ENGINES, AND TO RAILWAY AND OTHER CARRIAGES." -A communication from
abroad by William Hogg Brown, of Erie, Pennsylvania, in the United
States of America, Engineer.

PROVISIONAL SPECIFICATION left by the said Montague Richard Leverson
at the Office of the Commissioners of Patents, with his Petition, on
the 25th July 1860.
I, MONTAGUE RICHARD LEVERSON, of No. 12, Saint Helen's Place, in the
City of London, Solicitor and Patent Agent, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN APPLYING SPRINGS TO LOCOMOTIVE
ENGINES, AND TO RAILWAY AND OTHER CARRIAGES," to be as follows:-
DESCRIPTION OF THE DRAWING.
Figure 1 represents in perspective parts of a railway truck or carriage
having springs applied thereto according to this Invention; Figure 2 re-
presents a longitudinal section through one of the axletree bearings; and
Figure 3 shews a transverse section of one of the axletree bearings, the
arrangement of the parts in this Figure differing from the arrangement shewn
in Figure 2. In each of these Figures the same letters of reference refer to
similar parts.

A represents an ordinary railway truck frame; C, the horns for supporting

attached by bolts; when weight is applied on the frame the horns C forco
down the plate a; the upper plate C resting on the axlebox or bearing B is
retained at a fixed position by the wheels D, consequently the tendency of this
weight is to elongate the leaves or plates E in a vertical direction, and the load
is thus suspended. When the springs are relieved they contract into their
former or normal position. The springs may, however, be entirely above the
axle box or bearing, as seen in Figure 3, with but slight modification of the
connecting parts before described in respect to Figure 2. f is a rod, its lower
end rests on the axle box or bearing B, whilst its upper end supports the
plate "a," to which the upper ends of the springs E are connected, as in
Figure 2. The under plate a rests under the framing A, thus simply reversing
the arrangement of the parts, but leaving the action of the springs the same.
Any number of these leaves or plates can be used in each case, according to
the duty they have to perform. The buffers may be connected to the carriage
frame by like springs, and other carriages may be hung on like arrangements
of springs.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MONTAGUE
RICHARD LEVERSON, of Number 12, Saint Helen's Place, in the City of
London, Solicitor and Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of July, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her

page_text: reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Montague Richard Leverson, Her special licence that I, the said Montague
Richard Leverson, my executors, administrators, and assigns, or such others
as I, the said Montague Richard Leverson, 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 therein expressed, should and law-
fully might make, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN APPLYING SPRINGS TO LOCOMOTIVE ENGINES, AND
TO RAILWAY AND OTHER CARRIAGES," (a communication from abroad by William
Hogg Brown, of Erie, Pennsylvania, in the United States of America,
Engineer,) upon the condition (amongst others) that I, the said Montague
Richard Leverson, my executors 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 immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said Montague Richard Leverson, 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:―
This Invention has for its object improvements in applying springs to
locomotive engines, and to railway and other carriages.
And in order that my Invention may be most fully understood and
readily carried into effect, I will proceed to describe the Drawing hereunto
annexed.
DESCRIPTION OF THE DRAWING.
Fig. 1 represents in perspective parts of a railway truck or carriage having
springs applied thereto according to this Invention; Fig. 2 represents a
longitudinal section through one of the axletree bearings; and Fig. 3 shews
a transverse section of one of the axletree bearings, the arrangement of the
parts in this Figure differing from the arrangement shewn in Fig. 2. In each
of these Figures the same letters of reference refer to similar parts.
A represents an ordinary railway truck frame; C, the horns for supporting
the axle boxes or bearings B, which in turn support the truck frame on
the journals of the wheels D, the said frame being free to rise and fall on the
caid journals in accommodating themselves to the weight thereon: Toto

a transverse section of one of the axletree bearings, the arrangement of the
parts in this Figure differing from the arrangement shewn in Fig. 2. In each

A represents an ordinary railway truck frame; C, the horns for supporting
the axle boxes or bearings B, which in turn support the truck frame on
the journals of the wheels D, the said frame being free to rise and fall on the
seid journale in accommodating themselves to the weight thereen; E, F, are

page_text: curved or semi-cliptic leaves or plates of steel that constitute the springs, two
of these leaves or plates are used to each axle box or bearing; they are
connected to the frame and to the axle box or bearing in the following
manner-a, Fig. 2, is a plate underneath the horns C, to which the lower
ends of the leaves or springs E are connected by bolts, on which the ends
can move in expanding or contracting; and c is another plate above the
axle box or bearing to which the upper ends (d) of said leaves or springs are
similarly attached by bolts. When weight is applied on the frame the horns C
forco down the plate a. The upper plate c resting on the axle box or bearing
B is retained at a fixed position by the wheels D, consequently the tendency
of this weight is to elongate the leaves or plates E in a vertical direction, and
the load is thus suspended. When the springs are relieved they contract into
their former or normal position. The springs may, however, be entirely above
the axle box or bearing, as seen in Fig. 3, with but slight modification of the
connecting parts before described in respect to Fig. 2. f is a rod, its lower
end rests on the axle box or bearing B, whilst its upper end supports the
plate a', to which the upper ends of the springs E are connected as in Fig. 2.
The under plate a rests under the framing A, thus simply reversing the
arrangement of the parts, but leaving the action of the springs the same. Any
number of these leaves or plates can be used in each case according to the
duties they have to perform. The buffers may be connected to the carriage
frame by like springs, and other carriages may be hung on like arrangement
of springs.
Having thus described the nature of the said Invention, and the manner
of performing the same, I would have it understood that I make no claim to
any of the mechanical parts separately; but what I claim is the mode of
combining and applying springs to locomotive engines and railway and other
carriages, as herein described.
In witness whereof, I, the said Montague Richard Leverson, have here-
unto set my hand and seal, this Twenty-fourth day of January, in
the year of our Lord One thousand eight hundred and sixty-one.
