THOMAS PALMER Blacksmith 33 Burnt Tree Tipton Staffordshire CHARLES BROOKES,
Joiner 5 Derry Street Brierley Hill Staffordshire We do hereby declare the nature
of this invention to be as follows:-
The improvements made by this invention in the Tram Car Wheels that are in use
at the present time, consists of an extre flange put on to the inside of the present
or ordenary wheel, the wheel by this improvement represents a double wheel, this
inside flange or wheel is the friction wheel which is absolutely to be used for
brakeing, this inner flange or friction wheel I claim to be an improvement on Trai
Car wheels that are in use at the present time, this inside flange can be cast on to the
outside wheel making it one solid wheel, or the friction flange can be made enter-
changeable that is it can be made in two halves with lap joints and put on to the
outside wheel by means of snugs which shall be cast on to the two halves of friction
wheel bolts and nuts the bolts to pass through the holes in the snugs and through the
centre of harms or spokes of the outside wheel and screwed up tight from the outside
face of wheel, the spokes in the outside or ordenary wheel to forme a face on the
inside so as to allow the face of the snugs on the friction wheel to take an even
bearing, this inside flange to be made smaller than the outside wheel to prevent the
inside friction flange comming in contact with the paving, the friction wheel can be
made of Cast Chilled Iron or of Crucible Steel.

page_text: We, THOMAS PALMER, Blacksmith and CHARLES BROOKES Joiner both of 33 Burnt
Tree Tipton in the County of Stafford do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
Our invention has for its object an improved brake Wheel which is more particularly
adapted to Tram Car Wheels and by which we economize the renewing and consequent
expense of the ordinary chilled wheels which from experience in cases where brakes
have to be applied continuously have worn down five eights of an inch in ten
months at which time the chill is worn out or nearly so after which they soon wear
flat on the tread and have then to be renewed.
By our invention the entire brake friction is taken off the ordinary wheel and
placed instead upon a smaller wheel fixed thereto which wheel through being smaller
is elevated above the roadway and is therefor clear of mud and much drier in wet or
slippery weather which enables the brakes to have much more power.
In order that our invention may be clearly understood and more easily carried
into practice we have appended hereunto a sheet of drawings upon which is illustrated
one of our brake wheels applied to an ordinary cast chilled tram car wheel but it may
readily applied to steel wheels the only difference being to form a face in the
spokes for the snugs of the friction or brake wheels.
be as
Figure 1 is an elevation of an ordinary wheel with the friction wheel fixed thereto
complete.
Figure 3 is a side elevation of the same.
Figure 2 is a section on the line Y. Z. the top portion being through the halved joint
of the friction wheel and the bottom through the solid part of same.
Figure 4 is a front elevation of the friction wheel separate from and ready for fixing
to the ordinary wheel.
The friction brake wheel A is made in two halves A¹ and A' as shewn in Figure 4
this being for the purpose of readily fixing the same to the ordinary wheel B of a
tram car without removing the said wheel. Three, four or more snugs a² are
provided around each half of the friction brake wheel and the arms or spokes b¹ of
the ordinary wheel B are made to form a face to allow these snugs to have an
even bearing thereon. Holes a³ are provided in the snugs a² of the friction wheel A.
which together with the corresponding holes 6 in the arms or spokes 6' allow of the
friction wheel being bolted to the outside wheel B by the bolts C which are put through
from the inside of the wheel and secured by the nuts c¹ on the outside, the rim of the
friction wheel being cut away slightly to allow of the heads of these bolts being
flush with the inside of the rim of the friction wheel while at the same time it
prevents the bolts turning while being secured by the nuts c¹ on the outside. The
two halves of the friction wheel are securely bolted together as well as to the wheel
by means of the halved joints a*a* and a a².

page_text: We do not confine ourselves to the particular details as for instance the friction
wheel A may be made in a number of sections or in one complete piece and of the
form to suit any particular brake.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed what we claim is.
The friction brake wheel A secured to the larger wheel B so as to form part
of same and allow of easy renewal substantially as herein set forth and illustrated
on the accompaning drawings.
