COMPLETE SPECIFICATION.
Improvements in Sheet Metal Buckets, Coal Scoops, Round and Oval
Baths, Watering Cans, Boiler Fillers, and other like vessels, and
in the Manufacture of the same.
We, JAMES BRATT and ALFRED BRATT, of Clarence Street Works, Wolver
hampton, in the County of Stafford, Manufacturers, 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 has reference to galvanized iron and other sheet metal buckets,
coal scoops, round and oval baths, watering cans, boiler fillers and other like vessels
and this invention consists in constructing the bottoms of the said vessels and
securing them to the body part of the vessel as herein described whereby we avoid
the usual bottom seam where the bottom of the vessel joins the sides (which seam
often leaks) and we considerably strengthen the lower part of the said vessels.
We will describe our invention by referring to the accompanying drawing on
which Figs. 1, 3, 5 and 7 each represent a sheet metal bucket without its ears and
handle in sectional elevation shewing the different stages in the securing of the
bottom to the bucket in accordance with this invention the finished bucket being
shewn by Fig. 7; Fig. 2 shews an enlarged view of the joint of the bucket bottom
to the bucket body at the stage shewn by Fig. 1; Fig. 4 is an enlarged view of
the same joint at the stage shewn by Fig. 3; Fig. 6 is an enlarged view of the said
joint at the stage shewn by Fig. 5 and Fig. S is an enlarged view of the finished
joint of the bucket as shewn in Fig 7.
In carrying out this invention we make the bucket bottom B₁ in the form of a
shallow vessel with sides B2 extending upwardly for say about one inch more or less
the top being flanged outwardly at the outer portion of this Hange being turned
upwardly again at 6 thus forming a kind of rebate all round the top of the shallow
vessel forming the bucket bottom; this will be clearly understood by an examination
of Figs. 1 and 2. This said shallow vessel B B for forming the bottom of the
bucket can readily be stamped by dies of suitable shape as will be well understood.
We flange outwardly the bottoin edge of the body A of the bucket at a this
flange a being of a size to fit in the enlarged rebated top part of the bucket
bottom B1 B2 as shown in Figs. 1 and 2. We then close down this flange on to
the flange a thus gripping the flange a between the flanges as shown in
Figs. 3 and 4. This as will be readily understood can be easily effected by chucking
the bucket in a lathe and turning down the flange 62 by an ordinary roller spinning
tool. We then turn this compound flange a upwardly against the body A of
the bucket so that the joint now has the appearance represented by Figs. 5 and 6
the compound flange ba¹² forming a shoulder 3 for the top of the usual hoop C
This closing of
of the bucket to abut against when the hoop is fixed thereon.
the compound flange &₁a' against the bucket as shewn in Figs. 5 and 6 can be
readily accomplished by placing the bucket upon a chuck in a lathe so as to form
a bearing inside the bucket and then turning over as above described the compound
flange baby means of a roller spinning tool as will be readily understood and
this tool is pressed sufficiently hard against the compound flange bab² so as to
thoroughly squeeze the parts of the same together and against the body of the
bucket so that the finished joint will have the appearance shewn in Figs. 7 and 8.
This compound flange babe strengthens the lower part of the bucket and as there
is no sea round the extreme bottoin of the bucket there is no possibility of the
bucket leaking at that part.
The method above described and illustrated on our drawing of securing to the
body of the bucket the shallow vessel B' B² forming the bucket bottom is what we

page_text: have found to answer well in practice but it is to be understood that we do not
limit ourselves to the precise.method above described and shewn of forming the joint
as it will be evident that this method of forming the joint may be modified without
departing from the nature of our invention. This invention is applied to coal
scoops, round and oval baths, watering caus, boiler fillers and other like sheet metal
vessels in the manner herein before described with reference to buckets.
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 :-
1
1. Making sheet metal buckets, coal scoops, round and oval baths, watering cans,
boiler fillers and other like sheet metal vessels as herein set forth so as to avoid the
bottom corner joint and so as to strengthen the lower part of the said vessels, that
is to say, making the bottom of any of the said vessels in the form of a shallow
vessel with upwardly projecting sides flanged at the top and connecting the said
flanged top to the flanged bottom edge of the body part by lapping and folding the
one within the other forming a strengthening rib around the lower part of the said
vessel some little distance above the extreme bottom of the same substantially as
set forth.
2. The herein described improved sheet metal buckets, coal scoops, round and oval
baths, watering cans, boiler fillers and other like sheet inctal vessels having their
bottoms formed and secured to their bodies in the manner substantially as herein-
before set forth and denoted under Claim 1.
Dated this 27th day of July 1893.
