Improvements in and pertaining to the Framing of Velocipedes and
other Carriages.
We WILLIAM LEANNARD POOLE ALFRED STONE and ALEXANDER
ST. VINCENT TURQUAND all of 200 Blackstock Road Highbury in the County
of Middlesex Manufacturers do hereby declare the nature of this invention to be
as follows:—
It is always and in all cases needful that the framing of velocipedes and all other
carriages should be strong enough to withstand the strain that is to be put thereupon
and it is generally desirable that such framing should be as light as is compatible
with the provision of this needful strength. It is further at the present time.
considered to be a great advantage to make the framing of bicycles as narrow as
possible so that the feet when on the pedals shall not be far apart. The object of
our invention is so to construct the framing of velocipedes and other carriages as to
fulfil these conditions and all other ordinary requirements of the same.
To carry out this object we make the framing of any ordinary or other shape in
any customary or other style and of any desired size and strength and all the
members thereof or so many and such of these members as may be necessary or
expedient are made of a triangular shape in section and may be solid or as will be
generally advisable and particularly in and for velocipedes may be hollow.
When these members are hollow they may be made in any convenient and usual
or other manner. For example they may be drawn or cast or otherwise similarly
constructed. Again they may be made of a single piece of sheet metal which
could be longitudinally bent to produce the required triangular shape and the
edges thereof can overlap either at or near one of the angles or on one of the sides
and can be secured together by brazing or rivetting or otherwise. Again they
may be made of three flat strips of sheet metal which would form the three sides
of the triangularly shaped member which three strips could be joined together by
brazing or rivetting or otherwise by and through three external or internal angle
pieces which may preferably extend along the whole length of the same. Again
these angle pieces may constitute the member and the edges thereof could overlap
each other or be provided with butt straps and be joined by brazing or rivetting or
otherwise.
When these members are solid they may likewise be made in any convenient and
usual or other manner.
If the member is made of an equilateral triangular shape it is obvious that it
matters little or nothing how it is placed in the framing but when it is made of an
isosceles triangular shape and especially as is perhaps preferable of a flat isosceles
triangular shape it is most conveniently and suitably placed with its base in the
line of force or pressure. For example in a bicycle the two lower rear members of
the frame would preferably each be of a flat isosceles triangular shape in which
the base would be larger than the two sides and they would be placed in the
framing with these two bases facing each other.
The members so made can be joined together and can be provided with such
fittings and appliances and devices as is customary or as may be desired to complete
the framing for its destined use.

other Carriages.
We WILLIAM LEANNARD POOLE, ALFRED STONE, and ALEXANDER
ST. VINCENT TURQUAND all of 200 Blackstock Road Highbury in the County
of Middlesex Manufacturers 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 :-
It is always and in all cases needful that the framing of velocipedes and all other
carriages should be strong enough and rigid enough to bear the weight and to
withstand the strain that is to be put or that may be put thereupon and it is also
generally desirable that such framing should be as light as is compatible with the
provision of this needful strength and rigidity. It is further at the present time
considered to be a great advantage and excellence to make the framing of bicycles
as narrow as may be possible so that the feet when on the pedals shall not be far
apart.
Now the object of this our invention is so to construct and arrange the framing
of velocipedes and other carriages as to fulfil these conditions and all other
requirements of the same or such and so many of them as may be applicable in
each particular case.
In order the more clearly to explain this our invention and in what manner the
same is to be performed we refer to the accompanying drawing wherein Figure 1 is
an elevation of part of a dwarf or safety bicycle with a framing constructed and
arranged according to our invention and Figures 2, 3, 4, 5, 6, and 7, are sections
of this framing shewing various methods of constructing the same.
The framing of this bicycle is made in elevation of any ordinary or other shape
in any customary or other style and of any desired size and strength and all the
members thereof or so many and such of these members as may be necessary or
expedient are made of a triangular shape in section and may be solid or may be
hollow as will be generally advisable for purposes of lightness and perhaps also
even of strength and rigidity and therefore as will be particularly applicable in
and for velocipedes.
When these triangular members are solid they may be constructed in any
convenient and usual or other manner whether by casting or drawing or rolling or
otherwise and may be made of an equilateral or isosceles or other triangular shape
in section.
When again these triangular members are hollow they may likewise be constructed
in any convenient and usual or other manner and in the drawing we shew four of
such ordinary methods. These members may be drawn or cast or otherwise
similarly constructed in one piece as is shewn in Figures 2, 3, and 4. Again these
members may be constructed of a single piece of sheet metal as is shewn in
Figure 5 which would be longitudinally bent to produce the required triangular
shape and the edges of this piece can overlap each other it may be as is shewn at
or near one of the angles thereof or it may be on one of the sides thereof which
edges can be secured together by brazing or rivetting or otherwise. Again these
members may be constructed of three separate flat strips of sheet metal as is shewn
in Figure 6 which would form the three sides of the triangularly shaped member
which three strips could be joined together by brazing or rivetting or otherwise by
and through three external or internal angle pieces as is shewn which may preferably
extend along the whole length of the same or the adjacent edges of these strips
may overlap each other and be similarly secured together by brazing or rivetting
or otherwise. Also the angle pieces aforesaid may be enlarged and two of them
may constitute the member as is shewn in Figure 7 or it may be that three of them

page_text: could be similarly used and arranged accordingly and the adjacent edges of these
angle pieces could overlap each other as is shewn or could be provided with butt
straps and could be secured or joined together by brazing or rivetting or otherwise.
The hollow members likewise may be made of an equilateral or isosceles or other
triangular shape in section.
When the inember whether it be solid or hollow is made of an equilateral
triangular shape in section as is shewn in Figures 4, 5, 6, and 7, it is obvious that
it matters little or nothing how and in what position it is placed in the framing for
all its sides ought to be of equal strength but when it is made of an isosceles
triangular shape in section as is shewn in Figures 2, and 3, it is most conveniently
and suitably placed in the framing with its base in the line of the force or pressure
it will have to bear or sustain for this base ought to be the strongest side. For
example in the bicycle shewn in Figure 1 the two lower rear members A of the
framing would preferably each be made of a flat isosceles triangular shape as is
shewn in Figure 3 wherein the base would be larger than the two equal sides and
they would be placed in the framing as is shewn in this Figure 3 with these two
large bases facing each other by which arrangement "the tread" of this bicycle
would be rendered very narrow and the feet when on the pedals would not be far
apart while at the same time the large bases of these two members being in the
proper positions will render the same very strong and rigid. The front fork of
this bicycle could also preferably be made and arranged in the same manner.
Again in the bicycle shewn in Figure the two upper rear members B of the
framing could each be made of an high and narrow isosceles triangular shape as is.
shewn in Figure 2 wherein the base would be smaller than the two equal sides and
they could be placed in the framing as is shewn in this Figure 2 with these two
small bases facing each other by which arrangement also these two members will
be rendered very strong and rigid. The other members of the framing of this-
bicycle if and when they are of a triangular section may be made of such shapes
and arranged in the framing in such positions as may in each particular case be
desired or as may be appropriate to subserve the appointed purpose.
The members of the framing of this bicycle so made and arranged as is herein-
before described can be joined and connected together and can be provided with
such fittings and appliances and devices as is customary and convenient or as may
be necessary or desirable in each particular case to properly and duly complete the
framing for use in the ordinary manner for its destined purpose.
In the same or in a similar manner the framing of other velocipedes and of all
other carriages would be made and constructed and arranged as is customary and
appropriate or as may be applicable and convenient in each particular case and no.
further description or explanation is or can be needed.
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 :-
The improvements in and pertaining to the framing of velocipedes and other
carriages substantially as hereinbefore described and shewn in the accompanying
drawing.
