Abstract: 9907. Gilbert-Stringer, H. J. S. May 13. Monotype and like machines. - Relates to a machine for casting justified lines of single types, which is a modification of the " monoline " typebar casting-macbine (Specifications No. 16,200, A.D. 1893, and No. 27,630, A.D. 1897). Matrix bars, Fig. 13, and expansible space bars, Fig. 14, are assembled in line and justified, and, after casting from them, are distributed as in the "mono- " line " machine, but single types and spaces are cast from the matrices successively and the lines are collected in a galley. The matrix bars a have the usual distributing-hooks b, and have the intaglio matrix characters on one of their faces instead of on their edges. One edge of the bar has aligning-notches c, and the other edge has recesses d which operate, and are of proper depth, to set the mould to cast types of proper thickness for the characters. Matrix bars for thin or narrow characters may be thickened by a definite amount, and such increased thickness allowed for in justifying by varying the space between the vice jaws after the manner described in Specification No. 1903, A.D. 1900. The space bars or matrices e, Fig. 14, each consist of two outer plates f, g pinned together at top and bottom, and a tapered blade h sliding between them. The blade h is pushed up by the justifying-mechanism to expand the platea f, g and justify the line. The bar has a distributing-hook i, and has also a notch k. The blade h is inclined on its edge, as shown at l, and the part of this incline in the notch k sets the mould to cast spaces corresponding to the distance the blades h are pushed up in justifying, and the thickness of each of the expanded space bars. Before distribution of the matrices and space bars, the blades h are pushed down by pressure on projections m. By depression of the keys n the matrices and space bars are released from the magazine o, and fall into an assembly box in which they are arrested at the proper height to align the characters corresponding to the depressed keys. They are pusbed from the assembly box into a line receiver s. As the matrices are assembled in the receiver s they engage a line abutment, mounted to slide, and connected to an adjustable alarm mechanism which is sounded when the line is nearly filled. When the line is completed, the operator pushes back a lever 11, and then pulls it forward, thus operating a clutch by which a line shaft 12 is driven through a complete revolution and then stopped. A cam 36 on the line shaft operates, through suitable linkwork, to advance a frame on which the line-carrier s is mounted, to bring the carrier into line with a raceway formed between two walls 44,45. The forward movement of this frame also operates a catch to release a pair of jaws 54, 55 of a justifying-vice carried by a sleeve riding on a spindle 53. The jaws are then swung by a spring, on a rod 57, into the line receiver. A cam 60 on the line shaft then operates through levers &c. 61, 62, 63 to move the vice frame, with the line of matrices &c., to the left. The vice frame is arrested with the matrices and space bars over a vertically-movably justifying- frame, which is then moved up, by the operation of a cam 65 &c., to push up the blades h of the space bars and spread out the line to the limit permitted by the vice jaws 54, 55. The justifying- frame is maintained in its raised position until after the whole line has been dealt with by the casting-mechanism. The movement of the vice frame to the left is now continued until the rod 57 comes over the end of a lever 76, and this lever 76 is then operated by a cam to raise the rod 57 and swing the vice jaws out of the raceway. During the second advance of the vice carriage, a carriage mounted to slide in the rear wall 45 of the raceway is moved by a cam 79 and linkwork 80,82, 83, 86, 85, &c. to the right, until a pawl on the carriage engages behind the right-hand end of the line. The carriage is then urged, by a cord and weight, to the left to press the line up to a stop wall 92 until all the matrices have been cast from and removed one by one at the left-hand end of the line. Each matrix, when pressed against the wall 92, is cast from and is then pushed to the rear, and the line is again assembled in a re-assembly box 99 to the rear of the raceway 44, 45. This box carries the re-assembled line, after the blades of the space bars have been pressed down, to the right until their hooks engage the distributer rods 108, by which they are returned to the magazine as in the " monoline " machine. The re-assembly box 99 is operated by stop collars on a weighted cord moved by the vice frame. Before the line shaft 12 completes its revolution, a cam 114 thereon operates a lever 115 and engages a clutch 122, 123, by which a letter shaft 126 is put into motion by gearing from a shaft 120 driven by a pulley 121. A type mould 132 is moved up to the front matrix through an opening in the wall 92 by a lever 130 operated from a cam 127. The mould has a body plunger, which is pressed by a spring 138, when a cam on the shaft 126 permits, until a projection on the plunger engages and is stopped by the recess d of the matrix a or the iucline l of the space bar. The mould has also a vertical plunger which, after the type is cast and the mould moved back, is raised so that the body plunger may move forward to eject the type from the mould into a channel 155 leading to the galley. The mould is preferably formed so that, when the jet piece is broken away from the type, a nick is formed in the foot of the type as described in Specification No. 20,953, A.D. 1900. The rear of the mould has attached to it a nozzle 144 sliding in a stuffing-box in the upper part of a pump suspended in the molten metal contained in the metal pot 146. The pump plunger 152 is operated by a lever 149 and spring 148, when permitted by a cam 147. The length of the channel 155, from the point where the types are delivered into it to the farther wall of the galley, is a multiple of the length of the line, and, when a line has entered the galley, it is pressed down into the galley by the operator depressing a presser-bar 164. Each matrix after it is cast from is moved to the rear along the wall 92 by a plunger operated by a lever 171 operated from a cam 166. The space through which the matrices have to pass in their rearward movement is filled by a number of thin leaves of metal mounted to slide to the rear when pressed by the matrix. The matrix presses back a number of these leaves equal to its thickness, and is moved to the right into the re-assembly box 99 by a plunger 181 operated by a lever and cam. When the last matrix has been cast from, the pawl on the carriage, by which the matrices are pressed up to the wall 92, passes through the opening in the wall, and a lever is rooked to cause the clutch 122, 123 to be disengaged and stop the letter shaft 126.
