IMPROVEMENTS IN WATCH MOVEMENTS
Year: 1885

page_text: I REUBEN SQUIRE, of 37 Myddelton Square in the County of Middlesex Watch
Manufacturer do hereby declare the nature of my invention for IMPROVEMENTS IN
WATCH MOVEMENTS to be as follows:-
A provision for (1) the adjustment of the curb pins (2) the recoil of the barrel
arbor of going barrels (3) a substitute for the bolt (4) protection to the balance
pivots and holes (5) a larger barrel and an auxilliary winding for sunk balance
movements.
The curb pins may be made adjustable by fitting each curb friction tight to a
slot made in the arm of the index in the direction of its length and along which
slot the curbs may be moved nearer to or further from the centre of the balance.
A larger recoil than usual of the barrel arbor of going barrels may be obtained
by forming the click at the end of a spring the spring being circular shape
preferably and attachable outside and around the periphery of the ratchet so that
when the ratchet draws the spring into a circular shape the ratchet in so doing
may recoil more than usual
The substitute for the bolt is designed to enable the movement to be opened
when the movement is jointed to the case and when a bolt is not desired. A pro-
jection from the edge of the plate has a notch made in it like the ordinary bolt,
which permits the thumb or finger nail to open or close the movement. A spring
may be attached to the plate or to the case .to keep the movement in place.
To prevent the case being pressed upon the balance cock supports may be placed
between the plate and case and be attachable to either-the dust cups at the wind
square or set hands especially in sunk balance movements may also be made to
serve as supports to the case.
.
A larger barrel than usual and a left-winding mechanisin consisting of an
auxilliary wheel and axis may forin a special feature of the movement already
described as the sunk balance movement in which the balance is sunk in the plate
outside the centre hole-and the teeth of the ratchet and auxilliary wheels may
be formed ratchet or saw-tooth shape instead of ordinary-tooth shape when
desired.

page_text: I REUBEN SQUIRE of 37 Myddelton Square in the County of Middlesex Watch
Manufacturer do hereby declare the nature of my invention for IMPROVEMENTS
IN WATCH MOVEMENTS and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
A provision for (1) the adjustment of the curb pins of the regulator (2) the
recoil of the barrel arbor of going barrels (3) a substitute for the bolt (4) protection
to the balance pivots and holes (5) a larger barrel and an auxilliary winder for
sunk balance movements.
The curb pins may be adjustable by being movable on the arm of the regulator
'preferably by being fitted friction tight to a slot made in the short end of the
regulator in the direction of its length and along which slot the curbs may be
moved nearer to or further from the centre of the balance.
A larger recoil than usual of the barrel arbor of going barrels may, be obtained
by forming the click at the end of a circular spring which is placed around the
periphery of the ratchet slightly excentric to the ratchet so that when the ratchet
draws the spring into a circular shape a larger recoil than usual may be given to
the arbor.
The substitute for the bolt may be preferably a piece of square or round wire
attached to the edge of the pillar plate with a notch at the end to receive the
finger nail:
:
To prevent the case being pressed upon the balance cock, supports may be placed
between the case and the plate and be attachable to either. These supports may be
hollow or solid cylinders or blocks or other supports of any suitable form to give
rigidity to the case and in keywatches may be utilised as dust cups. In the latter
case each cylinder is preferably fitted to a hole made in the bar over the barrel one
end resting on the plate under the bar. The cylinder may be attached to the case
if desired and project above the dome as much as the outer bottom is above the
dome thus also supporting the outer bottom and preventing the passage of dust
through the keyholes. This latter arrangement may consist of either one or two
cylinders for each wind hole.
A larger barrel than usual and an auxilliary winding mechanism consisting of a
wheel gearing with the ratchet and mounted upon a shaft having the winding
square at the other end may form a special feature of that kind of fullplate
movement in which the whole diameter of the balance is outside the centre of. the
top plate. The teeth of the wheels may be saw or ratchet shape if desired.
DESCRIPTION
ON OF DRAWINGS..
..
Figure 1, shews the curbs (a) (b) mounted on the short arm (c) of the index in
which is made a slot, to the sides of which slot the curbs are fitted friction tight.
The curb (b) has a crook end at right angles to the perpendicular which covers the
end of the curb (a) and keeps the hairspring from passing out. The curb (b) is
slided towards the end of the arm to allow the spring to pass out. Fig. 2 is the
curb in section.

page_text: Fig. 3 shews the top plate B of that kind of full plate movement in which the
whole diameter of the balance is outside the centre of the plate as at A.
The name bar (a) over the barrel is large enough to embrace the dust cups (t) at
the centre and at the wind hole. These cups are preferably hollow cylinders with
a flange at one end as shewn at figure 5 and in section at (t) figure 4. Each cup
is preferably fitted to a hole in the name bar (a) at (t) figures 3 & 4 and is long
enough to reach the case (n) fig. 4 and being larger in diameter than the key
hole (x) fig. 4 receives the dust that may pass through the key hole and also
prevents the case from being pressed in. In fig. 8 the cylinder (c) is fitted to the
wind hole of the case or the set hands hole and supports the outer bottom (b) as
well as preventing the passage of dust through. In this figure, (n) is the inner
bottom, (a) the name bar and (t) the cylinder attached to the name bar.
The solid cylinders (e) figures 3 & 4 are shewn attached to the top plate B and
may be placed as shewn in fig. 3 or in any other suitable place.
The barrel is larger than usual as shewn at (d) figure 3.
The substitute for the bolt is shewn at (a) figure 6. This piece (a) is a fixture
to the plate A and may be made of any metal and of any other form if desired.
The auxilliary winder is the wheel (b) figure 7, which is attached to the end of
a shaft and gears into the ratchet (a). This is the ordinary winder but it is now
in its adaptation to the movement shewn at figure 3.
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
A watch having any one or all of the following characteristics―
1st An index in which either or both curbs are movable so as to be adjustable
to the size of the hairspring.
2nd A shaping of the plate or any attachment to it in lieu of the ordinary bolt
by which the movement when jointed to the case may be controlled in opening or
shutting it.
3rd One or more supports of any kind, preferably as hollow or solid cylinders,
attachable to the movement or to the case to prevent the movement or the case
from being injured by external pressure and to prevent dust from passing into the
movement, as shewn in figures 4 & 8 particularly in the kind of fullplate movement
in which the balance is situated outside the centre as in figure 3 for example.
4th A larger barrel than usual especially in the movement described in
paragraph 3.
5th An auxilliary winder when applied to the movement described in paragraph 3.
6th A name bar large enough to allow the dust cups at either or both key holes
to be fitted to it, and in such case the mode of fitting the cups as shewn in
figures 4 & 8.
Lastly I claim to make a watch that shall have any one or more or all of the
special features herein described as may be found desirable or necessary to meet
the requirements of the public.
