Specification Accepted, 16th Feb., 1889
We ALFRED EDWARD HARRIS and HOWARD JOSEPH LUCкOCK both of 95 Camden
Street Birmingham in the County of Warwick Stampers and Piercers 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:-
:―
"
Our invention has for its object improvements in spring catches for doors and is
particularly applicable for use in cabinets pedestals and cupboards the door when
closed being reatained in its position in such a manner that it may be readily opened
without the manipulation of a knob or its equivalent this being effected by our catch
which is both simple in construction and cheap in production and which having
no loose parts is certain in its action and cannot get out of order even after
long use.
In order that our invention may be clearly understood and more easily carried
into practice we have appended hereunto a sheet of drawings upon which we have
shewn one of our improved catches applied to the door of a cabinet together with
various details which fully illustrate the device.
.
Figure 1 is a sectional plan through the door A and one side B of a cabinet or
pedestal shewing the door closed.
Figure 2 is a similar sectional plan to Figure 1 but shewing the door slightly
open.
Figure 3 is a section through the catch.
Figure 4 is a plan of the same.
Figure 5 is an end elevation of the same.
Figure 6 is an inverted plan of same.
Figure 7 is front elevation of the catch plate.
Figure 8 is an end elevation of same.
Figure 9 shews a modification of the form of spring.
The box D is stamped out of a piece of sheet metal or cast into the shape shewn
and is provided with two three or more screw holes d', d, and d³ to allow of being
fixed to the door A.

page_text: A portion of the box D is cut away to allow the catch E to be inserted and have
freedom of movement the catch being provided with two cars e¹ and e² which are
mounted upon the pin F each end of which is mounted in the sides of the box D
in such a manner that the said catch E has freedom to turn. Around the pin F
the coiled wire spring H is placed leaving the end butting up against the
catch E which in turn buts against the edge d' of the slot in the box D which
forms a stop the other end of the spring running under the case and entering the
side of the box D which fixes it. The spring F by these means has a constant
tendency to press against the catch E and as the whole coil of the spring. is at
work a lasting durability is obtained. Instead of having the spring H formed of
coiled wire we may substitute a flat steel spring as shewn by Figure 9.
The head of the catch is formed into the curl e³ which engages with the catch
plate K which is secured to the side B as shewn and thereby retains the door in its
closed position but allows of it being pulled open in which case the action is a shewn by
Figure 2.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed I declare that what I
claim is
In the improvements in spring catches for doors the arrangement substantially as
herein set forth and shewn upon the drawings.
