Improvements in Joints for Cornice Poles and the like.
We, JOHN EDWARD HARWOOD and JOSEPH SNUGGS, both of 331, Old Street,
London, EC., Brassfounders, do hereby declare the nature of this invention to
be as follows:
-
This invention relates to improvements in joints for cornice poles, portiere
rods and the like, and it is specially designed with the object of allowing the
said poles, rods and the like to be readily adapted to fit bay windows and other
angular positions, and also that the poles or rods can, when desired, be set tightly
in the desired shape, a further improvement is that he joint is so fashioned that
rings or other supports for curtains can slide freely over the joint.
The joint consists of two half balls or semi-spheres connected with their flat
sides held together in the horizontal position by means of a screw, bolt, rivet
or by other simple means, and can be tightened or fixed at will. Each half ball
is provided with a stout screw projecting point outwards from the edge of its
flat side. Onto each of these screws is fitted a concave fronted rose or collar of
about the same diameter as the two half balls when placed together. These roses
are screwed onto the stout screws above named up to the half balls until their
concave fronts fit closely to the central ball formed by the two half balls, the
screws projecting through the roses sufficiently far to allow the sections of the
poles or rods to be screwed onto them and so fixed in position. The stout screws
may be fitted with nuts or washers if desired.
This joint is preferably made of metal throughout, but it can be made of wood
or a combination of metal and wood, or of any other suitable material.
The heads or tops of the two stout screws may form the flat faces of the two
half balls if desired or may be attached thereto.
If preferred wood or other suitable plugs may be fitted to the joint for attaching
the same to the sections of the poles.

page_text: 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 joints for cornice poles, portiere
rods and the like, and it is especially designed with the object of allowing the
said poles, rods and the like to be readily adapted to fit bay windows and other
angular positions, and also that the poles or rods can, when desired, be set tightly
in the desired shape and a further object of the invention is to make a joint in
which the bearing area or surface is larger and stronger than any hitherto made.
The joint is also fastened so that rings or other supports for curtains can slide
freely over the joint.
The joint consists of two half balls or semi-spheres connected with their Hat
sides held together in the horizontal position by means of a screw, bolt, rivet,
pin or other simple means, and can be tightened or fixed at will. Each half ball
is provided with a stout screw or bolt projecting point outwards from the edge
of its flat side. Onto each of these screws is fitted a concave fronted rose or collar
of about the same diameter as the two half balls when placed together. These
roses are screwed onto the stout screws or bolts above named up to the two half
balls until their concave fronts fit closely to the central ball formed by the two
half balls and thus a large bearing area or surface is obtained for the central
ball to fit. The screws projecting through the roses sufficiently far to allow
the sections of the poles or rods to be screwed onto or otherwise attached to them
and so fixed in position.
The stout screws may be fitted with nuts or washers if desired. These joints
may be made of metal, wood or other suitable material or combination of
materials. When made with wood roses or collars, the said roses may be
extended to form plugs to fit hollow tubes forming the cornice or other pole
(Fig. 4) or loose plugs may be attached to the stout screws or bolts. The concave
fronted roses or collars are adjustable in relation to their position with the
central ball formed by the two half balls by turning the roses upon the screws
or bolts or by using the threaded nuts or washers fitting the screws or bolts behind
the roses. The heads or tops of the two stout screws may form the flat faces of
the two half balls if desired, or may be attached thereto.
We will now describe our invention with reference to the accompanying draw-
ings, in which,
Fig. 1 shews a plan view of a cornice pole constructed according to our inven-
tion with four ball joints.
Fig. 2 shews an enlarged elevation of one of the joints of the cornice pole.
Fig. 3 shews perspective views of the parts of the joints detached.
Fig. 4 shews a vertical longitudinal section of Fig. 2 and shewing the roses
or collars fitted with plug ends.
Fig. 5 shews an elevation of a modified form of joint.
Fig. 6 shews a vertical longitudinal section of Fig. 5.
Fig. 7 shews a plan view of one half of the joint shewn in Fig. 5.
Figs. 1, 2, 3 and 4, shew the joint made in wood, and Figs. 5, 6 and 7 shew
it made in metal.
Referring to Figs. 1, 2, 3 and 4.
a a¹ are preferably, solid wooden semi-spheres one of which is provided with a
screwed pin a (Fig. 4) or the like, projecting upwards from its flat side or face,
the end of which engages with the other semi-sphere which is recessed for that
purpose. Or a screw may pass through one of the semi-spheres and screw into
the other semi-sphere as shewn in Fig. 3. b b are screws which extend outwardly
in opposite directions from the semi-spheres a a¹ and are screwed into the ends
of the cornice pole.
The inner ends or shanks of these screws are flattened and provided with eyes
to fit over the centre pin or screw a³, each semisphere being recessed so that the
Hattened part of each screw will lie flush in the flat face of each semi-sphere.
To further secure the screws bb, they are held in place by small screws 6 passing

page_text: through the flattened shanks. When the semi-spheres are fastened together,
a rose or collar c is placed on each of the screws and screwed up to the ball of
the joint. The inner faces of the roses or collars c are specially formed with a
concave face to obtain a large bearing area or surface which adds great strength
to the joint. The ends of the cornice pole d are then screwed up and fastened
to the roses or collars c to complete the joint. In a modification shewn in Fig. 4,
plugs ends c may be attached to the backs of the collars c which fit into the
cornice poles, the latter being made hollow to receive them.
Referring to Figs. 5, 6 and 7, the semi-spheres a a¹ are made hollow and of
thin metal, the two being fastened together by the pin a³, which, as shewn, screws
into one of the plates which extend across the hollow of each semi-sphere.
bb are screws which extend outwardly and in opposite directions from the semi-
spheres a a¹ and are preferably formed solid therewith. The screws 6 61 may
screw into plugs d tightly fixed in the tubular metal cornice poles d³. The
inner end or shank of each of the screws 661 are cut with a fine thread at b³ onto
which is screwed a washer . Between each of the washers and the corre-
sponding semi-sphere is mounted the circular rose or collar c which is made
with a concave face as above described. The inside periphery of each rose c is
secured in any simple way to the metal cornice poles d
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. In a joint for cornice and other poles made with two half balls pivotted or
screwed with their flat sides together, and each provided with a screw or bolt
projecting outwards from the edges of the flat sides, the concave fronted roses or
collars attached to the screws with their concave sides fitting closely to the
central ball formed by the two half balls, said roses or collars being, if desired,
provided with nuts or washers, immediately behind them.
2. In a joint for cornice and other poles as claimed in Claim 1, the combination
of the two half balls with projecting screws, and the concave fronted roses or
collars attached to the screws and fitting closely to the central ball formed by
the two half balls, and the use of threaded nuts or washers behind the caps, if
desired.
