COMBINATION OF DOOR KNOCKERS WITH GONGS OR BELLS AND METHODS OF EFFECTING SUCH COMBINATION
Year: 1884

page_text: I ROBERT HENRY HEPBURN of 66 Oakley Square Regents Park in the County
of Middlesex Engineer do hereby declare the nature of my invention for THE
COMBINATION OF DOOR KNOCKERS WITH GONGS OR BELLS AND METHODS OF
EFFECTING SUCH COMBINATION to be as follows:-
My invention primarily consists of the novel combination of a door knocker
with a gong or bell in such manner that a person in the act of using the knocker
shall necessarily sound the gong or bell.
Thus
According to one method of effecting this combination I fit to the inside of the
door behind the knocker a gong the upper end of which is suspended from an arm
on the door while its lower end is held to the door by means of a spring. Through
the door in line with the point against which the knocker strikes I form a hole
and I construct the knocker with a prolongation which passes through the said
hole and bears against the gong and in fact forms its hammer or striker.
when a person raises the knocker and thens lowers it so as to knock in the usual
way the prolongation or hammer thereon is first lifted away from the gong and
then made to strike it forcibly while the knocker itself strikes the door. I prefer
to dispense with the metal piece against which the knocker is usually made to
strike;
the knocker thus strikes against the wood of the door so that an
objectionable loud knock cannot be given and the sound of the knock may be
further deadened by applying leather or other suitable substance to the part
against which the knocker strikes.
According to another way of effecting the combination I fit to an arm or bracket
on the inside of the door a bent lever one arm of which carries a striker to strike
against a gong or bell which is likewise fitted to the inside of the door; the other
arm of the bent lever has an extension which passes through and extends beyond
a hole in the door so as to impinge against the striking part of the knocker. Thus
when the door is knocked the knocker acts through the bent lever on the striker
and strikes the gong or bell.
In combining a door knocker with an electric bell I fit the ordinary button,
which requires to be acted on in order to make the necessary contact, in a hole
in the door formed as before described so that when the door is knocked the
knocker forces in the button, makes the contact and rings the bell. Or the
knocker may have at its upper part an extension which passes through a hole
in the door and makes the requisite electric contact when the knocker is raised as
will be readily understood.

of Middlesex Engineer do hereby declare the nature of my invention for THE
COMBINATION
OF DOOR KNOCKERS WITH GONGS OR BELLS AND METHODS OF
EFFECTING SUCH COMBINATION and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
My invention primarily consists of the novel combination of a door knocker
with a gong or bell in such manner that a person in the act of using the knocker
shall necessarily sound the gong or bell.
According to one method of effecting this combination I fit to the inside of the
door behind the knocker a gong the upper end of which is suspended from an arm
on the door while its lower end is held to the door by means of a spring. Through
the door in line with the point against which the knocker strikes, I forin a hole
and I construct the knocker with a prolongation which passes through the said
hole and bears against the gong and in fact forms its hammer or striker. Thus
when a person raises the knocker and then lowers it so as to knock in the usual
way the prolongation or hammer thereon is first lifted away from the gong and
then made to strike it forcibly while the knocker itself strikes the door.
prefer
to dispense with the metal piece against which the knocker is usually made to
strike; the knocker thus strikes against the wood of the door so that an
objectionable loud knock cannot be given and the sound of the knock may be
further deadened by applying leather or other suitable substance to the part
against which the knocker strikes.
Figure 1 of the annexed drawings represents in side elevation the method above
described of combining a knocker and gong. a is the door shown in section.
bis the knocker. c is the gong suspended from the arm d and held to the door
at its lower end by means of the spring e. f is the prolongation on the knocker
which passes through a hole in the door and bears against the middle of the gong,
forming its hammer or striker. Figure 2 represents a modification in which the
hammer strikes against the edge of the gong c which is held to the door by
means of a central support g.
According to another way of effecting the combination I fit to an arm or bracket
on the inside of the door a bent lever, one arm of which carries a striker to strike
against a gong or bell which is likewise fitted to the inside of the door; the other
arm of the bent lever has an extension which passes through and extends beyond
a hole in the door so as to impinge against the striking part of the knocker. Thus
when the door is knocked, the knocker acts through the bent lever on the striker
and strikes the gong or bell.
Figure 3 represents this way of combining a knocker and gong. is the bent
lever fitted to the arm i on the door a; one arm of the lever carries the striker f
of the gong c and the other arm has an extension ke which passes through a hole
in the door and impinges against the striking part of the knocker b. Figure 4
represents a modification in which the gong c is in line with the striking part of
the knocker b; the piece k against which the knocker strikes passes through the
support of the gong and when acted upon by the knocker actuates the striker f;
the striker is carried on the end of a spring arm f' pivoted at f³ and in the inward
movement of the piece the projection thereon pushes against the projection m
on the arm f¹ forcing this arm from the gong until the projection by passing m
enables the arm to rebound so that the striker f will strike the gong. The return

movement of the piece is effected by the spring n and in order that the
projection may in returning pass the projection m the arm f' is given a certain
freedom of movement sideways on its pin at f.

raised
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 :-
1. The combination of a door knocker with a gong or with a bell in such
manner that a person in the act of using the knocker shall necessarily sound the
gong or bell, substantially as herein before described.
2. The several modes hereinbefore described of combining door knockers with
gongs or bells.
