SPECIFICATION forming part of Letters Patent No. 619,393, dated February 14, 1899.

T0 at whom it may concern.-

Be it known that I, WALTER S. OOE, of New York, (Brooklyn,) county of Kings, and State of New York, have invented a new and useful Improvement in Linotype-Machines, of which the following is a specification.

My invention relates to an improvement in the Mergenthaler linotype machine represented in Letters Patent of the United States No. 557,000, dated March 24, 1896, and also in improved form in Patent N 0.5463054, dated September 10, 1895, and now in general use in the printing-offices of the United States, the object being to prevent the accidental delivery of molten metal among the working parts of the machine, as hereinafter more fully explained.

In the commercial machine of the present daya pot containing a supply of molten metal is provided with a pump, by which the metal is delivered at intervals into the slotted mold and against the line of matrices composed temporarily against the face of the mold, the result being the production of a slug or linotype bearing on its edge, in relief, characters to produce one line of print. The mold is carried in a vertical wheel, which is in turn mounted on the arm of a horizontal movable support or slide,commonly known as a moldslide, which is in turn operated by a lever actuated by a cam. It is at times necessary to gain access to the rear face of the mold, and for this purpose the mold-operating lever is mounted as in Patent No. 546,054, so that it may be instantly disconnected from the slide in order to admit of the mold-wheel being drawn forward away from the meltingpot, so as to afford a Wide space between the pot and the mold. During this separation of the parts it is important that the action of the pump for delivering metal through the mouth of the pot shall be prevented, and it is to this end that the present improvement is directed; and it consists in a pump-locking mechanism connected with a device for throwing the mold-slide-operating lever into and out of action, so that when the mold-slide is disconnected and in position to be moved forward the pump is locked out of action.

I have shown my improvement as incorporated in the ordinary linotype of the present day; but it is to be understood that it may be modified in form and used in other analogous machines, provided no departure is made from the general mode of action herein described.

The drawings are limited to those operations of the machine which are necessary to an understanding of the invention. In all other respects the machine may be of ordinary construction.

Referring to the drawings, Figure 1 is a side elevation of the melting-pot, mold-wheel, pump-lever, and cooperating parts with my stop or locking device added thereto, the mold-slide being released. Fig. 2 is a similar View with the parts in operative position. Fig. 3 is a top plan view of the parts shown in the foregoing figure, the top of the mainframe standard being broken away to expose other parts to view. Figs. land 5 are elevations, looking from the rear of the machine toward the front, as indicated by the arrows in Figs. 1 and 2, showing, respectively, the positions of the parts when the mold-slide is unlocked and when it is locked.

Referring to the drawings, A represents a vertical mold-wheel carrying the mold a, having a slot therethrough from front to back, as shown.

Bis the horizontal movable mold-slide, situated in guides O in the main frame and having at its forward end a lateral arm, by which the journal of the mold-wheel is supported, as

shown.

D is a vertical cam-wheel acting on the roller F at the lower end of the lever E, which also carries a second roller G, adapted to enter a vertical notch H in the rear end of the mold-slide, so that the motion of the lever E, caused by the cam-wheel, will effect a backward and forward movement of the mold slide and wheel.

The leverE is suspended at its upper end by a pivot-pin I between the forward arms of the hand-lever J, supported at the middle point on the horizontal stud K, fixed to the main frame. When the rear end of the lever is depressed, its forward end rises, lifting the lever E and raising the roller G out of the notch H in the mold-slide B, thus releasing the slide, so that it'may be moved forward. When the lever J is again elevated, it lowers the parts to their operative positions, as shown in Fig. 2.

M is a horizontal spring-actuating pin mounted in the main frame in order to pass over or under the hand-lever, so as to hold the lever E in its operative or inoperative position, as demanded.

N represents the melting-pot, mounted behind the mold-Wheel, as usual, and provided on the rear side with a spring-supporting lever 0, through which it receives motion from the cam-wheel, unnecessary to describe.

P is the pump-lever, mounted at Q on a fixed horizontal pivot, connected at its forward end to the pump-plunger R and depressed by a spring-actuated rod S, bearing midway of its length.

All of the foregoing parts are constructed and arranged to operate in the usual manner, except that I now provide the rear end of the pump-lever P with an upwardly-extending arm T and provide the hand-lever J with a rearwardly-extending arm or shoulder U. These last-named parts are so proportioned and arranged that when the hand-lever J is depressed to lift the lever E and release the mold-slide the shoulder U is carried down in front of the arm T on the pump-lever, as shown in Fig. 1, and in this manner the pumplever is locked in its elevated and normal position, so that it is impossible for the pump to operate While the mold is moved forward. In this manner the accidental delivery of molten metal from the pot is positively prevented Whenever the mold-slide is unlocked.

What I claim as my invention is- 1. As an improvement in linotype-machines, the combination of a pump-locking device and a mold-slide-operating mechanism acting to prevent the action of the pump when the mold-slide is released.

2. In a linotype-machine, the combination of a pump-lever and alever-eontrolling moldslide-operating device, the last-named lever arranged to lock the first, substantially as described.

In testimony whereof I hereunto set my hand, this 30th day of November, 1898, in the presence of two attesting Witnesses.
