An Improved Method of Attaching the Knobs of Door Handles to
Spindles.
I, GEORGE WOOLLISCROFT, Grange West Kirby in the County of Chester Ironmonger
do hereby declare the nature of this invention to be as follows:-
The principle of my invention is the employment of a hollow metal socket with one
solid end within the knob. This socket is inserted within the knob before the neck
of the knob is put on. The socket has a female screw thread on its inner surface. Its
diameter is larger than that of the orifice of the neck, and the turned screw head,
which terminates the solid end, and is outside the knob is also of somewhat smaller
diameter than the rest of the socket so that the socket is retained within the knob
when the spindle is not within the knob. The neck of the knob has a rectangular
aperture, which is enlarged within to receive the open end of the socket. The spindle
is also rectangular and furnished with a male screw thread. The socket is placed so
that its open end is directed towards the neck, and the turned screw head works on
the exterior of the knob at the other end. The spindle is inserted through the neck of
the knob, and the socket by means of the turned screw head can be made to engage
with the spindle at any convenient distance along the spindle.

page_text: I, GEORGE WOOLLISCROFT, of Grange, West Kirby, in the county of Chester, Iron-
monger, 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 relates to improved means for attaching door knobs or handles to
their spindles, and consists chiefly in the employment of a screw threaded socket
arranged in the handle or knob and adapted to engage with screw threads upon the
spindle, so that when the said socket is rotated the spindle will be more or less drawn
within the socket and thereby decrease the distance between the knobs or handles, or
vice versa.
In the accompanying drawing
Figure 1 shews two door knobs or handles attached to a spindle, one of the said
knobs being constructed according to my invention, so as to render it adjustable, and
shewn in section.
Figure 2 is an end view of the adjustable knob.
Figure 3 is a section on the line x, x, Figure 1, and
Figure 4 is a section on the line y, y Figure 1.
a, b are a pair of door knobs or handles and c is the spindle to which the same are
attached.
d is the neck or cap which is secured to the handle a and provided with a rectangular
hole e through which the spindle passes, so that any motion imparted to the handles
will be communicated to the spindle and thence to the parts of the lock.
f is a socket which is inserted in the knob a and held against longitudinal displace-
ment therein at one end by the neck or cap d and at the other by a portion of the
material of the handle as shewn at g in Figure 1 or by means of a collar h secured to
the handle as indicated by dotted lines in Figures 1 and 2. The said socket is adapted
to be rotated within the handle, and is provided at one end with internal screw
threads i adapted to engage with corresponding screw threads k on the spindle. The
other end of the socket has a projection which extends to the outer surface of the
knob and has a slit m formed therein to receive the end of a screw driver.
It will be obvious that if the socket be turned as herein before described, the screw
threads thereon will act upon the spindle and move the same in one or the other direc-
tion according to the direction in which the socket is turned, thereby correspondingly
increasing or diminishing the distance between the knobs.
As the spindle passes through an aperture of corresponding shape in the cap d the
rotation of the handle has no effect on the socket, the latter being immovable relatively
to the handle except through the medium of the projection 1.

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 I
claim is :-
1. The improved method of securing door knobs or handles to their spindles by
means of an internally screw-threaded socket placed within the handle and engaging
with corresponding screw-threads on the spindle, the said socket being arranged in
such a manner that any longitudinal movement of the same relatively to the knob is
prevented, substantially as described.
2. The improved door handle and spindle constructed substantially as hereinbefore
described with reference to the accompanying drawing.
