TYPE MOLD AND MATRIX.

Patented Feb. 26, 1907.;

To all whom it may concern:

Be it known that we, FRANK H. BROWN i and JOHN E. HANRAHAN, of the city of Baltimore and State oi Maryland, and GEORGE A. BOYDEN, of Mount Washington, in the county of Baltimore, State of Maryland, citizens of the United States, have invented certain new and useful Improvements in Type Molds and Matrices, of which the following is a specification.

. This invention relates to type-molds, and has among its objects to provide a mold by which type of a wide range of sizes and styles may be cast and by which the changes from one size type to another may be made quickly and the centering of the type character on the matrix with respect to the mold-cavity be made accurately without measurement and by unskilled labor.

Theinvention is illustratedin the accompanying drawings, in which,

Figure 1 shows a perspective view of the mold parts. Figs.2, 3, and 4 show sectional views of insert-molds and portions of ejectors of various sizes. Fi s. 5, 6, 7, 8, 9, and 10 show matrix-plates a l of a uniform or equal ters they contain. Figs. 11 and 12 show space or quad matrix plates. Figs. 13, 14, 15, 16, 17, and 18 show ty e of varying sizes cast from matrices the p ates of which are of uniform size, all cast i'rom the same stationary mold part. Figs. 19 and 20 show spaces and quads of different sizes. Fig. 21 s owe a longitudinal section through the insert-mold part with the matrix-holder and matrix held in place by the adjusting or centering screw, and Fig. 22 shows aperspective view of the matrix-holder with the centering recess in the rear side thereof.

Heretofore it has been the practice in making tjr e, s aces, and 'quads to have separate mo d mec anism for each bod wise size of type and to use matrices forme in lates varying widely in dimensions to accor with the size of the type to be made. This old ethod requires .a change of all the mold rts and numerous adjustment of same each time a change is made from one size or kind of type to another and also requires numerous adjustments of the matrices with respect to the mold to get the type character on the matrix properly situated or centered,

the whole requiring skilled labor of exceptional ability. The dilliculties inherent in this method have resulted in confining the maninacture of type to i'oundries provided with special equipment and skilled labor, and the type thus produced has been sold from the Ioundries and distributed to printers throughout the country.

The present invention contributes in an important manner to the overcoming of many of the diiiiculties herein mentioned and enables the method or practice alluded to to be dispensed with. j

The mold in this instance consists of four parts-a stationary mold part 1, which in practice is permanently attached to the castmg mechanism and is used to cast all kinds' and sizes of type within the size range of the machine; an insert-mold part 2, an ejector 3, and a matrix.

The plate or body part of the matrices will be of a uniform size irrespective. of the size or kind of t pe character; but the insert-mold parts and the ejectors will vary in size as to their bodywise ca acity, and the difl'erent sizes will be interc angeable with respect to the stationary mold part. The arrangement, construction, and o eration of all these parts is such that their a justment for ty e of different sizes will not require special sizill.

The stationa mold art consists of a baseblock 4, which orms t e bottom wall of the type-cavity and is provided with a nippleplate 5, through a hole in which not shown) the metal is su plied to the mold-cavity in casting. An aiiutment 6 is attached rigidly to the base-block 4, and against this abutment a shoulder on the ejector 3 strikes when it is in the casting position. A series of thin plates 7 of dilierent thicknesses, which we term liners, are employed. Any selected number of these liners maybe placed against the abutment 6 to govern the position oi the cjecior, and thereby regulate the sctwise size of the type-cavity to correspond with the type characters.

On top of the base-block is the ejector 3, which forms one side wall of the type-cavity. This ejector has a reciprocating movement on the base-block 4, by which the type is ejected from the mold parts ai'ter beingcast. In one side of the ejector is a recess 8, which permits the reciprocation of the ejector past the abutment 6. A shoulder at one end of the said rece strikes against the abutment 6 (or against the liners 7 when the latter are inserted) when the ejector is in the casting position, as before stated.

The insert-mold part 2 consists of a rightangle piece which forms two of the walls of the mold-cavitythat is, the top -and one side-when placed in position with respect to the stationary mold and ejector. The insertmold part is provided with a recess 11 and a matrix-holder which receives and properly locates any one of the matrices irrespective of the size or kind of type to be cast, and this matrix-holder consists of a backing-plate 9, provided with )rojecting flanges 10, so arranged that eac matrix of the font or any matrix of any font can be readily placed in said holder between said flanges in proper position for casting purposes without measuring or requiring skill. This matrix-holder containing the desired matrixds then placed in a recess 11 in the insert-mold part especially designed to receive it, and by means of a centering-screw 12, having a cone-shaped end 13, which enters a similarly-shaped recess 14 in the matrix-holder, said holder containing the matrix may be accurately centered by merely turnin the screw, which also holds and keeps the proper position in the insert-mold art.

All matrix-plates to be used wit the mold mechanism are to be of a uniform size irrespective of the size or kind of type characters, spaces quada or, ornament to be cast from t em, and the type character in each and all of the matrix-plates has the same predetermined position with respect to one vertical ed e and the bottom edge of the plate and is so ocated that every matrix of a font or of a series 01 fonts is interchangeable with the mold mechanism. In changing from one setwise size tvpe character to another all that is required to center the character on the matrix with respect to the mold-cavity is to place the matrix in the matrix-holder 9 and secure the holder and matrix in the insertmold part 2 by turning the screw 12. The

- matrix-holder will thereby be shifted to ac curately center the matrix character with respect-to the mold-cavity, and the whole is ready for casting the type selected without having required skilled labor.

It will also be seen that no matter what the size of the character on the matrix-plate may be the turning of the screw Wlll cause the character to take its correct position, and the adjustment is the same in every case.

It will also be seen that as the matrixplates are all of a uniform size and the characters thereon have the same position 'with respect to two edges of the matrix-plate when a matrix is placed in the holder the character irrespective of its size will have the same definite position with respect to the reolder And matrix in cess in the back of the holder, and therefore the centering of the matrix can be readily accomplished by the adjusting-screw entering said recess.

Having thus described ourinvention, what we claim as new, and desire to secure by Let-. ters Patent, is- 1 1. In a machine for casting type, the combination of a type-mold having a movable ejector forming one side of the mold cavity; a matrix-plate having a casting-surface whose area is of size sufficient to receive any type'character from the smallest to the largest dimensions. for which the machine has capacity-said character, irrespective of its size, being situated on the said plate at a pr'edetermined measurement from one vertical edge and the bottom edge of said plate;-and

insertible and removable liners which by limiting the movement of the ejector governs. the setwise size of the mold-cavity.-

2. In a machine for casting type, the combination of a type-mold comprising a-stationary part and an insertible part; a matrix plate carried by the said insertible'part and iaving a casting-surface whose-area is of size sufficient to receive any type character-from the smallest to the largest dimensions for which the'machine has capacity-said'Chttfiacter, irrespective of its size, being situated on the said plate at a predetermined meals" urement from one vertical edge and the bottom edge of said plate; and means also on'th'e insertible part of the mold to shift the-'matrix-plate so as to center the matrix'chara'c ter with respect to the mold-cavity.
