Title: Improvements in or relating to wipers for the trimming knives of typographical line-casting machines
IPC: B41B11/72
Filed: 1936-03-14
Abstract: 471,977. Type-bar-making machines. WALKER, V. E. (Mergenthaler Linotype Co.) March 14, 1936, No. 7721. Addition to 373,144. [Class 100 (iii)] Trimming type - bars.-In trimming - knife wiping-mechanism of the kind described in the parent Specification, in which the wiper is operated by the movement of the first elevator, automatically controlled means are provided for keeping the extent of the wiping action constant, regardless of the casting level at which the elevator is arrested. In casting from the larger sizes of matrices, the elevator A, Fig. 1, is arrested, in known manner, at a higher level than usual by two filler-pieces F, F', shown in plan in Fig. 4, which are pivoted on the vice frame, and one or both of which can be interposed in the path of a stop - pin D on the elevator. The lower fillerpiece F<1> is secured to its pivot-rod f, which can be turned by means of a knob f<5>, and the upper piece F is loosely mounted on the rod, and is turned into operative position by hand. The wiper G is operated, as heretofore, by a rod g connected by a link g<3> to a spring-raised rod g<5>. The rod is driven down to operate the wiper by a pin J on the elevator, which acts through the interposed arm of a lever O pivoted on the elevator. When the elevator is arrested in either of the higher positions, a slidable banking-block P is moved into the path of the free end o<1> of the lever O. A rocking movement is thereby imparted to the lever, which moves away from the pin J and imparts an additional movement to the rod g<5> to that which it receives from the elevator. The wiper therefore makes a full stroke in spite of the reduced movement of the elevator. The sliding movement of the banking-block is effected automatically by connections from the filler-piece F<1>. The block is in two sections pivoted together, and, when the second filler-piece F is brought into use, one section is turned over on to the other by hand, so that the height of the block is increased.

In operation, a selected question card is inserted into the aperture E and is moved by hand to be viewed in zone ZA; then chosen answer cards are inserted, one by one, and likewise manually shifted to the zone ZA; thus pushing the question card along also. During this movement, marks on the question card and on the answer cards are scanned by OF and OA which respond, if the answer cards represent a correct answer, to activate an optical and/or acoustic signal and to actuate a solenoid (Figs. 4 and 6, not shown) whereby the question card is stored in the zone ZK and the answer cards are fed through the aperture W for further use. In the event of an incorrect answer, the solenoid does not respond and has to be unblocked by inserting a specially marked " erase " card into the aperture E; this card is manually pushed into the zone ZA, and then by means of a second erase card, into the zone ZK (where it is stored to register an error), the question and answer cards being thereby ejected through aperture U. Thus correct and incorrect answers by a student can be fully  monitored. In a modification, the scanner OA may be replaced by a student operated keyboard producing signals for comparison with the signals generated by OF. The markings may be optical, as described, magnetic, electrically conductive, or in the form of preforations or serrations.
