page_text: We, ROBERT HUGH FORSYTHE FINLAY of Victoria Square in the City of Belfast and
County of Antrim in Ireland Soap and Candle Manufacturer and ARCHIBALD HENRY
FINLAY of same place Engineer, do hereby declare the unture of this invention to be
as follows:-
Our invention relates to the transference of power from one rotating shaft to
another which it is desired to drive at a different speed in the same or the opposite
direction..
In order to obtain a slow speed from a shaft running at a high velocity we fix upon
it a small wheel having a roller or rollers in contact with and actuated by it. Each
roller is formed in two sections of different diameters, the axis of both being in the
same straight line.
We employ two large rings concentric with the wheel and revolving about it, each
of which inakes contact internally with one section of the roller, or with a correspond-
ing section of each of the rollers, if more than one is used. We fix one of these rings
to prevent its movement, and when the shaft is caused to rotate the other ring, being
left free, will revolve slowly in one direction. If the latter ring be fixed and the first
left free it will revolve slowly in the opposite direction.
In the arrangement just set forth the wheel is in contact with that side of the
rollers which is next to the shaft and the rings are on their further side. But that
order may be reversed and the wheel be arranged so as to be in gear with the rollers
on the side further from the shaft while the rings are in gear with the nearer side to it.
We may also obtain different rates of slow speed from the same shaft at the same
time or equally slow rates in opposite directions by adding a section or sections to the
roller or rollers and gearing with each additional section a ring similar to those already
mentioned. The slow motion thus fattained may be transmitted to any shaft or
machine it is desired to drive slowly by well known means.
Conversely, it will be evident that by actuating the free ring at a low speed we can
secure a high speed in the rotation of the wheel and shaft.
The wheel, rollers and rings may be furnished with teeth which will prevent the
rollers from altering their relative positions in our device while at work, or we may
achieve the same end, where we rely upon friction for transmission of the power, by
placing buffer-rollers between the operating rollers, or by fixing each roller to a rigid
ring or frame.
And the rings may be placed upon or form portions of wheels.

page_text: We, ROBERT HUGH FORSYTHE FINLAY of Victoria Square in the City of Belfast and
County of Antrim in Ireland Soap and Candle Manufacturer and ARCHIBALD HENRY
FINLAY of same place 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 :-
Our Invention relates to the transference of power from one rotating shaft to
another which it is desired to drive at a different speed in the same or the opposite
direction.
In order to obtain a slow speed from a shaft running at a high velocity we fix upon
it a small wheel having a roller or rollers in contact with and actuated by it or we may
employ several wheels of the same size for the purpose of giving stability to the roller
or rollers and better transmitting the power. Each roller is formed in two sections of
different diameters, their axis being in the same straight line. The roller may be
constructed of one piece in sections as described or each section may be a separate
piece, such sections being fixed rigidly togetlier upon an axle. The same size of
section may be employed more than once in a roller.
We employ two large rings concentric with the small wheel or wheels each of which
rings makes contact internally with one section of the roller or with a corresponding
section of each of the rollers if more than one is used.
We fix one of the rings to prevent its movement and when the shaft is caused
to rotate the other ring being left free will revolve slowly in one direction about
the axis of the high speed shaft. If the latter ring be fixed and the first left
free it will revolve slowly in the opposite direction. And the rings may be fixed
upon discs or form portions of wheels rotating with or upon shafts co-axial with
the high speed shaft to support them in position.
In the arrangement just set forth the small wheel or wheels will be in contact
with that side of roller which is next to the shaft and the rings are on their
further side. But this order may be reversed and the wheel or wheels may be
enlarged to carry an overhanging rim or overhanging rims so as to be in gear
with the roller or rollers on the side further from the shaft, while the rings are
decreased and gear with the side nearer to it. In this arrangement each ring
preferably forms the periphery of a wheel fixed on shaft.
We also obtain different rates of slow speed in the same or opposite directions
from the same shaft at the same time by adding a section or sections to the
roller or rollers and gearing with each additional section a ring similar to those
already mentioned. The slow motion thus attained may be transmitted to any
shaft, pulley or machine it is desired to drive slowly by well known means.
Conversely it will be evident that by actuating the free ring at a low speed we can
secure a high speed or different rates of high speed in the wheel or wheels and shaft
or shafts.
We may prevent the axles of the rollers from altering their relative positions in
our device while at work by placing buffer rollers between the operating rollers or by
fixing each roller by an axle to a rigid ring or frame. Or we may achieve the same
end and increase the potentiality of the machine by substituting a toothed wheel for
each section of the rollers and likewise furnishing the small wheels and the rings
with teeth in which arrangement the fixing of the axles to the rigid ring or frame
serves also to keep them at a proper distance from the high speed shaft. But the
same result may be also attained by the use of smooth wheels, roller sections and
rings in connection with the toothed gearing.

page_text: The mechanisms we have described may be enclosed in cases filled or partly filled
with a suitable lubricant when toothed gearing is employed or used as a protection
to the moving parts or to keep out moisture, oil or other deleterious matter when
friction alone is relied upon to transmit the power..
And in order that our said Invention may be more fully understood we shall now
proceed to refer to the drawings hereunto annexed the same letters of reference
indicating the same or corresponding parts throughout all the figures.
Fig. I is a longitudinal section of the Machine shewing a high speed shaft
carrying two small wheels and rollers in sections of different diameter rotating with
their axles about the shafts and wheels and some of the sections gearing with the
Binall wheels; rings in contact with the sections of the rollers on their outer sides; a
slow speed shaft; a disc or wheel connecting a free ring with the slow speed shaft;
a case, of which the fixed ring forms a part, enclosing the mechanism, and bearings
and stuffing boxes at the ends.
Fig. II. is an end view of the fixed ring and those sections of the rollers with
which it is in contact as shewn in Fig. 1.
Fig. III. is an end view of the revolving ring and those sections of the rollers with
which it is in contact; also one of the wheels on the high speed shaft as shewn in
Fig. 1.
Fig. IV. is a view of the Case at the high speed shaft and as shewn in Fig. 1, and
Fig. V. is a longitudinal section of a Machine having three rings each connected'
with a separate pulley and shewing rollers revolving on axles connected with a disc
or wheel having its bearing on the high speed shaft; also the high speed shaft
carrying two small wheels.
a is the high speed shaft carrying the small wheels, b, b; c, d, d, e, el are sections
of the rollers; f, f, are the axles upon which the rollers rotate or revolve and g is a
dise or wheel to which the axles, f, f, are rigidly attached; h, h', h, are the rings
in contact with the sections of the rollers.on their outer sides; i, 2, 1, are pulleys
rigidly connected with the rings, h, h', h"; kis the slow speed shaft; is the disc or
wheel connecting the free ring, h, with the slow speed shaft, k; m is the Case with
the bed plate n, the bearings, o, o¹, and the stuffing boxes, p, pl at the ends.
The high speed shaft may be rotated in either direction but assuming it to be
driven clockwise (by which we mean as the hands of a clock) one of the rings being
fixed, the axes of the rollers or toothed wheels will revolve about it clockwise also
while such rollers or toothed wheels will revolve on their own axes in the
opposite direction. If the free ring is in contact with sections of the rollers of
sinaller diameter than those which are in contact with the fixed ring it will
travel clockwise but if in contact with sections of larger diameter it will travel
in the opposite direction.
In the Machine shown in Fig. V of the drawings, if the middle ring (h¹) be
fixed, the ring (h) in contact with a smaller section of the rollers will travel
clockwise also, but the ring (h), in contact with a larger section will travel in
the opposite direction at the same time. Again the middle section of the rollers
will travel clockwise or the reverse according as the largest ring (A) or the smallest
ring (h) is fixed.
As the rings (h, h, h¹¹) are rigidly connected with the
pulleys (i,,) respectively the motion of the middle pulley (1) can therefore be
reversed at will while the high speed shaft runs continuously in the one direction by
applying a brake, so as to fix it; (¹) and then loosing it and similarly fixing the
pulley (1) instead.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same may be performed we would have it
to be understood that we do not claim as of our invention or the exclusive use
of small wheels, rollers or toothed wheels and fixed or free rings except where the
same are constructed and employed in the manner and for the purposes hereinbefore
described, nor do we claim the use of shafts, axles, discs, pulleys, bearings or

page_text: stuffing boxes or of any of the separate mechanical parts of our apparatus but we
declare that we claim
1. The use of a roller or rollers in sections or pieces or of toothed wheels of
different diameters but on the same axial line in contact with and actuated at the
peripheries thereof by a wheel or wheels and arranged with rings of relatively
different diameters constructed and employed substantially in the manner and for
the purposes herein before described and shewn in the drawings hereunto annexed.
2. The use of a roller or rollers in sections or pieces or of toothed wheels of
