AN IMPROVED SAFETY PERAM- BULATOR
Year: 1884

page_text: GEORGE SMITH 362 Queens Road Cheetham Manchester, Perambulator Maker,
do hereby declare the nature of my invention for AN IMPROVED SAFETY PERAM-
BULATOR to be as follows:-
At the back of an ordinary perambulator is fixed two slender springs A. B. the
other ends of which are supplied with two small wheels, C. D. projecting towards
the back of the carriage. The wheels C. D are mounted on two curved forks E. E.
so as to swival when rounding a curve,
Greater ease in guiding is insured by this arraignment, as the centre wheels F. G
can be placed nearer the centre of gravity than in ordinary carriages, thereby
enabling the attendant to raise the front wheels from the ground with a minimum
of force, as the springs A. B. yield readily for all ordinary guiding, the stops J. J.
preventing the springs from moving too far.

page_text: I, GEORGE SMITH of 362 Queens Road Cheetham Manchester, Perambulator
Manufacturer, do hereby declare the nature of my invention for AN IMPROVED
SAFETY PERAMBULATOR and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following.statement:-
To accomplish my improvements I affix, at the back end of the perambulator,
two springs, or. it may be one spring, which may be attached in any convenient
manner, but by preference to the frame carrying the main springs, or to the axle-
tree. These springs (or spring) have each, at the back end thereof, a forked frame
carrying a small wheel, mounted in such manner as to swivel when passing round
a curve. The object of mounting these trailing wheels, or wheel, upon springs, or a
spring, is to enable such a constructed perambulator to be raised in the front, for the
purpose of mounting a curb or other obstruction.
The main driving wheels are, by this means enabled to be fixed nearer the
perpendicular line passing through the centre of gravity, and thus gives improved
safety in use.
But that the improvements may be better understood, I will, by the aid of the
accompanying drawing, proceed to more fully describe means employed by me.
DESCRIPTION OF DRAWINGS.
The figure represents an outline side elevation of a perambulator constructed
according to my improvements. a, a, is the body of the vehicle, and b, b, is a main
driving wheel, upon the axle of which the perambulator is, so to speak pivoted.
c, c, is a front wheel, and d, d, a back trail wheel carried by the forked frame e, c.
This frame is attached, by pin joint, so as to be capable of a swivel motion, to the
end of the spring f, f. The top or ornament g, regulates, by coming in contact
with the main spring or fiame, the extent to which the vehicle may be turned
upon the axle b₁. The front wheel c, c, may be double or single, and the trail
wheel d, d, may be either one in the centre, or may be two separately mounted
wheels, or a double wheel mounted upon one spring, as may be preferred.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
The constructing of perambulators with an additional wheel or wheels, capable
of a swivel motion, at the rear of the vehicle, and fixed at the end of a spring or
springs, regulated by a stop, enabling the main wheels to be brought nearer the
line of gravity for the purpose and in manner substantially as shewn and described.
