SPECIFICATION forming part of Letters Patent No. 656,502, dated August 21,1300.
Original application filed March 24, 1900, Serial No. 9,983. Divided and this applioation'filed June 11,1900.
' Serial No. 19,832. (No model.)
To (If/Z wit/0112 it may concern.-
Be it known that I, EDWARD I. BRADDOCK, a citizen of the United States, residing in Winchester, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Galvanizing Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like letters and numerals on the drawings rep- IO resenting like parts. 1
This invention relates to an apparatus with which iron or steel strips, sheets, wires, due, may be efliciently and economically galvanized by the method disclosed in United States I5 Patent No. 645,520, granted to me March 13,
The object of the present invention is. to 1 provide apparatus with which the surface area of dross through which the iron or steel strip ispassed is restricted and the dross substantially as fast as formed is continuously removed during the process of galvanizing from the portion oi the surface of contact of the zinc -bath with the lead-bath 2 5 through which the metal strip is passed. For this purpose I employ a substantially-wide kettleor vat provided at one side with means, such as a partition-wall to form a substanti ally-narrow eutrance-cham her for the sheets, &c., and a substantially-wide chamber and provide within the wide chamber, near the opposite side of the kettle, a bar which is secured to the end walls of the kettle and co.- operates with the said end walls and with 3 5 one side of the kettle to form a substantiallynarrow outlet passage-way forthe sheets,&c., and also provide the kettle intermediate of the narrow entrance-cha1nber and the said outlet passage-way with means arranged to to guide the sheets, &c., continuously or in one direction from the entrance-chamber through the kettle and into the narrow outlet passageway.
In order to practice the process above re- 5 ferred to with this present apparatus, the wider chamber of the kettle contains a bath of zinc or its alloys resting on a bath of lead or its alloys, which latter extends up into the entrance-chamber and also partially fills the ;0 narrow outlet passage-way,the remaining portion of said outlet passage-waybein g filled by the zinc or-its alloys floating above it on the lead-bath, so that as the portion of the galvanizing-bath within said passage-way is used up in the process ofgalvanizing it is continuously 5 replenished from the other portion of the galvanizing-bathoutside of said passage-way, while at the same time the dross formed in said passage-way is continuously removed during the galvanizing process and substan- 6o tially as fast as formed from the surface of contact of that portion of the galvanizingbath and of the lead baththrough which the metal strip, &c., are passed. The dross formed in the outlet passage-way is removed by the passage of the metal strip,which creates a current or flow of metal and draws the small amount of'dross. formed by each metal strip up out of the said passage-way and into the body of the galvanizing-bath outside l ofsaid passage-way, in which bath said dross settles and can accumulate without interferenee with or detriment to the galvanized strip, sheet, &c., and is prevented from flowing back into the passage-way by the walls of the same, which effectively cut off the zinc in the passage-way from the dross outside thereof.
Figure 1 is a transverse section of an apparatus embodying the invention, and Fig. 2 8a a longitudinal section of the apparatus shown in Fig. 1 on the line 2 2 looking toward the right. p v
Referring to the drawings, a represents a kettle or vat provided at one side with means (shown as a partition-wall cl) for separating the upper portion of the kettle a into a-substantiaily-narrow entrance-chamber e and a substantially-wide chamber f, which contains within it, near the opposite side of the kettle, go a bar or piece 12, provided at its ends with flanges 13, by means of which the said bar may be tightly secured to the end walls ofthe kettle, below its upper edge. The bar 12 cooperates with the end walls andiwith one side wall of the kettle to form a substantiallynarrow outlet passage-way for the sheet, &c., and in practice the kettle a contains a bath gvof lead or its alloys and a bath h of zinc or its alloys, which latter bath floats on the portion of the lead-bath within the wider chamber f. The bar 12 is secured to the end walls of the kettle a, with its upper edge below the .upper surface of the zincor galvanizing bath and its lower edge below the surface of the lead-bath, and the kettle is provided intermediate of the entrance-chamber e "and the narrow outlet passage-way with suitsite side walls of .the kettle, and an upper set 18 of guiding-strips, secured at one end to the bar 12 and having theirother end resting against the partition-wall d. The lower set of guides prevents the sheet scraping on the bottom wall of the kettle, and the upper set prevents the sheet floating in the lead out of v the path of the outlet passage-way.
YVith the apparatus herein shownthe sheets, strips, &c., to be galvanized are passed down through the entrance-chamber e into the leadbath and continuing in the same direction pass through the narrow outlet passage-way formed by the bar 12 and three walls of the kettle. The amount of dross formed in the and draws the small amount of dross formed by each strip up out of the outlet passage- .way and into the body of the galvanizing- I bath outside of said passage-way, in which the dross settles and accumulates, as indicated by 10 in Figs. 1 and 2. The bar 12,
4o forming one side wall of the outlet passageway, effectively cuts off the dress 10 and prevents it from flowing or running back into the outlet passage-way. It will thus be seen that the amount of dross formed in the outlet passage-way is restricted in area and is by the action of the metal sheet, &c., continuously removed from between the surface of the zinc and lead at the place where the metal sheet passes from the lead-bath into the zinc, and as the dross accumulates outside of the bar 12 it automatically feeds the zinc into the outlet passage-way.
This application is a division of my application, Serial No. 9,983, filed March 24, 1900.
I claim- An apparatus for galvanizingstrips, sheets, &c., comprising a substantially-wide kettle or vat, means within it at one side thereof to form a substantially-narrow entrance-cham-.
but below the upper edge thereof and at a substantially-wide distance from the said narrow chamber to form a narrow outlet passage-way for the said sheets closed at its sides and ends, an'dguides intermediate of the said entrance-chamber and said outlet passageway arranged to direct the metal sheets, &c., continuously or in one direction through the kettle and into said outlet passage-way, substantially as and for the purpose specified.
In testimony. whereof I have signed my name to this specification in the presence of" two subscribing witnesses.
