I, MOSE MAX TÜRKHEIMER, Via Lauzone 10, Milan, Italy, Manufacturer, do
hereby declare the nature of this invention to be as follows:-
The present invention relates to a bicycle folding up along the saddle pillar
and in which the two wheels occupy a position one above the other when the
machine is folded up, so that it can be conveniently carried on the back by means
of a sling or belt which can be attached to the frame when required for use.
By this arrangement the machine when folded up is of a handy size, without the
necessity of shortening the frame tubes below the usual size or making them
so as to fold up by means of hinges, whereby the machine would lose in strength
and power of resistance.
In carrying the invention into effect the frame lugs which connect the frame
tubes with the saddle pillar tube, instead of being brazed in as hitherto are
simply inserted loosely, while at the same time being secured against the
displacement.
Below the upper lug a socket is brazed, welded on, or otherwise fixed on to the
saddle pillar tube, which socket carries at the back a lug on which the back fork
stays are fitted.
The upper lug is provided at the back with a boss, in which a winged nut is
seated (which of course may also be arranged at the side or applied in some other
form) with a screw passing through a hole in the saddle pillar tube, and acting
when tightened up upon a flat spring.
This flat spring is brazed at its lower end to the inner side of the saddle pillar
tube, and on tightening the nut aforesaid presses against the flat side of the saddle
pillar tube, so that the latter is held perfectly tight. The same arrangement
being also provided on the lower lug, the frame can be fixed in the position,
by tightening up the winged nuts so that it is absolutely rigid.
The handle-bar of such a folding bicycle is arranged so as to turn in the known
manner so that it will lie up quite close against the side of the frame and not
project in an embarrassing manner when the machine is folded up.
Either the lower or the upper lug is provided with a slot or opening, into which
the bent end of a piece of metal, fastened to the tube, projects so as to hold the
frame in its position for the time being and fix it in the proper position.
Instead of the bent piece of metal last referred to, a pin attached to the saddle
pillar tube, and borne in the slot, may be provided, or the lugs and saddle tube
may bear on each other after the fashion of an easel or strut, whereby the desired
support of the frame at certain points will likewise be obtained.
The frame is provided with hooks or eyes, to which belts or slings can be
attached so that the cycle, when folded up may at once be strapped on the back
and carried in this way. The sling may also be fastened direct to the frame, or in
some other fashion.

page_text: I, MOSE MAX TÜRKHEIMER, of Via Lauzone 10, Milan, Italy, Manufacturer, 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 any by the following
statement:
The present invention relates to a bicycle which can be folded up along the
saddle-pillar tube, and in which the two wheels lie one over the other when the
machine is folded, so that it can be conveniently carried on the back by means of a
strap which can be attached to the frame.
By means of this arrangement the machine when folded is of a very handy size,
without having any of the frame-tubes shortened in any way below their usual
length, or made to fold into a smaller compass by means of joints whereby the
machine would lose in rigidity and strength.
In the annexed drawings the frame of such a machine is shown in
Fig. 1, in elevation, ready for use.
Fig. 2, shows the frame folded up.
Fig. 3, is a longitudinal section through the saddle-pillar tube.
Fig. 4, is a cross section through the same.
Figs. 5, 6, 7 and 8 are details of variations.
The frame connection parts or lugs 1 and 2, joining the frame tubes 3 and 4 to
the saddle pillar tube 5, are loosely inserted and at the same time secured against
displacement. Underneath the upper lug 1, a socket or short piece of tube 6
is fixed to the saddle pillar tube 5; this part 6 is fitted behind, with a lobe 7 on
which the back-fork stays 8 are arranged.
The frame connection parts or lugs 1 and 2 are each provided with a nave-
like boss, or strengthening, 1", and 2", respectively, in which a winged nut 9 is
seated, which of course might also be arranged laterally, or in a different form,
and which when tightened up will clamp the saddle-pillar tube 5 immoveably.
As Fig. 4 shows, the saddle-pillar tube 5 is provided with a flat side 5", against
which the winged nuts 9 are pressed, thus ensuring that the various parts of the
frame are held fast absolutely and reliably in position, during the use of the
machine. The same purpose may also be ensured by other means, for instance,
by an eccentric locking arrangement 17 (Fig. 8), which consists of a pivotted
eccentric disc which by raising or lowering the lever forming part thereof is caused
to catch into the cavity of a locking boss or box.
The handle-bar of such a cycle provided with a folded frame is constructed
so as to revolve in a known manner, so that it can be placed in such a position as
not to project obstructively when the cycle is folded.
In the upper or lower one of the connections or lugs 1 and 2 a slot-like notch 11
is provided, into which the bent-over end 12 of a piece of metal attached to the
saddle-pillar tube catches, whereby the frame is stayed in its correct terminal
positions, Fig. 5.
Instead of the bent-over piece of metal 13 a pin 16 attached to the saddle-pillar
tube 5 and guided in the slot-like notch 11, may also be provided. (Fig. 6).
According to Fig. 7, the same purpose may also be obtained by arranging the
parts 1, 2 and 5, and 6 respectively, so as to catch against each other by a step-like
arrangement whereby likewise the requisite stay or support of the parts of the
frame in their terminal positions is assured.
The frame is fitted with hooks or eyes, 14, 15, into which slings may be fixed so
that the cycle when folded up can be strapped on the back and carried. Of

page_text: course, the slings or straps may also be fastened in some other way, for instance
direct to the frame.
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 claim is: :-
1. Cycle characterized by the circumstance that the frame can be folded up
along the saddle-pillar tube 5 so that the two wheels are superposed on each other
when the machine is folded, which end is attained with the aid of frame connection
parts or lugs 1 and 2 fixed to the frame tube 3 and 4 and loosely clasping the
saddle-pillar tube 5, for the purpose of enabling the rider to carry the machine
conveniently on his back by means of slings attached to the frame.
2. A form of execution of the cycle claimed under 1, in which the frame con-
nections or lugs 1 and 2 can be rigidly fixed to the saddle-pillar tube 5 in the two
terminal positions, by means of clamping arrangements, for instance clamp-
screws 9 or eccentric locking arrangements (Fig. 8).
3. A form of execution of the cycle claimed under 1, in which the frame
connections or lugs 1 and 2, and the saddle-pillar tube 5, are stayed in their
terminal positions by the said parts 1, 2 and 5 catching into each other by a step-
like arrangement (Fig. 7) or by a piece of metal 13 with a bent-over end, or a
pin 16, on the one part, being guided in a slot-like incision 11 on the other part.
