Improved Means for Winding a Spring or Weight for Actuating
Clockwork or like Mechanism.
1. IGNAZ SCHEINBERGER, of Nagy-Kikinda, in the Kingdom of Hungary, Bank
Manager, 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 apparatus for automatically winding up the spring or
weights in clocks, regulators and similar devices; the opening and shutting of a
room-door being utilized for rotating the arbor. The apparatus, when the mechanism
is completely wound up, is automatically thrown out of gear.
In the accompanying drawings, Fig. I is a front view of clockwork to which the
present invention has been applied; the winding apparatus being in gear. Fig. 2 is
à similar view; the winding apparatus being out of gear. Fig. 3 is a horizontal
section on the linea (Fig. 2). Fig. 4 is a side view of the door-actuated vibrating
device; Fig. 5 being a front view, on a smaller scale, shewing the relative positions
of the vibrating device and the door. Figs. 6ª and 6b are a front and a side view of
the pawl.
In carrying out this invention, I prefer to arrange the apparatus in the following
manner-Over the door, the opening and shutting of which is to be used for
winding up the spring or weight, a bent vibrating lever a is fixed to a pivoted
shaft a*.
Mounted in a bracket on the door is a roller t, which is in contact with
the under side of the bent lever a, so as to raise the lever on the opening or shutting
of the door. The shaft a is furnished with a second arm or lever b, which, by
means of cords 's carried over rollers u, transmits the vibrating motion of the
arm a to a rocking detent-wheel c. The cord is united to the cord s¹ by a screw-
couplings, which serves to regulate the length of the united cords. The detent-
wheel is mounted on, and can move to and fro about, the outer end of the arbor o ;
a ratchet-wheel h, firmly secured to the arbor, being placed behind the detent-
wheel c.
To the detent-wheel c is pivoted a detent or pawl, which gears with the
ratchet-wheel; the latter being turned by the pawl when a pull is exercised on
the cords. The pawl is furnished with a limb e, the position of which is so
affected by a lever d, also pivoted to the wheel c, that, when the lever strikes against
the stop, the pawl is placed out of gear with the ratchet-wheel h. The cords is
attached to the wheel cat cl, to which point is also attached a cord p'; the latter
passing over a pulley and being fastened to the free end of a lever. The lever
is pivoted at , and is loaded with a weight p. A weight q, furnished with a roller
for a connecting cord, is also provided for throwing the winding apparatus out of
gear. The connecting cord r¹ is coiled up whilst the clockwork or other mechanism
is being wound, and uncoiled as the clockwork or other mechanism runs down.
lever is formed with a projection m, against which the roller strikes when the
weight is raised sufficiently. The arbor o, instead of being actuated by a spring,
may be actuated by the weight q.
The
The action of the parts is as follows:- -Whilst the door is being opened, the
rollert, by pressing against the inclined surface a' (Fig. 4) of the lever a, causes the
shaft a to partially rotate and lift the arm b, thus moving the detent-wheel c, through
the instrumentality of the cords s¹, in the direction indicated by the arrow II
(Fig. 1). By means of the detent and the ratchet-wheel , the arbor o is at the
same time turned and the tension on the spring increased or the weight raised to a
corresponding degree. During the opening of the door, the roller t leaves the
surface a¹ and permits the lever a to fall into its normal position. Whilst the door is
being closed, the roller t, by pressing against the surface a of the lever a, again
causes the shaft a* to partially rotate. The tension on the cords p¹ s¹ b' is produced

page_text: by the weight p, under the influence of which the wheel c returns (after each
opening or closing movement of the door) in the direction of the arrow I (Fig. 2)
to its original position, ready to again act through the ratchet-wheel on the arbor o.
When the weight q is raised sufficiently, the roller presses against the projection m
and raises the lever ; the tension due to the weight p being thus transferred from
the cords p, s¹ and through the lever to the cord. Thereupon the weight p
cannot act to pull the wheel c from the position shewn in Fig. 2 to that shewn in
Fig. 1.
As previously explained, the lever d, when in contact with the stop n, acts
on the arm e, and holds the detent or pawl out of engagement with the ratchet-
wheel h.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I claim :—
1. The improved means arranged or operating substantially as herein described
for winding a spring or weight for actuating clockwork or like mechanism.
2. The improved apparatus for winding a spring or weight for actuating clockwork
or like mechanism constructed or arranged substantially as herein described and
comprising a lever moving to and fro upon the opening and shutting of a room-
door, and means, such as the cord b', coupling s, cord s' and weight p, for communi-
cating the movement of the lever to a rocking detent-wheel, whereby, through a
pawl and ratchet-wheel or equivalent means the arbor is rotated; means being also
provided for automatically throwing the apparatus out of gear to prevent over-
winding.
3. In apparatus of the kind referred to in the preceding claiming clauses, the
employment of a lever pivoted to a detent-wheel and acting on an arm connected to
a pawl substantially' as described and for the purpose of automatically disengaging
the pawl from the ratchet-wheel.
4. In apparatus of the kind referred to in the first and second claiming clauses, the
employment of a pivoted lever connected to a detent-wheel through a cord sub-
stantially as described; the lever, when suitably supported, serving to remove the
tension from the cord pl and thereby causing the winding apparatus to be thrown out
of gear.
