Abstract: 24,933. Ransford, R. B., [Oddur Manufacturing Co.]. Oct. 29. Single-type composing and casting machines; keyboards; driving - mechanism; matrices. - In a key-operated machine, the matrices are carried on the sides of a series of disks or rings which are movable axially to bring any one disk into operative position. The selected disk is rotated to bring the required matrix to position, and is moved transversely to its axis to present the matrix to the mould. The key-levers 2, Fig. 12, are connected to push-rods 3, which raise stops 6 into the path of a lug 8<b>, Fig. 12, on a sliding selectorbar 8. The keys are divided into two groups, which move the selector-bar and rotate the matrixdisks in opposite directions from normal position. The bar 8 is moved by a rack and a pinion 9 on the shaft 10, which rotates the matrix-disks. The shaft 10 is rotated by a pinion 11, sector 12, arm 14, and link 15 from a lever arm 16, Fig. 9. The arm 16 is raised or lowered so as to rotate the shaft 10 in either direction by two cams 30, which act through yielding connexions on bellcrank levers 17 either of which may be connected to the arm 16 by a pivoted dog 16<b>, which is rocked by two universal bars operated by the halves of the keyboard. The matrix-disks 42, Fig. 7, are mounted to slide without rotation on a stationary barrel 41, and are confined between two rings 43 carried by a block 43<a>, Fig. 5, which slides in a frame 40. The matrices 42<a>, which may be individually set in the disks or made up in sections, are mounted in the side faces of the disks, and are held in place by concentric clamping-rings. In the back of each matrix is a hole 42<d> to receive an alining and locking device. Between the ends of the barrel is a gap in which is located a disk 45, of the same diameter as the barrel, and normally in alinement therewith. The disk 45 is mounted on an eccentric 46 carried by a shaft 44, and carries on its face a block which is embraced by guides 10<a> carried by the shaft 10. Rotation of the shafts 44, 10 thus causes the matrix-disk which is supported by the disk 45 to be moved transversely to its axis into the position shown in Fig. 7, and to be rotated to an extent determined by the key depressed, so that the desired matrix is brought opposite to the mould. The shaft 44 and eccentric 46 are rotated through half a revolution, and are subsequently returned to normal position by a cam. In order to bring any required matrix-disk into operative position, the series of disks is moved along the barrel by a stepped cam 99, Fig. 5, which engages a roller 43<c> carried by one of the rings 43. The roller is held against the cam by a spring acting on the sliding block 43<a>, and the cam is rotated by means of a shift key or lever. Means may be provided for retaining a disk in the lower or operative position when a number of characters are to be cast from the same disk, the disk being merely rotated by the action of the keys. The operative matrix-disk is moved against the face of the mould by a cam-actuated wedge acting upon the matrix-barrel frame 4C, which can slide in bearings in the machine frame 72 against the pressure of springs. The matrix is held against the mould by a cam-actuated plunger which enters the hole 42d in the back of the matrix. Moulds.-The mould is formed by fixed plates 67, 68, Fig. 23, a vertically-movable slide 69, and an horizontally-movable plunger 70, which determines the set-width of the type and ejects it from the mould. The slide 69 has a channel 69<a>, which can be brought into alinement with the mould, and through which the type is pushed into a line-channel 71. Stops 69<b>, 72<a> determine the alinement of the channel 69<a> with the mould. The plunger 70 is adjusted by a wedge 77, which is connected to the plunger that clamps the matrices against the mould. The clamping-plunger engages recesses in the backs of the matrices, the depth of which is proportional to the size of the type, so that a corresponding movement is imparted to the wedge 77. The cast type is ejected by the plunger 70 under the influence of a cam-actuated lever 78, the plunger 70 being slotted so that it may move relatively to the wedge 77. Metal pumps.-The metal-pot is provided with a pump, which is oscillated by a cam to move the spout of the pump to and from the mould.
