Improvements in Wheels, chiefly designed for Velocipedes.
I, HOSEA WAITE LIBBEY of 55 Rutland Square in the City of Boston, and
State of Massachusetts, United States of America, Physician, do hereby declare
the nature of my invention to be as follows :-
The object of my invention is to produce a duplex tread wheel particularly
applicable to velocipedes and the like, and the invention consists in a wheel having
two treads whereby it will be self-supporting in a perpendicular position.
The wheel consists of a hub, spokes and rim as in an ordinary velocipede tension
wheel. To the rim are secured Haring arms to which rims are attached adapted to
receive rubber tires, thus converting an ordinary wheel into a wheel with two tires,
To convert an ordinary velocipede into a wheel embodying my invention, the
rubber tire is removed, and to a portion of the rim are secured a series of arms,
these arms are at their centres formed with half round projections that fit into the
recesses of the rim of the ordinary wheel and are secured thereto by a bolt, and
the outer ends of the arms are formed with half round recessed pieces into which
are fitted rims that are secured thereto by screws or rivets. After these rims have
been secured to the arms, the remaining arms are slipped in between the rim of the
ordinary wheel and the rims and secured in the manner before described. After
all the arins are thus secured, rubber tires are sprung into the grooves in the outer
rims and the wheel is complete.
It will be seen that by this construction a duplex tread wheel is produced that
will stand perpendicularly of its own accord, which will be a great advantage for
bicycles as the rider can stop his machine and stand still without any danger of the
machine toppling over.
Although I have shown and described my invention applied to a tension wheel, it
is obvious that it could be applied to any description of wheel, and the outer rims
might be flat on their surface, and the rubber tires dispensed with if desired.
Dated this 6th day of March 1893.

Improvements in Wheels, chiefly designed for Velocipedes.
I, HOSEA WAITE LIBBEY of 55 Rutland Square in the City of Boston, and
State of Massachusetts, United States of America, Physician, do hereby declare
tho nature of my 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 my invention is to produce a duplex tread wheel particularly
applicable to velosipedes and the like, and the invention consists in a wheel having
two treads whereby it will be self-supporting in a perpendicular position.
Referring to the accompanying drawing :
Fig. 1 represents a perspective view of a tension wheel having two treads
according to my invention.
Fig. 2 represents a vertical section through the same, the hub and spokes being
removed.

Figs. 3 to 6 are detail views showing how the two trends are attached to the rim
of the wheel.
A, represents the hub, B, the spokes; and C, the rim of an ordinary velocipede
tension wheel. D, are arms secured to the rim C, and E, E, are rims attached to
the ends of the arms, F, F, are rubber tires sprung into the rims E.
To convert au ordinary velocipede wheel into a wheel embodying my invention,
the rubber tire is removed, and to a portion of the rim are secured sumo of the
arms D, these arms as shown in Figs. 3 and 4 are at their centres formed with half
round projections d, that fit into the recess of the rim C, and are secured thereto
by a bolt b, and the outer ends of the arms are formed with half round recessed
pieces d', into which are fitted rims E, E, that are secured thereto by screws or
rivets.
After the rims E, have thus been secured to these arms, the remaining arms
are slipped in between the rim C, and the rims E, and secured in the manner before
described. After all the arms D, are thus secured, rubber tires F, are sprung into
the grooves in the rims E, and the wheel is complete.
It will be seen that by this construction a duplex tread wheel is produced that
will stand perpendicularly of its own accord which will be a great advantage for
bicycles, as the rider can stop his machine and stand still without any danger ni
the machine toppling over.
In Fig. 5 I have shown the hollow space of the rim C, filled with a block d³,
and an arm D', secured thereto, so that the arms are formed without the rounded
projection d.
In Fig. 6 I have shown an arm D' secured to a wheel with a flat rim C'.
Although I have shown and described my invention applied to a tension wheel,
it is obvious that it could be applied to any description of wheel, and the rims E,
might be flat on their surface, and the rubber tires dispensed with if desired.
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 :
1. In combination with a wheel consisting of a hub and rim connected together
by spokes a series of arms secured to the periphory of said rim the ends of the arms
on each side having a rim or tire secured thereto substantially as set forth.
2. A wheel consisting of a hub, spokes and a central rim, arms secured to the
Baid ċentral rim, and projecting on each side, and an outer rim secured to the ends
of the arms on each side of the central rim substantially as set forth.
3. In combination with a tension wheel consisting of a hub A, spokes B, and
rim C, a series of arms D, each having at its centre a rounded projection d, to fit
into the rim C, and secured thereto by a bolt b, the outer ends of each arm having
a rounded recessed piece d', the rims E, secured thereon, and rubber tires F,
Bubstantially as set forth.
