PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Lamp Vases.
We, JOHN HENRY WOODROFFE, of 11 Church View, Witton Lane, Aston,
Birmingham, in the County of Warwick, and JOHN WILLIAM BERNARD
WRIGHT, of the firm of Wright & Butler, Limited, Lamp Manufacturers, of New
John Street West, Birmingham, aforesaid, Managing Director do hereby declare
the nature of our said invention to be as follows:-
The object of our invention is to effect improvements in the manufacture of cast
metal lamp or other vases, whereby the cost of production may be considerably
reduced.
In carrying out our invention instead of casting the vase in one part making it
hollow by the usual expensive method of laying in a sand case we cast the vase
in two parts, which we cause to meet together in vertical lines, so that, when
fitted together, they form the complete vase for enclosing the oil container, or for
other purposes.
The two sides of the vase are formed so as to exactly mitre together, and their
lower ends are formed with lugs, having inclined meeting surfaces.
A screw bolt
A nut
is passed through these lugs, and also through the upper part of the stem.
is fitted at each end of the bolt. When screwed up the vase is firmly and securely
held together, and requires no further fitting.

Improvements in the Manufacture of Lamp Vases.
We, JOHN HENRY WOODROFFE, of 11 Church View, Witton Lane, Aston,
Birmingham, in the County of Warwick, and JOHN WILLIAM BERNARD
WRIGHT, of the firm of Wright & Butler, Limited, Lamp Manufacturers, of
New. John Street West, Birmingham aforesaid, Managing Director do hereby
declare the nature of our said invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
The object of our invention is to effect improvements in the manufacture of cast
metal lamp or other vases, whereby the cost of production may be considerably
reduced.
And in order that our said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings in which similar letters of
reference indicate corresponding parts.
Fig. 1 is a sectional elevation, and Figs. 2 and 3 are sections on the line 1-2 of
Fig. 1.
Instead of casting the vase in one part, making it hollow by the usual expensive
method of laying in a sand core,' we cast the vase in two parts, as shown in
Fig. 1, a being one half, and the other half. c is the ordinary cover and d the
stem or stand. e is a tongue formed in a fitting into a rebate in b.
In Fig. 2 the lower end of a is shown, on the line 1-2. ff are the lugs,
on each side of the slot g, provided for the reception of the screw h, or its
equivalent.

page_text: In Fig. 3 the lower end of b is shown, on the line 1-2. f1f1 are the lugs, on
each side of the slot g', through which, the screw passes.
The two sides a and thus meet together in vertical lines, and, when fitted
together, they form the complete vase for enclosing the oil container, or for any
other suitable purpose..
The screw bolt his carried down through the slots and gl and the upper part
of the stem or stand d. When screwed up the vase is firmly and securely held
together, and requires no further fitting. The lugs ff1 may be cast solid, and
holes drilled through them to receive a screw or stud.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
1. In the manufacture of lamp or other vases, the method of forming the
same in two parts a and b, having lngs ff" at the bottom of each part: tongues e
and corresponding rebates for the same: the two sides being held together, and
to the stem d, by a bolt and nut or their equivalent, substantially as herein
before described and illustrated by the drawings.
2. The improvements in the manufacture of lamp or other vases, substantially
as herein before described and illustrated by the drawings.
