TY'POGRAPHICAL CASTING-MACHINE.

Specification of Letters Patent.

DELL, a

type machines of the general character set forth in Letters Patent ofthe United States, No. 436,532, to O. Mergenthaler, wherein the slug or linotype is cast in a slotted mold and is then delivered therefrom by a reciprocating ejector blade, which advances through the moldv from the rear, forcing the slug before it through the trimming mechanism to the receiving galley at the front of the machine. The ejector blade is connected to the front end of a horizontally movable slide, the construction being such that it may be readily detached therefrom to permit the substitution of another of different dimensions.

In the commercial linotype machine, the ejector slide is mounted on a second slide which carries the mold wheel at its outer end. In order to effect certain adjustments and for various other purposes not necessary to state herein, it is frequently necessary to draw the ejector slide manually forward to bring. it to a convenient position for the desired manipulation. In the past, this result has been accomplished in a variety of ways. For example, in order to advance the blade to the required position, the operator has left his place at the machine and turned the actuating cam and connected parts by hand; or he has disconnected the link from the ejector lever by the removal of the con-- necting pin; or in another instance the ejector slide has been provided with a movable latch to permit its disconnectionfrom the link. In my present form, I provide improved means whereby the link may be readily connected to or disconnected from the actuating lev'er at will, the parts being so constructed and arranged as to prevent their accidental displacement both in operative and inoperative position.

In the accompanying drawing, I have shown my invention in preferred embodiment and by way of example, and as adaptresiding at In the accompanying drawing F igure 1 is a side elevation of the mold wheel, mold slide, ejector slide, and its actuating link and lever, having my improvement embodied therein; Fig. 2 is an enlarged detail, illustrating the improved latch in operative condition; Fig. 3 is a similar view of the latch in detached position; and Fig. 4 is a section on the line 4-4 of Fig. 2. a

The mold slide A carries the mold wheel B, and also the ejector slide 0, which is reciprocated with relation thereto by the actuating link D and ejector lever E in the usual manner, as in the ordinary commercial linotype machine, or as illustrated for instance in numerous Letters Patent of the United States, such as No. 945,609 to J. R. Rogers. The link D is connected to the lever E by the pin F mounted in the latter, and to permit the ready engagement and disengagement of the parts for the purposes previously indicated, I have provided the link with connecting means which are now to be described. The link D is formed at its rear end with the vertical notch D- to engage the pin F. The end of the link is also provided with the relatively movable latch 1 formed with the horizontal notch J which also engages the pin F, and whereby the link is securely held in relation thereto, when the parts are in their operative condition. The end of the link D is bifurcated, (see Fig. 4), and the latch G is located therein, it being pivotally mounted upon the transverse'pin H which passes through the longitudinal slot G, this arrangement permitting two movements of the latch with reference to the link, pivotally about the pin and also longitudinally to the extent permitted by the length of the slot.

The latch G is formed at its inner end with the inclined or beveled surface K, and the link D with the correspondingly inclined or beveled surface L, a spring M being also provided, connected at one end to the latch and at its other end to the link, in such manner that when the parts are inoperative condition I (see Fig. 2), the spring holds the two surfaces in contact and thereby prevents the accidental disengagement of the parts. At this time, the end of the link D is held against vertical displacement by the engagement of the horizontal slot J of the latch G with the pin F, and the end of the slot G isin close relation tothe pivotal pin H. This position of the parts continues until the latch G'is moved longitudinally (see Fig. 3), and the other end of the slot G is brought into relation to thepin H, at which time the disengagement of its notch J from the pin F and the separation of the surfaces K and L permits the pivotal movement of the latch, when the end of link D may be elevated to free its notch D from the pin F. The e ector slide C may now be moved at will for the purposes of blade substitution or otherwise.

It is to be noted that due to the combined longitud nal and pivotal movements of the latch with reference to the link, the parts when shifted either to operative or inoper-.

ative position, pass center and are then securely held in substantially the same manner as in the well-known jackknife joint. Moreover, the spring M acts to move the parts to their final position when manually started in either direction. For instance, if the latch be in the locking position, as shown in-Fig. 2, and if it be moved longitudinally and then slightly tilted upward, the spring immediately snaps it to the unlocking position, as shown in Fig. 3. Or if from the latter position the latch be tilted downward, the spring draws it home and restores it to the locking position.

As previously stated, I have shown my in vention only in preferred form and by way of example, but obviously many modifications and variations therein, as well as in its mode of application, will suggest themr I. Miss,

selves to those skilled in the art without departure from its scope.

Having thus described my invention, its construction and mode of operation, what I claim and desire to secure by Letters Patent of the United States, is as follows:

1. In a linotype machine, the combination of the ejector slide, its actuating lever, and the intermediate connecting link, the lever being provided with the pin F to engage the link randjche link. carrying the movable latch G- which engages beneath the pin F and thus serves to prevent the disengagement of the link from the pin.

2. In a linotype machine, the combination of the ejector slide, its actuating lever, and the intermediate connecting link, the lever being provided with the pin F to engage the link, and the linkcarrying the movable latch G formed with the slot J to straddle the pin and thus prevent the disengagement of the- .G formed with the horizontal slot J to en gage the pin.

4. In a linotype machine, the combination of the ejector slide C, link D, and actuating lever E, the said lever being provided with the pin F to engage the link, and the link being providedwith the pivotally and longitudinally movable latch G to engage said pm.

5. In a linotype machine, the combination of the ejector slide C, link D, and actuating lever E, the said lever being provided with the pin F, and the link being formed with the vertical slot D to engage the pin and provided with the longitudinally and pivotally movable latch G formed with the notch J to engage said pin.

6. In a linotype machine, the combination of the ejector slide C, link D, and actuating loved E, the said lever being provided with the pin F to engage the link, and the link being provided with the pivotally and longitudinally movable latch G to engage said pin, together with the spring M to hold the latch in both operative and inoperative position.

7. In a linotype machine, the combination of the ejector slide C, link D, and actuating lever E, the said lever being provided with the pin F, and the link D being notchcd at D to engage the pin and provided with the surface L, together with the longitudinally and pivotally movable latch G connected to the link and formed with the notch J to cngage the pin, and formed with the surface K to engage the surface L on the link, and thekspring M connected to said latch and lin 8.
