Abstract: 180,088. Golby, F. W., (Wilson Displayotype Machine Co.). Feb. 28,1921. Type-bar-makingmachines ; singletype composing and casting machines ; matrices ; moulds ; metal-pots ; galleys.- A machine for casting in order of composition type, which are subsequently bended into lines comprises a series of matrix-carriers in the form of chains or bars suspended within a frame which is moved horizontally to effect the selection of a chain or bar which is then moved vertically in permanent guides to position the desired matrix in front of the mould. The chains of matrix-carriers 15, Figs. 1 and 4, are enclosed within a. rectangular frame 7 provided with rollers which run on tracks 8 formed on the side-members 3, 4 of the machine frame. The carriers 15 forming a chain are pivoted together and are suspended from plates 26 having lugs which slide on the, tracks 8, two rows of carriers being attached to each plate 26. Each carrier 15 is formed with compartments 16, Fig. 13, to receive the individual matrices 17, which are retained by a cover-plate 20. Each chain of matrixcarriers comprises a number of different founts of the same character. The sideplates 3, 4 are formed with vertical guides 28 in which slide conveyers 30 by means of which a selected chain is lowered to the casting-point. The conveyers 30 are operated by levers 35 from a hand-lever 44. In order to select a particular chain, the frame 7 is moved horizontally by means of a rack 50 and a spur-wheel 53 which is operated by a crank-handle 60 provided with an index-plate. 62. The vertical movement of the selected chain is limited, according to the matrix required, by a stop 70, Fig. 4, which is provided with gradua. tions 74 and is adjusted by means of a handwheel 73. The matrix-carrier is clamped against the mould-wheel 75 by a pivoted clamp 110, Fig. 1, which is operated by cams 118<a> from the handlever 44. The clamp is provided with a central partition 120, Fig. 8, which closes the open sides of the matrix-compartments 16, and with sliding spring-separated members 121 which are forced towards each other by fixed inclines in order to grip the sides of the matrix-carrier. The clamp is provided with a member for detaching the matrix from the mould. A fixed projection 135, Fig. 4, separates the two rows of carriers forming the chain. The mould-wheel is provided with rows of casting-chambers 80, Fig. 16, and is rotated through 90‹ after each cast by means of ratchet-mechanism and a toothed segment which is operated by the hand-lever 44. The cast type, is ejected by one of a series of rods 95 which register with the mould-chambers 80, an additional rod being provided to engage apertures 81 and lock the mould-wheel in position. The metal-pot is pivotally mounted and is adjusted by suitable means to bring the nozzle into register with the proper mould-chamber. The type, which are provided with short stems 171. Fig. 15, are received in a collecting-stick 150, which is pivoted at its lower end and comprises a slotted plate 151, Fig. 10, through which the stems of the type pass, and a back plate 153. A sliding slotted plate 154 guides the ejected type from the mould. The lines of type, after beinq justified, are formed into type-bars by means of a slug-casting machine.
