sTEREOTYPlNc-MAOHINE.

SPECIFICATION forming part of Letters Patent No. 537,183, dated April 9, 189 5.

Application filed September 29, 1894. Serial No. 524,455. (No model.)

To all whom it may concern..-

Be it known that I, WILLIAM BUOHER, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Stereotyping-Machines, of which the following isa specification.

My invention relates to stereotyping machines and the objects ofmy invention are to provide a combined stereotyping furnace and casting box of superior construction and arrangement of parts which will greatly facilitate the production of stereotype plates and to provide other improvements in details of construction which willbe more fully pointed out hereinafter. These objects I accomplish in the manner illustrated in the accompanying drawings, in which- Figure l is a view in perspective of my improved stereotyping furnace or stove and casting` box, showing the latter open and supported in a horizontal position from the stove. Fig. 2 is a perspective view of the same showing the position of the parts when the metal is being poured into the casting box and Fig. 3 is a central vertical section of the same.

Similar letters refertosimilar parts throughout. the several views. v l Y a represents the furnace or stove body which lhas a general rectangular stove form. Supported within the stove casing in the forward portion thereof is a desirable form of tire box b, with which 'a doorway b', formed inthe front of the stove case, communicates in the usual manner. In the upper and rear portions of the stove is provided the usual smoke outlet b2 and in the stove back plate which-is indicated at b3 are formed upper and lower transverse flue openings b4. A

b5 represents a transverse damper plate which is supported upon a horizontal damper rod b6 which extends through the rear portion ot' the stove body, said damper plate being adapted, as shown, to be inclined in such position as to prevent a direct draft of the smoke from the fire box through the upper heat dame opening b4 or to regulate the draft from the re box to the smoke outlet b2.

c represents 'two oppositely located and parallel projecting arms which extend rearwardly from the upper portion ofthe stove. Between the inner end portions or shanks of these arms vc extends transversely in a position adjacent to the stove top a fixed hinge rod c on which is fulcrumed or which is loosely surrounded by a tubular tongue extension c2 formed on one end of the casting box base plate c3. This base plate-is provided, as shown in the drawings, with two laterally projecting and upwardly extending oppositely located standards d. On the outer side of each of the rearwardly projecting arms c of the stove is pivoted as indicated at d an angular catch d2 one arm of which, which I term the Yrear arm being adapted to drop below a horizontal position by reason of its engagement with a shoulder d3 formed in the side of the frame arm c. As shown in the drawings these rear arms of the catch piece are adapted to support the casting box base plate in the horizonvtal position shown in Fig. l of the drawings, by forming a rest for the projecting portions Of the standards d.

The under side of the base plate c8 is provided with a depression c6 which, as shown in Fig. 3 of the drawings, extends throughout the greater portion of the length of said plate.

The outer end ot the .base plate c3 is provided adjacent to each side thereof with a link shaped projection e and journaled in these links are the ends of a transverse hinge or rod c the latter being supported by lugs e2 which project from one end of the casting box cover plate f. As shown in the drawings, the outer termination of each of the standards d of the base plate is in the form of a pin or bolt d4' and upon one of these pinr terminations is loosely mounted and supported, one end of a set screw bar f the opposite end of which is in the form of a vertical hook f2 said hook being adapted when said bar is swung cros'swise over the bed plate to engage with the opposite standard pin d4. Through a cen- IOO- ` ofthe drawings.

metal reservoir or kettle g. The upper edge of this kettle which is of a general oblong form, is provided with a projecting flange g which is adapted to rest upon the stove top about the mouth of the opening d2 and the rear side of said kettle is inclined, as shown, to meet the upper side thereof, thus forming the substantially scoop shaped body shown. As indicated in the drawings the rear end of the kettle is provided with projecting hinge rings g2 which enter openings in the tubular hinge tongue c2 and through which pass the fixed hinge rod c.

In the production ot the casting box top platefI form the inner or upper end thereof with an outward bevel as indicated at f6 while a similar bevel c5 is formed on the hinged end of the bed plate, thus providing when said top plate and bed plate are closed toward each other, a mouth space between said bevels.

The operation of my device is substantially as follows: The type form from which the stereotype plates are to be produced, is placed upon the bed plate, the latter being supported by the means described in `the horizontal position shown in Fig. l of the drawings. rlhe form thus arranged is covered in the usual manner by the damp papier-mache sheet. After subjecting the paper to the usual pounding process and applying the blankets, the lid or cover f is let down, the bar f turned across said lid and engaged with the opposite standard termination d4 and the screw f3 screwed firmly into the socketf5 of the lid or cover. This being accomplished, the casting box is disengaged from t'ne catches d2 by slightly elevating the former and forcing the latter out of the way when said casting box may be swung downward to the vertical positions shown in Figs. 2 and 3 ofthe drawings. The base plate being made to bear, as shown, against the stove back and its depressed portion c being thus broughtinto communication with the interiorof the stove through the openings b4, the casting box will thus be subjected to the direct heat which passes through the openings b4 and through said depression. In this position it is evident that the papier-mach matrix will be rapidly and uniformly dried, after which the casting box may be returned to its former horizontal position, the top form removed, the edges of the dried matrix trimmed and said matrix placed in the casting box where its edges may be bound by the usual frame pieces h which for the sake of clearness, are shown upon the base plate in Fig. l The box being again turned downward to the position shown in the drawings, the melted metal which is contained in the kettle g may be readily poured into the mouth formed as described in the upper end of the casting box, the melted metal being discharged directly from the kettle by tilting stereotype plates.

the latter to the position shown in Fig. 2 of the drawings. The metal which is thus poured or brought into contact with the type depressions of the matrix, soon sets and after which the box may be bound and both the plate and matrix removed in the usual manner.

From the construction and operation which I have herein shown and described, it will be evident that a com paratively simple and rapid method is provided for the manufacture of Owing to the peculiar connection of the stove or furnace with the metal kettle and casting box, it will be seen that the drying of the matrix maybe completed in an exceedingly short space of time and that the necessity of ladling the melted metal is entirely obviated. It is also evident that by drying the matrix in the manner described, the heat to which the same is subjected will be distributed uniformly and that the type can in no wise be injured.

It is evident that my improved stereotyping device may be produced at a reasonable cost of manufacture in a neat and desirable form.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. Inastereotyping device the combination with a stove body of a casting box bed plate hinged to said body and adapted to be dropped against the rear side of said stove, a cover plate hinged to said bed plate and means for supportingsaid casting box from the stove in a horizontal position, substantially as and for the purpose specified.

2. In a stereotyping device the combination with a stove body and one or more openings in the back thereof, of the casting box bed plate having a depressed face as described, said bed plate being hinged to said body and adapted to be dropped against the stove back and over said opening, a cover plate hinged to said bed plate and catches for supporting said casting box in a horizontal position from the stove, substantially as and for the purpose specified.

' 3. In a stereotyping machine the combination with a stove body, of a casting box bed plate hinged to said body and adapted to be dropped against the rear side of said stove, a cover plate hinged to said bed plate, of a melting kettle supported as described in the upper portion of said stove, said kettle being hinged at one end and adapted to be supported in a position for pouring its contents into the casting box, substantially as and for the purpose specified.
