IMPROVEMENT IN TRICYCLES AND BICYCLES
Year: 1885

page_text: I, HENRY PIPE, of 50 Edgware Road, Hyde Park, Domestic Agent, do hereby
declare the nature of my invention for IMPROVEMENT IN TRICYCLES AND BICYCLES
to be as follows:-
It is usual at the present time to so construct tricycles and bicycles that they
are propelled by means of treadles mounted upon cranks, which is a rotary motion.
According to my invention I provide upon the axis of the main wheel, a chain
wheel, and an endless chain passes around this wheel, and also around another
larger chain wheel. The axis of the larger wheel has a pair of crank arms upon
it, one on either side, and connecting rods couple these arms with sockets, working
up and down in a slot in the hollow fork. When by means of the feet the sockets
are alternately depressed, they impart movement through the rods already described
and thus the tricycle or bicycle is propelled.
I sometimes work it with a slot in a solid fork, or in a grove on the fork.

page_text: Fig. 1-Shows a side and front view of the invention applied to a bicycle; by
which motion is given to the driving wheel, by means of chain and chain wheels
from the piston pedals, working in tubular extensions of the driving wheel fork.
Fig. 2 Shows a side and front view of the invention, for attaching and driving
a tricycle.
Fig. 3-Shows a side view of a bicycle to which is applied the invention, with
the piston pedals working in a flat slotted fork, transmitting the motion to the
driving wheel by means of chain gearing.
Fig. 4 Shows a side view of a bicycle with a flat slotted fork by which the
power is transmitted from the piston pedals direct to the driving wheel cranks.
Fig. 5 Shows the application of the invention to a tricycle.
Fig. 1-Shows a front & side view of a bicycle, by which motion is given by two
piston pedals 1, working in two tubular extensions 2, of the driving wheel fork 3,
driving the cranks 4, by means of the connecting rods 5, through the chain wheels 6,
direct to the driving wheel axis 7, revolving in the bearings 8, carried on the
brackets 9.
Fig. 2 Shows the application of the invention for driving tricycles Is con-
structed of a light rectangular frame 1, having slotted sides 2, in which the piston
pedals 3 work; driving the two throw crank and chain or spur wheel 4, by means
of connecting rods 5, revolving in the bearings 6. Motion being transmitted by
the chain or spur gearing 7 to the axle 8, of the tricycle to which it is applied.
9 and 91 are attachments to the framing of the machine, which can be of any form
to suit the class of machine to which it is to be applied. I sometimes prefer to
work the cranks and gear outside the frame instead of inside the frame as shown.
Fig. 3 Shews a side view of a bicycle with the piston pedals 1 working in a flat
slotted fork 2 transmitting the motion to the driving wheel 3 by means of the
connecting rods 4, cranks 5, and the chain wheels 6 and 6¹.
Fig. 4 Shows a side view of a bicycle having a slotted extended driving wheel
fork 1, in which the piston pedals 2 work, transmitting the motion direct to the

page_text: driving wheel 3, without the chain gear by means of the connecting rods 4, and
cranks 5.
Fig. 5 Shows a side view of a tricycle with the driving gear fig. 2.-1 is the
driving wheels, 2 the steering wheel, 3 the piston pedals, 4 the connecting rods,
5 the crankshaft, 6 the chain or spur wheel gearing with the axle wheel 7, which
transmits the power from the piston pedals and crankshaft to the axle of the driving
wheels 1.
I wish it to be understood that either chain or spur gearing can be used, when
chain gearing is used the crankshaft and wheel travels in the same direction
as the axle. When spur gear is used in lieu of chain gearing the crankshaft
revolves in an opposite direction to the axle. With three spur wheels in a opposite
direction.
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 s
Firstly. In bicycles and tricycles a combination of piston pedals working
vertically up an down as shown in Fig. 1 and 4; in tubular or flat slotted
frames, driving the main axle cranks direct; by means of connecting rods.
Secondly. In bicycles & tricycles a combination of piston pedals working up and
down in tubular slotted frames as shown in Figs. 1, 2, 3, and 5; driving an
intermediate crankshaft or crankshafts transmitting the power to the main axle
by means of chain or spur gearing as described and shown in the foregoing
specification.
