We, RICHARD HOYLE, of 4, St. Ann's Square, Valuer, and FRANK HOLLAND, of
178, Ashton New Road, Engineer, both in Manchester, in the County of Lan-
caster, do hereby declare the nature of this invention to be as follows:
This invention relates to improvements more particularly in and connected
with ladies' chain gear bicycles having what are termed dropped frames and
consists in the improved construction of the frame with the object of obtaining
greater lateral rigidity with increased clearance for the feet and dress of the rider
and in the construction and arrangement of a support for enabling the machine
to stand when the rider is dismounted.
In carrying out our invention our first improvement consists in forming the
main part of the frame, which connects and to which are secured the steering
socket, crank shaft bearing and saddle pin support, and which is usually formed
of two tubes connected together by the crank shaft bearing, by a continuous tube
which is secured to the steering socket at the front end, is carried downwards
and curved between the wheels to a few inches below the position of the crank
shaft, and then carried upwards to the saddle pin socket. Across the bend is
fixed a bridge which forms part of the crank shaft bearing. The lower back
stays from the driving wheel axle are fixed to the main tube behind the crank
shaft bearing and the upper stays to the saddle pin socket in the usual way. The
bridge aforesaid may be made in one casting or stamping with the crank shaft
bearing and formed to clip the main tube in two parts above the bend or curve,
or it may be built of castings or stampings and tubing. We prefer to use oval
tubing with the long axis in the plane of the wheels for the main tube.
Our second improvement consists in forming and attaching a hinged leg or
support to the seat post which when not required for use lies behind the seat post
and when it is required to support the machine upright upon the rider dismount-
ing, is turned downwards until its foot rests upon the ground, the machine being
slightly canted over sideways for this purpose. The support consists of a rod
fixed in a socket, which is hinged upon a stud carried by the seat post. In order
to enable the support to lie upright behind the seat post when not in use and to
remain in position when lowered, the rod is made to slide in the socket, and its
inner end to press upon the stud by means of a spring enclosed in the socket.
Preferably this inner end of the rod is pointed, and there are two or three indenta-
tions in the stud into which the pointed and of the rod enters when in the
different positions required. The stud is fixed to the back of the seat post a short
distance above the bottom back stays and may be permanently fixed, or detach-
ably by means of a clip. When not in use the foot of the support lies upward.

We, RICHARD HOYLE, of 4, St. Ann's Square, Valuer, and FRANK HOLLAND, of
178, Ashton New Road, Engineer, both in Manchester, in the County of Lan-
caster, 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 more particularly in and connected
with ladies' chain gear bicycles having what are termed dropped frames and
consists in the improved construction of the frame with the object of obtaining
greater lateral rigidity with increased clearance for the feet and dress of the rider
and in the construction and arrangement of a support for enabling the machine
to stand when the rider is dismounted.
In order that our invention may be more readily understood we will refer to the
drawings hereunto attached. In the said drawings Figure 1 represents an eleva-
tion and Figure 2 a plan of our improved bicycle frame having our improved sup-
port attached thereto. Figures 3 and 4 represent two views of our improved
support for attachment to the seat post, and Figures 5 and 6 similar views of
the same for attachment to one of the legs of the lower fork or one of the lower
stays.

In carrying out our invention our first improvement consists in forming the
main part of the frame, which connects and to which are secured the steering
socket a, crank shaft bearing and saddle pin support c, and which is usually
formed of two tubes connected together by the crank shaft hearing, by a con-
tinuous tube e which is secured to the steering socket a at the front end, is carried
downwards and curved between the wheels to a few inches below the position of
the crank shaft and then carried upwards to the saddle pin socket e¹.
the bend is fixed a bridge which forms part of the crank shaft bearing b. The
lower back stays forming the fork from the driving wheel axle to the
crank shaft bearing bare fixed to the main tube behind the said crank shaft and
the upper stays h are fixed to the saddle pin socket in the usual way. The bridge f
aforesaid is preferably made in one casting or stamping with the crank shaft
bearing and formed to clip the main tube in two parts above the bend or curve
at el but it may be built up of castings or stampings and tubing, by brazing in
the ordinary way. We prefer to use oval tubing with the long axis in the plane
of the wheels for the main tube e.
The
Our second improvement illustrated in the several views consists in forming
and attaching a hinged leg or support to the seat post or tube or other suit-
able part such as the stay g' g which when not required for use lies behind the
seat post or other part and when it is required to support the machine upright
upon the rider dismounting is turned downwards until its foot rests upon the
ground, the machine being slightly canted over sideways for this purpose.
support consists of a rod j fixed in a socket which is hinged upon a stud /
carried by the seat post or other part. In order to enable the support to lie upright
behind the seat post when not in use and to remain in position when lowered, the
rod is made to slide in the socket, and its inner end is formed with a head
which is pressed upon the stud by means of a spring m enclosed in the socket,
the stud having flats formed upon it. This inner end of the rod may be
pointed, and two or three indentations made in the stud into which the pointed
end of the rod enters when in the different positions required. Preferably how-
ever the rod end and stud are formed as previously described. The stud 7 is some-

page_text: times fixed to the back of the seat post e a short distance above the bottom back
stays and may be permanently fixed or detachably by means of a clip. Prefer-
ably however the stud forms part of a clip n. Figures 3 and 4 by which the sup-
port can be readily attached to and removed from a bicycle. Sometimes it is pre-
ferable to fix the support to one of the lower back stays gl and in the position
illustrated in Figure 1. In this case, a suitable clip is formed according to the
sectional form of the said stays. In Figures 5 and 6 a clip suitable for what are
known as D section stays is illustrated. The dotted lines in Figure 3 indicates
the relative position of the sockets and support when the latter is in a position for
supporting the bicycle. In Figure 5 the dotted lines indicate the position of the
support when not in actual use.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
First The improved construction of bicycle frame which consists in forming
the main limb or backbone of a single length of tubing terminating at one end
with the steering socket, at the other end with the saddle pin socket and forming
a return bend intermediate between the wheels, across which bend is fixed a
bridge carrying the crank axle bearing substantially as herein before described
and illustrated with reference to Figures 1 and 2 of the drawings.
Second: The improved construction and arrangement of a support for bicycles
in which a leg is pivoted in a bearing fixed to a suitable part of the framework
so as to lie close to the same when not in use, and be capable of lateral movement
to bring its end in contact with the ground when required substantially as and
for the purpose herein before described and illustrated with reference to the several
figures of the drawings.
