page_text: I, GEORGE GYBBON POTTER, of 43 Bridge Street, Walsall, in the County of
Stafford, Solicitor, do hereby declare the nature of iny said invention to..be as
follows:-
T
"
i.
My invention consists in the construction and combination of parts hereinafter
described for attaching door and other knobs or handles to and adjusting them on
their spindles.
I will describe my invention as applied to an ordinary door knob.
The spindle I construct in two parts, longitudinally and when placed together
form a plain square spindle of the ordinary thickness, at one end of each part of
this two part spindle I rough the surface for the purpose of permanently fixing to
the knob. To effect this I lay on the casters mould for producing the neck of the
knob the rough end of this spindle so that the molten metal is poured in it,
surrounds the spindle, and is securely fixed; or I may in some cases prefer to pin
the spindle to the knob, or otherwise fix the same.
It will thus be understood that each part spindle is a fixture to each neck of the
knob, and consequently an aperture in each neck of the knob sufficient for the
other end of each part spindle to pass in. The inner surface of one end of the part
spindle farthest from the knob is provided with cross slots or serrations, parallel to
each other and a longitudinal slot or opening is cut through the whole length of
these cross slots the inner surface of the other part spindle is provided with a
lamina spring fixed to the end and passing into the aperture a required distance,
this spring has the interior end slightly upturnéd. In the application of this
invention to its purpose, each part spindle is passed through the door, and lock,
and into each aperture, the upturned end of the spring engaging in each cross or
serration, until each knob is brought to the desired position, and securely held.
To release the parts or detach from the door, one knob is provided with a sinall
hole directly over the longitudinal slot and over the spring and by passing a pointed
instrument down this said hole the spring is depressed and released from the cross
slots or serrations, and the parts separated.

to and Adjusting them on their Spindles.
I, GEORGE GYBBON POTTER of 43 Bridge Street Walsall in the County of
- Stafford, Solicitor, do hereby declare the nature of my said invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:—
My invention consists in the construction and combination of parts hereinafter
described for attaching door and other knobs or handles to and adjusting them on
their spindles.
f
I will describe my invention as applied to an ordinary door knob.
The spindle I construct in two parts, longitudinally and when placed together form
a plain square spindle of the ordinary thickness. At one end of each part of this two
part spindle I rough the surface for the purpose of permanently fixing to the knob."
To effect this I lay in the casters' mould for producing the neck of the knob the
rough end of 'this spindle so that when the molten metal is poured in it surrounds
the spindle and is securely fixed;-or I may in some cases prefer to pin the spindle
to the knob, or otherwise fix the same.
It will thus be understood that each part spindle is a fixture to each neck of the
knob, and consequently an aperture in each neck of the knob, sufficient for the
other end of each part spindle to pass in. The inner surface of one end of
the part spindle farthest from the knob is provided with cross slots or serrations,
parallel to each other, and a longitudinal slot or opening is cut through the whole
length of these cross slots-the inner surface of the other part spindle is provided
with a lamina spring, fixed to the end and passing into the aperture a required
distance, this spring has the interior end slightly upturned. In the application of
this invention to its purpose each part spindle is passed through the door, and lock,
and into each aperture, the upturned end of the spring engaging in each cross or
serration until each knob is brought to the desired position and securely held.
To release the parts or detach from the door, one knob is provided with a small
hole directly over the longitudinal slot and over the spring and by passing a
pointed instrument down this said hole the spring is depressed and released from
the cross slots or serrations, and the parts separated.
And in order that this my said invention may be more clearly understood I will
now proceed to describe it in connection with the accompanying sheet of drawings.
Fig. 1 is a view in elevation, complete shewing my improvements applied to the
detaching and adjusting door and other knobs or bandles on or to their spindles..
Fig. 2 is a view in elevation shewing the mode of attaching and adjusting door
and other knobs on or to their spindles in connection with an ordinary lock.
Fig. 3 is a sectional view through same, shewing mode of attachment and
adjustment.

Fig. 4 is a view in plan of one part detached and part elevation of the end
of same.
Fig. 5 is a view in plan of the other part detached, and part elevation of spring.
Fig. 6 is an end view in elevation.
The same letters of reference upon the several figures indicate like or corre
sponding parts.

page_text: a is a knob of the ordinary kind a being the one that is fixed to the outside
for street door purposes, each knob being permanently secured to the two part
spindle b and c by means of screws or pins as shewn at d, and leaving an aperture
being one half of the square in the neck of each knob, clearly shewn in Fig. 2, 80
that each part of the spindle will pass in.-f are cross slots or serrations upon the
inner surface at the end of b, and g is the longitudinal slot, h the lamina spring
fixed at the end and upon the inner surface of c, at i with the upturned end j;
the knob a which I describe as the inside knob has a small hole k.
By reference to Fig. 2 it will be seen that each part of the spindle is placed in
the lock and the door and by applying an inward pressure to a and a¹, 6 will pass
into the aperture e of a, and c into the aperture e of a¹, the end of b depressing h
until the collars a' are brought up and against the lock and door; ; of h engaging
in fat that part which makes the whole securely connected as Figs. 1 and 3. At
any time when desirous of detaching or separating the parts a small pointed
instrument is passed down the hole k and slot g and upon the spring h, which
releases it from f.
I do not confine myself to the exact shape, configuration or arrangement of parts
shown on the accompanying sheet of drawings and described in this Specification
as I may vary them to some extent while not departing essentially from the said
invention.
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:
1st. The construction of a two part spindle b and c each part being secured to
cach knob at one end, while the projecting ends of each part pass into the same,
one part of the said spindle b being provided with cross slots or serrations f and c
with the spring h for engaging in f, for adjustment, and by means of which they
are securely connected together, as described in the foregoing Specification and
illustrated by the annexed sheet of drawings.
2nd. The general combination and arrangement of parts the whole forming
Improvements in attaching door and other knobs or handles to and adjusting them
on their spindles.
