Improvements in the Construction of Frames for Bicycles and other
Cycle Machines.
I, JAMES LONG, of 6, Millbank Street, S.W., London, Engineer and Inventor,
do hereby declare the nature of this invention to be as follows:-
The construction of the frame is of a D form and consists of a metal tube or
bar placed horizontally and is a continuation carried forward from or near the
crank bracket of the back fork or forks curved upwards, brought round, and
carried back to or beyond the seat pillar. The front fork head is connected to the
frame by the means of an adjustable fitting to admit of the fork or forks being
adjusted to any angle. The tension of the frame is controlled by the means of an
adjustable spring support to allow the frame being altered so as to equalize the
weight of different riders. The joint or joints of the frame can be brazed or
otherwise fixed. In ladies machines a slight alteration allowing the rider to
mount from the front of the saddle is necessary this can be done by commencing
the frame at or beyond the front fork head and terminating at or beyond the
saddle or the construction can be reversed by working the frame from the saddle
to the front fork head or beyond.
The above is a spring frame.
Improvements in the Construction of Frames for Bicycles and other
Cycle Machines.
I, JAMES LONG, of 6, Millbank Street, S.W., London, Engineer and Inventor,
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 follow-
ing statement:—
**
The construction of the frame is of a D form and consists of a metal tube or
A" and is a continuation carried for-
bar placed placed perpendicular marked
ward from or near the crank bracket of the back fork or forks, curved upwards
brought round and carried back to or beyond the seat pillar socket under the
seat of the rider or otherwise. The front fork head is connected to the body of
the frame marked A" by the means of an adjustable fitting marked "C" to
admit of the fork or forks being adjusted to any angle by sliding up or down
body of frame marked "A" or by other method of adjustment.

The tension of the frame is controlled by the means of an adjustable spring

page_text: support marked "B" to allow of the frame being altered so as to equalize the
weight of different riders. The joint or joints of the frame can be brazed or
otherwise fixed.
In ladies machines a slight alteration allowing the rider to mount from the
front of the saddle is necessary this can be done by the frame being of a circular
or curved form open at the top and placed perpendicular and could pass through
the pedal wheel bracket the bracket would be fixed about the middle of the cir-
cular part of the frame at the bottom with an additional space to hold the back
fork behind the spindle of chain chank or pedal spindle.
The front fork being adjustable as in frames for gentlemens machines.
And also with a moveable forked rod with spring attachment as in gentlemens
connected and adjusting with fork of back wheel.
The above frames are spring frames the said frame or frames can be constructed
of any gauge of material solid or hollow and may be in substance of any length
breadth thickness or diameter and adequate in strength to carry several riders
at the same time on a single machine such as is termed in the cycle trade a
tandem.
The tension of the frame is controlled by the means of an adjustable spring
support attached to or near the seat pillar containing a spring of rubber, metal,
or other substance the bottom of rod forms a fork and rests on the forks or other
part of the frame containing the back wheel, and is adjustable from the pedal
wheel bracket back to the hub of the back wheel.
The front fork head being connected to the frame by the means of an adjustable
fitting allows the front fork to be placed at such an angle that the front wheel
may be extended several inches further forward thereby lowering the frame and
bring the rider nearer the ground.
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:-
--
1st. The main portion of the frame from the crank bracket to the tension red
marked "A" either as a spring or rigid construction.
2nd. I claim the tension rod with spring in the socket likewise to utelize the
said tension rod as a fork for a wheel, the part of frame marked "B."
3rd. The adjustable front fork head as connected with the frame by this or other
method of construction so that the space between the wheels may be contracted
or increased marked "C.”
4th. I claim this for any cycle frame.
