LINE-CASTIHG MACHINE.

Specification of Letters Patent.

T 0 all whom it may concern Be it known that l, lVILLIAM E. Bnu'rnaiz, a citizen of the United States, residing at 1 Brooklyn, in the county of Kings and State each line of matrices inv an endwise direction when presented to the mold for the casting of a line of type.

In machines of this class, it is often dcsirable to cast a slug or line. without type faces or characters thereon, and heretofore such. an operation has been accomplished usually by setting up a line of blank matrices or so-called quads. This result, hot ever, can also be obtained by bringing together and completely closing the vise jaws, the adjacent side of the. movable "jaw then closing the mold opening.

The primary object of the present invention is to provide means for holding to ether the vise jawsfor the casting of a blan I line,-

thereby avoiding the necessity of setting up quads or blank matrices, and this invention also provides automatically for the un1ocking or release of the metal feed pump in those cases where the pump is provided with a lock to control its operation.

To these ends the invention consists in certain improvements, and combinations and arrangements of parts, all as will be hereinafter more fully described, the novel features being pointed out particularly in the claims at the end of the specification.

In the accompanying drawings -F1gure 1 is a front view of the casting mechanism of a machine of the linotype )class embodying the present invention; Fig. represents a top plan view, partly in section, ofthe structure shown. in Fig. 1; Fig. 3 is a rear elevation, partly in section. of the construction as shown in Figs. 1 and 2, the mold wheel and crucible or metal pot being re- Patented Sept. "2, 1915.

Application filed January 29, 1913. Serial No. 71'4;3,186.

shbwn and will be described hs applied to machines of the well known l'notypc class, although. it is to he understood that the invention is not restricted necessarily to machines of this particular type or to the precise construction shown, as equivalent constructions may be used to accomplish the same result and such structures Will be included within the terms of the claims at the end of the specification. l

In the present instance each line of matrices is confined and held in an end/wise direction when presented to the mold by the

vise jaws

1 and 2, the right-hand jaw 1. iceinp; usually termed thefixcd jaw in view of the fact that it is eithegr fixed rigidly in position or has a very limited motion for the purpose of locking and unloclcing the metal supply or feed pump, while the letthand jaw 22 is commonly termed themovable jaw for the reason that it is adapted to be adjusted or set in difl'ercnt positions, according to the'varying lengths of the lines of matrices to be confined between the two jaws.- The mold 3 may be of the usual construction, providing an opening or slot 4 into which the metal is forced through the orifices 5 formed in the mouth-piece of the spout, the latter forming part of the crucible or metal pot 6. a I

In the usual operation of machines of this class, each line'of matrices is brought into a position between the opposed jaws by a slide 7 commonly termed the first elevator,

this elevator being movable vertically and crucible with its metal supply pump, the

spout. and the mouth-piece having the orifices 5 thercin'may be of the construction commonlyused'ybr of, any other'desired con- StI'llCi310l1.-' Usually, the metal supply pump is operated. at appropriate intervals to fdrce metal into the mold to cast a by an arm 9, eachdescending movement of aid arm operating the pump to supplya charge of-metal in the usualway,

Most linotype machines employ a safety lock to prevent operation of, the pump to supplymetal I, except at the proper time. The lock 10. shown in the present instance is pivoted to'a suitable stationary part of the frame at 11 and normally occupies a position beneath the lock or projection 12 on the arm 9 under the influence of a spring 18. Where a safety lock for the pump is employed, theyrighthand vise jaw 1 is capable of a limited movement, and such movement is produced by the expansion of the usual wedge Spacers during the justifying I of the line of/matrices. In the construction shown, this vise jaw -1 is adapted to be forced against a stop or set-screw 14 carried by a lever 15, the latter being pivoted at 16 on a suitable stationary part of the frame and its opposite end cooperates with the lock 10 whereby forcing of the vise jaw 1 against the stop 14 will rock the lever 15 in a direction to move the lock 10 clear of the locking projection 12, thereby permitting operation of the metal supply pump. Normally, however, the vise jaw 1 will not influence the lever 15 and hence the lock 10 will be in a position to prevent operation of the ump.

Wit fisuoh a construction, when it is desired to cast a blank line or slug without matrices,,it is not only necessary to move the vise jaw fil up against the jaw 1, but it is also necessary that the jaw 2 must exert at the proper time suflicient pressure on the jaw 1 to operate the lever 15 and thereby unlock the pump. It is diflicult and dangerous for the operator to exert such pressure with the fingers during the casting operation, and according to the present invention automatic means is provided for accomplishing this result.- Preferably, the justificr mechanism is utilized in carrying out the present invention, the justifier mechanism employing usually vertically movable rods 17 which in machines of this class are generally lifted automatically by spring pressure and they are pivotally connected at their upper ends to a justifier bar 18, this bar serving in the usual operation of the machine with matrices toforce up the wedge spacers and thereby justify the line. According to the present invention, no matrices or'spacers aroused, but the motion of the justifier mechanism is utilized to, force the movable jaw 2 against the jaw 1 with suiiicientpressure to unlock the metal pump.

To enable the justifier mechanism to per- -for1n this function, it is provided in the present instance with a cam or wedge 19 which may be fixed to one of therods 17 and this wedge is adapted to cooperate with a suitable part ofthe movable jaw 2, the wedge in the present instance cooperating with the right-hand wall of an aperture 20 which latter is, formed in the slide 21 to which the jaw 12 is attached. The dot-anddash lines in Fig. 3 represent ,a setting of the aperture'QO,thereby forcing the slide 21 and the jaw 2 attached thereto against the vise. jaw 1 and locking the two vise jaws in direct engagement and also forcing the jaw 1 against the stop onset-screw 14 on the pump-controlling lever 15. The pump is then ,unlocked and may operate to inject a supply of metal into the mold to cast the blank line or sing, this being accomplished ,while the vise jaws are held or locked securely together and hence the escape of molten metal between them is avoided.

I claim as my invention t 1. In a machine of the linotype class, the combination of a mold, fixed and movable vise jaws arranged in front of the mold, means for adjusting the movable jaw against the fixed jaw. a justifier arranged normally under the jaws to expand'wcdged spacers, anda head arranged on the justifier to engage the movable jaw to force and lock the same against the fixed jaw during the casting operation.

In a machine of the linotype class, the combination of a mold, a metal supply pump, therefor having means for releasing the same, fixed and movable vise jaws, and means for forcing the movable jaw directly against the fixed aw to close the opening in the mold and to operate the pump releasing means.

3. In a machine of the linotype class, the combination of a mold, a pair of vise jaws adapted to confine a line-of matrices between them and capable of being brought together into direct contact, justifier mechanism for expanding the spacers in a line of matrices, and means operative automatically by the justifier mechanism for forcing oneof said jaws against the other when the same are brought together without, matrices between them.
