Improvements in Umbrella Runners.
We, ALFRED CECIL WRIGHT and JAMES LESLIE WRIGHT, trading as Wright and
Harrington of 260 Bradford Street Birmingham in the County of Warwick, Manu-
facturers, do hereby declare the nature of this invention to be as follows:-
The object of our invention is to produce an umbrella runner of superior strength
and quality although at a greater expense than accompanies the production of the
ordinary type of runner.
Ordinary runners are manufactured from thin metal by spinning bending flanging
and other processes and one consequence of such modes of manufacture is the undue
lightness and want of durability of the notch ring portion of the runner. As this
portion bears the whole strain of the umbrella ribs, and must support efficiently the
ends of these ribs, while moving, it is desirable that it should be strong and firm.
In carrying our invention into effect instead of forming the runner from thin metal,
we first cast a brass runner with a thickened or moulded lower end, and a heavy
flange to form the notch at its upper end. We also core out a hole in the casting of
suitable dimensions. We then bore out the runner to fit the umbrella stick, and turn
up the exterior to finish the bead and notch, then we perforate the slot in any suitable
manner, and cut the notches. We are thus enabled to produce runners with any
desired weight and strength of bead, and notch, whereby we manufacture runners
greatly superior in smooth working upon the stick of an umbrella cover even after
prolonged wear. In carrying our invention into effect we may vary the proportions
of the bead and notch as well as the length and thickness of the runner without
departing from the essential feature of our invention which essential feature consists
in the construction of umbrella runners by the combined process of casting, boring,
turning and slotting, instead of the processes herebefore used of bending flanging and
spinning. Our runner is thus made out of solid metal and is very much more durable
than previous articles.

Improvements in Umbrella Runners.
We, ALFRED CECIL WRIGHT and JAMES LESLIE WRIGHT, trading as Wright and
Harrington of 260 Bradford Street, Birmingham, in the County of Warwick, Manu-
facturers, 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 :-
The object of our invention is to produce an umbrella runner of superior strength
and quality although at a greater expense than accompanies the production of the
ordinary type of runner.
Ordinary runners are manufactured from thin metal by spinning, bending, flanging
and other processes and one consequence of such modes of manufacture is the undue
lightness and want of durability of the notch ring portion of the runner. As this
portion bears the whole strain of the umbrella ribs, and must support efficiently the
ends of these ribs, while moving, it is desirable that it should be strong and firm.
In carrying our invention into effect instead of forming the runner from thin metal,
we first cast a brass runner with a thickened or moulded lower end, and a heavy flange

dimensions. We then bore out the runner to fit the umbrella stick, and turn up the
exterior to finish the bead and notch, then we perforate the slot in any suitable manner,
and cut the notches. We are thus enabled to produce runners with any desired
weight and strength of bead, and notch, whereby we manufacture runners greatly
superior in smooth working upon the stick of an umbrella cover after prolonged
wear. In carrying our invention into effect we may vary the proportions of the
bead and notch as well as the length and thickness of the runner without departing
from the essential feature of our invention which essential feature consists in the
construction of umbrella runners by the combined process of casting, boring, turning,
and slotting, instead of the processes herebefore used of bending, flanging and spinning.
Our runner is thus made out of solid metal and is very much more durable than
previous articles.
Referring to the drawings ;
Fig. 1 is a section of the brass casting before manipulation.
Fig. 2 is a section after turning, boring, perforating the slot and cutting the
notches.
Fig. 3 is an external elevation of the finished article showing slot, notches and bead
complete; and
Fig. 4 is a plan showing notches.
In the brass casting Fig. 1, A is the notch flange and B the bead, while C is the
cored out hole.
In Fig. 2 the same letters indicate the finished parts.
In Fig. 3 the perforated or milled slot is shown at D.
The casting Fig 1, is first bored out to make the hole C of the necessary dimensions
for the stick the notch flange A, the bead B and the exterior is next turned in the
lathe the notches are then cut and the slot D is milled, machined, or perforated.
This completes the construction of the runner.
The umbrella runners manufactured in the manner we have described are much
more durable and work much more efficiently than those of ordinary manufacture.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
In the manufacture of umbrella runners forming the runners by the processes of
casting and subsequent boring and machining substantially as hereinbefore described.
