Improvements in and connected with Folding Cycles.
of
I, ALFRED WILLIAM TURNER, Mechanical Engineer and Patent Attorney, of
Cobden Buildings, 67A, Corporation Street, Birmingham, in the County of
Warwick, a communication from Eerste Nederlandsche Rijivielfabriek,"
Deventer, Holland, do hereby declare the nature of this invention to be as
follows:-
This invention consists in constructing a cycle in the new and improved manner
hereinafter described.
I provide a folding-joint formed from two extra tubes carried across the cycle-
frame at the dividing points, such pair of tubes being connected to the frame on
both sides of the dividing point and being hinged together, the hinged parts being
secured together when the cycle is in the extended-out usable position by means
of a bolt or rod or by means of bolts or rods taking into bayonet slots provided
in the hinged connecting parts.
The front part of the frame which carries the front wheel or wheels folds over
the back part of the frame thereby carrying over the front wheel or wheels to
lay on top of the back wheel or wheels forming several layers of wheels and
framing, the whole ocupying but a small space and forming a pack of convenient
size to be strapped to the back of a soldier on the march, or onto the back of any
other person to whom the conveying of a cycle from place to place would be a
convenience and an advantage.
By the adoption of my folding cycle, transit by rail and by sea-going vessel can
be better provided for than by the ordinary method of packing cycles, because
my improved folded cycles will pack closely together in barrels, crates, cases,
and the like.

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention has for its object the construction of a folding cycle so arranged
that one portion of the frame can be folded over the other portion of the frame
to thereby convert the cycle into a form suitable for packing within a small space
or for carrying on the back of a soldier or other traveller.
This invention consists in constructing a cycle in the new and improved manner
hereinafter described.
I will now proceed to describe with reference to the accompanying drawings
the manner in which my invention is constructed and used, similar letters refer
to similar figures throughout the several views.
Figure represents a side view of the folding frame in its bolted together
usable position.
Figure 2 represents an end view of Figure 1.
Figure 3 represents a plan of Figure 1.
Figure 4 represents an unfolded side view of the upper part of folding tubes
shewing the upper hinge.
Figure 5 represents an end view of Figure 4 viewed from the left.
Figure 6 represents an unfolded side view of the lower part of folding tubes
shewing the lower hinge.
Figure 7 represents a view of Figure 6 after the frame has been folded over.
Figure 8 represents an horizontal sectional plan view of Figure 4 on line A, B.
Figure 9 represents a detached plan of the hinge shewn at Figure 8.
Figure 10 represents a plan of Figure 4.
Figure 11 represents an end view of Figure 7, viewed from the left.
Figure 12 represents a plan of Figure 7 on the line C, D.
Figure 13 represents an enlarged side view of lower hinge and tubes, partly
folded so as to present to view the bolt and guide frame wherein the bolt locks.
Figure 14 represents a sectional plan of Figure 13 on the line E, F, shewing
the guide-frame with the bolt in its locked position.
Figure 15 represents a similar view to Figure 14 with the bolt in its unlocked
position.
Figure 16 represents a detailed view of the lower part of member B moved into
position so as to present a full side view of the guide-frame K.
In carrying out my invention I provide a folding-joint formed from two extra
tubes, rods, bars or equivalent members such new members being carried across
the frame on both sides of the dividing point as clearly shewn at Figure 1; the
tube or member A is secured permanently to the framing and the other tube or
member B is hinged to A so that the triangular section marked C will fold over
at the dividing point D, the hinged parts A and B being secured together when
the cycle-frame is in the extended usable position by means of the securing-bolts E
and E which take into bolt-holes formed in the receiving-lugs F and F of the
hinge-joint and also into the bolt-holes formed in the entering lugs G and G¹ of
the hinge-joints.
I provide a handle H and connecting-rod J, the connecting-rod is provided with
a knob a or with some other equivalent projection to which is secured the
handle H; Inext provide the upper securing-bolt E and the lower securing-bolt E',
the securing bolts are provided with crank-heads b and b¹ pierced to receive the con-
necting rod J, the securing-bolts being fastened to the connecting-rod J by means
of the set-pins c and c¹ or by other equivalent fastenments.
To the folding tube or member B just above the hinge-joint secure the guide-
frame K; the action of the bolt-head 6 within the guide-frame K is somewhat
similar to the action of a bayonet fastenment; the bolt-head 61 slides vertically up
and down between the vertical bars d and e of the guide-frame K..
When the frame is extended in the usable position as shewn at Figure 1 and
the entering lugs G and G¹ turned in between their receiving lugs, the user of the

page_text: machine would rotate the handle H so as to move the connecting-rod J and to
also turn the bolt-head 6' out of the upper supporting passage between f and g,
the bolt-head would then slide downwards within the space between d and e
until it reached the lower inset space between the bars h and j, the handle would
then be partly rotated and the bolt-head & thereby turned into the lower inset
space between the bars h and j, thus locking the lower bolt 13 securely and also
locking the upper bolt E from rising.
When the bolt E is about to be raised to disconnect the tubes or members A
and B ready for folding over, the rider lifts the handle H thereby drawing up the
connecting-rod J and lifting the bolts E and E¹ out of their entering lugs & and GI
and when the head b¹ of the lower bolt reaches the upper passage formed in the
guide-frame K the handle is partly rotated to turn the connecting-rod J and to
also turn the bolts E and E¹, the head b' of the bolt E¹ then passes between the
guide-frame bars f and g and is supported on the bar f.
The triangular front part C of my folding frame which carries the fork and
front wheel or wheels folds over the back part of the frame at the dividing point D
shewn at Figure 1 thereby carrying over the front wheel or wheels to lay on top
of the back wheel or wheels forming several layers of wheels and framing, the
whole occupying but a small space and forming a pack of convenient size to be
strapped to the back of a soldier on the march, or onto the back of any other
person to whoom the conveying of a cycle from place to place would be a con-
venience and an advantage.
By the adoption of my folding cycle, transit by rail and by sea going vessel can
be better provided for than by the ordinary method of packing cycles, because my
improved folded cycles will pack closely together in barrels, crates, cases, and
the like.
My improved folding cycle also affords facilities for storing in a dwelling house
in such a manner as to occupy but a small space.
Instead of connecting the extra tubes or members A and B in the vertical
position shewn at Figure 1 I prefer in some cases to connect the new members A
and B in an angular position which may be parallel (or otherwise) with the
permanent frame tube L, by so doing the folding over part would be of greater
dimensions than represented at C Figure 1.
Having now particularly described and ascertained the nature of my said
invention and the manner in which the same is to be performed, I declare that
what I claim is:-
1st. A folding-cycle the folding-joint of which is produced by the introduction
of two extra tubes, rods, bars or equivalent folding-members carried across the
frame and secured thereto on both sides of the dividing point, the folding-members
being hinged to each other so that one portion of the cycle-frame can be folded
over the other portion, as illustrated and described.
2nd. In a folding-cycle the providing of securing-bolts passing through the
entering and receiving lugs of the folding-members, for the purpose of securing
the cycle-frame in the extended unfolded usable position, as illustrated and
described in relation to E and E¹ Figure 2.
3rd. In a folding-cycle the providing of a guide-frame bayonet-fastenment for
the purpose of locking the securing-bolts after they have been slidden into the
bolting position, as illustrated and described in relation to d e f g h and j Figures 2
11 13 14 and 16.
