UNITED STATES PATENT WILLIAM W. AYRES, ()F FORT PLAIN, NEW YORK.
MOLD FOR CASTING AXLE-BOXES.
SPECIFICATION forming part of Letters Patent NO. 393,349, dated November 27, 1888.
Application filed August 16, 1888. Serial No. 282,922.
To all whom it may concern.-
Be it known that I, WILLIAM W. AYRES, a citizen of the United States, residing at Fort Plain, in the county of Montgomery and State of New York, have invented a certain new and useful Improvementin Molds for Oastin g Axle- Boxes, of which the following is a full, clear, and exact description.
This invention relates to means for casting the boxes for axles of wagons and other vehicles of that general character.
It is quite important to have axle-boxes as solid and free from air-holes and like imperfections as possible; but as now commonly cast they greatly lack these desirable qualities.
I have found that by casting axle-boxes butt end up and introducing the molten metal from below, the air will be expelled from the mold in advance of the rising metal in the mold instead of being imprisoned in it, and that the castings will be uniformly sound, solid, and free from air-holes.
The invention consists in a mold for casting axle-boxes in which the cavity or matrix is arranged buttend up and gated at the core print or prints in the nowel or below the parting of the cheek and nowel, so that the molten metal only passes into the matrix and the dross and dirt remain in the sprue, while the air is driven out in advance of the rising metal or through ventsin the core, thus producing a clean casting, free from air-holes and quite solid.
I am aware that it is not broadly new in founding to introduce the molten metal from below, and it has been proposed to cast axleboxes by admitting the metal directly into the matrices from a point below the upper ends of the matrices, rather than against the core-print.
In the accompanying drawings, in the two figures of which like parts are similarly des ignated, Figure 1 is a sectional elevation of a three-part flask and mold for practicing my invention; and Fig. 2 is a diagram in perspective of a casting and the cores and runners.
In so far as the more details of the assembling of the flasks and the making of the molds are concerned, the common foundry methods may be pursued in my invention; hence the nowel a, the check I), and the cope 0, together with the dry-sand core (I, the core-prints e e, the vent f, and the flask g g 9, may be as usual.
The invention is economically practiced by (No modohl molding for four, more or less, castings at one time.
h is the matrix or cavity, as shown, to produce the casting butt-end up. These matrices are gated to the sprue t by gates 70, which are arranged below the parting of the cheek and nowel and in the nowel, and the gates are connected to the matrices by elbows 1 next to the core-prints. It will be seen that by this ar rangement of molds, gates, and sprue I admit the molten metal indirectly into the matrices by way of and against the dry-sand coreprint and at the smaller end of the matrices by the elbows of the gates, and the matrices are vented from the larger or but-t end. I thus get rid of the wind or air and impurities, and obtain solid clean castings free from airholes or blow-holes.
In Fig. 2 the cast boxes are designated by Box, and the runners i, It It k k, and Z are formed in the parts respectively designated in Fig. I by the letters 11, it In, and Z.
By using the longitudinal vent throughout the core the steam and gases form a blue flame, escaping upward.
The longitudinal vent may be availed of in making the core to receive a metal rod, which will serve to keep the core straight in drying the same. i
What I claim is- 1. A mold for casting axleboxcs, having a suitable number of cavities arranged butt-end uppermost and gated at the core-prints in the nowel and below the parting of the cheek and nowel, substantially as and for the purpose described.
2. A mold for casting axle-boxes, composed of a nowel and cheek and cope, with the cavities or matrices butt-end up, and cores in said matrices vented longitudinally, a sprue extending from the cope into the nowel, and gates in thenowel leading from the sprue toward the bottoms of the matrices and connected by elbows with the matrices at the core-prints in the nowel and below the parting of the cheek and nowel, all arranged to oper ate substantially as set forth.
In testimony whereof I have hereunto set my hand this 3d day of May, A. D. 1888.
