Improvements relating to Velocipedes to Facilitate Mounting and
Dismounting.
I, JAPH JOHN MASON, of 51, Victoria Street, Westminster, in the County of
London, Manager of a Company, do hereby declare the nature of this invention
to be as follows:-
"
My invention has for its object to provide in velocipedes which have what is
now known as free-wheel" arrangements means for enabling the rider to mount
and dismount from the pedal without the necessity of waiting until such pedal
is at its lowermost position.
According to my invention I suitably attach, either to the back stay or some
other part of the machine or to the pedal crank, a trip or pawl and on to the part
to which the said trip is not attached I may fix a suitable stop, or alternately the
said trip may engage directly with the back stay or other part of the machine.
When the crank axle is rotated in a forward direction in the usual way the
trip merely touches the said stop or part of the frame but upon the rider back-
pedalling to a predetermined point, the trip will become engaged and thereby
enable the rider to put his weight upon the pedal and dismount.
The trip, or the part of the machine which it wipes, may be faced with leather,
rubber or similar material to avoid contact between the two metal surfaces.

Improvements relating to Velocipedes to Facilitate Mounting and
Dismounting.
I, JAPH JOHN MASON, of 51, Victoria Street, Westminster, in the County of
London, Manager of a Company, 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:
1
My invention has for its object to provide in velocipedes and more especially
those which have what is now known as a "free-wheel," means for enabling the

page_text: rider to mount and dismount from the pedal without the necessity of waiting
until such pedal is at its lowermost position.
In the accompanying sheet of drawings I have illustrated three alternative
ways of carrying out my invention.
Figure 1 shows in side elevation the bottom bracket and adjacent members of
a rear-driven bicycle; the chain, sprocket wheel and other far details being
omitted for the sake of clearness.
Figure 2 is a transverse section on the line A-B Figure 1.
Figure 3 is a part view similar to Figure 1, and
Figure 4 is a transverse section on the line C-D) Figure 3 of a modification, and
Figure 5 is a transverse section of a further modification.
Similar letters refer to similar parts throughout the several views.
a represents the bottom bracket, the crank, and c its axle. d, d are the
tubular frame members and e, e are the back stays.
According to my invention I attach either to one of the back stays e or to one
of the cranks or to some other convenient part of the machine a trip or pawl f
fulcrumed at the point g. The trip may be attached to the machine or member
by such means as the band clamp à held in position by a bolt i and which band
clamp might be adjustable. In the arrangements illustrated in Figures 1, 2 and 5
the trip is carried by the bolt i, and in that shown in Figures 3 and 4 it is
mounted upon a second bolt or spindle carried in a lug g of the band clamp h.
In Figures 1 and 2 the back stays e are shown as being circular in transverse
section and Figures 3 and 4 show them as being of D-section In the latter case
the bolt screws into ears of the band clamp and it may be retained in position
if necessary by a lock nut k.
A spring serves to return the trip or pawl f to
its normal position.
When the crank is rotated in a forward direction, as indicated by the arrows,
the trip is merely actuated against the resistance of the spring but upon the
rider back-pedalling to a predetermined point the crank will become engaged
by the trip and further backward movement prevented, thereby enabling the
rider to put his weight upon the pedal and dismount.
In the arrangement illustrated by Figure 4 the trip f has a tail m which when
the trip becomes effective butts upon the distant back stay e or equivalent part of
the machine and thereby increases the rigidity of the arrangement.
The trip, or the part of the machine which it wipes, may be faced with leather,
rubber, or other suitable material as indicated at n to avoid contact between two
metal surfaces.
When the arrangement described with reference to Figure 5 is employed I
may attach to the back e or other stationary member a band-clamp ó having
a projection that serves as an abutment for the trip f.
The cranks may be of any suitable transverse section; Figures 1, 2, 3 and 4
show them angular and Figure 5 circular.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is-
1. An attachment to a velocipede to facilitate mounting and dismounting
comprising a trip, so mounted upon some convenient part of the machine, or upon
the crank, that upon the rider back-pedalling to a predetermined point the crank
is prevented from further backward movement substantially as set forth.
2. In an attachment to a velocipede to facilitate mounting and dismounting
a trip so arranged that a tail thereof, when the trip is in action, butts against the
back stay or equivalent part of the machine substantially as set forth.
3. The combination, with a trip to facilitate mounting and dismounting a
velocipede, of a facing of leather or equivalent material to avoid contact between
two metal surfaces substantially as set forth.
4. An attachment to a velocipede to facilitate mounting and dismounting com-

page_text: prising a trip and an abutment, the one on a movable and the other on a stationary
member substantially as set forth.
5. The attachment to velocipedes to facilitate mounting and dismounting sub-
stantially as described and illustrated in the accompanying drawings.
