MOLD.
Application filed August 27, 1925.
This invention relates generally to molds. More particularly, my present invention relates to a certain new and useful improvement in molds employed in the casting or production of brass or bronze billets and has for its primary object the provision of a mold for enabling the economical, convenient, and facile production of especially billets of'the' kind mentioned,
And withtli'e' above and other objects in view, myinvent ioii resides'in the novel features of form, construction, arrangement, and combination ottparts[hereinafter described and'pointed o ut'in the claim.
In the-accompanying drawings,
Figure 1 is a vertical sectional view and Figure 2 is a plan-view of a mold embodying my invention.
Referring now more in detail and by reference characters to the drawing, which illustrates a preferred embodiment of my invention, A designates the body or matrix oi the mold, which is of suitable dimensions and material and which includes a base 1, integral with or otherwise conjoined to which is an upstanding preferably cylindrical portion 2 having a suitably elongated cylindrical cavity or casting chamber 3 open at its one or upper end for billet-production. Projecting outwardly from the mold body-portion or matrix 2, are oppositely disposed lugs, trunnions, or the like 4 for faciliting the transport and manipulation of the mold proper A.
Adapted for removable disposition, as well as for axial turning or rotatory movement, upon the upper end of matrix 2 at the mouth of its chamber 3, is a member or socalled cap B, which is'likewise of suitable material and of suitable dimensions relatively to the mold proper A. Formed in the cap B and opening to its opposite ends, is a pouring or gate channel 5, which, as shown, tapers in diametrical dimensions from the one or upper end of cap B to the other or under end thereof, where, as at 6, it discharges into the matrix-chamber 3. Also formed in the cap- B and similarly opening to its opposite ends, is a riser-channel 7,
which is somewhat reduced in diametrical.
dimensions relatively to the gate-channel 5, but which likewise, as shown, tapers in diametrical dimensions from the upper end ofcap B to the under end thereof, where,
Serial No. 52,798.
as at 8, it is adapted for communication with the matrix-chamber 3. Projecting outwardly from cap B, is a pair of oppositely disposed lugs or the like 9 for both facilitating transport of the cap B and effecting rotatory or twisting movement of the cap B upon the mold-body or matrix A.
In use and operation, cap B is mounted or arranged upon the mold-body A at the open end of the casting-chamber 3, as best seen in Figure l. The molten metal is then poured into the chamber 3 through the gate-channel 5, the riser-channel 7 permitting the escape from the mold of air, gases, and other vapors, and the molten metal being so poured into the matrix A until the metal substantially fills not only chamber 3, but also the channels 5 and 7. Upon then hardening or solidification ol the metal, twisting movement is suitably imparted to the cap B, with the el'lect that the gate and riser are sheared at the reduced ends 6 and 8 of the respective channels 5 and 7 from the billet so cast in the chamber 3. The cap B is thereupon bodily lifted and removed from the matrix A, when the billet proper, with both its upper and lower ends substantially smooth and uniform, may be conveniently removed upon suitable manipulation of mold A from the chamber 3, and when also, upon suitable manipulation of cap B, the gate and riser drop from the tapered channels 5 and 7- and are again usable on resmelting.
By my new mold, I am thus enabled economically and conveniently, without waste and obviating the present-day time-consuming and laborious billet-end finishing operations, to produce a billet finished and relatively smooth at its ends,
I am aware that minor changes in the form, construction, arrangement, and combination of the several parts of my new mold may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.
Having thus described my invention, what I claim and desire to secure by Letters Patent is: V V
In a billet-mold, an upstandingmatrix having a longitudinally disposed casting chamber, said chamber being open at the upper end of the matrix, in combination with a cap-casting rested upon the matrix and overthe open end of said chamber, the cap being formed longitudinally with separate tapering pouring and riser channels opening to the upper and lower faces of the cap and each adapted for communication at their reduced loWer end with said chamber,
the cap being smooth upon its under face and adapted for twisting movement upon the matrix for shearing the gate and riser 10 from the billet cast in said chamber.
In testimony whereof, I have signed my name to this specification.
TANNIE I JEWVIN.
