To all whom it may concern:
Be it known that I CARL MUnHLnIsEN, a citizen of the United States of America, and residing at Chausseestrasse 23, Berlin, N. 4, Germany, have invented new and useful Improvements in Matrices for Typographical Composing and Casting Machines, of which the following is the specification.
In typographical composing and casting machines such as those known commercially under the trade mark Linotype it is known for the matrices just prior to their being dis tributed to be lifted singly by a so-called matrix lifter finger which raises them into engagement with the distributor screws, by which they are carried along the distributor bar In order to ensure that only one matrix shall be lifted at a time, the bodies of all matrices whatever their thickness are reduced to a common thickness along a central vertical line each by a central groove which reduces the said last-named thickness to that of the thinnest matrices to be dealt with by the distributor. When very thick matrices are used, this grooving considerably weakens the bodies thereof, so that the latter are easily crushed when the mold presses against them during the casting of the line.
The object of the present invention is to overcome the aforesaid difliculty by extending the groove in each such thick matrix downwards only to the extent which is necessary for allowing the matrix to be lifted into the distributing mechanism. I
In the accompanying drawings, which illustrate, by way of example, a number of constructional forms of the invention a Figure 1 is a side elevation of the distributor lift box in which the matrices are lifted into engagement with the distributor;
Figure 2; a side elevation of a thick matrix as now commonly used;
Figure 3, a central vertical section, and Figure 4, a plan of the same matrix;
Figure 5, a view similar to Figure 4 il lustrating the distortion to which such a matrix is liable;
Figure 6, a view similar to Figure 2 showmatrix according to the present invention;
Figure 7 a central vertical section of the same matrix;
Figures 8 and 9, views respectively similng one constructional form of the improved lar to Figures 6 and 7 of a second constructional form.
The distributor lift box a, which is of ordinary construction, has a ribbed bar I) along which the matrices 0 are pushed in the direction indicated by the arrow, and the foremost matrix is lifted by the constantly reciprocating lift finger at over the stop shoulders of the bar e in order to reach the distributor screws, all in the well-known manner. In order to ensure that only the leading or foremost matrix shall be lifted, a thin blade fis fitted, also in the known manner,to the ribbed bar 72, the said blade being adapted. to engage the central groove g of the matrix. Between the front edge of the said blade f and the aforesaid stop shoulders against which the leading matrix bears there is only suflicient room to accommodate the thinnest matrix, all matrices other than these thinnest ones each having a groove g (Figures 2 and 3) which receives the blade 7 when said matrices are raised, so as to prevent any but the leading matrix being lifted by the finger d.
When a very thick matrix has to be dealt with, such as that illustrated in Figures 2 and 8, the central groove 9 considerably weakens the body thereof, this weakening being greatly accentuated in matrices in whose feet are provided font distributing notches such as that marked it in the figures now under review. When matrices of this description are present in a composed line, it may easily happen that they become crushed by pressure against the casting mold and consequently deformed in the manner shown in Figure 5.
The object of the present invention may be attained bythe constructional form shown in Figures 6 and 7, according to which the matrix has the usual groove 9 milled into it. this groove-being afterwards tightly filled in, at its lower part, by a strip a, which latter is distinguished by hatchet lines in said figures.
Further, as shown in Figures 8 and 9 the matrix may, after it has been provided with the usual groove 9, be drilled through to receive a plug 0 which will act as a reinforcing member and prevent the matrix from being crushed in.
Having described my invention, I declare that What I claim and desire to secure b Letters Patent is v v 1. In or for a linotype machine, gjmatri formed with a separating sldti'e'iztending practically throughout the length of the matrix and provided With a reinforcing plug to prevent the collapse of" the matrix',"th'e said reinforcing plug being located at a point far enough below the utiriefiidbf 10 the separating slot to ermit rna tri g z to be lifted into engagement with the distributing mechanism of said linotype machine.
QZJA matrix" according to claim 1, characterized by the fact that the reinforcing plug therein recited is in the form of a filling piece inserted in the lower part of the slepa'rating slot.
In testimony whereof I have aflixed my signat nie'lierto.
CARL MUEHLEISEN.
