IMPROVEMENTS IN FIXING BOTTOMS TO SHEET METAL BUCKETS, APPLICABLE ALSO TO ANALOGOUS PURPOSES
Year: 1885

page_text: We LOVELL MILLREE SPACKMAN, of Haddon Lodge, Penn Fields, Wolver-
hampton in the County of Stafford, hardware merchant, and JAMES CHILTON, of
Newton Place, New Zoar Street, Wolverhampton aforesaid, iron plate worker do
hereby declare the nature of our invention for IMPROVEMENTS IN FIXING BOTTOMS
TO SHEET METAL BUCKETS, APPLICABLE ALSO TO ANALOGOUS PURPOSES and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement reference being had to the accompanying
drawings and the letters of reference marked thereon:-
.
The chief object of this invention is to simplify and cheapen the ordinary method
of fixing sheet metal bucket bottoms that is the method usually known in the
trade as
knocking up" but this invention is applicable also to fixing the tops
bottoms or ends of other articles of sheet metal.
This invention will be readily understood by reference to the accompanying
drawings, of which figure 1 illustrates the lower part of one side of a sheet metal
bucket and the part of the bottom adjacent thereto, previously to the parts being
fixed together; and figure 2 illustrates the corresponding parts fixed together.
A is the side of the bucket and B the bottom. The bottom B is first stamped so
as to form a groove a therenround and the lower end of the bucket body is then .
placed in such groove, as shewn by figure 1. The side b of the groove is next
pressed up tightly against the outside of the lower part of the body, as shewn at
figure 2, and this may be accomplished either by hand or by a wheeling or wiring
machine in a manner readily understood. Simultaneously with the pressing up of
the side b, the inner side c of the groove is also tightened up against the metal of
the body and so as to form as sharp an angle as may be convenient at the point d,
and so as, if desired, to set the lower rim of the body at an angle to the side thereof
as shewn.
We prefer to carry out our invention in the manner above-described, but figure 3
illustrates a modification of the invention and is a corresponding view to figure 1.
In this case also A is the side of the bucket and B the bottom. The bottom B is
stamped so as to form a downward flange e therearound, and is then placed in the
lower end of the body as shewn, with the lower edge of the flange projecting below
the body. The lower edge of the flange is then bent around the lower edge of

page_text: the body and against the outside thereof into the position shewn by figure 2, such
bending being performed either by hand, or by means of a machine similarly as in
wiring, in which latter case the machine may be modified somewhat for the special
purpose as will be readily understood by machinists experienced in the construction
and use of such class of machines; or the bending may be performed in any
convenient manner. In this modification the part of the flange corresponding to
the part lettered c, figure 2, is treated similarly as such part c, so that the completed
joint made according to this modification is illustrated correctly by figure 2. In
this modification, also, the lower rim of the body may be set at an angle to the side
thereof as shewn by figure 2, during the bending over of the flange, but this is not
essential, and is not a necessary result, as will be readily understood.
If a bucket, constructed in the manner above-described, according to either
modification, is afterwards galvanized or similarly treated, the molten metal of
course makes a thoroughly water tight joint around the bottom.
The method of fixing bottoms to buckets as above-described, according to either
modification, is applicable also to the fixing of the tops bottoms or ends of
other articles of sheet metal, whether circular, oval, or angular, but in the case of
rectangular tops, bottoms or ends the corners thereof should be nicked or cut away
previously to the grooves or flanges being stamped.
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. Fixing the bottoms of sheet metal buckets, and the tops, bottoms or ends of
other articles of sheet metal by first grooving such bottoms, or tops or ends, and
then tightening the sides of the grooves around the edges of the bodies, substantially
as herein described and shewn by the drawings.
2. Fixing the bottoms of sheet metal buckets, and the tops, bottoms or ends of
other articles of sheet metal by first flanging such bottoms, or tops, or ends,
outwardly, and then bending the edges of such flanges so as to be around the
exterior of the bodies, substantially as herein described and shewn by the
drawings.
