Application filed April 30, 1914. Serial No. 835,423.

To all whom it may concern:

Be it known that I, LEGRAND FRIEL, a citizen of the United States, residing at the city of Los Angeles, in the county of Los Angeles and State of California, have in vented new and useful Improvements in Printing-Matrices.

My invention relates to polygonal matrices having four or more casting edges which may be distributed into magazines in which the matrix will always be in the same relative position and the object thereof is to provide such matrices.

I accomplish this object by the mechanism described herein and illustrated in the accompanying drawings forming a part of this application in which;

Figure 1 is a perspective View of a matrix embodying my preferred form. V

Fig. 2 is a side elevation of a line of matrices elevated to the turning cylinder, a side elevation of the turning cylinder and a part of the distributing screws.

Fig. 3 is an end elevation of the turning cylinder and a matrix therein.

Fig. 4 is a development of the tracks in the turning cylinder.

Fig. 5 is a perspective view of another form of matrix.

Fig. 6 is a side elevation of the outer end of the lifting lever and a side elevation of the turning track.

Fig. 7 is a development of the turning track.

Fig. 8 is an enlarged detail of the turning track.

Fig. 9 is a side elevation of the turning track and of the master track and a fragment of the distributing track.

Fig. 10 is an end elevation of the lifting rod with a matrix thereon.

In the drawings 15 is a square matrix of my preferred form having four casting edges.

' Other polygonal forms of matrix may be used. In the use of my matrice sometimes the top casting edge of one matrix and the side edges of others and the bottom edge of others will be used in the same line. It is necessary to the best use of my matrices that the matrix shall always occupy the same relative position in the magazine and shall be susceptible of distribution to its proper magazine to occupy therein the same relative position on every occasion of use and distribution. To'accomplisnthis result I have provided a matrix with a central hole 16 in which the outer end 17 of the lifting lever 18 is received when the matrices are in the casting box (not shown). This lever by suitable mechanism (not shown), lifts the matrices out of the casting box and positions them against stop track 19 in register with the open end of turning cylinder 20 in the inner surface of which there are as many turning tracks as there are casting edges on the matrix. When the line of matrices are brought into register with the opening through the turning cylinder pushing lever 21 is operated by suitable mechanism, not shown, to push the matrices off the lifting lever and through the turning cylinder. The matrix has a portion of its edges of a configuration to fit the interior walls of the cylinder. Where a square matrix is used three of the corners are cut off and grooves 22, 23, 24 and 25 are provided in the interior wall of the turning cylinder into one of which the uncut corner 26 of the matrix is received. This uncut corner forms a turning lug on the matrix adjacent to the selection notches 27 which are the same in construction and use as the selection notches on the matrices of the Mergenthaler linotype matrices. In other forms of matrices the turning lug would be appropriately formed adjacent to the selectibn notches. It will be observed one of the tracks in the turning cylinder is straight and the others come into'the straight track. In a line of matrices brought into register with the turning cylinder the turning lugs of some of the matrices as they enter the turning cylinder will be received in one of the turning tracks and other lugs in other of the turning tracks and as the matrices are pushed through the cylinder they are turned by the lugs and tracks so that they pass out of the cylinder in the straight track thus bringing all the selection notches into register. As the matrices pass out of the turning cylinder they are lifted by rod 28 operated by suitable mechanism (not shown) into the sorting mechanism of the usual Mergenthaler type of which screws 29 only are shown. The sorting mechanism delivers the matrices each into its proper magazine, not shown. In Fig. 5 I have shown another form of matrix in which the turning lug 30 projects into the circular hole in the center of the matrix. When .this form of matrix is used the outer end 31 of the lifting lever is provided with as many longitudinal grooves 32 as there are casting edges in the matrix and the turning lug is received in any groove. The lifting lever elevates the matrices to a turning rod 33 provided With a straight groove 34 extending the Whole length of the rod and as many turning grooves 35 as there are casting edges less one. These turning grooves terminate in the straight groove and are provided With spring gates 86 at the straight groove Which gates permit a turning lug to pass into the straight groove and prevent the lug from returning into the turning groove. The entrance ends of these turning grooves are so located that as the matrices are pushed ofl the lifting lever the lug of each matrix enters either the straight groove or a turning groove and as they pass along the turning track the matrices are all turned With the turning lug of each in the straight groove. The straight groove is of sufficient length to receive all the lugs of a line of matrices beyond the junction of the turning grooves With the straight groove. After all the lugs of the matrices are in the straight groove of the turning track the pushing lever and lifting lever move away from the turning track and a master track 37 is brought into register with the selection notches of the matrices. A retractive lever 38 then pushes the matrices back along the turning rod and off the same, onto and off the master track and into engagement With a sorting mechanism of the Mergenthaler sorting mechanism type, not shown, which delivers each matrix into its proper maga' zlne.

Having described my invention What I claim is:

1. A matrix having a plurality of casting edges and selection notches in the edge and a central transverse hole: and a turning lug.

2. A matrix provided With casting edges and selecting notches and a turning lug in the edge and a central hole.

In Witness that I claim the foregoing I have hereunto subscribed my name this 16 day of April, 1914.

LE GRAND FRIEL.
