Improvements in Door Furniture.
I HENRY TUDOR OWENS, of 12 Bath Street, Birmingham, in the County of
Warwick, Merchant, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the construction and arrangement of parts constituting
loor furniture, and consists of the improvements hereinafter described.
Door knobs are usually attached to a spindle which passes through the door and
lock, and such knobs are generally fixed to the spindle by a small neck screw &c.,
others have a rose attached to the knob, and which rose is then fastened to the
door with small screws. The small neck screw is objectionable, so is the fixing of
the rose to the door with small screws, as in the latter the pull is entirely upon
the small screws and the rose.
Another form of fixing knobs to doors is by using a dovetail collar on spindle,
which collar fits into inner side of the rose, the said rose having a lining of a thin
disc of sheet metal, in which case the pull is upon this small disc of thin metal, and
is very objectionable, through being pulled away in course of time from the body
of the rose, the furniture is then useless. To avoid these defects, I have made this
my invention, which consists as follows:-
The one end of the spindle is made fast in the knob. The other end of the
spindle screwed on its corners or angles for some distance. An adjustable barrel
having an internal screw thread to fit the spindle, and with external collars, is
made to pass on to the said screwed spindle. This said adjustable barrel has also at
its front end, a square recess, to receive a square elongation upon the knob. Upon
the neck of the knob is an external collar, in diameter and thickness, similar to the
first collar upon the aforesaid barrel. At its front part, there is also a square elonga-
tion, which, as before intimated, enters into the square recess in the screwed barrel, until
the collar upon the neck of the knob, abuts against the first collareupon the screwed
barrel, which prevonts the rotation of the barrel.
I now proceed to make the rose as follows:-A barrel is provided in halves,
having internal grooves, which correspond to the collar upon the neck of the knob,
and the collars upon the screwed barrel. A circular rose plate is now provided
having screw down holes formed therein, and having also a central hole into which
the one end of the divided barrel enters.
Upon each half of the divided barrel, is an car or lug, having a screw down hole
therein, which when the barrel parts are in their position in the rose plate coincides
with the two opposite screw down holes in the plate.
Thus in fixing or applying this my improved door furniture:-The spindle having
the fixed knob thereon, is first passed through the door and lock; the adjustable
screwed barrel is then passed on to the screwed spindle up to, and against the door ;
the rose plate is next passed on, and then the knob, the front square end of which
enters the square recess in the screwed barrel. The divided rose barrel is now
passed into position, and the rose barrel and the plate screwed to the door when
the fixing is complete.
One of the important features of this my invention is that the pull of the knob
in opening the door &c., is communicated to the spindle itself, and not to the
screws in the rose, inasmuch as the collar upon the knob, is first pulled against the
inside of the groove in the divided barrel, the said barrel however being checked
by the other side of the said groove being upon the other side of the first collar
upon the screwed barrel, thus transferring the pull direct to the screwed collar and
thence to the spindla

page_text: In some instances instead of making a separate circular plate and a divided
rose barrel, I may form half of the plate upon its each half of the rose barrel,
and in some cases, further hinge or joint such two parts together, so that they
may be passed on to the combined knob and screwed collar clipwise. In some cases
I may make a complete circular rose plate, and two semi rose barrels, and attach
the latter to the plate, by first forming a hinge pin upon the plate, and then forming
binges upon the two semi parts, and securing them to such peg, so that the barrel
may open and close upon the plate aforesaid. In such cases, I form upon the
barrel, at the opposite side to the joint, a lug or ear or ears, having holes therein,
by which they may be screwed to the plate, or to the door. Or, in other cases, I
may take the rose barrel in halves, and further provide upon the circular rose plate,
a cylindrical barrel, which, when the two said halves are passed into their places,
the rose and barrel may he passed externally on to the divided rose barrel, and be
screwed to the door &c.

Improvements in Door Furniture.
I HENRY TUDOR OWENS of 12 Bath Street Birmingham in the County of Warwick
Merchant 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 the construction and sarrangement of parts constituting
door furniture, and consists of the improvements hereinafter described.
Door knobs are usually attached to a spindle which passes through the door and
lock, and such knobs are generally fixed to the spindle by a small neck screw &c.,
others have a rose attached to the knob in which the knob may rotate and, which
rose is then fastened to the door with small screws. The small neck screw is
objectionable, so is the fixing of the rose to the door with small screws, as in the
latter, the pull is entirely upon the small screws, and the rose.
Another form of fixing knobs to doors is, by using a dovetail collar on neck of
knob which collar fits into inner side of the rose, the said rose having a lining of a
thin disc of sheet metal, in which case the pull is upon this small disc of thin metal,
and is very objectionable, through being pulled away in course of time from the body
of the rose, the furnitnre is then useless. To avoid these defects I have made this
my invention.
In order to the better explanation of this my invention 1 have appended hereunto
illustrative sheets of drawings, upon which are figured views and letters of reference,
similar letters referring throughout the several views to the same thing or part; and
in which
Fig. 1 is a general sectional view of this my invention as applied to a mortice lock

Figs. 4, 5 and 6 are detached side and end, and sectional elevations of the screwed
barrel.
Figs. 7 and 8 are front, and sectional elevations of the dividable rose as seen
when closed upon the screwed barrel and neck of knob.

Fig. 10 illustrates the application of this my invention to a brass furniture, and
usually used for doors having an outside lock thereon.
Figs. 11 and 12 are side and end views respectively, of the knob shown in
Fig. 10.

page_text: Figs. 13 and 14 show modified details of the divided barrel and the rose plate.
Fig. 15 is a detached front view of the rose plate, as shown in Figs. 13 and 14.
Fig. 16 is a detached front of the divided barrel, as shown in Figs. 13 and 14.
The one end of the spindle a is made fast in the knob b. The other end of the
spindle is screwed on its corners or angles for some distance. An adjustable barrel e
having an internal, screw thread to fit the spindle a, and with external collars d
and e is made to pass on to the said screwed spindle. This said adjustable barrel
has also at its front end a square recess, to receive a square elongation upon the
knob h. Upon the neck of the knob is an external collar i, in diameter and thick-
ness similar to the first collar e upon the aforesaid barrel c. At its front part is
the square elongation g, which, as before intimated, enters into the square recess
in the screwed barrel c, until the collar i upon the neck of the knob abuts against
the first collar e upon the screwed barrel c, which prevents the rotation of the said
barrel.
jis a divided external grooved barrel, upon which is also formed the rose plate k,
that is, both the barrel and the plate are in halves, as seen in Figs. 7, 8 and 9,
being jointed at 2. Within the barrel part are provided grooves m and n which
correspond to the collar i upon the neck of the knob, and the collars d and e upon
the screwed barrel c. In the plate k, screw down holes o, o, o are provided, by
which the whole may be secured to the door. The holes o¹, o' see Fig. 9, when the
two halves are brought together as seen in Fig. 7, coincide one with the other, the
securing screw passing through both holes. Thus in fixing or applying this my
invention, I should proceed thus:
-
The spindle, having the fixed knob thereon, is first passed through the door
and lock; the adjustable screwed barrel e is then passed on to the screwed spindle
up to and against the door: the knob is then passed into position, the front square
endy of which enters the square recess in the screwed barrel c.
The divided rose
barrel and plate is now passed into position, and the plate is screwed to the door,
when the fixing is complete.
As before intimated, Figs. 10, 11 and 12 are modifications shewing the arrange-
ment as applied to brass furniture, the spindle a being fixed at the one end in the
knob b, while upon the neck of the metal knob ¹ itself, is formed the collar the
screwed barrel c, and plate k, and barrel j, being similar to those already described.
The precise details in construction of the combination of the rose plate and the
divided barrel may be without departing from its nature, as for instance as
seen in Figs. 13, 14, 15 and 16, in which is the divided barrel, which when in
position is covered and secured to the door by means of the undivided circular rose
plate and barrel k¹.
In fixing this modification it will be readily seen that before passing the knob h²
into position, the barrel and plate is first passed over the neck of the knob as seen
in Fig. 14; the screwed barrel c, and divided barrel are then adjusted as before
described when the plate and barrel is then passed on and screwed to the door
as seen in Fig. 13.
peg
In some cases I may make a complete circular rose plate, and two semi-rose
barrels, and attach the latter to the plate, by first forming a hinge pin upon the plate,
and then forming hinges upon the two semi-parts, and securing them to such
so that the barrel may open and close upon the plate aforesaid. In such cases,
form upon the barrel, at the opposite side to the hinge joint, a lug, or car, or ears,
having holes therein, by which they may be screwed to the plate or to the door.
One of the important features of this my invention is that the pull of the knob
in opening the door &c., is communicated to the screw threads upon the spindle
itself, and not to the screws in the plate k, inasmuch as the collar i upon the knob h, h¹,
is first pulled against the inside of the groove n, in the divided barrel j, the pull of
the said barrel however, being checked by the other side of the said groove n
thus trans-
acting upon the other side of the first collar e upon the screwed barrel
ferring the pull direct to the screwed barrel and thence to the spindle a, a¹.
Further. By providing the square recess f in the screwed barrel
and the square
C,

page_text: projection upon the front of the face of the neck of the knob to take thereinto,
there is no possibility of any alteration of the adjusted position of the screwed
barrel &c., and also prevents any motion or friction between the front of the neck
of the knob and the said barrel, or between the barrel and the spindle.
Having now particularly described and ascertained he nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. The combination in door furniture, with the screwed spindle a, screwed
barrel having external collar or collars, and the neck of knob having external
collar, of the grooved dividable barrel and plate substantially as berein
described and illustrated upon the drawings in Figs. 1 to 13 inclusive.
2. In door furniture the combination with the spindle a, dividable barrel j and
the screwed barrel c baving a square recess at its front end, of the square pro-
jection upon the face of the neck of the knob taking thereinto, substantially as
shown and described and for the purposes specified.
3. In door furniture, the combination with the spindle a. barrel, divided
barrel, and knob h, of the rose barrel cover substantially as described and illus-
trated upon the drawings in Figs. 13 to 16 inclusive.
4. The general combination and arrangement of any of the several parts con-
stituting any improvements in door furniture, constructed and operating substantially
as herein described and illustrated upon the drawings.
