To all whom it may concern:

Be it known that I, JULIUS Donxn'rn, a subject of the German Emperor, and residing at Berlin, Germany, have invented cer- 5 tain new and useful Improvements in Matrix-Setting and Line-Casting Machines, of which the following is a specification.

My invention relates to improvements in matrix setting and line casting machines,

and more particularly in that class of machines in which the lines are cast from a plurality of matrix bars each of which is guided to or from the mold holder on ways in the form of wire stretched on a frame to form a matrix carrier. Machines of this type are shown for example in the patents of the United States to Bright Nos. 487,1 l1 and 557,184; and to Rogers No. 557,232. In machines of this character such as are now constructed the rrame to which the rear ends of the wires are secured is slightly curved, so that the wire ends are located substantially one beside the other within a plane which is perpendicular to the line. With this construction of the frame the matrix carrier must be very large, so that a considerable force is necessary to rock the same. This is particularly the case, where the carrier is equipped with several sets of matrices. In

this case also the length of the ways or wires and the heights at which the matrices fall are very large.

One of the objects of my present improvements is to so construct the said frame, that the size of the-carrier is considerablv reduced. And with this object in view my invention consists in constructing the carrier in such a way, that the rear ends of the wires are located in a plurality of ad acent rows 40 or groups of rows.

In order that my invention may be more clearly understood several examples cm bodying the. same have been shown in the accompanving drawings, in which the same letters of reference have been used in all the views to indicate corresponding parts.

In said drawingsFigure l, is a side view of the most simple embodiment of mv inven tion showing the machine and its wire can rier in a diagrammatical way, Fig. 2, is a plan of Fig. 1, Figs. 2 and 3 to 6, are diagrammatical plan views showing various modifications of the carrier, and Fig. 7, is a side View of Fig. 6.

Referring to the example illustrated in Figs. 1 and 2, the bed of the machine frame A and the parts mounted thereon are of any known or preferred construction. On the machine bed a matrix carrier B has a rocking support by means of pivots a. The car-- rier consists of an upright standard 8, a frame 6, and ways or wires 0 for guiding the matrix bars. At their front ends the wires 6 are secured to the standard 8 and at their rear ends to the frame I). As shown in Fig. 2 the said frame is formed with a pair of branches or side bars b Z) which are located one beside the other and connected at their rear ends by a yoke b so that the general form of the frame resembles that of the letter U. The rear ends of the wires are secured to the branches or side bars 6 7) of the U-shaped frame 6, so that they are arranged to two adjacent rows which in the example shown are parallel to each other and to the line of set matrix bars. The wires of each group extend inwardly from their rear ends in parallel relation for a suitable distance, the wires of each group being arranged one above the other and merging in a common vertical plane at the inner ends of their parallel portions, extending forward in said common vertical plane to the standard. Near the frame F) a bow (Z is located which has likewise the form of the letter U, and which carries the latches for maintainin the matrix bars in their distributed positions.

In the example shown in Fig. 2 the branches 7), b of the frame I; are divergent, which is preferable in this respect, that the wires at the front ends of the branches are thereby somewhat increased in length, whereby the velocity at which the matrix bars fall downward is reduced.

In the modification shown in Fig. 3, the U-shaped frame a is broader than the frame shown in Figs. 1, 2 and 2 and between the branches or side bars 6 e a pair of branches c, e are provided which have substantially 00 the same direction therewith. Thereby four rows of wire supports are formed which are parallel or nearly parallel to one another. As shown to the outer branches 6 e a larger number of wires are secured than to the inner branches 0*, e If the matrix carrier is used in a machine with two sets of matrix bars. the latter are preferably so arranged on the carrier, that one complete set is suspended from the wires of the right hand 1 branches, and the other one from the wires of the left hand branches, so that the movement of corresponding matrices on their wires requires exactly the same time in both sets. The key board 9 is divided, and it is provided in each section with a complete set of keys.

The example shown in Fig. 4 is similar to that shown in Fig. 3 in so far as the frame It is provided with four branches if, h, 71, k But the wires 0 are so connected to the inner branches h, if, that nearly the same number of wires can be secured to all the branches, for which purpose the wires are alternately directed from the branches to opposite sides.

In the example shown in Fig. 5 the frame is provided with more than four branches, and it has substantially the form of a rack. As shown eight branches 2' to a" are pro vided. In this case the number of wires which can be provided on the carrier is considerably higher than in the examples described before. If now the said wires are in the ordinary way connected to the standard in two parallel rows, these rows would be very high and therefore the matrix bars would be very long. To avoid this the wires are secured to the standard 70 in four parallel rows located one beside the other.

While in the examples so far described all the branches. of the frame are parallel to each other and to the line of set matrix bars, or nearly so, in the example shown in Figs. 6 and 7 only the branches located on the same side of the carrier are parallel to each other or nearly so, while the branches located on opposite sides are at an angle to each other. Therefore two groups of rows are formed, and the rows Z Z of the left hand group and the rows Z Z of the right hand group are respectively parallel to each other, or substantially so. The branches Z and Z and the branches Z and Z are respectively disposed at an angle to each other, so as to form V-shaped sectional frames. In this case the inner sectional frames Z, Z have nearly the same size as the outer ones Z Z so that the matrices can be distributed on the carrier in a determined way.

As appears from Fig. 7, the guide wires m of the outer frame Z Z are secured to the lower portion of the standard 0, while the guide wires n of the inner sectional frame are secured to the upper portion of the said standard.

The wires or ways are arranged in groups and these groups are disposed on opposite sides of the longitudinal center line of the frame, that is to say a line extending from the standard directly rearward to the rear bar of the rocking frame. The groups on one side of this line are balanced exactly by similar groups on the opposite side of the line. It is not necessary that groups on the same side of the longitudinal center line he alike or balance each other, but for each group on one side of the line there is preferably a corresponding group on the opposite side of the line.- The wires in the corresponding groups on opposite sides of the center line are alike in number and length and inclination so that the frame is nicely balanced. It is also to be noted that the guide wires at their rear ends are turned laterally more or less and are connected to the side bars of the rocking frame rather than to the rear bar thereof, this latter arrangement being the ordinary practice.

By my arrangement of the guide wires a much greater number of wires may be placed in a given size frame and a frame carrying the usual number of wires may be considerably smaller than when the wires are ar-- ranged in the usual way.

I claim herein as my invention:

1. A matrix carrier for a line casting machine comprising a standard, a carrier frame provided with side bars and with forwardly projecting arms or branches within said frame, a group of matrix supporting and guiding wires connected to each of the side bars of the frame, an independent group of wires connected to each of the forwardly extending arms of the frame the wires of each group being carried forwardly to a common vertical plane and continued in a common vertical plane to the standard.
