having Reference to Pyrometers Used for Baking Purposes.
I, WILLIAM FREDERICK MASON, of Longsight, Manchester, Engineer, do hereby
declare the nature of this invention to be as follows :-
The improvements consist in the arrangement of a dial with means for indicating
both heat and time in combination, whether such dial be fitted with clockwork or
other moving power or is only provided with "hands" or pointers capable of manual
adjustment; and have for object the better regulation of the baking of bread or other
substances in bakehouses.
To accomplish this and to effect my improvements, I form a dial having two con-
centric circles of figures and divisions thereon, one of these-by preference the
outer is divided into the twelve or twenty four hours of the day and each hour into
any convenient number of parts,-by preference six divisions, forming ten minutes
each, and the other, preferably the inner, is divided into any convenient number of
degrees of heat of the ordinary Pyrometer scale.
From the centre of the dial radiate the "hands" or pointers, which may be two or
three as desired. One, or two, of these will reach to and point to the time circle, and
the other to the heat circle; and, by manual adjustment, will form for the baker an
indicator of the heat at which the oven is, together with the time, when a batch of
bread or other substances is entered for baking, instead of trusting to memory, or
writing, as is usually the case.
To render the apparatus more efficient still, the time "hands" may be actuated by
a suitable clock, and may be provided with an alarum, gong, or electric bell attach-
ment, for giving alarm when the batch has been in the oven the prescribed length of
time, and the apparatus may be also fitted up or mounted either as a separate
instrument, or in conjunction with the Pyrometer itself if desired, and other variations
of details may be made. without departing from the peculiar character of the
invention.

I, WILLIAM FREDERICK MASON, of Longsight, Manchester, Engineer, 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 :-
"
The improvements consist in the arrangement of a dial with means for indicating:
both heat and time in combination, whether such dial be fitted with clockwork or
other moving power, or is only provided with "hands or pointers capable of manual
adjustment; and have for object the better regulation of the baking of bread or other
substances in bakehouses.
To accomplish this and to effect my improvements, I form a dial having two con-
centric circles of figures and divisions thereon, one of these by preference the
outer is divided into the twelve or twenty four hours of the day and each hour into
any number of convenient parts,-by preference six divisions, forming ten minutes
each and the other, preferably the inner, is divided into any convenient number of
degrees of heat of the ordinary pyrometer scale.
From the centre of the dial radiate the "hands" or pointers, which may be two or
three as desired. One, or two, of these will reach to and point to the time circle, and
the other to the heat circle, and, by manual adjustment, will form for the baker an
indicator of the heat at which the oven is, together with the time, when a batch of
bread or other substances is entered for baking, instead of trusting to memory, or
writing, as is usually the case.
To render the apparatus more effective still, the time "hand" or "hands" may be
actuated by a suitable clock, and may be provided with an alarum, gong, or electric
bell attachment, for giving alarm when the batch has been in the oven the prescribed
length of time, and the apparatus may be also fitted up or mounted either as a separate
instrument, or in conjunction with the pyrometer itself if desired.
The simplest form of my improvements is a dial as already described having two
"hands
or pointers only, such "hands" or pointers turn upon the centre pivot with
sufficient friction to enable them to be set by hand at any point desired. With this
form of dial, time or pyrometric comparisons, or both, may be made with separate
and ordinary clocks or time-keepers or pyrometers, or both.
The dial may however be fitted with a third "hand or pointer which may be
actuated by clockwork attached or connected with the instrument, so that the time
comparisons may be made upon one and the same dial. In like manner, any form of
pyrometric indicator may be attached or connected with such dial, as will be readily
understood. A further combination of apparatus is obtained by placing in connection
with the "hands" or other portions of such dial an electrical circuit for the purpose
of ringing a bell, or striking a gong, at any moment at which such dial or portion

page_text: thereof may be adjusted to make electrical contact, as is also already well
understood.
This electrical apparatus may be constructed in one piece of mechanism with the
dial, or, by means of wire connections, the circuit may be extended, so that the bell
or gong may be rung at any distance required. Or the clockwork arrangement may
be provided with an ordinary alarum mechanism for the same purpose. And other
variations of details may be made without departing from the peculiar character of
the invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
دو
The employment of a dial with means for indicating both heat and time in com-
bination, whether such dial be fitted with clockwork, electrical or other moving power,
or is only provided with "hands or pointers capable of manual adjustment, for the
purpose of regulating the baking of bread or other substances in bakehouses,
substantially as hereinbefore described.
