PROVISIONAL SPECIFICATION.
Improved Method of Fastening Knobs Used for Latches for Doors
and the like.
WILLIE MIDGLEY, Upper Lane Mill Cleckheaton Yorkshire Machine Maker
do hereby declare the nature of this invention to be as follows :—
I make fast the knob on shaft which works the latch, by a wedge or key;
combined with a screw, connected with the end of the above named shaft (see
drawing).
I make knob A. of any suitable material; and brass bush B. with oblong hole
one side of hole a little taper to fit wedge F. A round hole is also continued
through the knob (shown at C).
The end of shaft D is either drilled up the centre and tapped for screw E. or
made round and screwed for nut, as E' and D'. The shaft D is toothed a short
distance on one side to fit projections on wedge F. and to allow for adjusting
knob.
The knob is placed on shaft with wedge in position the screw inserted at end and.
made fast.

COMPLETE SPECIFICATION.
Improved Method of Fastening Knobs Used for Latches for Doors
and the like.
I WILLIE MIDGLEY of Upper Lane Mill, Cleckheaton in the County of
Yorkshire, Machine Maker, 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 aud by the following statement :—
I make fast the knob on shaft which works the latch by a wedge or key combined
with a screw connected with the end of the above named shaft (see drawing).
It will be seen that my invention relates to the knobs which are commonly used
on latches of doors, and by means of which the hand of a person (grasping the
knob) may operate the latch. It consists of devices by means of which the knobs
are fastened firmly and securely upon the spindle or shaft, the turning of which
operates the latch.
The drawings referred to in this Specification as illustrating my invention are
those left with the Provisional Specification.
Figure 1. comprises a side view and an end view of a knob and a side view and
an end view of a bush according to my invention.
Figure 2. comprises a view of a knob and bush in position as well as elevations
of wedges spindles and male or female screws for fastening.
Figure 3. is a vertical longitudinal section of the whole fixed together, as when
in use, and position on a door.
I make knob A of any suitable material and brass bush B with oblong hole, one
side of such hole being a little taper to fit wedge F. A round hole is also
continued through the knob (shewn at C). The end of the shaft D is either
drilled up
the centre and tapped for screw E or made round and screwed for nut
.

page_text: as E and D. The shaft D is toothed a short distance on one side to fit pro-
jections on wedge F and to allow for adjusting knob. The knob is placed on shaft.
with wedge in position, the screw inserted at end and made fast.
A is a door knob of ordinary or any convenient shape externally and having a
bole C through it which hole is enlarged at the door end to receive the metallic
bush B. Through this bush runs a rectangular hole which fits the spindle or
shaft D or D' on three sides but is enlarged on the other side to admit a wedge F
which, together with the shaft D or D' fills the rectangular hole tightly. That
part of the shaft D or D' which meets the wedge F is toothed or serrated and the
wedge has one or more corresponding teeth or serrations projecting from it
which meet and engage an equal number of the spaces between the serrations ou
shaft D or D'. By adjustment of these the spindle or shaft D or D₁ with its
wedge F can be made to enter as far into the hole in the bush B as is necessary to
secure the correct position of the knob on the spindle or shaft, when it is screwed
up tight by menus of the screw E or E'.
In Figure 2 the spindle or shaft D is shown as having a female screw in its end
in which screws the male screw E, while the spindle or shaft D' shewn in the same
figure has its end formed into a mile screw and on it screws the female screw E' as
shewn in Figure 3.
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 method of fastening door knobs on their spindles by forming one portion
of the spindles with serrntions into which fit one or more projections forined on
wedge in such manner that by means of the longitudinal adjustment of the
wedge, any desired position of the knob upon the spindle may be secured sub-
stantially as described and shewn.
2. The combination of a door knob a metal bush inserted therein a spindle
having a wedge fitting it with serrations, and a screw for tightening and holding
the same together, substantially as described and shewn.
3. The combined door knob and spindle substantially as described and shewn.
