IMPROVEMENTS IN CUPBOARD AND OTHER DOOR FASTENINGS
Year: 1885

page_text: I JOSEPH WALKER of 4 Regent Parado Birmingham in the County of Warwick
Brass Founder, do bereby declare the nature of my invention for IMPROVEMENTS
IN CUPBOARD AND OTHER DOOR FASTENINGS to be as follows:-
This Invention consists of an improved spring latch, which is placed on the.
inside of the door, and is operated on by means of a knob on the outside; the knob
being connected to the latch by means of a spindle passing through the door the
said spindle forming the axis or pivot upon which the latch turns.
It somewhat resembles the ordinary cupboard turn, improved in such a way
that its action is perfectly automatic besides being simple & effective.
The tongue or body of the latch is preferably placed about parallel with the
meeting joint of the door, and has a bevelled projection on the side at its extremity
which overlaps the meeting joint for the purpose of securing the door the bevel
part being for the purpose of causing it to yield automatically as it comes into
contact with the other door or frame as the door is being closed, after which the
spring forces the latch back behind the other door or frame and secures it.
For the purpose of keeping the latch in its proper position and of limiting its
movement, the said latch is slotted, or has two projections between which slot or
projections a fixed pin is driven into the door, the said pin limiting the move-
ment of the latch to the length of the slot or the distance between the two
projections.
Ór this may be done by a staple driven in the door over the latch the move-
ment being limited according to the width of the staple, in either of the above
arrangements the pin or staple may serve as an abutment for the spring which
is preferably attached to the latch.

page_text: I JOSEPH WALKER of 13 & 14 Augusta Street Birmingham in the County of
Warwick Brass Founder do hereby. declare the nature of my invention for
IMPROVEMENTS IN CUPBOARD AND OTHER DOOR FASTENINGS and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
In the accompanying drawings
Fig. 1 shews an elevation of the latch when fixed on the inside of the door.
Fig. 2 shews a section through the centro of the latch.
This invention consists of an improved spring latch A which is placed on the
inside of the door B and is operated on by means of a knob C on the outside, the
knob being connected to the latch by means of a spindle D passing through
the door, the said spindle forming the axis or pivot upon which the latch turns. It
somewhat resembles the ordinary cupboard turn improved in such a way that its
action is perfectly automatic besides being simple and effective.
The tongue or body E of the latch is preferably placed about parallel with the
meeting joint F of the door and has a bevel projection G on the side at its
extremity which overlaps the meeting joint for the purpose of securing the door,
the bevel part being for the purpose of causing it to yield automatically as it comes
into contact with the other door or frame as the door is being closed, after
which the spring H forces the latch back behind the other door or frame &
secures it,
For the purpose of keeping the latch in its proper position and of limiting its
movement the said latch is slotted as shewn at I (or has two projections) between
which slot or projections a fixed pin J is driven into the door (or attached to a
plate fixed thereto) the said pin limiting the movement of the latch to the width of
the slot or the distance between the two projections, or this may be done by a
staple driven in the door over the latch or by two pins driven on each side the
latch the movement being limited according to the width of the staple or according
to the distance the two pins are placed apart in all of the above arrangements the
pin may serve as an abutment for the spring which is preferably attached to the
latch.
The method of fixing the handle to the spindle is by an ordinary set screw, lock
nut, or other suitable method.
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 spring latch working upon a pivot the said pivot being in such a position

page_text: rebound to fasten itself at the back of the door or frame by means of a spring as
substantially set forth.
2. A spring latch of the description above described limited in its movement by
means of a slot & pin or staple or two pins as substantially set forth.
3. A spring latch consisting of the parts arranged & combined as substantially
set forth & illustrated by the accompanying drawings.
