at the desired intervals. The shaft 34 is driven by gearing 37, 38 from a driving-shaft 39. The matrix bar is pressed against the mould wheel by fixed abutments 21 on the framing. As the mould wheel rotates, the cast types in the moulds are trimmed on their feet by a trimming-knife fixed on the framing. The ejector-slide 82 moves in a guide 84, and is reciprocated by rods 81 connected to cranks on a shaft 75. driven by gearing 73, 74 from the shaft 34. The slide 82 carries a series of ejector fingers 88, which push the types out of the mould cavities and into a set of passages in a transferring-bar 98 mounted on end pivots. A trimming-bar may be interposed between the mould wheel and the transferring-bar 98 for trimming the types on their sides. After the bar 98 has received the types, it swings to bring its rear side on to the upper end of the magazine 133, and with its type-passages in register with the channels or cells 134. The types drop into the channels 134, unless some of the channels are full, in which case the types which should have entered these channels are carried back by the bar 98. Surplus types in the bar 98 are pushed out by the incoming types, and fall into a shoot 127, which may return them to the melting-pot. The types are held in the passages of the bar 98, until they come into register with the magazine channels, by springs which project from the passages and are pressed to release the types by a bar 114 pivoted at 118 and operated by rollers 123 engaging cam inclines 121. The rollers 123 are on levers 122 operated by inclines on parts of the ejector slide. The bar 98 is rocked by levers 103 on a shaft 104 operated by an arm 108 and cam 110. The levers 103 are connected by links 102 to arms 101 fixed to the bar 98. The magazine 133 is adjustable by screws 136. The types pass into the channels 134, feet downwards and end to end, the foot of the lowermost type in each channel resting on a ledge at the rear of the channel. The lowest types are pushed off the supporting-ledges by sliding ejectors 142 operated by key levers 151, and pass on to a rapidly-moving endless spron 153 on rollers 154, 157, the lower one of which is continuously driven. A plate 160 supports the apron. Converging guides 161 direct the types into a tubular twisted guide 162, down which they pass successively to an assembling-box 163. Fig. 14 shows a vertical section through the assembly mechanism. At one side of the assembly box 163 is a slide 168 moving in dovetail guides 166, and having fixed to it a type-line pusher 169, by which the line, when assembled, is pushed out of the box 163. Sliding in a groove in the pusher blade 169 is a vibrator 171, the head 172 of which packs the types into the box 163 as they drop from the spout 162. The vibrator 171 is operated by a cam 174 and a retracting-spring. In the spout 162 is a type-stop 185 on a lever 183 operated by a rod 181, lever 179, and cam 177 to release the types when the vibrator 171 is in a retracted position The types are pushed by the vibrator past a catch spring 188. The types are supported by an abutment 195 projecting into the box 163, and carried by a long pivoted arm. When the line is assembled, the abutment 195 is withdrawn, and the line is pushed from the box 163 into the justifying-mechanism by the pusher 169, the slide 168 being reciprocated for this purpose by a rod 224, Fig. 3, connected to a crank-pin 223 on a shaft driven through a complete revolution by a clutch 211 each time the operator actuates a clutch lever 219. When the abutment 195 is withdrawn, the types are supported, as they move to the justifying-mechanism, by a spring 202, Fig. 24, at one side of the type passage. The types are pushed through an opening 206 in the wall of the justifier 229, Figs. 23 and 24, and the line is compressed to approximately its proper length between the end of the pusher 169 and the wall 203. The line is then pushed up between the walls 203 and 205, by a slide 226, and is finally justified in passing between the wall 203 and an adjustable block 253 having an incline 252. The elevator 226 has a slot and pin connection 232, 233 with a block 234 operated by a rod 236 connected to a lever 237 operated by a cam 222, Fig. 3. On the block 234 is an arm 240 having a roller 242 engaging a pivoted arm 243 pressed outwardly by a spring. As the block 234 moves down, the roller 242 acts upon the inclines 248, 247 of the arm 243, to push the elevated line into the galley 255. As the line moves upward in the justifier, a knifeedge 251 trims the spaces which may have bulged out from the line in the first compression. Fig. 56 shows a preferred form of compressible space having a slot or longitudinal recess b, and Fig. 58 one end of a mould cavity 3<a> for casting these spaces. Fig. 42 shows a vertical section of another form of machine. The metal pot 1<a> is pivoted to swing to and from the mould cavities, which are formed in a transverse bar 4<1> pivoted to swing on end trunnions. The matrix bar is fixed on the framing. After the types are cast, the mould bar 4<1> is swung into an inclined position, by a cam 54<1>, so that the types and spaces may be ejected by ejectors on a slide 35', in a guide 36<1>, reciprocated by rods 37<1> and cranks 38<1> on a shaft 39'. The types are ejected into pockets 57<1> in a rotatable reversing-bar 58<1>, which then rotates into the position shown in Fig. 42, so that the types fall, feet downwards, into the passages of a transfer bar 64<1>, and thence into the channels 65<1> of the magazine 66<1>. When the reversing-bar 58<1> rotates into position to receive a batch of types, the bar 64' moves to the right, from over the upper end of the magazine, so that any types therein, which have not passed on to the magazine channels, drop out. The plungers 9<1> are operated by levers 11<1>, cams 20', and springs 15'. The pot 1" is rocked by its arms 24', 25<1> engaging cams 28<1>. The lowermost types in the magazine 66<1> rest on ledges 68<1> and are pushed off by levers 80<1> operated by key levers 78<1>. The types pass through the outlets 82<1> on to an inclined endless travelling belt 83<1>, and are assembled in line by a vibrator on an arm actuated by a cam. The assembled line is engaged by pivoted pawls on a slide by which it is transferred to the justifier. In the justifier the line is compressed endways, and is at the same time pressed laterally to prevent the spaces from being disarranged. It is then lifted to the level of the galley, and pushed into it. The assembling and justifying mechanisms, and the driving &c. arrangements, of this machine are fully described in the Specification and drawings. Fig. 64 shows a method of maki
