Time Apparatus for Extinguishing Gas.
I, PETER BARNIKEL, Shoe Dealer, residing at No. 705, De Kalb Avenue, in the City
of New York, in the Borough of Brooklyn, and State of New York, U.S.A., do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement-
This invention relates to time apparatus for extinguishing gas by which the
flame is automatically extinguished after a given time so as to produce not only
economy in the use of gas but also an effective protection against accidents result-
ing from the blowing out of the flame by persons unaccustomed to the use of gas.
For this reason the attachment is especially adapted for the use of hotels, board-
ing-houses, etc. and also for the sleeping apartments of servants,
in ordinary dwellings as the attachment forms a guard-device against poisoning
by the escape of illuminating gas.
ctc.
The invention consists of a time apparatus for gas which comprises a gas bracket,
a clock train attached thereto, an auxiliary cock in said bracket, a notched dise
operated by the clock train and adapted to be turned so as to wind up the clock
train and mechanism between said notched disc and the auxiliary cock whereby
the clock train produces the closing of the auxiliary cock and the extinguishing
of the flame.
The invention consists further of certain details of construction and combina-
tions of parts which will be fully described hereinafter and finally pointed out
in the claims.
In the accompanying drawings:-
Fig. 1 represents a gas bracket with my improved extinguishing time-apparatus
for gas applied thereto and showing it in its normal position of rest.
Fig. 2 is a plan-view of Fig. 1, and Fig. 3 is a side elevation of the gas bracket
showing the time-apparatus in position while the flame is burning and before the
same is extinguished.
Similar letters of reference indicate corresponding parts.
Referring to the drawings-A represents a gas bracket of any suitable con-
struction which is provided with an ordinary stop cock a and with an auxiliary
stop cock A¹ near the burner B. To the gas bracket is attached in any suitable
manner a small clock train C. In the drawing the gas bracket is provided with
a ledge that is cast integral with its middle or tubular portion to which the clock
train is attached by screws or the clock train may be strapped in any suitable
manner to the tube of the bracket. To the arbor of the main spring is applied a
disc D which is provided at its circumference with a notch d. A crank E is
applied to the square end of the main spring arbor so that the main spring can
be wound up to a certain extent by turning the disc in the direction indicated by
the arrows in Fig. 1. Vertically above the notched disc .D is arranged a ful-
[Price 81

page_text: crumed lever F which is provided with a hook-shaped end f that is adapted to
engage the notch of the disc 1 the opposite end of the lever I being connected
by an intermediate pivot link f with a crank arm f2 that is attached to the outer
end of the auxiliary stop cock A' as shown clearly in Figs. 1 and 3. A strong
helical spring f³ is interposed between the longer end of the fulcrumed lever F
and a perforated stud ft on the casing of the clock train said spring being applied
to a rod f³ that is guided in the perforated stud and pivoted to the lever F.
This extinguishing attachment for gas burners is operated as follows:
When the attachment is in its normal position of rest as shown in Fig. 1 the
auxiliary stop cock A¹ is closed and the fulcrumed lever F rests by the projection
at its end in the notch of the disc. The main cock a is also closed. When it is
desired to light the burner the main cock a is first opened. The notched disc is
then turned by means of its crank handle D¹ in the direction shown by the arrow
in Fig. 1 so that the projection at the end of the lever Frides on the circumference
of the disc and assumes the position shown in Fig. 3. By the intermediate con-
necting mechanism between the lever F and the crank of the auxiliary stop cock
the latter is opened so that the burner can be lighted. As soon as the crank
handle D is released the clock train is operated by its main spring as the same
has been wound up to a certain extent by turning the disc. According as the disc
has been turned more or less the clock train will run for a greater or shorter
length of time until the notch of the disc arrives again below the projection on
the lever so that the latter under tension of its spring f³ re-engages the notch of
the disc and produces thereby the closing of the auxiliary stop cock and the
extinguishing of the flame.
When a light is required only for a short time say only for a few minutes
sufficient to get something from the room the gas is lighted by turning on the
main cock turning the crank of the disc for a partial rotation and then lighting
the flame. As the lever projection will arrive in a few minutes at the normal
position in the notch of the disc and thereby the stop cock be closed automatically
by action of the clock train and the flame, extinguished it is not necessary to
shut off the gas from the cock. When a greater length of time is desired the
notched disc is turned by its crank up to a point near the notch when the flame
will burn say for about ten minutes sufficient to undress and retire as in a hotel,
or servants' room in a private house.
When the clock train has run out that is to say when the projection of the
lever drops into the notch of the disc the auxiliary stop cock is closed and the
flame extinguished. Should a longer time be désired by the person using the
light all that is necessary is to again turn the disc by the crank when the gradual
failing of the light calls attention to the fact that the clock train is nearly run
out. The light may thus be continued for another ten minutes. When it is
desired to extinguish the flame before the clock train has run out the main
cock a is closed and thereby the light directly extinguished.
The whole mechanism may advantageously be enclosed in a suitable casing
having a glass cover opening on that side in which the crank is located. On this
exterior casing is arranged a stop pin g against which the crank abuts so as to
make the projection f of the lever move up close to the notch but prevent it from
dropping into it.
In some cases it may be desirable to interrupt the operation of the attachment
especially when the light is to be used for a greater length of time. In this case
the crank can either be locked to the stop pin by a suitable link or other device or 5
any other mechanism for arresting the return motion with the clock train can
be used.
In this case the attachment cannot work until the locking device is released
again when the clock train will run its course and close the auxiliary stop cock
in the manner described and extinguish the light. Unless so locked however the
attachment will always accomplish its purpose namely the economizing of gas
and the obviating of accidents etc. as aforesaid

page_text: 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:
1. The combination with a gas bracket of an auxiliary stop cock a clock train
supported on said bracket means for winding up the clock train a notched disc
on the main spring arbor of said clock train and mechanism between the notched
disc and the auxiliary stop cock by which the latter is automatically closed and
the light extinguished as soon as the clock train has run out substantially as
set forth.
2. The combination with a gas bracket of an auxiliary stop cock a clock train
supported on said bracket a notched disc on the arbor of the main spring a crank
handle on said disc a fulcrumed and spring-actuated lever provided
with a projection at one end adapted to engage the notch of the disc and
intermediate connection between the lever and the auxiliary stop cock whereby
the latter is opened by winding or partly winding the main spring or automatically
closed by the running down of the clock train substantially as set forth.
