Year: 1855

page_text: LETTERS PATENT to Joseph Edlyn Outridge, of Constantinople, in the
employ of the Ottoman Government, but now residing at No. 134, Black-
friars Road, in the County of Middlesex, for the Invention of "Im-
PROVEMENTS IN TRANSMITTING MOTIV Down"
PROVISIONAL SPECIFICATION left by the said Joseph Edlyn Outridge
at the Office of the Commissioners of Patents, with his Petition, on the
13th January 1855.
I, JOSEPH EDLYN OUTRIDGE, of Constantinople, in the employ of the Ottoman
Government, but now residing at No. 134, Blackfriars Road, in the County
of Middlesex, do hereby declare the nature of the said Invention for " Iм-
PROVEMENTS IN TRANSMITTING MOTIVE POWER" to be as follows:-
This Invention relates to a peculiar construction and arrangement of
mechanism for transmitting a rotatory or semi-rotary motion when required,
whereby the use of toothed gearing is dispensed with, and consists in the
employment of two discs, keyed near to each other on to a main driving shaft,
and fitted near their peripheries with a number of rollers, working on their axes
in plummer blocks inserted on the faces of the two discs, the axes of the rollers
being in the direction of the radii of the discs.
Between these discs is fitted to revolve a second shaft, which is twisted, or

page_text: has a spiral blade or continuous incline formed' upon it, and it is upon this
continuing revolving incline or spiral blade that the rollers inserted in the discs
operate during the revolution of the main driving shaft, thereby communicating
rotatory or semi-rotatory motion to the second' shaft.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph. Edlyn Outridge in the Great Seal Patent Office on
the 13th July 1855.
TO ALL TO WHOM THESE. PRESENTS SHALL COME, I, JOSEPH
EDLYN OUTRIDGE, of Constantinople' in the employ of the Ottoman Govern-
ment, but now residing at No. 134, Blackfriars Road, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of January, in the year of our
Lord One thousand eight hundred and fifty-five, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Joseph Edlyn Outridge, Her special license that I; the said Joseph Edlyn
Outridge, my executors, administrators, and assigns, or such others as I, the
said Joseph Edlyn Outridge, my executors, administrators, or assigns, should
at any time agree with, and no others, from. time to time and at all times there-
after during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
TRANSMITTING MOTIVE POWER," upon the condition (amongst others) that I, the
said Joseph Edlyn Outridge, by an instrument in writing under my hand and
seal, should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Joseph Edlyn Outridge, do hereby
declare the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying Drawings, and
to the letters and figures marked thereon; that is to say:-
My said Invention relates to a peculiar construction and arrangement
of mechanism, for transmitting a rotatory or partial rotatory motion when
required, whereby the use of toothed gearing is dispensed with. This im-

page_text: proved mechanism consists of two discs or circular open frames, keyed near
to each other on to a main driving shaft, and fitted near their peripheries
with a number of rollers, working in plummer blocks secured to the inner.
faces of the two opposing discs or frames, the axes of these rollers being in
the direction of the radii of the discs or circular frames. Between these discs'
is fitted, to revolve in suitable plummer blocks or bearings, a second shaft,
which is flattened, and then twisted slightly.at.the flattened portion, so as to
form a spiral of a large pitch upon it; or in place of flattening and twisting the
shaft, it may have a spiral blade or continuous incline formed upon it, and it is
upon this continuous revolving incline or spiral blade that the rollers carried
by the, discs operate during the revolution of the main driving shaft, by which
means a rotatory or only partial rotatory motion may be transmitted to the
second shaft, according to. the amount of rotation of the main driving shaft.
. And in order that my said Invention may be more properly understood, I.
shall now. proceed to describe and refer to the several Figures on the Sheet of
Drawings hereunto annexed.
Figure 1 of my Drawings represents a side elevation of one modification of
my apparatus as adapted for driving a screw propeller shaft; Figure 2 is a cor-
responding sectional plan, taken along the line 1, 2; in Figure 1; and Figure 3
is an end elevation of the apparatus, corresponding to Figure 1. The rest of the
Figures are details, which I shall herein-after more particularly describe and
refer to. A, A, are two opposed wrought or cast iron circular frames or
discs, somewhat similar to the frames of an ordinary paddle wheel. These
frames are keyed on to the main driving shaft B, which works in suitable
bearings C, C, on the cast-iron side standards D, D, which are firmly bolted:
down on to the bed plate E. The frames A are tied together by the adjusting
tie rods F, F, which are screwed at the ends, and fitted with jam nuts, so that
the distance between the two frames at all points of their circumference may
be accurately adjusted by simply screwing up or slackening the nuts on the tie
rods. G, G, are a number, of rollers, which may be made hollow for the sake
of lightness. These rollers work in the plummer blocks H, H, one of the
frames being partly broken away in Figure 1 to shew them more clearly.
These plummer blocks may either be bolted to or cast on to the frames A, A,
as found most convenient. The propeller shaft I works. in bearings in the
5 plummer, blocks J, J, which are 'bolted down on to the bed plate. This shaft
has a continuous rotatory motion imparted to it by the revolution of the frames
A, A, which cause the rollers G, G, to act upon each side of the spiral, or
twisted portion K, of the shaft. The action of the rollers G upon the propeller
shaft will be better understood on referring to the details, Figures 4 and 5-of

page_text: the Drawings. The height of the propeller shaft, or rather its distance from
the centre of the main driving shaft, is so regulated that its spiral or continuous
inclined portion K, shewn in dotted lines in Figure 1, sball always be embraced
between the several pairs of rollers G, as they are successively brought round
by the rotation of their carrying frames A; and the length of this spiral portion
is such as to admit of one pair of rollers commencing their action upon it at
the precise time that the preceeding pair are leaving it, so that their action
upon the spiral or continuous inclined portion of the propeller shaft may be
constant and regular. In Figure 4 the rollers G, G, are represented as having
traversed over one-half of the continuous incline, and in Figure 5 the same
pair of rollers are represented as just leaving it, whilst the succeeding pair of
rollers G¹, G¹, are commencing their action upon it. The spiral or continuous
inclined portion of the shaft, in place of being formed as shewn in Figures 4
and 5, by flattening a portion of the shaft, and then twisting such flattened
portion half a turn, by which means a double-threaded spiral will be formed,
may be made, as represented in Figures 6, 7, and 8, that is, with only a single
thread L formed upon it, such thread being acted upon on one side only, the
opposite roller to that which presses or bears against the thread or continuous
incline L bearing against the side of the shaft itself, as is clearly represented
in Figure 6, wherein the rollers are shewn as having passed over one-half of
the incline, whilst in Figure 7 they are represented as on the point of leaving
it, a succeeding pair of rollers having just commenced to operate upon the
incline. The transverse section, Figure 8, of the continuous inclined portion of
the shaft represents clearly the position of the incline L thereon. The straight
arrows in the details represent the direction of motion of the actuating rollers,
and the curved arrows the direction of rotation imparted to the propeller shaft.
In my Drawings I have represented the main driving shaft as being fitted
with a crank M at each extremity, at right angles to each other, such cranks
being connected to the piston rods of the oscillating cylinder engines N, N; but
may here observe, that I wish it to be distinctly understood that I lay no
claim to, neither do I confine or restrict myself to, this or any other mode of
driving or actuating my apparatus, as many modifications or arrangements may
be employed for that purpose, according to the different uses to which my
apparatus may be applied; and although I have only represented and described
my apparatus as applied to the driving of a screw propeller shaft, I may observe
that I propose employing it in all cases when applicable where a rotatory or
only partial rotatory or a reciprocating motion is required to be transmitted,
the motion transmitted being reversed by simply reversing the direction of
rotation of the frames or discs carrying the actuating rollers.
I

page_text: According to the arrangement shewn at Figures 1, 2, & 3 of the Drawings
the relative speeds of the driving and propeller shafts will be as three to one,
that is, the propeller shaft will make one-half a revolution for each successive
pair of rollers that pass over the continuous inclined portion of the shaft; con-
sequently, as there are six pairs of rollers in the discs or frames, the propeller
shaft will make three whole revolutions for one revolution of the driving shaft.
In case the rollers or continuous inclines should become warm by constant
working, and work too loosely together, the discs may be set up nearer together
by removing or slackening the keys which secure them to the driving shaft,
and tightening up the several tie rods, herein-before referred to.
Having now described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried
into effect, I would observe, in conclusion, that I do not confine or restrict
myself to the precise details or arrangements which I have had occasion to
describe or refer to, as many variations may be made therefrom without
deviating from the principles or main features of my said Invention; but
what I consider to be novel and original, and therefore claim as the Invention
secured to me by the herein-before in part recited Letters Patent, is, the
system or mode of transmitting a rotatory or partially rotatory motion by
means of rollers carried in circular rotatory frames or discs, and acting upon a
continuous incline or inclines on the shaft or portion of mechanism to be
actuated.
In witness whereof, I, the said Joseph Edlyn Outridge, have bereunto
set my hand and seal, the Fifteenth day of June, One thousand eight
hundred and fifty-five.
