TYPOGRAPHICAL MACHINE.

Specification of Letters Patent.

Patented Aug. 3111, 1914.

Application filed January 24, 1913. Serial No. 743,913.

To all whom it may concern:

Be it known that 1, WILLIAM S. BALDWIN, citizen of the United States, residing at W0rcester in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Typographical Machines, of which the following is a specification, reference being to the accompanying drawing.

My invention relates to typographical machines, such as linotype machines of the general organization represented in Letters Patent of the United States, No. 436,532, to O. Mergenthaler, wherein circulating matrices are released from a magazine in the order in which their characters are to appearin print and then assembled in line, the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices thereafter returned through a distributing mechanism to the magazine from which they started.

More particularly,.it relates to the means for injecting the molten metal into the mold, and it is the aim of my invention to provide devices whereby these injecting means may be arrested at will, and this preferably by a manually-operable handle or lever within convenient reach of the operator.

Linotype machines have been provided in the past with automatic mechanism whereby the pump is prevented from acting in various contingencies, as for instance if the line of matrices be not assembled in close order and clamped tightly together between the confining jaws. Such mechanism is presented in Letters Patent of the United States to G. A. Bates, No. 659,865. In this and other similar constructions, the metalinjecting mechanism is normally locked against actuation, and is unlocked only in the event that the line be properly compacted between the jaws.

It is one of the principal purposes of my improvements to permit the locking of the metal-injecting mechanism, even after it has been unlocked in the manner indicated. This is desirable in many instances, as for example when the operator wishes to pre vent the casting of pi lines, or even to prevent squirts in the event that the automatic stop is not properly operating.

In the accompanying drawings, I have iad therein.

. shown my invention in preferred form and by way of example, and as applied to a linotype machine, but obviously many modifications and variations may be made therein, and 1n its mode of application, which will still be comprised within its spirit. Thus, it may be applied to any form of typographical machine comprising casting mecl1- anism, such as typecasters, etc., etc.

Generally speaking, I desire it to be understood that I do not limit myself to any speclfic form or embodiment, except in so far as such limitations are specified in the claims.

In the accompanying drawings: Figure 1 is a plan view, showing the pot, mold disk, pump-stop connections, etc., etc, with my invention applied thereto; Fig. 2 is a front View of a portion of the machine in the vicinity of the intermediate channel; and Fig. 3 is a rear view of the pot and the pump-stop devices.

The matrices are delivered to the assembler A, which is then elevated and the line transferred therefrom through the interme cliate channel B to the first elevator C, by which in turn it is presented to a mold, carried by the mold disk D, and wherein the slug is cast, the molten metal being supplied thereto from a pot E. The parts so far described, and their operation, are or may be substantially the same as those disclosed in the said Mergenthaler atent.

The metal-injecting means comprise the pump-plunger I? connected to the actuating lever G, the plunger and lever being held against operation by locking devices P, unless the line be properly compacted between the jaws, all as disclosed in the said Bates patent. As therein described, the locking devices P normally hold the lever G and plunger i against movement, and permit them to descend only when a proper matrix line acts to move the jaw. It is the aim of my invention to add devices whereby the parts may be locked at will, and preferably by a manual act of the operator, for the purposes previously mentioned.

In my preferred form, these stop devices comprise a stop arm H, pivotally connected to the frame of the pot- E, so as to swing therewith, and also capable of a movement relatively thereto to engage its upper end under the projecting block Gr carried by the lever G, in such manner as to prevent its w front ofthemachine and inconvenient proxin. "Vl'/"hen.the pot moves forward to coplication will suggest themselves to those construction and mode of operation, What I G, and serves to return the arm to its outdoWnWard movement and 7 the consequent ejection of the metal. A spring H normally holds the arm'Hout ofrthe path of the block Ward position after it has been operated.

For the purpose of shifting the arm H, any means atvvill.

suitable connections may beemployed, innthe form shown, these'c'ompi-ising the cord J connected thereto and passing over a'pulley K to the operating handle L, located at the imity to thefoperator'. a

--InFig. 1, the pot E is' shovvn in its retracted position, and-at this time the stop arm His similarly in inoperative relation to the'bloclcGr, as indicatedby full lines thereskilled in the art Without departure from its scope.

Having thus described my invention, its

claim and desire to secure by Letters Patent of'the United States, is as follows:

1; In a typographical machine compris- -f Copies of this patent may be obtained for five centsi ing casting niechanism, the oombiiiation of metal injecting means,. stop devices vcon trolled automatically for arresting their ac.

tuation, and separate and independent stop devices under the exclusive control [of the operator for arresting the actuation of 'said underthe exclusive controlgjof'the operator, and manually operable connections from 2. In a typographical machine "comprising cast-ingmechanism, the combinationof the ,pump lever, an automatic stop therefor, a :further adjustable stop for the pump levers said stop and extending to the" front of the machine in, proximitv to the key-board, a

whereby theaction of the pump lever may be instantly prevented at the Will of'th'e operator while seated at the keyboard,

3. In a typographical machine comprising casting mechanism, the combination of the pump-lever G, the automatic stop device P therefor, the pivoted stop-arm H under the exclusive control ofthe operator, the handle; L arranged in proximity: to the key-board,

andconnections therefrom to the arm 11'; whereby the operationofthe pump lever Gr may be instantly prevented atthe will of the operator Whileseated at the keyboard,
