TYPE-MATRIX.
SPECIFICATION forming part of Letters Patent No. 569,876, dated October 20, 1896. Application filed February 5, 1896. Serial No. 578,126. (No model.)
To all whom it may concern.-
Be it known that 1, WILLIAM KEMr, Jr., a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Type-Matrices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will e11- able others skilled in the art to which it appertains to make and use the same.
My present invention relates to type-matrices, and has for its object certain improvements which will be fully disclosed in the following specilication and claims.
To overcome the wear incident to the use of type-matrices, it has been the practice to make the matrix of hard metal. such as steel, making the impression in the matrix to form the desired character by the use of dies, but owing to the solidity and hardness of the metal the dies have been rapidly destroyed, which added greatly to the cost, of the matrix. To overcome this cost in making the matrix, a block or base of steel with a cavity in one end filled witha plug of soft metal to receive the impression of the die and form the character has been used, but the durability of this class of matrices was very short, for the reason that the molten metal caused the four side walls of the matrix to close in and thus render the matrix worthless. To overcome this defect in the matrix, a block or base of steel with a section of soft metal in which the character is formed and in which section are two open sides and two walls were used, the remaining two walls of the mat rix being formed by the walls of the slotin the block. This reduced the wear materially, but the cost of manufacturing the matrix was still quite an item of expense.
It is the purpose of this invention to produce a matrix with a cavity having inclosing walls of hard metal yielding the maximum of Wear at a minimum cost of IIRl-IlllfttGlillIB, the character being formed in a superposed body of soft metahwhich constitutes the working bottom only of the, matrix.
For the purpose of illustrating the invention, the accompanyingdrawings, which form part of this specification, show aform of matrix used in casting letters.
In the drawings, Figure 1 represents a vertical section of a block orbase of a matrix in its first stage of construction with a cylindrical opening in it; Fig. 2, an inverted plan view of the same; Fig. 3, a vertical section of the block and a drift or punch for forming a recess or cavity in the upper end of the block; Fig. 4, a vertical sect-ion of the block with the cavity formed in its upper end and the cylindrical opening below it; Fig. 5, a top plan of the same; Fig. 6, a vertical section of the block and a punch for forming a character witha strip of soft metal between them; Fig. 7, a like view showing the punch in the recess or cavity in the block or matrix and the superposed bottom seated; Fig. 8, a like view of the completed matrix; Fig. 9, a top plan View of the same; Fig. 10, a perspective of the drift or punch for forming the recess or cavity in the block; Fig. 1.1, a like View of the punch for forming the superposed bottom of the matrix and the character in the cavity in the block, and Fig. 12 a perspective of a strip of soft metal for supplying the superposed bottom of the matrix.
Reference being had to the drawings and the letters thereon, A indicates the block or base of the matrix, in which an elongated oylindrical opening ais drilled from the lower end of the block to near the upper end, leaving sufficient metal in the upper end to form the primary bottom of the matrix and the recess or cavity 1), which subsequently becomes the matrix and is formed by a drift or punch B, having a die 0 on one end, which is driven into the upper end or face of the cold block A and forces the metal above the bore a downward into the upper end thereof and forms a primary bottom d of the matrix. The cavity 1) being of substantially the same crosssectional area as the opening a, the metal above the opening a yields readily tothe drift 15 and its die a, and thereby greatly facilitates the work of forming the matrix, and relieves the die of the major portion of the wear and tear to which dies for this purpose are subjected in the prevailing practice of making matrices.
The recess or cavity b having been formed in the block A, a superposed bottom e is supplied to the recess by placing over or upon the upper end of the block a cold strip 0 of soft metal, such as'copper brass, or other suitable metal, and by the use of a punch I), having a diefthe size of the cavity 1), which die has a character g formed thereon. A piece of the soft-metal strip 0 of the crosssectional area of the cavity 1) is cut out of the strip, forced down into the cavity upon the primary bottom d, and forms the character it in the upper face of the soft metal, which then becomes the superposed and working bottom cof the matrix E, and the character has been formed by the least possible wear upon the diefof the punch D. The matrixcavity thus formed is provided with inclosing Walls of hard metal capable of resisting the Wear of the molten metal in casting type and is produced at a minimum cost.
The drift B and the punch D do not differ from those in common use in this art.
Having thus fully described my invention, what I claim is 1. A matrix-block having a matrix-cavity with a primary bottom, inclosing Walls all of hard metal and a superposed bottom of soft metal having a character therein.
2. A matrix-block having an opening in the body thereof, a matrix-cavity in the upper end of the block over said opening, inclosing walls all of hard metal, a primary bottom and a superposed bottom of soft metal having a character therein.
A matrix-block having a vertical opening, a matrix-cavity above the opening, inclosing Walls and a primary bottom all of hard metal and said bottom extending into the upper end of said opening; and a superposed bottom of soft metal having a character therein.
4. A matrix-block having; a matrix-cavity provided with inclosing walls all of hard metal and a support, and a bottom of soft metal resting on the support and having a character therein.
In testimony whereof I affix my signature in presence of two Witnesses.
WILLIAM KEMP, JR.
