Abstract: 13,342. Lock, W. H., [Thorne Type Setting Machine Co.]. June 12. Type, setting.-A machine for use in justifying type comprises means for measuring a line of types, dividing the ascertained shortage in accordance with the number of word spaces, setting a gauge to give the required thicknesses of the justifying- spaces, feeding as many pieces of wood to the cutting-apparatus as may be required for each line of types, and cutting off spaces of the necessary thicknesses. The pieces of wood 60 arefed forwards by vertical rolls 70, 71 provided with pinions 64, 65 actuated by a rack 66 connected to a forked bar 67 which bridges a cam 68 on the main shaft 20. Each roller 70 is capable of lateral movement, and, during the feeding-motion, is moved towards its companion roller 71 by a forked wedge 72, carrying a loosely-pivoted lever 73 ; the upper ends of all the levers 73 engage with an arm 74 and their lower ends engage with an adjustable abutment 80. The arm 74 is actuated by a cam 77 on the shaft 20, but transmits motion only to those wedges 72 the levers 73 of which are opposite the abutment 80. The abutment-bar is formed with ratchet teeth 81 engaging with a pawl 82 pivoted to an arm 83 fixed to the space-key shaft 46. When the composing of any line is begun, the abutment 80 is clear of all the levers 73, and then, as the key 45 is depressed for each word, the abutment is moved behind the levers 73 in succession, causing, as the cam 77 rotates, the corresponding wedges 72 to force their rollers 70 against the pieces of wood 60, which are next fed forwards. In this way, as many pieces of wood are fed as there are spaces in the line. The justifying-lever 25 is connected, at one end, to the vertical measuring-slide 47, and is supported upon adjustable bearings 29 formed on a block 28 sliding freely along the bar. The graduations marked 0-9, on the bar 25, indicate the positions of the bearings when justifying lines with the corresponding numbers of word spaces. Springs 33 tend to draw the bearings towards the right against spring stops 34, which are raised in succession, as the composing proceeds, .by means of a lever 36 pivoted on the block 28, and operated from the space key 45 ; the lower ends of the stops are bevelled. The slide 47 extends into the type-channel 48, and rests upon the types, separated in the usual way by separators s. The right-hand end of the lever 25 rests upon an extension 12 of a vertically-movable gauge-bar 10, which has a lower extension 13 carrying a spring thrust-collar 17, resting upon a lever 18, actuated by a cam 19 on the shaft 20. Inclined lugs 14 on the bar 10 fit against an inclined part of a gauge 49 having a series of fingers which slide within mortises in the cutterslide 51 ; the wood pieces 60 are fed into these mortises against the ends of the fingers, the mortises registering with passages through a fixed cutter-block 54. The cutter-slide is actuated by a cam 52, and cuts off the ends of the wood pieces projecting beyond the cutter-block. The severed ends or justifying-spaces S are then carried by the slide 51 to spacer channels, into which they are ejected by the fingers. The spaces fall from the channels upon an inclined apron 57, and are substituted, by band, for the separators s.
