Year: 1877

page_text: LETTERS PATENT to William Atherton, of Warrington, in the County of
Lancaster, for the Invention of "IMPROVEMENTS IN AND RELATING TO RAILWAY
WHEELS AND TYRES."
Sealed the 3rd July 1877, and dated the 6th January 1877.
PROVISIONAL SPECIFICATION left by the said William Atherton at the
Office of the Commissioners of Patents on the 6th January 1877.

IMPROVE-
This Invention has for its object the construction of railway wheels and the
securely fastening on of their tyres without the use of bolts, set pins, or rivets. It
consists First, in forming the tyre with an inner grooved flange on one side and
turning out a portion from the rim in iron wheels to fit the projecting ring beyond
the turned groove. The other side of the tyre has a spiral groove or thread turned
out and a double tongued flange or ring having a screw thread that fits the spiral
groove, the outer tongue fitting the groove in tyre and the inner one fitting the
groove in rim of the wheel centre, and the flange is screwed up till it clasps the rim
(or the spokes, as the case may be) tightly. Similarly, more especially in wooden
spoked wheels, I construct the boss with a broad iron flange, on one side having a
circular moulding to fit into a groove cut in the spokes, on the other side I cut a
thread on the boss and screw a similar but loose flange with similar moulding tight
up till it holds the spokes as in a vice. By putting on the screwed flanges with an
oxydizing solution such as water, or sal ammoniac and water, the screwed flange is
rusted solidly to the tyre or hub, as the case may be, or the thread can be hammered
up at the outside so as to lock it.

page_text: This Invention has for its object the construction of railway wheels and the
securely fastening on of their tyres without the use of bolts, set pins, or
rivets. It consists, first, in forming the tyre with an inner grooved flange on one
side and turning out a portion from the rim in iron wheels to fit the projecting ring
beyond the turned groove. The other side of the tyre has a spiral groove or thread
turned out and a double tongued flange or ring having a screw thread that fits the
spiral groove, the outer tongue of the flange fitting the groove in the tyre and the
inner one fitting the groove in the rim of the wheel centre; the flange is screwed up
till it clasps the rim (or the spokes, as the case may be) tightly. Similarly in
wooden spoked wheels I construct the boss with a broad iron flange on one side
having a circular moulding to fit into a groove cut in the spokes; on the other side
I cut a thread on the boss and screw a similar but loose flange with similar mould-
ing tight up till it holds the spokes as in a vice. By putting on the screwed flanges
with an oxydizing solution such as water, or sal ammoniac and water, the screwed
flange is rusted solidly to the tyre or hub, as the case may be, or the thread can be
hammered up at the outside so as to lock it.
In order more thoroughly to set forth and explain my Invention I have added
the accompanying Drawings to this specification.
In these Figure 1 represents a half elevation; Figure 2, a section of wheel; and
Figure 3, a full sized section of tyre and rim of wheel with ordinary wrought or
cast-iron boss; Figures 4 and 5, views corresponding to Figures 1 and 2 of a
wooden spoked wheel with my improved hub; Figure 6, a variation, where for ease
in manufacturing the tyre both flanges are screwed on.
In these A is the tyre with flange B, in which is turned groove C to fit the
tongue C of rim of wheel; D, rim carrying tongues C', E'; F, loose flange screwed
on to the tyre at G and firmly gripping the rim D by means of tongue E¹ fitting into
groove E when the flange F is tightly screwed up, gripping also the tyre A by
means of a tongue and groove P, P¹; H, H, spokes. In Figures 4 and 5, I is the
hub, which if of cast iron I prefer to make with one solid flange J armed with
tongue K¹ fitting into groove K in wooden spokes; also loose flange L with tongue M¹
fitting into groove M in spokes, flange L and hub I being cut with a screw thread
at N. By screwing up the flange L till it tightly grips 'the spokes the latter are
held tight as in a vice.
Having now described my Invention, and the best mode known to me of
carrying it into effect, I wish it to be understood that what I believe to be
new and desire to protect under the herein-before in part recited Letters Patent
is,―
1st. The mode of fastening tyres on to railway wheels herein described by
making two flanges on the tyre firmly grip the rim or spokes of the wheel,
one at least of these flanges being in a separate piece from the tyre when first put
together, but locked to it by means of a screw thread or its mechanical equivalent
cut or otherwise placed on the tyre and flange respectively.
2nd. The combination of tyre A, flange B, and tongue and grooves C, C², E, E¹,
for the purposes described.
$
3rd. The combined arrangement of parts of railway wheel, substantially as
shown and described.
In witness whereof, I, the said William Atherton, have hereunto set my hand
and seal, this Twenty-ninth day of June, in the year of our Lord One
thousand eight hundred and seventy-seven.
