IMPROVEMENTS IN WATCH MOVEMENTS
Year: 1884

Manufacturer do hereby declare the nature of my invention for IMPROVEMENTS IN
WATCH MOVEMENTS to be as follows:-
This invention has for its object the construction of watches which will allow of
the going barrel being removed without removing the top plate, the balance spring
stud being adjustable nearer to or further from the centre of the balance, and the
rocking bar in keyless watches being movable for setting the hands without the
aid of a pushpiece.
The opening for the barrel in the top plate is larger than usual and sufficient
to allow the barrel to pass through. This opening may be concentric with the
barrel arbor pivot holes in the plates or excentric to them, or it may be semi-
circular and curved.
When, as is usual, that part of the topplate between the centre pinion pivot bole
and the barrel is so close to the edge of the barrel as to cover or partly cover tho
barrel teeth the barrel must be moved from under the top plate to pass out through
the opening. To effect this the pivot hole of the arbor in the pillar plate may be
sufficiently larger than the end of the arbor beyond the said pivot that when the
pivot is out of the hole the smaller end may have room in the hole to allow the
barrel to move from under the topplate into the said opening; or the hole or a
part of it may be made movable to effect the same result. This large pivot may be
a part of the arbor or be preferably a collar fitted to the arbor, or be formed on the
finger piece of the stopwork.
The studholder is preferably attached to the arm of the balance cock, and has, a
hole through ita perpendicular which receives the stud of the balance spring and
another hole through its side which receives a screw the end of which acts upon
the stud to keep it in the hole. The studholder may be secured to its support. by
friction or by a screw and may be adjustable in its place by one or more screws or
pins. The part of the holder that fits into the opening made for it may be round
or square or oblong or V shape or dovetail shape in its cross section..
-
The arm of the keyless rocking bar which is acted upon by the pushpiece may
be extended through the edge of the plate and sufficiently beyond to allow of the
sethands being effected without the use of a pushpiece.

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 :-
The construction of watches with a going barrel that may be removed without
removing the topplate; the balance spring stud to be adjustable nearer to or
further from the centre of the balance and the rocking bar in keyless watches to
be movable for setting the hands without the aid of a pushpiece.
The opening for the barrel in the topplate is larger than usual and sufficient to
allow the barrel to pass through. This opening may be preferably excentric to the
centre of the barrel or it may be semi circular and curved.
The teeth of the going barrel next to to the centre pinion are within a perpendicular
line of the opening in the topplate and to allow the barrel to get into the opening
to pass through it must be shifted from under the topplate. To effect this the pivot
hole of the barrel arbor in the pillar plate may be preferably made as much larger
than the end of the arbor outside the hole that when the pivot is out of the hole
the said end may have room in the hole to allow the barrel to move from under
the topplate and pass through the opening; or the hole or a part of it may be
made movable. This large pivot may be a part of the arbor or be preferably a
collar or pipe fitted upon the arbor, or when there is a stopwork the pivot of the
finger piece should be made large enough to serve the purpose it being necessary
that such large pivot be as much larger than the square or outside end of the arbor
as the barrel is covered by the overhanging plate.
The studholder is preferably attached to the arm of the balance cock and has a
hole through its perpendicular which receives the stud of the balance spring and
another hole through its side which receives a screw the end of which acts upon
the stud to keep it in the hole.
The studholder may be secured to its support by friction or by a screw and may
be adjustable in its place by one or more screws or pins. The part of the holder
that fits to the opening made for it on the cock or elsewhere may be round or
square or oblong or V shape or dovetail shape, a corresponding shape in the latter
case being desirable for the part that it fits to.
The arm of the keyless rocking bar which is pushed by the pushpiece may be
extended through the edge of the plate and sufficiently beyond to allow of the set-
hands being effected without the use of a pushpiece.
DESCRIPTION OF DRAWINGS.
Figure 1 represents the topplate and the barrel in its place. A is the barrel and
B the excentric circle which is large enough to let the barrel teeth pass through.
When the barrel is shifted from its present position into the centre of the circle B
it will be removable and pass through. The dotted lines by B show the size of the
circle.
Figure 2 represents a barrel in its place in the pillar plate and the dotted lines
at (a) shew the top plate overhanging the teeth (e) of the barrel. A collar or pipe
pivot (c) is fitted upon the arbor at (t) friction tight and moves freely in the hole
of the pillar plate B. When the barrel is raised the collar leaves the plate, and
before the teeth (e) have reached the top plate A at (a) is out of the hole. The

page_text: outer end of the arbor (d) then is able to be moved in this large hole sufficiently
for the barrel to be shifted from under the topplate at (a) into the opening in the
top plate through which it passes.
Figure 3 shews the pillar plate B with a movable hole. An oblong sink is
made in the pillarplate commencing at half of the barrel hole as at (a) figure 6 and
opposite to the centre wheel. A hole representing three sides of a square as at (c)
figure 6, is made right through the plate, and a slide. (d) figure 5 is fitted into the
sink shown also in section at (d) figure 3. This slide is shaped at (c) to form half
a hole and when in its place as in figure 4 it makes a complete hole for the arbor
of the barrel and is held in its place by a screw (n) upon the removal of which
screw the piece (d) slides away from the arbor and allows it room to shift the
barrel from under the top plate as before described.
Figures 8, 9, 10 represent an adjustable stud which is attached preferably to the
arm of the cock figure 7 at A the two sides (o) of which arm are shaped dovetail
shape to correspond to the sides of tho stud as shewn at (o), figure 9. The stud
figure 11 fits to the hole (a) figures 8 & 10 and is held there by a screw (c) which
is on the outside of the stud when the studholder is on the arm of the cock as
shewn at (c) figure 8. The holder is kept secure upon the arm of the cock by the
screw (d) figures 9 & 10, and the holder may be moved to any required place upon
the arm of the cock, nearer to or farther from the centre and then secured by the
screw head (d). A screw (e) without any head may be fitted to the side nearest
the balance centre and made to project as much as such side is from the cock and
to allow of a nicer adjustment of the position of the stud. A pin may answer the
same purpose-its end being filed to the required length.
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
1 To construct a watch having the following characteristics.
2 A going barrel that may be removed from its place without necessitating the
removal of the topplate, by making the hole in the pillar plate or a part of it
movable; or by making the pivot of the barrel arbor which may be solid or movable
or of the stopfinger that fits to the pillarplate as much larger than the end of tho
arbor outside the pivot as may be necessary so that when the pivot is out of tho
hole in the pillar plate the end of the arbor may have room in the hole to let
the barrel shift from under the topplate.
3 A stud holder which may be attached to the balance cock or other support
without necessitating the stud to be held by such support or secured to it.
4 An adjustable stud or stud holder for the balance spring which may be adjust-
able to or from the centre of the balance, the stud being either a part of the holder
or separate the shape of the holder at that part which is held by the support to
be either round, square, V shape or dovetail shape as may be preferred and to be
held in its place by friction or a screw or other means preferred-the drawings
being intended to represent one application of the principle.
5 An extension of the rocking bar of keyless watches, or that arm of it which
may be most convenient, to the outside of the movement to allow it to be moved
for setting the hands without a pushpiece.
Finally a watch with either or all of these improvements as circumstances and
the public needs may require.
