CHARLES WIENER, OF CIBOLO, TEXAS.
AUTOMATIC HEAT-REGULATOR FOR INCUBATORS.Specification of Letters Patent.
Patented Mar. 29, 1921.
Application filed January 7, 1919. Serial No. 270,035.
To all whom it may concern:
Be it. known that I, CHARLES WIEDNER, a
citizen of the United States, residing at
Cibolo, ' in the -county of Guadalupe and
5 State of Texas, have invented new and use-
ful Improvements in Automatic Heat-Regu-
lators for Incubators, of which the follow-
ing is a specification.
t is the principal aim.and object of the
10 jpreert invention to provide a device of the
above mentioned character designed to be
operably mounted within an incubator and
on the heating lamp therefor and capable of
being adjusted so as to insure of the ex-
15 tinguishing of the lamp when the tempera-
ture within the incubator casing reaches a
predetermined point.
It is an additional'and equally important
object. of this invention to provide a device
20 of the above mentioned character wherein
the thermostat carrying .lever is operably
connected with the wick extinguisher for ex=
tinguishing the flame of the lamp when the
temperature reaches -predetermined point
25 and for subsequently raising the damper of
the lamp casing should the heat within the
casing go above the predetermined point.
More particularly the present invention
contemplates the provision of a device of the
'30 above mentioned character wherein the main
actuating lever is mounted so that it will be
moved -downwairdly by the diaphragm to
consequently cause the successive actuation
of the wick extinguishing carrying lever
35 and the damper carrying lever, an operably
mounted bell crank lever being arranged
between the extinguisher carrying lever and
the diaphragm carrying lever and between
the damper carrying lever - and the dia-
40 phragm carrying lever for insuring of the
proper actuation of the parts at the desired.
time.
It is a more specific object of this inven
Lion to provide a device of the above men-
45 tioned character wherein a spring tensioned
connection is provided between the extin-
guisher carrying' lever and the bell crank
lever for insuring the proper actuation of
the wick extinguisher; to also construct the,
50 wick extinguisher of such size in relation to
the. lamo wick so that the extinguisher will'
leave a small portion near one end of the
wick free to burn= in order that such por-
tion may act as a pilot for' the lighting of
55 the entire wick at the time the temperaturewithin the casing gets colder for the con-
tracting of the diaphragm.
Other improvements and novel details in
the construction and arrangement 'of the va-
rious parts of the apparatus will be brought 60
out more in detail in the description to fol-
low, which for a clear understanding of
the invention should be considered in con-
nection with the accompanying drawings
forming a part hereof, and wherein is dis- 65
closed for the purpose of illustration a con-
venient and satisfactory embodiment of the
invention. It is to be noted in this connec-
tion that minor changes in the construc-
tion and arrangement= of parts may be 70
made without departing from the principle
of operation of the various parts.
The invention is clearly illustrated in the
accompanying drawings, in which:
Figure 1 is a front elevation of the in- 75
vention applied to 'an incubator.
Fig. 2 is a top plan view thereof.
Figo3 is a side elevation of the inven-
tion the casing being shown in section.
Fig. 4"is a perspective detail of the ther- 80
mostatic cracker carrying lever.
Fig. 5 is 'a detail of the extinguisher
carrying lever.
Fig. 6 is a detail of the damper carrying
lever.85
Fig. 7 is a detail of the bell crank lever.
Fig. '8 is a detail view showing the extin-
guisher and its. actuating patts in extended
position.
Fig. 9 is a detail view showing the damper 90
carrying lever raised, and
Fig. 10 is detail sectional view of the up-
per thermostatic crackers and shows the
means b.y which they are suspended from
their attendant bracket. 95
Similar characters of reference 'are em-
ployed in all of: the above described views,
to indicate corresponding parts.
Referring now, more particularly, to the
accompanying drawings there is illustrated 100
a portion of an incubator including a cas-
ing 1 to which is connected a bracket 2 on
one side thereof for supporting a lamp 3
the heat of flames from the wick 4 of which
are communicated to the heat drum 5 sup- 105
ported on the casing above the lamp. In
this connection it is to be understood that
the particular construction of.the lamp and
the drum form 'no essential part of the in-
vention but are merely illustrating the ad- 1101,373,282.
