PROVISIONAL SPECIFICATION.
Improvements in the Construction of Knobs or Door Handles and in
Adjusting and Attaching them to Spindles.
I WILLIAM EDWARD RILEY of 6 Carlyle Avenue The Hoe Plymouth in the
County of Devon Civil Engineer and Associate Member of the Royal Institute
of British Architects do hereby declare the nature of this invention to be as
follows:-
According to this invention, the knob or handle is fixed to the spindle by a
screw tapped into the end of the spindle and passing through the front of the knob.
In applying this invention, I use a square spindle tapped or bored at the ends
and knobs or handles with plain square holes in the neck thereof for the spindle to
take into, and on the front of knob a hole is provided to allow the adjusting screw
to pass into the spindle tapped to receive it and a sunk recess to accommodate the
head of the adjusting screw and secure it in position.
In adjusting the knobs and attaching to the spindle, the knob on one side is fixed
and the spindle passed through the fitting to which it is intended to be applied, and
the knob passed over the projecting spindle, they being secured by a screw which
is driven until the knob is adjusted to the required position; to prevent the screw,
attaching the knob to the spindle, from turning, after it is adjusted, two dovetailed
grooves are cut across the head, and in these are slotted small dovetailed slips, a
portion of which pass into holes in the sides of the sinking or recess in the outer
front of the knob, which accommodates the head of adjusting screw, and are secured
in the position thus determined by a smaller screw tapped into the head of the
large adjusting screw, which is thus locked in the position in which it has been
finally adjusted. Any convenient means may be employed for locking this screw
in position.

COMPLETE SPECIFICATION.
Improvements in the Construction of Knobs or Door Handles and in
Adjusting and Attaching them to Spindles.
I WILLIAM EDWARD RILEY of 6 Carlyle Avenue Plymouth in the County
of Devon Civil Engineer and Associate Member of the Royal Institute of British
Architects 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 :-
According to this invention the knob or handle is fixed to the spindle by a screw
tapped into the end of the spindle and passing through the front of the knob.
In applying this invention I use a square spindle tapped or bored at the ends,
and knobs or handles with plain square holes in the neck thereof for the spindle to
take into, and on the front of knob a hole is provided to allow the screw to pass
into the spindle tapped to receive it, and a sunk recess to accommodate the head of
the adjusting screw, and secure it in position.
In adjusting the knobs and attaching to the spindle, the knob on one side is fixed,
and the spindle passed through the fitting to which it is intended to be applied,
and the knob passed over the projecting spindle, they being secured by a screw
which is driven until the knob is adjusted to the required position; to prevent the
screw, attaching the knob to the spindle, from turning, after it is adjusted, two

page_text: dovetailed grooves are cut across the head, and in these are slotted small dovetailed
slips, a portion of which pass into holes in the sides of the sinking or recess in the
outer front of the knob which accommodates the head of the adjusting screw, and
are secured in the position, thus determined, by a smaller screw tapped into the head
of the large adjusting screw which is thus locked in the position in which it has
been finally adjusted.
Figure 1 of the accompanying drawing represents in section a door knob in
position after adjustment (a) is the rose, (b) is the spindle, (c) is the knob, (d) is
the screw adjusting the knob in its required position and securing it to the spindle,
(e) is the smaller screw tapped into the head of the large adjusting screw for locking
it to the knob.
Figure 2 shews a plan of the front of the knob with screws (d) and (e) and the
position of the holes in the sides of the recess, or sinking, for accommodating the
dovetailed slips and for locking the large adjusting screw in its final position.
Figure 4 shews an elevation of the adjusting screw (d) and, by broken lines,
the smaller screw (e) let into the head of it, also the dovetailed slot into which the
small dovetailed slips are placed for locking it in position after adjusting the knob
on the spindle.
Figure 3 shews an elevation of one of the dovetailed slips a portion of which
passes into holes in the side of the sinking or recess accommodating the head of the 2
adjusting screw.
Figure 5 shews an elevation of the smaller screw which is tapped into head of
adjusting screw.
One or both knobs may be adjusted in the manner described in this invention.
The knobs or handles may be of any convenient shape and made of any suitable 2
material such as wood, metal, or earthenware, the rose may be of any shape and
either a separate piece or secured to the knob or handle before it is adjusted.
The knobs may be ornamental and the adjusting screw either fixed in a recess,
as described, or made projecting and ornamented.
Having now particularly described and ascertained the nature of my said inven- a
tion, and in what manner the same is to be performed, I declare that what I
claim is
Improvement in the construction of knobs or door handles and attaching them to
spindles by means of an adjusting screw passing through the front of the knob into
the end of the spindle and thus accurately adjusting its position and securing it to 3
the spindle so that the strain required to turn the spindle is borne mainly by the
neck of the knob substantially as hereinbefore described and shewn on the accom-
panying drawing.
