I THOMAS JEPSON, of 62 Ebury Road, Sherwood Rise, Nottingham, Commercial
Traveller do hereby declare the nature of this invention to be as follows:-
My invention has reference to keyless watches, that is to say, watches which are
wound by a stem which passes through the pendant and is turned by means of a
milled head or button. In these so-called keyless watches a difficulty has been
experienced in securing the bow to the pendant because a screw such as that used for
securing the bow in other watches cannot be employed. It has been usual to spring
the bow into place its ends then entering holes in the sides of the pendant, but this
mode is imperfect.
Now the object of my invention is to so construct the parts that the bow as well as
the winding stem can be readily and perfectly secured. With this object I divide
the pendant horizontally into two parts the upper or outer part being made of
diminished diameter at its inner end so as to fit into the lower part. The bow is
secured in the upper part of the pendant and this may be conveniently effected by
forming the pendant at each side with a slot extending up a certain distance from its
lower edge and by passing up these slots the necks of two bosses on the ends of the
bow; these bosses may consist of the heads of two screws which are screwed into the
ends of the pendant, their heads being left projecting a little. Through the lower
part of the pendant I form a hole for a screw or pin to pass through from back to
front and in that portion of the upper part which fits into the lower part I form
corresponding holes so that the screw or pin passes through them also and thus when
in place secures the two parts of the pendant together and therefore also secures the
bow. The position of the holes is such that the side of the screw or pin which is
passed through them enters a groove formed around the winding stem and therefore
while leaving this free to be rotated prevents its being pulled out. If the winding
stem fits into an inner pipe of the pendant this pipe must have a piece cut away to
give passage to the screw or pin.

page_text: I, THOMAS JEPSON of 62 Ebury Road, Sherwood Rise, Nottingham, Commercial
Traveller, 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 has reference to keyless watches that is to say watches which are
wound by a stem which passes through the pendant and is turned by means of a
milled head or button. In these so-called keyless watches a difficulty has been
experienced in securing the bow to the pendant because a screw such as that used for
securing the bow in other watches cannot be employed. It has been usual to spring
the bow into place, its ends then entering holes in the sides of the pendant, but this
mode is imperfect.
Now the object of my invention is to so construct the parts that the bow as well as
the winding stem can be readily and perfectly secured. With this object I divide the
pendant into two parts, the upper part being made of diminished diameter at its inner
end so as to fit into the lower part. The bow is secured in the upper part of the
pendant and this may be conveniently effected by forming the pendant at each side
with a slot extending up a certain distance from its lower edge, and by passing up
these slots the necks of two bosses on the ends of the bow; these bosses may consist
of the beads of two screws which are screwed into the ends of the bow, their heads
being left projecting a little. Through the lower part of the pendant I form a hole
for a screw or pin to pass through from back to front and in that portion of the upper
part which fits into the lower part I form corresponding holes so that the screw or
pin passes through them also and thus when in place secures the two parts of the
pendant together and therefore also secures the bow. The position of the holes is
such that the side of the screw or pin which is passed through them enters a groove
formed around the winding stem and therefore while leaving this free to be rotated
prevents its being pulled out. If the winding stem fits into an inner pipe of the
pendant this pipe must have a piece cut away to give passage to the screw or pin.
Figure 1 of the annexed drawings is a sectional view of so much of a keyless watch
as is necessary to illustrate my invention. Figure 2 is a section taken at right angles
to the section represented in Figure 1, Figure 3 is a section on the line of
Figure 1, Figure 4a view of the lower portion of the pendant, Figure 5 a view of
the upper portion of the same and Figure 6 a view of the bow. All the figures are
on an enlarged scale. a is the watch case, b and c are the pendant which is made in
two parts as hereinbefore described, the lower part b being secured to the watch case.
d is the bow. The portion c¹ of the part c of the pendant is made with longitudinal
slots e extending up from its lower edge and this portion is of smaller diameter than
the part of the pendant so that it may fit therein as seen in Figures 1 and 2. The
part has two notches corresponding in position with the slots e in the part c. is

intervening necks 11; these bosses can be most conveniently formed in the manner
shown, that is to say by means of screws screwed into the ends of the bow, their heads
being left projecting a little. m is a screw or pin passed through holes in the
parts b and c of the pendant to secure them together, the screw going right through
from one side to the other. The position of the holes is to one side of the middle so
as to clear the winding stem g; this stem is, however, formed with a groove n
through which the pin m passes so that the pin not only secures the parts b and c of
the pendant together but also secures the stem g while leaving this free to be rotated.

mode of securing the winding stem, that is to say by a pin or screw passed through
the pendant at one side of the middle of same and through a groove in the stem is
applicable to keyless watches in which the pendant is not divided.
The parts are put together as follows. The bow d is first placed upon the part b of
the pendant with the boss necks 11 resting in the notches ff; the part of the pendant
is then pushed into the part in such manner that the slots ee pass over the necks
the bosses kk being within the part c'. The bow is consequently secured in the
pendant. The winding stem is next inserted and finally the pin or screw m which
Secures all in place.
Figure 7 represents a modification of my invention in which the bow with its
necked bosses instead of being placed upon the part of the pendant and secured by
the part has its ends sprung into the part through holes made for the
purpose and is then secured by the partc (shown attached in Figure 8) which is
pushed into the part as before and has slots ee to pass over the boss necks Il. The
parts and c and winding stem g are secured by a pin or screw as in the modification
first described.
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 in respect of keyless watches is :-
1. A bow with a necked boss at each end in combination with a slotted piece
inserted into the pendant in such manner as to secure the bow by means of the bosses,
substantially as herein before described.
2. A winding stem having a groove around it in combination with a pin or screw
passed through the pendant and through said groove in such manner that it secures
the stem in place while leaving it free to be rotated, substantially as hereinbefore
described.
3. The combination of the pendant part b, the slotted part c, the necked bosses on
the bow d, the groove n in the winding stem and the pin or screw m passed through
the pendant and through the groove h, substantially as hereinbefore described and
shown in the annexed drawings.
4. Constructing koyless watches as hereinbefore described and shown in the
annexed drawings.
