PROVISIONAL SPECIFICATION left by the said Joaquim Antonio de Macedo
at the Office of the Commissioners of Patents on the 14th December 1876.
JOAQUIM ANTONIO DE MACEDO, of Leeds, in the County of York.
IMPROVED EGG BOILER."
"A NEW OR
When the ordinary egg boiler is used (there being no signal given) if it be not
constantly watched during the boiling of eggs the sand is apt to run out before the
cook looks at it; the consequence is that the eggs will be boiled hard.
In my Invention I draw the attention of the attendant by means of the striking
of a bell or other alarum, which is effected in the manner hereafter described.
I employ the "glass" of the ordinary egg boiler. This is placed within a suitable
carriage which is pivoted on a swing frame mounted on suitable standards. Within
the standards, or in any other convenient position, is fixed a bell or other alarum.
To one end of the carriage containing the "egg boiler glass" is attached a hammer
for striking the alarum.
In order to cause the apparatus to which the hammer is attached to operate, the
carriage is upturned simultaneously with the end of the glass containing the sand
or its equivalent, and thrown back to a suitable angle on to the swing frame. The
carriage remains in this position until the sand or its equivalent has run out of the
upper bulb into the lower one; this being done it is immediately overbalanced
and falls over; warning of this is given by the hammer striking the alarum.
The angle at which the carriage is thrown back on to the swing frame is regu-
lated by a set screw, whereby the time occupied before overbalancing is adjusted.
This adjustment is required on account of various kinds of eggs requiring different
lengths of time.

IMPROVED EGG BOILER."
"A NEW OR
When the ordinary egg boiler is used (there being no signal given) if it be not
constantly watched during the boiling of eggs the sand is apt to run out before the
cook looks at it; the consequence is that the eggs will be boiled hard.
According to my Invention 1 draw the attention of the attendant by means of
the strking of a bell or other alarum, which is effected in the manner hereafter
described.
I employ the glass of the ordinary "egg boiler." This is placed within a suitable
carriage, which is pivotted on a swing frame mounted on suitable standards. Within
the standards, or in any other convenient position, is fixed a bell or other alarum.
To one end of the carriage containing the egg boiler glass a hammer is attached
for striking the alarum.
In order to cause the apparatus to which the hammer is attached to operate, the
carriage is upturned simultaneously with the end of the glass containing the sand
or its equivalent, and thrown back to a suitable angle on to the swing frame. The
carriage remains in this position until the sand or its equivalent has run out of the
upper bulb into the lower one; this being dono it is immediately overbalanced and
falls over; warning of this is given by the hammer striking the alarum.
The angle at which the carriage is thrown back on to the swing frame is regu-
lated by a set screw, whereby the time occupied before overbalancing is adjusted.
This adjustment is required on account of various kinds of eggs requiring different
lengths of time.
And in order that my Invention may be more completely understood, reference
is given to the accompanying Drawings and to the letters and marks thereon.
DESCRIPTION OF DRAWINGS.
Figure 1 is a side elevation, and Figure 2 is a front elevation of an egg boiling
machine or apparatus constructed according to my Invention.
a is the sand glass, which may be of a similar construction to that used on the
ordinary egg boilers. This is placed within a suitable carriage b, which is pivotted
at c on a swing frame d. The swing frame d is mounted in bearings e provided
for it on the upper part of the standards. Within the standards for in any other
convenient position is fixed the bell g or other alarum. To one end of the
carriage b containing the egg boiler glass a is attached a hammer h for striking the
bell g or other alarum.
In my Drawings the dotted lines of the egg boiler glass a, carriage b, and
hammer h shew the position of them after being set to work for timing the boiling
of the eggs; the lines shown in full represent the position of the egg boiler glass a,
carriage b, and hammer h after having given the signal by striking the bell g,
notifying thereby that the egg boiling operation is complete.
It will be readily understood that before the operation commences that the sand
or its equivalent must be in the upper bulb, shown in dotted lines, from which it
runs into the lower one until sufficient has passed to allow the apparatus to over-
balance.
In order to regulate the time for boiling I provide on the carriage b a weight i,
which may be adjusted on the screw j by screwing the weight towards the centre
of the egg boiler glass a or from it; the time is thereby lengthened or shortened
to suit the various kinds or sizes of eggs, these requiring different lengths of time
for boiling.
Having now described the nature of my said Invention, and shewn by Drawings

page_text: how the same may be carried into practice, I would have it understood that I do
not limit myself to the exact limits, details, or configuration of the various parts I
have explained and shewn, as the same may of course be varied or modified without
in any way departing from the nature of my said Invention, but what I do claim
and desire to be secured to me by Letters Patent is, the arrangement, construction,
and application of the various parts forming the apparatus for timing the boiling
of eggs, and mere modifications of the same, substantially as herein set forth.
In witness whereof, I, the said Joaquim Antonio de Macedo, have hereunto
set my hand and seal, this Fourth day of June, in the year of our
Lord One thousand eight hundred and seventy-seven.
