Abstract: 559,158. Type-bar-making machines. MERGENTHALER LINOTYPE CO. Sept. 1, 1942, No. 12300. Convention date, Oct. 24, 1941. [Class 100 (iii)] The machine is constructed so that the organs not requiring manual operation are located substantially within the confines of a box-like frame structure, which is built up from corner-columns and transverse connecting members and comprises two or more sections bolted together. The frame structure can be encased in removable panels and is particularly adapted for machines of the kind described in Specification 551,171, in which each organ has an individual power-unit adjacent to it. In the case of a machine having auxiliary magazines, the frame consists of three main sections, the centre section A, A<SP>1</SP> supporting the main magazines and their pneumatic shiftmechanism, the right-hand section G, G<SP>1</SP> supportiing the auxiliary magazines, and the left-hand section H supporting the casting-mechanism. On the centresection are mounted, as sub-assemblies, which are complete in themselves, the keyboard-mechanism, the escapement-reed assembly, the assembly-throat mechanism, the second elevator, and the distributer. The casting-section includes as sub-assemblies the vice-frame, the first-elevator, the metal-pot, the mould-arm shaft, the ejector-mechanism, and the mould-magazine. The centre section of the frame consists of a base-frame A and an upper frame A', which are bolted together and each comprise vertical corner-columns connected by horizontal members, all the members being of angle or channel section and all the joints being welded. The upper frame A<SP>1</SP> contains the magazine shift-frame B<SP>7</SP>, which may be of the kind described in Specification 545,424, and a supporting-frame D for the removable keyboard described in Specification 559,147. The frame has brackets A<SP>32</SP>, C<SP>2</SP> for supporting the assembly-throat A<SP>33</SP> and the magazine control-device C respectively, and carries supports A<SP>35</SP>, A<SP>37</SP> for the distributer. The base-frame A contains an air-compressor A<SP>14</SP> and its motor A<SP>15</SP>, and also a water-tank and a pump for cooling the mould. The motor also drives a section F of a driving-shaft supported by the frame A<SP>1</SP>. The right-hand section of the frame-structure, which supports the auxiliary magazines, also includes base and upper frames G, G\ the upper frame having a bracket for the assembler-throat and a support G<SP>21</SP> for the right-hand end of the distributer. A section G<SP>37</SP> of the driving-shaft is detachably coupled to the shaft F. The left-hand section H of the frame, which supports the casting-mechanism, is bolted to the centre section and comprises a rectangular base H<SP>38</SP>, on which are mounted front and rear columns H<SP>1</SP> and a front left-hand column H<SP>28</SP>. Castings H<SP>9</SP>, H<SP>25</SP> extending between the front columns, support the metal-pot, the swinging mould-arm and the mould-magazine described in Specification 551,161, and the cam-shafts, which are detachably coupled to the shaft F. The front-plate J of the machine, which carries the assembler and the transfer-carriages and forms a sub-assembly, is secured by bolts to the left-hand column H<SP>28</SP> and to the centre section. The vice-frame and first elevator assemblies are secured by vertical hinge-pins to lugs H<SP>30</SP>, H<SP>31</SP> on the column H<SP>28</SP>. The second elevator is mounted on the lefthand rear column of the centre section. Specifications 551,185 and 553,033 also are referred to.
