@tutti ALBERT HALLOWELL, OF LOWELL, MASSACHUSETTS.
Letters Patent No. 84,112, (lated November 17, 1868.
` IMPROVEMENT IN G-S AND STEAM-FITTINGS.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it ma/y conce/m Be it known that I, ALBERTHALLOWELL, ofllowell,
in the county of Middlesex, and State of Massachusetts, have invented certain new and useful Improve ments in the Fittings which are Used in Connection with Gas and Steam-Pipes or Fixtures, or the pipes or fixtures which are used for conveying water or other fluids, and in the method or process of making such fittings, of which the following is a full, clear, and exact description, which will enable others skilled inthe art to make aud use my invention, reference being had to the accompanying drawings, making part of' this specication, in which- Figure l is a vertical central section of my improved apparatus, with a portion of afitting, called a valvestand, formed within.
Figure 2 represents a top view of my improved apparatus, as it appears when ready to receive the meltedy metal, to form a valve-stand.
Figure 3 is a bottom-side view of a detached forming-die, H, seen 'm fig. l.
Figure 4, an edge'view of fig. 3.
Figure 5, is a bottom-end,
Figure 6, a top-end, and
Figure 7, a side elevation of one of the valve-stands I, seen in fig. l.
Figure 8 is a plan or top view of' the plate or disk G, and the central screw-core J, seen in fig. l.
Figures 9 and l0 are central longitudinal sections of apparatus, forming parts a-,which constitute the venting-chamber or top of an oil-can, a section of a portion of' which and the parts a are shown in Figure l1.
' rlhis invention consists in making or forming finished fttin gs, which are called gas-fittings and steam-fittin gs, and of making or forming parts ofA such fittings, which, when combined, ferm whole iittin gs, and which are used for connecting' pipes or fixtures for conveying gas, steam, water, or other iiuids, and for controlling the action, pressure, or force of such fluids passing through 'such pipes or fixtures, by casting such finished ttings, or parts of fittings, in moulds, constructed and arranged substantially as hereinafter described.
This invention has for its object to materially cheapen or reduce the cost of steam, gas, and other fittings, and
to render them less liable to corrosive action, and available for ``re-working after they are worn out, and ata trifi'mg expense.
In making steam, gas, and other fittings, or parts of such fittings, (and as, in the present case, a stand, which forms part of a globe-valve, and which stand is an expensive and difficult part to finish in the common Way of turning, ling, and cutting the external screws, and'tapping the internal screw-threads accurately,) I first prepare a suitable mould, A, the inside of which, at the lower end, l, and at about the middle, el, has screw-threads out, to form the screw-portion, b and d,
lof' the stand I. The restof the external surface of such stand, including the nut-portion N, is formed by a die, H, fitted into a cavity in the mould, between the screw-portion b and d.
A screw-core, J, fitted and fastened to a disk or plate, G, passes upward through the die H and the mould, the lower end of which is closely fitted inside of a rib o1' flange, f, and squared and fitted tothe top of the disk H, inside of the said rib, thus keeping all 'the parts in their proper central position.
The upper endpof the screw-core J is reduced in diameter downward to a little belowthe top of the screw-portion d', so as to form a close, round bearing, and a guide for the valve-spindle, which is turned to fit the same.
When a fitting, or a part of a fitting, is to be cast or formed, (in the present case, a valvestand,) the die H is placed within the mould A, the handle or a rod,
g, passing in through a hole in the joint'of` the mould. The screw-core is passed upward through the centre, bringing the top side of the disk G and the bottom end of the mould into close contact. The mould isl then clamped together, and melted metal poured in at the flaring annular gate h, aroimdthe top end ofthe screwcore J.
As soon as the fully-formed fitting is suflciently cooled or hardened, the disk is rotated or turned, to withdraw the screw-core, the mould is parted, and the stand l is removed, with the die H, which holds it, and out of which it drops readily by a slight rap on the die, or by holding the die in the right position.
Each operation of casting and removing a perfectlyformed stand lis performed in the same manner, as fast as cooling and pouring can be effected.
The mould should be of iron, or of some other metal which is harder or fusible at a higher degree of heat than the metal used for forming or casting stands yor other fittings. Otherwise the mould might be in iured by the highly-heated and fluid metal.
Handles B, at each side of the mould, are for onerating or adjusting the parts when desired.
Another expensive and. difcult fitting to make and finish is shown in figs. 9, lO, and 11. These moulds A are constructed and operated in about the same manner as in casting the valve-stand, only each of the portions c,-which form parts of a venting-chamber or top to an oil-can, is cast in a separate mould, formed for that purpose, and, after beingr cast, one is placed in the end of the other, as shown in iig. ll, each portion heilig cast in a finished state, requiring no further operation to fit them for use. except the removal of' the gate-portion h.
These parts a are applied to the top of anoil-can, and the space k filled with solder, which holds all th parts firmly together:
Either of the'ttings, or parts of fittings, herein de- A scribed, or other fittings, can be made, by my improved' The mould or moulds, constructed and arranged method 0r process, :Lt less than one-fourth, and some substantially as described, for the purpose of forming kinds of fittings at less than one-tenth, the cost of the finished fittings, or parts of fittings, as and for the pursitme 01' similar fittings made by casting in sund, and pose specified.
