PIPE-M OLDING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 261,960, dated August 1, 1882.

' Application mediaan-,1123, 1882. (No model.)

To altuwhom it may concern:

Bc it known that I, FREDERICK SHIGKLE, of St. Louis, Missouri, have made a new and useful Improvement in Apparatus for Molding Pipes and other Long Heavy Castings, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, making part of this specification, in Which' Y Figure l is a view in perspective of the improvement, the iiask being opened, and in two of the compartments the sand and pipes being shown; Fig. 2, a plan,'two ofthe compartments being illed; Fig. 3, a horizontal section taken on the line 3 3 of Fig. 4. Fig. 4, a vertical section taken on the line 4 4 of Fig. 2; Fig. 5, a section similar to that of Fig. 3, but showing additional compartments; Fig. 6, another horizontal sectionrillustrating a modification in the relative arrangement of the compartments of the flask; Fig. 7, a ver tical section taken on the line 7 7 ot Fig. 8; and Fig. 8, a horizontal section taken ou the line 8 8 of Fig. 7.

the ask being hinged to the central onelat.

each side thereof, respectively, and forming the copes to the drags ot' the centralpart.

A, Figs. 1, 2, 3, 4, represent an approved form of the flask in question, having the central part, a, and the two side parts, a a', the part a being furnished with suitable brackets-such as t2-for attaching the iiask tothe pit-wall, and the parts a a being hinged Vat ai a3 to the central part, c. As shown in the ligures named, the flask is made to form two pairs, B B and B B', of molding compartments, the central part, a., forming the drags b b b b, and the outer parts, a c', the copes b b bI b', of the various molds.

The pit-wall is not shown, as its construction is well understood, and heilig similar to that shown in patents previously granted nne` for instance, No. 209,139. The iiasks are also, so far as the details thereof are concerned, mainlyr as shown in the patent named.

The -tlaskbottom O can be connected with the tlask-bod yin any desirable manner, the bottom either being entirely removable from the remainder of the construction, hinged to the Hash-body so as to drop downward therefrom, made in sections or in a single piece, or it may be as shown in the drawings-that is, the bottom O is permanently connected with thecentral part, a, and when the parts a a' are opened away from the part a, as shown in Fig. 1 and indicated by the broken lines in Fig. 3, the bottom projects laterally from the central part, as shown in Fig. 1.

The chill or bead ring D is made in sections d d, two or more, and the shell at of the ask does not preferably project or conne directly over the chill-ring, enabling the pipe E, with the inner section of the ring, to be drawn directl y upward in the iiask.

It is evidentvthat a iask constructed upon the present plan can have one, two, three, or more pairs of molding compartments. In Fig. 5a iiask having three pairs, B B B B B2 B2, is shown. In such cases, or even when `oni y two pairs are used, it is desirable, in additionto the outside fastenings, F F, to have tiebolts Gr G passed laterally through the tlask and fastened by suitable keys,ff.

The molding-compartments B B B B need not be in all cases exactly opposite each other, but-may be arranged as shown, for instance, in Fig. 6. Nor is it necessary `for the drags ot' the various pairs to come close together at their backs. On the other hand, the dra-gs on one side of the part a must not come solidly and continuously against the drags on the oppositeside of the part a; but a space, P, or spaces must be left, as shown, to provide for venting the gases from the sand ofthe drags,

for the present iiask involves the use of sand, and thegases therefrom in casting could not pass ott unless a space or spaces in the interior ofthe part a were provided to receive the gases. The latter issue through` the many small perforationsp pp in the shell ot' the iiask, passing into the space described in the interior ofthe part a., and thence to the outer air.

IOO

l clailn l. The combination, in a flask where sand or clay is used for molding pipes and other` castings, of the central part, a, and the side 5V parts, a a', said central part, a, having between the drags a space or spaces, for the pun pose described.

2. The combination, in a flask Where sand or clay is used, of the part a, the parts a a', and the bottom G a,having between the drags 1o therein a space 0r spaces for Venting the gases from the drags, substantially as described.
