Applicable for Bicycles.
JOHN TOY Meneage Street Helston Cornwall Iron & Brass Founder, do hereby
declare the nature of this invention to be as follows:-
1st. An improved made back bone and forks for the hind or back wheel which I
make out of one piece of solid drawn weldless steel tube (or other preferred
material).
2nd. An improved made fork and post or head for the front wheel also made out of
one piece of solid drawn weldless steel tube (or other preferred material).
This invention refers firstly to an improved made back-bone and forks for the
hind or back wheel.
Secondly. To an improved made fork and post or head for the front wheel.
According to the first part of my invention I make the back-bone (which is the
part of the machine that connects the forks of the front wheel with the forks of the
bind or back wheel) and forks (is that part of the machine in the lower ends of which
the wheel is secured) of the hind or back wheel out of one piece of solid drawn
weldless steel tube (or other preferred material) instead of three or more pieces which
is the present adopted plan. The advantages I claim for my method are:-
1st. An increased amount of strength as it is found from experience that at the
place where the steel back-bone and forks for the hind wheel are joined together in
three or more pieces by the process known as Brazing, that this Brazing weakens the
nature of the steel tubes and so causes breakages. This process is entirely avoided
by my method for reasons described above.
2nd. A reduction in weight of the back-bone and forks as entirely doing away
with the connections required for putting the three or more pieces together.
According to the second part of my invention of an improved made fork and post
or head for the front wheel, I claim for it the same advantages as stated and fully
described in relation to the first part of my invention of the back bone and forks for
the hind wheel.

Having thus described the nature of my invention and the manner of performing
the same, I would have it understood that I claim as my invention in Bicycles &
Tricycles
First. An improved made back bone and forks for the hind or back wheel, substan-
tially as described in respect to Figures, 2, and, 1.
Second. An improved made forks and post or head for the front wheel, substan-
tially as described in respect to Figures, 4, and, 3.

Applicable for Bicycles.
JOHN TOY Brass & Iron Founder Helston Cornwall do hereby declare the nature
of my invention for IMPROVEMENTS IN BICYCLES & TRICYCLES and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This invention refers firstly-To an improved made Back-bone and forks for the
hind or back wheel.
Secondly To an improved made fork for the front wheel with the post or head.
Thirdly To an improved made saddle post and down piece. Each of these above
named articles forming parts of a Bicycle Frame.
According to the first part of my invention I make the Backbone (which is the
part of the machine that connects the forks of the front wheel with the forks of the
hind wheel) and forks (is that part of the machine in the lower ends of which
the wheel is secured) for the hind wheel out of one piece of steel tube (or other
preferred material) instead of three pieces which is the present adopted plan. The
advantages derived from this method of making each of the aforesaid parts out of
one piece of tube are :-
1st. An increased amount of strength as it is found from experience that at the
place where the steel back-bone and forks for the hind wheel are joined together by
the process known as Brazing, that the heat required to perform this brazed joint
weakens the nature of the steel and so causes breakages. This process is entirely
avoided by my method for reasons described above.
2nd. A reduction in weight as it entirely does away with the connections required
for putting the three or more pieces together.
According to the second part of my invention of an improved made Fork for the
front wheel with the post or head and also to the third part, of an improved made
saddle post and down piece with a hole through the centre at right angles and
sufficiently large to pass over the backbone; the same advantages are derived from
making each of these two parts out of one piece of steel tube as are stated in
relation to the first part of my invention for Backbone and Forks for the Hind
wheel.
In order that my said Invention may be most fully understood and readily carried
into effect I will proceed to describe the Drawings hereunto annexed.
DECRETION
Figure 1 is a perspective view showing the Back-bone, a, and Forks, c, for the
5 hind wheel, with the saddle post, b, and down piece, 6 I, in its position on the
Backbone, a.
and hind fork, c.
Figure, 2, is a longitudinal section of the Backbone, a,
The Backbone, a, is secured to the post or head D of the forks E for the front

page_text: wheel by means of a neck, having two pointed ends, securely fixed into the front end,
of the backbone with the pointed ends of the neck working into centres securely
fixed on to the post or head & regulated by a screw on the top. The hind wheel is
secured in the ends of Fork, c.
Figure, 3, is a perspective view of the front forks, E, with the post or head, D.
On the top of the post or head D, are fixed the Handles by which the Bicycle is
steered and the wheel is secured into the lower ends of the Front fork E by means
of a bolt passing through them.
Figure, 4, is a vertical section of the forks E for the front wheel with the post
or head, D.
Figure, 5, is a vertical section of the saddle post, b, and down piece, 6 I, showing
the hole, F, through which the backbone passes.
The spill which carries the saddle is firmly held in the saddle post, b, by a screwed
loop and is lowered or heightened as the case demands, and the bearings with cranks
by which the Bicycle is propelled are fixed into the lower end of the down
piece, b, I.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare what I
claim is
First The Backbone and forks for the hind wheel made out of one piece of
preferred Steel Tube substantially as described and with reference to Figures 1 and 2
of the accompanying drawings.
Second The Forks for the front wheel with post or head made out of one piece
of preferred Steel Tube substantially as described and with reference to Figures 3
and 4 of the accompanying drawings.
Third The saddle post and down picce made out of one piece of preferred Steel
Tube substantially as described and with reference to Figures 1 and 5 of the accom-
panying drawings. This part of my invention I claim only in combination with the
other parts.
