Application mea' May 1s, 1911. serial N. 626,959.y
To all 'whom it may concern.' y
Beit known that I, HANS PETERSEN, a citizen of theUnited States, residing at. Minneapolis, in the v'county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Matrices for Linotype-Machines; and I do hereby declare the following to be a full,1 clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My present invention has for its object to provide an improved matrix for use in .linotype machines of the so-call'ed Mergenthaler and analogous types, and to this end the invention consists of the novel construction and arrangement of parts hereinafter described and defined in the claims.
In these linotype machines; as is well known, separate matrices, each representing a letter or character stamped or embossed on the front or working edge of the matrix, are assembled side by side until the desired length of line is attained. Then this line of matrices is presented to one side of the mold containing a slot of the dimensions of the line to be cast, and then the melting pot containing the molten type metal is forced against the other side of the mold slot, and
the metal is pumped or forced into the mold The. result vof this is a cast line or.
slot. slug having the assembled matrix characters in relief upon one edge thereof.
To produce clear or clean cut characters and a solid slug, it is necessary to provide some means forthe escape ofthe air which would otherwise be imprisoned in the mold cavity in the process of casting. Hitherto, this has been imperfectly laccomplished by cutting grooves or small-air vents in the mouth-piece of the metallic casting pot, at
-the rear oflthe mold, thus making it necessary for'the imprisoned air in the mold.,` to force its way around or through the stream of molten metal as it is ejected into the i mold cavity.
My invention, or inrgroved matrix provides an improved or better means for allowing the air to escape from the mold, towit', an arrangement whereby the airis caused or permitted to escape at the front of the mold. This, I have found, may be a .romplished by slightly beveling or chainfering the -front of .the casting edge oft-heg.
matrix, where it comes in contact-with the mold and l extending these beveled edges longitudinally of the matrix face of ,the'mold Another improvedfeature ,in 'the matrix constituting a part ofmy invention, consists in providing the matrix with two sets beyond -the ofdistributing teethin the same edge, with! out increasing the dimensions of the matrix, or in otherwords, without increasing the dimensions which would be' given to the same matrix' even, if provided with but one set of distributing-teeth The improved matrix is acters indicate like parts throughout the several views. 'f
Referring to thev drawings, Figure 1 is a view showing the improved matrix in side elevation and showin the mold in section, som'e parts being bro en away; Fig. 2 is a horizontal section ta-ken on the line :c2 a2 of Fig. l; Fig. 3 is an edge elevation of the improved matrix.
lThe', mold is indicated by the character a -and'the' mold cavity by ythe character al. -The cast slug or linotype` is indicated by .the character y. The body of the improved matrix is indicated by' the numeral 1, and vthe beveled or chamfered edges on the ,front or 'working face thereof, are indicated by the numeral 2. When ,the matrices are assembled together at the mold, as shown in Figs '1 and 2, the beveled edges of the adjacent matrices form very small airl vents that extend from the mold cavity and permit the'escape of air from t-he mold. These channels are so small that the type metal will quickly .solidify therein and, hence, stop ,further discharge of the' metal from the mold. .The tins formed on the opposite faces of the cast slug y may be easily cut off by the trimming knives. Another advantage of beveling the edges of the matrices instead of leaving them perfectly square, as has been the practice heretofore, is that the tendency to raise a bur on this edge is overcome, thus insuring an even and perfect contact between the matrices and the mold, even after they have been in .use for a long time.
In Fig. 1 of the drawings, the letter distributing teeth' are indicated by the numeral illustrated inv the accompanying drawings wherein like char'-,
3. andthe font distributing teeth are indicated by the .numeral 4. The crotch in which the teeth 3y and 4 are exposed is formed With a quite long and straight surface that extends longitudinally of the said matrix, on that sideof the crotch in which the teeth 4. are formed.. This straight sur? teeth and the font distributing teeth of the matrix are -operative While the matrix is in the same or common position, .that is, it is not necessary to invert, or otherwise turn the matrix from one position to another in order to render the saidA letter distributing teeth and fontdistributing teeth operative in succession. What I claim is:
vl. The combination with a mold', of a multiplicity of matrices having beveled j Working edges which, when the matrices are assembled at, the -mold, afford air escape Vents from the mold cavity.
. 2. A matrix having at one end a diverging notch formed on one edgeivith letter distributing teeth and formed on its opposf ingedge With a straight section and with font-distributing teeth, substantialbT as described.
In testimony whereof. I my .signature 1n presence of two Witnesses.
