Improvements in or applicable to Velocipedes.
I JOHN HENRY MUMFORD of 93 High Street, West Cowes, in the Isle of
Wight and County of Hants, Refreshment House Keeper do hereby declare the
nature of this invention to be as follows
:-
This invention relates to means or apparatus formed with or applicable to a
velocipede either a bicycle or other cycle machine adapted to control the motion of
the guiding wheel or to aid therein when required.
The improved parts consist of a strap or other connection to be applied to the
head of the machine or the stem of the guiding wheel, or wheels, support and
this strap carries two projections or arms or an equivalent part carrying runners
or anti-friction parts, which parts press against the face of a plane or approxi-
mately flat face of a tee piece, the leg of which traverses in a part cylinder or
bearing, or part cylinders or bearings suitably carried from the relatively fixed
part of the machine which forms the abutment and this tee piece is prevented
from escape and from rotation by a fin or otherwise.
Around the leg of the tee piece is formed an enlargement the shoulder of
which presses on one end of a coiled spring, or its equivalent, whilst the other
end of said spring rests upon the supporting bearing in which the leg traverses
and which forms thereby an abutment to the spring when compression takes place.
In operation as the head of the guiding wheel is turned by the rider one or
other projection or arm and runner presses down the tee piece head and com-
presses the spring so that when the power of the rider ceases to be exerted to
turn the head the spring presses out the tec piece head and that tends auto-
matically to square the arms on its surface and straighten the guiding wheel or
wheels to the same plane of motion as the other wheel, or wheels.

COMPLETE SPECIFICATION.
Improvements in or applicable to Velocipedes.
1-JOHN HENRY MUMFORD of 93 High Street, West Cowes, in the Isle of
Wight and County of Hants, Refreshment House Keeper 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 means or apparatus formed with or applicable to a
velocipede either a bicycle or other cycle machine adapted to control the motion
of the guiding wheel or to aid therein when required.
The improved parts consist of a strap or other connection to be applied to the
head of the machine or the stem of the guiding wheel, or wheels, support and
this strap carries two projections or arms or an equivalent part carrying runners
or antifriction parts, which parts press against the face of a plane or approximately
flat face of a tee piece, the leg of which in a part cylinder or bearing or part
cylinders or bearings suitably carried from the relatively fixed part of the machine
which forms the abutment and this tee piece is prevented from escape and from
rotation by a fin or otherwise.
Around the leg of the tee piece is formed an enlargement the shoulder of which

page_text: presses on one end of 'a coiled spring, or its equivalent, whilst the other end of said
spring rests upon the supporting bearing in which the leg traverses and which forms
thereby an abutment to the spring when compression takes place.
In operation as the head of the guiding wheel is turned by the rider one or other
projection or arm and runner presses down the tee piece head and compresses the
spring so that when the power of the rider ceases to be exerted to turn the head the
spring presses out the tee piece head and that tends automatically to square
the arms on its surface and straighten the guiding wheel or wheels to the same
plane of motion as the other wheel, or wheels.
Figure 1 shews by perspective view a portion of the stem g of the guiding wheel
of a velocipede and is the backbone hinged to g.
Figures 2, 3 & 4 are details.
Figure 5 shows a sectional plan taken on the line 1-1 of Figure 6.
Figure 6 is a side view of the parts shewn by Fig. 1 at an inclination.
a, a are horns or projections strapped to or fastened upon the head and these
projections carry the guide way piece a³ by its being recessed in the ends of horns a
and secured thereto.
Upon the back bone are two straps b, bor equivalent parts (see details
Figs. 3 & 4 respectively) provided with holes 63, 62 in which rides the tee piece c,
the larger and circular diameter being held in the opening 3 whilst the smaller and
squared part c¹ is held with capability of sliding to and fro, but not of turning, in
the hole b. The front edge of the tee piece c is (as will more clearly be seen by
reference to Fig. 1) recessed at e³ and is provided with antifriction rolls d, d which
press on the guide piece a³, whilst this guide piece is held within the recess c³ by
the pressure of the spring e by its abutting at one end against the shoulder c² and at
its other against the piece b'.
The parts will be modified in detail, or the arrangement of rotating and sliding
parts inverted according as the type of machine varies, or is a "socket steerer," or
a centre steerer."

In any case the constant tendency of the spring impelled tee piece is to "square"
the leading guiding wheel.
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
1. The means or apparatus for attachment to the parts of a cycle or velocipede
substantially as described for the purpose of giving a normal impelling pressure to
a part or parts on the stem of the guiding wheel to cause that wheel to preserve its
parallelism with or identity of the line of travel of the following wheel, or wheels.
2. The herein before described spring impelled tec-piece on the one part of a
velocipede coöperating with a "squaring" projection on the other portion of the
same so as to induce a constant or normal tendency for the guiding wheel to follow
a track parallel to the following wheels or in a straight line therewith.
