page_text: I, EDWARD HEUER of Bienne Switzerland, Watch Maker, do hereby declare the
nature of my said invention and in what manner the same is to bo performed, to
be particularly described and ascertained in and by the following statement :-
The object of my invention is to manufacture a new and improved description of
watch, having striking and repeating mechanism, driven by a separate train of wheels
and a separate main spring; the ordinary going main spring and the striking main
spring being both wound up by the ordinary winding mechanism.
An important feature in my invention being that the watches may be manufactured
and sold as cheaply as ordinary repeater watches.
And in order that my said invention may be particularly described and ascertained
reference is hereby made to the accompanying drawings in which similar letters of
reference indicate corresponding parts.
Fig. 1 is a plan view of iny invention drawn to an enlarged scale.

Fig. 2 is a separate enlarged view of the ordinary quarter snail d and locking
snail o.
Fig. 3 is an enlarged side view of the lever a and the starting mechanism.
Fig. 4 is a plan view of the reverse side of the watch showing the winding
mechanism.
Fig. 5 is a section of the toothed ring 2 with its shifting boss 3.
bis the cannon pinion upon which the ordinary and well known quarter snail d and
locking snail o work.
•
The wheel c is driven by a wheel of the same diameter upon the cannon pinion
and revolves at the same speed as the cannon pinion. This wheel c drives the pinion e
(shown by dotted lines) at the rate of four revolutions per hour. The pinion e carries
a leaf e'. An inclined plane is formed on the underside of the leaf e¹.
a is a lever, pivotted at a² and fitted with a spring a, which raises its longest end,
as shown in Fig. 3. The lever a has inclined planes formed upon it at a and a³.
The end a is forked, the fork entering the groove between the finger wheel and the
rack pinion g. h is the rack, which is pressed in one direction by the spring h¹
preparatory. to striking.

page_text: 7 is a spring which actuates the quarter rack m in one direction, when set free by
the lifting of the finger wheel by the lever a. The tail m' of the quarter rack m
then falls on the quarter snail d carried by the cannon pinion b.
i is a lever, pivotted at ¹; the end being pressed upwards by the spring k; the
other end resting upon a pin a' attached to the lever a, and being raised thereby.
when the lever a rises. The end of the lever i, engages with the anchor wheel n to
which it acts as a skid or brake, stopping its rotation while the striking mechanisms
(consisting of the quarter rack m, the rack h, the finger wheel, the rack pinion g
and the striking rack p) return to their respective snails. 9 is the ordinary star wheel
to which the hour snail is fitted.
s and are the tails of the striking hammers which are operated in the usual
manner, s¹ being worked also by the striking rack p..
The striking mechanism works simultaneously with the ordinary works striking the
hours and the first, second, and third quarters past the hours. The striking can
however be stopped at any time by pressing the button a whereby the end of the
lever w stops the movement of the tail 2 of the rack h. The button may be fitted
with a slide for retaining it in the required position.
v
When the watch is required to repeat the button is pressed inwards, whereby the
lever is caused to depress the end of the lever a; the underside of the lever being
formed as an inclined plane, which acts upon the inclined plane a² of the lever a.
This operation raises the finger wheel f, thus releasing the quarter rack m and
disengaging the cylinder ratchets (Fig. 3) whereby the striking mechanism is
allowed to return to the snails, and the repeating is effected.
In ordinary use, the leaf e¹ of the pinion e operates upon the lever a in a similar
manner, every quarter of an hour, by means of its contact with the inclined plane a¹
of the lever a.
When setting the hands, the striking mechanism is kept at rest by the pressure of
the lever u by means of the button u³, which temporarily locks the striking inechanism
by the lever and disengages the keyless mechanism from the winding gear; the end
of the lever u holding down the lever a at a² and the end of the lever we stopping
the tail of the rack h. The bar a is thus held down to avoid contact between the
leaf el and the bar a, while turning the hands backwards.
y is the well known mechanism for keyless winding and setting of the hands by
means of the pendant 3, the mechanism is old but its application to repeater watches
is now.
The winding is both right and left-handed, one mainspring being wound up by the
right hand movement, and the other by the left hand movement, as shown in Fig. 4,
in which 7 is attached to the going spring and 8 to the striking spring. 1 is a bevel
wheel operated in the usual manner by means of the pendant . This bevel wheel 1
gears into the toothed ring 2 which rotates on the shifting boss 3. The ring 2 has
bevel teeth and ordinary teeth, as shown in Section in Fig. 5. The ring 2 is loose
upon the shifting central boss 3. 4 and 5 are two studs fixed in the plate, and
passing through the central boss 3 as shown. The stud 4 acts as a fixed centre to the
boss 3, while the slot 6 in the boss 3 allows the ring 2 to gear with either of the
wheels 7 or 8 according to the direction in which the bevel wheel 1 is turned.
It will be obvious that on turning the pendant in one direction the spring 7 may
be wound up, and in the other direction the spring 8 may be wound up.
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 1
claim is :-
:―
1. The manufacturo and use of combined repeating watches and clock watches,
*substantially as hereinbefore described and illustrated by the drawings.
2. In a combined repeater and clock watch the application and use of keyless
mechanism subscribed as described.
3. In repeater watches and clock watches, the application and use of the bevel and
spur ring 2 working loose upon the shifting boss 3 having a fixed centre at 4 and a

page_text: slot at 6, working on the stud 5, and capable of gearing into the wheels 7 or 8 by
turning the bevel pinion 1 to the right or left for the purpose of winding up,
substantially as hereinbefore described and illustrated by Figs. 4 and 5 of the
drawings.
4. In a combined repeater and clock-watch the application and use of an independent
train of wheels driven by an independent spring motor for operating the striking
mechanism substantially as hereinbefore described.
5. In a combined repeater and clock watch the application and use of the lever a
operated primarily by the leaf attached to the pinion e for ordinary striking; also
by the lever for the purpose of repeating; and also by the lever u when setting the
hands, substantially as hereinbefore described and illustrated by the drawings.
6. The general construction combination and arrangement of the several and
respective parts together constituting my invention of improvements in the construction
of repeater watches and clock-watches substantially as hereinbefore described and
illustrated by the drawings.
