PROVISIONAL SPECIFICATION.
An Improved Spring for Perambulators, Carriages, and the like,
Applicable also to other Purposes.
1. HENRY WILLIAM TWIGGS Perambulator Manufacturer of Victoria Street in the
City and County of Bristol do hereby declare the nature of this invention to be as
follows:-
My invention consists of an india rubber spring containing one or more coils of
steel, or other suitable spring material, solidly embedded therein. The ends of the
rubber spring are provided with ears having a central perforation. The steel coils
have looped terminations which extend into and fit within the ears of the india rubber
spring. A metal eye is passed through the central perforation of the ears and is
burred, or otherwise fastened at its opposite end which thus locks the extremeties of
the spring together and ensures their simultaneous and equal tension in operation.
The body of the perambulator or carriage is suspended from the framework by
means of a required number of springs, the eyes of which are connected respectively,
one with the framework and one with the body, by suitably formed connections
thereon.
Springs manufactured according to my invention have the advantages of very
considerable additional elasticity together with the united strength of the combined
springs and they are not only applicable to the uses mentioned herein, but are
also adapted to the general purposes for which springs of this nature are usually
employed.

An Improved Spring for Perambulators, Carriages, and the like,
Applicable also to other Purposes.
I, HENRY WILLIAM TWIGGS 5 Bond Court, Walbrook London E.C. Perambulator
Manufacturer 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:-
And in order that it may be more fully understood I accompany the same with
drawings in which similar letters of reference denote corresponding parts in my
invention. My invention consists of india-rubber containing one or more coils of
steel or other suitable spring material solidly embedded therein. The ends of the
india rubber are provided with ears having a central perforation. The steel or other
metal coils have looped terminations which extend into and fit within the ears of the
india rubber. A metal eye is passed through the central perforation of the ears
and is burred or otherwise fastened at its ends, and the extremeties of the india rubber
and the metal coil are thus locked together ensuring simultaneous and equal tension
in the operation of the spring.
Figure 1 in the drawings represents my invention as a whole A, A being the
central perforations in the ears. B B, and a, a the secured outer ends of the metal
eyes passing through the central perforations A A as described.
Figure 2 is a longitudinal section of the india rubber showing a metal spring
coil embedded therein and secured at the ends cc by the metal eyes a a passing
through the central perforations A A.

page_text: Figure 3 represents my invention with more than one metal spring coil C. C. C.
embedded and secured therein at their ends as described.
The object to be suspended, or operated by means of these springs has suitable
hooks or other means for connection with them which pass through the metal eyes C,
similar connections being provided upon the framework from which the object is
suspended or operated and which are secured in like manner to the other end of the
springs. Springs manufactured according to my invention have the advantages of
great elasticity together with the united strength of the combined springs and they
are not only applicable to the uses specified herein but are also adapted to the
general purposes for which springs of this nature are usually employed.
my
said
Having now particularly described and ascertained the nature of
invention and in what manner the same is to be performed, I declare that what
I claim is.
1st. One or more metal spring coils solidly embedded in india rubber substan-
tially as and for the purposes herein described and as shown on the drawings.
2nd. The method of and the means by which, the ends of the metal spring
coils are secured within the india rubber ensuring their equal and simultaneous
tension with the elasticity of the india rubber, substantially as, and for the purposes,
herein described and shown in the drawings.
3rd. The general construction and arrangement of parts constituting an improved
spring composed of one or more metal spring coils and india rubber united together
substantially as, and for the purposes herein described and as shown by the
drawings.
