1. A device of the class described comprising an
upright inner ring and an outer ring concentric
with and spaced apart therefrom, an internal
gear rigid with said outer ring intermediate the
mudguard 53 thereto, and additional bolts, not
width of the latter, a tire mounted on said outer .
shown, may be provided for this purpose. A pair
of additional frame members 55 are mounted be
tween the ears 3!! and the engine frame, between
ring, a gear housing mounted on said inner ring
and having a gear in mesh with said internal gear,
which a cradle 56islpivotally mounted.
Adjacent each ear v3|’, a yoke bar-51 is pivot
ally mounted on the bolt 31, in the converging
extremities of which a small auxiliary wheel 58
is rotatably mounted.
Springs 59, secured to the
inner extremities of the bars 51 and to the inner
ring l0, normally urge the wheel 58 upward from
the ground. A cable 60 is securedat one end to
one yoke member 51 and at the other end to the
cradle 56, by means of which the wheel 58. may
be brought downward toward the ground upon
rotation of the cradlef56, ‘the intermediate length;
and path of the cable 60 being not shown.‘ A‘
wheel 6|, constructed'_‘and mounted ‘similarly. to
the wheel 58,iis" provided in the same position
at the rear of the device. 'A‘cable 62 is similarly
connected to the cradle '56'through a path not
shown, so that it may be similarly'operated.
Between the tire 23 and the wheel 58,- a brakingv
device is provided‘on' the'yokes'51' of each wheel
58 and 6|. This device consists of a cylindrical
shoe 63 rotatably mounted intermediate the
length of a rod 64 which’ has one end pivoted in
an ear 65 rigid with one yoke ‘member 51. The
rod 64 is widened at '65,'and a hole extends'there
through for the passage therethrough of the
ballbearings mounted between said rings on each
side of said internal geaiggretainer rings rotat
ably supporting said ballbearings, means. for ro
tating said second-named gear, and annular rims
loosely locking said inner and outer rings to
gether.
2. A ‘device of the class described comprising
an upright inner ring and an outer ring concen

gear rigid with said outer ring intermediate the
width of the latter, a tire mounted on said outer
ring, a gear housing mounted on said inner ring 20
and having a gear in meshlwith said internal
gear, ballbearings mounted ‘between said- rings on
each side of said internal gear, ‘retainer, rings
rotatably supporting said ballbearings, means for
rotating said second-‘named gear, a, chair resil

and havinga gear: in mesh with said internal
gear, ballbearings mounted between said rings
of the rod 64, has a cable ‘61 attached thereto,
the other vend of which is secured in‘ the usual
rotatably supporting said ballbearingslmeans for
manner to'one of "the handle bars‘ 5|, or‘toany
40 other convenient place where it ‘may be readily
operated by the driver. Tautening of the cable
61 will urge the shoe 63 against’ the tire 23 to
brake the device. "The detailed constructionpf
the brake, as described, is one example only, al
