JULIUS DORNETH, OF BERLIN, GERMANY, ASSIGNOR TO TYPOGRAPH-GESELLSCHAFT M. B. H., OF BERLIN, GERMANY, A CORPORATION OF GERMANY.
MATRIX-BAR FOR LINE SETTING AND CASTING MACHINES.
Specification of Letters Patent.
Patented June 22, T915.
To all whom it may concern:
Be it known that I, JULIUS DORNETH, a subject of the German Emperor, and residing at Berlin, Germany, have invented certain new and useful Improvements in h latrix-Bars for Line Setting and Casting Machines, of which the following is a specification.
My invention relates to improvements in matrix bars for line setting and casting machines, and more particularly for machines in which the matrix bars are guided on wires for guiding the same into assembled or distributed positions.
T 0 permit the use of the same matrix bars for composing lines in which types of different styles or faces are used, it has been proposed to make the matrix bars in two sections which are shiftably connected with each other. Though such matrix bars are suitable for composing lines with types of three or more different styles, they have not come into practical use, because it is difficult to connect the matrix bars in a reliable and rigid way. The difficulty of providing a reliable connection resides in the fact, that the matrix bars can not be made thicker at the joints of the sections than the steel part of usual matrix bars which can not be extended, and because a certain clearance must be provided at the joints between the sections, in order that the friction of the sections when shifting the same is reduced to a minimum.
The object of the improvements is to provide a matrix bar consisting of two sections, in which the joint of the sections is reliable, in which the friction of the sections when being shifted is small, and in which the thickness of the bar at the joint is not larger than that of a matrix bar of ordinary construction.
tion an example embodying the same has been shown in the accompanying drawing, in which the same letters of reference have been used in all the views to indicate corresponding parts.
In said drawingFigure 1, is a side view of the matrix bar, and Fig. 2, is a cross-section of the same.
In the example illustrated in the drawing the matrix bar consists of a shaft a madeof steel and has at its lower end an enlarged head (not shown) for receiving the types, said head being made from brass and having the usual thickness. At its upper end the shaft a is formed with a longitudinal groove or channel Z) which is made in the narrow side face and extends to the upper end of the shaft. The said groove receives the upper section 0 and provides a guide therefor, so that the section 0 is inclosed at three sides. The section 0 is formed with the usual eye 0 for suspending the matrix bar from the wire. It is formed with a longitudinal slot 6 which is engaged by a transverse pin 03 secured to the shaft 0. As appears from the drawing, the part c is guided with its whole length within the groove Z), so that a reliable connection is obtained. The side walls of the groove can not be bent apart.
I claim:
1. A matrix bar comprising two sections,
