PROVISIONAL SPECIFICATION.
Improvements in Combined Door Stops and Door Holders.
I FREDERIC HUGHES of No. 20 Paget Road, West Dulwich in the County
of Surrey Mechanical Engineer do hereby declare the nature of this invention to
be as follows:-
My invention relates to an apparatus for automatically stopping and holding the
doors of buildings, houses & institutions of all kinds thereby preventing damage
to walls from the door furniture, and the slamming of doors by sudden draughts
when open frequently involving the breakage of glass where the doors are glazed.
For this purpose I construct in brass, iron or other suitable material a narrow
oblong box "A," with broad flat top for fixing on floor, as shewn by accompanying
drawing. In this box the bolt or hold fast "B," and the stop "C," are fixed; the
former working on a pivot "D" and the latter capable of sliding in a horizontal
direction. The bottom of the said holdfast is made with a concave curve & the
upper face of elongated foot of stop with a convex curve to fit same: consequently
when the stop is pushed back horizontally by the opening of the door a cam like
action occurs which causes the holdfast to fly up & retain the door in position;
and when the stop is moved back in the opposite direction the hold fast is lowered
to the level of the top of its box and the door released.
Dated this 20th day of October 1894.
FREDERIC HUGHES.
Improvements in Combined Door Stops and DOUT
I, FREDERIC HUGHES, of 20 Paget Road, West Dulwich, London, Engineer, 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 :-
The object of my invention is to provide a simple and efficient means whereby a
door, window sash, or the like may be held in position when opened.
In order that my invention may be clearly understood, I proceed to describe the
construction and action thereof with reference to the accompanying drawings
which represent my improved door stop in sectional elevation; Fig. 1. showing the
stop, closed, and Figure 2, the stop open.
The catch a is pivoted in box b which is fixed in the floor in required position to
hold the door open. The stop c preferably covered with rubber or the like to
minimise concussion has a horizontal arm c capable of movement to and fro along
the box band provided with a projection d engaging with corresponding recess in «,
but when the door or the like is brought up against stop the same is pressed back
and the projection d assumes the position shewn in Figure 2 raising the catch a
and preventing reverse movement of the door until an opposite pressure is brought
to bear upon stop c to release the catch a and allow it to fall to its normal position
as shewn in Figure 1.

page_text: Although I have described my invention as applied to a door, it is evident it is
equally applicable to windows or for similar purposes.
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 :-
