i'lge Srlgshule ttfetteh in in itin ttittrs mimi mit hitting putt tf tigt stmt.
TO ALL WHOM IT MAY CON CRN Be it known that I, -RIGHARD T. CRANE, .of Chicago, in thecounty of Cook, and State of Illinois, haye invented a new and useful Improvement inV Core-Supports; and I do hereby declare and make known that the following is a full, clear', and exact description ofthe same, referenee'being had to thelaccompanying drawings;
and the letters and gures of'roference marked thereon, 'which form part of this speoieaton.
My said invention relates toa novel core-bar, ory support for the coreof moulds, used for casting vthe return-bends4 or elbows of steam and gas-pipes; and it consists in so constructing said supports that` two of .said bends or4 elbows may be cast together in lone mould; while, at thesame time,rprovisions are made for allowing the escapeof the vapors and gases generated by the molten metal, thus greatly facilitating the casting of said bends anfl 5 elbows, and insuring perfect'eastings, as hereinafter fully described and set forth.
To enable those skilled in the art tomake and use my invention, I will proceed to describe the same with partieularity, making reference in so doing to the. aforesaid drawings, in wl1ich`j` i Figure 1 represents afplan or to'p view of illy-invention. I i
' Figure 2, n. transverse section, at the line a: in iig. `1.
Figure 3, a similar section, at the lin'ey in g. l; and
Figure 4, a plan view of the core, showing the position of the support in dotted lines.
Similar letters of reference inthe several figures denote the same parts of my invention.
lA A represent curved bars, of any suitable metal, connected at their middle-points, or thereabouts, by a cross-bar, B, as shown.v
These bars -are formed in the shape of semi-tubes substantially, so that 'when two are arranged together,
as seenin figs. 2 and 3, and riveted together, as seen in fig. 1, a.' hollow bar is formed, with a. narrow space between the parts, which allows the'gases to enter within and be conveyed to an outlet' in the sand-core C, as shown at drin iig. 4, whence they escape. l i l The bars A may be made stra-iht,I or in any form to adapt them to the purposes to which they are designed. Having described the construction of my invention, I willnow. specify vwhat I claim, and desire to' secure by Letters Patent.
I claim the-combination of the bars A and cross-bar B, when constructed substantially as and for the purposes specified.
