I, HARRIS HARDING FASSETT, of 318, California Street, San Francisco, California,
U.S.A., Inventor, do hereby declare the nature of this invention to be as follows:-
:-
This invention relates to that class of door catch especially applicable for
retaining swing doors in closed position.
The object of the invention is to provide a door catch which will be of simple
and durable construction and cheap to manufacture.
A door catch constructed in accordance with the herein described improvements
comprises a socket adapted to be sunk into the door jamb and be retained in
A hollow or solid rubber ball is
place by screws on other suitable means.
retained within the socket by means of a substantially semi-circular cap which
covers the ball and is formed with a flange engaging behind a flange or lugs on
the periphery of the socket in such manner that the cap and ball can be compressed
into the socket. A concave plate is secured to the edge of the door opposite to
the cap and socket.
When the door closes, its edge will come forcibly into contact with the cap
and compress the ball until the concave plate comes opposite to the cap which
will then be forced into it.
In an alternate device the socket and cap are of semi-circular section and of
any suitable length; the ball being replaced by a piece of thick rubber tubing.
If desired, the cap can be dispensed with and the rubber ball or tube be retained
in the socket by means of an adhesive substance or by other suitable means;
but the cap will be found desirable as a protection from wear due to friction.
In yet another alternative form, the socket is of suitable length, and has a
rod journalled in its ends, and a piece of compressible tube passed over the rod
to work in contact with the concave or grooved plate on the edge of the door.

page_text: The object of my invention is to provide a door catch which will be of simple
and durable construction and cheap to manufacture.
Reference being had to the accompanying drawings;-
Fig. 1 is a horizontally taken section through my improved door catch and so
much of a door frame and door as will serve to illustrate my invention.
Fig. 2 is a front view of one part of my device, and Fig. 3 is a similar view
of the other part thereof.
Fig. 4 is a front view of an alternative form of the device, and Fig. 5 is a plan
view of its counterpart.
Fig. 6, is a horizontally taken section through the device illustrated in Figs. 4
and 5 and so much of a door frame and door as will serve to shew my invention
in operative position.
My improved door catch comprises the metal socket 1 in the opening of which
the annular rib 2 of the ring 3 can be readily inserted.
A solid or hollow flexible
ball 4 is retained within the socket by means of the disc 5 which is shaped to
conform to the contour of the disc and has a flange 6 to retain it beneath the
inner edges of the ring 3.
When applying the device to a door way a recess 7 is formed in the door
frame 8, by means of a large boring-bit, in order to recess the ring 3 flush with
the frame. By means of a smaller boring-bit the recess 9 is formed to seat the
socket 2. The parts are then assembled as shewn and secured from displacement
by the screws 10. The counterpart, consisting of the concave disc 11 is recessed
into the door 12 as shewn.
It will be readily understood that as the door swings, the disc 5 will be forced
inwards at each swing until the door ultimately remains at rest in the closed
position shewn in Fig. 1.
In Fig. 4 the socket 2 is rectangular, as is also the counterpart 11 to conform
therewith. Both the socket and its counterpart are recessed into the door frame
and door respectively so that their faces are flush therewith. Instead of the
compressible ball, however, I employ a section of rubber or like tubing 13 which
is passed over a metal pin 14 extending longitudinally of the socket as illustrated.
The operation of this form of my device is precisely the same as that described
with reference to Fig. 1.
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 3
I claim is:
1. A door catch consisting of a metal socket adapted to be recessed into a door
frame, a compressible ball seated in said socket, a disc conforming to the shape
of the ball and having its edges seated beneath a ring covering the disc and
socket, said ring adapted to be recessed into and be secured to the door frame, 4
and the counterpart consisting of a disc having its face concave recessed into the
door, all substantially as and adapted to operate as described and as illustrated in
the drawings hereunto attached.
2. A door catch consisting of an elongated rectangular socket having outwardly
extending side flanges, a pin extending longitudinally and centrally between the 4
ends of the socket, a section of compressible tube placed over said pin and the
counterpart consisting of a rectangular plate having a concave face, all sub-
stantially as and adapted to operate as described and as illustrated in the drawings
hereunto annexed.
