PROVISIONAL SPECIVICATION.
Improvements in or applicable to Wheels and Axles for Trolleys,
Trams, or other similar Waggons,
THOMAS ROWBOTHAM, of Shaw Villa, Stockport, in the County of Chester,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to the construction of wheels & axles similar in design
to those shewn in my Specification No. 5652 /96; but instead of the conical point
of the spiral spring being made to press against the end of the axle; I dispense
with the conical point, and shorten the spring, which I protect with a cover of
brass, or other suitable material, which I fit tight into the inside of the cap,
so that the spring and button are entirely enclosed within the cap, and there is
no pressure or wear of the axle against the spring.

I, THOMAS ROWBOTHAM, of Shaw Villa, Stockport, in the County of Chester,
Engineer, 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 the construction of wheels and axles similar in design
to those described in the Specification of my Letters Patent No. 5,652. of 1896,
but instead of the conical point of the spiral spring being made to press against
the conical recess at the end of the axle, I dispense with the said conical point
(and consequently with the conical recess in the axle) and I shorten the spring
which I protect by a cover of brass, or other suitable material, which I fit or
drive tight into a recess in the inside of the cap so that the spring and the button
are entirely enclosed within the cap, and there is no pressure or wear against
the spring.
The accompanying drawings illustrate how my invention may be carried into
practical effect.
Fig. is an elevation of a pair of wheels a a on an axle b, the right hand
wheel being drawn in section to shew my improvements, these wheels a a and
axle 6 are similar to those described in the specification before referred to, but
differ slightly therefrom as will be seen on reference to the detached views

page_text: Figs 2, 3, 4 hereafter described and a comparison with Fig. 14, which shews
in section a wheel a* and axle end 6* exactly like those described in the said
specification but with my present improvements applied thereto. Fig. 2ª is a
section through the oil box a¹ taken through the same line X X on Fig. 1 as
Fig. 2 is taken, but looked at in the reverse direction.
Fig. 5 is an enlarged detached view of the cover above named marked c and
the spring d and button e. Fig. 6 shows the same in section and fitted in the
cap f, and Fig. 7 is an inside face view of the said cap f...
On Fig. 1 the end of the spindle is shewn reduced in diameter and screwed,
and it is provided with a loose ring g made with a notch g¹ (see detached view
Fig. 3) which is slipped over a pin b fixed in the end of the spindle (see also
detached view Fig. 4) and is held in place by a nut h screwed on the end of the
spindle as shewn.
On Fig. 1 the wheel a is secured on the end of the spindle 6 in the manner
described in the Specification of the Letters Patent above named.
In both Figs. 1 and 1* the cap f is screwed into the oil box as before, and
the button e is pushed in against the action of the spring d as usual for oiling
the axle, the oil passing through into one of the passages f¹ formed in the cap f
to the oil box a
I prefer to provide notches c¹ in the inner edge of the cover c (see Figs. 5, 6
and 7) to allow oil to escape from the cover c to the passage fl.
It is evident that this cap and cover for the spring button is applicable to
any wheels similarly mounted on their axles.
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 combination of the oil box of a wheel and axle of the kind above referred
to with a cap provided with a cover fixed or driven into the said cap so that
the spring and button are entirely enclosed and the end of the axle does not
touch the spring, substantially as herein before described and illustrated by the
annexed drawings.
