Improvements in and Connected with Drawer and other Knobs.
I, HARRY ISRAEL HUMPHRY, of 86, Balsall Heath Road, Edgbaston, Warwickshire,
Wood turner, do hereby declare the nature of this invention to be as follows:-
This invention has reference to those knobs of wood, china, or other substance which
are fixed, for instance to a drawer front, by a central screw passing from the inside
through the front of the drawer and screwed into the knob.
In the case of wooden knobs these screws are commonly made of wood the knob
being screw threaded inside to receive them. If the knob is screwed up very tightly
the thread either on the knob or screw or both is often stripped, thereby rendering the
knob useless which defect it is the chief object of my invention to overcome.
In carrying out this invention as applied for instance to fixing a wooden knob to a
drawer, I employ a metal screw which is passed from the inside of the drawer through
the front thereof as usual. Embedded in the knob I employ a metal nut of a size
to fit the screw this nut is by preference square to prevent its turning round and
fits in a circular recess in the front of the knob, this recess being filled up by a
wooden or other plug. The said screw is headed and is by preference formed with a
square or other neck or projecting part or parts to prevent its turning round. The
knob is fixed to the drawer front in the usual way by being presented against the
projecting threaded end of the screw and turned round when the screw will engage
with the nut which is embedded in the knob and the knob will be firmly fixed in position.
By the screw and the nut being made of metal there is little or no possibility of their

in the foot of the knob through which the screw passes is a plain hole and does not
require to be screw threaded, the cost of producing the knob is considerably reduced
and by making the said central plug in the front of the knob of a different colour or
substance to that of which the body of the knob is formed, adds considerably to the
appearance of the same.
In most cases I bore a central hole in the plug from the inside for the end of the
screw to enter so that a long screw can be used to enable the knob to be fixed to
drawer fronts of different thicknesses.
My invention can be applied to earthenware, china and other knobs similarly as
above described with reference to a wooden knob.
My invention can also be similarly applied for the fixing of wooden, china, earthen-
ware and other knobs for mortice or other lock furniture the knob spindle being screw
threaded and taking into the nut in the knob as above described with reference to a
screw.

COMPLETE SPECIFICATION.
Improvements in and Connected with Drawer and other Knobs.
I, HARRY ISRAEL HUMPHRY, of 86, Balsall Heath Road, Edgbaston, Warwickshire,
Wood Turner, 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 has reference to those knobs of wood, china, or other substance which

through the front of the drawer and screwed into the knob.

the thread either on the knob or screw or both is often stripped, thereby rendering the
knob useless which defect it is the chief object of my invention to overcome.
In carrying out this invention as applied for instance to fixing a wooden knob to a
drawer, employ a metal screw which is passed from the inside of the drawer through

fit the screw this nut is by preference square to prevent its turning round and fits in

to the drawer front in the usual way by being presented against the projecting
threaded end of the screw and turned round when the screw will engage with the

By the screw and the nut being made of metal there is little or no possibility of

hole and does not require to be screw threaded, the cost of producing the knob

In most cases I bore a central hole in the plug from the inside for the end of
the screw to enter so that a long screw can be used to enable the knob to be
fixed to drawer fronts of different thicknesses.
My invention can be applied to earthenware, china and other knobs similarly as
above described with reference to a wooden knob.
On the accompanying drawing Fig. 1 represents in sectional elevation a knob con-
structed and fixed to a drawer in accordance with this invention; Fig. 2 is a front
view of the knob, and Fig. 3 is also a front view with the filling up plug removed;
Fig. 4 illustrates the parts of the same and the fixing screw separately.
The same letters of reference indicate the same parts in all the figures of the
drawing.
a is the wooden or other knob and b is the metal nut embedded therein by being
passed down the central recess c in the front of the knob this recess being afterwards
filled by the wooden or other plug d. e is the drawer front and f is the headed metal
fixing screw, constructed in any usual manner and preferably so that it will not turn
round, which is passed from the inside of the drawer through the front e so that its
screwed part projects, and against this screwed part the knob is presented and turned
so that the screw will engage with the nut band when the knob is screwed home it
will be firmly fixed in position. The metal nut may be either of a square, hexagonal,
or other shape so as to prevent its turning round, and when the knob is made of wood
the recess c is preferably circular and the nut made of such a size that its corners will
groove the sides of the recess as the nut is pushed down to the bottom thereof and thus
be embedded therein and prevented from turning round. The small recess d¹ in the
plug d is for the end of the screw to enter when the knob is fixed to a thin drawer
front, door, or the like.
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
1. The combination with a wooden, china, earthenware, or other non-metallic knob,
of a metal nut embedded therein to engage with a metal fixing screw entering the
hole in the foot of the knob, for the purpose and substantially as hereinbefore

page_text: 2. The herein described improved wooden, china, earthenware, or other non-metallic
knob provided with a square, hexagonal or other shaped metal nut & fitting in the
recess c, which latter is closed by the plug d made with or without the recess d¹, for
the purpose and substantially as hereinbefore described and illustrated by the accom-
panying drawing.
