MANUFACTURE OF STEREOTYPE-PLATES.
T 0 all whom it may concern.
Be it known that I, ARTHUR Du'rron, British subject, residing at Buncorn, county of Chester, England, have invented certain new and useful Improvements in the Manufacture of Stereotype-Plates, of which the following is a specification.
This invention relates to improvements in the manufacture of stereotype blocks for printing purposes and is designed to provide improved means for the manufacture of blocks accurate as to type height and size according to the point system of measurement.
The invention will be described with reference to the accompanying drawings.
Figure 1 is a plan view of the gages arranged around a form from which a block is to be formed. Fig. 2 is a side elevation, with parts in section, of Fig. 1, showing the pouring opening. Fig. 3 is a view, similar to Fig. 2, but showing a modified form of pouring opening. Fig. l is a longitudinal sectional view of the mold, showing the cores in position for pouring. Fig. 5 is a transverse sectional view of said mold. Fig. 6 is an inverted plan view of the core plate and cores. Fig. 7 is a fragmental inverted plan view of a modified arrangement of core plate and cores. Fig. 8 is a side elevation, partly in section, of a further modification of core plate and cores. Fig. 9 is a fragmental inverted plan view of a still further modification. Figs. 10 to 13, inclusive, are fragmental plan views of various devices which may be employed for connecting the gages. Fig. 14: is a fragmental plan view of a further modified gage construction.
In carrying out the invention the matter of which it is desired to produce a block is set up in a form in the usual way. This matter may consist of ordinary type, wood cuts, electros, zincos, or any other surface from which an impression can be made. This form is carefully made of exact type height and may be tested for accuracy by taking proofs therefrom. Where ordinary type alone is employed this proofing is of course not necessary. The sizes of the form built up of type or quads in this way bear definite and standard relations to each other according to what is known as the point system, that is to say the length and width of the form are definite multiples of a cer- Specification of Letters Patent.

Serial No. 532,888.
tain type unit known as a point and in cases where this is not so the form can be packed to such standard sizes. Closely around the forms produced in this way of such a standard size, are fitted metal gages A of exact type height the gages being made in sets, the lengths of which are calculated according to the standard multiples of the point unit above mentioned. These gages are preferably formed with dovetail or rabbeted joints a to make a perfect joint with the adjacent gages at the corners.
The faces of the gages being'type high are in the same plane-as the face of the type and at distances along the faces of the gages small holes B are formed. The gages are then tied or otherwise secured around the form in any suitable way, and a matrix C is formed in a press in any suitable way. This matrix in addition to the impression of the form also bears impressions of the holes or recesses B in the faces of the gages.
When the matrix C is ready it is removed from the form and the gages A surrounding the form are also removed. The gages A are then placed on or around the matrix C in such a manner that the holes B on the faces of the gages register with the impressions previously formed by them on the matrix, thus inclosing the matrix in a space exactly the same size as the form and exactly type high. On top of the gages is clamped or otherwise secured a plate D to tighten the parts in position and the metal is then poured into the space between the matrix C and the gages A and the plate D through any suitable opening in one of the gages. This opening may be constituted by an elongated slot H, formed laterally through the gage, as shown by Fig. 2, or by a series of lateral perforations H, as shown in Fig. 3. Small passages or air outlets E are preferably formed at the back of the gages A or through the clamping plates D for the escape of theair from the mold. In this way a block of absolute type height and of accurate standard size can be pre pared, all that is necessary to complete the 'block being to trim any unevenness where the metal has been poured or where it has flowed into the air outlet.
When a divided gage of the type shown in Fig. 3 is used for the inlet of the metal, after the cast has cooled all that is necessary is to knock oif the small tongues of metal. which are left and a block of accuate size to the point system requiring practically no trimming is the result.
A modified form of gage A for producing blocks of fixed width but variable length may be constructed of l. shape as shown in Fig. 14:. Vi hen a block is to be formed of this character two of such gages A of the same width are placed together and can be slid upon one another until a space of the desired length is produced. To lighten the blocks rib like cores F may be formed on the clamping plate D for forming the mold, and these cores are preferably screwed or otherwise made adjustable to the plate so that they can be adjusted or removed to permit of the plate I) being used for different sizes of blocks. Or the clamping plate 13, ee Figs. 7 and 8, may be made in sections (1, each section being provided with a core piece F formed integral therewith or screwed or otherwise attached thereto. These sections (Z may be arranged to butt against each other or may be made with rabbeted or tongue and groove or other joints. Or the cores may be divided as shown in Fig. 9 into smaller sections 7 which may be formed with or secured to the plate D or plate sect-ions (Z-as above described. If an unshrinkable matrix is used which is also unaffected by heat such as is described in the specification of my concurrent application Serial No. 532869 filed December 13, 1909, blocks of harder metal than previously used, which require greater heat to melt them can be produced. From one such matrix by this process a number of absolutely identical blocks can he prepared. A number of identical perfect half tone blocks can also be prepared of absolutely accurate register so that they can be used for the three color printing process.
hat I claim as my invention and desire to protect by Letters Patent is 1. A gage for stereotype-block casting apparatus provided upon its under face with means for producing centering impressions upon the matrix.
2. A gage for stereotype-block casting apparatus provided upon its under face with recesses for producing centering projections upon the matrix.
3. A gage for stereotype-block casting apparatus having its back provided with air vents and its under face provided with means for producing centering impressions upon the matrix.
4. A gage for stereotype-block casting apparatus constructed of standard lengths according to the point system and having its under face provided with recesses for pro ducing centering projections upon the matrix.
5. A gage for stereotype-block casting apparatus constructed of standard lengths ac cording to the point system and provided with a pouring opening, said gage having its under face provided with means for pro ducing centering impressions upon the matrix.
6. The combination of a series of re1n0vably connected gages constructed of standard lengths according to the point system and adapted to surround the matrix, and a core plate mounted upon the gages and provided with depending cores, one of said gages having a pouring opening formed therein.
In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
