IMPROVEMENTS IN EGG-TIMERS
Year: 1884

page_text: I CHRISTOPHER WILLIAM CLARK of N° 43 Hertford Road Sparkbrook in the
County of Worcester Foreman of Works do hereby declare the nature of the said
invention for "IMPROVEMENTS IN EGG-TIMERS and in what manner the same is
to be performed to be particularly described and ascertained in and by the
following statement that is to say :-
This Invention has for its object improvements in egg-timers by which any
person is enabled to time the boiling of an egg to say two, three or four minutes or
two and a half three and a half and four and a half minutes or there may be
more than three indicators or less than three indicators and the time to be measured
may be set to any divisions of time desired.
In order that my invention may be more clearly understood and easily carried
into practice I have appended hereunto a sheet of drawings in which
Figure 1 is a side elevation of an egg-timer arranged for three divisions of time:
and
Figure 2 is a sectional plan of the same.
Figure 3 is a sectional plan of an egg timer arranged for four divisions of time
and
Figure 4 is a sectional plan of a similar timer only arranged for two divisions of
time.
Figure 5 is an elevation of one glass, such as would be used for a single egg-
timer.
It will be noticed on reference to Figure 5 that the glass is peculiar being
practically parallel on the upper part A of the neck and also at the lower part B of
the neck thus giving a greater range of travel to the sand and a better opportunity
of computing the time already expired if it is desired to subdivide the time in any
way as is very frequently the case. In the present egg boilers this is not the case
as their conical or taper shape makes the distance travelled one minute different to
that travelled the next minute Of course in a single egg-timer there would only
be one of such glasses used. In Figure 4 two glasses C and D are shown on an
oval stand E of which there would be a duplicate for the top.
Perhaps the most general stand would be the one shown by Figure 1 and 2
which are composed of three glasses F. H. J fixed in the stand K. and K' Now
in this case the glass F may be adapted to empty itself in say two and a half

page_text: minutes the glass H in three and a half minutes and the glass J in four and a
half minutes and either of these glasses may be brought prominently to the front
by turning the stand round upon its base.
The same arrangement may be carried further by Figure 3 where the four
glasses L. M. N and P are set in the base R or there might be a fifth glass added
as per dotted lines S at the centre and the sand might be of a different colour in
the centre or any other glass or glasses for contrast and convenience of reading.
Letters or figures indicating the time of each glass would be either marked on the
stand or on the glasses in any desired style.
It will therefore be evident that considerable variety in design and arrangement
may be carried out without departing from the nature of my invention.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that what I claim is
First The improvements in egg-timers of two or more glasses grouped in one
case or stand and variously timed substantially as herein set forth and
illustrated by Figures 1. 2. 3 and 4.
Second: The improved shaped egg timing glass shown by Figure 5 and as herein
set forth.
