SPINDLES to be as follows:-
LIKE
DOOR, CURDUARD, AND
RAVE
THAT
Ordinary door, cupboard, or like knobs frequently get loose and come off their
spindles.
Numerous contrivances more or less complicated and expensive have been devised
to obviate.
My present invention is to provide a secure means of attachment for such knobs
and spindles but which attachment admits of the knob being instantly detached
from its spindle when desired.
In carrying out my invention I attach to the loose knob by screws or otherwise
a plate carrying a boss fitting the spindle. The boss has projecting edges or flanges
on the same.
On the spindle I fit a travelling nut having a recess in a plate on its face to
receive the projecting edges or flanges on the loose knob.
The face of the plate on the travelling nut is formed with its edges turned up or
in such a manner as to receive a top or filling in plate in which is the before
described recess, a space being left between the bottom of the plate forming the
face of the travelling nut and the said top or filling in plate.
In this space I fit a moveable plate having a recess corresponding to that of the
top or filling in plate and having a small projection moving in a slot in the turned
up side of the face plate so that the moveable plate may be turned round. Say the
projecting edges or flanges on the loose knob are square, then the recesses in the
plates on the travelling nut are square also.
Now if both the recesses in the fixed and moveable plates are coincident then
the edges or flanges on the loose knob can be inserted in the same after the nut
is travelled along the spindle till in a position to receive the knob.

page_text: The moveable plate on the travelling nut is then turned round by its small
projection till the edges of its recess overlap the square corners of the edges or
flanges on the loose knob, thus holding the same to the spindle.
I may punch in one side of the loose plate and correspondingly punch one of
the sides of the fixed plates on the travelling nut to more securely bind both together 5
when locked, or adopt other means of keeping the surfaces tight.
To remove the spindle the small projection on the loose plate is forced back till
its recess is coincident with the recess in the fixed plate when the knob can be
removed at once by simply pulling it off.
Instead of square edges or flanges on the knob, and corresponding recesses in the 1
travelling nut and moveable plate, other forms could be used.

page_text: I form slots O in plate K and place screws on pins P passing through the slots
into plates I. J. to guide the movement of plate K. and hold it to the plates I. J.
Suppose the projecting flanges or edges D¹ on the loose knob are square then the
recesses in the plates I. J. K. on the travelling nut G are square also.
Now if both the recesses H in the fixed (I. J.) and moveable (K) plates are
coincident then the edges or flanges D₁ on the loose knob A can be inserted in the
same after the nut G is travelled along the spindle E till in a position to receive
the flanges or edges D¹ on the knob A.
The moveable plate K in the travelling nut G is then turned round by its small
projection L or by its milled edge Q till the edges of its recess H overlap the
square corners of the edges or flanges D' on the loose knob A thus holding the same
to the spindle E. Instead of the spring piece L on the loose plate K. I may punch
in one side of the loose plate K. and correspondingly punch one of the sides of the
fixed plate J. on the travelling nut G to more securely bind both together when
locked, or adopt other means of keeping the surfaces tight.
To remove the spindle E the small projection L or the milled edge Q on the loose
plate K is forced back till the recess in the said plate is coincident with the recess H
in the fixed plate J when the knob A can be removed at once by simply pulling it
off. Instead of square edges or flanges on the knob and corresponding recesses in
the travelling nut and moveable plate other forms could be used.
If desired of course both knobs could be secured in the way herein described, in
place of one (the other being fixed).
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. Attaching door and cupboard and like knobs to their spindles by means
of a boss with projecting edges or flanges on the loose knob fitting a corresponding
recess in the travelling nut on the spindle and locked by a moveable or turning
plate carried by the said travelling nut arranged with a similar recess so as to lock
when turned over the edges or flanges of the said boss on the loose knob
substantially as described.
Second. The combination of the boss D with its flange D¹ carried by the loose
knob A the recessed plates I. J. on the travelling nut G the moveable locking
plate K and the stop L or its equivalent substantially as described.
