We THOMAS MINNIS of Bickford House, Heath Town, Wolverhampton Stafford,
Galvanized Iron Manufacturer, & EDWARD INGRAM, 5 Bull Street, Harborne,
Birmingham do hereby declare the nature of our said invention for "IMPROVE-
MENTS IN AND CONNECTED WITH GALVANIZING BATHS," to be as follows:-
For the purpose of my invention the sheet iron is passed through between
rollers in the ordinary manner and by means of a guide, is passed on from thence
between one of them and on another roller and delivered out of bath from between
those two rollers.
The latter rollers are always kept in such position that their centres are slightly
below the level of the metal in the bath and the adjustment of the rolls may be
effected by means of levers and weights or if preferable by levers and screws.
By this invention three rollers are used whereby among other advantages, a
saving of flues is effected on the delivery side of the bath.

Improvements in and Connected with Galvanizing Baths.
We THOMAS MINNIS of Bickford House, Heath Town, Wolverhampton, Stafford,
Galvanized Iron Manufacturer; and EDWARD INGRAM of 5 Bull Street, Harborne,
Birmingham 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 :-
For the purpose of our invention the sheet iron is passed through between
rollers in the ordinary manner and by means of a guide is passed on from thence

page_text: between one of them and another roller and delivered out of the bath from between
those two rollers. The latter rollers are always kept in such position that their
centres are slightly below the level of the metal in the bath and the adjustment of
the rolls may be effected by means of levers and weights or if preferable by levers
and screws.
By this invention three rollers are used whereby among other advantages, there
is a great saving of Spelter and Ammonia as compared with other methods; and
the saving of labour etc by this system is a considerable item.
The manner of carrying out this invention will be understood by reference to the
annexed drawings in which Figure 1 is a part sectional elevation of a galvanizing
bath or tank for holding the spelter and in said bath A, three rollers B, C, D, are
placed, the rollers B and C being so arranged that their centres or axes are
slightly below the level of the surface of the spelter. As the said level varies the
rollers are made capable of adjustment by means of screws W or otherwise.
G is a lever pivotted at H for raising or lowering the roller B by means of the
pivotted arm I, and J is a similar lever for adjusting the roller C to which it
is connected by the pivotted arm K. The said levers G. J may be operated by
weights LM, or in any convenient manner.
N, N are flues for heating the bath A.
Figure 2 is a plan of the galvanizing bath or tank with the weights and levers
removed.
P is the driving shaft to which is fixed the gear wheel which operates the
pinion R on the spindle of the roller C. The spindle of the roller C has also fixed
to it the wheel S gearing with the wheel T fixed on the spindle of the roller B.
The sheet iron to be galvanized enters through the flux box U and is passed
between the rollers C and D, it is then bent or led upwards by the guide V and
passed between the rollers B and C for delivery.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
The employment of three rollers in a galvanizing bath adjustable in the manner
herein described for the purpose set forth and substantially as shown in the
annexed drawings.
