TABULAR ATTACHMENTS
There are two attachments in common use for setting tabular composition. These are the Chicago Lino-Tabler and the Rogers Tabular.
The Chicago Lino-Tabler equipment can be used on any model machine with any font of matrices from 5 point up to and including 14 point. This equipment consists of twenty matrices, a broach, quad block and slide for casting box rules, and special triangular-shaped brass rule for use between columns.
The matrices are cut to run in the vertical rule channel. In the matrices are two small slots from which two lugs or fins are cast on the slug. When using these matrices on the models 9, 16, 17, and 24, the magazine in which they are to run must be designated.
There are four styles of rule available, two hairline faces, a one-point face, and parallel rules. The rules are held on the top surface of the slugs, and are clamped down by bending the lugs or fins over with a make-up rule.
Cross rule is cast in the regular slug form from the block and slide. Box headings or rule forms are made by using the broach which punches small triangular notches through the top edge of the rule slug. This permits the vertical rule to be inserted, forming a close joint.
The Rogers Tabular can only be used on machines that are equipped with the attachment. When using this attachment the matrices that run in the vertical rule channel are used in the assembled line where rules are wanted. From these matrices on the slug are cast two slots in which the rules are inserted. All other characters are punched .144 of an inch deeper than the standard, which necessitates using a low mold. When changing from regular to tabular, first turn the tabular mold into normal position; second, move lever which is attached to the eccentric pin in the mold cam lever so it is locked in the rear sector block. Doing so moves the mold slide forward the difference in the thickness of the regular and low mold. Third, loosen screw and turn eccentric bushing in pot lever half way, which moves pot forward the distance the mold slide has been moved. Fourth, connect one end of the return spring to the hook which is in the rear of the machine. This spring is for the purpose of relieving the mold cam lever of the added strain when the slug is moved from the line after casting. It is also necessary to use the tabular spacebands, which also can be used with standard matrices.
