IMPROVEMENTS BICYCLES AND TRICYCLES
Year: 1884

page_text: I WILLIAM ANDREWS Engineer Victoria Works Victoria Road Aston Warwick-
shire do hereby declare the nature of my invention for IMPROVEMENTS
BICYCLES AND TRICYCLES to be as follows:-
IN
This Invention consists of improvements in the formation of the Head and
Handle-bar of Bicycles and Tricycles whereby the handle-bar can be fixed or
removed at will, thus greatly reducing the cost of packing and also the risk of
breakage during transit, at the same time offering great facility to the owners of
machines in replacing broken or bent handle-bars at their own homes without the
need of skilled labour.
The Head is made in the following manner A parallel or tapered mettal hollow
pillar of suitable and convenient dimentions which may be about five inches in
length by about one inch and a quarter diameter where parallel, more or less and
about one inch and a quarter diameter at the top by about one inch and a half
diameter at the base where tapered, more or less, is shaped at the small or top end
in the manner hereinunder described.
Looking at the front of the head on its vertical plane a lug or parrallelogram is
formed level with the top, extending downwards about one inch and a half more
or less, the length from left to right being about two inches more or less.
The beforementioned parallelogram is slotted to a depth of about three eighths
of an inch and a width of about one inch more or less, thus leaving a flange of one
fourth of an inch in thickness more or less at the top edge of the slot and also at
the bottom edge of the said slot.
The bottom face of the said slot which is about one inch wide as hereinbefore
mentioned can be made either perfectly flat or of a concave or other suitable
shape.
Two tapped holes are made through the beforementioned flat or concave face of
the lug or parallelogram about three eighths of an inch diameter by about one inch
and three eighths from centre to centre more or less.

page_text: Handlebars of various lengths and dimentions are then made in such a manner
that the centre of each handlebar is formed into a suitable shape to fit in the
beforementioned slot in the lug or parallelogram.
Two clearance holes are made in the part of the handlebar that fits in the
beforementioned slot, corresponding with the holes in the said slot.
The handlebar is then placed in the slot of parallelogram suitable pins are then
passed through the clearance holes in the handlebar into the tapped holes in the
parallelogram and screwed up tightly, thus forming a compact and rigid attachment
and connection by means of which handlebars of any pattern and size can be fixed
to Bicycles or Tricycles and removed at will by inexperienced persons.

page_text: WILLIAM ANDREWS Engineer Victoria Works, Victoria Road in the County of
Warwickshire do hereby declare the nature of my invention for IMPROVEMENTS
IN BICYCLES AND 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 consists of improvements in the formation of the Head and
Handle-bar of Bicycles and Tricycles whereby the handle-bar can be fixed or
removed at will, thus greatly reducing the cost of packing and also the risk of
breakage during transit at the same time offering great facility to the owners of
machines in replacing broken or bent handle bars at their own homes without the
need of skilled labour.
The head is made in the following manner, A parallel or tapered metal hollow
pillar, of suitable and convenient dimentions which may be about 5 inches in
length by about one in and a quarter inches diameter where parallel more or less
and about one inch and a quarter diameter at the top by about one inch and a half
diameter at the base where tapered, more or less is shaped at the small or top end
in the manner hereinunder described.
Looking at the front of the head on its vertical plane a lug or parralelogram is.
formed level with the top, extending downwards about one inch and a half more
or less, the length from left to right being about two inches more or less.
The beforementioned parallelogram is slotted to a depth of about three eights of
an inch and a width of about one inch more or less, thus leaving a flange of one
fourth of an inch in thickness, more or less at the top edge of the slot and also at
the bottom edge of the said slot The bottom face of the said alot which is about
one inch wide as herein before mentioned, can be made either perfectly flat or of &
concave or other suitable shape.
Two tapped holes are made through the beforementioned flat or concave face of
the lug or parallelogram about three eights of an inch diameter by about one inch
and three eights from centre to centre more or less.
Handle bars of various lengths and dimentions are then made in such a manner
that the centre of each handle bar is formed into a suitable shape to fit in the
beforementioned slot in the lug or parallelogram.
Two clearance holes are made in the part of the handle bar that fits in the.
beforementioned alot corresponding with the holes in the said slot.
The handle bar is then placed in the slot of parallelogram, suitable pins are then
passed through the clearance holes in the handle bar, into the tapped holes in the
parrallelogram and screwed up tightly, thus forming a compact rigid attachment
and connection by means of which handle bars of any pattern and size can be fixed
to Bicycles or Tricycles and removed at will by inexperienced persons.
I will now proceed to describe with reference to the accompanying drawings the
manner in which my invention is constructed and carried out.
-
Figure 1 is an elevation of the head of a Bicycle or Tricycle, shewing the
handle-bar fixed in, and, screwed to, the Head.
Figure 2 is a plan of Fig 1.

page_text: Figure 11 shews the handle bar central part formed to fit on the projection of
parallelogram.
Figure 12 shews the parallelogram formed similar to figure 4-excepting that
the flange is below.the top.
Figure 13 shews the handle bar central piece formed to fit in the slot C of
figure 12. In carrying out my invention I by preference form the parallelogram
and handle bar as represented at Figures 1-2-3. A is the lug or parallelogram.
Bis the central part of handle bar, formed of suitable shape to fit in the slot of lug
or parallelogram.
is the slot or recessed part formed to receive the central part of handle-bar.
D shews part of the rounded ends of handle-bar the remainder being cut off. E are
the pins that fasten the handle bar to the head.
Figures 12 and 13 shew a similar arrangement to that represented in
combination at Figure 3, excepting that the upper flange is not level with the
top of head.
Figures 10 and 11 shew the projection on the lug and the recess in the central
part of handle-bar answering the same purpose as Figures 12 and 13.
i
Figures 10-11-12 and 13 would be adopted where lightness is a consideration,
less metal being needed than in Figure 3.
What I consider to constitute the escential part of my invention is the fact of
making Bicycles or Tricycles with movable handle-bars.
I do not attach any special importance to the modifications numbered 6—7—
8-9-10-11 which are some of the "Other suitable shapes" spoken of in my
provisional specification, but having now fully 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
"
1 The making of Bicycles or Tricycles with movable handle bars, the handle
bar being attached to the head of Bicycle or Tricycle in the manner illustrated at
Figures 1-2-3-12 & 13.
2nd The making of the head of a bicycle or tricycle with a parallelogram or lug
formed to receive the centre part of the handle-bar.
'
3rd The making of handle bars for bicycles or tricycles with the central part
formed to fit interchangeably in or on a lug or projection formed in or on the heads
of bicycles or tricycles.
