PROVISIONAL SPECIFICATION.
Improvements in Wheels for Railway Vehicles.
We, WILLIAM STROUDLEY, of Brighton, in the County of Sussex, Locomotive and
Carriage Superintendent to the London, Brighton and South Coast Railway Company
Limited, and SAMUEL CARLTON of Swindon, in the County of Wilts, Engineer do
hereby declare the nature of this invention to be as follows:-
In the Specification of the Letters Patent, number 1630, dated 3rd May, 1875,
there is described a way of securing the tyres to the bodies of the wheels of railway
vehicles. Now the present invention has for its object to dispense with or reduce
the hammering of the tyre which is requisite according to the method set forth in
the above mentioned Specification thus obviating the risk of fracture and enabling a
much harder and more durable steel tyre to be employed.
two or
To this end a ledge, shoulder or check is formed on the outside of the inner or
clip ring, near its inner circumference. This inner or clip ring is secured in position
by means of a wedge or Lewis ring, which is sprung in behind it or inserted in
more parts filling the vacant space in the groove formed in the tyre to
receive the clip spring. The wedge or Lewis ring is bevilled or champered for a
portion of its breadth at its inner side, and when in position is laid down by
a hammer, by which its champered side is applied closely to the clip ring, and its
inner edge is made to bear on the ledge, shoulder or check formed on the clip ring.
The Lewis ring is thus prevented from leaving the groove, while at the same time
it secures the clip ring accurately in place, without being made of the taper form
within the groove as heretofore.
This construction gives an additional support or buttress should the tyre break into
short pieces, and prevents the edge of the clip ring from leaving the rim of the
wheel.
Both rings may be made of mild steel, the Lewis ring being somewhat softer than
the clip ring, so that it may be laid down with a hammer into its place. This
hammering will, of itself, stiffen and harden the ring. Thus the flange or clip of
the tyre itself will not require to be struck with a hammer, or if so only very
lightly.

Improvements in Wheels for Railway Vehicles.
We, WILLIAM STROUDLEY, of Brighton, in the County of Sussex, Locomotive
and Carriage Superintendent to the London Brighton and South Coast Railway
Company Limited and SAMUEL CARLTON, of Swindon, in the County of Wilts,
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 :-
In the Specification of the Letters Patent, number 1630 dated 3rd May 1875

vehicles. Now the present invention has for its object to dispense with or reduce.
the hammering of the tyre which is requisite according to the method set forth in
the above mentioned Specification thus obviating the risk of fracture and enabling a
much harder and more durable steel tyre to be employed.
To this end a ledge, shoulder or check is formed on the outside of the inner or
clip ring, near its inner circumference. This inner or clip ring is secured in position

page_text: by means of a wedge or Lewis ring, which is either cut across and sprung in behind
the inner or clip ring or is inserted in two or more parts filling the vacant space in
the groove formed in the tyre to receive the clip ring. The wedge or Lewis ring is
bevilled or champered or bent for a portion of its breadth at its inner side, and when
in position is laid down by a hammer, by which its champered or bent side is applied
closely to the clip ring, and its inner edge is made to surround the ledge, shoulder or
check formed on the clip ring. The Lewis ring is thus prevented from leaving the
groove, while at the same time it secures the clip ring accurately in place, without
being made of the taper form within the groove as heretofore.
This construction gives an additional support or buttress should the tyre break into
short pieces, and prevents the edge of the clip ring from leaving the rim of the
wheel.
Both rings may be made of mild steel, the Lewis ring being somewhat softer
than the clip ring, so that it may be laid down with a hammer into its place. This
hammering will, of itself, stiffen and harden the ring. Thus the flange or clip of
the tyre itself will not require to be struck with a hammer, or if at all, only very
lightly.
There are several ways of getting both the clip ring and the Lewis ring into
position. One way is to make across the ring a cut and to chamfer the ends at each
side of the cut to admit of springing the ring into place-Another and a better way
is to cut out of the ring a piece of sufficient length to allow the remainder to be
sprung into place, the smaller piece being afterwards inserted to complete the ring in
place The ring may however be inserted into position in several pieces.
Referring to the accompanying sheet of drawings:-
Fig. 1 shews in section so much of one form of a wheel body and tyre as is necessary
to illustrate the invention.
Fig. 2 is a similar view to Fig. 1 shewing the Lewis ring as it appears before it is
hammered or laid down on the clip ring, as it is shewn in Fig. 1.
Fig. 3 shews a section of the Lewis ring.
Figs. & 5 are similar views to Figs. 1 & 3 shewing a slightly modified form of
Lewis ring according to this invention.
1 is the wheel rim or body, 2 the tyre, 3 the clip ring, 4 the wedge or Lewis ring.-
The clip ring has on one side two annular lips or lugs 5, 6 the one engaging with
the wheel rim or body and the other with the tyre-At its opposite side it has a
ledge, shoulder or check 7-The upper portion of the clip ring lies within a groove in
the tyre, and is held in place by the wedge or Lewis ring 4, which is inserted into
the groove behind-In Figs. 1 to 3 the wedge ring is shewn chamfered; while in
Fig. 5 it is shewn of parallel thickness, and bent or angled-When the chamfered
ring is put into its place its bevilled part occupies the position shewn in Fig. 2-It is
then laid down into the position shewn in Fig. 1 and securely locks the wheel body
the tyre, and the ring 3 altogether. The bent or angled ring (Fig. 5) is similarly
treated, and takes the form shewn in Fig. 4.
Having thus described and ascertained the nature of the said invention and in what
manner the same is to be performed I declare that what I claim is :-
1. For securing in place the tyre of a railway wheel, a clip ring having on one
side two lips or lugs engaging respectively with the wheel rim or body and with the
tyre and having on the other side a ledge shoulder or check to serve as a key or
support to a wedge or Lewis ring.
2. Securing in place the tyre of a railway wheel by means of a clip ring having a
ledge shoulder or check, in combination with a wedge or Lewis ring which after being
inserted in its proper place is laid down so that it is secured by the said ledge
shoulder or check substantially as described.
