Year: 1869

page_text: LETTERS PATENT to William Adams, Civil Engineer, of 21, Carlisle
Terrace, Bow, Middlesex, and William George Beattie,. Civil
Engineer, of Surbiton, Surrey, for the Invention of "IMPROVE-
THE BEARING SPRINGS OF CARRIAGES, TRUCKS, AND ENGINES
PROVISIONAL SPECIFICATION left by the said William Adams and
William George Beattie at the Office of the Commissioners of
Patents, with their Petition, on the 5th February 1869.
WILLIAM ADAMS, Civil Engineer, of 21, Carlisle Termee,
Middlesex, and WILLIAM GEORGE BEATTLE, Civil Engineer, of Surbi
Surrey, do hereby declare the nature of-the-said-Invention for
PROVEMENTS IN THE BEARING SPRINGS OF CARRIAGES, TRUCKS, AND ENGINES
USED ON BAILWAYS AND COMMON ROADS," to be as follows:-

page_text: shocks and vibration in railway and other carriages caused chiefly by
the inequalities of the rail or road over which the wheels of such
carriages pass, which methods may be thus described :-
Method 1st. To some convenient part of the frame or body of the
carriage and at each end of the bearing springs we secure a scroll iron
or hanger having a jaw projecting downwards, with holes or slots formed
in such jaw to receive two revolving trunnions formed on the sides of a
socket tube, through which tube passes a rod secured to the end of the
spring by a suitable jaw and pin. On this rod and bearing against the
end of the socket tube we place a spring of india-rubber or steel, or
other suitable elastic material, such spring being confined at the ends
by two metal plates, and secured by screw nuts or cotters, so as to allow
of adjustment. In this plan the usual spring links may be dispensed
with, owing to the socket tube being free to revolve on the trunnions,
and so able to take an angle to suit the variations in the position of the
bearing springs. The socket tube may be lined with an elastic substance
if desired. Instead of a tube socket formed as above described--the
trunnions may be made a continuous cylinder, with a hole passing
through it to receive the rod which carries the spring.
Method 2nd. To effect the same object we make the scroll iron or
hanger in two parts, one part of which is attached to the body or to the
under frame of carriage, and is formed with a jaw to receive a projection
on the other or loose part of hanger, and through which a pin is passed
to secure the two parts of hanger together, so that the loose part may
have motion on the pin. This pin may be surrounded by a tube of
india-rubber or other suitable elastic material to assist in isolating or
lessening the vibrations. At the lower end of this second or loose part
of hanger the usual socket is formed to receive the adjusting rod, which
adjusting rod is secured to the links suspended from the end of the
spring. The top surface of the loose part of hanger is formed to receive
a spring of india-rubber or steel or other elastic substance, which spring
pressing against the frame of carriage prevents the transmission of
shocks and vibrations to the carriage.
Method 3rd.-In this method we make the hole in the socket tube of
the hanger conical, with the large end towards the spring. We form
the small end of the cone of a spherical form to receive a spherical
surface formed on the spring plate, through which the adjusting rod
attached to the spring or link works, A spring is placed on the rod, and

page_text: confined by another plate at the and secured by nuts "screwed on to
the end of the rod, by. means of which the pressure on the spring. is
Whited: By this means the adjusting rod is enabled to take various
-angles:
One object gained by our Invention is to preserve if desired the means-
in present use of adjusting by screws the rods passing through the
Hangers, so as to keep the axle boxes central in the horn plates; but in
Method No. 2 the spring links may be attached to the hanger in the
usual manner if preferred.
Various plans for using india-rubber and other elastic substances in
connection with steel bearing springs have been proposed and tried, we
do not therefore claim such generally; but what we do claim is, the
mechanism for and modes of using such elastic substances or springs, as
herein described.
The parts of our Invention may be varied to suit particular cases;
and the methods described above may be combined in various manners.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Adams and William George Beattie in
the Great Seal Patent Office on the 4th August 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
ADAMS, Civil Engineer, of 21, Carlisle Terrace, Bow, Middlesex, and
WILLIAM GEORGE BEATTIE, Civil Engineer, of. Surbiton, Surrey, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of February, in the year of
our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said William Adams and William George
Beattie, Her special licence that we, the said William Adams and
William George Beattie, our executors, administrators, and assigns, or
such others as we, the said William Adams and William George Beattie,
our 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 lawfully, might make

page_text: 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 THE BEARING SPRINGS OF CARRIAGES, TRUCKS, AND ENGINES
USED ON RAILWAYS AND COMMON ROADS," upon the condition (amongst
others) that we, the said William Adams and William George Beattie,
our executors or administrators, by an instrument in writing under
our, 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 we, the said William Adams and William
George Beattie, 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:-
Our Invention consists of certain methods of applying india-rubber,
steel, or other suitable elastic substances to assist in absorbing the
shocks and vibrations in railway and other carriages caused chiefly by
the inequalities of the rail or road over which the wheels of such
carriages pass, which methods may be thus described:-
Method 1st. To some convenient part of the frame or body of the
carriage A, see Figs. 1 & 2, and at each end of the bearing spring we
secure a scroll iron or hanger B having a jaw projecting downwards,
with holes or slots formed in such jaw to receive two revolving
trunnions C formed on the sides of a socket tube, through which tube
passes a rod D secured to the end of the spring S by a suitable jaw
and pin.
On this rod and bearing against the end of the socket tube
we place a spring of india-rubber E, or steel, or other suitable elastic
material, such spring being confined at the ends by two metal plates F,
and secured by screw nuts or cotters, so as to allow of adjustment.
this plan the usual spring links may be dispensed with, owing to the
socket tube being free to revolve on the trunnions, and so able to take
any angle to suit the variations in the position of the bearing springs.
The socket tube may be lined with an elastic substance if desired.
Instead of a socket tube formed as above described the trunnions may
be made a continous cylinder, with a hole passing through it to receive
the rod which carries the spring.
In

page_text: Method 2nd. To effect the same object we make the scroll iron or
hanger in two parts, see Fig. 3, one part of which B is attached to the
body or to the under frame A of carriage, and is formed with a jaw to
receive a projection on the other or loose part B¹ of hanger, and through
which a pin is passed to secure the two parts of hanger together, so that
the loose part may have motion on the pin. This pin may be surrounded
by a tube of india-rubber or other suitable elastic material to assist in
isolating or lessening the vibrations. At the lower end of this second
or loose part of hanger the usual socket is formed to receive the
adjusting rod D, which adjusting rod is secured to the links. suspended
from the end of the spring S. The top surface of the loose part of
hanger is formed to receive a spring E of india-rubber or steel or other
elastic substance, which spring pressing against the frame of carriage
prevents the transmission of shocks and vibrations to the carriage.
Method 3rd. In this method, see Fig. 4, we make the hole in the
socket tube of the hanger conical, with the large end towards the
spring S. We form the small end of the cone of a spherical form to
receive a spherical surface formed on the spring plate F, through which
the adjusting rod D attached to the spring or link works. A spring E is
placed on the rod and confined by another plate at the end secured by
nuts screwed into the end of the rod, by means of which the pressure
on the spring is varied. By this means the adjusting rod is enabled to
take various angles.
One object gained by our Invention is to preserve if desired the means
in present use of adjusting the spring S by screw rods passing through
the hangers, so as to keep the axle boxes central in the horn plates; but
in Method 2nd the spring links may be attached to the hanger in the
usual manner if preferred.
Two other methods are shown in Figs. 5 & 5ª, 6 & 6", in which the
supplementary spring E is placed vertical; the parts corresponding to
those described in Figs. 1, 2, 3, & 4 are lettered to correspond. Bither
of the above plans may be used combined with compensating beams or
springs, such as are now used on locomotive engines.
Various plans for using india-rubber and other elastic substances in
connection with steel bearing springs have been proposed and tried, we
do not therefore claim such generally; but what we do claim is, the
mechanism for and modes of using such elastic substances or springs as
herein described,

page_text: The parts of our Invention may be varied to suit particular cases; and
the methods described above may be combined in various manners.
In witness whereof, we, the said William Adams and William
George Beattie, have hereunto set our hand and seals, this
Fourth day of August, in the year of our Lord 1869.
WILLIAM ADAMS.
