page_text: LETTERS PATENT to George Spencer, Civil Engineer, of 77, Cannon
Street, London, for the Invention of "IMPROVEMENTS IN BEARING
SPRINGS TO BE USED FOR RAILWAY, TRAMWAY, AND COMMON ROAD Loco-
MOTIVES. CARRIAGES. AND TRUCKS."
Sealed the 21st September 1875, and dated the 4th June 1875.
PROVISIONAL SPECIFICATION left by the said George Spencer at the
Office of the Commissioners of Patents, with his Petition, on the
4th June 1875.
I, GEORGE SPENCER, Civil Engineer, of 77, Cannon Street, London,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN BEARING SPRINGS TO BE USED FOR RAILWAY, TRAMWAY, AND COMMON ROAD
LOCOMOTIVES, CARRIAGES, AND TRUCKS," to be as follows:-
My improvements in bearing springs to be used for railway, tram-
way, and common road locomotives, carriages, and trucks, consist of
mechanical arrangements of such springs so contrived that the pressure
of the load on such springs acts either horizonally or obliquely instead
of acting vertically like those in common use.

page_text: In the Drawing annexed two plans are shown, one (No. 1) acting
horizontally, the other (No. 2) acting obliquely.
In both plans A, A, is the frame of the carriage; B is the axle box;
C is the spring, shown as made of india-rubber or the compounds known
as such; but springs made of any suitable material or materials and
form may be used.
I am aware that plans for using bearing springs, both horizontally and
obliquely, have been proposed before, but not in the practical form
adopted in my Invention.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Spencer in the Great Seal Patent Office on
the 1st December 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
SPENCER, Civil Engineer, 77, Cannon Street, London, send grecting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of June, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said George Spencer, Her special licence,
that I, the said George Spencer, my executors, administrators, and
assigns, or such others as I, the said George Spencer, 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 lawfully 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
BEARING SPRINGS TO BE USED FOR RAILWAY, TRAMWAY, AND COMMON ROAD Loco-
MOTIVES, CARRIAGES, AND TRUCKS," upon the condition (amongst others) that
I, the said George Spencer, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals,

tion, and in what manner the same was to be performed, and cause
