LEO E. DONNELLY AND JOHN H. LOONEY, OF ITALY, TEXAS.
STEM WINDING AND SETTING WATCH.
SPECIFICATION forming part of Letters Patent No. 613,411, dated November 1, 1898.
Application filed June 8, 1897. Serial No. 639,904. (No model)To all whoim it may cOnCC7'f:
Be it known that we, LEO E. DONNELLY
and JOHN H. LOONEY, citizens of the United
States, residing at Italy, in the county of El-
5 lis and State of Texas, have invented a new
and useful Winding and Setting Mechanism
for Watches, of which the following is a speci-
fication.
This invention relates to mechanism for
io winding and setting watches by means of the
pendant, and is applicable to open or hunting
case watches, and has for its objects to reduce
the primary cost of such mechanism both as
to material and time required for fitting it to
15 the movement and case, to secure the mov-
able part of the pendant against displace-
ment and loss, to simplify the construction
and reduce the operating parts to a minimum
number, and to supply a mechanism for the
20 purpose aforesaid which will be effective, du-
rable, easy of manipulation, and not liable to
derangement.
For a full understanding of the merits and
advantages of the invention reference is to
25 be had to the accompanying drawings and the
following description.
The improvement is susceptible of various
changes in the form, proportion, and the mi-
nor details of construction without departing
30 from the principle or sacrificing any of the
advantages thereof, and to a full disclosure of
the invention an adaptation thereof is shown
in the accompanying drawings, in which -
Figure 1 is a view in elevation of a watch-
35 movement, showing the application of the in-
vention, the mechanism being in position for
winding the spring. Fig. 2 is a view similar
to Fig. 1, showing the mechanism as it will
appear when moved to a position for setting
40 the hands. Fig. 3 is a transverse section
through the pendant and parts intimately
associated with the winding and setting mech-
anism. Fig. 4 is a transverse section of the
pendant on the line X X of Fig. 1. Fig. 5 is
45 a top plan view of the fixed portion of the
pendant. Fig. 6 is a detail perspective view
of the outer or movable part of the pendant.
Corresponding and like parts are referred
to in the following description and indicated
So in the several views of the accompanying
drawings by the same reference characters.
The watch-movement comprises a train ofgearing of any type, of which the spur-wheel
applied to the arbor of the winding-spring is
represented by the numeral 1 and the idler 55
intermeshing with the pinion on the post
bearing the hands is indicated by the refer-
ence character 2, said movement being in-
closed in a case provided with a pendant com-
posed of a boss 3 and a movable part 4, hav- 6o
ing the bow 5 applied thereto.
The yoke 6 is mounted upon a flanged col-
lar 7, placed upon a screw 8, let into a plate
9 of the movement, and is provided at one end
with a spur-gear 10 to mesh with the idler 2, 65
as shown in Fig. 2, when the mechanism is in
gear for setting the hands, and at its opposite
end with a spur-gear 11, normally intermesh-
ing with the spur-gear 1 to admit of the spring
being wound when required to maintain the 70
movement in running order. A spring 12 is
secured at one end to the plate 9, and its op-
posite end enters a notch formed in an edge
of the yoke and exerts a pressure on the lat-
ter sufficient to maintain the spur-gears 1 and 75
11 in meshing relation.
The yoke 6 is formed with an extension 13,
projecting toward the pendant and provided
with a lateral extension 14, adapted to be en-
gaged by a lug or projecting part 15 at the So
inner end of the hollow shank 16, forming a
part of the movable portion of the pendant,
whereby upon turning the latter the yoke is
vibrated upon its pivotal support to bring the
spur-gears 2 and 10 into engagement to en- 85
able the hands of the watch to be moved. The
master-gear 17 is concentric with the pivotal
support of the yoke and meshes with the spur-
gears 10 and 11 and is formed on its inner
face with a crown-gear meshing with the 90
bevel-pinion 18, receiving the inner angular
end of the stem 19,which is rotatably mounted
in the pendant and has connection at its outer
end with the crown 20, by means of which
the stem is rotated for winding or setting the 95
watch, as desired.
The boss 3 is rigidly applied to the casing
and is formed with a longitudinal bore which
is internally threaded. The outer edge of the
boss is reduced, and its outer end is formed moo
with an annular groove 21 to receive the in-
ner ends of screws 22, passing longitudinally
through openings formed in the movable part
4 of the pendant. The end portions of the
