MOLD FOR CASTING PRINTERS FURNITURE.
STEECIFIGATION forming part of Letters Patent No. 733,531, dated July 14, 1903.
Application filed July 5, 1898. Serial No. 685,083. (No modelil T 0 all whmn it may concern.
Be it known that I, lsAAc BAAS, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Molds for Casting Printers Furniture, of which the following is a specification, reference being bad to the accompanying drawings, forming a part thereof.
The main objects of my invention are in the manufacture of printers metal furniture to avoid hand or machine work, planing, or finishing for the purpose of removing the bur left by breaking off the jets and of forming feet for the furniture to stand upon, to form drain-holes through the bodies of the furnicore by simply breaking the jets therefrom, to better distribute the metal'for resisting strain, and to reduce the cost of manufacture.
It consists in certain novel features in the construction of molds for casting metal furniture, as hereinafter particularly described, and pointed out in the claim.
In the accompanying drawings like letters designate the same parts in the several figures.
Figures 1 to 7, inclusive, illustrate a mold embodying myinvention, Fig. 1 being a front elevation of the mold with all the parts except the front plate assembled in position for casting a piece of furniture, Figs. 2, 3, 4, and 5 being perspective views of the upper moldsection, the nipple-plate, the lower mold-section, and the front plate, respectively, Fig. 6 being a vertical cross-section'on the line 6 6, and Fig. 7 a horizontal longitudinal section on the line 7 7, Fig. 1; and Figs. 8 to 11, inclusive, show a piece of metal furniture such as said mold is designed to cast, Fig. 8 being a vertical runningwise section and Fig. 9a bodywise elevation including the jet, Fig.
10 a runningwise section without the jet, and
Fig. 11 a plan view with the jet.
Referring to Figs. 1 to 7, inclusive, A designates the upper part or section, and B the lower part or section, of the mold. These two parts are or may be like or similar to those of molds in common use for casting metal furniture and type. They are brought together in the usual Way, as shown in Figs.
1, 6, and 7, and form a cavity of the exact runningwise and bodywise dimensions of the furniture to be cast. The upper mold-section is shown by itself in Fig. 2 and the lower mold-section in Fig. 4. The cavity thus formed by the upper and lower mold-sections is closed when the parts of the mold are assembled, as seen in Figs. 6 and 7, by the nipple-plate O on the back side next to the melting-pot and by the plate D on the front side of the mold. The nipple-plate O, with the bar E, by which it is supported on a typecasting machine, is shown by itself in perspective' in Fig. 3, the plate D being shown in like manner in Fig. 5. The nipple-plate O is formed or provided on its front face, as shown in Fig. 3, with a pyramidal or tapering boss or projection F, which when the parts of the mold are assembled extends about midway into the cavity formed by the upper and lower mold-sections A and B. A
gate hole or passage f for filling the moldwith type-metal from the melting-pot of the casting-machine is formed through the bar E, nipple-plate O, and boss F, opening at its front or outer end into the mold at or in the apex of said boss. By this means the jet 9 of metal furniture Gis made to join the body in the cavity g, which is formed by the boss F, as shown in Figs, 6, 7, and 8.
For casting furniture like or similar to that shown. in Figs. 8 to 11, inclusive, the plate D is formedor provided with a pyramidal or tapering boss or projection H, as shown in Fig. 5, like or similar to the boss F on the nipple-plate, and this boss H projects about midway into the mold-cavity when the parts of the mold are brought together, as shown in Figs. 6 and 7, so as to form a cavity g in the end of the furniture opposite that formed by the boss F, as shown in Figs. 8 and 10. A space is left between the inner ends of the bosses F and H when the parts of the mold are assembled, so as to form at the base of the jet g a thin partition, by which it is joined to the body of the furniture, as seen in Figs. 6, 7, and 8, and which is broken or driven out with the jet g, thus forming a drain-opening between the cavities g and g Heretofore in casting metal furniture the jet has generally, if not always, been joined to the bottom of the body and has extended completely across it in a runningwise direction. When such a jet is broken 01%, it leaves a bur or rough projection on the bottom of the body, and this has to be planed out, so as to produce feet for the body to stand squarely upon and a drain hole or opening into the cavity formed by a boss on the front plate. In order to produce this drain hole or opening without planing an unnecessarily deep groove in the bottom of the body, the boss for forming the cavity is made relatively much longer than the boss H which I employ in my mold, so as to leave a comparatively thin Wall of metal between the bottom of the cavity and the lower end of the furniture-body.
In metal furniture it is necessary or desirable for greater strength to have the greater thickness or volume of metal about mid way between the ends of the body so as to afiord the greater support at that point. This is accomplished in my improved mold by making the tapering bosses on the front and nipple or back plates extend into the cavity of the mold to points nearly midway between its ends.
From the foregoing it will be apparent that with my improved mold and method of casting, the metal is distributed to better advantage,and the time, labor,and expense required to remove the rough bur left by the jets and to form feet on furniture cast in the ordinary molds in the usual way, are saved, since by simply breaking OK or driving out the jets drain holes or openings are incidentally formed through the bodies.
I claim- A mold for casting metal furniture consisting of the combination with side mold-sections of a back plate having a tapering boss with a gate-hole passing through it for forming a cavity in the end of the furniture-body to which the jet is attached, and afront plate having a similar tapering boss for forming a cavity in the other end of the furniture-body, said bosses project-ing toward each other into the cavity of the mold when the parts are assembled in position for casting, and a thin space being left between the opposing ends of said bosses for the passage of the molten metal from the gate-hole into the mold for forming a fragile partition connecting the jet with the interior walls of the furniture-body between the cavities therein, substantially as described.
In witness whereof I hereto affix my signature in presence of two witnesses.
