Patented May 2'7, 1913.

A slug forming mold, as used in linotype and similar machines, comprises a base member 2, and a cap member 3 having-substantially parallel opposed

mold faces

4 and 5 respectively. These two parts when in place .in the slug casting machine are; pressed firmly together in their relative ositions, as shown in Fig. 1, by somesuita le clamping means, but in-the'dr'awings I' have chosen to illustrate the two parts as being held clamped together by means ofstud upperends by means of which the cap is clamped in place. I hold-the'cap member above the base member a-suflicient distance to produce a slug of the desired thickness length and height to produce a slug of the deslred dimensions The height of the slot is regulated by the thickness of the liners,

bolts 6 which rise from the opposite ends of i the base projecting through slots ,7 in the ends of the cap and having nuts 8 on their different pairs or sets of liners being used for producing slugs of the different thicknes'ses. It is a common practice to use a linerof afixed length at one endof the 'various devices with which the mold operates in the roduction of slugs Wlll. cooperate..therewit properly and without damage to themselves or the mold. The liner 9 is thus properly positioned by means of the transverse tongue 14 on its lower side, which enters the groove 15 in the base member 2, and the stop pin or post 16 carried by the base, which engages the end of the transverse slot 17. The. liner 10 comprises a fixed member 18 and the adjustable member 19,

.and the fixed member 18 is properly posi-' tioned within the mold in a manner similar to that in which the liner 9 is positioned,

that is to say, it is provided on its under face with a transverse tongue 20 which enters a transverse groove 21 in the base and it is provided'with a transverse slot 22, the forward end of which engages with a -stop pin or post 23 carried by the base.

In the preferred form of my invention, as illustrated in Figs. 2 and 3, the two

members

18 and 19 of the adjustable liner 10 are each what might be termed L shaped in plan view; the base portions 24; and 25 respectively of the two members reachmg across the mold and forming the ends of i the liner, and the

stem ortions

26 and 27 respectivel thereof over apping and forming the mi dle portion of the liner. The two parts are so formed that when the stem 27 of the adjustable part 19 is brought into. contact with the stem 26 of the stationary.

part 18, the adjustable part is properl alined in relation to the parts of the mol The inner edge 28 of the stem of the fixed liner is substantial y parallel with therear edge 29, which coincides with,

the rear face of the mold. The stem portion 27 of the adjustable portion 19 of the liner 10 is substantially longitudinally parallel and of a width to fill the mold between the forward edge 28 of the fixed portion 18'and the front face of the mold, consequently when the adjustable portion 19 is placed in the mold with its rear edge 30 in contact with the forward edge 28 of the fixed part 18, it is properly alined with'the mold' and its forward edge 31 coincides with the front face of the mold. As illustrated in Fig. 4 I sometimes make these contacting edges of the two parts smooth or straight and in this instance" their function is to properly aline the adjustable portion of the ortion 26 i liner with the mold, and in order to hold the two parts in their proper relative position once they have been placed, I rovide the baseportion 25 of the adjustab e liner with a dove-tailed opening 32 and I provide the opposed end 33 of the fixed part 18 with a similar dove-tailed opening 34. The space between these two portions of the liner 10, together with the dove-

tailed openin

32 and 34 is filled with molten metal the first time that the mold is used for casting a slug. This metal solidifies forming a spacer 35 which serves to retain the twomembers in proper relation to each other, it being understood that the two liners 9 and 10 are firmly clamped between the base and ca before a cast is made. The inner en s 11 and 12 respectively of the liner formthe ends of the slug slot and the position of the end 12 determines the length of the slug. In the process of casting slugs, by

means of the mold, more or'less pressure is exerted which tends to force the adjustable ortion19 of the liner 10 backward or away rom the fixed liner 9 and. so destroy the ac curacy of its adjustment. This retrograde movement is opposed and prevented by the soft metal spacer 35 under ordinary circumstances, but -I prefer to so form the contacting edges of the two parts of the adjustable liner 10 as to increase the resistance of the adjustable portion 19 to this movement. As

shown in Figs. 2 and 3, I provide contacting edges of the

parts

18 and 19 with what 'might be termed complementary ratchet teeth 38 which present a plurality of shoulders 39 which 0 pose the pressure that tends to move the a ustable part 19 longitudinally in the mold. It will at once be understood that these teeth may be formed of many different shapes without departing from the spirit of my invention, provided the general line of the contacting surfaces of the two parts are maintained parallel with the front and rear faces of the mold so that the adjustable portion 19 will be properly alined and positioned in the mold 1 when placed at different points to produce slugs of different lengths. It will now be seen that the adjustable part '19 .can be moved out of contact with the stationary part 18 b a very slight movement to the front of t e mold and when it is freed from the fixed part 18 it can be moved longitudi-' adjustable member and definitely resisting the pressure which tends to move it out of its desired position. A further advantage of this form of liner is that the teeth 38 can be made of such dimensions that the various adjustments of the member 19 will produce slugs of certain definite lengths, the lengths of these slugs being those which are commonly used in the printing art. I provide this preferred form of liner with the

dovetailed openings

32 and 34 similar to those described and which perform the same function. \Vhen placing the liners in the mold the cap is raised suflicient to permit the parts 9 and 18 to be slid horizontally into place between the opposed faces of the mold, the cap being only raised sufiiciently above the base to allow these parts to be freely moved between the opposed faces to this position, then the adjustable part 19 of the liner 10 can be freely moved horizontally between the faces to adjust the length of the slug slot.

In the preferred form of the invention the part 19 can be moved forward sufiicient to disengage the opposed teeth on the

members

18 and 19 and then it can be freely moved horizontally from and toward the fixed liner 9. In the forms of the invention illustrated in Figs. 4, 5, and 7 the adjustable parts can be freely moved from and toward the fixed liner 9 without a preliminary transverse movement as there are no opposed teeth in these forms to be'disengaged.

The two parts of the adjustable liner having been placed in their desired position to produce a slug of the proper length and the cap member of the mold having been clamped upon the liner by the clamping devices and a cast having been made, the two parts are thereafter held definitely in their adjusted position by the spacer 35 which is cast within the space between the fixed and adjustable parts of the liner 10 at the time the first slug is cast.

In the form of the invention illustrated in Fig. 5, the stem portion 40 of the adjustable art 19 is received within a longitudinal slot 41 in the fixed part 18. The particular advantage of this form of liner is that the adjustable part 19 is always maintained in alinement with the fixed member 18 and can be freely moved longitudinally to adjust .the length of the mold slot. I sometimes prefer to make the

recesses

32 and 34 with parallel instead of fiarin side walls so that the two parts of the liner can be freely separated and I have illustrated this form in Figs. 5 and 6. I sometimes prefer to hold the two parts of the adjustable liner together by means of frictional engagement and the forms of the invention illustrated in Figs.

5 and 7 illustrate different methods by which this frictional engagement may be produced. In these forms the fixed member 18 is provided with a longitudinal slot 41 to receive the stem +10 of the adjustable member 19 and the portions forming the lateral walls of this slot may be sprung together slightly before the stem is entered between them so that when the stem is in place it will be retained by a slight spring pressure. In the form of the invention illustrated in Fig. 5 I make the contacting surfaces 40 between the stem 40 of the member 19 and the walls of the slot 41 slightly inclined vertically toward each other so that the stem can be freely entered into the slot from the lower side springing the walls of the slot apart as it is forced into its proper position. The form of the invention illustrated in Figs. 7, 8 and 9 has the peculiar advantage that the movable member 9 is in a sense telescopically mounted upon the member 18 and the two parts are therefore less liable to become separated from each other when not in the mold. In this form the stem portion 42 of the movable part 19 is V-shaped on its lateral edges and the body portion 43 of the fixed part 18 is provided with a longitudmal groove 44 having longitudinal V grooves to receive the V-sliaped edges of the stem 42..

In the form illustrated in Figs. 7 8 and 9 the stem 42 of the adjustable part 19 is provided on its under side with transverse grooves 45 for the purpose of allowing the molten type metal to fill in the space 46 at the front edge of the liner as well as the space at the rear edge, to form an additional spacer similar to the soft metal spacer 35. The two spacers are united together by the type metal which fills the grooves 45.

As many modifications of my invention will readily suggest themselves to one skilled in the art, I do not limit my invention to the specific structures herein illustrated and described.
