ARTHUR WATERHOUSE, 15 Hartley Hill, Leeds, Foreman Joiner, do hereby
declare the nature of this invention to be as follows:-
The spindle is square & screwed at the corners. The nut is round & chased
across the edge. The neck of the knob is cast with a square hole in the end, to fit
the spindle, and also a long hole in the top of the neck large enough to admit the
nut to drop in. & screw to the end of the spindle. The rose has the hole large

Improved Method of Attaching Door Knobs to their Spindles.
I, ARTHUR WATERHOUSE, of 15 Hartley Hill, Leeds, in the County of York,
Foreman Joiner, 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:-
The object of this invention, is to so improve the method of attaching door knobs
to their spindles, that they may be readily fitted in position when required, whilst
at the same time they are not liable to come off or work loose when in use.
In order that my invention may be clearly understood, I will proceed to describe
same with reference to the accompanying drawing, in which similar letters refer
to like parts in all the figures.
Figure 1 shews a section of a door with knobs and spindle constructed according
to my invention fitted thereto, and Figures 2 and 3 are detail views.
According to my invention, I employ a rectangular or other non-circular
spindle A having a thread cut on its corners, and the neck B of the knob C is
formed with a rectangular hole in same to take onto the spindle A. D is a slot
or hole in the neck B for the purpose of receiving a nut E, the interior of which
is provided with a screw thread for engaging with the thread on the spindle A.
F is a rose, the interior of which is large enough to permit it to be slipped back
over the exterior of the neck B, as seen in dotted lines at Figure 1. H is the
second knob which is firmly attached to the opposite end of the spindle A, and K
is the rose employed with the second knob.
In applying the knobs and spindle to a door, the rose K is placed on the knob H

page_text: and the latter is placed against the door, the spindle being passed through the door
in the usual way. The rose F is then slipped over the neck B, on which it is
pushed back into the position shewn in dotted lines at Figure 1, and the nut E is
dropped into the recess D in the neck B, as seen best at Figures 2 and 3. By
placing the end of the spindle A in the aperture in the neck B, the end of the said
spindle A is brought against the face of the nut E, when the latter is caused to
engage with the said spindle A, by being turned by means of a bradawl or other
convenient tool. The turning of the nut E has the effect of carrying the neck B
and knob C along the spindle A, until the face of the neck B or its washer comes
against the door. The rose F can now be placed in position against the face of
the door, where it is secured by screws or by other convenient means.
It will be readily seen that by the employment of a spindle and knobs as above
described, the knobs may be adjusted to the greatest nicety, and the accidental
pulling off of the knobs is entirely obviated.
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 employment of a screwed spindle A, in combination with the neck B,
knob C, slot D, and nut E, substantially as and for the purposes set forth.
2. The combination of the spindle A, neck B, knob C, slot D, nut E, and rose F,
substantially as and for the purposes set forth.
3. The general arrangement, construction, and combination of the various parts
forming my improved means of attaching door knobs to their spindles, sub-
stantially as described and illustrated in the accompanying drawing.
