Specification ofLetters Patent.

Patented Dec. 10,1912.

' Application filed January 14, 1907. Serial No. 352,177.

To all whom it may concern:

Be it known that I, JoHN RAPHAEL Roenns,.of the borough of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Molds for Linotype-Machines, of which the following is a specification.

My invention relates to a universally adjustable mold for use in line-casting machines which are sold under the various trade marks Linotype, Typograph,

"Monoline,. &c., and represented,for ex ample, in Letters Patent of the United States to Mergenthaler, #557,000. In these machines a type metal slug or linotype, bearing on its edge the type characters to print a line, is cast in a slotted mold against a composed line of matrices presented momentarily to the face of the mold to form the type characters on.the slu iii the commercial use of the machines, it is necessary to change the length of the slugs according to the width of the page or column to be printed, and also necessary to change the thickness of the slugs according to the size of the type faces which are to appear thereon.

The first aim of my invention is to provide a self-contained mold in which the slot may be instantly varied in length, or in width, or in both, without the addition or removal of parts, and to this end it consists of the combination of relatively movable members forming the top, bottom and end walls of the slot, with means foradjusting and confining them.

The second part of the invention has in view the automatic opening and closing of the mold, and the movement of the mold from the casting position for the purpose of carrying the contained slug past the trimming knife, and for. presenting the trimmed slug to the ejecting devices, and to this end it consists in the novel manner of mounting themold so that it may be reciprocated lon-.

gitudinally and also moved facewise, as hereinafter described.

tudinally movable cap B, a vertical slide C may enter in order to cont-actwith the rear the line 5-5 of Fig. 1. Fig. 6 is a front elevation of the moldv in operative relation to the adjacent parts of the machine. Fig. 7 is a cross-section of the same on the line 77 of Fig. 6. Fig. 8 is a horizontal section on the line 88 of the preceding figures. Fig. 9 is a perspective view of the sliding support in which the mold travels. Fig. 10 is a perspectiveview of the slide or frame in which the mold is mounted.

Referring to Figs. 1' to 5 inclusive, it will be seen that the mold proper consists of the following principal members: A body portion A, an overlying vertically and longigforming one end of the mold-slot, and a horizontal slide .D forming the opposite end of the slot.

For the purpose of supporting the foregoing parts and holding 'them in their or frame E, such as shown in Fig. 10, having its front face recessed to receive the mold members, and also to receive a wedge F overlying the mold-cap. The body A is secured rigidly in the slide E, and the latter is provided in its rear face with an opening 6 through which the nose ofthe meltin pot face of the mold.

The upper surface of the body A is horizontal and forms the lower side of the moldslot or cell a. The under side of thecap B is also horizontal and forms the upper side of the mold-slot. The vertical slide or liner C is urged constantly upward by a springeseated beneath it, as shown in Figs. 1 and 3,

for the double purpose of maintaining an intimate contact between the slide and the mold-cap to close theend of the mold-slot, and of causing the slide to urge the cap upward. Theslide D, or liner which is arranged to move in intimate contact with the upper surface of the body A, is provided at its inner or left end with an upturned portion which is seated in a vertical slot in the cap B, a s ring (1 being interposed for. the purpose 0 urgin the cap upward. The

proper relations, I provide a strong slide Y In the drawings, Figure 1 is a front ele' 50 vation showing the principal parts. of my mold. Fig. 2 is a similar view of the parts adjusted to produce a slot of smaller size. Fig. 3 is a cross-section on the line 3-3 'of Fig. 1. Fig. 4 is a cross-section on the line 4-4. of Fig. 2. Fig. 5 is a cross-section -.on

wedge F is seated etween the upper side of the, cap B and the overlying portion of the sl de; or frame E. By moving the wedge endwise, the cap may be forced downward toward the body in order to reduce the height .of the slot a and the thickness of the slug produced-therein, and this withoutalfecting Q;

1 the length of the slot. As the cap moves vertically, the slide or liner C rises orfalls, maintaining its close contact therewith.

The slide or liner D, however, is without ing the cap B and slide D endwise, the effect being to change the distance between the slides C andD, and this without affecting the height of the slot or the thickness of the slug. From the foregoing it will be perceived that without attaching or detaching parts, the slot may be instantly varied in. length, or in height, to roduee a slug of any required length an thickness.

The parts may be adjusted in their vari- .ous positions by any suitable binding or locking devices, but I recommend for the purpose a bar G secured at its ends to the body by screws 9, so that when the latter are tightened, the bar will bind firmly against J the-face of the mold-cap and-wedge, as

shown in Figs. 1, 2 and 3 v The mold as a whole may be mounted and operated in any way which will admit of-its position which will permt the ejection of the slug. I prefer, however, to mount the mold so that it may slide to and from the casting position, and so that it will also have a forward and backward movement to and from the line of matrices. To this end I prdvide a frame or slide H, such as shown in'Fi 8, having two arms atright angles toeac other. One of these arms is pro- 40 vided with parallel'g uides h, adapted to receive theupper and lower edges of the moldsupporting slide E, so that the mold may be. moved endwise therein. This arm is also provided with a large opening it, through which the mouthof the pot mayenter, and with a slot 7%, through which the ejector blade may enter to deliver the slug from the mold after the latter has been moved from the casting position. At right angles to the mold-guide h, the frame H- has the guiding surfaces h arranged to move incorresponding guides in the main frame h. The last-named guides admit of the frame H being moved 5 whole, carrying the mold with it in a facewise direction, or in other words, in a direction to and from the matrices.

In practice it is desirable to provide for the slight automatic opening of the mold in order to relieve the pressure on the slug and permit of its easy ejection, and it is also desirable, in some cases, to provide for automatic elongation of the meld-slot to its maximum limit after each casting action to 5 the end that a single ejector-blade of makibeing moyed from the casting position to a 'ing portion of forward and backward as a mum width may be employed to deliver all 0 slugs regardless of their length.- With these ends in view, I combine with my mold, above described, mechanisms such as shown in Figs. 6, 7 and 8. The wedge F is provided at the left end with'a projection f, and as the mold is moved horizontally to and fro between the casting and ejecting positions, this projection f contacts alternately with the stationary stops 2' and 2'. As the mold moves to the left to'the ejecting position, the stop 2' arrests the wedge just before the mold completes its movement, so thatthe wedge is in effect moved to the right and caused to relieve the mold-cap B, permitting it to rise sufliciently to relieve the slug from pressure and friction.

' l/Vhen the mold is returned to the right from the ejecting to the casting position, the projection f encounters the stop 2', which 35 arrests the wedge wlfile the mold continues to advance to the right, the effect being to cause the wedge to force the mold-cap down to its original position.

The distance to which the cap is depressed, T

and the consequent thickness of the slug, depend upon the location of the stop 2', which is made adjustable to the right and left. The stops 2' and 4' are both formed upon or secured to a horizontal slide 1 guided in the frame and provided'with an operating handle 6?, carrying the .pivoted latch 2' arranged to engage in a notched plate 6*. This arrangement of parts admits of the stop a" being set in different positions so that the wedge will be adjusted and the mold-cap depressed to the exact position required, depending on the thickness of the slug to be produced.

In order to effect the longitudinal opening of the mold as it approaches the ejecting position,l provide a stationary stop K in position to encounter the left end of the moldcap 13 as the mold is moved to the left. This stop K arrests the horizontal advance of the cap B and liner D while the remainthe mold continues to advance, cui-rying the liner G away from the liner D, until the slot between them reaches its maximum length sui'l'icient to permit the 5 entrance of the widest ejector-bladehsed in the machine.

hen the mold returns to the casting position in front of the pot, it is necessary that the slot shall be again reduced to the predetermined length, and this is effected by mounting on the frame a stop L n position toencounter the right end of the cap B and arrest the samewith the liner D in the casting position while the remaining portions i of the mold, including the line C, continue to move to the right until the mold-slot is reduced to the proper length. The stop L is a slide guided in the fi ame and provided with a pivoted toothed operating handle Z for which it may be adjusted.

It will of course be understood that the liner D is in effect a shoulder carried by the mold-cap, and that the vertical sliding connection between the cap and liner is necessary only when the cap is adjustable vertically to vary the thickness of the slug.

The mold may be reciprocated in ahy suitable manner. I prefer to employ, as shown in Fig. 6, a pinion e mountedon the frame and en, 2;agin teeth in the lower edge of the mold frame v this pinion receiving motion in turn from the pinion a which is turned first in one direction and then in the other.

For the purpose of trimming the base of the slug prior to its ejection from the mold, I propose to employ a stationary knife M fixed in the frame in position to present its edge closely against the rear face of the mold, as shown in Fig. 8, so that as the mold is movedtoward the ejecting position, the base of they slug will be carried past the 'knife and trimmed thereby flush with the back of the mold.

It will of course be understood that any suitable means may be employed for reciprocating the mold; stop devices may be varied in form and arrangement at will, provided they have essentially the mode of action above described and generally the details may be varied within the limits of mechanical skill.

It will be observed that in my structure provision is made for automatically lengthening and shortening the mold-slot to any predetermined extent as the mold is carried to and fro, and that provision is also made for changing the width or height of the slot automatically and to any predetermined extent as the mold is moved to and fro, each of the adjustments being independent of the other.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. In a linotype mold and in combination, a body, a longitudinally movable cap overlying the same, a liner D having a transverse portion and alongitudinally extending portion. the latter bearing on the body and having a sliding action with the cap, a spring holding said liner in contact with the body, a liner C movable transversely across the mold slot, an actuating spring therefor, and a wedge F, capable of occupying changed relations with said parts to vary the width of the mold slot.

2. In a linotype mold, the combination of abody, the vertically and longitudinally movable cap overlying the body, the two liners C and D movable in directions at right angles toeach other, the liner D having a transverse port-ion and a longitudinally extending portion, springs holding said liners in operative positions, and a wedge acting to confine the cap in opposition to the springs.

In a linotype mold and in combination with a body, a cap member movable longitudinally relative thereto, a liner interposed between the cap and body and forming one end of the mold slot, said liner being pro vided with a transverse portion and with a longitudinal portion, the transverse portion being interlocked with the cap so that the liner as a whole will move-bodily with the cap longitudinally, and the longitudinal portion bearing on the body, said cap being movable transversely with reference to the liner, and means for closing the opposite end of the mold slot.

4. In a linotype mold and in combination with a body, a cap member movable lon tuclinally relative thereto, a liner carried li y the cap member and forming one end of the mold slot, means for closin the opposite. end of the mold slot, means for moving the mold to casting position, and a stop in position to be engaged by said liner when the mold is moved to casting position and acting to automatically close the mold.

5. In combination with the main frame, a frame H provided with a transversely extendingguide h mounted slidingly in the main frame to permit a facewise movement of the frame H, a mold-carrying slide mounted in the frame H and movable relatively thereto transversely of said facewisemovement, and a mold carried by'the slide and comprising relatively movable parts adapted to be actuated by the movement of said slide.

6. In combination with a frame H provided with two openings arranged side by side and adapted to receive respectively the mouth of a melting pot and an ejector blade, a mold carrying slide provided with an opening therethrough and mounted on the frame I-I so that it may be moved thereon to in operative relation to the opening in the frame through which the mouth of the melting pot is introduced, or to the opening in the frame through which the ejector blade is inserted.

7. In a linotype machine, the combination of a reciprocating mold comprising members also relatively to said members to actuate thet latter, said wedge having tending operating projection, two rearwardly extend ng horizontal stops fixed relatively to each other and with which said projection is adapted to respectively engage 1n the recip roosting movements of the mold, said stops being adustable in unison to diflferent posia forwardly ex? Witnesses:

tions, and a, forwardly extendingoperating handle connected with said stops for'adwsting them.

In testunony whereof I hereunto set'my 15 hand this twenty fourth day of December, 1906, in the presence of two attesting wit-v nesses.
