An Improved Tricycle for Converting into a Bicycle.
1, GEORGE HERBERT TEAGUE 2 Lung Arno Acciajoli Florence Italy, Artist,
do hereby declare the nature of this invention to be as follows:-
-
This invention relates to an improved tricycle for converting into a bicycle when
required and the same is carried out as follows. The frame carrying the two
rear wheels of the tricycle is removable being attached to the frame by suitable
bolts or nuts. By removing the said nuts the two rear wheels may be removed
and a frame carrying the one wheel of the bicycle type is attached, by bolts or
nuts in place of the two rear wheels. The chain driving the two rear wheels is
removed and placed around a spur wheel attached to the bicycle wheel carried in
the frame aforesaid.
The hub carrying the wheels of the bicycle or tricycle has a toothed end or
projection which engages in teeth or an aperture in the collar attached to the
driving spindle, said hub sliding on a rod which runs through the axle or bearing
upon which the wheels run.. By this arrangement the ball bearings of the wheels
are not interfered with as the hub and bearings are removed together from the
axle or spindle on which it runs when required.

An Improved Tricycle for Converting into a Bicycle.
I, GEORGE HERBERT TEAGUE 2 Lung Arno Acciajoli Florence Italy, Artist,
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 :-
This invention relates to an improved tricycle for converting into a bicycle when
required and the same is carried out as follows:-The frame carrying the two
rear wheels of the tricycle is removeable being attached to the frame of the machine
by suitable bolts or nuts. By removing the said nuts the two rear wheels may be
removed and a frame carrying the one wheel of the bicycle type is attached by
bolts or nuts in place of the two rear wheels. The chain driving the two rear
wheels is removed and placed around a spur wheel attached to the bicycle wheel
carried in the frame aforesaid. In order that my invention may be fully under-
stood, I will now refer to the annexed drawings in which.

Figure 7 side elevation of jaw ends for use with my invention.
Figure 8 side elevation of a modified form of same.
Referring to Figures 1. 2. & 3, e are supports connected at the point a by a bolt
and nuts to the frame of the machine o and at 6 to the rod m which is connected
by the rods or bars & to the crank bracket or bearing o', through the medium of
the rods or bars o². d is the axle which carries wheels at each end when for use as
a tricycle, m being the supporting bar or bridge for same, that is carrying and
supporting the axle d in suitable bearings as at 63 which carries the side wheels of
the tricycle. This frame can be removed by removing the bolts a and b¹; and the
frame n, n, which carries the bicycle wheel is connected by the bolts a and b¹ to
the frame of the machine o as before which carries the seat or saddle.
In Figures 5 & 6, the hub s carrying a wheel is shown attached to the axle of a
tricycle, that is the hub s is bolted to the flanger which is attached to or carried
by the shaft or axle d. This axle d carries wheels at each end so as to form a
tricycle. It will be seen that the spindle g may be adjusted in the hub s' so as to
project a sufficient distance at each end and engage in the ends of the frames n, n,
or bearings when used as a bicycle being secured in position in that case by nuts t
or other convenient means. When desired the hub carrying the wheel may be
bolted to the flange r, the spindle qt being screwed or passed through the caps 2
and then into the flange r, the hub being bolted by bolts g to the flange r so that
tne hub used in the bicycle frame n, n, may if desired be used in the tricycle
frame. In the case of a bicycle the spindle q' is adjusted in the hub so that its
ends are secured in the bicycle frame n, n, by nuts t.
In Figures 7 & 8 the bearings b¹ slide in the forks 9 having a screw bolt
which is movably attached to same being adjusted by the nuts i aud i having in
Figures 7 and 8 locking nuts s and respectively for the purpose of adjusting the
tension of the chain. In Figure 7 a nut 3 having a flange k¹ enters a slot k
in the fork g. j, j, are projections on the ends of the fork g, and a nut having
a circular space or recess in which the projections ; engage is screwed upon the
bolt thus preventing the ends or jaws of the fork g from spreading, s being a
lock nut for securing the nut 3 in position.
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 a convertible tricycle a detachable frame which carries the two tricycle
wheels being secured to the frame of the machine by bolts or the like in
combination with a frame carrying the bicycle wheel which may be attached to
the frame of the machine by bolts or the like, said wheels being adjustable in
forked bearings by means of a bolt and lock nuts, one of the nuts having a circula
space or recess in which projections on the ends of the fork engage when required
substantially as described and illustrated herein.
