COMPLETE SPECIFICATION.
Improvements in Attaching Door Knobs to Lock Spindles.
I, ARTHUR JOLLIFFE, of 44, Chalcot Crescent, Regents Park Road, in the
County of Middlesex, Joiner, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This invention relates to a novel and simple arrangement for fixing door knobs
or handles to the spindles of mortise, rim and other locks.
In carrying out my invention I form the knob or handle in two parts and the
end of the spindle is cut with a screw thread on which screws a plate or collar,
which is then fixed by a screw or screws to one part of the knob, the other part of
the knob being screwed either onto the collar or plate, the edge of which is screw
threaded for the purpose, or onto the other part of the knob.
In order to enable my invention to be fully understood will describe how it
can be carried into practice by reference to the accompanying drawing, in
which-
Figure 1 is a section illustrating my improved arrangement for attaching a door
knob or handle to a lock spindle.
Figures 2 and 3 are views of the faces of the two parts of the knob.
Similar letters in all the figures indicate similar parts.
a is the rose secured to the door by screws c, c in the usual manner.
d, d' indicate the knob or handle which I form in two parts as shewn; and e is
the spindle which is square in section as usual and on which I cut a screw-
thread is the plate or collar adapted to screw on the spindle e and to be
fixed by means of the screws h, h to the part of the knob or handle. The other
part d' of the knob or handle is made with a female screw-thread to allow of its
being screwed onto the plate or collar y which is cut with a screw-thread for this
purpose. The part d' of the knob is made with a recess to allow of adjustment.
To fix the knob or handle to the spindle, one part d of the knob is placed on the
spindle e and the collar or plate g is then screwed on the spindle until the part d of
D

page_text: the knob is adjusted to the door. The plate or collar is then fixed to the part d of
the knob by the screws h, h and finally the part of the knob is screwed onto the
plate or collar
9.
Although I have shewn the: part of the knob or handle arranged to screw
onto the plate or collarzy it will be obvious that it can be adapted to screw onto
the other part of the handle which it is only necessary to make with a screw-
thread suitable for receiving the said part-d
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 1
claim is :-
:-
1. The herein described means for attaching door knobs or handles to lock
spindles. consisting in forming the. knob or handle in two parts and the. end of the
spindle with a screw-thread on. which screws a plate or collar which is fixed to one
part of the knob by a screw or screws, the other part of the knob being adapted, to
be screwed either onto the plate or collar or onto the other parts of the knob,
substantially as set forth.

2. The improvements in attaching door knobs to lock spindles as hereinbefore
described and illustrated in the accompanying drawing..
