PROVISIONAL SPECIFICATION left by the said Herbert John Haddan nat
the Office of the Commissioners of Patents on the 14th June 1881.
HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Solicitors of
Patents, of 67, Strand, in the City of Westminster, Civil Engineers. "IMPROVE-
MENTS IN TRICYCLES.' A communication from abroad by Charles Wood Oldreive,
of Massachusetts, of the United States of America.
"
The first part of the Invention consists in the combination of a main or driving
wheel provided with a rim, two hubs, and two sets of spokes, with a car or carriage
body, and tubular journals thereto arranged within such wheel, and with a perch,
auxiliary wheels, and an axle, the said wheel and car being provided with moans
or mechanism to enable a person while in the car to revolve the wheel in order to
put the tricycle in movement.
The second part of the Invention consists in the combination of certain tubes
and arms extending therefrom, with the wheel and the car made, arranged, and
combined as stated.
The third part of the Invention consists in the combination of a steering yoke
and lines with the main wheel, the auxiliary wheels, and axle, the car and the
perch, the said lines being led into the said main wheel through tubes within the
tubular journals projecting from the car.
The fourth part of the Invention consists in a tricycle consisting of a main
wheel provided with a rim, two separate hubs, and two sets of spokes, a car
arranged within such wheel, and provided with tubular journals to enter the hubs
of the wheel, a furcated perch, an axle, and two wheels thereto, a steering yoke
and lines, brake tubes and their arms, and mechanism for revolving the main wheel
by a person while within the car, the outer arins of the brake tubes serving as
brakes to arrest the motion of the wheel.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, and
of an Order of the Lord Chancellor, filed by the said Herbert John Haddan
in the Great Seal Patent Office on the 17th December 1881.
HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Solicitors of
Patents, of 67, Strand, in the City of Westminster, Civil Engineer.
"IMPROVE-
MENTS IN TRICYCLES." A communication from abroad by Charles Wood Oldreive,
of Massachusetts, of the United States of America.
The Invention is represented in the accompanying Drawings, of which Figure 1
is a top view, Figure 2 a side elevation, Figure 3 a longitudinal section, and
Figure 4 a transverse section of a tricycle containing this Invention, the nature of
which is defined in the claim or claims hereinafter presented.
In the said tricycle a platform-car or a carrier-body A. in the form of a boat is
wholly within the driving wheel B, which has to its rim a two separate sets of
spokes b, and two separate hubs c, c, all arranged as shown.
Tubular journals i, d, project from opposite sides of the body A through the
hubs of the wheel, and fixed to the said journals are the prongs e, e, of a furcated
perch C, such perch being pivoted to an axle D provided with two bearing
wheels E, E. The pivot g of the perch and axle has fixed on its upper part a cross-
bar or yoke F, to whose outer ends or parts steering lines h, h', are fastened, and
thence are led to and through two tubes i, i, arranged concentrically within the
tubular journals d, d, and thence into the car or body A.
Each of the tubes i has an arm k fastened to and extended up from it at its
inner end, and furthermore such tube also has another but longer arm projecting
down from it to the ground. Each tubo i, with its two arms k, l, constitutes a
brake for arresting the movements of the tricycle as occasion may require, all of
which while the vehicle may be in motion can be effected by the rider by grasping
the two arms k, and moving them so as to force the arms l, l, into close contact
with the ground.
Each hub of the wheel bas fixed to it on its inner side and concentric with such
hub a gear m, which engages with a driving gear o by means of an intermediate
gear n, such gears being shown in dotted lines in Fig. 2. The said intermediato
and driving gears are applied to the car so as to be capable of being revolved by a
crank s fixed on the arbor of the driving-gear.
A person, while either sitting or standing within the car, can readily put the
vehicle in motion, either backward or forward, by taking hold of and simul-
taneously revolving the two cranks, and he can change the direction of the motion
by pulling on either of the steering lines, so as to cause the axle of the supplementary
wheels to assume an oblique position to the plane of the wheel B.
From the above it will be seen that, owing to the large diameter which may be
given to the wheel B, the vehicle can be run at a very high degree of speed, and
be easily manipulated by a person when within the car.
I do not confine this Invention to the precise shape or construction of the car as
shown, for such may be materially varied without changing the character of the
improvement.
CLAIMS.
1. The combination of the main or driving wheel B provided with the rim, two
hubs, and two sets of spokes, as set forth, with the car or carriage body A, and its
tubular journals arranged within such wheel, and with the perch C, auxillary
wheels E, E, and their axle D, all being adapted substantially as set forth, the

page_text: person while in the car to revolve the wheel in order to put the tricycle in
movement.
2. The combination of the tubes i and their arms k, l, with the wheel B and
car A, all being constructed and applied substantially as set forth.
3. The combination of the steering-yoke F and lines h, h, with the main wheel B,
the auxiliary wheels E, E, and axle D, the car A, and perch C, arranged and adapted
substantially as set forth, the said lines being led into the said main wheel through
tubes i within the tubular journals d, d, projecting from the car, and all being
essentially as specified.
4. The tricycle, substantially as described, consisting of the car A, main wheel B,
furcated perch C, auxiliary wheels E, E, their axle D, steering yoke F, lines h, h,
brake-tubes i, i, and their arms k, k, l, l, and the mechanism for revolving the main
wheel, all being constructed, arranged, and adapted essentially in manner as repre-
sented, and to operate as described.
In witness whereof, I, the said Herbert John Haddan, have hereunto set my
hand and seal, this Tenth day of December, A.D. 1881.
