PROVISIONAL SPECIFICATION.
Improved Means and Appliances for Securing Knobs and Handles
on Door Spindles.
I, FREDERICK MARSHALL, of 59 Trafalgar Road, Greenwich, Kent, Ironmonger,
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to secure knobs and handles on door spindles in a
novel manner and by a novel appliance fitted loosely within the knob or handle, the
turning of which appliance from the outside enables the knob or handle to be adjusted
to suit any width of door and simultaneously fix the knob or handle in position.
For the purpose of my invention, I form a circular opening in the front of a door
knob or handle and from the shank end I insert a screw ferrule, so that its outer end,
which is of smaller diameter, sits in the circular opening the shoulder retaining it in
position.
I then close up the shank end of the knob or handle to retain the ferrule per-
manently within the handle, the filling in piece being of square shape, or corresponding
with that of the spindle.
The end of the spindle is screw threaded and when the ferrule is turned from the
outside the knob or handle is moved along to the desired position.

COMPLETE SPECIFICATION.
Improved Means and Appliances for Securing Knobs and Handles
on Door Spindles.
I FREDERICK MARSHALL, 59, Trafalgar Road, Greenwich, Kent, Ironmonger 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:—
The object of this invention is to secure knobs and handles on door lock spindles in
a novel manner and by a novel appliance fitted loosely within the knob or handle, the
turning of which appliance from the outside enables the knob or bandle to be adjusted
to suit any width of door and simultaneously fix the knob or handle in position.
For the purpose of my invention I form a circular opening in the front of a door
knob or handle A, as in the annexed drawing, and from the shank end B, 1 insert a
screw ferrule C, so that its outer end which is of smaller diameter, sits in the circular
opening, the shoulder retaining it in position. I then close up the shank end B, of
the knob or handle A, to retain the ferrule C, permanently within the handle A, the
inside of the shank being of square shape or corresponding with that of the
spindle D.
The end of the spindle D is screw threaded and when the ferrule is turned from
the outside the knob or handle A, is moved along to the desired position at which it
becomes fixed, until the ferrule is again turned.
The ferrule C, may have a square opening exposed for a key, or it can be closed,
and a nick be made across it, for movement by a screw driver or other tool.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is
The internally threaded ferrule C loosely fitted between the shank B and the
front A of a door lock handle as and for the purpose described and as shown on the
drawing.
