Abstract: 24,497. Rogers, F. H., [Hatch, A. C.]. Oct. 26. Type-bar making machines; keyboards; justifying, clamping, and alining matrices. - The matrices 36, Fig. 13, are carried by pivoted rods 39 and, when released by the keys, fall into the assembling position by gravity, the line of matrices being assembled in a vertical position. The rods 39 are pivoted in vertical channels 41 which are arranged in two arcs on tables 30, 31, Fig. 2, one on each side of the assembling point. The matrices are released by escapements each consisting of a rotatable shaft 42 which passes between the two branches of each rod 39 and has at its end catches which retain the rods. The shafts 42 are rotated by air-cylinders 48 to which air is admitted by valves operated by cams loosely mounted on a constantly rotating shaft. The cams are locked to the shaft so as to rotate with it by the depression of keys. Two series of wedge-shaped justifying-bars are mounted similarly to the matrices, one on each side of the assembling point. One bar is released from each series by the operation of the space-key so as to form a double-wedge spacer. The justifying-bars are arranged to slide, and are driven in opposite directions in order to justify the line. The released matrices fall upon a shelf 35 formed at the foot of a block 33, shown in plan in Fig. 7, which serves as an abutment for the line. The matrices are alined vertically by pivoted side jaws 144 which are pressed apart by springs and are closed together by a forked bar 153 operated by a cam. The matrices are clamped against the vertical face of the block 33 by the metal-pot, which forces the mould 182 against the matrices. The line is clamped at the top by a pivoted plate 169, Fig. 6, which is pulled down by links 172 and a cam. A pin 179 on the plate 169 enters a recess 180 in the mould. After the line is cast, the matrices are raised into engagement with the escapements by vertically sliding rails. Moulds.-The mould is carried by an arm 183, Fig. 2, on a shaft 184 which is rotated by a rack, a pinion, and a cam to carry the mould between the casting and ejecting positions. The shaft is movable lengthways to permit the mould to move to and from the matrices. Metal-pumps.-The plunger of the metal-pot 164, Fig. 2, is connected to a rod 221 pivoted at its upper end to a pin 223 which slides in a sleeve secured to a bracket 29. The plunger is forced down by a spring 225 and is raised by a lever 227 and a cam. Ejecting type - bars; galleys and galley mechanism.-The type-bars are ejected from the mould by a plate 201 carried by a sliding bar which is actuated by a cam. The galley 202 is removably secured to a bracket 216 and is provided with a pusher 217 to push the slugs into the galley. Driving-mechanism.-The machine is operated by a cam - shaft 88, Fig. 2, which, upon the operation of a hand-lever 129, is driven for one revolution from a constantly rotating shaft 89, Fig. 22, by means of an expanding frictionclutch 92. The driving-member 91 of the clutch is carried by a sliding sleeve 96 and is pressed towards the driven member 93 by a spring 98. The sleeve 96 is secured to a rod 99 passing through the shaft 89 and having a collar 102 which bears against an eccentric pin 105 carried by a shaft 107. The pin 105 is normally in line with the centre of the shaft 107 and holds the clutch open. The hand-lever withdraws a locking-pin and rotates the shaft 107, whereupon the clutch is closed by the spring 98. The clutch is opened after one revolution by a cam on the shaft 88, which rotates the shaft 107 back to initial position. The shaft of the hand-lever is connected to the plate 169 which clamps the end of the line, so that the machine cannot be started if the line is too long.
