I, ALFRED GEORGE SPENCER, of 77 Cannon Street in the City of London,
Engineer, do hereby declare the nature of this invention to be as follows:-
According to this invention the auxiliary spring, which may be of the kind
known as Spencer's india rubber cylinder spring, or of any other suitable kind, is
interposed between two cups or boxes one of which covers the other after the
manner of a box lid. The upper cup or box is able to slide between suitable guides
attached to the framing of the vehicle. The lower cup or box is connected to the
main bearing spring. Two sets of cups with interposed auxiliary spring are
used to each main spring. Two arrangements are shewn in the accompanying
drawings by way of illustration.
Fig. 1 is a side elevation, half in section. Fig. 2 is a cross section; Fig. 3 is a
plan, partly in section; Fig. 4 is an end view of one arrangement. Figs. 5. and 6
are views corresponding to Figs. 1 and 2, of a modification in which the upper cup
or box enters the lower one and the latter is provided with projections that enter
grooves or recesses in the cheeks or guides of the shoe attached to the sole of the
under frame of the vehicle to limit the relative movement of the two cups in a
vertical sense.
a is a shoe made to clip the side sole of the under frame of the vehicle; it may
be either bolted to the sole through the sides or from underneath. b is a cup made
to take a Spencer india rubber cylinder c or other suitable spring and able to
slide along the bottom of the shoe according to the expansion or contraction of the
main bearing spring d. e is a second cup, extended with two lugs at the bottom
to receive the tension bar of the bearing spring. In Figs. 5 and 6, ƒ ƒ are
projections of the lower cup, entering grooves g in the cheeks of the shoe a.

page_text: I, ALFRED GEORGE SPENCER, of 77 Cannon Street in the City of London,
Engineer, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by
the following statement:—
According to this invention auxiliary springs are applied to the main bearing
springs of railway carriages, wagons or other vehicles, in such a manner as to be
capable of a sliding movement admitting of changes of longitudinal position to
suit variations in the camber of the main spring due to changes in the load or
other cause. The auxiliary spring which may be of the kind known as Spencer's
india-rubber cylinder spring or of any other suitable kind, is interposed between
two cups or boxes one of which covers the other after the manner of a box lid.
The upper cup or box is able to slide between suitable guides attached to the
framing of the vehicle. The lower cup or box is connected to the main bearing
spring. Two sets of oups with interposed auxiliary spring are used to each main
spring.
Two arrangements are shewn in the accompanying drawings by way of illus-
tration. Fig. 1 is a side elevation, half in section. Fig. 2 is a cross section.
Fig. 3 is a plan partly in section. Fig. 4 is an end view of one arrangement.
Figs. 5 and 6 are views corresponding to Figs. 1 and 2, of a modification in which
the upper cup or box enters the lower one and the latter is provided with
projections that enter grooves or recesses in the cheeks or guides of the shoe
attached to the sole of the under frame of the vehicle to limit the relative movement
of the two cups in a vertical sense.
a is a shoe made to clip the side sole of the under frame of the vehicle; it may
be either bolted to the sole through the sides or from underneath. b is a cup made
to take a Spencer india rubber cylinder c or other suitable spring and able to slide
along the bottom of the shoe according to the expansion or contraction of the main
bearing spring d. e is a second cup, extended with two lugs at the bottom to
receive the tension bar of the bearing spring. In the arrangement Figs. 5 and 6
ff (Fig. 6) are projections of the lower cup entering grooves g in the cheeks of
the shoe a.

page_text: Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is:
1. The application of auxiliary springs to the main bearing springs of railway
carriages wagons or other vehicles in such a manner as to admit of a sliding
movement to accomodate variations in the camber of the main bearing spring
substantially as described:
2. Providing main bearing springs with auxiliary springs placed in cups
the arrangement being substantially such as described above and represented
respectively in Figa 1 to 4 and in Figs. 5 and 6 of the drawings.
