COMPLETE DI FUIFICATION
An Improved Door Stop and Catch.
1, JOHN MARSHALL of Gordon in the Colony of New South Wales, Draftsman,
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 has for its object the preventing of doors (more particularly those
in dwellings) from opening beyond a required distance, and retaining of same in
any desired position. It is simple in construction and cannot easily become
deranged. No stooping is required to release the door from the catch, foot pressure
being only needed. It can be fixed without the cutting of floor boards, carpets or
other floor coverings, and may be placed in any convenient position behind the
door.
To facilitate explanation I annex drawings:
-
Fig. 1 is a plan with the top foot lever removed, shewing the catch engaging
with a staple, secured to the bottom of a door.
Fig. 2 is a section at A. A.
Fig. 3 is a section at B. B.
Fig. 4 is a plan of a stop and catch, shewing the catch engaging with a plate
secured to the bottom of a door.
Fig. 5 is a side view of same.
Fig. 6 is a plan of a door stop and catch made principally of wood.
Fig. 7 is a section of same at C. C.
Fig. 8 is an end view of Fig. 4, shewing method of keeping foot lever in place.
In Figs. 1, 2 and 3, a is a case of metal, preferably of malleable cast iron, in the
bottom of which are the holes for screwing same to the floor, and on the bottom are
the claws c. In the claws c are secured the rubber buffers d to prevent shock when
the door strikes the stops. I prefer to press the rubber into the claws c and fasten
with shellac, but I may use any other suitable means or material for securing the
same object.
On the pin e, which rests in recesses in the side a of the case, is centered the
catch which is preferably of gun metal or cast steel, but may be of any other
suitable material, g is a spring beneath the catch to retain the catch in its normal
position. A foot lever fits over the case a and is hinged on the pin i and hooks
over the pinj to prevent it from rising too high, by means of the lugs k secured
inside the cover or foot lever, but I may also use other means than lugs for this
purpose such as slots and pins, or grooves and pins in front or sides of foot lever
and case.
A spring is placed inside the case a, under the foot lever to keep it raised in its
highest position, and to prevent jarring by the movement of the catch, this spring
may also be fixed to bottom of case, by means of the pins that hold the lower spring
in place and bent over end of catch and under foot lever.
The dotted lines in Fig. 2, shew the position of the catch when the front of foot
lever his pressed down.
In this form of door step and catch, the catch f engages with a staple m, shewn
screwed to the bottom of a door n.
In Figs. 4 and 5, the catch fis in advance of the claws the rubber buffers d
being secured in them as before to prevent shock. In this case, the catch fis shewn
engaging with a plate m screwed to the bottom of a door n, a part of which is cut
away to receive the catch.
.

page_text: In Figs. 6 and 7, the material used is principally wood, a is the case in the bottom
of which are the boles b for securing it to the Hoor; on blocks secured to the bottom
are fixed, by means of shellac and nails, or by any other suitable means, the rubber
buffers d.
h
A button passes through the top of the case on to the top spring which keeps
the button raised to its highest position.
The catch is retained in its normal position by means of the spring g, and jarring
of the catch is prevented by passing a screw o through a slot in the catch and
screwing it into the bottom of the case.
The catch is shewn engaging with a staple m, screwed to the bottom of a
door n.
To use the invention, it is screwed to the floor in any suitable position behind a
door; if the opening beneath the door is great, a block is placed beneath the door
stop and catch. On opening the door, the catch f engages with the staple or plate,
(as the case may be) on the bottom of the door, and retains it in a given position,
the buffers d preventing any disagreeable shock.
To release the door, pressure is brought to bear on the foot lever h by means of
the foot, as in Figs. 1, 2, 3, 4 and 5, or on the button has in Figs. 6 and 7, when
the catch fis depressed; and the door may be closed; on removing the pressure the
catch returns to its normal position.
I do not confine myself to the particular shape or size of door stop and catch
shewn on drawings, as, if desirable they may be modified or enlarged upon.
g
The method of fixing the parts together when made of metal is simple, the lower
spring 9 and pinj being fixed in place the spring g is bent down and the catch f
passed between it and the pinj; pin e is then inverted in catch and round the end
and over the latter the spring is placed with end resting on pin j, the foot lever is
then pressed down in front and then back so that the lugs come under pinj; the
back end of foot lever is then pressed down and the pin i fixed in position, but before
this is done the curve of spring g is pushed forward close to catch and in front of
pin. i, as the catch may be kept in place without further trouble by means of the
foot lever pressing down the spring on to the same.
The catch and pin e may also be made in one casting in which case a little more
space is necessary between the bottom of case and the pin j to permit the catch
being passed through from the back.
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 combination of the foot lever h and the spring 1, with the catch fand
spring g, substantially as shewn in Figs. 1, 2, 3, 4 and 5 and for the purpose set
forth.
2. The combination of the catch f with the case a and buffers d, substantially as
shewn in Figs. 1, 2, 3, 4 and 5 and for the purpose herein set forth.
and
3. The combination of the button and the spring l, with the catch
spring 9, substantially as shewn in Figs 6 and 7 and for the purpose set forth.
4. The combination of the catch with the case a and buffers d, substantially as
shewn in Figs. 6 and 7 and for the purpose herein set forth.
