PROVISIONAL SPECIFICATION.
Improvements in Spring-clasp Devices for Caskets, Jewel Boxes,
and the like.
I, ALOYS REVILLIOD DE MURALT of 2 Rue des Granges, Geneva, in the
Republic of Switzerland, Gentleman, do hereby declare the nature of this inven-
tion to be as follows:-
This invention consists of a simple and cheap spring clasp for caskets, jewel-
boxes and the like.
In the accompanying drawings I have shown how my said invention may be
conveniently and advantageously carried into practice.
Figure 1 is a cross-section of part of a casket and its cover provided with the
improved spring-clasp, showing the said cover partly shut.
Figure 2 is a similar section of the said casket showing the cover shut.
Figure 3 is a section on the line x-y of Figure 2.
Figure 4 is a perspective view of a half open casket provided with the improved
clasp.
Figure 5 is a similar view of the same when shut.
The Figures 6 to 10 show details of the different parts of the device detached.
The Figures 11 to 18 show different views of a somewhat different construction
of the same device.
The Figures 19 to 21 show different views of detached parts of the same.
Figure 22 shows another construction of the same device and
Figure 23 a detail of the pin belonging to the same.
The Figures 24 to 27 show different positions of the device shown in Figure 22.
Similar letters of reference indicate corresponding parts in the several figures of
the drawings.
A is the clasp proper which may be formed as a spring as shown in the
Figures 1 to 10 or combined with a separate spring A' as shown in the Figures 11
to 21 or with a spring G' as shown in the Figures 22 to 27 or with any other form
of spring.
The
The said clasp A is provided with a hole a which may be square, round, elliptical
or of any other suitable form, the edges of said hole being left sharp so as to firmly
grasp the pin B. The said pin may be of cylindrical square or other shape and is
fixed to the casket D if the clasp A is fixed to the cover E, and vice versa.
said pin B may consist of a simple nail or screw and the clasp A is suitably formed
and fixed to the cover E (or box D) so as to engage with its hole a over the said
pin B as shown in Figures 1, 2 and when the cover E is shut.
The sharp edges of the hole a grips the pin B and the clasp A being pressed
toward said pin B so as to produce such gripping (see Figure 2) the cover E will
be firmly closed. Any attempt to open the cover will produce a pressure upon the
spring-clasp A in the direction of the arrow 1 (Figure 2) and this pressure will
augment the gripping action of the clasp A on the pin B.
To open the casket or box it is only necessary to press the end of the clasp A in
the direction indicated by the arrow 2 in Figure 2 this pressure disengaging the
Baid clasp A from the pin B. The pin or stop C is intended to limit the down-
stroke of the clasp A.
As shown in Figures 11 to 21 the clasp A may be hinged at g to a plate G fixed
to the box, and acted upon by a separate spring A' fixed to said plate G. A
lateral projection A' is then provided to be acted upon when the clasp is to be
released.
The clasp A may also be hinged at g to an angular plate G as shown in the

page_text: Figures 22 to 27 and may be acted upon by spring-shaped arms G¹ of said
plate G.
In the above described arrangements the effect of the clasp is identical and the
spring acting upon the clasp A as well as the plate G may of course be varied at will.

COMPLETE SPECIFICATION.
Improvements in Spring-clasp Devices for Caskets, Jewel Boxes,
and the like.
I, ALOYS REVILLIOD DE MURALT, of 2 Rue des Granges, Geneva, in the
Republic of Switzerland, Gentleman, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This invention consists of a simple and cheap spring-clasp for caskets, jewel-
boxes and the like.
In the drawings left with my Provisional Specification I have shown how my
said invention may be conveniently and advantageously carried into practice.
Figure 1 is a cross-section of part of a casket and its cover provided with the
improved spring-clasp showing the said cover partly shut.
Figure 2 is a similar section of the said casket showing the cover shut.
Figure 3 is a section on the line x y of Figure 2.
Figure 4 is a perspective view of a half open casket provided with the improved
clasp..
.
Figure 5 is a similar view of the same when shut.
Figures 6 to 10 show details of the different parts of the device detached.
Figures 11 to 18 show different views of a somewhat different construction of
the same device.
Figures 19 to 21 show different views of detached parts of the same.
Figure 22 shows another construction of the same device and
Figure 23 a detail of the pin belonging to the same.
Figures 24 to 27 show different positions of the device shown in Figure 22.
Similar letters of reference indicate corresponding parts in the several figures of
the drawings.
A is the clasp proper which may be formed as a spring as shown in the
Figures 1 to 10 or combined with a separate spring A' as shown in the Figures 11
to 21 or with a spring G'as shown in the Figures 22 to 27 or with any other suitable
form of spring.
The said clasp A is provided with a hole a which may be square, round, elliptical
or of any other suitable form, the edges of said hole being left sharp so as to
firmly grasp the pin B. The said pin may be of cylindrical square or other shape
and is fixed to the casket D if the clasp A is fixed to the cover E, and vice versa.
The said pin B may consist of a simple nail or screw and the clasp A is suitably'
formed and fixed to the cover E (or box D) so as to engage with its hole a over
the said pin B as shown in Figures 1, 2 and 3 when the cover E is shut.
The sharp edges of the hole a grips the pin B and the clasp A being pressed
toward said pin B so as to produce such gripping (see Figure 2) the cover E will.
be firmly closed. Any attempt to open the cover will produce a pressure upon the
spring-clasp A in the direction of the arrow 1 (Figure 2) and this pressure will
augment the gripping action of the clasp A on the pin B.
To open the casket or box it is only necessary to press the end of the clasp A in
the direction indicated by the arrow 2 in Figure 2. this pressure disengaging the
said clasp A from the pin B. The pin or stop C is intended to limit the down-
stroke of the clasp A.

page_text: As shown in the Figures 11 to 21 the clasp A may be hinged at g to a plate G
fixed to the box, and acted upon by a separate spring A' fixed to said plate G. A
lateral projection A³ is then provided to be acted upon when the clasp is to be
released.
The clasp A may also be hinged at g to an angular plate G as shown in Figures 22
to 27 and may be acted upon by spring-shaped arms G¹ of said plate G.
In all the above described arrangements the effect of the clasp is identical and
the spring acting upon the clasp A as well as the plate G may of course be varied
at will.
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 is:-
1. The improved spring-clasp-device for caskets, boxes and the like formed
essentially of a clasp proper A having a hole a with sharp edges acted upon by
any suitable spring so as to grasp on a pin B fixed to the opposite part of the casket
or box which bears said clasp A substantially as and for the purpose specified.
2. In a spring-clasp device for caskets, boxes and the like a spring-clasp A
formed as shown in Figures 6 and 8 of any suitable size and of any suitable metal
having a sharped edged hole a.
3. In a spring-clasp device for caskets, boxes or the like the combination of a
clasp A formed as shown in Figures 19 to 21 having a sharp-edged hole a and
connected by means of a hinge g to a plate G with a spring A fixed to said
plate G.
4. In a spring-clasp device for caskets, boxes or the like, the combination of a
clasp A formed as shown in Figures 22 to 27 and having a sharp-edged hole a
connected by means of a hinge g to an angular plate G the spring shaped arms G¹
of which act upon said clasp A substantially as described with reference to
Figures 22 to 27 and for the purpose specified.
