IMPROVEMENTS IN TRICYCLES AND OTHER VELOCIPEDES
Year: 1884

page_text: COMPLETE SPECIFICATION,
I, JOSIAH JACKSON of 59 Lower Ford Street, in the City of Coventry, in the
County of Warwick, Machinist do hereby declare the nature of my invention for
IMPROVEMENTS IN TRICYCLES AND OTHER VELOCIPEDES and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :—
.
First. Driving gear, shown on Drawings, figured, 1, 2, 3, 4, 5, 6, 7 and 8.
Second. Steering gear, shown on Drawings, figured 9, 10, 11 and 12.
Third. Break gear, shown on Drawings figured 13 and 14.
Fourth. Back bone, shown on Drawing figured 15.
Fifth. Couplings, shown on Drawings figured 16, 17, 18, 19, 20, 21, 22, 23
and 24.
Sixth. Adjustible Handle shown on Drawings, figured 25, 26, 27 and 28.
Drawings figured 29, 30 and 31 respectively show various parts applied,
and tend more clearly to explain the improvements in tricycles and other
velocipedes.
The nature of my said invention, and the manners in which the said invention
are to be applied, I declare as follows.
1. Driving gear, the novelty is in the regular propulsion of the wheels
backward, forward or alternately at the will of the rider, by means of a mitre
wheel A, keyed or fitted to the axel or otherwise to the bush B, extending through
the chain wheel and break drum C, the latter having two or more pinion wheels D,
attached or running on pins or spindles E, within the drum and wheel F, by
means of a chain G, causing the drum to rotate, with the pinion wheels D in the
same working between the mitre wheel A and plate wheel H. The plate wheel H
being attached to the hub of loose wheel revolving upon axel or bush B, thus
causing the forward, backward or alternate action at will. This part of my invention
applies to central driving purposes, as shown in Figure 8, by a piece of tube or
hollow axel I, being fitted to the mitre or plate wheel, and extending thence to
the loose wheel upon the axel.
'
2nd. The steering gear is new, and its object is such that the steering wheel will
remain at any given position at the will of the rider. Thus on turning the steering.
Handle A¹, the endless screw A³, revolves giving rotation to the worm wheel A³,
fixed on centre pin A. Causing the lever attached A³ to rotate, thus causing the
action by a swivel joint A, and rod A7, to a steering arm A8 attached by a second
swivel joint A to the fork top of steering wheel A¹º.

page_text: 3rd. The break gear is new and its action is as follows.
By turning the
handle B¹, the teeth of an endless screw B³, running in a worm wheel B³, moves
an eccentric action B, from which a rod B³, attached thereto by means of pins and
nuts moves a lever B, working on the centre or stud, to the other end of which
is attached the break band or steel spring B', which clips the drum. The use and
application of this gear is to hold the band firmly on the drum at any pressure,
but such pressure is not however necessary to be continuously applied after it is
once set, the break then being held firmly into its place until released.
4. The Back bone C is new and of an oval or eliptie form. Its object being
to give more rigidity or firmness to the machine. It is hollowed in section and
tapered from one end to the other.
5th. The couplings are new and are so `arranged that a machine built for one
person can be easily extended and made wide enough for two, by the application of
a cotter key to a coupling, consisting of two rings threaded on to the slotted ends
of the tubes or the axel as required, and forming a perfectly firm joint by the
united application. There being three or more couplings to each machine with
one cotter key only to each coupling. This cotter key is wedged shaped at both
ends to fit the coupling or rings (two in number), one of which has two inclines,
one on each side, made to fit the key, the other is made loose without inclines.
The drawings show the application and thus the tube D' being slotted to admit of
cotter key D being firmly fixed into the plug D³. The cotter key D (having
inclines at both ends) is passed through the coupling or rings D and D³, and the
coupling or ring D' (having two inclines, one on each side for key to fit) is twisted
at the back of D* into the cavity of the key D, pulling the wedged shaped ends
of the key to home or stop D7, and thereby making the machine rigid and solid
without screws.
The end of each tube at the joints is brazed. Except the joint
of the axel, one end of which is solid and the other brazed. The key passes
through the slotted ends of tubes or axel in all cases & is brazed to tube, as is
also ring D. The coupling ring D³ is in two parts & secured by a screw at
each end.
Thus
6. Adjustible handle. The utility of which is to raise or lower the handle in
such a manner as to suit the height of the rider, and its application is new.
by means of an adjustible rod E, with T piece E', at the head for the reception of
the handle bar E³, the adjustible rod E' moves up and down in the tube E', and
has a slot or key way E³ to keep it in position, and is secured, when raised or
lowered, by means of a set screw E affixed in the ring or band E' round the top
of tube, and at back by set screw key E³.
Having now, particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is 1 Driving gear. 2. Steering gear. 3. Break gear. 4. Back bone.
5. Couplings. 6. Adjustible handle.
