page_text: LETTERS PATENT to Jolin Octavius Butler, of the Kirkstall Forgo
Company, Leeds, in the County of York, Engineer, for the Inven-
tion of "CERTAIN IMPROVEMENTS IN THE MODE OF SECURING TIRES TO
RAILWAY WHEELS."
Scaled the 7th September 1875, and dated the 2nd April 1875.
PROVISIONAL SPECIFICATION left by the said John Octavius Butler
at the Office of the Commissioners of Patents, with his Petition,
on the 2nd April 1875.
I, JOHN OCTAVIUS BUTLER, of the Kirkstall Forge Company, Leeds,
in the County of York, Engineer, do hereby declare the nature of the
said Invention for "CERTAIN IMPROVEMENTS IN THE MODE OF SECURING TIRES
TO RAILWAY WHEELS," to be as follows:-
:-
In constructing railway wheels it is of the utmost importance that the
tire should be firmly secured to the body of the wheel, and several
Patents have been taken out for effecting this object.
My present Invention consists in certain improvements upon the

page_text: system patented by R C. Mansell on the 1st day of June, 1848, No.
12,170, on the 25th day of April, 1862, No. 1210, and on the 6th day of
November, 1865, No. 2860.
In securing tires to wheels according to R. C. Mansell's Patents the
bolts for holding the annular clip rings are placed either between the
spokes or in the space between the spokes and the tire, consequently
there is a hollow space around part of the bolt, and when the nuts are
tightened up the clip rings are either bent or strained and the bolts arc
liable to work loose. Now my Invention consists in boring a hole
through the rings and through the solid part of the spoke, where it
joins the felloe, or through projections or swells formed on the inside
of the felloe, and as the bolt or screw fits accurately into the holc a
perfectly solid connection is formed, and when the nuts of the bolts are
tightened up the clip rings are kept truc, or when only one clip ring is
used the tire is rolled with a dovetailed annular lip, against which the
felloc of the wheel is tightened by a scrow bolt, which may be rivetted
into the body of the wheel.
Another part of my Invention consists in forming annular projections
or grooves around the felloe of the wheel, and corresponding grooves or
projections on the clip rings, the object of which is to give additional
support to the tire and to relieve the bolt from the strain. Tires thus
secured are safer than those secured as heretoforc.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Octavius Butler in the Great Seal Patent
Office on the 1st October 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
OCTAVIUS BUTLER, of the Kirkstall Forge Company, Leeds, in the
County of York, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of April, in the year of our
Lord One thousand eight hundred and seventy-five, in the thirty-eighth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said John Octavius Butler, ler special licence that

page_text: I, the said John Octavius Butler, my exccutors, administrators, and
assigns, or such others as I, the said John Octavius Butler, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
3 therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ircland, tho
Channel Islands, and Isle of Man, an Invention for "CERTAIN Improve-
MENTS IN THE MODE OF SECURING TIRES TO RAILWAY WHEELS," upon the con-
dition (amongst others) that I, the said John Octavius Butler, my exc-
cutors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months next and immc-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Octavius Butler, do hereby
declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement (that is to say) .-
In constructing railway wheels it is of the utmost importance that
the tire should be firmly secured to the body of the wheel, and several
Patents have been taken out for effecting this object.
My present Invention consists in certain improvements upon the
system patented by Richard Christopher Mansell on the First day of
June, 1848, Number 12,170, on the Twenty-fifth day of April, 1862,
Number 1210, and on the Sixth day of November, 1865, Number 2860.
In securing tires to wheels according to the said Richard Christopher
Mansell's Patents the bolts for holding the annular clip rings (in wheels
with spokes) are placed either between the spokes or in the space
between the spokes and the tire, consequently there is a hollow spaco
around part of the bolt, and when the nuts are tightened up the clip
rings are either bent or strained and the bolts are liable to work loose.
Now my Invention consists in boring the bolt holes through the clip
rings and through the solid part of the spoke where it joins the felloe
or rim, or through projection (or swells formed on the inside of the
felloe or rim, and as the bolts or screws fit accurately into the holes a
perfectly solid connection is formed, and when the nuts of the bolts

page_text: are tightened up the clip rings are kept true, or when only one clip ring
is used the tire is rolled with a dovetailed annular lip, against which the
felloc or rim of the wheel is tightened by a screw bolt, which may be
rivetted into the body of the wheel.
Another part of my Invention consists in forming annular projections
or grooves around the felloc or rim of the wheel and corresponding
grooves or projections on the clip rings, the object of which is to give
additional support to the tire and to relieve the bolts from the strain.
Tires thus secured are safer than those secured as heretoforc.
And in order that my Invention may be fully understood I will
proceed to describe the accompanying two Sheets of Drawings.
On Sheet 1 Fig. 1 is a front view, and Fig. 2 a transverse section
of a railway wheel, the tire of which is secured to the body of the wheel
according to my Invention a is the body of the wheel, consisting of
a-nave,_solid spokes, and the rim or felloc, all of which are forged solid,
b is the tire, which is secured to the rim of the wheel by means of the
retaining ring c and bolts d
The ring c is provided with an annular
projection A, see Fig. 6, fitting into a corresponding groove in the
tire, as described in the Specification of Richard Christopher Mansell's
Patent of the 25th April, 1862, Number 1210, and others, but:
in addition to this annular projection A 1 make another similar pro-
jection B on the ring fitting into a groove in the rim or felloe of the
wheel. The projection B may be made ou the rim or felloe and fit in
a recess in the clip ring. The spokes are rounded off into the rim, as
shown by dotted lines in Fig. 1 of Sheet 1, and in Fig. 11, of Sheet 2, 2
so as to form a solid mass, through which the hole for the bolt dis
bored. The ends of the bolts & arc rivetted over the nuts to prevent
them unscrewing. The tire is provided with a dovetailed annular lip
at one side, as now customary, and the bolts & pass through the ring c,
then through the hole bored through the solid metal of the body of the-a
wheel a, and then though the dovetailed annular lip of the tire b, and
as all the paits of the wheel are accurately fitted together it is evident
that when the nuts of the bolts & are tightened up a perfectly solid con-
nection is formed Instead of making the holes for the bolts & through
the metal forming the junction of the spoke and the im or felloc, as 3
above described, I also propose to make swells or projections on the
inside of the felloc or rim, as shown in dotted lines at e, in Fig 5, Sheet 1,
and to bore the bolt holes through these swells or projections.

page_text: Figs. 3 and 4, Sheet 1, represent an elevation and section of an
ordinary railway wheel with double spokes, commonly called the "Kirtley"
wheel, to which my improvements are applied, in this case the bolts d
pass through the solid metal at the junction of the spokes and the rim
or felloc, as shown best in Fig. 5, and in Fig. 15 of Sheet 2, in other
respects this wheel is similar to that shewn in Figs. 1 and 2.
Figs. 3 and 4, Sheet 1, represent an elevation and section of an
ordinary railway wheel with double spokes, commonly called the "Kirtley"
wheel, to which my improvements are applied, in this case the bolts d
pass through the solid metal at the junction of the spokes and the rim
or felloc, as shown best in Fig. 5, and in Fig. 15 of Sheet 2, in other
respects this wheel is similar to that shewn in Figs. 1 and 2.
Fig 5 is a full size view of part of the tire, rim, and spokes of the
wheel, shewn in Figs. 3 and 4.
Fig. 6 is a full size section of the wheels shown in Figs. 2 and 4.
Fig. 7 is a section of the same wheel, but with the bolt & screwed
into the dovetailed annular lip of the tire, and then rivetted instead of
being provided with a nut, as before described.
Fig. 8 16 a section of a wheel similar to Fig 6, but with the retaming
ring c and the annular projections and grooves A and B placed on the
outside of the wheel instead of inside, as before described.
On Sheet 2 Figs. 9 and 10 represent an elevation and section of a
railway wheel with solid spokes, to which a modification of my Inven-
tion is applied, Figs. 11 and 12 are similar views of the body of the
same wheel, shown detached, in this wheel the tire is secured to the
body by means of two retaining rings c, one placed at each side of the
wheel; the annular projections and recesses A and B are similar to
those before descubed, and the bolts & pass through both the rings c
and solid part of the felloc and are rivetted over the nut. Figs. 13
and 14 are two views of a double spoked or "
Kirtley" wheel, with the
tire secured as above described; and Fig 15 is a detached view of the
body of the wheel; Fig. 16 is a detached view diawn full size of the
wheels shewn in Figs. 9 to 15 inclusive.
•
The application of the annular projection B in addition to Mansell's
projection A is found to add considerably to the security of the wheel,
as in case of the tire breaking the shock of the centrifugal force is taken
off the bolts d, and consequently reduces the danger in case of a fracture
in more than one place.
Having thus stated the nature of my Invention, and described several
modes of performing the same, I wish to remark that I do not limit
myself to the details given, and I declare that I claim,--
First. Securing the tire to the body of the wheel by bolts passing

page_text: through holes bored through the annular lip of the tire, through the
solid metal of the wheel, and through the chip ring, as shewn and
described in reference to Sheet 1.
Secondly. Securing the tire to the body of the wheel by bolts passing
through holes bored through the clip rings and through the solid metal
of the wheel, as shown and described in reference to Sheet 2.
-
And, lastly. The application of the annular projection B on the clip
ring fitting into a recess in the rim or felloe of the wheel, or vice versa,
as shown and described.
In witness whereof, I, the said John Octavius Butler, have hereto 1
set my hand and scal, this Twenty-first day of September, One
thousand eight hundred and seventy-five.
