CASTING FAUCETS.

Specification of Letters Patent No. 20,395, dated May 215, 1858.

To all whom it may concern:

Be it known that I, OLIVER T. VVooD, 0f Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and Improved Mode of Constructing or Manufacturing Faucets; and I do hereby declare thatthe following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, is a transverse section of a mold with the faucet therein, a?, ag Fig. 2 indicates the plane of section. Fig. 2, is a longitudinal central section of ditto or an inl ternal view of one-half or part of the mold showing the cores entire and the faucet bisected longitudinally. Fig. 3, is a plan or top view of the mold.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to an improved mode of constructing faucets and consists in placing the spigot of the faucet within a mold which is formed for casting the body or tube of the faucet, so that the body or tube of the faucet may be cast around the spigot and the latter thereby fitted properly in place without any after work or finishing whatever, the spigot being properly finished before being placed in the mold.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A represents a mold which may be constructed of metal and of a form corresponding to the desired form of the body or tube of the faucet to be cast. of two parts a, o, each attached to a stock B, the stocks when the two part-s of the mold are in contact being secured together by a screw bolt c', one or more, which in addition with a cramp screw d, causes the two parts of the mold to be kept firmly in contact, see Fig. 3.

C, represents the spigot of the faucet which is fitted within the mold A, as shown in Fig. 2. The portion of the spigot within the chamber of the mold and which portion is to be inclosed by the casting, is of spherical form and provided with one way or passage e. The mold is provided with the usual or necessary vents 7, and the aperture g, for the induction of the melted metal is placed nearly in line with the shank 7L, of the spigot, see Fig. 2.

The mold is formed D, E, represent cores. These cores are formed of rods or wire of proper shape and size corresponding of course to the desired form of the interior of the body or tube of the faucet. The rods or wire which form the cores may be attached to handles F, F.

The spigot C, is perfectly formed or completed previously to being fitted within the mold A, and when the spigot is fitted within the mold, the cores D, E, are adjusted into the ends of the mold, the ends of the cores passing into the ends of the way or passage e, of the spigot, as shown clearly in Fig. 2. The melted metal Vis then poured into the mold through the aperture g, and the body or tube G of the faucet is cast around the spigot. The cores are then withdrawn, the two parts of the mold detached, and the faucet removed from the mold. The body or tube G, of the faucet contracts suiiiciently in cooling to allow7 the spigot to turn freely in the tube.

By this improvement faucets may be constructed very expeditiously and with but comparatively a small amount of labor, as the spigots do not require to be fitted to the tubes. Any of the metals employed for such purposes may be used for the faucets. The portion of the spigot within the tube G, may be of spherical form as shown, or of conical form.

I do not confine myself to any particular shape of any of the parts.

Another advantage attending this improvement is, that the spigots will in every case be properly and snugly fitted in their tube-s. In faucets constructed in the usual way the spigots are frequently imperfectly fitted and the faucets are nearly useless, entirely so if used for drawing thin fluids.

Having thus described my invention I do not claim as novel the faucets in themselves considered, or, as new articles of manu facture, but

`What I claim as new and desire to secure by Letters Patent, is:-

Constructing faucets by placing the spigots within a mold formed for the tubes of the faucets and casting the tubes around the spigots substantially as herein shown and described.
