page_text: I, JOSEPH TORKER, of Brockway, Minnesota, U.S.A., Inventor, 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:-
This invention relates to horology, and more especially to the indicators used
in connection therewith to designate when it is necessary to wind the timepiece.
To this end the invention consists in the specific construction of alarm devices
adapted for this purpose, all as hereinafter more fully described and as illustrated
in the drawings, wherein―
Figure 1 is a front elevation of the clock mechanism, except the dial, in dotted
lines, with my alarm mechanism shewn in full lines. Fig. 2 is a front elevation
thereof, including the dial, in full lines and shewing the alarm with the indicator
exposed. Fig. 3 is an enlarged perspective detail of the parts of the alarm
mechanism removed.
In the said drawings the latter C designates the clock mechanism, and M the
mainspring, all of the usual construction, and forming no part of the present
invention.
Attached by an eye 1 to some part of the clock-frame is a spring 2, standing
over the mainspring M and having an eye 3 at its other end, into which passes
the hook 4 of a screw-5, carrying a nut 6.
7 is a pin or shaft mounted in the-clock-frame in a suitable manner, and on
this shaft is arranged an arm 8, preferably split at one end-as at 9. and support-
wind up
ing a sign 10, bearing the words
or their equivalents and adapted to-
stand normally in rear of the dial D of the clock mechanism. From said sign the
arm passes in a proper direction to form a bearing 11 on the pin or shaft 7.
Thence it extends, as at 12, alongside the same, and finally it turns outwards,
as at 13, and 14 is an eye, one end of which is mounted on said shaft 7 the other
end of which or the eye proper loosely receives the screw 5 above its nut 6. This
eye is fastened to or forms an integral part of the arm 8 where it turns outward,
as at 13. By this construction it will be seen that the said arm has two bear-
ing points 11 and 14 on the shaft 7, at one side of which it carries a sign 10 and
at the other side of which it stands parallel with said shaft, as at 12, and has its
outwardly extending portion 13, carrying an eye 14.
15 is a spring secured to the clock-frame in any suitable manner and bearing
downward on the portion 12 of the arm S.

page_text: In operation, the clock-mechanism runs as usual, and when it is nearly run
down the mainspring M becomes quite large, as well understood. In this condi-
tion it presses outward on the spring 2, which draws the screw 5 upward. The
nut G raises the eye 14 and turns the arm 13 against the tension of the spring 15,
and the result is the entire arm 8 is swung around shaft 7 as a pivot so that the
sign 10 is caused to descend from behind the dial into position where the words
wind up thereon are readily discernable through the glass front of the clock
casing. The operator is then made aware of the fact that the clock must be
wound or it will soon run down.
All parts of this device are of the desired sizes, shapes, proportions, and mate-
rials, and considerable change in the specific details may be made without depart-
ing from the principle of my invention. It will be clear that the presence of the
nut 6 on the screw 5 permits a certain amount of adjustment of parts, and that
the spring 15, while holding the sign 10 normally hidden by the dial, will permit
the same to be exposed at the proper time. This attachment may be mounted
upon and used in connection with such parts of the clock-frame and its mechanism
already in use as may be found possible.
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:-
(1) In a clock winding alarm, the combination with the clock-mechanism
including the mainspring and dial attached to the clock-frame; of a spring con-
nected at one end with the frame and curving over the mainspring, a screw
attached to the other end of this spring and having a nut thereon, a shaft in the
frame, and an arm pivotally mounted on said shaft and having at one side thereof
a sign normally hidden by the dial, and at the other side thereof an eye loosely
embracing the screw above its nut, as and for the purpose set forth.
(2) In a clock winding alarm, the combination with the clock mechanism
including the main-spring and dial attached to the clock frame; of a spring con-
nected at one end with the frame, and curving over the main-spring, and a rod
attached thereto and having a stop, a shaft in the frame, an arm having a sign
at one end normally hidden by the dial with its body journalled on said shaft
and extending alongside the same and then turned outward, an eye also journalled
on the shaft, and attached to the outwardly bent portion of the arm with its
eye surrounding said rod above its stop, and a spring bearing normally downward
on that portion of the arm which stands parallel with the shaft, as and for the
purpose set forth.
