I, JAMES HOWIE of 50 Ropework Lane, in the County of the City of Glasgow,
North Britain, Machinist, do hereby declare the nature of this Invention to be as
follows:-
This Invention relates to improvements in and connected with oycles and other
vehicles and has for its object the substituting for the chain and chain wheels an
arrangement of spur gearing whereby increased speed is obtained.
In carrying out my Invention, I mount upon the treadle axle a spur wheel of
any desired diameter, (say for example nine inches) and this wheel which turus
with the motion of the pedals gears with an intermediate or idle spur wheel carried
on suitable bearings in the framing of the machine. The intermediate spur wheel
gears into a pinion mounted on the axle of the rear wheel of the cycle or other
vehicle. The bearings are made adjustable.
When it is desired to impart a varying speed by altering the gearing of the
machine, an additional intermediate spur wheel or wheels of increased diameter
is employed with an arrangement by which the said wheel or wheels is or are
thrown in and out of gear with the driving wheel and pinion.

Improvements in and connected with Cycles and other Vehicles.
I, JAMES HOWIE, of 50, Iopework Lane, in the County of the City of Glasgow,
Scotland, Mechanic, 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:-
My Invention relates to improvements in and connected with cycles and other
vehicles and has for its cbject the substituting for the chain and chain wheels an
arrangement of spur gearing and a method for carrying the same.
In order that my Invention may be properly understood and readily carried
into effect I have hereunto appended a sheet of Drawings of which
Figure 1 is a side elevation of a cycle constructed according to my Invention.
Figure 2 is a part plan of the same and
Figure 3 is an end view of bracket.

page_text: Figure 4 is a plan of the bracket.
Figure 5 is part plan showing an arrangement of four wheels of different
diameters.
Figure 6is also a part plan shewing an arrangement of five gear wheels also of
different dimensions.
Figure 7 is view of different construction of wheel.
In carrying out, my Invention I mount upon the treadle axle A a spur wheel B
of any desired diameter (say for example 10 inches) and this spur wheel B which
turns with the motion of the treadle C gears with an intermediate or idle spur
wheel D carried on a bracket, the construction of which I shall hereafter describe.
The intermediate spur wheel D gears into a pinion E mounted on the axle K¹
of the rear wheel F of the cycle or other vehicle.
The bracket G,-which is of box-like construction, one end g of which is
connected to the treadle axle A, while the other is connected to the rear wheel
axle K', is made with a step H on each end thereof in order not to have the treadles
projecting out from the frame of the machine beyond the ordinary requirements.
These stepped ends are made of stirrup-shape so that the wheels work freely
therein as shown more particularly in Figures 1, 2, and 5. A recess I is also
provided in the bracket G into which an adjustable box-bracket K is fitted and
this acts as or forms a bearing for tho axle J of the intermediate wheel D, so as
to keep the gearing in alignment.
In place of the arrangement of gearing as described and shewn in Figures 1
and 2, I might arrange it so as to have four gear wheels A, D', D³, and E as
shewn in Figure 5, and in this case the bracket G is made a little wider to allow
of the free movement of the gear wheel. Or I might have five gear
wheels A, D, D', D, and E in one line and of different diameters as shown in
Figure 6.
In this case the bracket G is shewn single although it may be a double
one and is constructed with a separate recess I and box-bracket K for each axle
of the gear wheels.
Having now particularly described and ascertained the nature of my said In-
vention and in what manner the same is to be performed, I declare that what I
claim is:-
In cycles and other vehicles, in combination with the arrangement of gearing,
the bracket and bearings for carrying the same constructed substantially as
described and illustrated in the several figures of the accompanying sheet of
Drawinga.
