Improvements in Steering Gear for Road Carriages Driven by
Mechanical or Animal Power.
1, FREDERICK RICHARD SIMMS, of 49, Leadenhall Street, in the City of
London, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in steering gear for road carriages driven
by mechanical or animal power.
In carrying out my invention I arrange either the two fore wheels or the two
hind wheels on independent axles pivoted vertically to the framing of the carriage
so that the wheels can be turned, and in order that they can be turned simultaneously
I provide each axle with a toothed sector with both of which engages a toothed
wheel which when rotated by a steering handle turns both wheels in the same
direction.
In some cases I operate both the fore and hind wheels in which case I may
arrange them as above described or mount each pair on one axle in the ordinary
way the said axles being each arranged to turn on a central vertical pivot. In
order that when one axle is turned about its pivot the other shall correspondingly
turn but in the opposite direction I provide each axle with a tooth sector both of
which gear together.

Improvements in Steering Gear for Road Carriages Driven by
Mechanical or Animal Power.
I, FREDERICK RICHARD SIMMS, late of 49, Leadenhall Street, now of
Amberley House, 12 Norfolk Street, Strand, 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:-
This invention relates to improvements in steering gear for road carriages driven
by mechanical or animal power.
In carrying out my invention I arrange either the two fore wheels or the two
hind wheels or both fore and hind wheels on independent axles pivoted vertically
to the framing of the carriage so that the wheels can be turned, and in order that
they can be turned simultaneously I provide each axle with a toothed sector with
both of which a toothed wheel engages so that when the said toothed wheel is
rotated by a steering handle it turns both wheels in the same direction.
I sometimes operate both the fore and hind wheels, in which case I may arrange
them as above described or mount each pair on one axle in the ordinary way the
said axles being each arranged to turn on a central vertical pivot. In order that
when one axle is turned about its pivot the other shall correspondingly turn, but
Drive Bd.1

page_text: in the opposite direction, provide each axle with a toothed sector noth of whien
gear together.
To euable my invention to be fully understood I will describe it by reference to
the accompanying drawings, in which :-
Figure 1 is a plan of two of the wheels of a road carriage provided with steering
gear according to my invention :
Figure 2 is a front elevation of part of the same :
Figure 3 is a view similar to Figure 1 but shewing the wheels turned on their
pivots:
Figures 4, 5 and 6 are views similar to Figures 1, 2 and 3 of a slightly modified
form of steering gear:
Figure 7 is a plan of the wheels of a road carriage the axles of which wheels
are connected together by toothed sectors:
Figure 8 is a similar view but shewing the wheels turned on their pivots.
Similar letters of reference indicate the same or corresponding parts in all the
figures.
The
a, a are the carriage wheels and b, b the independent axles of the same.
.axles b, b are connected to vertical spindles c, c connected to the frame of
the carriage (not shewn in the drawings).
d, d Figures 1 to 8 are the toothed sectors connected to the axles b, b. In
Figures 1 to 6 the toothed sectors d, d gear with an intermediate toothed wheel e
mounted on a vertical spindle el connected to the framing of the carriage so that
both wheels a, a can be turned, at the same time, by this spindle e which is
operated by a suitable hand wheel or the like. In Figures 1, 2 and 3 the sectors
are similar and the wheel e is mounted centrally so that both wheels are rotated
through the same angle. A second intermediate toothed wheel adapted to
engage with toothed sectors on the other pair of wheels of the carriage, is in
connection with the wheel e by a chain or the like so that they turn together..
In Figures 4, 5 and 6, the toothed sectors d, d and the intermediate wheel e are
shewn eccentric so that the two wheels are turned through different angles as shewn
clearly in Figure 6.
In the arrangement shewn in Figures 7 and 8 only two axles are employed, that
is to say, the two front wheels are mounted on one axle and the two hind wheels
on the other axle. In this case also the sectors d, d engage with one another so that
the front and hind wheels turn simultaneously.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In road carriages, mounting the wheels on axles pivoted vertically and
providing means for turning the wheels on their pivots, substantially as, and for the
purpose, hereinbefore described.
2. In road carriages, mounting each wheel on an independent axle pivoted
vertically and providing each axle with a toothed sector each pair of sectors being
adapted to engage with a toothed wheel, substantially as, and for the purpose,
hereinbefore described.
3. In road carriages, mounting the two axles on vertical pivots and providing the
said axles with toothed sectors adapted to engage with one another, substantially
as, and for the purpose, hereinbefore described.
4. The manufacture and use of the improved steering gear hereinbefore described
and illustrated in Figures 1, 2 and 3; 4, 5 and 6; and 7 and 8 respectively of the
accompanying drawings.
