SPECIFICATION forming part of Letters Patent No. 563,643, dated July 7, 1896.

Application filed December 28, 1892. Serial No. 456,559. (No modehl To all whom it may concern:

Be it known that we, ERNST BERTRAM and ERNST SANDERSpitizens of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Linotype-Machines and we do declare the follow in g to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to the class of machines known as linotype, of which the Mergenthaler machine, substantially as shown in Patent No. 436,501, granted September 16, 1890, is a type, although the said invention is equally applicable to the machine known as the Rogers 'lypograph, and, in fact, to all those whose function it is to cast a line stereotype, otherwise known as a linotype or type-bar.

The object of the present invention is to provide means, in connection with and under the control of the justification mechanism whereby the casting operation is prevented whenever the line of matrices in front of the mold is not completely filled out after the justifyin g operation. has been completed-that is to say, after the double-wedge spaces between the matrices have been spread laterally to their utmost extent and there still remain gaps or crevices, however slight, between any two matrices, or between the spaces and the matrices, into which gaps the molten metal would flow to form fins were the pump to act under such conditions. For this purpose adevice embodying our invention in its preferred form embraces alocking device or catch, such as a locking-bolt, adapted to be operated to stop or look the plunger of the metal-pump, preferably by being projected outwardly u nder the pump-lever of the metalpot (from which the molten metal is injected into the linotype-mold) whenever the justification-lever has moved the full extent of its stroke. It never makes a stroke when the mold contains a sulficient number of matrices, inasmuch as under such conditions the double wedges against which the-justification-lever acts, would be expanded laterally to such an extent as to arrest the lever be fore it has completed its stroke, as will be readily understood by those familiar with these machines. lVe provide the j ustilication lever for this purpose with an arm or shelf, which when the lever makes a full stroke bears against and rocks another lever, which in turn is connected with a bell'crank lever suitably connected to the pump-lever lockbolt.

Our invention also embraces an alarm,which may be of any well-known or suitable form, and which is so connected with the casting mechanism that it will sound to n otify the operator that no line has been cast; and my invention embraces such further means, combinations of parts, and features as will be hereinafter more particularly pointed out in the claims.

In the drawings accompanying this specification, Figure 1 is a diagram showing the relation of the justification mechanism to the linotype-casting mechanism and to the pumplever-stopping mechanism, interposed between the two in the preferred embodiment of our invention 5 Fig. 2,a side elevation of the said pump-lever-stoppi11g mechanism and so much of the adjacent mechanism as necessary to show its operation; Fig. 8, a front eleva tion, partly in section, of the same; Fig. 4:, a detail view of the interior of the alarm-bell and its immediate mechanism; Fig. 5, a detail sectional view of the pump-lever-locking bolt, and Fig. 6 a top sectional view of the conncctingmechanism between the alarm and the locking-bolt.

In the drawings, A represents the metalpot, from which the molten metal is injected into the linotypemold through the nozzle (a by the depression of the piston or plunger a, which, as shown, is connected with the pumplever B for this purpose. The pump-lever B is actuated by the pump-spring rod O, which at the moment of casting is yield ingly forced downwardly upon the same by the compression of the pump-spring 0, bearing upon the washer c on the pump-spring rod, as in the aforesaid Mergenthaler machine. For the purpose of preventing the pump-spring rod C from slipping off from the pump-lever E the latteris provided with an enlargement b, v

- having a socket in its top, which is engaged by the end of the pump-spring rod C.

D represents the justification-lever, which at the proper time is by well-known mechanchines now in use.

The mechanism thus far described is old and embodied in one class of linotype-1nae will now proceed. to describe that part ofthe mechanism which embodies our invention in its preferred form.

I By referring to Figs. 1, 2, and 3 it will be noted that the justification-lever D is pro- I vided at its forward end, which rises when the said lever makes its stroke for justifying, with a depending arm or rod E, which arm is provided with a horizontal lug or shelf 6. In the path of said lug e is arranged the end of a lever F, fulcrumed at f in any fixed part of the machine; and this lever F is by intermediate mechanism connected w-ith a looking device or catch in the form of a lock-bolt G, guided in a suitable casing in a fixed part of the machine, and so arranged that when it is thrust outwardly, as indicated in dotted lines in Fig. 3, it will lie under the pumplever and thus lock the same.

The mechanism which we prefer to'employ for this purpose consists, essentially, in a pit man H, connecting the arm of lever F, opposite to the horizontal shelf e, with a bellcrank I, pivoted at i and connected by a link i" with a stud g, projecting laterally through a slot 9' in the casing, in which the lock-bolt works. In order to retain the forward end entirely within the casing when the same is not positively thrust outwardly by the mechanism just described, we provide the same with an automatic returning mechanism, preferably in the form of a spring 9 encircling the bolt G, which bears against a rear shoulder g on the lock-bolt, and. a forward interior shoulder g in an enlarged portion of the easing, adapted to receive the spring 9 In order to prevent the stud g from being loosened and the mechanism depending thereon from becoming disarranged or injured' by the said studs striking against the sides of the slot g,we make said slot somewhat longer than the stroke of said stud and so that the same will not strike the end walls of the said slot at either stroke, and we preferably arrange the casting or other fixed part K of the machine, on which'the alarm, to be hereinafter described may be mounted, in such a position that the rear end of the bolt G is arrested by and abuts against said casing when the lockin g mechanism is not in operation, as shown in. full lines in Fig. 5.

In order to be able to accurately adjust the precise point in its upward stroke when the lug e will act upon the lock-bolt G, through the intermediate mechanism, we provide the lever F with a stroke-adjusting screw f. against whose end the lug e bears when the justification-lever makes a full stroke.

In order to notify the operator that the pump-lever has been locked, and hence that noline has been oast,.we connect an alarm L with the pump-lever-locking mechanism. which alarm may be of any suitable or desired form, and may consist of a gong, as shown. adapted to be struck by a hammer 1, whose tripping-lever Z" is connectedwith the stud 5/ on the lock-bolt G by, a connecting-rod i which connecting-rod may be provided at its end with two adjustable nuts Z betweenwhich' the tail of the tripping-lever Z is-held.

The mechanism thus described operates as follows: When the justification-lever D makesits stroke to justify or fill out the line under ordinarycircumstances, that is to say.

when the line of matricesand spaces in front of the mold iscaused to completely and compactly close the mold, the said justification 3 j ustification-lever can make a full stroke, and

thus strikes the lever F through the medium of the adj Listing-screw f on the same, and by drawing down the pitman H tilts the bellcrank I, which in turn thrusts the lock-bolt G out of its casing directly under the pumplever B, as shown in dotted lines in Fig. 3. The pump-lever B is thus locked and no metal can be injected into the mold. At the same time the alarm L is sounded by virtue'of the connecting-rod Z ,which, through the intermediate mechanism-described, trips the hammer of the alarm, thereby notifying the operator that no line has been cast. As soon as the justification-lever returns to its position of rest and the locking mechanism is released,

his work as the same proceeds and without first casting such linotypes and'necessitating their inspection.

\Vhile we consider the mechanism above described the best embodimentof our invention it is manifest that the same may be modified in many ways without departing from the scope and spirit of said invention. Thus, for example, instead of the locking-bolt, other looking or stopping devices or catches may be employed. It is to be observed, however, that all that is essential is to lock, stop, or arrest the pump piston or plunger a, through the action of the justification mechanism, and that therefore any device under the control of the justification mechanism which will arrest the said pump will be an equivalent of our locking-bolt and its arrangement, which has only been shown and described as an illustration of our invention.
