Improvements in Stands for Supporting Strainers.
We, JAMES STURROCK, of Seacraig, Cashier, Dundee Advertiser Office, and
GEORGE DUNCAN MACDOUGALD, of 3 Youngsdale Place, Analytical Chemist,
both of Newport, in the County of Fife, N.B., 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:—
Our invention comprises various improvements in stands for supporting strainers,
including improvements in the design and construction thereof.
The accompanying sheets of explanatory drawings illustrate methods of carrying
out our invention.
Figure 1. is an illustration of the stand, showing it carrying or supporting a
strainer,
Figure 2. shows the said stand folded up,
Figure 3. illustrates another modification carrying a strainer, and
Figure 4. shows it folded up, while
Figure 5. shows a third modification provided with stays for adding to the
strength of the combination.
In these drawings the same reference numerals are used to mark the same or like
parts wherever they are repeated.
In carrying out our invention according to the first modification (see Figures 1.
and 2.) we employ eight wires 6. of rectangular section-either straight, as shewn
in the drawing, or curved as in Figures 3. and 4.—and combine them together in
the manner shewn by means of the hinged or flexible joints 7. 8. and 9.
Suitable
hooks or clips 10. are also provided, in order that the loops 11. of the strainer 12.
may be attached; or otherwise the hooks may be dispensed with and the strainer
suspended in any other convenient manner, such as by putting the loops over the
apices of the appliance. The effect of the strainer and contents as it hangs from
the apices, is to contract the upper portion of the stand, and in virtue of the
particular jointing, design, and construction as illustrated, it not only stiffens the
whole structure, but tends in like manner to contract the lower points or legs, and
thus adds to the stability. One of the special features of this modification is the
twist given to the wires, said twist amounting to one quarter turn, or thereby; the
effect of which is to add to the strength of the combination. 13. is the basin for
receiving the liquid from the strainer.
Figures 3. and 4. illustrate a second and somewhat similar modification, in which
the wires are round in section, and curved as shewn.
In order to still further add to the stability of the structure, stays 14. or 15. may
be employed. If the stays 14. are used they are permanently hinged at one end to
one of the joints 7, the other end being temporarily fastened to the neighbouring
joint, when the stand is fully extended. Should stays 15. be used instead, they are
permanently hinged at either 7. or 9. and temporarily attached to the corresponding
opposite point; but we find in practice that, for ordinary sizes of strainers the
modifications without stays are sufficient. When the stand is not in use it is folded
up as shewn in Figures 2. and 4. and when it has to be used, it is simply extended
as shewn in Figures 1. 3. or 5. and the strainer placed in position.
Although we have only illustrated and described some modifications of stands
for supporting strainers, yet it is obvious that other modifications may be used
without departing in any essential particular from our invention.
For example-A combination consisting of six wires may be employed in the
construction of the stand, although owing to the restricted space for the basin, we
consider this modification inferior. Again, instead of using wire, we may employ

page_text: either wholly or partially, wood, tubes, channel metal,--as used for umbrellas-or
other suitable material.
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 :-
In stands for supporting strainers:
(1). The design and construction of the combination in a way which gives great.
strength with little weight, as illustrated and described.
(2). The design and construction of the combination in such a way that the
weight of the strainer and its contents adds to the stability of the structure.
(3). The design and construction of the combination as shewn in Figure 5, to
further add to the stability of the structure, that is to say by the use of stays.
(4). The jointing or hinging of the combinations in the manner shewn, in order
that the stand may be instantaneously closed or opened.
(5). The twisting of the wires in the combination as described and illustrated in
Figures 1. and 2.
