This invention relates to band attachment
means for wrist watches. The object of the in
vention is to provide a simplified means for at
taching or connecting the ends of. a wrist band
5 or strap to a wrist watch. The construction of
the improved device is such as to greatly facili
tate the attachment or removal of the wrist band
and provide a secure and positive means of at
tachment so that the possibility of the watch
becoming inadvertently disconnected from the
wrist band and accordingly lost will be avoided.
According to present construction, the opposite
ends of a wrist watch are each provided with a
pair of lugs between which a rod or bar extends
15 and the same passes through a permanently
formed loop on the end of the wrist band. The
rod or bar which connects the two lugs is usually
provided with spring-pressed studs at its ends
which snap into engagement with holes provided
An arrangement of this character
is of relatively delicate construction, and to dis

connect the ends of the wrist strap or band when
it is desired to replace the band, often requires
the use of tools.
Also, it often occurs that when
25 replacing a wrist band the studs do not firmly
engage the holes in the lugs and the band be
comes later inadvertently disengaged from the
watch and the watch lost.
With my improved Wrist band connection
30 means, the cross bar or rod extending between
the lugs may, if desired, be made integral with the
lugs and may thus be of sturdy construction.
Also, with my improved connection means, the
ends of the wrist band may be very easily engaged
(ci. 24-265)
In the drawing, I indicates the case of a wrist
watch of conventional construction, such case
being provided ateach of its ends with the two
spaced lugs indicated at 2, connected by the
cross bar or rod 3 in the usual way. This cross
bar or rod 3 may be of the removable kind, or it
may be a permanent member extending between
the two lugs 2 and formed integral therewith.
The wrist band or strap 4 may be formed of any
suitable flexible material such as leather, fabric, 10
or the like, and it is preferably composed of
several layers or plies, two of which are shown
at 5 and 6 which are stitched together at their
edges along longitudinal lines as at -I. Sand

sti?fening member 8 held in position by means of
the stitches 5 and 6 and also by means of trans
versely extending stitches 9 and I i), or other addi
tional stitching if necessary.
The position of the strip 8 before being bent
or doubled over to loop formation is shown in
Fig. 5. Near one of its ends the strip 8 is pro
vided with a pair of spaced, upwardly extending
spring projections or tongues II and it is. also
provided with additional projections I2 and I3
separated from the projections I I by means of an
intervening space I4. All of the projections II,
I2 and I3 are formed by distorting the metal of
the body of the strip 8.
The band 4 is provided near its end with a
cut-out opening I5 extending through the ply 5
and through which that portion of the strip pro
vided with the various projections I I, I2 and I3

and hold it against inadvertent displacement. It
will remain in the space I4 until it is manually
drawn over the spring tongues II and moved in
a direction away from the Watch when it is de
sired to remove the band from its attachment to
the watch.
The metal comprising the strip 8 is
of sufficient stiffness to cause the band to main
tain its looped portion, and the loop I'I, locked in
position in the space I 4 as heretofore described,
provides a closed loop affording a secure means
for holding the ends of the wrist band attached to
the watch.
