Improvements in the Construction of Cycle, Motor Car, and other
Frames, and in the Parts of such Frames.
I, EDWIN TAYLOR, of 1, Alfred Street, Warstone Lane, Birmingham, in the County
of Warwick, Stamper and Piercer, do hereby declare the nature of my said
invention and in what mauuer the same is to be performed to be particularly
described and ascertained in and by the following statement :-
My invention has for its object improvemonts in the construction of cycle, motor
car, and other frames, and in the parts of such frames, so as to avoid in a great
measure the expense of drawing tubes from the solid and in forming the junctious
by brazing or other devices, so that such frames may be made securely in all thoir
parts and more cheaply than at present. My present mode of construction is
specially applicable to the construction of cyclo frames.
In order that my invention may be clearly understood and easily carried into
practical effect I have appended hereunto a double-sized sheet of drawings, upon
which I have illustrated examples of my improvements.
Figure 1 shows two pieces of tube formed according to my invention and joined
together at right angles.
Figure 2 is a part section showing how the two tubes are connected together.
Figure 3 shows the piece of tube B before it has been bent ready for joining to
the tube A.
Figure 4 is an end view of the tube B after it has been bent ready for joining to
the tube A.
Figure 5 is a modification of Figure 4.
Figure 6 is a modification of Figure 2.
Figure 7 is a cross section showing the first process in forming my tubes.
Figure 8 is a cross section of the tube complete.
Figure 9 is a modification of Figure 8.
In carrying my invention into practice I commence with a plain strip of shoet
steel or other tough metal and form it by suitable tools into the shape as shown at
Figure 7. I then bring the two halves of the circle together as shown at Figure 8
with the edges a' and a butting against each other. These edges are then secured
together by the rivets a³ as shown at Figuro 1. After these edges have been
rivetted together the seam may be bulged or pressed inwards and enclosed in the
interior of the tube as shown at Figure 8*. In some cases I may rivet the strip of
metal a' along this seam as shown at Figure 8, or I may turn the ends of the
edges a¹ and a³ inwards and then rivet them together as shown at Figure 9, or these
edges may be formed into a bead and rivetted together, or a bead or strip of metal
may be rivetted between them.
When joining or connecting the tube B with the tube A. I form a slit in the end
at the seamless side as shown at Figure 3 and then bend the two halves b and bª
with their edges butting against each other as shown at Figure 4 or overlapping as
shown at Figure 5. This end of the tube is then inserted between the seam of the
tube A as shown at Figure 2 and the ends a¹ and a³ are afterwards rivetted
rn

page_text: togethor, and the ends b¹ and may be rivetted to the tube A, thus joining or
securing the two tubes together as shown at Figure 1. In some cases may bend
the ends b' and be outwards at right angles or thereabouts to the main portion and
parallel with the tube A. These onds have the ridge & formed in the centre, which
Ats between and is rivotted to the seam or edges a¹ and a² as shown at Figure 6.
Or I may bend the ends b' and 6 in the same direction as shown at Figure 10 and
then rivet them in the interior of the tube A, or the ends b' and may be rivetted
around the exterior of the tube A. In some cases I may overlap the edges cl of tho
tube and rivet them together as shown at Figure 11, or I may form a shoulder on
the edge c² so that the edge c¹ will be flush with the outer circumference of the tubo
as shown at Figure 12.
In order to stiffen or strengthen the tubes A and B they may be fluted or
corrugated bofore they are formed into tubes.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
clain is :-
CLAIMS.
First In cycles, motor cars and other frames forming the tubular members of
such frames from a strip of sheet metal with longitudinally flanged members united
together by rivets and either with or without an intermediate or overlapping strip,
the seam being either left externally or bulged or pressed inwards substantially as
heroinbefore described and as shown upon the accompanying sheet of drawings.
Second: Forming tubes from a strip of sheet metal in the mannor substantially
as hereinbefore described and as shown at Figure 7.
Third :—Forming the junctions of tubes as claimed in the preceding claims by
slitting the end at the seamless side and then bending these ends into a circle eithor
flush with or overlapping each other and inserting them into the junction piece in
the manner substantially as heroin set forth and as shown upon the accompanying
sheet of drawings.
Fourth Forming the junctions of tubos as herein before claimed by slitting the
end at the seamless side and then bending these ends outwards and inserting them
into and rivotting them with the junction piece in the manner substantially as heroin
set forth and as shown upon the accompanying sheet of drawings.
:-
Fifth The improvements in the construction of cycle, motor car, and other
frames and in the parts of such framos substantially as herein set forth and as shown
upon the accompanying sheet of drawings.
