PROVISIONAL SPECIFICATION.
An Improved Thermometer for Use in Baking and for like
purposes.
I, JOHN GÖBEL, of 20, Maxted Road, Peckham, Baker, do hereby declare the
nature of this invention to be as follows:-
The object of my invention is to provide a thermometer for the use of bakers or
the like so arranged as to indicate to those using it the corresponding requisite
temperature of the water or liquid required for mixing the dough according to the
temperature of the room or chamber in which the mixing of the dough is carried
on-it being understood that the temperature of the water used should be below
the normal when the temperature of the mixing chamber is above the normal and
vice-versa.
In carrying out my invention I centrally pivot on a thermometer at any con-
venient point a toothed wheel so arranged as to gear into sliding racks on either
side of the thermometer so that on one of these ascending by the turning of the
wheel the opposite one will descend and vice-versa.
-
The thermometer is graduated and marked in figures on each side of the tube
and the sliding racks are provided with pointers to indicate the proper temperature.
The toothed central wheel is provided with a thumbscrew or milled head for
convenience in turning the same.
In using the instrument the racks are set so that their pointers both indicate the
temperature say 72° at which the heat of the apartment in which the dough is
mixed and that of the water used coincide; should the heat of the apartinent rise
to say 80° the wheel is turned until the pointer attached to one rack, say the right
hand, coincides with the mark on the thermometer indicating 80°, the pointer on
the opposite rack will now point to 64° and this shews the temperature at which
the water for mixing should be used, or if the heat of the apartment falls to
say 64° the requisite heat of the water is shewn by the upper pointer to be 80°..

COMPLETE SPECIFICATION.
An Improved Thermometer for Use in Baking and for like
purposes.
I, JOHN GÖBEL, of 20, Maxted Road, Peckham, Baker, 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 object of my invention is to provide a thermometer for the use of bakers or
the like, so arranged, as to indicate to those using it, the corresponding requisite
temperature of the water or liquid required for mixing the dough, according to the
temperature of the room or chamber in which the mixing is carried on-it being
understood that the temperature of the water used should be below the normal,
when the temperature of the chamber is above the normal, and vice-versa.
Referring to the accompanying drawings and to the figures and letters of
reference marked thereon,
Figure 1 represents a front elevation of my improved thermometer and
Figure 2 a part vertical central section of the same drawn to a larger scale.

page_text: In carrying out my invention I pivot at any convenient point on the scale plate A
of the thermometer, below the graduations thereon, a toothed wheel B. This
toothed wheel B, engages with two sliding racks C. D, retained at the sides of the
thermometer case by housings E. For any other suitable device, so that on the
wheel B being turned by means of the milled head or thumb screw G, one rack will
descend and the other ascend, and vice-versa.
These two racks C D are provided with pointers H. J, and the scale plate A is
marked with graduations as usual.
The wheel B and milled head G are mounted on a shaft or stud L, supported by
a bridge piece M, (Figure 2) and fitting over a short stud or pin N. This shaft L
is surrounded by a coiled spring or similar device P, so that the wheel B when
lifted up and disengaged from the racks for the purpose of adjusting them, as
hereinafter described, may be returned to its normal position by such spring P.
To use the instrument the wheel B is turned until the pointer H on the rack C
indicates the temperature of the room or apartment. The liquor for preparing the
dough should now be made up according to the temperature at which it is generally
used. The thermometer is then inserted in the liquid for a short time, the wheel B
is lifted up, and the rack D moved by pencil or finger until the pointer J indicates
the temperature at which the mercury then stands, the wheel B is then dropped
into its place, and in all future use, the wheel B is simply turned until the pointer H
indicates the temperature of the room or apartment, and the pointer J will then
show the temperature to which the liquor must be made for mixing or preparing
the dough or paste.
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 :--
In, or on, a thermometer for the use of bakers, or for similar purposes, the
employment of a toothed wheel pivotted thereon, and adapted to gear with sliding
racks fitted with pointers, as and for the purposes hereinbefore described, and sub-
stantially as illustrated by the accompanying drawings.
