PROVISIONAL SPECIFICATION.
An Improved Method of Attaching Door and other Knobs to Spindles
and the like.
I, ABRAHAM ASHWORTH, of 160, Wellington Road, Eccles, in the County of
Lancaster, Agent, do hereby declare the nature of this invention to be as follows:
I drill the spindle longitudinally for a greater or less distance from each end
with a suitable orifice, and tap it with a suitable screwthread, and after placing
the knob on the spindle, I secure it in place by passing a suitable screw through
the centre or axis of the knob and screwing it into the longitudinal orifice. By
this means the knob is securely attached and its position with respect to the door
can be regulated with the utmost nicety.
An Improved Method of Attaching Door and other Knobs to Spindles
and the like.
I, ABRAHAM ASHWORTH, of 160, Wellington Road, Eccles, in the County of
Lancaster, Agent, 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::
I drill the spindle longitudinally for a greater or less distance from each end,
with a suitable orifice, and tap it with a suitable screwthread, and after placing
the knob on the spindle, I secure it in place by passing a suitable screw through
the centre or axis of the knob and screwing it into the longitudinal orifice. By
this means the knob is securely attached, and its position with respect to the door
can be regulated with the utmost nicety.
In a modification of the foregoing, I form the square spindle with a screw-
thread upon its corners and form the longitudinal orifice, in the screw, which is
passed through the axis of the knob as before described.
In another modification I use both methods, locking the hollow screw, or
socket, by means of a smaller screw passing through the head of the hollow screw
and into the central orifice in the spindle.
Referring to the drawing sent herewith:-
Figs. 1 and 2 show respectively a section and front view of a spindle and door-

page_text: knob fitted with my invention in its simplest form, a indicating the square
spindle with central orifice b into which is screwed central screw c, passing through
and securing knob d.
Figs. 3 and 4 show a similar section and view of a spindle and doorknob fitted
with my invention with the first modification described, a indicating the square
spindle furnished with external screwthread e over which is screwed hollow screw
or socket f, passing through and securing knob d.
Figs. 5 and 6 show a similar section and view of a spindle and doorknob fitted
with my invention, with the second modification described, a indicating the
square spindle furnished with external screw thread e over which is screwed
hollow screw or socket f, (passing through and securing knob d,) which is locked
by means of central screw c screwed into central orifice b. This locking screw c
may or may not be furnished with a reverse thread to the hollow screw.
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. Securing door and other knobs to spindles and the like, by means of a
central screw, or socket, passed through the axis of the knob and screwing into,
or over, the end of the spindle or the like, substantially as described and shown,
herein before and in the accompanying drawing.
2nd. Securing door and other knobs to spindles and the like, by means of a
hollow central screw or socket passed through the axis of the knob and screwing
over the end of the spindle or the like, and locked by a smaller screw passed
through the head of the central screw or socket, and screwed into the spindle or
the like, substantially as described and shown hereinbefore and in the accom-
panying drawing.
