`|ltiFllOVl-l'ldlNT lN THE MANUFACTURE 0l: WlRE-STRENGIHENED SIPOONS, &c.

Specification forming part of Letters Patent No. 8,102. dated May 20,' 151.

To @ZZ whom it may conceive:

Be it known that I, LUTHER BOARDMAN,

of East Haddam, in the county of Middlesex l and State of Connecticut, have invented oer- `ta1n new and useful improvements in the manufacture of spoons or their handles made of block-tin orany other fusible metal or metals,

which improvements are equally applicable 'to the construction of other handles havingwires within them; andI do hereby declare .that 'the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a perspective view of the shell and c ore parts of a mold united. Fig. 2 is a parallel perspective View of the shell ofthe inoldsnpporting Wireswithinit. i Fig. 3 is a similar View of the core part ot'themold, and Fig. 4 is a longitudinal section of the shell portion Vof the mold, Fig. 2, taken through one of the forms and showing t-he manner of carrying the wires.

The nature of `my invention refers to the eonstructionof the handle of the s'poou or other handle .having a wire inclosed within it; and it consistsin supporting the-wire withl inthe form omposing the shape ofl the haudle on points or projections inserted in or secured to one halt' of 4the mold, so that the metal will be cast or run round the wire and small apertures left in the handle by the points carrying the Wire,- whieh may afterward be lled up by separate insertion of proper material, or by dilation of the Vmetal forming the handle, prod uccd by pressure through stamps or otherwise. Y i

Tol enable others skilled in the art to make .andV use my invention, I will proceed more fully to 4describe it-l A represents what is uszally .termed `the ."shell portion of the mold used in casting spoons,.and B the core part of the same.` The construction .of these parts'is similar tothose in use under protection of a patent granted lne, or need not necessarily differ (materially) from moldsin ordinary use.

. l VThe parts or blocks A 13 forming the mold are shown in drawings' constructed with, two forms for casting spoons in pairs; Ibut one forni only, or three or more, may be used ina singlemold, if preferred.

a a of eitherbloch composes the' main gate .or channel, through which Ithe fused metahis run, having branches b b b b b b from it to the space left by either block inv their interior Y i when united correspondingto the shape of vthe spoon to be made, and which is composed by the several indented portions, c c e e c c, and projectingparts dd ofthe forms in both Having thus .sufficiently described a m'old used in making spoons, I will now explain my improvements applicable to theV construction of their handleswhen wire (for giving additional sirengt'h and cconomizing stock)` inelosed within the handle is desired to be used. Y

In order that the wire intended to be inclosed may be kept free fnom contact with the surfaces of the forms, so that the fused metal will run round it, -an extensionot-thewwire shitherto has been held necessary, passing either th rough the end, face, or sideof the handle, and secured on the outside of the form,

r.so that the casting,when taken from the mold,

has one end of the Wire projecting' from it,

which is afterward cut off, butv the end of the A and may be of a dovetail torni at their ends,` in which are slits or apertures; and c e e e are points or project-ions secured to the block,

which may be made of Wedge shape and used for entering the slits in the ends ot' the Wires C C, so that the points cl e e e carry or support the wire free from contact with the'surfaces ofthe forms, and round which theinetal will run, inclosiugthe wire within the handle, and leaving onlyT small cavities or spaces in thc, back of the handle where the points e e e'e are secured tothe block, which may be filled in by the usual marks or stamps pressed on the back of the haudle,which, by the dilation produced through Jthe pressure employed, will cause the czwitics'to be iilled in by 'the metal composing the handle; and the inclosed Wire 'rendered invisible and exempt from corrosion; also, much time will be economized in adopting this improved process of inserting the Wires over the ordinary modes employed, which, in the exaetness required to adjust the wires centrally in the f0rms, occupies considerable timeI to arrange, rsind by exixployment of 'suitable machinery to luy the wiresj l 011 the points e e e e the time consumed will be further economized,l which not only facilitates the manufacture but also (where metal liable to oxidize when heated is used in forming the handles) the time 4saved by my improved pro quired exact length Within the handle by supporting it' on points secured-t0 the mold', and projecting midway or partly into the forml LUTHER BO ARDMAN.
