PROVISIONAL SPECIFICATION.
Improvements in Lock Furniture.
We, GEORGE WILLIAM PARKER, of 20 Iona Place Mount Florida, and JAMES
BUCHANAN and WILLIAM WILSON, of 34 Old Wynd, Glasgow, Manufacturers, do
hereby declare the nature of this invention to be as follows :-
This invention relates to lock furniture and it has for its object to improve the
construction of such furniture.
In carrying out our invention we use any desired form of spindle, and, to secure
the knob to the spindle, we employ a rose or washer which is provided with a
hollow externally screwed projection on the inner side and with a circular rim or
flange on the outer side. The end of the spindle passes through the hollow
projection and rose and enters the knob. The screwed projection of the washer is
screwed tight into the wood of the door and the knob is prevented from coming off
the spindle by turning or spinning over the rim or flange of the rose until it catches
on and firmly holds the neck of the knob. As the washer is firmly screwed into
the door and the knob is secured to the rose it cannot be pulled off.
To facilitate the screwing home of the rose it may be made with a square,
hexagon or other projection or part for the reception of a key, brace, or spanner.
If desired, with some locks, both knobs can be secured to the spindle by means of
roses fitted at each side of the door.
In some cases, and for some locks the end of the spindle may be screwed for the
reception of a nut which holds the spindle in place within the rose. The nut may, to
limit its movement, be so cut out or made as to be caught by a pin or projection on
or in the rose.
If so desired the hollow projection of the rose may be screwed both internally
and externally, the internal screw engaging with the screwed end of the spindle
and the external screw with the wood of the door.
If desired, to prevent the rose unscrewing, it may be pinned to the door by small
screws or nails.
The rose and its screwed collar may be made in separate pieces either cast or
stamped out.

Improvements in Lock Furniture.
We, GEORGE WILLIAM PARKER of 20 Iona Place, Mount Florida and JAMES
BUCHANAN and WILLIAM WILSON of 34 Old Wynd, Glasgow, Manufacturers, 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 relates to lock furniture and it has for its object to improve the

page_text: "
In carrying out our invention we use any desired form of spindle and to secure
the knob to the spindle we employ a rose or washer which is provided with a hollow
and, if desired externally screwed projection, on the inner side and with a circular
rim or flange on the outer side. The end of the spindle passes through the hollow
projection and rose and enters the knob. The screwed projection of the washer is
screwed tight into the wood of the door and the knob is prevented from coming off
the spindle by turning or spinning over the rim or flange of the rose until it catches
on and firmly holds the neck of the knob. As the washer is firmly screwed into
the door and the knob is secured to the rose it cannot be pulled off.
To facilitate the screwing home of the rose it may be made with a square,
hexagon, or other projection or part, for the reception of a key brace, or spanner.
If desired, with some locks, both knobs can be secured to the spindle by
means of roses fitted at each side of the door.
In some cases and for some locks the end of the spindle may be screwed for the
reception of a nut which holds the spindle in place within the rose.
The nut may,
to limit its movement, be so cut out or made as to be caught by a pin or projection
on or in the rose.
If so desired the hollow projection of the rose may be screwed both internally
and externally, the internal screw engaging with the screwed end of the spindle
and the external screw with the wood of the door.
If desired to prevent the rose unscrewing it may be pinned to the door by small
screws or nails.
The rose and its screwed collar may be made in separate pieces either cast or
stamped out.
If desired the furniture may be made in several pieces or sections.
And in order that our said invention may be properly understood we have
hereunto appended an explanatory sheet of drawings, whereon,
Fig. 1 is a side view partly in section showing one method of making the lock
furniture.
Fig. 2 is a cross section on the line - Fig. 1.
Fig. 3 is a side view partly in section showing a slightly modified construction of
the lock furniture.
Fig. 4 is a side view, partly in section, of another slightly modified construction
of the lock furniture.
Referring to the drawings:
1
a is the spindle; b, c the knobs; d is the neck of the knob 6; d¹ is a collar or
bead formed on said neck; e is the rose; is the circular rim or flange of the rose;
e are screw holes made in the rose; f is the internally screwed nut which fits on
the spindle a and holds it in place within the hollow projection of the rose; g is a
flange made on the inner end of the hollow projection i, for the purpose of holding
the nut in place; ; is a projection, which, in Figs. 1 and 2, is shown as cast on
the internal surface of the rose e and in Fig. 4 as cast in one with the nut. f; k is a
groove cut in the nut (Figs. 1 and 2) or in the rose (Fig. 4) for the reception of
the projection j.
•
As will be seen at Figs. 1 and 2 the inner projection of the rose e is threaded
externally so as to be screwed into the wood of the door and the rose is made with
an external nut h to enable it to be readily turned by a key or spanner. The knob
is secured to the rose by means of the rim or flange el which is spun over the collar
or bead d¹. The spindle a is securely held in position by the internal nut f which
turns along with it, when the handle is turned in the lock, and, as a consequence,
the thread of the nut is not worn. The projection causes the nut to turn with the
rose when said rose and the knob are being removed. The groove k permits
the nut turning along with the handle when the latch bolt is being operated.
No screws or nails of any kind are required for fixing, and, as a consequence,
there is no dauger, as with the furniture in general use, of screws dropping out or
becoming loose.
As the furniture is screwed into the door by a key or spanner it can only be

page_text: removed by using such a tool. It cannot be taken off by using a knife or nail as
with some of the present constructions of furniture.
In Fig. 3 the rose is securely fixed to the door by nails or screws inserted through
the holes e. The object of securing the rose in this manner is to prevent it
turning round. The projection i is not, in this case, screwed externally.
In Fig. 4 the rose is made with an internal groove k in which works a projection j
similar to that at Fig. 2, but in this case, as aforesaid, made on the nut f. The
rose is or may be secured to the door by screws or nails as at Fig. 3.
A pin may be inserted in the rose or the nut, as the case may be, in lieu of the
projection j.
If desired the nut f may be allowed to work freely in the rose in this case a hole
may be made in the nut and in the rose, and, when it is desired to remove the
handle, the holes are brought in line and a pin inserted so that the nut will turn
along with the rose.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
consider novel and desire to claim is :-
Lock furniture made, substantially as herein before described and shown, under
modifications, at Figs. 1 to 4 of the drawings annexed.
Dated this 30th day of December 1893.
