LOUIS MARTARESCHE, OF PITTSBURG, PENNSYLVANIA.
IMPROVEMENT IN MOLDING AND CASTING PIPE.
Specification forming part of Letters Patent No. 96,131 dated October 26, 1869.
To all whom it may concern:
Be it known that I, Louis MARTAREsci-IE, of' Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Flasks and Method of Molding Pipe; andIhereby declare that the following is a full, clear, and exact description thereof', reference being had to the accompanying drawings, forming part of this specification, and to the letters of reference marked thereon, in which- Figure l represents a front elevation of' a molding-ask in an upright position upon a supporting-table provided with a stove beneath; Fig. 2, a transverse vertical section; Fig. 3, a side elevation of the same. Fig. 4 represents an enlarged cross-section of the door used for closing the bottom of the upright iiask, and small circular horizontal flask resting thereon 5 Fig. 5, a conical sheetiron chimney.
To enable others to understand, make, and use my invention, I will proceed to describe its construction and operation.
The flask A is made in two parts, held together by keys and wedges passing through lugs at the side, in the usual manner, and is to be placed in an upright position upon a cast-iron table, B, each half of the flask A resting on a curved foot, @which is pivoted to the table in such a manner as to allow the sides of' the ilask A, on the withdrawal of their attachments, to fall apart, as represented by the dotted lines in Fig. 3. Through the top of this table B is a circular hole, corresponding in size to the inside diam eter of' the ask A; and for closing this hole there is hung underneath the table a swinging door, S, provided with a central conical-shaped aperture for the reception of' the lower end of the corebar K. On the face of this door, and around the central aperture, is a projecting flange, n, for holding in proper position on the face of the door a small circular ask, T, for retaining sand, to give shape to the lower end of the pipe, the form required for that purpose being impressed in this sand by suitable patterns.
To increase the length of bearing and insure the steadiness of the core`bar in the mold, the
central aperture in the door is deepened by the addition of a surrounding ange, m, on its lower side.
The core-bar K is considerably enlarged at its bottom end, so asto form a bulb, C, which fits in the hole in the door S, and keeps the core in the exact center of the mold. This enlargement also serves another purpose, that in being below the cast pipe the said pipe, with most of its investing sand, may be drawn out of the flask together by making an attachment to the upper end of the core-bar K and raising it in a vertical line.
Below the table B, and connected therewith by means of its legs g g, so as to be portable, I have placed an open topped stove, D, provided with a grate and an opening below for the admission of air. This stove is intended for rapidly drying' the mold in the ilask A, the heat f'rom the stove being carried directly into and through the mold by means of' a short conical chimney, Fig. 5, placed with its large end over the open stove D, and the other or small end in the opening through the table B,
vor, if the door S be closed, through its opening in its center, as-Inay be found best in pracice.
Having claim- 1. Providing the flask A with curved feet c, so pivoted to the table B as to admit of the flask being opened, substantially in the manner shown and set forth.
2. Also, providing the swinging door S of the iiask A with a circular flange or rim, 11, on its face or upper side, for the purpose ot' holding in place the small ask T, as shown and described.
3. Also, in combination with the swinging door S, the use of' the small flask Tfor holding sand, to give i'orm to the lower end ofthe pipe, as described.
4. Also, the bulb or enlargement C on the lower end of the core-bar K, in combination with the ask A, provided with a swinging door, S, for the purposes hereinbef'ore set forth.
5. Also, the use of a stove, D, placed in a vertical line beneath the flask A, when so attached thereto by means of the table B and its legs g g as to be moved with the flask A, as described.
briefly described my invention, I
Louis MARTARESCHE.
