IMPROVEMENT IN CASTING SPOONS.

Specification forming part of Letters Patent No. 4,468, dated April 25, 1846.

To @ZZ whom t may concern:

Beit known that I, JOEL HALL, 2d, of Wallingford, in the county of New Haven and State of Connecticut, have invented a new and useful improvement in the manufacture of spoons that are made of block-tin or any other fusible metal or metals, of which the following is a specification. v

The nature and object of my improvement consists in making a wire a part of the handle of a spoon by inclosing it in the metal of which the spoon is composed.

To enable others skilled in the art to make and use my improvement, I describe its construction and operation as follows, referring to the accompanying drawings as part of this specification, by which- -Figure l represents the inside of what is commonlytermed the core part77 of the mold, and Fig. 2 represents the inside of whatis commonly termed the shell part7 of the mold.

On one side of the shell part of the mold, and near the end of the part forming the handle, I leave a proj ection,across which agroove is made extending into and at right angles with that part of the mold which forms the handle. The wire having been first bent and shaped in conformity with the figure made by the part of Ithe Inoldvforming the handle and the groove aforesaid, the short part of the wire is then placed in said groove in such manner as that the long part of the wire shall lie along the center of the last-named part of the mold and free from contact therewith. A head or cap on the inner end of a pin or bolt that passes through the projection aforesaid and perpendicular to the said groove is then turned upon the wire and made fast by means of a thumb screw upon the other end of the pin or bolt aforesaid. A small pin is inserted in the said projection on the side of the groove opposite to that occupied by the first-named pin, and against which the said cap or head rests when turned upon the wire, for the purpose of preventing the revolution of the rstnamed pin when made fast by the thumb-screw aforesaid, all of which is represented in Fig. 2 of the drawings above referred to. A groove is also made upon the side of the core part of the mold corresponding and fitted tothe rstnamed groove, as represented in Fig. 1 of the drawings aforesaid. The parts are then put together for the purpose of castingin the same manner as are common molds. When the spoon is cast and the parts of the mold separated, the first-named pin is loosened by unscrewing the same, and the aforesaid cap or head is turned from off the wire, when the spoon is easily removed. The part of the wire protruding from the side of the handle of the spoon is then cut off, when the spoon is ready for bufflng or any other mode of finishing to which manufacturers are accustomed.

The advantages derived from my invention consist in the facilities afforded to the molder, the saving of stock to the manufacturer, and the consequent cheapness of the article in the markets. In attempts hitherto to secure this desirable object, the wire has been fastened to or at the eXtreme end of the handle of the spoon, where no additional strength was necessary, thus requiring that the casting in that lpart should in the rst place be very thick, and afterward reduced to a proper thickness by a tedious and expensive operation. The length of the wire from the place at which it isfastened is also an objection to this lastnamed process, inasmuch as it renders the wire more liable to motion, and thereby increases the difficulty of securing a perfect casting, for which and other reasons the said process has been found unprotable, if not impracticable, and has been abandoned.

I do not claim as iny invention the inclosing a wire in the handle of a spoon. This has already been done; but

I do claim as my invention and improvement and desire to secure by Letters Patent- The fastening or holding the wire preparatory to inclosing it in the handle of a spoon, by, to, or at either side of either part of the mold, substantially in manner and form as specified above.
