Improvements in Driving-gear for Cycles or other Vehicles.
I, WILLIAM RAINES, of 95 East Saville Street, South Shields, Master
Mariner, 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 driving-gear for cycles or other vehicles,
and has for its object to allow of a high rate of speed being imparted to a vehicle
by means of the said driving-gear, without at the same time such driving-gear
calling for a greater amount of power, than was, and is at present, required to
propel vehicles fitted with the old-fashioned driving-mechanism.
And in order that this my invention may be more fully understood, and readily carried
into effect, I will proceed to describe same with reference to the accompanying sheet
of illustrative drawings, wherein :
Fig. 1 is a side elevational view of a bicycle of the safety type, with my
gear applied thereto,
driving-
Fig. 2 being a view, partly in section, of the driving-gear, with a portion of same
removed for convenience in shewing the invention, while
Fig. 3 is a section, of the driving-gear, (certain portions thereof being shewn in
elevation), upon line x, x, of Fig. 2.
Referring to the drawings in which like letters of reference indicate corre-
sponding parts throughout the several figures the part marked a represents a disc
or wheel which is keyed to or fixedly mounted at 62 upon the axle & carrying the
cranks bl.
This said disc or wheel a is flanged as at a¹, the inner periphery of which
flange a' is provided with teeth a² adapted to engage with the teeth of the wheel c,
keyed to one end of a spindle c', which latter passes through and works in, suitable
bearings in a side projecting portion d' of a case d.
This case d which is of circular form, encloses the disc or wheel a, and the
toothed-wheel c, the crank-axles b also passing through such case, and working in
bearings d in the sides of same.
To the other extremity of the spindle c' carrying the toothed-wheel c, is keyed a
chain-wheel e over which passes the driving chain connecting same with the cog-
wheel gl mounted upon the hub of the wheel g generally known as the driving-
wheel.
The frame h of the cycle may be of any suitable construction, but I preferably
carry same downward so that the case d may be fixed within the semi-circular
curve formed by such frame h, though the said case may be fixed to any other suitable
portion of such frame. The crank-axle b can also work in suitable bearings in the
part ¹ or any other suitable portion of the frame h, in addition to the bearings in
the case d, or it may, if found desirable, be entirely supported by the said case d.
Having now particularly described and ascertained the nature of my said inven
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improvements in driving-gear for cycles or other vehicles, substantially
as described and illustrated.
2. In driving-gear for cycles or other vehicles, the employment of a flanged
wheel fixedly mounted upon the crank-axle and having teeth upon the inner

page_text: periphery of such flange to engage with a toothed-wheel keyed to a spindle
mounted in bearings in a side extending portion of a case partly enclosing the
mechanism and in bearings in which the crank-axle works to which spindle a
chain-wheel is keyed over which passes the driving chain connecting same with the
cog-wheel upon the hub of the driving-wheel, substantially as hereinbefore specified 5
and as illustrated by the accompanying drawings.
Dated this 7th day of December 1894.
