` IMPRQVEMEI IN MOLDSFOR CASTIVIING MACKERELJIGS.
The Schedule referred to in these Letters Patent and making part of the same To all -pe/rso'ns `to wltomrtlwse presentsmay come:
Be it known that I, GREENLEAF BAssEzrr, of Taunton, of the county of Bristol, of the State of `Massaolmsetts, have invented a jnew and useful improved Moldfor Oasting Maekerel-Jigs,7 or metallic weights or sinkers upon fish hooks;` and yI do hereby declare the same to be fully described inthe following speci- Vioaton, and represented in" the accompanying drawing, of whichi Y Figure 1 is an elevation;` L Figure 2, a top view; y i
Figure 3, av bottornview'; and i l Figure 4, a rear eleva' -'on of the mold, as open. Figure 5 is a transverse section of it, as closed, the
section representing the position of a fish-hook as arranged in the 1eadmatrix,`and held"iu,place by the. spring jaws, hereinafter described. .v
i The mold is exhibited as made `iu'halves or parts,
A B, hinged together, as shown at a, and being each furnished with a handle, C. Y
'Each of such halveszis exhibitedV as having two long cavities, b i), 'each having a sprue or induct, c.v
In the upper part of each oil-such cavities is a proy -jection, d, which is intededto'aid in forming an eye orhole through the ,weight 'orfcastingv The lower part of` veaeh matrix portion terminates in semi-cylindrical passage, V,leadin'g ont of the lower edge of the mold, and being destined to t the shank of a fish-hook, h, when introduced into tgand the cavity, in manner as represented.`
In order to support the hook so introduced, and to hold it in its proper position relatively to the parts for l forming the eyeofthe weight that may be cast upon the hook, `I provideeaeh of the weight matrices with la pair of spring nippers or jaws, i, fixed to the mold, and arranged with the matrix, and formed in manner as shown. v
" The part or parts of the y ho'ok that arel extended i out of the mold are inserted between the jaws, and
they are to be sprung upon the hook, so as tp hold itin its correct position while metalis being pourediuto the'moldand about the-shank vof the hook.
' What I claim isi 'The arrangement and combination of the pair of jaws or the hook-holder t' 'i with the mold for casting a weight on the shank'of the hook, and forming such weight with an eye', as described( GREENLEAF BASSETT.
