Wholesale Ironmongers Trading as Jelley Son & Jones and JOHN WILLIAM
CUNNINGHAM Manager to the above, do hereby declare the nature of our invention
for IMPROVEMENT IN LOCK FURNITURE to be as follows:-
This invention relates to the Improvement in Lock Furniture "ie" Knobs &
Spindles, used in door locks, for opening & closing doors. In carrying out our
invention, we use a slotted spindle, with a knob fixed one end & to the other we
attach a fastening knob, which is provided with a long slotted neck into which is
fastened a rocking lever with a projection one end corresponding with the slots in
the spindle and on the other end, a raised projection forming a means of fastening
and unfastening same.
The Rocking Lever is actuated on by means of a loose or sliding collar, which
when pushed or pressed forward, presses the projection one end of the rocking
Lever, into the slot or slots, of the spindle, thus securely fastening it, To release
the fastening knob, the loose or sliding collar when pushed or pressed backwards,
comes in contact with the raised projection of the rocking lever, which on passing
over same releases the knob.

page_text: We ROBERT CANNING JONES, trading as Jelley Son & Jones Wholesale Iron-
mongers of 196 Blackfriar's Road, in the County of Surrey and JOHN WILLIAM
CUNNINGHAM Manager to the above do hereby declare the nature of our invention
for "IMPROVEMENTS IN LOCK FURNITURE" 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 improvements in lock furniture that is to say in the
knobs or handles and spindles used in door locks for opening and closing doors.
•
In carrying out our invention we use a slotted spindle having at one end a fixed
knob or handle and at its other end a "fastening" or adjustable knob or handle
formed with a slotted neck in which is hinged a rocking lever having an under
projection or tooth at one end corresponding with the slots of the spindle and its
other end projecting upwards, except when otherwise constrained as hereafter
described.
The rocking lever is actuated by a loose collar which slides on the slotted neck
of the "fastening" knob or handle and when pushed forward presses the under
projection or tooth of the rocking lever into either of the slots on the spindle
thereby securing the "fastening" knob or handle in any required position on the
spindle.
To release the "fastening" knob or handle the sliding collar is pushed backwards
and coming in contact with the upward projecting end of the rocking lever
depresses and passes over the same thereby raising the under projection or tooth
of the rocking lever from the slot of the spindle and releasing the "fastening" knob
or handle.
And in order that our said invention may be well understood we shall now
-proceed particularly to describe the same reference being made to the accompanying
sheet of drawings like letters of reference indicating corresponding parts in all the
figures.
Figure 1 is a sectional longitudinal view of our improved lock furniture with its
parts detached or "unfastened" and Figure 2 a similar view with its parts secured
together or "fastened.".
a represents a door lock spindle to one end of which is fixed the knob or
handle b. For a suitable distance from its other end the spindle a is formed
transversely on one side with a series of slots c-d represents a "fastening" or
adjustable knob or handle formed with a cylindrical neck e which has a longi-
tudinal slot for receiving a rocking lever g hinged at h to the sides of the slot f
The end of this rocking lever g furthest from the "fastening" knob or handle d
projects, when in the position seen in figure 1, above the slotted neck e and is
formed with an under projection or tooth i whilst its other end, when in the
position shew by figure 1, is depressed on a level with the neck e by the circum-
ference of a hole through the middle of a loose collar j which is placed on the
neck e and bears against the shoulder of the "fastening" knob or handle d.
In applying our invention the spindle a being passed through the hole in the
door and lock until its fixed knob or handle b.is against one side of the door or

page_text: lock the slotted end of the spindle a will project more or less from the other side
of the door. The "fastening" knob or handle d (with its part in the position
seen in figure 1) is then passed on to the projecting portion of the spindle a until
the end face of its slotted neck e is against the door lock when the loose collar j
will be pushed forwards along the neck e and in so doing will depress the toothed
end i of the rocking lever g into a corresponding slot of the spindle a at the same
time raising the depressed other end of the rocking lever g into the position seen
in figure 2 and by then screwing the loose collar; to the door the "fastening"
knob or handle & will be effectually secured to the spindle a and cannot work loose
thereon or get away.
To release the " fastening" knob or handle d from the spindle a the loose
collar jis unscrewed from the door and pressed backwards against the shoulder of
the knob or handle d so as to depress the projecting other end of the rocking
lever g and raise its toothed end i out of the slot on the spindle a when the knob
or handle d is free and can be detached from the spindle a as seen in figure 1.
By our invention the utmost nicety of adjustment to different thicknesses of
doors is obtained combined with a tightness of hold which no other lock furniture
has yet possessed and being simple in construction and without screws it is
invaluable.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
<
.
The application and use to door locks of a slotted spindle in combination with a
fastening" or adjustable knob or handle constructed as described and with a loose
collar substantially as and for the purpose herein before described and illustrated
by the accompanying drawing
