PROVISIONAL SPECIFICATION.
Improvements in Pendent-setting Attachment for Watches.
I, JAMES JOHN ALLWARD, of the City of Hainilton, in the County of
Wentworth, Province of Ontario, Canada, Watch Maker, do hereby declare the
nature of this invention to be as follows:-
My invention relates to improvements in pendent-setting attachment in which
two levers pivotted and located between the upper and lower plates, and operated
by means of the ordinary winding or setting. stem, in regular cases, said levers
being held in proper tension by means of a. spring; and the objects of my
improvements are, first to provide a device capable of altering the action from
the winding of the main spring, to the setting of the hands; second, to afford
facilities for the accomplishment of the same.
I attain these objects by the mechanism illustrated in the accompanying drawing
in which:
Figure 1 is an elevation of the device as it appears when pressed down by the
common winding or setting stem of the watch case, to allow winding of watch.
Figure 2, is an elevation of the same when the winding stem is up, showing the
mechanism in position for the setting of the hands of watch.
The toothed wheel A, through which passes the lower part of the vertical pin B,
of the winding or setting stem, both of which form a part of regular watches and
cases, in common use. The upper lever C, which is pivotted to the plate of the
watch at 2, engages with the lower end of said vertical pin of stem at 3, which
when pressed down, as in Figure 1, the levers C and D, at 5, and 6, disengage.
These two levers when in winding action, are separated at 4, about the distance of
the depth of notch 6, in lever D.
This lower lever D, is pivotted to said plate at 7, and the notch or recess 6,
which is formed therein, being an important element.
The spring E which is secured to said plate, by means of screws 8, engages
with the outer and under part of lever C, at 9, and presses continually against said
lover, in order to give an upward pressure and certain tension to the same.
F, is the common yoke pin immediately over the regular stem winding wheels,
and H, an aperture in lower plate, through which the said pin F, passes, and is
ivetted to the common stem winding yoke situated on the reverse side of said
ower plate.
When the pin B is being raised by the outer winding stem, the spring E, exerts
ressure, and lifts the lever C, this causes the levers C and D, to lock in each
ther as in Figure 2.
The result of the vertical movement of lever D, is the vertical movement of the
in F, and the retaining of the same.
The upper position of this pin, facilitates the winding of the watch, and the
ower position facilitates the setting of hands of watch.
An important feature in this device, is the secure locking of the levers, after
hanging from winding, to setting of hands.
Dated this 30th day of June 1893.

page_text: I, JAMES JOHN ALLWARD, of the City of Hamilton, in the County of
Wentworth, Province of Ontario, Canada, Watchmaker, 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 :-
My invention relates to improvements in pendent setting attachment in which
two arms or levers pivotted and located between the upper and lower plates and
operated by means of the ordinary winding or setting stem in regular cases, said
levers being held in a proper tension by means of a spring; and the objects of my
improvements are, first, to provide a device capable of altering the action from
the winding of the main spring to the setting of the hands, and second, to afford
facilities for the accomplishment of the same.
I attain these objects by the mechanism illustrated in the drawing left with the
Provisional Specification.
Figure 1, is an elevation of the device as it appears when pressed down by the
common winding or setting stem of the watch case, to allow winding of watch.
Figure 2, is an elevation of the same when the winding stem is up showing
the mechanism in position for the setting of the hands of watch.
Similar letters and figures of reference refer to similar parts throughout the
several views.
A, is a toothed wheel through which passes the lower part of the pin B, both of
which form a part of regular watches and cases in common use. The pin Bis
held at proper tension by the pressure on the winding crown attached to a movable
notched stem which is located in the pendent, or neck, of the watch case and held
in position by a spring in said pendent or neck, said spring engaging in notches in
said stem. The upper or outer lever C, which is pivoted to the plate of the watch
at 2, engages with the inner end of said pin of stem at 3, which when pressed
down as in Figure 1, the levers C and D disengage at 5, and 6. These two levers,
when in winding action, are separated at 4, about the distance of the depth of
notch 6, in lever D. This lower or inner lever D is pivoted to said plate at 7,
and the said notch, or recess 6, which is formed therein, being an important
element.
The spring E, which is secured to said plate by means of screws 8, engages
with the outer and under part of lever C, at 9, and presses continually against said
lever in order to give an upward pressure and certain tension to the same.
F, is the common yoke pin immediately over the regular stem winding wheels,
and H an aperture in lower plate through which the said pin F passes, and is
rivetted to the common stem winding yoke situated on the reverse side of said
lower plate.
When the said pin B, of the winding or setting stem is being raised by the
action of the outer winding stem, the spring E, exerts, pressure at 9, and lifts the
lever C, this movement causes the levers C, and D, to lock in each other at 5
and 6, as in Figure 2. The result of the movement of lever D, as described, is
the movement of the said yoke pin F, and the retaining of the same in an outer
position, as in Figure 1, or in an inner position as in Figure 2.
The former, or outer position of this regular yoke pin F, facilitates the winding
of the watch; and the latter or inner position of the yoke pin facilitates the setting
of the hands of the watch.
This device is useful and is capable of a wide adaptation, in, that, it may be
placed in existing watches of various makes, and movements that are supplied
with stem winders, and watch hand regulators

page_text: Also a very important feature of this device, is the secure locking of the-
levers C, and D, after changing from winding of watch to the setting of, or
regulating of the hands.
My invention does not interfere with the common device known as the lever,.
for the purpose of changing yoke from winding to the setting of the hands, the
said lever can be used independent of my improvement.
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 I
claim is:
In a pendent setting attachment for watches, the pressure pin B, in combination
with the outer lever C, pivotted at 2, and the inner lever D, pivotted at 7, and
arranged to engage with each other at 5, and 6, said levers held in proper tension
by means of the tension spring E, which is secured to plate of watch at 8, and
engages with the said outer lever C, at 9, and the said inner lever D, at the same-
time engaging with the yoke pin F, which is secured to regular stem winding:
yoke, substantially as described and set forth.
