PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Tubular Terminals.
I, ALFRED CLARK HOWELL, of 4, Sandown Grove, Lozells Road, Aston, near
the City of Birmingham, Modeller, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in the manufacture of tubular terminals,
and its object is to form such terminals-which are of a more or less ornamental
character from the material of the tube itself, after the manner hereinafter
described.
My invention applies to tubes of various sectional shapes.
According to my invention, and as applied for instance to a round tube having
an acorn or similar shaped terminal, such as used for instance for stair rods or
the like. I proceed somewhat thus:-The end of the tube is slitted, and with
necessary portions removed leaving a number of projecting prongs or points.
Within the tube I now preferably place a block (usually of iron) having the
contour of the neck &c. of the shape I desire the terminal to take. I now place
the end in suitable press tools by which the projecting cut away parts are
closed down to each other in such a manner as the joint of their coming together
can scarcely if at all be seen, the said tools or similar tools also necking in the
block and thus forming a terminal of any desired shape similar to those now in
use, but made from the metal of the tube itself.
With the variation of the sectional shape of the tube, I accordingly vary the
cutting away or slitting of the parts at the end, as for instance, in the case of a
right angled triangular tube, 1 cut away side parts leaving top and bottom pointed
like ends, which when closed down under the action of the press tools form a curbed
ornamental end. An additional neck like formation may be further formed by
cutting notches upon each side to permit of a depression of metal to form the
neck.
By this arrangement such terminal ends of an ornamental character may be
made solid with the tube and without solder or the like means.

Improvements in the Manufacture of Tubular Terminals.
I, ALFRED CLARK HOWELL, of 4, Sandown Grove, Lozells Road, Aston, near
the City of Birmingham, Modeller, 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 the manufacture of tubular terminals,
and its object is to form such terminals-which are of a more or less ornamental
character from the material of the tube itself, after the manner hereinafter
described.

In order to more particularly describe this my invention, 1
unto an illustrated drawing upon which are figures and numbers of reference,
similar numbers referring throughout the several views to the same thing or
part.
Fig. 1, is a longitudinal sectional view of a tube, showing portions cut away,
and block inserted to position, illustrating the production of an acorn pattern
terminal.
Fig. 2, is a longitudinal sectional view of the tube, with the metal pressed into
form, and Fig. 3, is an exterior view of same.
Fig. 4, is a longitudinal plan view, showing how portions may be cut away
for the production of a spear head or the like pattern.
Fig. 5, is a sectional view of Fig. 4, also showing a suitable block inserted
therein, and Fig. 6, is an exterior view of same in its completed form.
For the purpose of illustrating the adaptability of this my invention, I have
taken two familiar designs of the acorn terminal and the spear head terminal.
According to my invention, and as applied for instance to a round tube having
an acorn or similar shaped terminal, such as used for instance for stair rods or
the like. I proceed somewhat thus:The end of the tube 8, is slitted, and with
necessary portions removed leaving a number of projecting prongs or points 9.
Within the tube I now preferably place a block 10 (usually of iron) having the
contour of the neck &c. of the shape I desire the terminal to take. I now place
the end in suitable press tools by which the projecting cut away parts 9, are
and 3, so that the
closed down to each other in such a manner as seen in Figs.
joint of their coming together can scarcely if at all be seen, the said tools or
similar tools also necking in the block at 11, and thus forming a terminal of
the desired shape similar to those now in use, but made from the metal of the
tube itself.
With the variation of the sectional shape of the tube I accordingly vary the
cutting away or slitting of the parts at the end, as for instance, in the case of a
right angled triangular tube, as shown in Figs. 4, 5 and 6, I cut away side parts
leaving top and bottom pointed like ends 9, which when closed down under the
An additional neck
action of the press tools form a curved ornamental end.
like formation may be further formed by cutting notches 12, upon, each side to
permit of a depression of metal to form the neck 11, upon the block 10".
The design in some cases, as for instance shown in Figs. 4, 5 and 6, may be
such as to not absolutely demand the block 10%, but it is preferred to use it, as
a much better result even in these cases is produced.
By this arrangement such terminal ends of an ornamental character may he
made solid with the tube and without solder or the like means.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. Forming ornamental terminals on the ends of tubes by cutting away certain
portions of same and closing down such shaped parts upon a shaped block in the
manner set forth and shown upon the drawings.
2. Forming ornamental terminals on the ends of tubes by cutting away certain
portions of same and closing down the said ends in press tools, in the manner
set forth.
