I THOMAS ELLSEY of 32 Great Portland Street in the County of Middlesex Metal
Worker do hereby declare the nature of this invention to be as follows:-
This invention has for its object improvements in the furniture for door locks.
I employ a square spindle with at one end a screw thread cut upon its corners and
at the other end a knob or handle permanently fixed. The other or loose knob or
handle is applied in the following manner :-a rose plate is provided which will screw
on to the spindle from the side of the door which receives the loose knob or handle
it is intended to be screwed along the spindle until the fixed knob or handle at the
other end of the spindle is home to its place and then to be secured to the door by
screws to prevent it turning. This rose plate has upon it a boss which carries the rose.
In the side of the boss there is a dovetail or undercut recess and this receives into it a
corresponding projection upon the knob or handle around the square hole or recess
into which the end of the square spindle is received. In fixing this furniture the
loose knob or handle is put on during the operation of screwing up the rose plate; as
soon as the end of the spindle appears the projection on the knob or handle is inserted
into the recess in the rose plate and then as the rose plate is further screwed up the
loose knob or handle is drawn by it on to the spindle. The form of the projection
upon the knob or handle admits of its turning freely in the rose plate and it turns
the spindle round with it but the knob or handle cannot draw out from the rose plate
in consequence of the undercut form of the recess and the corresponding form of the
projection.
It will thus be seen that very little strain can come upon the screws of the rose
plate for the rose plate is held to the spindle by the screw thread and the knob or
handle is locked or held to the rose plate by the undercut projection and recess.

Improvements relating to Attaching Door Knobs to Spindles.
I, THOMAS ELSLEY of 32 Great Portland Street in the County of Middlesex, Metal
Worker, 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 :-
This invention has for its object improvements in the furniture for door locks.
In
I employ a square spindle with at one end a screw thread cut upon its corners and
at the other end a knob or handle permanently fixed. The other or loose knob or
handle is applied in the following manner :-A rose plate is provided which will screw
on to the spindle from the side of the door which receives the loose knob or handle it
is intended to be screwed along the spindle until the fixed knob or handle at the other
end of the spindle is home to its place and then to be secured to the door by screws
to prevent it turning. This rose plate has upon it a boss which carries the rose.
the side of the boss there is a dovetail or under cut recess and this receives into it a
corresponding projection upon the knob or handle around the square hole or recess
into which the end of the square spindle is received. In fixing this furniture the
loose knob or handle is put on during the operation of screwing up the rose
plate; as soon as the end of the spindle appears the projection on the knob or
handle is inserted into the recess in the rose plate and then as the rose plate is
further screwed up the loose knob or handle is drawn by it on to the spindle.
The form of the projection upon the knob or handle admits of its turning freely
in the rose plate and it turns the spindle round with it but the knob or handle cannot
draw out from the rose plate in consequence of the under cut form of the recess and
the corresponding form of the projection.
It will thus be seen that very little strain can come upon the screws of the rose
plate for the rose plate is held to the spindle by the screw thread and the knob or
handle is locked or held to the rose plate by the under cut projection and recess.
In order that my said invention may be most fully understood and readily carried
into effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation of a pair of door knobs with the spindle and other parts
connected therewith arranged in accordance with my invention.
Figure 2 is a sectional elevation of the same parts.
Figure 3 is an elevation of the movable knob.
Figure 4 is a plan of the rose plate.
Figure 5 is a side view of the same.
Figure 6 is a sectional elevation showing a modification.
Figure 7 is a plan of the rose plate which, in this modification does not require a
separate rose.

page_text: Figure 8 is an elevation of the movable handle.
a is the spindle square in section and having the handle 6 permanently fixed upon
it in any convenient manner. a¹ is a screw thread cut upon the angles of the spindle.
e is the rose plate, it is adapted to be fixed to the door, for which purpose the rim of
the rose plate is perforated with a hole or holes c² to receive screws entering the wood
of the door. A coarse screw thread may also be cut upon the taper boss c¹. The
boss e' is perforated and a screw thread is cut in it corresponding to the thread upon
the spindle, and the spindle screws through the rose plate. c is a boss upon the outer
side of the rose plate which, for ornament, receives a rose d around it, or, as shown in
c4 is
Figure 6, the rose plate may be so formed as not to require an ornamental rose.
an under cut or dove-tail recess in the boss c³. e is the movable knob, it has a square
passage e in it into which the square spindle a enters; the spindle can slide
longitudinally within the knob but the passage fits the spindle, so that, when the knob
is turned, the spindle is obliged to turn with it. e2 is a neck upon the spindle; it is
flanged at its outer end and is adapted to enter the recess c* in the rose plate from
one side and the knob can then be slidden into a central position. When the parts
are put together in the manner already described the end of the spindle enters the
passage el in the knob, it prevents any lateral movement of the knob in the passage c¹
and the knob cannot then be removed from the rose plate but it can turn in the rose
plate and carry the spindle round with it. The spindle operates in the usual manner
upon the bolt in the lock.
In Figures 6 and 7 the dove-tail or under-cut recess c* in the rose plate is of such
a form that the neck of the knob enters it from the front in place of at the side, or
edge; when it has been so entered it is moved to a central position as in the former
case and it is there secured by the spindle entering the passage e¹ as in the
former case.
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 combination of the rose plate, the spindle and the movable knob ; the rose
plate being screwed on to the spindle and fixed to the door, and the knob receiving
the end of the spindle and engaging with the rose plate substantially as described.
2. The combination of the rose plate c with its dove-tail or under cut recess c¹ and
threaded passage at c¹; the spindle a with the screw thread cut on its angles; and the
movable knobe with its passage e and neck e corresponding to and entering the
recess c* in the rose plate substantially as described.
3. The method of attaching door knobs to spindles substantially as described.
