Improvements in Catches for Show Case Doors and Casements, and
for other like purposes.
I, JOHN CHARLES TAYLOR, of 46, Haringey Road, Middle Lane, Hornsey,
in the County of Middlesex, Mechanic, 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 relates to a catch for show cases, cabinets, doors and for other
like purposes so constructed as to be strong and durable and easily fitted with
its striking plate into the edge of the door and frame of the show case or other
article.
In the accompanying drawings, Fig. 1 is an elevation of the striking plate and
part of the jamb or framing. Fig. 2 is an elevation of portion of a door showing
the socket G for receiving the catch, and Fig. 3 is an end elevation of same,
Fig. 4 is a sectional plan through the door and its jamb or framing showing the
parts in the closed position. Fig. 5 is an elevation of the catch and Fig. 6 is a
plan of the same.
The catch is contained in a cylindrical casing or tube A having a box B formed
on or secured to the upper end thereof. In the cylindrical casing or tube A is
a solid catch bolt C having a shoulder projection or lug c at or near the upper end

in diameter to admit a helical spring D which is coiled, and around it with its
upper end bearing against the larger diameter of the bolt C with its lower end
bearing against the bottom of the cylindrical casing or tube A or against lugs
on, or a screw pin or rivet a passing diametrically across the bottom of the
tube A as shown in Figs. 4 and 5.
In the box B is pivotted at e2 a lever handle the outer end e of which projects
through the box and forms the handle for the catch while the inner end e¹ rests
on the top of the shoulder projection or lug c on the catch bolt C so that the latter
will be retracted into the tube A against the power of the spring 1) when the lever
handle is raised on its pivot e². is a top plate covering both the cylinder or
tube A and the box B and provided with holes f through which screws or other
fastening devices may be passed to secure it to the wood of the door, flap or the like.
To fit the catch it is only necessary to bore a socket G just large enough to
receive the tube A in the edge of the door, flap or the like by means of a centre or
other bit and to bore a recess on each side thereof with the same tool to receive the
sides of the top plate F. Then by means of a suitable tool a part of the socket G can be
cut away as shown in Figs. 3 and 4 to receive the box B. The catch may then be
easily fitted in and will remain in proper position, screws or other fastening devices
being passed through the holes f to prevent the catch from falling out of the
socket G when the door, flap or the like is so opened that the edge to which the
catch is fitted hangs downwards.
The striking plate H I prefer to make as a segment of a circle rather larger
than a semi-circle and to receive same I correspondingly recess the jamb by means
of a centre or other bit. When fitted in its segmental recess the striking plate
will not be easily displaced.
By constructing my catch in the manner hereinbefore described I obviate the
necessity for undercutting or recessing the face of the material to which the catch
is fitted and dispense with the handle plate usually fixed in such undercut or
recess and which frequently oxidizes or discolours by exposure. I also secure a
strong and powerful spring catch of a simple and economical form which occupies
but little space and which can be quickly and readily fitted.
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:
-
1. A catch for show cases, cabinets, doors and for other like purposes consisting
of a cylindrical casing or tube with a transverse box, a bolt fitting said casing or
tube and having a shoulder or lug projecting into said box a reduced diameter
at the lower end of said bolt, a helical spring surrounding said reduced diameter,
a lever pivotted in said box with one end resting on the shoulder or lug on the bolt
and the other end projecting outside the box and forming a handle, substantially
as described.
2. A catch for show cases, cabinets, doors and for other like purposes constructed
and fitted to operate substantially as and for the purposes hereinbefore des-
cribed and illustrated in the accompanying drawings.
