COMPLETE SPECIFICATION.
A New or Improved Catch or Fastening for Doors, Desk or Box
Lids, Gates, and the like.
I, WILLIAM JOHN MIDELTON, of Harston, near Cambridge, Surgeon, 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 enable doors, lids, covers, or gates, to be
retained in an open position, and relates particularly to such doors or lids as are
controlled or closed by means of a spring.
In order that the nature of my invention, and the manner of performing same
may be readily understood, I will proceed to describe with reference to the
accompanying drawings, the manner in which it is to be carried into effect.
Fig. is a sectional elevation, shewing my improved apparatus attached to a
door u.
This door a is held open or in the position shewn by means of the catch C
engaging with the catch B.
If the door is pushed until the catch C reaches the point D and then the door
is left to itself, the catch C slides over the curved piece A and pushes the arm BE
into a position approximately represented by the dotted lines B' E' thereby allowing
the door to close.
A spring or other buffer F G may be employed to regulate the movement of the
door, especially when no other spring is employed.
The curved piece A can only be moved through a limited space, this being
regulated by the stop s.
In causing the door to be held open as well as in closing when once open, it is
not necessary to manipulate the device with the hands, a simple push on any part
of the front of the door being sufficient. It is thus obvious that this device
constitutes a double action catch.
When it is required to convert the catch into a single action for closing the door
when once held open the curved piece A may be dispensed with, and a small weight
attached to the arm B E at the end E, sufficient to cause the said arm to be brought
into the required position.
In the case of a door or the like controlled by a spring or its equivalent, it will
be understood that the spring exerts sufficient force to keep the catches B and C
together, while the door is in an open position, but when the door is required to
be closed the aforesaid weight will pull down the end E and consequently raise the
catch at the other end away from the catch C. The catch rod B E may be
secured to the wall by means of a small bracket or plate H between which it
(the catch rod) is pivoted at 1, and its movement may be controlled by the
stop J.
It is obvious that this invention is equally applicable to all kinds of doors, as
well as to the lids of desks, boxes, or other receptacles, gates or the like, and that
the two parts may be interchanged as to the object to which they are attached,
i.e. the catch C may be fixed to the wall and the remainder of the appliance to
the door, although I prefer the arrangement as described in the foregoing
Specification.
