An Improved Catch for Boxes, Trunks, Drawers, Doors, and such like.
Year: 1899

page_text: PROVISIONAL SPECIFICATION.
An Improved Catch for Boxes, Trunks, Drawers, Doors, and such like.
I, DAVID WADDELL, of 93, Hamilton Street, Motherwell, in the County of
Lanark, North Britain, Tinsmith, do hereby declare the nature of this invention
to be as follows:-
This invention relates to an improved catch for boxes, trunks, drawers, doors,
and such like where a staple is used through which a padlock, or in some cases
a pin, is required to retain the flap in its proper position so as to prevent the
lid of the box, or such like flying open when not desired.
In carrying out my invention, I carry round the staple either in the inside or
outside a metal spring, one end of which is fixed to the staple, while the other
end passes through an opening or slit, or openings and slits, and is loose, so that
whenever the flap is pushed down over the staple it presses in the end of the
spring until it, the flap, passes over it when the spring comes out, and being
above the edge of the flap, it acts as a lock or catch, in a manner somewhat
similar to an umbrella spring. When the box or such like, is to be opened, the
spring is simply pressed in when the flap can be lifted over the staple in the
ordinary manner
The staple may be riveted, soldered, or otherwise fixed in its proper position.
The staple may be riveted, soldered,
or otherwise fixed in its proper position.

COMPLETE SPECIFICATION.
An Improved Catch for Boxes, Trunks, Drawers, Doors, and such like.
I, DAVID WADDELL, of 93, Hamilton Street, Motherwell, in the County of
Lanark, North Britain, Tinsmith, 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 relates to an improved catch for boxes, trunks, drawers, doors,
and such like where a staple is used through which a padlock, or in some cases
a pin, is required to retain the flap in its proper position so as to prevent the
lid of the box, or such like flying open when not desired.
In order that my invention may be properly understood and readily carried
into effect, I have hereunto, appended one sheet of drawings, of which,
Figure 1 illustrates a box or such like receptacle to which my improved catch
is applied.

page_text: Figure 2 is a part transverse section of the box shewing the flap and catch in
their normal locked position, drawn to an enlarged scale, and
Figure 3 is a similar view showing the catch with its engaging spring pushed
in in order to release the flap, which last position is shewn in dotted lines in
this figure, all hereafter more fully described.
In carrying out my invention, I carry round the staple A in the inside or on
the outside a metal spring B, bent to the curvature of the staple, one end of
which is fixed to the staple A, while the free end passes through openings or
slits in the said staple A, to the outside and enters again by another slit a¹
where the said free end is bent back and is loose, so that whenever the Hap C is
pushed down over the staple A it presses in the free end of the spring B until
The hinged flap passes over it when the spring B comes out, and being above
the edge of the flap C, it acts as a lock or catch, in a manner somewhat similar
to an umbrella spring.
When the box D) or such like is to be opened, the spring
is simply pressed in by the extremity of the thumb or finger, as seen in Figure 3,
when the Hap can be lifted over the staple in the ordinary manner.
The staple A may be rivetted, soldered, or otherwise fixed in its proper position.
I may dispense with staple and fix spring to box.
-
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
The improved catch constructed and operating substantially as and for the
purposes herein before described and shown on the accompanying sheet of
drawings.
