PROVISIONAL SPLETUATION,
A New Method of Making Stair Rod Ends or Knobs.
THOMAS ROBERT WRIGHT, GEORGE JONES, SAMUEL ROBINSON and
SAMUEL DUNN (trading as T. R. Wright and Company) of 7 Caroline Street
Birmingham, Stair Rod Manufacturers do hereby declare the nature of this
invention to be as follows:-
We turn the ends or knobs from pieces of solid brass wire of proper size, to the
required shape or design, in a lathe, boring them out for fixing on the rods, either
screwing them inside, or leaving the hole plain, and of a shape suitable for
knocking-on" with a hollow punch.

A New Method of making Star O RECK.
We THOMAS ROBERT WRIGHT GEORGE JONES, SAMUEL ROBINSON and
SAMUEL DUNN all of Caroline Street in the City of Birmingham Manufacturers
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 :--
Our invention has for its object a new method of making stair rod ends, tips or
knobs and is applicable to other kinds of rods by which we considerably simplify
and lessen the cost of manufacture of such ends tips or knobs and at the same time
without in any way deteriorating the quality or finish in fact by our said improve-
ment an article of superior finish is produced. Heretofore such ends tips or knobs
have usually been made of cast brass drilled and tapped inside to screw on to the
end of the rod and turned in a lathe to the shape required externally, or, they
have been raised or stamped in dies in a press or stamp approximately to the form
required externally and either screwed inside for screwing on to the end of rod or
left plain for "knocking on the end of rod.
وو
In order that our invention may be clearly understood and more easily carried
into practice we have appended hereunto a sheet of drawings upon which we have
fully illustrated the nature of our said improvements as well as the mode of carrying
the same into effect.
Figure 1 is a view of the wire or rod from which our ends, tips or knobs are
formed.
Figure 2 is a similar view shewing the first stage of manufacture.
Figure 3 is a view shewing the end or knob cut off from the end.
Figure 4 is a longitudinal section through the same after being drilled.
Figure 5 is a similar section to Figure 4 but shewing it with a taper bore at the

page_text: Figure 6 is a view of the end of the stair or other rod.
Figure 7 is the same as Figure 5 but shewn ready for "knocking on."
Figure 8 is a longitudinal section through the rod and knob or end after being
"knocked on "
and pressed.
Figure 9 is a section shewing a modification in the outer form of the knob.
Figure 10 is a section shewing a modification in the mode of attaching
the knob.
Figure 11 is a view of Figure 9 when attached complete.
In carrying our invention into effect we form our ends, knobs or tips A from the
solid length of rod or wire A' Figure 1 by causing it to revolve in any suitable
lathe while a turning tool shaped to the design required is brought to bear upon it
shaping it into the form shown by Figure 2 after which it is cut off in the form
shewn by Figure 3. This knob A is then caused to revolve in the lathe so as to
be drilled or bored as shewn by a² Figure 4 as also with the taper or bell mouth a³
as shewn by Figure 5 which is provided for the purpose of allowing the knob or its
equivalent to be "knocked on to the rod B which is provided with the wedge
head b¹ to receive the bell mouth a' after which the part a' is pressed or punched
into the neck bs by which means the knob, end or tip is retained firmly in position
as shewn by Figure 8. We do not confine ourselves to the exact mode of securing
the ends on as we may screw them on as shewn by Figure 10 in which the screw
nose enters the tapped hole a³.
"
The outward configuration or design of the end knob or tip may be varied to any
extent without departing from the nature of our said invention.
We may reverse the order herein before described by first drilling and then
turning the knobs.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to he performed we declare that what we
claim is :-
The manufacture of rod ends knobs or tips A from a length of rod or wire A¹
substantially as and for the purpose herein set forth and described.
