PROVISIONAL SPECIFICATION.
Improved Method of Attaching Door Knobs to their Spindles.
I CHARLES JEPSON WHITEHALL of Queen Street Nottingham in the Town
and County of the Town of Nottingham Tobacconist, do hereby declare the nature
of this invention to be as follows:-
My invention consists in the first place in securing or fitting inside the knob a
square metallic tube or socket & about the same length as the knob & made to
slip over the end of the spindle, one side of this socket is recessed or cut away
within (by preference) a quarter of an inch of each end, the end of the spindle is
also cut away or reduced on one side about the same length as the aforesaid socket,
on this reduced part of the spindle is fitted a flat spring about 16 of an inch thick
& about the same width as the spindle. One end of this spring is firmly secured to
the end of the spindle, the other end of the spring rises above the level of the
spindle, so that when the knob is forced on to the spindle, it presses down the
spring, till the recessed part of the socket, before mentioned, comes over the spring,
when the end of the spring rises, into the recess of the socket, and prevents the
knob from being drawn off the spindle.

COMPLETE SPECIFICATION.
Improved Method of Attaching Door Knobs to their Spindles.
I, CHARLES JEPSON WHITEHALL of Queen Street, Nottingham in the Town
and County of the Town of Nottingham Tobacconist, 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:-
My invention consists in the first place in securing (or fitting) inside the knob a
square metallic tube or socket about the same length as the knob, and made to slip
over the end of the spindle, one side of this socket is recessed or cut away within
(by preference) a quarter of an inch of each end; the end of the spindle is also cut
away or reduced on one side about the same length as the aforesaid socket. On
this reduced part of the spindle is fitted a flat spring about one sixteenth of an
inch thick, and about the same width as the spindle. One end of this spring is
firmly secured to the end of the spindle, the other end of the spring rises above the
level of the spindle, so that when the knob is forced on to the spindle, it presses
down the spring, till the recessed part of the socket beforementioned comes over
the spring, when the end of the spring rises into the recess of the socket and
prevents the knob from being drawn off.
In order that the invention may be more readily understood, I will proceed to
describe it in detail with reference to the accompanying drawings forming part of
this Specification.

Fig. (2). Side view of socket showing spring in position.

page_text: It will be seen in Fig. (1), a portion of the spindle is cut away, to receive the
spring or plate (A), one end of which is (by preference) riveted to spindle and
which may be secured to spindle in various ways (or moved by a separate spring).
Referring to Fig. (2), that part of the socket marked (B) is the main stop or
resisting point or flat, which is formed by the recess in the socket as mentioned in
iny Provisional Specification.
It will be seen that if Fig. (1), is forced into the socket in the direction shown,
the part marked B. would gradually press down the spring or plate, untill the end
of the spring passes inside the recess, when the spring would rise level with top of
socket, as shown in Fig. (2), and prevent the socket (which is made fast to the
inside of the knob) from being drawn off.
When it is required to draw off the knob from the spindle, this is done by
pressing down the end of spring through a small opening in the neck of the knob
by a pin, or similar instrument.
I may here state that a substitute for the socket, might be made in the casting in
the neck of the knob, in the form of a projection inside the knob and of the same
material, but I prefer a separate socket, and made of more durable material.
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 :-
(First.) The use or employment, of a spring or plate attached to a spindle for
the purpose substantially as described.
(Second.) The use or employment of the socket substantially as described.
(Third.) The combination of the spindle, spring, and socket substantially as
described or any mere modification thereof.
Dated this 8th day of September 1894.

Queen Street, Nottingham.
