Improvements in the Manufacture of Stair Rods.
I, ERNEST WALTER DOBBS, c/o Dobbs Brothers, Frederick Street, Dudley
Road, Wolverhampton, Manufacturers' Clerk do hereby declare the nature of this
invention to be as follows:-
Stair rods, in considerable varieties, are now made from various sections of tube,
and the present invention relates principally to the substitution for such tubes of a
rolled or drawn bar of "T" section, the upper surface of which may be varied so
as to give a range of ornamental designs, the under side (or "stalk" of the "T")
being in all cases retained to impart rigidity and stiffness to the rod; the
"T" section, at the same time, furnishing material out of which strong ornamental
ends or terminals can be shaped, thus obviating the necessity for the attachment,
by soldering or otherwise, of such ornamental ends, as is the case in rods made
from tubular sections. The "stalk" may also be further utilized as a means of
affixing the rod to the stairs.
Dated this 28th day of November 1894.
1, ERNEST WALTER DOBBS, c/o Dobbs Brothers, Frederick Street, Dudley
Road, Wolverhampton, Manufacturers' Clerk 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:-
For the various sections of tube heretofore used in the manufacture of stair rods,
I substitute rolled or drawn bars of T-section. The outer surface of the head or
table of the section is the portion of a rod which is exposed to view, and may be of
an ornamental form, such as corrugated or fluted, and the ends are preferably cut
or shaped to an ornamental form in outline. The stalk of the section imparts
great rigidity to the rod, and running along the entire length of the back of the
rod lends also rigid support to the ends of the front. These cuds, being formed of
the solid bar, instead of being formed separately therefrom and then soldered or
otherwise fixed thereto as is usual in the case of tubular rods, are not liable to
become detached, and are made at greatly reduced cost. Slots or other holes may
be formed through the stalk of the T-section, by means of which the bar may be
engaged with suitable hooks, used in lieu of stair eyes.
A stair rod, manufactured according to this invention, is illustrated by
Figures 1, 2 and 3 of the drawings herewith, of which Figure 1 is a front
elevation as seen when the rod is in position with the front, or table of the section,
vertical, Figure 2 a plan of the rod when in such position, and Figure 3 a
transverse section of the rod shewn in position within the stair eye.
In Figures 1 and 2 the rod is shewn as if broken in length, for convenience of
illustration.

page_text: The rod A is formed, as above described, of T-section, having a head or table a
and a stalk b.
The ends e are formed in the same piece of metal as the remainder
of the bar, and are shewn as formed of an ornamental shape. The stalk bis
carried the entire length of the rod and is, preferably, curved or rounded over at
its ends, as shewn by Figure 2. The stair eye B is of the usual character of eyes
used with tubular, or other, rods of triangular section.
In Figure 4, which corresponds to Figure 2, slots d are shewn to be formed
through the stalk of the rod. These slots are to enable the rod to be engaged
with hooks (in lieu of eyes) such as that lettered C illustrated in side elevation by
Figure 5, and in front elevation by Figure 6. Each hook is formed with a
tongue to pass through the corresponding slot d of the rod, and with a key or
locking-piece, pivoted at h, which is turned up into the position indicated by
broken lines, Figure 6, to allow the rod to be engaged with the tongue f, and is then
turned down into the position shewn by fuil lines Figure 5, and chiefly by full lines,
Figure 6, to prevent the rod becoming accidentally disengaged from the tongue.
In Figure 5, the rod is shewn, in section, in position within the hook C, with the
stalk b engaged with the tongue f.
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 manufacture of stair rods of T-section with the ends formed solid with,
that is to say, in the same pieces of metal with, the main portions of the rods,
substantially as described, thus avoiding the necessity, experienced with tubular
stair rods, of forming the ends separately and subsequently fixing them, by
soldering or otherwise, to the main portions of the rods.
2. The manufacture of stair rods of T-section with openings formed through the
stalks to enable the rods to be engaged with stair hooks used in lieu of stair eyes,
substantially as described.
