wheel, or taking off the old tire and making a ring with a projection and
shrinking the ring on to the old wheel so as to form a sole or inner tire;
into this projection in cach case we turn a recess or groove to form a
clip for the flange side of the tire. On the other or face side of the tire,
we employ a continuous ring with a clip on it, which may be secured by
tap bolts or hammered down. These bolts may be placed at the corners
of each spoke or partly into the rim as desired.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Alexander Jeffreys and Henry Brook
Woodcock in the Great Seal Patent Office on the 1st October

condition (amongst others) that we, the said Edward Alexander Jeffreys
and Henry Brook Woodcock, or one of us, our executors or admini-
strators, by an instrument in writing under our, or one of our, or their,

page_text: or one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the samė was
to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date
3 of the said Letters Patent.
NOW KNOW YE, that we, the said Edward. Alexander Jeffreys and
Henry Brook Woodcock, do hereby declare the nature. of our said
Invention, and in what manner the same is to be performed, to be
particularly described and ascertained-in and by the following statement
thereof, that is to say :-
•
This Invention has for its object the prevention of accidents from the
breakage of railway, wheel tyres, and relates to the employment of a
projection on the rim of a wheel in combination with a continuous
ring on the outer side of a railway wheel, the ring being in one or more
pieces.
The improvements consist, as in the annexed Drawings, in forming a
projection A. on the outer rim B of a new railway wheel, as in Figure 1,
or turning down the old tire in an old railway wheel, as in Figure 2, or
taking off the old tyre and making a ring with a projection and
shrinking the ring on to the old wheel so as to form a sole or inner tyre,
as in Figures 3 and 4; into this outer projection A in each case we turn
a small groove C so as to form a clip for the flange side D of the tire E;
we use a continuous or segmental ring F with clips G, which ring may
be secured by tap bolts H or hammered down. These bolts may be
placed at the corners between the spokes where the glut is welded in or
partly into the rim, as shown in the section, Figures 1 and 2.
In making new wheels it is proposed to roll the spoke iron with a
projection or flange or rib A on one side, as shown at Figure 5. This
flange may be hammered down at each end, as in Figure 6, under the
steam hammer or otherwise, to the proper size of the spokes I, I,
Figure 7, the middle part with the projection or flange to be left of
sufficient length to form the segment of wheel rim; the corners may
then be filled up by welding in a glut in the usual way.
And having now described the nature of our said Invention, and in
-what-manner the same is to be performed, we declare that we claim,“ "the

page_text: employment of a projection on the rim of a railway wheel in com-
bination with a ring in one or more pieces on the outer side of the wheel,
as described and as shewn in the accompanying Drawings.
In witness whereof, we, the said Edward Alexander Jeffreys and
Henry Brook Woodcock, have hereunto set our hands and seals, 5
this Thirtieth day of September, One thousand eight hundred and
seventy-five.
