We, JOSEPH LAW and HENRY LAW of the firm of Samuel Law and Son, Moorland
Mills, Cleckheaton in the County of York, Card Makers, do hereby declare the nature
of this invention to be as follows:-
This invention relates to improvements in apparatus for purpose aforesaid for which
Letters Patent No. 162 dated 14th January 1880 were granted to present applicants
and the object of this our invention is to prevent or reduce to a minimum the
formation of scum and oxydation of the surface of the molten lead in the wire
heating bath and thereby to reduce waste of lead to a minimum.
For purpose aforesaid, according to this our said invention, we so hinge the lid or
cover of the bath containing the molten lead, that the lid fits into the top of the bath,
and we combine with the underside of the said lid, a covering or facing of asbestos,
felted or woven fabric, the object being to exclude far as may be the entrance and
contact of air with the molten lead, and which object in practise we have heretofore
in part attained by the use of a covering of charcoal spread over the surface of the
molten lead.
The combination of a close fitting lid faced with asbestos, and the charcoal dressing,
we find give the best results, there being as little space left for entrance of air as is
consistant, with necessary aperture for admission of the wire to the bath.

We JOSEPH LAW and HENRY LAW of the firm of Samuel Law and Son, Moorland
Mills, Cleckheaton in the County of York, Card Makers do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to improvements in apparatus for purpose aforesaid for which
Letters Patent No. 162 dated 14th January 1880 were granted to the present applicants
and the object of this our invention is to prevent or reduce to a minimum the formation
of scum and oxydation of the surface of the molten lead in the wire heating bath and
thereby to reduce waste of lead to a minimum.
For purpose aforesaid, according to this our said invention we so hinge the lid or
cover of the bath containing the molten lead, that the lid fits into the top of the bath
and we combine with the underside of the said lid a covering or facing of asbestos,
felted or woven fabric, the object being to exclude far as may be the entrance and
contact of air with the molten lead and which object in practice we have heretofore
in part attained by the use of a covering of charcoal spread over the surface of the
molten lead.
The combination of a close fitting lid faced with asbestos, and the charcoal dressing
we find give the best results, there being as little space left for entrance of air, as is
consistent with necessary aperture for admission of the wire to the bath.
Such being the nature and object of this our invention the following is a complete
description of same reference being had to the accompanying drawings:-
Fig. 1. is a sectional elevation of the bath with our improvements applied
thereto.
According to this our said invention we so hinge the lid or cover 1 of the bath 2
containing the molten lead 3, that the lid 1 fits into the top of the bath, and we com-
bine with the underside of the said lid 1 a covering or facing of asbestos, felted or
woven fabric, secured to the lids by pin 4ª, the object being to exclude far as may be
the entrance and contact of air with the molten lead 3, and which object in practice
we have heretofore in part attained by the use of a covering of charcoal 5 spread
over the surface of the molten lead 3.
The combination of a close fitting lid 1 faced with asbestos 4 and the charcoal
dressing 5 we find give the best results, there being as little space left for entrance of
air as is consistent with necessary aperture for admission of the wire to the bath,

tion, and in what manner the same is to be performed, we declare that what
we claim is :-
