PROVISIONAL SPECIFICATION.
Improvements in Wheel Gearing for Transmitting Power.
WILLIAM KNEEN 7 Norfolk Street Manchester Mechanical Engineer do
hereby declare the nature of this invention to be as follows:-
My invention relates to improved apparatus or means for transmitting motive
power and consists of a peculiar construction and arrangement of wheels whereby
gain of power is obtained without a corresponding loss of speed.
According to my invention I fix at suitable distances apart on a shaft, several
wheels constructed as described in the Specification accompanying my application
for Letters Patent dated 28th May 1895 No. 10517, except that the teeth operated'
upon by those on the discs or wheels on the driving shaft are preferably attached
at points on the outer rings differing from those described in my specification
aforesaid, each wheel consisting of a boss to which is pivotted an outer ring the
pivots on which these rings oscillate being respectively arranged diametrically at
right angles to each other. The outer rings of these wheels are provided with
teeth or projections, each ring preferably having two teeth or projections arranged
diametrically opposite each other. These wheels are fixed on the shaft so that the
teeth or projections on one wheel are in advance circumferentially of the teeth or
projections on the adjacent wheel so that the teeth on the whole of the wheels form.
a helix round the shaft on which the said wheels are fixed. Fixed at an angle to
the shaft which carries these wheels are suitable supports against which the outer
rings of the several wheels bear, ball bearings being preferably interposed between
the said rings and the inclined supports to prevent friction. On a shaft arranged
to rotate parallel to the shaft carrying these sectional wheels, are keyed a.
corresponding number of discs or wheels of the same diameter as the outer rings.
of the sectional wheels and each having say two teeth or projections diametrically
opposite each other, the teeth or projections on one disc or wheel being in advance
of the teeth or projections on the adjacent disc or wheel. These discs or wheels
are situated on the shaft so that the teeth on each will gear with the teeth or
projections on the rings of a corresponding sectional wheel on the other shaft.
These discs or wheels rotate in a plane at right angles to the axis of the shaft on
which they are carried whilst the outer rings of the sectional wheels rotate at an
angle other than a right angle to the shaft, the said angle being determined by the
inclination of the supports on which they bear. The several parts of wheels come
into gear in succession and when teeth on the rings are in the positions nearest to
the shaft. By this arrangement whilst the speeds of rotation of the two shafts
may be equal, power transmitted from the shaft carrying the disc or wheels to the
shaft carrying the sectional wheels is increased.

I WILLIAM KNEEN of 7 Norfolk Street Manchester in the County of Lancashire,.
Mechanical Engineer 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 has for its object to construct wheels in such a manner that
their power to rotate the shafts or the like on which they are carried may be
increased.
According to my invention I construct wheels of sections, or rings, each wheel
preferably consisting of two rings arranged one within the other; the outer one
being connected to the adjacent ring by pivots or trunnions, and the inner section,
or ring, being pivotted to a boss, or collar, fast on the shaft and of a size to enter
the said inner section or ring. The pivots or trunnions on which the inner ring
turns are arranged diametrically at right angles to the pivots or trunnions on which
the outer ring turns. The outer rings of these wheels are provided with teeth or
projections; each ring preferably having two teeth or projections arranged
diametrically opposite each other. A series of these wheels are fixed on the shaft
so that the teeth or projections on one wheel are in advance circumferentially of
the teeth or projections on the adjacent wheel, so that the teeth on the whole of
the wheels form a helix round the shaft on which the said wheels are fixed. Fixed
at angles to the shaft which carries these wheels are suitable supports, preferably
two girders on each side of the shaft, and to the said girders transverse bearers are
attached. Anti-friction rollers on which the rings bear are attached to the said
transverse bearers to prevent friction. On a shaft arranged to rotate parallel to
the shaft carrying these sectional wheels are keyed a corresponding number of
wheels of the same diameter as the outer rings of the sectional wheels, and each
having preferably two teeth or projections diametrically opposite each other the
teeth or projections on one wheel being in advance of the teeth or projections on
the adjacent wheel. These wheels are situated on the shaft so that the teeth ou
each will gear with the teeth or projections on the rings of a corresponding sectional
wheel, on the other shaft.
And in order that my said invention may be fully understood I shall now proceed
more particularly to describe the same; and for that purpose shall refer to the
several figures on the annexed sheet of drawings. The same letters of reference
indicating corresponding parts in all the figures.
Figure 1. of the accompanying drawings is a face view of wheels constructed
according to my invention.
Figure 2. is a face view shewing a succession of wheels.
Figure 3. is a plan shewing the outer ring in a position other than a right angle
to the shaft.
Figure 4. shews in plan both the inner and outer rings at an angle other than a
right angle to the shaft.
Figure 5. shews the girders with transverse bearers and anti-friction rollers for
supporting the rings.
A. is the shaft on which the improved wheels are carried. The improved wheels
consist of a boss or collar B. surrounded by a ring C connected to the said boss or
collar by pivots or trunnions c on which the ring can oscillate. Surrounding the
ring C and connected thereto by pivots or trunnions d the ring D can oscillate.
The pivots or trunnions c are arranged diametrically at right angles to the pivots
or trunnious d so that the rings so combined constitute substantially a universal
joint or coupling. E is a wheel preferably having two teeth or projections

page_text: attached to an ordinary shaft F. 9 shews how the wheels are fixed on the shaft
so that the teeth or projections on one wheel are in advance circumferentially of
the teeth or projections on the adjacent wheel. H is the transverse bearer or
support for the rings. I is the anti-friction rollers. J is the girder attached to.
the transverse bearers.
Having now particularly described and ascertained the nature of this inven--
tion and in what manner the same is to be performed I declare that what I
claim is :-
Wheels composed of sectional rings arranged one within the other and connected
together by pivots or trunnions the innermost ring being pivotted to a boss or
collar fixed to the shaft the angle of the rings with reference to the axis of the
shaft being capable of varying or of being varied substantially as and for the.
purpose herein before described.
