Improvements in Means for Winding Up Regulator Clocks.
A communication to me from ERNST LUEDDECKENS, of Liegnitz, in the Empire
of Germany, Doctor.
I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex, 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 and accompanying drawings, that is to say :-
This invention relates to improved means for winding up regulator clocks from
the lower end of the clock, casing, thereby preventing the necessity for standing
upon a chair, bench, or table, in order to reach the dial into which the key for
winding up the weight had to be introduced. The improved means for winding up
the clock further obviates the necessity for opening the door of the casing in order
to wind up the clock, and in consequence the casing is not liable to become shifted
out of its true perpendicular position, nor can any dust enter through the door
while the clock is being wound up.
The door of the casing may indeed be permanently and hermetically closed,
after the speed of the clock has been exactly regulated. The key-hole or holes in
the dial which in some degree, disfigure the dial, are entirely dispensed with.
In the accompanying drawings which are in illustration of the invention, one
modification of the invention which has been found to be of practical service, is
illustrated, Figure 1 being a front view of a regulator clock, comprising the
improved means for winding the clock up which forms the subject of the invention.
Figure 2 is a vertical, longitudinal section of Figure 1. Figure 3 is a vertical
section at right angles to Figure 2, Figures 4 and 5 represent upon an enlarged
scale, the upper part of the mechanism for winding the clock up; Figure 4 being a
front elevation and Figure 5 a side elevation of the same.
The shaft 6 of the drum a on which the cord or chain of the weight is wound,
does not, as usual, extend with a square portion through a hole of the dial A, to be
wound up by a key, but the said shaft extends rearward and has a square end
which enters into a correspondingly shaped hollow pin or lug c centrally mounted
upon the chain wheel d Figure 5. The said chain wheel d freely turns within a
bridge or bracket e upon the rear plate B. Within the lower part of the casing,
preferably within the bottom piece C is lodged another chain wheel d¹ similar to
the upper chain wheel d. This lower chain wheel, turning in a recess in the bottom
piece C has its shaft projecting into an aperture to receive the key g and the said
aperture may be preferably covered by a shield h, Figure 1. An endless chain or
cord i passes round the two wheels d, d', the said chain being arranged behind the
pendulum F and bob D, closely adjacent to the rear side E of the casing, or it may
be lodged within a recess of the said rear side E. When the wheel d¹ is turned by
the key, the chain i will transmit motion to the other wheel d and through the pin c
to the shaft b of the drum a. In order to prevent the pendulum from being
stopped or hindered in its oscillations by the shaft 6 and pin or stud c, the pendulum
rod F is preferably formed with an annular portion F¹ surrounding the said shaft b
and stud c, as clearly shown in Figures 4 and 5.
The key g may conveniently be preserved or laid aside when out of use, in a
recess of the ornamental piece G, detachably secured to the base piece C of the
casing, and provided with a sliding or other door k to cover the recess.
The winding up of the clock is performed as follows:-
Remove the ornamental piece G, open the door k, withdraw the key g from the
recess therein, put the key into the key-hole, after removing the shield, turn the

page_text: key and consequently the wheel d', which transmits motion to the corresponding
wheel d, the latter turning by its hollow stud or pin c, the shaft 6 of the drum A.
By this means the weight suspended from the said drum a is wound up. When the
weight is up, the key g is withdrawn, the shield pushed to close the key-hole and the
key placed again into the recess of the piece G as shewn in Figure 2, the said
piece G is then fitted again in its place as shewn in Figures 1 and 3. The said
piece G may be secured against falling down by springs arranged at the sides of
the pin 1, or by any other suitable means.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The improved means for winding up, regulator clocks from the lower end of the
casing, consisting of the combination, with a wheel d¹ lodged in the base piece C of
the caring, of a second wheel d in the upper part of the casing, a chain, cord, or
other driving mechanism for transmitting motion from the lower wheel to the
upper wheel, and means for coupling or gearing the upper wheel & with the drum a,
for winding the weight up, substantially as and for the purpose set forth.
Dated this 10th day of August 1892.
