PROVISIONAL SPECIFICATION.
Improvements in and relating to the Construction of Frames for
Velocipedes.
We CHARLES MONTAGUE LINLEY, of 16 Carmalt Gardens, Putney, in the
County of Surrey, and JOHN BIGGS of 57 Lynette Avenue, Clapham Common,
Clapham, in the County of Surrey, both Engineers, do hereby declare the nature
of this invention to be as follows:-
Our invention relates to an improvement in the construction of the junction and
other pieces in the frames of velocipedes which cannot be made out of the tube of
which the members of the frame are constructed, and which at the present time are
either drop stampings or malleable castings, and it has for its object, increased
strength, dispensing with the machining of the parts, and therefor a saving in
-first cost.
We attain this end by constructing these junction and other pieces of sheet steel
stampings-each piece being formed of two stampings which when rivetted and
brazed together form the desired part or piece.
The size and shape of the pieces will obviously vary according to the frame for
which they are intended, but it will be seen that by constructing these parts or
pieces in the manner hereinbefore described they can be made as light. as possible,
being mere shells in many cases, and of the exact shape required, thus obviating
the necessity of any machining.
In order that our invention may be fully understood, we will by way of
illustration describe the construction of one part or piece according to our inven-
tion. We will take the slotted end of a main frame adapted to receive the axle of
the driving wheel as an example. This consists of a flat slotted plate, having one
or two circular projections, adapted to receive the tubular members of the frame.
We stamp out of a piece of sheet steel two blanks of the desired shape, and either
at the same operation, or subsequently, block or raise up those parts intended to
form the circular projections into semi-circular form. These two pieces are then
fixed together by transverse rivets, the brazing being effected when the said part
is brazed on to the member or members of the frame adapted to carry it.

COMPLETE SPECIFICATION.
Improvements in and relating to the Construction of Frames for
Velocipedes.
We, CHARLES MONTAGUE LINLEY of 16 Carmalt Gardens, Putney, in the
County of Surrey and JOHN BIGGS of 57 Lynette Avenue Clapham Common
Clapham in the County of Surrey, both Engineers do hereby declare the nature
of this invention and in what manner it is to be performed to be particularly
described and ascertained in and by the following statement :—
Our invention relates to an improvement in the construction of the junction and
other pieces in the frames of velocipedes which cannot be made out of the tube of
which the members of the frame are constructed and which at the present time are

page_text: either made out of drop stampings or malleable castings, and it has for its object,
increased strength, dispensing with the machining of the parts and therefore a
saving in first cost.
We attain this end by constructing these junction and other pieces of sheet
steel stampings, each piece being formed of two stampings which when rivetted
and brazed together form the desired part or piece.
The size and shape of these pieces will obviously vary according to the frame
for which they are intended, but it will be seen that by constructing these parts or
pieces in the manner herein before described they can be made as light as possible
being mere shells in many cases, and of the exact shape required, thus obviating the
necessity of any machining.
In order that our invention may be fully understood we append a drawing
hereto shewing the application of our invention to some of the parts of the well
known safety bicycle.
Referring to the drawing,
Figures 1, 2, 3 and 4 illustrate the construction of the slotted ends of the main
frame of a safety bicycle adapted to carry the axle of the driving wheel. Figures '1
and 2 being views in side and end elevation respectively of a blank stamped out of
sheet steel. Figure 3 a view in end elevation of a blank pressed or blocked up
to the required shape to form one half of the complete piece and, Figure 4 a' view
in plan of the complete piece formed by rivetting the two parts together.
Figures 5, 6, 7 and 8 illustrate the construction of a split socket, such as is used
to support the seat pillar, Figures 5 and 6 being views in elevation of the blank.
Figure 7 a view in elevation of the blank pressed or blocked to the desired shape
and, Figure 8 a view in elevation of the complete socket ready to be 'fixed to the
frame.
Figures 9 and 10 illustrate the construction of a crown for the back forks of a
safety bicycle the particular shape shewn being that used in conjunction with our
improved pedal-crank axle bearing bracket described in our Patent No. '2659
of 1891. Figure 9 being a view of one of the blanks stamped and pressed or
blocked into the desired shape to form one half of the crown and Figure 10'a view
of the crown complete.
It will be seen that by this construction all machining is avoided, as if the 'dies
are accurately made the parts will be produced of the exact finished size. The
parts adapted to be fixed to the tubular members of the frame may be made either
male or female as it is desired that the said tubular members should receive or be
received by the said parts. It will be understood that the two halves of each part
are identically alike except that in pieces of irregular shape they are right (and left
handed and that they are merely rivetted together for the purpose of holding them
together while they are fitted to the tubular members of the frame as they are
brazed together at the same time that the said tubular members are brazed to
the parts.
We do not bind ourselves to the exact parts or shapes therefor hereinbefore
described and illustrated by the accompanying drawing as they are only given by
way of illustration, our invention being applicable to all the parts of the frames of
velocipedes other than the. tubular members.
Having now particularly described and ascertained the nature of our said inven-
tion' and in what manner the same is to be performed wwe.declare that what we
claim is.
1. The improvements in the construction of the frames of velocipedes as herein-
before described.
2. The improved construction of the junction pieces used in the construction of
'frames for velocipedes as hereinbefore described.
3. Constructing the junction pieces and other parts other than the tubular
members used in the construction of the frames of velocipedes, out of two pieces

page_text: of sheet steel or other metal so stamped out and pressed or blocked up that when
two of them are rivetted or otherwise fixed together they form a piece of the
desired shape and size, as set forth.
