PROVISIONAL SPECIFICATION.
Improved Bicycle Support.
ROBERT CAMPBELL MANN of Ditchingham in the County of Norfolk, Malster, do
hereby declare the nature of this invention to be as follows:-
This improvement consists of an arm or raking shore hinged in a way hereinafter
described, to the frame of the bicycle preferably at a point near the offside bearing of
the back wheel and furnished with means by which it is securely clipped to the frame
of the machine preferably to the offside backstay when out of use.
The hinge end of the raking shore is furnished with an eye which fits over the end
of a pin or bolt upon which are also the two half clips of a clamp to embrace the
backstay. The eye is formed of spring steel or other suitable material, and has a
saw cut in a plane at right angles to the axis of the pin or bolt on which it fits.
Hence when the nut on the end of the pin or bolt is screwed up to fix the clamp
on the frame of the bicycle, the saw cut permits the eye to be slightly compressed
and causes the eye of the arm to fit somewhat stiffly between the collar of the pin
and the offside clip of the clamp.
The clamp is fitted upon the back stay in such a position that the bolt or pin on
which the eye of the raking shore fits, has its axis in a plane inclined to the vertical
centre line of the machine, and also in a plane at an obtuse angle with a plane
in which the vertical centres lines of the machine forward of the centre line of the
back wheel all lie, so that when the raking shore is turned down to support the
machine, its end describes an arc in a forward as well as in an outward direction.
The machine when slightly inclined to the offside is supported by the raking shore,
because the points of contact with the ground, of the front wheel, back wheel and
raking shore, are at the three angles of a triangle, within which a vertical line from
the centre of gravity of the machine then falls.
Upon the same backstay is another clip, which carries a projection or groove with
which a sliding catch carried by the raking shore, engages to keep the raking shore
firmly against the backstay, when not in use.

Improved Bicycle Support.
ROBERT CAMPBELL MANN of Ditchingham in the County of Norfolk, Maltster
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 improvement consists of an arm or raking shore hinged in a way hereinafter
described to the frame of the bicycle preferably at a point near the offside bearing
of the back-wheel and furnished with means by which it is securely clipped to
the frame of the machine preferably to the offside back-stay when out of use.
The hinge end of the raking-shore is furnished with an eye which fits over
the end of a pin or holt upon which are also the two half cips of a clamp to
embrace the back-stay. The eye is formed of spring steel or other suitable

page_text: material, and has a saw-cut in a plane at right angles to the axis of the pin or
bolt on which it fits. Hence when the nut on the end of the pin or bolt is
screwed up to fix the clamp on the frame of the bicycle, the saw-cut permits the
eye to be slightly compressed, and causes the eye of the arm to fit somewhat
stiffly between the collar of the pin, and the offside clip of the clamp.
The clamp is fitted upon the back-stay in such a position that the bolt or pin on
which the eye of the raking-shore fits, has its axis inclined so that when the
raking-shore is turned down to support the machine, its end describes an arc in a
forward, as well as in an outward direction.
The machine when slightly inclined to the offside is supported by the raking-shore,
because the points of contact with the ground of the front-wheel, back-wheel, and
raking-shore, are at the three angles of a triangle, within which a vertical line from
the centre of gravity of the machine then falls.
Upon the same back-stay is another clip which carries a projection or groove with
which a sliding catch carried by the raking-shore engages to keep the raking-shore
firmly against the backstay when not in use.
DESCRIPTION OF DRAWING.
Fig. 1 is a diagramatic side view of a bicycle, and Fig. 2 a diagramatic end view
from the rear, showing the raking shore "A" down in a position to support the
bicycle, it is hinged at "D" in such way as to describe the forward and sideward
curve a " when put down or up. The sliding catch "B" engages with the
clip "C" when the shore "A" is turned up against the backstay, as indicated by
the dotted lines.
"
Fig. 3 is a plan of the raking-shore "A" to a larger scale than Figs. 1 and 2, and
Fig. 4. is a side view of sanie, showing the hinge or joint "D," the clamp "E" for
fixing to the backstay, and the sliding catch "B."
Figs. 5 and 6. are front and side views respectively of the clip "C," with the
projection "F" with which sliding catch "B," engages to keep the shore "A"
secured to the backstay.
Figs. 7 and 8 are front and side views respectively of a modified form of
clamp "E," with joint pin "D" to attach shore "A," and clamp bolt "G" to secure
the clamp to the backstay.
Fig. 9 shows the stamping of which clamp "E" is formed.
Fig. 10 shows the stamping bent to suit a backstay of "D" section.
Fig. 11 shows the clamp "E" fixed to the backstay by the bolt "G," while the
shore "A" is shown turned down on the pin "D" to its position when supporting
the machine.
Figs. 12, 13 and 14 are respectively side view, front view, and plan of a modified
form of clip "CC" and sliding catch "B" to secure shore "A" against the
backstay when turned up against same, out of use. The part of the clip is bent
round the back-stay, and is kept in place by bending the edges of "C" over the
edges of "C" flanged as shown. The groove "f1" receives the sliding catch "B"
and compresses it upon "A"; "B" being formed of a material sufficiently springy
to permit of this.
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
A raking shore hinged and secured to the frame of a bicycle substantially as and
for the purpose described.
