of striking and time movements of clocks
Year: 1886

page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, 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:—
4
This invention, relating to the connection of striking and time movements of
clocks, has for its object to enable the striking movement of a clock to be readily
separated from the time movement without affecting or making the latter
inoperative and to enable the time movement to be removed without affecting
the striking movement and to this end it consists in a clock having a frame
composed of separable sections, the one holding the time movement, and the other
the striking movement.
The invention relating to apparatus for winding clocks and similar mechanism
has as its object to enable two independent main springs or actuators for different
trains of wheel work, such for instance as the striking and going trains of a clock,
to be wound by the movement of a single arbour, actuated by a single key or
equivalent.
Clocks have been made in which a single winding operation is sufficient for
actuating both the going and striking mechanism of the clock, but in such
apparatus the different mechanisms have been primarily actuated from a single
main spring either alone or in connection with a secondary spring which is wound
or strained by the said main spring which in either case has to be sufficiently
strong to perform the entire work of both parts of the clock mechanism.
In the present invention the two trains are actuated wholly independent of one
another by independent springs; and the winding mechanism is adapted to wind
either of the said springs independently of the other, or to wind them both at the
sane operation as may be required.
The winding shaft-wheel may have a key or knob attached to it or may be
squared to receive a socket key in the usual manner, is adapted to turn in both
directions and in its movement in one direction tighten's or winds one of the

page_text: springs, and in the other direction winds the other spring, so that by oscillating the
key back and forth as is commonly practised in connection with stem winding
watches, both springs will be wound substantially simultaneously, but by turning
the said key in one direction only, the corresponding spring alone will be wound.
As herein shown the arbours that are connected with the ends of the main springs
are provided with the usual ratchets which in connection with pawls pivotted on
the frame work, hold the said springs when wound in the usual manner, and the
said arbours are turned to wind the springs by pawls on a pawl carrier on a disc
connected with the key shaft or otherwise adapted to be oscillated back and forth
or turned in either direction, the ratchets of the two springs being at opposite sides
of the said pawl-carrier, and having their teeth turned in opposite directions so
that one is engaged by the pawl-carrier when turning in one direction and the
other is engaged by the pawl-carrier when turning in the other direction.
As shown in this instance the two winding spring arbours in line with one
another and the key shaft connected with the pawl carrier passes through one of
the said arbours which is made tubular for this purpose..

Figure 8 represents an elevation of a clock framework, taken from the same
point of view as Figure 4 but showing a different construction of the framework
and of the winding device.
Figure 9 represents a sectional view of the construction shown in figure 8.
Figure 10 represents a perspective view of one of the mainspring arbours.
Figures 11 and 12 represent sections on line y y Figure 9, looking toward

The same letters of reference indicate the same parts in all the figures.
In the drawing Figures 1 and 4 a², 62, represent the front and back plates which
with the connecting posts c², c², and the smaller intermediate plate d² and the
posts. e, e², connecting the latter to the plate 62, constitute the supporting frame of
the time.movement ƒ³.
The arbours of the time movement train have their bearings in the plates b³, d,
while the plate a³, supports the dial plate g², and the outer end of the winding
post or arbour h.
represent the front and back plates which with the connecting posts k³, k²,
constitute the frame which supports the striking movement 12, and the rear portion
of the winding arbour h. The striking movement 13 may be of any suitable kind
that shown in the present instance being the ordinary French movement, having
a snail wheel 3, which is rotated by a connection with the time movement and
regulates the number of blows given by the hammer at each hourly operation of
the striking movement in a manner well understood.
The entire mechanism of the striking movement is supported by the plates 1,ƒª²
which are permanently connected by the posts 2. The entire mechanism of the
time movement is in like manner supported by the permanently connected plates a²,
b, d, so that each movement will remain in operative condition when removed or
disconnected from the other.
The two frames are detachably connected by posts w², connected to the plate 62
and screws a³, passing through the plate and entering the posts w³. The back

page_text: plate of the striking movement is provided with orifices 63, coinciding with the
screws a³, so that a screw driver can be passed through said orifices for the purpose
of applying or removing said screws, and thus connecting or disconnecting the two
frames. When the frames are disconnected by the removal of said screws, they
may be readily separated without any derangement of the, mechanism of either
frame. That portion of the winding arbour h, which operates the time movement
has no positive connection with the portion which winds the striking movement,
so that the two portions of said arbours can be readily separated, the pawl v
preventing said arbour from unwinding. The centre arbour c³ of the time move-
ment is controlled by the centre arbour d³, of the striking movement which governs
the operation of the latter, by a coupling or joint w³, which enables the two
arbours to be separated, said coupling having 'squared sockets receiving the squared
ends of said arbours.
The chief advantage of making the two movements separable in the manner
described, is that either movement can be taken apart for repairs without dis-
turbing the other movement, so that in case only one movement needs repairing
the labour of taking apart and setting up is materially reduced.
The invention is not limited, however, to the above described construction of
the framework. In figures 8 and 9 the frame is shown without the plate i³, but
similar in other respects to that above described; the arbours of the striking
movement being journalled in the plates 8, 62. In this case, as the plate b'
supports the arbours of both movements neither movement can be separated from
the other intact; but the striking movement can be separated from the time
movement without disturbing the latter, and the time movement can be removed
without disturbing the striking movement.
The construction last described, therefore, has practically all the advantages of
the first described construction and is more compact.
Referring inoro particularly to Figures 4, 5, 6 and 7 the main spring a (see
figure 5) enclosed in and having one end connected with a drum b, and the driving
gear c, connected with said druin and actuating a train of wheel work not shown,
which may terminate in an escapement and actuate the hands of a clock, may all
be of any usual construction as they constitute no part of the present invention.
The spring a drum b' and gear c¹ forming a portion of a separate train, may
also be of usual construction, and the said train employed to actuate the strikes of
the clock in the usual manner.
The inner end of main spring a, is connected with a winding arbour d, which
turns loosely within the gear c, and drum b, for the purpose of drawing up or
winding the spring while the other end is pressing against the drum to actuate the
train of wheel work, and the said arbour d, is provided with a ratchet e, which is
engaged by a retaining pawl f, on the frame work, which thus holds the inner end
of the spring a, when wound up by rotating the arbour d in the usual manner.
The spring a is also connected with an arbour & provided with a ratchet e¹
engaged by a retaining pawl f¹ on the frame work operating to wind and hold the
spring a¹ in the usual manner.
Clocks having two independent main springs and trains as thus far described
have usually had the arbours d and a squared to receive a key which is to be
applied first to one and then to the other to wind the corresponding main springs,
or actuators the said arbours usually being placed at opposite sides of the frame
work of the clock.
As shown in this instance the said arbours are placed in line with one another
and the teeth of the ratchets e, e¹ are inclined in opposite directions so that one
of the said ratchets is permitted by the corresponding pawl to turn in one direction
in winding the corresponding spring, while the other can turn only in the opposite
direction as indicated by the arrow thereon in Figure 4.
The ratchets e, e¹ have between them a pawl carrier g, shown as a disc attached
to a key shaft h which extends through the arbour d, of the spring a, the said

page_text: arbour being made tubular for this purpose and the said smart being free to turn
therein,
The pawl carrier g, on the side adjacent to the ratchet e, is provided with a
winding pawl i, adapted to engage the teeth of the ratchet e when the pawl
carrier is turned in one direction but slipping freely over the said teeth when
turning in the other direction, and the said pawl carrier is provided at its other
side with another winding pawl i' which engages the teeth of the ratchet e¹ when
'the said carrier is turning in the direction to permit the pawli to turn over the
teeth of the ratchet e. The relation of the pawls i, ¹ are best shown in Figure 6
in which they are seen looking from the side occupied by the ratchet el which is
'not shown in the said figure, the ratchet e being shown in dotted lines.
"
The operation is as follows: The arbour h is engaged by a key K, or provided
with a suitable knob or handle by which it may be turned back and forth by the
operator without letting go the said key or knob, and in its movement in one
direction it will cause the pawl i to engage and rotate the ratchet e, winding the
spring a which is then held by the pawl f, while the pawl-carrier is being turned
back in the other direction, during which movement it will cause the pawl i¹ to
engage the ratchet e¹ and wind the spring a¹ which is then held by the pawl f'.
As a person in winding a clock cannot turn his hand continuously but has to
turn it back after each, fraction of a rotation it will be seen that by the present
invention this backward movement is utilized and both springs can consequently
be wound as quickly as either one alone, thus saving half the time of winding the
clock, but if only one of the springs has been permitted to run down, or if by any
reason it is desired to wind only one this can be done by turning the key in the
proper direction in the usual manner.
It is not essential to the invention that the two springs with their arbours be
placed in line with one another as shown, since an intermediate pawl carrier, may
be arranged in connection with two springs when placed side by side as in clocks
of ordinary construction, and it is also not necessary that the pawl carrier be
operated by a key, as it may be oscillated back and forth by means of a projecting
arm or equivalent.
For convenience in construction the ratchets e e¹ are not made integral with the
arbours d, d¹ but have a squared socket for engaging them as shown in figures 5
and 7 and the other end of the arbour d may be squared as shown to facilitate the
letting down of the spring when required. It is obvious that weights 'might be
wound by similar mechanisin which would be within the scope of the present
invention.
In Figures 8, 9, 10,.11, and. 12 certain modifications are shown, adapting the
winding mechanism to the modified construction of the framework shown in
Figures 8 and 9 and previously described; said modifications being as follows:
The arbour h, to which the pawl carrier g, is attached is extended through the
pawl carrier and turns loosely in two hollow arbours d d', which are secured
respectively to the springs a a', and turn loosely within the gears c c¹. Said
arbours, one of which is shown in perspective in tigure 10, have squared ends fitted
in square sockets in the ratchets e¹, the hollow arbours being thus positively
engaged with said ratchets. The winding pawls ii, are pivotted to the pawl
carrier as before.
The retaining pawls ffl, are pivotted to opposite sides of the middle plate b² of
the frame; said plate having an aperture in which the pawl carrier stands, the
sides of the pawl carrier being about flush with the sides of the plate b².
Each of the winding pawls i ¹, has a tooth or shoulder ³, which is capable of
being engaged by the end of a spring j³ secured to the pawl carrier; the engage-
ment of said spring and tooth holding the pawl out of engagement with its ratchet,
as shown in Figure 12. This device is provided to enable either of the winding
pawls to be made inoperative or held away from its ratchet when it is desired to
let down either of the springs:**
