This invention has for object to enable wheels such as described in the specifi-
cations of my former patents N° 399 AD 1876, N° 2727 AD 1878, and N° 434
AD 1881, to better withstand the action of powerful brakes such as are now
commonly used, and which, by producing great friction, have sometimes a tendency
to affect the stability of the wheel by injuring the wooden or other centre or body
thereof, which sometimes is set on fire near its periphery, especially after the tyre
has become somewhat worn.
Now according to my present invention, in order to increase the stability of the
wheel and to retain the tyre in its place notwithstanding injury to the wheel
centre or body, I provide distance pieces stops or abutments between the fastening
rings where two are used one at each side of the wheel, or between the fastening
ring at one side and the disc at the other side of the wheel whether one or two
rings be used. The distance pieces stops or abutments may be formed with the
bolts whereby the tyre and its rings or holding devices are secured in place or may
be made separate therefrom. According to one arrangement the bolts pass through
the distance pieces.

I, WILLIAM HENRY KITSON, of Crooked Acres, Kirkstall, near Leeds, in the
County of York, 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 has for object to enable wheels such as described in the specifi-
cations of my former patents No 399. A.D. 1876. N° 2727. A.D. 1878. and N° 434.
A.D. 1881, to better withstand the action of powerful brakes such as are now
commonly used, and which, by producing great friction, have sometimes a tendency
to affect the stability of the wheel by injuring the wooden or other centre or body
thereof, which sometimes is set on fire near its periphery, especially after the tyre
has become somewhat worn.
Now according to my present invention, in order to increase the stability of the
wheel and to retain the tyre in its place notwithstanding injury to the wheel centre
or body, I provide distance pieces, stops, or abutments between the fastening rings
where two are used one at each side of the wheel, or between the fastening ring at
one side and the disc at the other side of the wheel whether one or two rings be
used. The distance pieces stops or abutments may be formed with the bolts
whereby the tyre and its rings or holding devices are secured in place or may be
made separate therefrom. According to one arrangement the bolts pass through
the distance pieces. And in order that my invention may be fully understood
I append hereto a sheet of drawings illustrating methods of carrying my invention
into practical effect. Fig. 1. shows in cross section half of a wheel in which the
tyre A. is secured in place by two flanged rings B. C. the bolts (of which one is
shown at D.) passing through the two rings and through the disc E; which con-
struction so far is well known. F. is a distance piece in the form of a tube, the
length of which is equal to the thickness of the wheel centre or body G. at the part
through which the said tube extends.. The tube fits accurately in a hole in the
wheel centre or body but is of an internal diameter slightly larger than the external
diameter of the bolt D. which passes through it and which fits accurately the holes
made for it in the two fastening rings B. C. By this construction additional
stability is given to the wheel. Fig. 2. illustrates a modification in which a tubular
distance piece F. is applied between the fastening ring B. at one side and the
disc E. which is flanged and enters a recess in the tyre which in this case is
secured by the disc and one ring. The bolt D. passes freely through the tubular
distance piece F. but fits accurately the holes made for it in the ring B. and disc E.
Fig. 3 shows a modification in which the construction of the wheel resembles that
illustrated in Fig. 2, the tyre A. being secured in place by the ring B. and flanged
disc E, but in this case the distance piece stop or abutment F forms part of the
bolt D which is threaded at each end, and at its intermediate part for a length
equal to the thickness of the centre or body G. is made of a diameter greater than
that of the holes in the ring B. and disc E. through which the reduced ends of the
bolt pass

page_text: As will be evident wheels of various other constructions than those illustrated
by way of examples may be provided with distance pieces stops or abutments such
as described for the purpose set forth.
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 :
In railway wheels the use of distance pieces stops or abutments applied
substantially in the manner described above for the purpose indicated.
