PROVISIONAL SPECIFICATION.
Improvements in Door and Window Fastenings.
HENRY HAWGOOD 13 Westbourne Terrace Sutton Lane Chiswick W.
Furniture Salesman do hereby declare the nature of this invention to be as
follows:-
The fastener is made of iron or other metal and is in the shape of a hinge, one
plate of which is fixed upon the door post in the jamb, the other part swings inside
the room and back against the architrave when not in use. When turned flat
against the door (when closed) it is fastened in that position by a small lever or
button which is rivited to the swing plate and turned against a small shoulder
forming part of the plate screwed to the door post. For window fastening, it is
fixed in the ordinary position locking against the lower sash.
The fastener is made in three pieces, the shank Fig. I. A, the swing plate B, and
the lever (or button) C. The shank A is screwed to the door post in the jamb, and
is connected to the swing plate B on the hinge principal, a pin passing through a
hollow cylinder divided into five parts, three of which are formed in the shank A,
and two parts in the swing plate B, the centre part of cylinder E of the shank A
extends outward to form a shoulder and has a small groove F which the lever (or
button) C touches into when locked, the swing plate B is so shaped between its
two parts of cylinder to allow it to clear the shoulder when passing. A lever
(or button) is rivetted at D to the swing plate B one end of which when turned
against the shoulder and into the groove F securely prevents the door from being
opened from the outside.
Fig. II shows the position of the fastener locked, the shank is in the jamb showing
only its three parts of cylinder A and the shoulder E, the swing plate B is turned
against the door, and the lever (or button) C is turned against the shoulder E
(and into the groove F) of the shank A. The plate D (of any ornamental design)
is only used for additional strength and is fixed upon the architrave butting close
to cylinder, the small knob G facilitates the turning of the lever (or button) C for
door fastening.
Fig. III shows the position of the fastener when open and turned back against
the architrave of door. For window fastening, the lever (or button) is rivetted to
the centre of the swing plate, is smaller, and has no knob.
The inventor claims the principal of a "swing plate" fastened to the door post
(or outer sash between the two for window fastening) which when turned flat
against the door (or fellow "sash" for window) can, by means of a lever, button,
spring, catch, or other contrivance fixed to itself, be securely fastened in that
position.
ADVANTAGES.
The fastening of the door from within, without any attachments or fixings of any
kind to the door.
The process of fastening is very simple and noiseless, in many cases this new
fastening can be fixed in one minute as the shank mostly passes between the door
(when closed) and the jamb of the door post, otherwise it should be cut into the
latter.
When the fastener is used at the top part of door and out of reach the
lever (or button) can be raised with a short stick by pushing the small knob

page_text: Fig. II G upwards, the action of the door opening, places the swing plate back in
position.
Can be made of ornamental designs, and as cheaply as bolts.
When used for window fastening, it cannot be unfastened from the outside
without first breaking a window.

HENRY HAWGOOD 13 Westbourne Terrace Sutton Lane Chiswick London W.
Furniture Salesman 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 fastener is made of brass, iron, or other metal, either stamped out of wrought
plate, or cast, in three pieces, viz., the shank Fig. I. A, the swing-plate B, and the
lever (or button) C. The shank A is shaped like a dovetail and is screwed to the
door post in the jamb with one screw, and is connected to the swing-plate B on the
hinge principal, a pin passing through a hollow cylinder divided into three parts, one
of which is formed in the shank A, and two in the swing-plate B. That part of the
shank A. marked with a dotted line shows where the door closes (the inside of door
when closed), and through that part to the left, the cylinder passes. There is a
groove at the shaded part E into which the end of the lever (or button) C enters.
The lever (or button) C is rivetted to the swing-plate B and when the swing-plate
is turned against the door, the lever (or button) is turned in an horizontal position
and the end marked with a dotted line enters the groove E in the shank A and
fastens the swing-plate in that position.
Fig. II shows the fastener as fixed in the jamb upon the door post, as viewed
from the opposite post with the door open. The shank A is cut into the jamb H if
necessary, the dotted line shows the inside of door when closed, the swing-plate B
with the lever (or button) C shows the position unfastened.
Fig. III is a sectional position of the fastener when unfastened and turned back
against the architrave, H the door post, K the door.
Fig. IV shows the fastener with the swing-plate B turned against the door, the
dotted line showing where the door closes (the jamb), the lever (or button) C is
turned in an horizontal position the end of which enters the groove of the shank A
at the dotted quadrant, and secures the swing-plate in that position. The "stop" F
a part of the swing-plate B prevents the lever (or button) passing beyond the
position required. The lever (or button) C turns upon a rivet passing through
both the lever (or button) and the swing-plate, the head of rivet Ġ being on the
lever (or button).
Fig. V. is a sectional position of the fastener, the door, and the door-post when
fastened as in Fig. IV. The shank A, the swing-plate B, the lever (or button) C,
the head of pin passing through the cylinder D, the dotted line E shows where the
lever (or button) enters the groove of the shank A, the stop F, the door K, the
moulding upon the architrave M, the door stop N.
The fastener can be used to fasten window sashes, fixed upon the lower rail of
the outer (or upper) sash in the usual position, the swing-plate when turned over
on-to the top rail of the inner (or lower) sash, and the lever (or button) adjusted
securely prevents the inner sash being raised, or the outer sash being lowered.
The advantages are, a very strong fastener for the inside of doors (opening
inwards), and for window sashes. No fixings or attachments whatever to the door,
or lower (inner) sash of window, only one screw required to fix, is ornamental,
noiseless in adjusting, and cannot be picked.

page_text: 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 :
I. The principle of fastening doors and window sashes, without any attachments
or fixings upon the door, or inner sash of windows.
II. The principle of a swing-plate attached to a plate fixed upon the door post in
the jamb, upon the hinge principle, or by means of a pin passing through a
cylinder divided between each, the plate fixed upon the door post, and the swing-
plate, in three parts, as in the drawings supplied with this Specification, or more.
III. The principle of fixing the swing-plate when turned against "the door," or
for window sash fastening the "inner sash," by means of a lever, button, or other
contrivance, fixed to itself (the swing-plate).
