We, EDWIN ROBERT STANDFIELD, Medical Electrician, and THOMAS DE RENZY
HARMAN, Solicitor, both of 71 Cathedral Square, Christchurch, in the Provincial
District of Canterbury, in the Colony of New Zealand, do hereby declare the nature
of our invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
We have found in practice that supports which consist of a single prop pivoted
to the frame of a bicycle are not reliable under some conditions unless the prop is
prevented from folding upon its pivot and also from side play and the present
invention accomplishes this by causing the prop, when let down into operative
position, to engage in a retaining device upon the bracket, to which it is pivoted.
It would obviously be easy to have a clip upon the prop near its middle and
rause it to engage the rim of a wheel or member of the frame of the machine but
this would be cumbersome, could not be employed upon either side with equal
facility, and would require more manipulation than our invention which has been
devised to obtain reliability, lightness, cheapness, and especially ease in operation.
In the simplest form of our invention the prop is pivoted by a ball and socket
joint to a bracket fixed to the lower member of the frame of the cycle, beneath
which the prop folds when out of use: When let down it swings upon its pivot
and can be vibrated laterally into a channel or sheath formed upon the bracket
which limits its movement to the best angle to support the machine and also
prevents side-play.
Referring to the accompanying drawings, in which similar letters are used to
indicate similar parts in all the figures:-
Fig. 1 Is a side elevation of a bicycle fitted with our invention.
Figs. 2 & 3 Are respectively front and side perspective detail views of a bracket.
Fig. A side elevation of a ball ended prop.
Fig. Is a side elevation, and
Fig. 5 A plan of a modification, and
Fig. 6A transverse sectional elevation of a serend modification.
Referring first to Figs. 1 to 3: The bracket (a) is made in two parts and
clamped to the frame (b) by screws (c).
The end of the prop () is provided with a ball (e) which is received by a
socket (f) formed in the bracket (a).
The ball is got into the socket by passing the prop into the sheath from the
inside of the bracket, the tube of the frame of the bicycle when the bracket is
clamped upon it, preventing the return of the hall,
A guide or sheath (g) projecting downwardly from the bracket (a) has an
opening (h), which permits the prop to be folded up when out of use; and two
recesses or channels (i) into one or other of which the prop takes when required to
support the machine.
In the modification shown in Figs. 4 & 5, the prop which has a bifurcated end
is hinged to a swivel piece (k) pivoted by a pin (¹), to the top of the bracket (a)
whereby it may be let down upon either side of the machine.

page_text: es in the bifurcated end of the prop, which receive the pin (7) hinging it to
the swivel piece, are made oblong so that the prop, when let down, is able to pass
over the ear (m) upon the bracket and then, when the machine is slightly inclined
a lip (n) at the junction of the bifurcation, takes into a recess (o) formed in the
lower end of the ear (m). A second car, similar to ear (m) may be employed upon
the other side of bracket (a) for use when the prop is required to operate upon
either side of the machine.
In Figure 6 The same means of swivelling the prep upon the bracket is employed,
but the prop has a projection (p) which takes into a recess formed in the bracket,
the prop being formed with an eye (r) instead of a bifurcated end, and the ear upon
the bracket being dispensed with.
We prefer the mode of carrying our invention into practice described in
reference to Figs. 1 to 3, but the details may be varied without departing from
the spirit of our invention.
Having now particularly described our invention and in what manner the same
is to be performed, we declare that what we claim is,-
1. In a bicycle support consisting of a prop pivotally connected to a bracket
clamped to the frame, means for preventing side-play of the prop and for retain-
ing it at the best angle to support the machine substantially as described and
illustrated.
2. In combination a prop pivotally connected to a bracket clamped to the frame
of a bicycle a sheath projecting from the bracket having channels, into one or
other of which the prop takes when required to support the machine substantially
as and for the purposes herein described and illustrated in Figs. 1, 2, 3, and 3^.
3. A prop having a bifurcated end in which are oblong holes receiving a pin
hinging the prop to a swivel piece pivoted upon the bracket, clamped to the frame
of a bicycle. An ear upon the bracket passing between the bifurcation and a lip
upon the prop taking into a recess in the ear substantially as and for the purposes
herein described and illustrated, in Figs. 4 & 5.
4. A prop one end having an eye in which is an oblong hole receiving a pin,
hinging the prop to a swivel piece pivoted upon the bracket clamped to the frame
of a bicycle a projection upon the prop taking into a recess in the underside of the
bracket when the prop is in supporting position substantially as and for the
purposes herein described and illustrated, in Fig. 6.
