Abstract: 302,977. Wade, H., (Standard Compositor Akt.-Ges.). Sept. 23, 1927. No Patent granted (Sealing fee not paid). Assembling matrices. - Means for assembling and transferring a line of matrices to the mould comprises an assembling- abutment, a forward tramsferring- abutment, and an independently mounted rearward transferring- abutment, which brings the line into contact with the forward abutment, and then transfers it to the mould, the assembling- abutment being automatically withdrawn and returned to initial position. The matrices are assembled in a guide 2, Fig. 1, by a star-wheel 1 against a yielding assembling-abutment 3 mounted on a carriage 4, which is restrained by a lever 5 and a spring 6. The abutment is in the form of a downwardly projecting finger 3a, Fig. 8, on a shaft 8, on which is a two-armed lever 9, 12, Fig. 9, the arm 9 normally bearing on a stop 11 on the carriage. To the arm 12 of the lever is pivoted a stopplate 13, which has a slot to receive a pin on the shaft 8, and is pulled downwards by a spring 17. The edge of the stop-plate normally contacts with a stop 20, to prevent tilting of the finger 3a by the advancing matrices. When the completed matrix line is moved towards the mould, a lug 16 on the stop-plate is engaged by a fixed stop 28, Fig. 1, so that the plate is tilted into a position to clear the stop 20. Continued movement of the carriage 4 causes the stop-plate to swing the finger 3a upwardly out of the assembling-guide, so that the matrix line can pass below it. When the line has passed below the finger 3a, the latter is returned to the vertical position by the spring 17, and the carriage 4 is withdrawn to initial position. Upon depression of a line-key, the line is moved into the casting-carriage by the rearward transferring-abutment, which is in the form of a finger 21, Fig. 1, pivoted on a carriage 22, and normally held down by a spring pawl 23. The carriage 22 is operated by an endless chain 24, connected to it through a lost-motion device 27, which permits the pawl 23 to be released by a projection 25 on the chain, before the carriage is advanced. At the moment when the assembling-abutment is raised, the forward end of the line is engaged by the forward transferring-abutment, which is in the form of a finger 30, pivoted on a sliding carriage 31, controlled by a spring 35, which is attached at its right-hand end to a sliding rod passing through the spring. The spring passes through, and is engaged by, a threaded bore in a fixed lug, so that the right-hand part of the spring acts as a buffer for the carriage, when, in returning, it strikes the end of the sliding rod. Alternatively, the spring 35 may be in two parts. The finger 30 is normally held in vertical position by a pawl 37, Fig. 13. When the line reaches the casting-carriage, the abutmentcarriage 31 is locked in position by a pawl 39, Fig. 1, and the pawl 37 is swung away from the matrices by a spring 42. The motion of the chain 24 is then reversed, and the rearward abutment 21 is returned to initial position. As the casting-carriage descends, a stop restores the finger 30 to the vertical position, and trips the pawl 39, so that the forward abutment 30 is returned to initial position by its spring 35. A sliding pin 47, Fig. 16, in the casting-carriage is adapted to engage the forward end of the matrix line, when it has been transferred to the carriage. The pin is withdrawn by a lever 51 and a stop 49, when the carriage reaches the casting position, and may also, if necessary, be withdrawn, when the carriage reaches the distributor.
