The Recessed
In order to cast light-weight slugs and for quick cooling, the recessed mold is made. This mold will cast slugs with cavities, or recesses. The base of this mold is the same as the universal adjustable. The lower surface of the cap has rectangular projections and grooves. The molten metal is forced into these grooves and forms the supporting ribs beneath the type face. The rectangles form the recesses. The weight of the slug is reduced about one-third. A more solid slug is formed because there is less air to be displaced from the mold. There is less metal in the mold cell, therefore it cools more rapidly than the regular universal adjustable. These molds require special left-hand liners and are adjustable for body size from 10- to 14-point and all measures from 8 to 30 picas, except the half-em measures. For these restricted measures a special mold is required and will only be made on special order. In ordering liners for a recessed mold you must be careful to specify “recessed mold” and the length in ems required. These molds can be applied to any model of machine, but must never be used for any size below 10-point.
Display and Headletter
The special display and headletter mold is similar to a recessed mold, but to accommodate the increased size of faces, the recesses are deeper. This mold has practically the same restrictions as to length of slug as the recessed mold. One-letter matrices with the character for raised position must be used on this mold. The filling piece under the first elevator jaws must be used when using the mold. Matrices can not be sent in on the duplex rails of the assembling elevator.
Each display mold has a body range of 5 points only, so the entire range of bodies from 15 to 36 points would require four of these molds as follows: The range of one is 15 to 19 points, that is, any width of liner from 15 to 19 points can be used on this mold; the range of the second would be 20 to 24 points, the third would be 26 to 30 points, the fourth, 32 to 36 points. The range of the molds are always marked on the cap so no mistake can be made.
In ordering liners for the display and headletter molds, care must be taken to specify the range marked on the cap.
These molds are limited as to length of measure the same as the recessed molds.
Advertising
The advertising figure mold differs from the universal adjustable only in the mold cap. The cap is constructed with an extra thick lip against which the overhang in the matrices are cast. This permits of casting large characters, which will lap over one or more adjacent slugs. The grooves in the cap are ground parallel. With this mold slugs from 5- to 12-point can be cast, but not above 12-point at any time. This mold can also be used for casting headletter type, by letting the letter overhang the slug. Place a blank slug underneath the overhanging letters to support them.
When using the advertising figure equipment, display figures or characters can be cast at any desired point in the line of text matter, the characters or figures casting on the first slug against the lip of the mold, thus overhanging one or more other slugs when assembled.
