Abstract: 18,766. Imray, O., [Monoline Composing Co.]. Sept. 16. Linotype and like machines. - Relates to monoline type composing and casting machines, reference being made to Specifications No. 17,135, A.D. 1893, No. 27,630, A.D. 1897, No. 2181, A.D. 1899, and No. 9357, A.D. 1900. (1) The composing- box mechanism is shown in Figs. 3, 4, and 16. The oscillator 5, instead of being provided with a series of levers and springs, is provided with a series of weighted pawls 8. The shaft carrying the camoperating roller 7 is mounted in an eccentric sleeve turned by means of a recessed head 10a, so that the throw of the oscillator can be adjusted. The matrix-bar arresters 14 are pivoted in vertical series between distancepieces 15 projecting from a plate 16 forming one side of the composing- box. In the opposite side side 16" of the composing- box is arranged a series of yielding fingers 2 constituting matrix-bar keepers to prevent. rebound of the matrix bars, which are provided with a supplemental recess at the lower end for this purpose. The arresters 14 are projected by slides 18 on operating the keyboard, and returned by means of a yoke 37 operated from the oscillator. The keepers 2 are projected by springs 22 and controlled by the corresponding arresters 14 through cam-pieces 2<a>, 14<b>, the arresters being dropped as shown at 14<c> to provide the necessary difference of level at the ends. The rear wall of the composing space 21 is formed by a post 23 having an extended base closing the lower end of the space 21. At the upper end of the post 23 is a guide-block 25 having a keyhole slot in which works the ejector 26. The falling matrix-bars are guided at the rear by a wall 31, the lower end of which is made up of the bevelled front faces of the ejector 26 and guide-block 25. The front wall 32 is movable into and out of the box, and a movable division plate 32<a> is provided for preventing tilting of the matrix-bars. The parts 32, 32<a> are connected with a rod 33 operated from the shaft 9<a> of the oscillator cam 6. The matrix-bars are guided from the composing-box on to the assembly rail by a bridge 29, which is held retracted by a spring, and projected during the advance of the ejector by means of a cam lug normally received in a cam recess in the ejector. (2) The line-carriage mechanism is shown in Figs. 22 and 23. The fixed assembly rail 28 is arranged so that it enters part way only into the alining-recesses in the matrix-bars, and a travelling alining-rail 41, moving with the line carriage, is provided to enter full depth into the recesses and engage with inner portions not worn by the fixed rail. The rail 41 is mounted upon a slide 42 by means of cam slots and pins, and is moved into and out of the recesses in the matrix-bars by means of bevelled spring pins 47, 47<a>, a channel being formed in the rail 41 for the passage of the pin 47<a>. The slide 42 is connected with the line-carriage by an arm 44<c>. The movable abutment in the line-race comprises a head 49, Fig. 16, provided with fingers 50 and connected with a spring piston 51, the barrel 52 of which is pivoted at the end. The fingers 50 are swung out of the line-race by means of a two-armed lever engaged by a pin 54a on a line-moving wing 63 of the linecarriage, and are introduced by means of a pusher. The line-carriage comprises a base 57 and uprights, in which is mounted a shaft 60 carrying a bracket 61 detachably connected with a head-block 62. At opposite ends of the shaft 60 are secured the line-moving wing 63 and a line-locking arm 64, which are swung clear by means of a spring con. nected with the shaft 60, and swung into operative position by an arm on a shaft operated by the starting-lever, and locked by a catch 69. During the movement of the parts 63, 64 into position, the head-block is moved up by a pusher-projection on the arm 64. (3) The mould E, Fig. 32, is connected with its operating-lever 84 by a link 86 arranged for ready disconnexion. The link 86 is provided at one end with a pin 87 fitting in a socket in the mould, and this end is also cut away at 96 and fits under a ledge 94 on the mould. At the opposite end, the link 86 is perforated to fit over a stud on the lever 84, and is retained by a pivoted button 91. The knife-wiper 97 is mounted directly on the link 86. A lug 97<a> on the wiper engages with a guide to move the wiper clear of the knife, against the action of a spring 98, when the mould moves to casting position. (4) The distributing-mechanism is shown in Fig. 38. Preparatory to distribution, the line is loosened by release of the catch 69, Fig. 23, through a trigger 104 and a trip on the justifying-shoe, and imparting a partial swing to the parts 63, 64 through a finger 69a, sufficient to bring the pusher-projection on the arm 64 into a recess in the head-block.- The loosened line is levelled by the depressor. The lifter plates 107 are movably arranged in guideways of an elevator 110 moving between uprights 111, the ascent being effected by means of a lever 112 and cam 113, and the descent by gravity, or both movements may be effected by the cam. The lateral movement of the plates 107 is effected by means of a rack 122 on the lowermost plate 107, and a gear-wheel 119 moving with the elevator and engaging by a pin 121 in a spiral groove 115 in a post 114. The upper plates are actuated from the lowermost plate by means of a pin working in slots of different lengths. Stops 126 are provided on the rear ends of the plates. The post 114 is mounted in a step bearing 116 and adjustable in a bracket 117 by means of nuts 118. A stripper-plate 127 is actuated from the linemoving lever by means of a roller stud Y-lever, link, and lever. (5) The dog 133, Fig. 50, is provided with an additional bevel 133a for unclutching in case of reverse motion of the driving- gear.
