PROVISIONAL SPECIFICATION.
Improvements in the Construction of Knobs or Door Handles and in
Adjusting and Holding them upon the Spindles.
I WILLIAM EDWARD RILEY of 6 Carlyle Avenue Plymouth in the County

the knob is passed over the projecting spindle, and the adjusting screw is driven
over the screwed end of the spindle until the knob is adjusted to the required

COMPLETE SPECIFICATION.
Improvements in the Construction of Knobs or Door Handles and in
Adjusting and Holding them upon the 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 held in its required position on
the spindle by a screwed adjusting socket tapped to screw over the end of the
spindle and passing through the front of the knob or handle.
In applying this invention, I use a square spindle screwed at the ends, and knobs
or handles with plain square holes in the neck thereof for the spindle to take into,
the front of the knob is provided with a hole to allow the screwed socket to pass
over the spindle, which is screwed to receive it, and a sunk recess to accommodate
the head of the said socket.
In adjusting the knobs upon the spindle, the knob or handle on one side may be
fixed, and the spindle passed through any fitting to which it is intended to be
applied, the knob on the other side is passed over the projecting spindle, and the
screwed socket is driven over the screwed end of the spindle until the knob is
adjusted in the required position.
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
screwed socket adjusting the knob in its required position and holding it upon the
■pindle.
Figure 2 shews a plan of the front of the knob with screwed socket (d).
Diurachowe a coction of the screwed socket (dr.

page_text: Figure 4 shews an elevation of the same.
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
material, such as wood, metal, glass, chinaware, or earthenware, the screwed socket
may be made of any suitable material, or combination of materials, and all the
parts may be smaller or larger as required, the knobs or handles may be applied to
any fitting requiring adjustable knobs or handles fixed on spindles or their equiva-
lents, the rose may be of any shape and either a separate piece or secured to the
knob or handle before it is adjusted in position.
The knobs or handles may be ornamented and the screwed socket either fixed in
a recess or made projecting and ornamented.
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
Improvements in the construction of knobs or door handles and holding them
upon spindles by means of a screwed socket passing through the front of the knob
and over the end of the spindle, thus accurately adjusting its position and holding
it upon the spindle so that the strain required to turn the spindle is taken mainly
by the neck of the knob substantially as hereinbefore described and shewn on the
accompanying drawing.
Dated this 10th day of February 1892.

Applicant.
