Improvements relating to the Frames and Wheels of Rear-driving
Safety Bicycles, Applicable also to other Velocipedes.
We, GEORGE LEONARD MORRIS, WILLIAM THOMAS WILSON, and NATHANIEL HENRY
STRICKLAND, trading as G. L. Morris, Wilson & Co. of the Referee Cycle Works,
66 Turnmill Street, London, E.C., Cycle Makers, 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, reference being also had to the
accompanying two sheets of drawings wherein Figure 1 is a side elevation of our
improved frame and wheels, Figure 2 a vertical section through the centre of wheel, and
Figures 3, 4, and 5 sections of frame taken on line A B, Figure 1. Figure 6 is a vertical
sectional elevation of frame taken on line C, D, Figure 8; Figure 7 a horizontal
section taken on line E, F, Figure 1; Figure 8 being a plan of frame :-
Our invention has reference to the improved construction of the frames and wheels
of velocipedes, and consists in the employment of sheet metal of any known kind,
such for instance as sheet steel, or of any material capable of being used in sheet form
such as papier-mâche, wood, cardboard or the like, the metal or material being built
up in such a manner as to form a box-like enclosing framework and wheels of very
light construction.
"In the case of the primary application of our Invention, viz.: in the construction
of a rear driving safety bicycle, we dispense with the tubular framework, bars and
stays ordinarily employed, and, in lieu thereof, make use of a sheet or sheets a of metal
or other material. This framework of sheet metal, papier-mâche or the like is attached
by a socket or pin to the steering post from which it extends rearwards on each side
of, so as to partially enclose the rear wheel. A separate sheet or strip a Figures 6
and 7 of metal or other material is contained in the rear portion of the main frame and
is of a curvature corresponding to that of the rear wheel from which it is separated a
suitable distance apart. The edges of the sheet or sheets a when thus fitted together
may be folded over and afterwards brazed or otherwise secured; or, separate strips or
narrow sheets a Figure 5 running parallel with the edges of the sheet or sheets a
might be employed, these strips or parallel sheets a¹ overlapping the edges of the
frame a to which they are brazed or otherwise secured. The frame may
be of any
suitable shape such as a diamond frame" or the like; the bearings, chain and chain
wheel, seat pillar and other details being arranged in any convenient manner.
In the construction of wheels, we employ circular discs 6 Figures and 2 of sheet
metal or other material, such for instance as that hereinbefore specified, forming the
enclosing sides of the wheel. These circular discs or sheets bare of a slightly dished,
conical shape, being enlarged somewhat at the centre, where attached or mounted on
the axle, from which they extend so as to nearly come in contact with each other at or
about their peripheral edges where they are provided with a rim or felloe within which
the tyre is fitted in position by any suitable means. The axle or spindle passes through,
or is otherwise attached, to the centre of the circular discs composing the wheel which
thus constitutes a chamber or enclosing box like casing.
A velocipede constructed as above described with the frame and wheels composed of
sheet metal or other material made up in a box-like enclosing manner is rendered
extremely light, yet strong, whilst the frame, being rigid, maintains the bearing centres
the requisite distance apart. This construction also renders the cost much less than
is the case with velocipedes having frames composed of tubes or bars and wheels
built up with spokes and having the necessary attendant fittings.

page_text: 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 :-
1. The improvements relating to the frames and wheels of rear driving safety
bicycles, applicable also to other velocipedes substantially as herein set forth.
2. In velocipedes the employment of an enclosing box-like frame composed of sheet
steel or like metal papier-mâche, wood, cardboard, or other like material, the edges of
the frame being brazed together or secured by separate strips of metal or material
substantially as herein set forth and shown.
3. In the construction of wheels for velocipedes the use of circular discs of sheet
metal or other material such as that herein specified, the two discs being united at their
peripheral edges by a rim or felloe which contains the tyre substantially as herein set
forth and shown.
