Abstract
424,575. Type-bar-makingmachines. MERGENTHALER LINOTYPE CO., 29, Ryerson Street, Brooklyn, New York, U.S.A., GORSE, W. F., Brelades, Brentwood Crescent, Altrincham, Cheshire, and SCOTT, R. H., 9, Manor Way, Bush Hill Park, Enfield, Middlesex. Aug. 23, 1933, No. 23456. Addition to 411,608. [Class 100 (iii)] Keyboards.-In arrangements in which one or more of a series or matrix keys for releasing space matrices of different thicknesses may be connected to the spaceband key at will, means associated with the keyboard are provided for disconnecting the spaceband releasing- mechanism from the spaceband key. The spaceband key 1, Fig. 1, actuates a rockshaft 2, which, as heretofore, selectively actuates one or more of the matrix keys 4 according to the adjustment of crank arms 5, which are controlled by handles or knobs 6. The rock-shaft also actuates the spaceband key-bar 7 through an arm 8, which rocks with the shaft. According to the invention, the arm 8 is carried by a collar 9, Fig. 2, which can slide without rotation on the shaft 2, and is adjustable by means of a rod 10 having a knob 18, in order to bring the arm 8 into or out of engagement with the key-bar 7. A detent 15 holds the collar 9 in either position. The connection and disconnection may be effected by other means, such as a clutch between the collar 9 and the shaft 2.
