"IMPROVEMENTS IN SNAPS OR FASTENINGS FOR NECK CHAINS, NECKLACES, NECK
RIBBONS OR BANDS, BRACELETS, AND OTHER LIKE ARTICLES."
My Invention consists in constructing and arranging the parts of the said snaps
or fastenings in the manner herein-after described, whereby a very secure and
durable fastening is obtained, and the connecting together and disconnecting of
the two ends of the neck chain or other like article are effected with great
facility.
One part of the snap or fastening consists according to my Invention consists
of a tube or barrel closed at one end, the closed end being furnished with an eye
or loop, to which one end of the neck chain or other article is connected. The
other or front end of the tube or barrel is closed, excepting by an opening for the
passage through it of the "click" or other part of the snap.
In a longitudinal slot in the said tube or barrel of the snap a small lever works.
That arm of the said lever which is presented to the open or front end of the
barrel is cranked or bent at right angles, the said bent or cranked part projecting
into and crossing the barrel at a short distance from the opening in the front end.
Under the opposite or rear arm of the lever is a spring, by means of which the
lever is made to take its normal or fastening position. On the upper side of the
rear arin of the lever and near the end thereof is a stud which projects a little above
the outside of the barrel. By pressing upon this stud the lever may be turned on
its joint, and its front and cranked end raised in the barrel.
The other part or "click" of the snap to which the opposite end of the neck
chain or other like article is connected consists of a flat shank having on one end
a loop or eye, and at the other end a head bevilled or inclined on its upper side
or face.
The opening in the front end of the barrel of the snap is of a size and figure
to mancies the hand and shank described of the click part

introduced into the opening in the front end of the barrel part. As the click enters."
the barrel, its bevilled head coming against the bottom of the cranked end of the
spring lever in the barrel, lifts the said crank end, and when the click has been
pushed completely home in the barrel, the shoulder of the inclined head is brought b
opposite the cranked end of the lever, when the said cranked end, by the action of
the spring at the opposite end of the lever, snaps behind or engages with the said
shoulder of the head, and the two parts of the snap are fastened securely together.
By pressing down the rear end of the lever by the stud on its outer side the
cranked end of the lever is lifted from the shoulder of the head of the click part, 1
when the latter is released, and may be withdrawn from the barrel part and the
two parts of the snap disconnected.
