A New or Improved Door Fastener.
I. REGINALD HARRY GAMSÓN, of 15, Alma Terrace, Silver Hill, St. Leonards-
on-Sea, in the County of Sussex, Gentleman, do hereby declare the nature of
this invention to be as follows:-
This invention relates to an improved door-fastening device, and in accordance
therewith, I provide a bent spring consisting of a steel or other resilient plate
bent at one end back upon itself to form a spring wedge, the front end of the
upper arm of such spring wedge being bent downward at an approximate right-
angle. This bent down or right-angled end of the said upper plate, is of such
a length as to allow the lower edge of same to reach down to, immediately in
front of, the forward edge of the under arm of the spring wedge. The said
lower edge of the downwardly bent end of the upper arm is serrated, so that when
the spring wedge is inserted with its thin or acute-angled end beneath a door,
pressure from the outside of such door (such as an attempt at forcing it) will
depress the top arm of the wedge, and so force the serrated edge of the turned
down end of said top arm, firmly into the floor.

A New or Improved Door Fastener.
I. REGINALD HARRY GAMSON, of 15, Alma Terrace, Silver Hill, St. Leonards-
on-Sea, in the County of Sussex, Gentleman, 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 relates to an improved door-fastening device, and has for its
object to provide an article of this description, which, when inserted beneath a
door from the inside, for instance, will prevent such door being opened from the
outside, no matter what pressure of force is employed to open such door, a further
object being to provide a door-fastening device which will be simple of construc-
tion, durable in use, and inexpensive to produce.
And in order that this my said invention may be the more readily understood
and carried into practical effect, reference is hereby made to the accompanying
sheet of illustrative drawings, wherein :-
Fig. 1, is a perspective view of the device, shewn independently.

page_text: Fig. 2, being a similar view of the device from another position, while,
Fig. 3 illustrates in side elevational view the device in position beneath a door.
Referring to the drawings, wherein like letters of reference indicate corre-
sponding parts throughout several figures, a b represent the two members of the
device, which is preferably formed by bending a rectangular strip of steel or
other resilient metal at a point somewhat nearer one end than the other, and
turning one of the members a so produced back upon the other b, thereby forming
a spring wedge, the upper member of which is normally in an upwardly inclined
position from the rear to the front.
The forward end of the upper member a is turned down at an approximate
right angle to the main portion, as at a', the lower or horizontal edge of which
turned-down part being serrated as at a².
The under member or base plate 6 is shorter in length than the upper member a,
and the lower serrated edge of the turned-down end a¹ is so arranged as to
project immediately in front of the forward edge of the base-plate or lower
member b.
In operation, the spring wedge so formed, is inserted, thin end c foremost,
beneath the door d, as far as it will conveniently go, the member of the spring
wedge resting upon the floor.
When pressure is brought to bear upon the door for the purpose of opening
same, the upper member a is depressed thereby, which has the effect of forcing
the serrated edge a² into the floor and fixing the device in an immovable position,
as will be readily seen by Fig. 3.
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:
The improved door-fastening device, consisting in a rectangular strip of resilient
metal bent at a point nearer one end than the other, to form two members, one of
which is turned back upon the other to form a spring wedge, the upper member
of which is longer than the lower member, and has its forward end turned down
at an approximate right angle to the main portion, the lower edge of said turned-
down end being serrated and arranged to project immediately in front of the
forward edge of the lower member, substantially as and for the purpose described
and as illustrated by the drawings.
