IMPROVEMENTS IN BEARING SPRINGS FOR CARRIAGES, TRUCKS, AND LOCOMOTIVE ENGINES FOR RAILWAY, TRAMWAY, AND COMMON ROADS."
Year: 1876

page_text: LETTERS PATENT to George Spencer, Civil Engineer, of 77, Cannon Street,
London, in the County of Middlesex, and Edward Spencer Stidolph, Civil
Engineer, of Langdale House, Greenwich, in the County of Kent, for the
Invention of "IMPROVEMENTS IN BEARING SPRINGS FOR CARRIAGES, TRUCKS,
AND LOCOMOTIVE ENGINES FOR RAILWAY, TRAMWAY, AND COMMON ROADS."
PROVISIONAL SPECIFICATION left by the said George Spencer and Edward
Spencer Stidolph at the Office of the Commissioners of Patents on the
27th May 1876.
GEORGE SPENCER, Civil Engineer, of 77, Cannon Street, London, in the County
of Middlesex, and EDWARD SPENCER STIDOLPH, Civil Engineer, of Langdale House,
Greenwich, in the County of Kent. "IMPROVEMENTS IN BEARING SPRINGS FOR
CARRIAGES, TRUCKS, AND LOCOMOTIVE ENGINES FOR RAILWAY, TRAMWAY, AND
COMMON ROADS."
Our improvements in bearing springs for carriages, trucks, and locomotive
engines for railway, tramway, and common roads consist in applying a pad or pads
of india-rubber or other suitable elastic material at the two ends of the laminated
steel bearing springs of carriages, trucks, or locomotive engines used on railways,
tramways, or common roads to absorb the shocks which the bearing springs sustain
from the road or wheels not being true in line or form.
In the Drawing annexed our improvements are shown. In Figs. 1 and 2 the
scroll iron A is formed so that both a bearing and rebound action is given by the
pads of elastic material. B is a ring of india-rubber or other clastic material which
acts as an assistant bearing spring. C is a ring of india-rubber or other elastic
material which acts as a rebound ring.
Fig. 3 shows a modification of assistant bearing springs in which no rebound
spring is used. These are shown hung in a vertical position, but they may be hung
at an angle to the perpendicular if desired.
By our improved form the carriage or other vehicles may be raised by means of
the screw at the bottom when required.
One object of these improvements is to give a better lateral action to the carriage
body. To effect this the spring pin may be left somewhat free in its hole D; the
hole E in the supporting bracket may be made conical, or spherical surfaces may be
used to effect the same object.

said George Spencer and Edward Spencer Stidolph in the Great Seal Patent
Office on the 20th November 1876.
GEORGE SPENCER, Civil Engineer, of 77, Cannon Street, London, in the County
of Middlesex, and EDWARD SPENCER STIDOLPHI, Civil Engineer, of Langdale House,
"IMPROVEMENTS IN BEARING SPRINGS FOR

COMMON ROADS."
Our improvement in bearing springs for carriages, trucks, and locomotive engines
for railways, tramways, and common roads consists in applying a pad or pads of
india-rubber or other suitable elastic material at the two ends of the laminated steel
bearing springs of carriages, trucks, or locomotive engines used on railways, tram-
ways, and common roads to absorb the shocks which the bearing springs sustain
from the road or wheels not being true in line or form.
In the Drawing annexed our improvement is shown. In Figures 1 and 2 the
scroll iron A is formed so that both a bearing and rebound action is given by the
pads of elastic material. B is a ring of india-rubber or other elastic material which
acts as an assistant bearing spring. C is a ring of india-rubber or other elastic
material which acts as a rebound ring.
Fig. 3 shows a modification of assistant bearing spring in which no rebound
spring is used. These are shown hung in a vertical position, but they may be
hung at an angle to the perpendicular if desired.
By our improved form the carriages or other vehicles may be raised by means of
the screw at the bottom when required.
One object of these improvements is to give a better lateral action to the carriage
body. To effect this the spring pin may be left somewhat free in its hole D; the
hole E in the supporting bracket may be made conical, or spherical surfaces may
be used to effect the saine object.
What we claim as new in our Invention is-
1st. The use of the combined bearing and rebound springs.
2nd. The use of the combined bearing without the rebound spring.
3rd. The modes of leaving the carriage body to swing laterally, as shown.
In witness whereof, we, the said George Spencer and Edward Spencer Stidolph,
have hereunto set our hand and seal, this Twentieth day of November,
in the year of our Lord One thousand eight hundred and seventy-six.
