PROVISIONAL SPECIFICATION.
Improvements in Cornice Poles, Picture Rods, and like Articles.
1, CHARLES JAMES HARCOURT, of Atlas Brass Foundry, Moseley Street, in
the City of Birmingham, Brassfounder, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in cornice poles, picture rods, and like
articles, such improvements consisting in the manner in which I secure the knobs,
terminals, or other connections, to the pole or rod, whereby I form a more efficient
attachment than by the methods at present in ordinary use.
In carrying my invention into effect when forming an attachment for the purpose
of securing a brass or other knob or terminal within a tubular pole or picture rod,
I cast or otherwise produce the knob or terminal in the ordinary manner, and
rigidly connect thereto a screwed stud or pin, which projects from the flat or
flanged side of the knob. Within the end of the tube I insert an expansible
ferrule or spring piece, which I preferably stamp or form from sheet steel or other
metal. The body or upper portion of the ferrule or spring piece may be of
varying configuration, but I preferably form it with three wings, so shaped as to
give a conical or inclined interior surface towards its lower or inner end, for the
reception of the conical plug hereinafter described. The lower or inner end of the
ferrule or spring piece has a circular hole within it, tapped or screwed to receive
the end of the stud or pin secured to the knob or terminal as herein before
described.
To secure the knob or terminal within the tubular pole or rod, I insert the
expansible ferrule within the end of the tube, and place within the same a conical
plug of wood or other material, having a central hole formed through it to permit
of the passage of the stud or pin of the knob. 1 then pass the stud through the
plug and screw its end into the tapped hole at the inner end of the ferrule. The
plug is thus forced into the ferrule until the flat face or flange of the knob or
terminal is brought into contact with the end of the tube. During the process of
screwing the knob stud into the ferrule, the plug and the ferrule are drawn
towards each other in opposite directions, with the result that the wings or
expansible body of the ferrule are or is forced outwards by the action of the conical
or inclined surfaces, and pressed or wedged tightly against the sides of the tubes.
In this manner I am enabled to readily and effectually secure the knob or terminal
to the tube.
I employ my improved method of attaching knobs, terminals, or other parts, to
cornice poles, picture rods and like articles, for the purpose of securing the joints
or junction pieces of curved or angle cornice poles, and especially for the system
of jointing for which Letters Patent No. 16838 of 1891 have been granted
to me.
Instead of an expansible terrule I sometimes employ a ring split preferably at
right angles to its diameter, which is sprung into a groove formed in the
circumference of a wood or other plug, the ring being of slightly larger external
diameter than the plug. I screw the stud or pin attached to the knob, or terminal,
tightly into the plug, and both plug and knob, or terminal, are then securely
connected to the tubular pole or rod by the expansive action of the ring.
I do not limit the application of my invention to any particular form of cornice
pole, picture rod, or like article, or to any one type of knob, terminal, or other

conditions.

Improvements in Cornice Poles, Picture Rods, and like Articles.
I, CHARLES JAMES HARCOURT, of Atlas Brass Foundry, Moseley Street,
in the City of Birmingham, Brassfounder, 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 improvements in cornice poles, picture rods, and like
articles, such improvements consisting in the manner in which I secure the knobs,
terminals, or other connections to the pole or rod, whereby I form a more efficient
attachment than by the methods at present in ordinary use.
be hereinafter
Figure 1 illustrates the application of my invention to the purpose of securing a
knob or terminal to a tubular pole or rod.
In the accompanying sheet of explanatory drawings to
referred to
Figures 2 and 3 illustrate to a larger scale the expanding ferrule or spring
piece.
Figure 4 illustrates the application of my method of attachment to poles or rods
having jointing fittings made in accordance with the Specification No. 16838
of 1891 on which Letters Patent have been granted to me.
In carrying my invention into effect when forming an attachment for the purpose
of securing a brass or other knob or terminal within a tubular pole or picture rod,
I cast or otherwise produce the knob or terminal A in the ordinary manner, and
rigidly connect thereto a screwed stud or pin A' which projects from the flat or
flanged side of the knob. Within the end of the tube I insert an expansible
ferrule or spring piece B which I preferably stamp or form from sheet steel or
other metal. The body or upper portion of the ferrule or spring piece may be of
varying configuration, but I preferably form it with two or more wings so shaped
in the manner illustrated at Figures 2 and 3 as to give a conical or inclined
interior surface, for the reception of the conical plug hereinafter described. The
lower or inner end of the ferrule or spring piece has a circular hole within it
tapped or screwed to receive the end of the stud or pin secured to the knob or
terminal, or an independent nut such as B Figures 2 and 3 attached thereto.
To secure the knob or terminal within the tubular pole or rod, I insert the
expansible ferrule within the end of the tube, and place within the same a conical
plug C of wood or other material, having a central hole formed through it to
permit of the passage of the stud or pin of the knob. 1 then pass the stud A'
through the plug and screw its end into the tapped hole or nut at the inner end of
the ferrule. The plug is thus forced into the ferrule until the flat face or flange of
the knob or terminal is brought into contact with the end of the tube. During the
process of screwing the knob stud into the ferrule, the plug and the ferrule are
drawn towards each other in opposite directions, with the result that the wings or
expansible body of the ferrule are or is forced outwards by the action of the conical
or inclined surfaces, and pressed or wedged tightly against the sides of the tubes.
In this manner I am enabled to readily and effectually secure the knob or terminal
to the tube.

page_text: Instead of placing the expansible ferrule within the tube and afterwards screwing
the stud into the terminal nut or tapped end, I sometimes place the plug C upon
the stud A' and screw on the ferrule before insertion within the tube. The
complete attachment is then inserted within the tube and by turning the latter the
ferrule having its spring ends in contact with the internal surface of the tube, is
screwed up and expanded against the tube, the terminal flanges being at the same
time drawn tightly against the end of the tube and thus secured.
I employ my improved method of attaching knobs, terminals, or other parts to
cornice poles, picture rods and like articles, for the purpose of securing the joints
or junction pieces of curved or angle cornice poles, and I especially adapt it in the
manner as illustrated in Figure 4 of the accompanying drawings for the system of
jointing for which Letters Patent No. 16838 of 1891 have been granted to me.
Instead of an expansible ferrule I sometimes employ a ring split preferably at
right angles to its diameter, which is sprung into a groove formed in the circum-
ference of a wood or other plug, the ring being of slightly larger external diameter
than the plug. I screw the stud or pin attached to the knob or terminal tightly
into the plug, and both plug and knob or terminal are then securely connected to
the tubular pole or rod by the expansive action of the ring.
I do not limit the application of my invention to any particular form of cornice
pole, picture rod, or like article, or to any one type of knob, terminal, or other
connection, but modify these and other details to suit varying requirements or
conditions.
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 method of securing knobs, terminals, or other connections to cornice poles'
picture rods, and like articles, substantially as hereinbefore described.
2. In attachments for securing knobs, terminals, or other connections to tubular
cornice poles, picture rods, and like articles, the use of an expansible ferrule or
spring piece arranged to be forced or wedged against the internal surface of
the tube, substantially as herein before described and as illustrated in the
accompanying drawings.
3. In cornice poles, picture rods, and like articles, the combination and
arrangement upon a projecting screw stud or pin from the knob, terminal, or other
connection, of an expansible ferrule or spring piece with a conical plug or wedge
substantially as and for the purposes herein before described and as illustrated in
the accompanying drawings.
