PROVISIONAL SPECIFICATION.
Improvements in the Construction of Aquariums.
I WILLIAM CUTLER, of Cannon Works, 75 Constitution Hill, Birmingham in the
County of Warwick, Manufacturer, do hereby declare the nature of my said invention
to be as follows:-
The object of my invention is to effect improvements in the form and construction
of aquariums.
My invention consists of two flat pieces of glass, each forming a large segmental
portion of a disc, a small segment being removed from the upper part, the upper
edge forming the horizontal chord of the segment. These segmental pieces are
placed a certain distance apart, and parallel to each other. The sides consist of
two pieces of glass, bent to a circular form, corresponding to the form of the
segments. The bottom is formed of metal, and is also curved to correspond with
the segments.
The segmental pieces of glass, the metal bottom, and the two curved glass sides
(together forining a portion of a cylinder) are held together by metallic mountings
and supported by suitable feet or other supports.
The metallic bottom is useful and convenient for drilling and fitting pipes for
fountains and taps for drawing off the water &c.
In some cases I form the sides and bottom of a single piece of glass bent to a circular
form.
The metallic mountings are so formed as to securely retain the cement, or other
plastic material, for rendering the aquarium watertight.

COMPLETE SPECIFICATION.
Improvements in the Construction of Aquariums.
1, WILLIAM CUTLER, of Cannon Works, 75 Constitution Hill, Birmingham, in the
County of Warwick, Manufacturer, do hereby declare the nature of my 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 my invention is to effect improvements in the form and construction
of aquariums.
My invention consists of two pieces of flat glass, each forming a large segmental
portion of a disc, approximating to a circular form; a small segmental portion being
removed from the upper part; the upper edge forming the horizontal chord.
The flat pieces of glass are placed in a vertical position, a certain distance apart,
and parallel to each other. The flat pieces of glass are then fitted with end pieces,
bent to the form of the flat pieces. The bottom is preferably formed of metal, and is
curved to the form of the flat pieces of glass.
And in order that my 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 perspective elevation, and Fig. 2. is an end view of my invention.
a is one of the flat segmental pieces of glass, a similar piece of glass forming the
back. bbare the sides or ends, formed of glass and bent to correspond to the
form of the segments. c is the metallic bottom. d d are metallic beadings, by
which the several parts of the aquarium are secured together; cement being used

aquarium.
The beadings and other fittings are usually ornamented in various ways, and the
metallic bottom is useful and convenient for drilling and fitting pipes for fountains
and taps for drawing off the water &c.
In some cases I form the sides and bottom of a single piece of glass, bent to the form
of the flat portions.
Although I prefer keeping to a true circle in the construction of my invention, it is
...obvious that an exact adhesion to that form is not essential, and that a slight departure
therefrom may be adopted.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In the construction of aquariums, the combination of two flat segmental pieces of
glass a, two bent pieces of glass bb, a metallic bottom plate c, severally united by
metallic beading d à, and mounted on suitable feet ee or other supports, the whole
being rendered water-tight by cement, substantially as hereinbefore described and
illustrated by the drawings.
2. In the construction of aquariums as aforesaid, the combination of two flat
segmental pieces of glass a; a single piece of glass bb forming ends and bottom in one,
united by metallic beadings d, and fitted with feet ee, or other suitable supports,
substantially as herein before described and illustrated by the drawings.
3. The general construction, arrangement, and combination of the several and
· respective parts, together forming my invention of improvements in the con-
struction of aquariunis, substantially as hereinbefore described and illustrated by the
⚫ drawings.
