IMPROVEMENT IN APPARATUS FOR COATING METAL PLATES.

Specification forming part of Letters Patent No. l 7 1,688, dated January 4, 1876; application filed December 6, 1875.

CASE B.

-To all whom it may concern:

Be it known that We, EDMUND MOREWOOD, of Llanelly, and JOHN HENRY ROGERS, of Llangenneoh Park, near Llanelly, both in the county of Garmarthen, Great Britain, have invented an Improvement in Coating Metals; and the following is declared to be a full and correct description of the same.

Our invention relates to means for righting or putting into proper condition the oil, grease, or fatty matter which has become frothy or porous, and thereby unsuitable, and which is especially used in the'process of coating plates or other pieces of iron with tin or terne, such plates being coated with such oil, grease, or fatty matters in order that they may more readily receive the subsequent coating with Figs. 1 and 2, which rises higher than the box a; and there is a space between the two extending all around, as in Fig. 2, or at three sides only, as in Fig. 3. d are holes in the lower part of the box at, opening into the vessel b. The Wet black clean plates are introduced into the inner box or vessel a,between the pins 0, in order to be heated and greased by the flux contained therein preparatory to coating metal.

their being passed into the bath of melted The froth arising from the boiling grease flows over the top h of the inner vessel on into the outer or overflow cistern b, and, after righting itself and becoming more heavy and solid, flows back through the holes d-into the inner vessel a, provided the column of solid grease in the settling device is heavier than the column of frothy grease in the fluxbox. In the vertical section, Fig. 4. the vessels a and 1), instead of being 'one within the other, are placed side by side and connected at top and bottom by pipes h d. The operation is precisely the same as that before described, the frothy and porous grease overflowing, by the pipe h, into the vessel 12, where it rights itself and re-enters the vessel 11, by the pipe 01, in a more solid and non-frothy condition or the frothy grease might overflow into alarge gutter or pipe of anysuitable size and form, instead of a special settling-vessel.

We do not claim asettling-vessel, b, in combination with mechanical means or appliances for producing an artificial circulation of the fluid; but

We claim as our invention- The flux-pot a, overflow h, settling-vessel I). or equivalent device, and return-opening d, so

'as to produce an automatic circulation of the flux, substantially as and for the purposes set forth.
