Title: Improvements in and relating to typographical casting machines
IPC: B41B11/18
Filed: 1936-05-23
Abstract: 475,653. Type-bar-making machines. CLEMO, F. A. (Mergenthaler Linotype Co.) May 23, 1936, No. 14586. [Class 100 (iii)] Assembling matrices.-Machines having means for supporting two-character matrices at a higher or a lower level in the first elevator by means of a retractable rail are adapted for matrices bearing larger characters than usual by rendering the retractable rail vertically adjustable. As the lower characters of the large-character matrices project down to a lower datum-line than do those of the normal matrices, such matrices must be supported at a higher level than normal matrices, to cause their lower characters to register with the mould. For casting from the upper characters, the matrices are supported on fixed rails a, Fig. 2, in the elevator, as heretofore. The retractable rail B for supporting the matrices in the upper position is formed on a bar B 1, which is guided on inclined tongues g, Fig. 4, so that when the bar is moved endwise it will be raised or lowered. The tongues g are formed on a bracket-piece G, which can be moved in fore-and-aft direction in the elevator, in order to advance and retract the movable rail. The bracket-piece is operated by spring- pressed levers A<6>, which are rocked, in known manner, when the elevator rises into its upper position, in order to withdraw the retractable rail. The means for determining the level of the retractable rail comprise a hand-adjustable cam-block H, rotatably mounted on the viceframe and provided with high and low portions. The bar B<1> is urged to the right by a spring B<4>, so that it is cammed by the inclined tongues g into the lower position. When the elevator descends on to the vice-frame, the cam-block H engages an arm B<2> on the bar B<1>, and, if the higher part of the cam-block is in position, the bar is forced to the left, so that the retractable rail is moved into the higher position. The bracket-piece G has a retaining-lip g<6>, to prevent matrices at the lower level from being lifted frictionally by those which are raised.
