PROVISIONAL SPECIFICATION.
Apparatus for Preventing or Minimizing Movement in a Rotary
Sense about their own Axes of Bodies being Carried Round by
Rotation of other Bodies to which they are Pivotted, and which
Apparatus is applicable inter alia as a Feathering Contrivance for
Paddle-wheel Floats.
I, CHARLES JOSEPH RIDSDALE, of St. Peter's Vicarage, Folkestone, in the
County of Kent, Vicar of St. Peter's, Folkestone, do hereby declare the nature of
this invention to be as follows:-
This invention has reference to apparatus for preventing or minimizing move-
ment in a rotary sense about their own axes of bodies being carried round by
rotation of the bodies to which they are pivotted, and which apparatus is appli-
cable, inter alia, as a feathering contrivance for paddle-wheel floats, and in order
that its nature may be understood, I will describe, by way of example, a paddle-
wheel float feathering contrivance constructed in accordance therewith.
Each float is fixed to a shaft mounted freely in the paddle-wheel,-at a suitable
angle (say rather more than a right angle) to each float shaft there is rigidly
attached to it one end of a telescopic or equivalent connection whose other end is
jointed to a disc or other device able to rotate about an axis at a suitable angle
(say somewhat more than a right angle) to that of the paddle-wheel shaft, from
which the said device is driven through suitable gear such as shafting and hevel
wheels, the arrangement being such that as the paddle wheel is rotated, so also
is the device to which the ends of the before-mentioned telescopic or equivalent
connections are attached, and thus those connections whilst retaining
the floats at all times approximately in parallel planes are enabled
to clear one another by travelling about an imaginary projection of
the axis about which the disc or its equivalent is rotated.
.
The disc or equivalent is situated at a distance from the paddle wheel shaft
(preferably aft of the paddle-wheel and is rotated in the contrary direction to
and and at a speed equal to that of the paddle wheel.
With this invention floats of greater width than heretofore usual may be in
some cases advantageously employed.
My invention is also applicable in various other cases where it is required to be
able to carry bodies round an axis without causing them at the same time to
rotate about their own axes, as for example in rope making cordeliers, wherein
my apparatus may be applied for the purpose of preventing rotation of the strand
bobbins or spools as they are revolved about the axis of the laying-block of the
machine.

I, CHARLES JOSEPH RIDSDALE, of St. Peter's Vicarage, Folkestone, in the
County of Kent, Vicar of St. Peter's, Folkestone, 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:-:
.)
This invention has reference to apparatus for preventing or minimising move-
ment in a rotary sense about their own axes of bodies being carried round by
rotation of the bodies to which they are pivoted, and which apparatus is appli-
cable, inter alia, as a feathering contrivance for paddle-wheel floats, and in order
that its nature may be understood, I will describie, by way of example, a paddle-
wheel float feathering contrivance constructed in accordance therewith.
T
Each float is fixed-to a shaft mounted freely in the paddle-wheel, at a suitable
angle (say rather. more than a right angle) to each float shaft there is
attached one end of a telescopic or equivalent connection whose other end is
jointed to a disc or other device able to rotate about an axis at a suitable angle
(say somewhat more than a right angle) to that of the paddle-wheel shaft, from
which the said device is driven through suitable gear such as shafting and bevel
wheels, the arrangement being such that as the paddle wheel is rotated, so also
is the device to which the ends of the before-mentioned telescopic or equivalent
connections are attached, and thus those connections, whilst retaining
the floats at all times, approximately in parallel planes are enabled
to clear one another. by travelling about an imaginary projection of
the axis about which the disc or its equivalent is rotated.
'
Referring to the accompanying illustrative drawings, Fig. 1 shows a plan of
a paddle-wheel embodying my float feathering contrivance and Fig. 2 shows a
side elevation with certain parts removed for the sake of clearness.
a, a are the paddle-wheel floats, 6 are the shafts on which they are fixed and
which are mounted freely in circumferential rims c, c of the sides of the wheel
at a suitable angle. ee,' are telescopic connections; each of these has one of its
ends rigidly attached to one of the float shafts b, the attachment being effected
by passing the end of the connection through a hole in the shaft and fixing by
suitable means such as a set screw d. The other end of each connection e is
jointed, by means of screw eyes f. to a disc g (near its periphery). The disc g
is fixed to a short shaft or axle g mounted at a suitable angle to the paddle-
wheel shaft in a bearing k carried by or formed in one with a bracket 7 fixed
to the side m of the vessel and adapted to be driven from the paddle wheel
shaft through suitable gear comprising a bevel wheel n mounted on such shaft,
hevel wheel o, shaft p. carried in brackets q fixed to the side m of the vessel.
bevel wheels r and s. shaft carried by hearings u fixed to or forming part of
the before mentioned bracket 7. and bevel wheels and w. As will be seen, with
this arrangement as the paddle wheel is rotated, so, also is the disc 7. conse-
quently the telescopic connections e whilst retaining the floats at all times. in
approximately parallel planes are enabled to clear one another by travelling
about an imaginary projection of the axis of the short shaft or axle g¹ about
which the disc 7 is rotated.

page_text: The disc g is situated at a distance from the paddle-wheel (preferably aft
thereof) and preferably at a higher level, and is rotated in such direction that
there is no distortion of the connections e and at a speed equal to that of the
paddle wheel, so that there is not any drag on the paddle wheel.
With this invention floats of greater width than heretofore usual may be in
some cases advantageously employed.
The details of construction may obviously be varied, (for examples, the attach-
ments may be ball and socket joints, the disc g may be formed as a star wheel),
as also may the arrangement of the parts and the means for driving the disc g.
My invention is also applicable in various other cases where it is required to be
able to carry bodies round an axis without causing them at the same time to
rotate about their own axes, as for example in rope making cordeliers wherein
my apparatus may be applied for the purpose of preventing rotation of the strand
bobbins or spools as they are revolved about the axis of the laying-block of the
machine, in which case the axis of the laying-block would take the place of the
paddle wheel shaft h and the bobbins or spools would take the place of the floats a.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is:-
1. For preventing or minimizing movement in a rotary sense about their own
axes of bodies carried round during rotation of a body to which they are pivoted,
the combination of telescopic or equivalent connections secured to the pivots or
axles of the bodies whose rotation is to be prevented, and a controlling disc or
device caused to rotate in unison with the said rotating body substantially as
described.
2. Apparatus substantially as described for controlling pivoted bodies during
rotation of the body or structure to which they are pivoted.
3. In a paddle wheel controlling the floats substantially as described.
4. For controlling floats or other bodies pivoted to a wheel or other rotary
body apparatus constructed arranged and operating as described and illustrated.
