Improvements in and relating to Snap Fasteners for Jewel Cases.
I, CHARLES WILLIAM CHENEY, of 104, Vyse Street, in the City of Birmingham,
Die Sinker and Tool Maker, 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;-
This invention is an improved snap fastener for jewel cases and a simple attach-
ment means for connecting it to the lid or other part of the case, the object of
the invention being the construction of a fastener, which will not necessitate any
fitting in its attachment to the case, as is necessary with the fasteners now in
use, and which will not consist of any loose parts; the result being that the
fastener could be supplied to the jewel-case maker as one part necessitating only
a simple knocked-in staple or plate for its attachment.
the
The snap fastener according to this invention is shown in the accompanying
sheet of drawings fixed in position on the inside of the lid of a jewel case,
said drawings representing a complete case in elevation in Fig. 1 with the
fastener shown in position by dotted lines, an enlarged section of a portion of
the lid with the fastener attached in Fig. 2, the said fastener being also in
section, an inside elevation of Fig. 2 in Fig. 3, a cross-section of Fig. 2 on a
dotted line in Fig. 4, and a seperate view of the body part of the fastener in
Fig. 5.
A right angled metal plate e having a cut-out leg on its inner branch and
a hook part and a pusher c¹ upon its outer branch forms the body of the
fastener, the said plate being fitted to the front under-side of the lid a
by its
pusher passing through a clearance hole a in the front edge and its inner
branch being held upon the inner face a³ of the lid by a metal strap & which
crosses its one end, and whose ends are forced into the lid in the manner shown
in Fig. 4. The strap d and the clearance hole form guides for the travel of the
fastener when forced inwards into the position shown in dotted lines in Fig. 2,
and they render the said fastener strong and true in its action.
A coil spring
encircles the leg and controls the fastener in its holding position against
being forced inwards, the said spring being confined between the junction of the
leg with the inner branch of the fastener and a turned down lip upon the
strap d, the end of the said leg taking through a hole in the said lip so as to
slide therethrough freely. By means of the turned down lip the strap is con-
nected to the fastener so that the whole of the said fastener and the means for
attaching it is a single part.
To attach the fastener in position it is only necessary to bore out a hole such
as a² and introduce the pusher from the inside, and force the ends of the strap
into the wood, it being unnecessary to in any way hollow out the inner surface a³
of the wood of the lid to let in any part of the fastener to form abutments for.
certain of its working parts.
In some cases the leg could be dispensed with, and a cut-away part similar
to the one m Fig. 5, but narrower, could be formed in the angle piece e in its
stead, into which is let a flat zig-zag spring which takes its abutments against

being formed however so as to overlie the spring to keep it in position in the
cut-away. part.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
First. A snap fastener for jewel cases comprising a right angled piece e having
made fast with it a leg and a pusher ‹³, or a pusher only, the said pusher
engaging a hole such as a, a strap for holding part of c to the jewel case and a
spring g, all working substantially as described and set forth.
Second. A snap fastener for jewel cases constructed and fitted to the case in
the manner substantially as set forth in Figs. 1 to 3.
