Abstract
499,036. Type-bar-making machines. LINOTYPE & MACHINERY, Ltd., and HARRISON, V. C. J. July 17, 1937, No. 19876. [Class 100 (iii)] Clamping matrices.--Automatically operated means, preferably actuated by the justificationmechanism, are provided for periodically wiping the clamping-face of a jaw, more particularly in machines equipped with quadding and centring mechanism. A vertically reciprocating wiper 1, such as a pad or brush, is carried by a lever 2, pivoted to a second lever 3, which is pivoted on the vice-frame. The lever 3 is connected to the upper end of a slide 6, the lower end of which extends into the path of the justification cross-head 8. The levers 2, 3 are connected by a spring 11, and, in the normal lower position of the wiper, the lever 2 rests against a fixed cam 12. When the cross-head 8 descends after a slug has been cast and the jaws are in open position, the wiper is raised and passes across the face of the jaw, against which it is held by the spring 11, Wiping means may be applied to either or to both jaws.
