UNITED STATES PATENT OFFICE.
EDVARD A. HENKLE AND JOSEPH O. FOWLER, OF \VASHINGTON, DISTRIU. OF COLUMBIA.
APPARATUS FOR THE MANUFACTURE OF CURVED LlNOTYPlZ-BARS.
SPECIFICATION forming part of Letters Patent No. 4, 16,738, dated February 1'7, 1891.
Application filed April 15, 1890. Serial No. 348,018. (No model.)
To all whom it may concern.-
Be it known that we, EDWARD A. IIENKLE and JOSEPH C. FOWLER, citizens of the United States, residing at Washington, in the Dis- 5 trict of Columbia, have invented new and usefullmprovelnents in an Apparatus for the Manufacture of Curved Linotype- Bars, of which the following is a specification.
Our invention relates to the construction to of a curved type-bar or line of type cast in a single piece and having the type-faces upon the convex face or edge of said bar and road in g longitudinally thereof.
It is the purpose of our invention to provide a novel and simple apparatus for casting type-bars of this character, for which we have this day filed a separate application for patent.
Our invention consists to this end in the novel apparatus fully set forth in the following specification, and definitely pointed out in the claims annexed thereto.
To enable others skilled in the art to make and use our said invention, we will proceed to describe the same in detail, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of one of the matrices used in the formation of a portion of the type-bar. Fig. 2 is a sectional view of a series of matrices arranged in position to form one wall of a casting-chamber within which the type-bar is formed.
In the said drawings, the reference-numeral 1 denotes a matrix-block possessing in certain respects the characteristic features whereby the block is selected, ejected, and arranged in series with other blocks upon the general plan pursued in the formation of the straight linotype-bars already in use. In our inven- 0 tion, however, we form these bars with sides 2, which are diverged or beveled at an angle coinciding with the angle of radiation of the cylinder upon which the type-bars when cast are to be mounted. For example, in Fig. 2
5 we have illustrated a series of these blocks constructed in the manner specified and locked up within a casting-chamber, the type impressions being formed upon the narrower edges 3 of said blocks, as shown in Fig. 1.
The bcvelin g or diverging faces of the blocks being all of the same angularity, the series of blocks or matrices form when assembled in a series a curve 4., as shown in Fig. 2, the type impressions being formed, as already stated, upon the narrower edges of the blocks, 5 5 which when arranged in proper order form the concave wall of the casting-chamber 5, the end walls thereof being formed upon the radial lines struck from a common center 6. The shorter wall of said chamber is formed by a diaphragm 7, concentric with the matrices 3 and through which the molten typemetal is projected by way of apertures 8 in the usual manner. \Ve thus are able to produce a type-block or line of type cast in a single piece corresponding in form with the shape of the casting-chamber 5, the typefaces being upon the convex face of said typeblock and reading in the direction of its length.
Referring now to our concurrent applica- 7o tion,in which we have shown one means for connecting said type-blocks to'a chase or typecylinder, said means consisting of one or more dovetailed notches formed in the concave edge of the type block or bar, we provide the diaphragm 7 with one or more removable pattern-blocks having a dovetailed rib 10, by which they are detachably connected with a channel in the said diaphragm, the pattern consisting of a dovetailed tenon 12, lying in So the casting-chamber 5 at any suitable point or points, whereby dovetailed transverse channels or notches are formed in the concave edges of the type-bar or line of type to enable them to engage with a correspond- 8 5 ingly-formed rib or tongue on the type-cylinder or on the curved chase carried thereby. This pattern 9, as already stated, is removable in order to facilitate the removal of the type bar or line of type when the latter is cast.
\Vhat we claim is 1. In an apparatus for the manufacture of a curved linotype-bar or line of type, a castin g-chamber having concentric or curved parallel walls for forming the outer face and in- 5 ner or seating edge of the type-bar, the outer or concave wall of said chamber consisting of a series of matrix-blocks having opposite contacting faces which diverge in lines radiating from the center of the concentric I00 walls, the type-matrices being formed upon the narrower edges of said blocks, substantially as described.
2. In an apparatus for the man nfacture of a curved type-bar or line of type, a castingchamber having concentric walls, the outer or concave wall forming the convex face of the type-bar being composed of a series of matrix-blocks 1, having diverging sides 2, and type-1natrices 3, the end walls of said chamber being formed in lines radiating from the center on which the concentric walls are formed, substantially as described.
3. In an apparatus for the manufacture of a curved type-bar or line of type, the combination, with a series of matrix-blocks 1, having contacting faces 2, diverging in lines radiating from a common center and provided with type-1n atrices upon their narrower edges, of a curved convex wall concentric with the face formed by the series of matrix-blocks and provided with openings for the entrance of the melted type-metal, substantially as described.
4. In an apparatus for the manu tacture of a curved type-bar or'line of type, the combination, with a series of matrix-blocks 1, having contacting faces 2, diverging in lines drawn from a common center, the type-matrices being formed upon the narrower edges of said blocks, of a concentric convex wall having openings for the molten type-metal and one or more pattern-blocks having dovetailed ribs lying in transverse grooves in the convex wall and provided with dovetailed tenons projecting above the wall, and two end walls coinciding with lines drawn from the common center, substantially as described.
In testimony whereof we have affixed our signatures in presence of two witnesses.
