I, JOHN CLARENCE, GARVEY of Erlanger, County of Kenton and State of
Kentucky, U.S.A., Mechanic, 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 and by the following statement :-
The object of this invention is to provide an adjustable and collapsible attachment
for safety bicycles which will adapt them for riding on railways.
In the accompanying drawing

invention. Fig. 2 a plan view of the same.

the same.

Fig. 8 a side elevation of a bicycle with the attachment or device folded thereon
for travelling over ordinary roads.
Fig. 9 a diagrammatic view of the attachment.
Secured to the front fork a of a bicycle A is a U shaped frame B. The frame
may be pirotted to the axle; but a preferred form is shewn in Figs. 5 and 6, in
which a notched bar a', having a curved slot a', enlargel at one end, is secured to
the front fork. Passing through the end of the U shaped frame and through this
slot is a clamping bolt a, having an enlarged end a. This head is of the same
size as the enlarged end of the slot and is adapted to pass therethrough.
hook a is pivotted to bar a' and is adapted to take over clamping bolt a'.
this arrangement the U shaped frame may be quickly removed from or placed
upon the wheel.
A
By
To place the U shaped frame upon the bicycle the headed end of clamping
bolt a is passed through enlarged end of slot a². The bolt is then slipped forward
until hook a can take thereover. The clamping bolt is then tightened and the
U shaped frame secured to the wheel. To remove, the reverse operation is gone
through.
The Ushaped frame is adapted to swing on its pivot into an upright position
and be held in this position by means of a clip strap a, taking around the head of
the wheel and adapted to engage and grip a strip b, secured to the U shaped frame.
Pivotally secured to the closed end of this U shaped frame is a second U shaped
frame B', adapted to slide transversely, relatively to frame B, and carrying a
flanged wheel C, adapted to rest on one rail of a railway track. The notched bar a
prevents the U shaped frame B from swinging into a position underneath the
front wheel, should the bicycle be raised when the U shaped frame is in its lower
position.
Pivotally secured to the rear of the bicycle is a U shaped frame D, which takes
around the wheel and carries a second U shaped frame D', pivotally secured
thereto, in the same manner as frame B', and carrying a flanged wheel E. The
U shaped frame D is adapted to swing on its pivot into an upright position, as
shewn in Fig. 8, and be held thus by means of a spring F, or into the position

page_text: suewo in rig. 1 where Hanged wheel E is resting on one rail of a railway
track.
Secured to frame B' by means of a hinge g is a jointed bar G carrying at its
outer end a link g' pivotally, secured thereto. Pivotted to the other end of link g¹
at is a slotted bar H, carrying at its outer end a flanged wheel h, which is
adapted to travel upon the rail of a railway track. Secured to the upper rod
of bicycle A is a rectangular block a', to which is secured a brace rod J having
its outer end pivotted to slotted bar Hat ' and having a length varying mechanism
therein. In Figs. 1, 2, and 9 is shewn this space varying mechanism as consisting
of an ordinary turnbuckle; but in Fig. 7 is shewn a modification in which K is a
rack bar adapted to slide in a dovetailed groove as in block a. A pinion L
adapted to be actuated by a worm M, actuates the rack bar K: A hand wheel N
is mounted on a shaft parallel with worm M and through connecting gearing is
adapted to actuate the worm. The upper end of brace rod J is secured to rack
bar K. Block a' may be made removable from the frame of the bicycle.
Hinged to the frame D' is a jointed brace rod O having its outer end pivotted
to slotted bar H at h¹.
Pivotted to brace rods G and O is a slotted bar P taking across slotted bar H.
A binding bolt Q is passed through the slots in bars P and H and is adapted to
hold the two firmly together. This arrangement of braces enables the flanged
wheels to be set in any position to accommodate them to different gauges of rail-
roads or to different angles of inclination. The brace rod O may if desirable be
strengthened by a brace rod O' attached in any couvenient manner.
Secured to the bottom frame, near the center thereof, is a pair of prongs b¹,
pivotally fixed at to form a U shaped arm, and is then fastened to the frame by
means of a nut and a bolt 4, the bolt projecting somewhat beyond the nut to act
as a rest for the prongs, when they are folded back. The prongs are to prevent
turning of the front wheel, while being removed or transferred to the track, and
when on the roadway may be folded back to bolt 6 whenever desired.
In Fig. 9 is shewn in full lines the preferable position of the flanged wheel h
where it is practically opposite Hanged wheel C. In dotted lines the flanged wheel
is shewn thrown into a position practically opposite the saddle of the bicycle. By
loosening the different bolts and nuts the flanged wheel may be moved along
the straight line between its position shewn in full line and that shewn in dotted
lines, or to move the flanged wheel inward as shewn in dotted lines. By loosening
binding bolt Q slotted bar H may be swung on pivot h and clamped at any
required angle.
In Fig. 1 is shewn in dotted lines a possible position of the flanged wheels, in
which the front bicycle wheel leads the flanged wheel C. When the bicycle is
ridden with the flanged wheels in this position, the flanged wheel E is carried by
an extensible U shaped frame and is thrown to a position a few feet in the rear of
the rear wheel.
In riding I find that it is practically impossible to pass around a curve without
some means of tilting the wheel to accommodate it to curves.
For this purpose
I interpose in the length of brace rod J a space varying mechanism which can be
operated manually while riding, so as to tilt the bicycle to one side or the other, as
may be desired. With the ordinary turnbuckle, rod J is lengthened and shortened,
and by the mechanism shewn in Fig. 7 the rod remains the same, but its upper
end being secured to the rack bar K which is movable relatively to the bicycle
frame, the distance between flanged wheel and the upper part of the bicycle
frame may be lengthened or shortened and the bicycle tilted to one side or the
other. I sometimes mount a level a' (Fig. 2) over the wheel, so as to judge
the angle of inclination of the wheel.
All the brace rods are made in sections, as shewn in Fig. 4, and are secured
together by central plug R. The parts are all made detachable and may be folded
into the position shewn in Fig. 8, where the brace rods are all placed in a satchel
supported within the frame of the bicycle. The flanged wheel h is placed on a

page_text: carrier above the handle bars. It will thus be seen that by so arranging the parts,
an ordinary bicycle may be converted into a railway bicycle, which may be
accommodated to all conditions of gauge and curvature.
Having now particularly described and ascertained the nature of my said inven--
tion and in what manner the same is to be performed, I declare that what I
claim is :-
