DISTRIBUTING APPARATUS FOR MATRICES 0F TYPE-CASTING- MACI-IINES AND THE LIKE.

Application filed January 7', 1924. Serial No. 684,791.

To all whom it may concern:

Be it known that I, CLARENCE H. Cnow- ELL, a citizen of the United States, residing at Fort Worth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Distributing Apparatus for Matrices of Type- Casting Machines and the like, of which the following is a specification.

My invention relates to equipment for type-casting machines which employ character matrices for molding type bars and thereafter are elevated and distributed to the matrix magazines; and the object is to provide means for elevating the matrices to and on the distributer bar without making use of the combination teeth which control the delivery of the matrices to the magazine channels. The advantage of such equipment is that the combination teeth are not used and mutilated during transportation before they reach the distributer bar. Another object is to provide the elevating and transporting devices with selective means for preventing the choking of the magazine channels with duplicate or other matrices. Other objects and advantages will be fully explained inthe following description and the invention more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application.

Fig. 1 is a side elevation of a second elevator bar and distributer box bar. Fig. 2 is an end elevation of the same, showing a matrix applied thereto. Fig. 3 is an end elevation of a distributer box bar with the adjustable bar point applied thereto. Fig. l is a broken plan view of the distributor box bar with the adjustable bar point applied thereto. Fig. 5 is a broken plan View of the distributer box bar, showing the rectangular slot or cut-out for the adjustable bar point. Fig. 6 is an end elevation of the distributer box bar, showing the rectangular slot for adjustable bar point and showing the bar point in dotted outline and showing the relative position of the retaining screw. Fig. 7 is a side elevation of the bar point. Fig. 8 is an end elevation of the same.

Similar characters of reference are used to indicate the same parts throughout the several views.

In the linotype art, means have been provided for elevating matrices and delivering the same to what is known in the art as a second elevator bar. The second elevator bar delivers the matrices to a distributer box bar, and the distributer box bar delivers the matrices to the distributor bar which has channels or grooves in the sides which co-operate with the combination teeth of the matrices in assorting the matrices for the proper magazine channels. The former construction of the second elevator bar and the distributor box bar with the channels on the sides effected rapid wear of the matrices and the. matrices were soon rendered worthless and new matrices had to be prepared. I have provided improvements in the second elevator bar and in the distributer box bar which will avoid the wear on the combination teeth of the matrices so that the life of the matrices is prolonged.

The improved second elevator bar 1 is provided with the usual means on the upper part thereof for mounting the bar on the machine. The bar 1 has smooth inclined sides 2 instead of channeled sides as heretofore made. The bar 1 is provided with means for supporting the matrices as they are moved along towards the distributor box bar. The inclined sides 2 extend down to a fiat strip or shank portion 3 and a head 4 is formed on the bottom of the shank portion 3 and the head 4 is approximately cylindrical in form. The distributor box bar 5 ispro-vided with similar sides 2, shank portion 3, and bead 4.

Improved matrices 7 are provided with approximately cylindrical openings 6 which are connected by restricted portions for making connection with the usual V-shaped openings which are provided with the combination. The opening 6 will take the friction and support off of the combination teeth of the matrices. The matrices will be pushed along on the beads at. 011 operation, after the type bar is cast, the matrices and space bands (not shown) are elevated by the first elevator (not shown) to the second elevator and are forced from the first elevator on the second elevator bar 1 into engagement with the bead 4. The second elevator is then raised for delivering the matrices to the distributor box bar 5 and the matrices are moved to the bar 5.by the usual pusher. The corresponding parts of bar 5 are similar to the parts 2, 3, and 4 of bar 1.

The matrices are moved by the pusher (not shown) to the distributer bar which forms no part of the improvements herein. The space bands may be provided with the same openings 6 and be handled in the same manner as the matrices until they are delivered to the space band box. The distribute-r box bar is provided with an adjustable bar point 8 for proper selection of the matrices so that only one matrix can pass at a time. The bar point 8 enters a groove 9 in the thicker matrices as each matrix is to be delivered to the distributer bar and in case of matrices too thin for a groove 9, only one matrix can pass at a time because the bar point 8 pro ects so far that only thin matrix can pass.

The difierent bars herein mentioned are all transfer bars and are used for handling matrices. The distributor box bar 5 and the second elevator bar 1, having smooth inclines and the heads 4; prevent the hammering and mutilating of. the combination teeth of the matrices and thus effect a. saving in matrices as well as making the handling or moving of the matrices more easily accomplished and more accurately distributed.

The improved bar point 8 is adjustably mounted in the end of the 'distributer box bar 5. The bar 5 has a rectangular recess 10 in the end and the bar 8 has a shank 11 has a portion thereof approximately square in cross-section which projects into the recess 10. A screw 12 is screwed down through the upper part of the bar 5 and clamps the shank 11 in the recess 10. The shank 11 can be projected more or less into the recess 10 and be clamped at any point of adjustment.

As a part of the distributing mechanism of this invention, matrices of special make are necessary. Such matrix shown in Fig. 2 and is provided with an approximately cylindrical opening 6 which is adapted to engage the heads 4: so that all the matrices can be moved along on the beads 4 when the matrices are to be restored to the matrix magazines.

What I claim, is,-

1. In a type-c: stint machine provided with a. distributer box bar having a socket therein; an adjustable bar point having' a shank projected into said socket and a screw for clamping said shank in said socket.

2. In a type-casting machine provided with a distributer box bar having a socket therein; an adjustable bar point having a shank projected into said socket, said shank being relatively thicker than the bar point, and a screw for clamping said shank in said socket.

In testimonv whereof, I set my hand, this 2nd day of January, 1924.

CLARENCE H. CROVELL.
