I, GEORGE SPENCER, of 77 Cannon Street in the City of London, Engineer, do
hereby declare the nature of this invention to be as follows:-
My improvements in india rubber springs for use in locomotive engines, carriages,
and trucks for railways, tramways, and for other purposes, consist in various new
combinations of parts as follows:-

Improvements in India-rubber Springs for Use in Locomotive
Engines, Carriages, and Trucks for Railways and Tramways, and
for other Purposes.
I, 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:-
My improvements in india-rubber springs for use in locomotive engines, carriages,
and trucks for railways, tramways, and for other purposes (for example, as station
buffers), consist in various new combinations of parts as follow:-
Referring to the sheet of drawings filed with my provisional specification,
Fig. 1 shows a section of a spring comprising a cylinder of india-rubber A with a
perforated plate B moulded in; a cup dividing plate C and a cup end plate D.
Fig. 1 shows the perforated plate B.
Fig. 2 shows a section of a spring comprising india-rubber cylinders A, A',
provided with projections, a plate B with perforations into which the said projections
fit, a cup dividing plate C, and a cup end plate D.
Fig. 2 shows the perforated plate B.
Fig. 3 shows a section of a spring comprising a cup end plate D, a cup dividing
plate C, an india-rubber cylinder A, an outer plate B, and a nozzle ring plate b, both
moulded separately into the cylinder A thereby preserving the continuity of the india-
rubber entirely through the circular space G between B and b.
Fig. 3 shows the outer plate B and nozzle ring plate b showing the circular
space G.
Fig. 4 shows a section of a spring comprising india-rubber cylinder A, perforated
plate B, and cup dividing and cup end plates C and D. Perforations like those in
the perforated plate B are formed also in the cup dividing and cup end plates Cand D
in order to keep the india-rubber cylinder A in position.
Fig. 4 shows the perforated plate B.
Fig. 5 shows a section of a spring comprising india-rubber cylinder A, cup dividing
plate C, cup end plate D, and nozzle b. The nozzle only is moulded into the
cylinder A.
Fig. 5 shows the nozzle b.
Fig. 6 shows a section of a spring comprising india-rubber cylinder A, outer
plate B, cup dividing plate C, and cup end plate D. Only the outer plate B is
moulded into the india-rubber cylinder A.
Fig. 6 shows the outer plate B.
Fig. 7 shows a section of a spring comprising india-rubber cylinder A, outer
plate B, cup dividing plate (, cup end plate D, and nozzle ring plates b, b¹. The
outer plate B and the nozzle ring plates b, b', are moulded separately into the india-
rubber cylinder A.

page_text: Fig. 7 shows the outer plate B and one of the nozzle ring plates b.
Fig. 8 shows a section of a spring comprising india-rubber cylinder A, outer ring
plate B, cup dividing plate C, and cup end plate D. The outer ring plate B is either
moulded or forced into a groove of the cylinder A.
Fig. 8ª shows the outer ring plate B.
In all cases E is the buffer draw or guide rod, and the ring plate B should not be
of less diameter than the cup dividing and cup end plates C and D.
Nozzles b of any suitable form can be used; they may be of any of the forms
shown in the specifications of former Patents granted to me respectively No. 758
dated 24 February 1877 and No. 3410 dated 10 July 1883. Either of the springs
as shown in the drawing may be made with the india-rubber portion A conical, if
preferred. In any case the cup dividing and cup end plates may be made in any of
the forms shown in the drawing.
Having now particularly described and ascertained the nature of the said invention,
and in what manner it is to be performed, 1 declare that what I claim is :-
Springs comprising metal plates and india-rubber constructed, combined, and
arranged as hereinabove described with reference to and shown respectively in
Figs. 1 and 1ª ; in Figs. 2 and 2ª ; in Figs. 3 and 3"; in Figs. 4 and 4ª; in Figs. 5
and 5ª ; in Figs. and 6; in Figs. 7 and 7"; and in Figs. 8 and 8ª of the drawings
annexed, or modified as above set forth.
