The invention is shown as applied to a casting box- which comprises a back I and an upright cylinder or core I3. The back is movable to 60 ward and from the cylinder, and the cylinder is 'stereotype,plataagainst it. The‘other end .of' thexlocking lever II is pro 50 vided with two-notches 4 and 6 for cooperation with a roller III which is mounted rotatably on a stud carried ~ by; the locking handle I5. This lever is pivoted toithe back by a stud I9. 1‘ .Referring now'to Fig- 1, the back I may be 55 considered as away from the cylinder,‘ but the -matrix bar'and clips are iiip‘roper ‘position for iocati-ng’the mat‘rix'befo're"the‘b'ack is' moved into casting position. The roller I4 is now located in the outside notch 4 of the lockinglever II. It 60 2 ' 2,137,190 will be understood that a similar arrangement is carried on the other side of theback.~v .In this position‘ there is a slight amount of clearance p 1.

Referring now to Figs. 2 and 5, it will be seen that a shaft I6 is carried in bearings on the matrix bar 2 and has secured to it a lever I1‘ and 15 pin arms I8. On the locking handle I5 is a cam , projection 20 which engages one end of the lever II in this position and, on account of the motion of the locking handle I; just described,irotates the mold is open.

These pins have conical ends so that they will‘go through the holes in the matrix and, as the holes are the same size as the pins‘, they will register the ma 30 trix perfectly and bring the matrix into the proper position for casting the ?rst plate. However, before the plate is cast, the locking handles l5 are opened to the position shown in Fig. 4.

After the ?rst plate is‘ cast the casting back of course is drawn away-fromlthe cylinder and the parts take the position'shown in Fig. 4, as 60 stated. Here the pins 2| -reengage in the holes of the matrix and any slight tendency of the matrix to move is corrected immediately after the casting operation by the insertion’of these conically pointed pins and the matrix is brought back to its original position or re-registered. Any number of castings may be made with this arrangement and the matrix is re-registered automatically after each casting and before the plate is removed.
