Tog/ll. whom. it may cbncern:
. e it known that we, FRANK H. BROWN and JOHN E. HANRAHAN, of Baltimore city, @IldGEORGE A. BoYDE'N, of Mount Washing- 5 ton, 1n the county of Baltimore and State of "Maryland, have invented certain new and useful Improvements in Master-Blocks for Ma Matrices; and we do hereby declare ythe fol owing to be a full, clear, and exact dei -o sor'iption of the invention, such as'will enable others skilled in the art to which it appertains to make and use the same. l This invention relates to master making and has for its object the formation of a mas-.
:"ter block i wherein the ,type character and master made integral with each other, by wh1ch'a large number of masterblocks having the same character are economically and accurately produced, whereby the produc- 2p tion of matrices in large quantitieshaving the same character is greatly facilitated.
H With the. introduction 'of the sorts ma- A -chine for casting typeflinvented by these same inventors,ithe art 'of producing type at this time is being revolutionized, for the reasonthat instead-"ofmaking type under the present foundry practice with skilled labor and then distributing the type throughout the country for printers to use, the printers are producin type in their own ofiices 'with unskilled, la or. This results in a great saving of time and money and affords convenience in producing immediately type andsorts when needed. This innovation necessitated 3 5 the creation of various systems and inven tions, not only with relation to the type casting machine proper, but also-in molds, mold making, matricesand mtatrix making, and to one of these systems 'thispresent invention 4o relates.
In the accompanying drawing :-Figure 1 represents the front view of a master block with the character thereon, Fig. 2-is asection of Fig. 1 on-line X, showing the type character lntegral with theblock. Fig. 3 is i a holding flask inwhich are placed a number of master blocks, having the same type 'character, after the. matrix plates are secured to them, and by which any one character is du- 5o .p'licated in large quantities in the same time required for one.
Specification of Letters Patent. A lication filed May 18,1905. Serial No. 261,038.
Patented May 21, 1907.
Referring to the drawing, it will be observed that the matrix block A has the character I) definitely located thereon, in predetermined position With relation to one vertical and one horizontal edge of the block, said character being cast integral with said block, by which the character'is produced at the same time the block A is made. In the operation of producing the duplicate master blocks the original master block is first employed to make a master matrix. This master matrix is thenplaced in a suitable mold, properly constructed to cast the duplicate master block of proper dimensions. From this matrix and mold any number of master blocks Acan be cast, having the character I) integral with the block, whereby, after the expensive original master block is made, any number of duplicates thereof can be quickly, accurately and cheaply produced, by virtue of which, to make 100 matrices of the character T to supply machines in as many printing ofices, it is only necessary to cast 100 master blocks A, as set. forth, place them in the holding flask c as shown in Fig.- 3, with the-matrix plates B arranged with the master blocks in proper order, and the. same waxed and submitted to metal deposition, whereby the amount of time consumed in the deposition of 100 matrix plates is no greater than would be required for the deposition of one. This, of course, greatly reduces the time and cost of production, and makes it possible to supply matrices at a non-prohibitive price to the printer, assuring economies to him that induce a preference to the pur-- chase of type, because of great savings.
t will be understood that the face of the master block herein described is of the same dimensions of the matrix may conform to any'standard of measurement now employed by type founders or which may hereafter be. adopted, without departingfrom the spirit- -of our-invention.
