COMPLETE SPECIFICATION.
An Improved Strainer for Teapots and similar Vessels.
I, JOSEPH BROOKE of Lister's Hill, Thornhill near Dewsbury in the County of
York, Coal Miner 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 :-
My invention consists in an improved form of strainer applicable to teapots and
the like vessels employed in making and pouring off infusions which are required to
be clear, such improvements also facilitating the fixing of the strainer when applied
to existing teapots and the like.
In order to enable my invention to be fully understood I will proceed to describe
the same with reference to the accompanying drawings in which
Figure 1 represents a sectional elevation of a teapot, the improved strainer of
which is formed and fixed in position at the time of making the teapot, or in the
case of a metal teapot the improved strainer may be soldered or screwed in its
place at any time afterwards.
Figures 2 and 3 represent sectional elevations of ordinary existing teapots to
which my improved strainers are applied by means of a screw and nut attachment
and by a spiral spring respectively.
Similar letters refer to similar parts in all the drawings.
The body of the teapot is represented at A A and the improved strainers which
are formed of finely perforated sheet metal or earthenware or finely woven wire-work
at C C, the spout being represented at B B.
In Figure 2 the strainer C is held in position by means of a spindle E which is
provided at one end F with small springs which open outward when passed through
the centre hole of the existing strainer of the teapot. The spindle cannot then be
withdrawn and the improved strainer is secured upon the screwed end of the
spindle E by means of the nut G.
The washer D is placed between the flange of the strainer C and the front of the
teapot and thereby forms a joint sufficiently close to prevent the passage of tea
leaves or other solid matter into the spout.
In the modification represented at Figure 3 the strainer C is shown as being
held in position by means of the spiral wire spring J placed upon the spindle H
which is fixed to the strainer. This spring bears upon the side of the teapot at a
point diametrically opposite to that at which the spout is placed. This form of
strainer is also provided with a washer D of asbestos, cotton, or some other soft,
insoluble and tasteless packing material.
By causing the strainer to project well into the teapot I secure a much larger
effective straining surface and less pressure than when a flatter strainer is employed,
and the risk of stoppage is overcome.
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 making a teapot or a like vessel of metal or earthenware, the addition of
an internal projecting tube finely perforated, or formed of woven wire when applied
to metallic teapots.
2. In existing metallic teapots or the like, the tubular strainer represented at C
Figure 1 and fixed over the orifice opening into the spout.
3. The strainer C represented in Figure 2 and fixed to an existing teapot by
means of the spindle E, with the expanding springs F, the nut G, and the washer D,

page_text: all constructed and operating in the manner described, and as represented in the
accompanying drawings.
4. In ordinary teapots the application of the strainer C held in position by
means of the spiral spring J upon the spindle H, the flange or ring of the strainer Č
resting upon the washer D which surrounds the orifice opening to the spout, all
operating in the manner and for the purpose herein described, and as represented
in the accompanying drawings.
Dated this Fourth day of November 1892.
