I EDWARD PHILLIPS the younger of Moseley in the County of Worcester Artist
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
CONNECTING METALLIC TUBES; WHICH IMPROVEMENTS ARE APPLICABLE TO THE
MANUFACTURE OF THE METALLIC FRAMES OF FIRE SCREENS THE HEAD AND
FOOT RAILS OF METALLIC FURNITURE AND OTHER METALLIC FRAMES". to be as
follows:-
My Invention has for its object to effect the secure and ready connection of
metallic tubes in making metallic frames for various purposes and consists in
effecting their connection in the manner herein after described.
For convenience of description I will describe my Invention as applied to the
connecting together of two tubes at right angles to one another the connected
tubes having the figure of the letter T. The end of the tube which abuts against
the cross head of the T and which I will call the vertical tube is made concave so
as to fit against the said cross head. In the top of the vertical tube I fix preferably
by brazing a short plug having at its top a head and between the head and that
part which is brazed in the tube a neck or contracted part. A hole is made on the
underside of the cross head of a size suitable to permit of the passage of the head
on the vertical tube into the said cross head. I take a short piece of tube having
an external diameter equal to the internal diameter of the cross head and in this
short tube I make a longitudinal slot extending preferably along about one half
the said short tube the said slot being of such a width that it can be passed onto
the neck of the plug in the vertical tube.
The parts are put together as follows: The head on the vertical tube being
introduced through the hole in the cross head into the interior of the cross head
the short slotted tube is passed into the cross head in such a position that its slot
is presented to the neck of the plug described. By now forcing the short tube
home by percussion or pressure its slot is made to engage under the head of the

page_text: plug and thereby fix the said plug and with it the tube to which the plug is brazed.
Although I prefer to employ the slotted short tube described yet a slotted semi-
tubular piece may be employed and although I prefer when using a short slotted
tube to make the slot extend along only part of the tube yet it may extend from end
to end of the tube. Where for any reason it is inconvenient or undesirable to fix
the plug in the tube by brazing it may be fixed by screwing riveting or otherwise.
Metallic frames made of tubes connected according to my Invention are very
strong and are not liable to get out of repair.

do hereby declare the nature of my Invention for "IMPROVEMENTS IN CONNECTING
METALLIC TUBES, WHICH IMPROVEMENTS ARE APPLICABLE TO THE MANUFACTURE
OF THE METALLIC FRAMES OF FIRE SCREENS, THE HEAD AND FOOT RAILS OF
METALLIC FURNITURE AND OTHER METALLIC FRAMES and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
"
My Invention has for its object to effect the secure and ready connection of
metallic tubes in making metallic frames for various purposes and consists in
effecting their connection in the manner hereinafter described.
For convenience of description I will describe my Invention as applied to the
connecting together of two tubes at right angles to one another, the connected
tubes having the figure of the letter T. The end of the tube which abuts against
the cross head of the T and which I will call the vertical tube, is made concave so
as to fit against the said cross head. In the top of the vertical tube I fix preferably.
by brazing a short plug having at its top a head and between the head and that
part which is brazed in the tube, a neck or contracted part. A hole is made in the
underside of the cross head of a size suitable to permit of the passage of the head.
on the vertical tube into the said cross head. I take a short piece of tube having.
an external diameter equal to the internal diameter of the cross head and in this
short tube I make a longitudinal slot extending preferably along about one half.
the said short tube, the said slot being of such a width that it can be passed onto.
the neck of the plug in the vertical tube.
The parts are put together as follows. The head on the vertical tube being
introduced through the hole in the cross head into the interior of the cross head,
the short slotted tube is passed into the cross head in such a position that its slot
is presented to the neck of the plug described. By now forcing the short tube.
home by percussion or pressure its slot is made to engage under the head of the
plug and thereby fix the said plug and with it the tube to which the plug
is brazed.

Figure 1 of the accompanying Drawing represents in side elevation a fire screen
the metallic frame of which is made according to my Invention; Figure 2.
represents in elevation and Figures 3 and 4 in vertical section, a portion of the
said frame drawn of the full size, the said Figures 3 and 4 being taken in planes.
at right angles to one another; Figures 5 6, 7, 8 and 9 represent portions of the
tubes and the connections detached.
The same letters indicate the same parts in the several Figures of the Drawing.
a is the horizontal tube of the fire screen frame, the ends of which tube are to
be connected to the vertical tubes b of the frame according to my Invention. The
ends of the horizontal tube a are made concave as represented at ċ Figure 7, to fit
closely against the vertical tube b. In each end of the horizontal tube a I fix by
brazing a short plug d (shown separately in Figure 6) having at one end a head e
with a neck or contracted part d² between it and the plug. The head e of the
plug d, when fixed in its place, projects from the end of the tube a in the manner
represented in Figures 3 and 8. In that part of the. vertical tube b to which the
horizontal tube a is to be attached, a hole f (see Figure 9) is made of a size
suitable for the passage of the head e on the tube a into the interior of the vertical
tube b

page_text: Figure 5 represents in section and elevation the short slotted tube which I use
for connecting the two tubes a, b together. This slotted tube is marked g and the
slot in its upper part is marked h. The slotted tube g has an external diameter
equal to the internal diameter of the vertical tube b and the longitudinal slot h in
the short tube g has a width equal to that of the neck d² of the plug d fixed in the
horizontal tube a.
In connecting the end of the horizontal tube a to the vertical tube b the head e
of the plug is introduced through the hole f in the vertical tube b into the interior
of the said tube b as represented in Figure 3. The short slotted tube g Figure 5 is
next passed into the vertical tube b in such a position that the slot h is presented
to the neck d² of the plug d. By now forcing the short tube g home in the end of
the tube b by percussion or pressure its slot h is made to engage under the head e
of the plug & and thereby fix the said plug and with it the end of the tube a to the
vertical tube b as represented in Figure 3. Each end of the tube a is connected
to the vertical tubes or parts b, b of the fire screen frame in the manner described
and represented.
By this method of connection the frame is without projecting screws or heads
and the base of the vertical tubes b, b are so strengthened that screw threads
can be made in them for securing the feet i, i (Figure 1) of the screen in their
places.
In connecting the tubes of metallic frames and the rails of metallic furniture in
which frames and rails the connected tubes have the general form of the letter T,
the headed plugs d, d², e are fixed in the ends of the vertical tube instead of in the
ends of the horizontal tube as described with respect to the manufacture of the
metallic frame of a fire screen, but the position of the headed plug with respect
to the tube to which it, is to be connected, depends upon the particular kinds
of frames to be manufactured as will be understood by an examination of the
Drawing.
Although I prefer to employ the slotted short tube described and represented yet
a slotted semi-tubular piece may be employed and although I prefer when using a
short slotted tube to make the slot extend along only part of the tube, yet it may
extend from end to end of the tube.
Where for any reason it is inconvenient or undesirable to fix the plug in the
tube by brazing, it may be fixed by screwing, riveting or otherwise.
Metallic frames made of tubes connected according to my Invention are very
strong and are not liable to get out of repair.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is: The improvements in connecting metallic tubes for the manufacture of
the metallic frames of fire screens, the head and foot rails of metallic furniture and
other metallic frames herein before described and illustrated in the accompanying
Drawing; that is to say, fixing in the end of that tube whose end abuts against the
other tube, a headed plug of the kind described, passing the projecting head of the:
plug through a hole into the interior of the last named tube and fixing the two
tubes together by forcing home a short slotted tube or slotted semi-tubular piece
so as to cause its slot to engage with the projecting head of the plug substantially
as described and illustrated.
