Abstract: 22,521. Aix, F. C. L. d'. Feb. 25. Type-bar making machines; typecasting machines.-A machine which is particularly applicable for dealing with displayed work is adapted to cast slugs of adjustable length and width, the length being adjustable from an eight-inch line to a single type. The description is substantially identical with that of Specification 4818/10, but the claims are different. Assembling matrices. - The matrices are assembled in the holder described in Specification 4818/10, consisting of a drum 1 which is formed with longitudinal grooves to receive the matrices. The drum may be rotated by a ratchet-lever 4 to bring any of the lines opposite the mould, and the drum may be locked by a spring pin 7. The drum remains in the set position while " repeats " are being cast. Moulds.-The mould is of the kind wherein the top and bottom jaws are movable relatively for adjusting the length or for ejecting the slug. The means for adjusting the width of the mould is of the kind in which the top jaw is provided with an incline which may ride on a relatively fixed incline. The mouldslot is formed by jaws 21, 22 and end pieces 23, 24, the parts 21, 24 being mounted on a carriage 14 which is movable longitudinally in a frame 8 carrying the parts 22, 23. The end-piece 24 is mounted in the jaw 21, and is pressed downwards by a spring 25. The end-piece 23 is mounted to slide transversely to the jaw 22 and is pressed upwards by a blade-spring 27. To adjust the length of the slot, the parts 22, 23 are moved longitudinally in the frame 8 and set by a scale 48, and are then clamped by a screw 46 which enters a slot 44 in a slide 42 formed on the part 22. The width adjustment is effected by inclines 29, 31, the incline 29 being formed on the jaw 21 and the incline 31 being mounted to slide longitudinally in the carriage 14. The incline 31 is provided with rods 32, 33 adapted to engage stop-noses 34, 35 on a bar 36 which is mounted on standards 37 on the frame 8 and is secured in adjusted position by screws 39 and a pin 41. The frame 8 is secured to rods 9 which are mounted in fixed brackets and may be moved to and from the matrixholder by a lever 10 which engages a cam 12. The carriage 14 is reciprocated by a lever 16 which engages a face-cam 19. During the movement of the carriage 14 to the left, Fig. 6, from ejecting to casting position, the rod 32 engages the stop 34 and arrests the incline 31, the jaw 21 being thereupon moved downwards to close the mould to the required width, this being dependent on the position of the stop 34. The end piece 23 is moved downwards with the jaw 21 by means of a roller 52, which rides along a loose incline 51 on the end piece. When the mould is set, the frame 8 and the metal-pot described below move forward to bring the mould against the matrix-holder. After casting, the frame 8 moves back, and the carriage 14 then moves to the right with the jaw 21 and the end piece 24, the slug being carried to the right by the jaw 21 and sliding on the jaw 22. The jaw 21 is formed with lugs which engage recesses in the slug. During the movement of the carriage 14 to the right, the rod 33 engages the stop 35 and arrests the incline 31, the jaw 21 being thereupon moved upwards to open the mould to the full width to permit of ejection of the slug by the ejector 64 described below. Trimming type-bars.-When the slug is carried to ejecting position, the front and the rear faces are trimmed by knives, the knife 60 for trimming the top of the front face being secured to a block 55, which is mounted to slide in guides 54 in the frame 8 and is supported by a coiled spring which engages an arm 56. Ejecting type-bars.-The ejector is self-adjusting to the length of the mould-slot and is shown as consisting of a series of separate blades 64 which are actuated by separate springs 68 so that those blades which are opposite the slot are moved to eject the slug, while the other blades are held back by engaging the rear of the mould. The blades are released and returned by means of independent bell-crank levers 65, which engage a projection on a lever 66 riding on a cam 67. Galleys and galley mechanism.-The ejected slugs are pressed into a galley 69 by means of a bar 74 secured to slides 75, which are reciprocated from a cam 83 by means of levers 78, 80, 82. The galley is provided with a cross-slide 70, which is engaged by a detent, and is pulled upwards by a weighted cord 72. Metal pots and pumps.-The metal-pot 84 is arranged to ride upwards towards the mould, and for this purpose is provided with inclined shoes 85 which rest on trunnions 86. The pot is moved by means of a forked lever 87, which is operated by a cam 88 and is connected to the pot by a yielding connexion consisting of a sliding collar 90, which is pressed outwards by a spring 91. The down-stroke of the plunger 95 is controlled by a cam 102, and, to prevent back-suction, the plunger is returned slowly and independently of the cam by means of a spring 106. The plunger is connected to an arm 96 on a shaft 97, which is under the pull of the adjustable spring 106 and is provided with an arm 98, which is connected by a link 99 to a cam lever 100, there being a pin-and-slot connexion 104 between the parts 99, 100. The lever 100 rides on the cam 102 and, when released, is pulled downwards by a spring 103 to operate the plunger. The plunger is returned by the spring 106, the connexion 104 permitting of the independent return described. The tension of the spring 103 may be adjusted by means of a detent lever 112. The plunger may be locked by means of a pivoted catch 142. Driving-mechanism.-The cams are secured to a cam shaft 113, which is geared to a shaft 118 carrying a loose driving-pulley 119 provided with a clutch which may be operated by hand or foot. The clutch consists of shoes 120 secured to rods 121, which are mounted to slide in a spider 123 secured to the shaft 118, the rods being connected by links to a sliding collar on the shaft. The collar is engaged by a lever 126, which is secured to a shaft 127 provided with a hand clutch-lever 128. The lever 128 is provided in the handle with a spring locking-catch 129. The clutch-pedal 137 is connected by a link 136 to a pivoted plate 134, which normally holds back a spring-pressed rod 132 which is connected to the lever 126. After each cast, the machine is thrown out automatically by the engagement of a projection 140 on one of the cams with an arm 139 on the plate 134.
