MOLD CAP.

Application filed October 25, 1921. Serial No. 510,378.

To all whom it"mag concern:

Be it known that I, EDMOND H. NnILL, a citizen of the United States, residing at Austin, in the county of Travis and State of Texas, have invented new and useful Improvements in Mold Caps, of which the following is a specification.

.My invention has reference to a casting 'mold for matrix setting and line casting machines, by means of which the casting slot can be accurately'set to given fractions or typographical measuring units.

In the accompanying drawings Figure 1 is a front elevation of the casting mold;

Figure 2 is a plan view looking toward the inner face of the mold cap.

Figure 8 is a plan view of the mold body.

Figure 4 is a side elevation of one of the end filler blocks.

Figure 5 is an end view thereof.

Figure 6 is a view 1 illustrating more clearly the taper at. the top edge of the filler block as well as the opening through which the. securing screw passes.

Figure 7 1s afragmentary elevation of the mold cap, illustrating the arrangement 01":

the slots for the quad.

Figure 8 is an end view of the mold cap illustrating the beveled front edge to accommodate the screw driver in engaging lip of quad.

Figure 9 is an elevation of the quad.

Figure 10 is a view of the spacer block.

Figure 11 is a plan View thereof.

Figure 12 is a side elevation thereof.

As is well known in the art the ordinary casting mold is-composed of a cap, a base, and two liners between the cap and base at the ends thereof. llhe cap is pressed down 011 the liner by three screws in the mold wheel, one on each end of the cap and the other at the center. In changing the size or length of a mold, that is'the length of the slug the mold is set to cast, it is necessary to loosen-all three of: the screws, pull out the liners and replace them with others of the required size and length. For instance, say the mold is set for an 8 point slug .18 ems long and it is desired to change it to a 10 point slug 13 ems in length, the liners being both 8 points, one 0 ems and the other 12 ems, and, as the length of the mold on the inside is 30 ems, this leaves the mold slot 18 cms in length and 8 points thick. To change to the above measurements the three mold cap screws are loosened and the 8 point liners are withdrawn, while a 10 point liner is arranged in one end of the mold and a 10 point liner 11 ems long is arranged in the other end of the mold. The cap is then pressed down on the liners by ad usting the screws and the mold slot is 10 points thick and 13 ems'long. This is comparatively an easy operation if there are sufficient liners on hand, but as machines are required to set almost every measure from f to 30 ems on slugs of various sizes from 6 to 36 points.

an extent that it will not eject through the trimming knives.

YVith my improvement, the mold is constructed substantially similar to that of the ordinary mold, the body 1 of the mold, at its upper edge being provided adjacent its end with the usual notch 2, and a cap 3 being provided upon its under face, adjacent its ends with a plurality of transversely arranged slots or notches i, 5 and 6 respec-' tively. Between theinner notchese the inner edge of the cap 3 is formed with transverse depressions which define straight and angular walls and which are indicated by the numeral 7.

Instead of employing liners in the usual manner between the confronting faces of the body cap, at the ends thereof, I make use of filler blocks 8 respectively. These filler blocksare each in the nature of a flat plate and each has its under faces formed with a lug which is designed to be received in the not-ch 2, the outer ends of the filler blocks being in contacting engagement with the posts 10 on the ends of the body 1. The upper face of the filler blockis provided with spaced notches 11 and 12 respectively, while the inner end of each filler block is provided with an upstanding lug 13, the said lugs being disposed over the notch t inthe cap 8. Each filler block has a prefer- ,ably reamed opening therethrough and through this opening there is passed a headed screw 14 which enters a threaded opening in the body 1.

it will be noted that the lugs 15 and 16 provided by the depressions 11 and 12 are disposed opposite the notches 5 and 6 in the SllOUil'ClGFS between the depressions at, 5 and 6 in accordance with the width desired in the casting slot, it being understood that the lug 13 is never entirely withdrawn from the notch 4, and also that the notch 4 is of agreater depth than the notches 5 and 6.

It will thus be noted that the thickness of'the slug may be readily adjusted by the operator,- and also that the operator can make such adjustment without necessitating him leaving his seat, it being merely necessary'to withdraw thequad from one of its mentioned positions and reinserting the same in another position. To facilitate this the outer or preferably upper corner of the quad is formed with a ledge or lip and also the quad is beveled or arranged at an inclination. It add1t1on to this the employment of the end mold cap screws may be dispensed with. The pressure from the central mold cap screw 'eitectively holds the quadsin effective engagement with the tiller blocks.

To regulate the slot so that slugs of desired lengths can be cast I make use of what I will term spacer blocks and which are indicated in the drawings by the numeral 18. These spacer blocks are of a slze to be re'ceivedin the slot in the mold and as illustratedin Figure 10 of the drawings, the

same may be provided with a plurality of teeth 20 to be received in the substantially V-shaped notches 7 in the inner face 01 the cap also, if desired, the spacer block may be provided with a single tooth. The teeth 20 of the spacer block fit snugly in the notches 7 in the mold cap, and'hold the same positively in position, and of course, the space between the filler block and the spacer block on the right hand side of the mold determines the length of the slot and consequently the length of the slug to be cast. To facilitate the insertion and withdrawal of the fillerblocl ts the same are, as illustrated in the drawings substantially beveled or wedge -shap'ed having their inner ends rounded and their outer edges formed with lips for engagement by a suitable instrument suchas a screw driver, or if desired by the fingers oi the operator.

The spacer blocks, it is to be noted'are of a similar construction, and are reversely arranged in position in the mold. No change is made in the mold base and but few changes are necessitated in the mold cap in providing the same with my improvement, while the element which I have re terred to as a quad is really in the nature of a key which is gof an inch long and 10 points square, with the exception of ends, one of which is provided with a lip, and the other rounded or tapered to permit the ready removal and insertion of the same.

It is also believed that the foregoing de scription, when taken in connection with the drawings will fully set forth the construction and advantages of the improve' ment to. those skilled in the art to which said invention relates and that further detailed description will not beneeessary. It

is, or course, to be understood that I am entitledito such changes from the showing and description as may be found necessary or desirable in the manufacture thereof, such changes however, not departing from the scape of theappended claims.
