DISTRIBUTING MECHANISM OF MATRIX-COMPOSING AND LINE-CASTING MACHINES.

To all whom it may concern:

Be it known that I, CARL MUnHLnIsnN, a citizen of the United States of America, residing at 2-3 Chausseestrasse, Berlin, N. 1, in the Empire of Germany, have invented new and useful Improvements in the Distributing Mechanism of Matrix-Composing and LineCasting Machines, of which the following is a specification.

The present invention relates to the distributing mechanism of matrix-composing and line-casting machines of the Mergenthaler type adapted to deal with matrices carrying alternative faces. These matrices stand or hang feet downward from the moment they are composed to the end of the distribution. Consequently, if the faces are arranged on the matrices one above the other, as they are, the matrices in a composed line of mixed faces, a. 9., roman and italic, will be at two different levels during composition, transference to the mold, and casting. The organ of the machine that presents the composed line to the casting mechanism is known as the first elevator. The lower level matrices hang therein by their top lugs, and the higher level matrices stand therein by their bottom lugs upon a ledge. This difference in level mustdisappear before the distribution can he proceeded with substantially, and is effected in the machines non made and sold, by the automatic retraction of the ledge from under the high level matrices, which are thereby left free to drop in the first elevator to the low level. The first elevator rises vertically from the casting position as far as a fixed stop known as the first elevator top guide. There is fast to and depending from the latter, a V shaped bar above the row of V shaped notches in the tops of the matrices, and as the said elevator reaches the stop, the said bar presses down to the lowest level, any matrix which may not have dropped thereto by its own weight. But it is the points of the distributing teeth projecting from the inclined sides of the V shaped notches in the matrices, that engage with the sides of the said V shaped bar, and this engagement is likely to injure the said teeth, by wearing away or bending down their points. The object of the present invention is to prevent such en- Specification of Letters Patent.

gagement and the consequent wearing and bending. To effect this object, the said bar has a ridge fast to it and depending from its apex edge low enough and thin enough to be engaged by the bottom of the well known vertical slot at the bottom of the V shaped notch in a matrix, before the distributing teeth of the latter can engage the sides "of the said rail. The ridge also serves to depress the sliding part of any spacer which may be still upstanding in the composed line.

Referring to the accompanying figure which is a side elevation from the left side of the machine, 1 is a matrix; 2, 3, its alternative faces; 4, the first elevator; 5, the front top lug of a matrix 1 by which it hangs from a rail 6 on the first elevator 42; 7, the front bottom lug of av matrix by which it would have stood upon a ledge 8 in the said elevator; 9, a spring pulling from the front of the elevator a upon the top of a lever 10 fulcrumed at 11 in the said elevator and having its bottom pivotally connected with the ledge 8 whereby the latter is retracted out of engagement with lugs 7 as soon as the above mentioned rise of the first elevator makes the bevel 12 on the lever 10 engage with the bevel 13 on the first elevator top guide 1 1; 15, the V shaped bar; 16, the V shaped notch in the top of a matrix; 17, 17, the distributing teeth projecting from the sides of that notch; and 18, the vertical slot at the bottom of a notch 16. 19 is a spacer hanging in the first elevator 4L by its lugs 20, 20.

21 is the ridge of the present invention.

The terms matrix, matrices must be herein understood as including type die, type dies with which a flong-indenting instead of a casting mechanism is used.

Having described my invention I declare that what I claim and desire to secure by Letters Patent is 1. In a typographical composing machine, the combination with a matrix formed in one portion with distributing teeth, of leveling means provided with a ridge which passes between the distributing teeth and engages and acts upon the matrix at a different portion.

2. In a typographical composing machine,
