I Claim.
(01. 170-107) '
_ This invention relates to ?uid motors: and more
pontoons Ill andxa'hawser I3 is connected at
particularly to a motor or power member which is
one end, as at I4, to? the convergent. forward ends
of the braces I2 and the opposite end of the
hawser vIt is adapted to be. connected to a suit
able point, such as a post, tree or the like along‘
adapted to be positioned in a moving" stream of
water.

object of this invention is to provide a
machine or motor of this kind which can be‘po
the shore of a. moving stream of water..
‘
sitioned in a. moving stream of‘ water in such a
A guide line I5 is connected at. one end to one
manner that the position of the ‘motor in the
stream may be varied at will so that the device
1c will readily perform its functions notwithstand
ing any shifting of the bed of the water and
of the pontoons In and the other end‘ of the
guide line. I5 is connected, as at I6, to the. hawser
notwithstanding any riseor fall of: the water.»
"Another object of this. inventionyis: to provide
in a current motor, means for“ supporting the
is motor relative to‘the water so. that, when desired,
the. motor may be quickly removed from or re
placed in the water, thus making it‘possible to
position the motor or machine at a point out
wardly from the shore line of the moving‘ body
or holding member I3, so that the twopontoons 10
illv will be maintained; in a position longitudinally
of the movement‘ 'of' the stream of water. Each
pontoon I0 is provided with a keelv II'I at the
bottom thereof soas to prevent. lateral'swinging
movement of these pontoons in. the water.
15
A motor frame;.generall’y designated as I8, is
disposed between the two pontoons' I0 and. be
tween the end connecting bars I I‘. This frame I8
comprises side bars I9 and end bars 2|] forming a
of water and making. it possible to- quickly. re- ‘ substantially rectangular frame slightly smaller 20
move the machine from the water‘ so as to pre-' in size than the distance between'the two pon
toons and the distance between the end con
vent damage to the machine, as during the move
necting members. I“I.' The frame I8 has a plu
ment of ice in the water or during flood‘ condi
tions'.

A further object of ‘this invention is. to provide

Referring to the drawing, the numeral I0 des
_ ignates generally a pair of pontoons or like buoy
50 ant members which are disposed in parallel
spaced apart relation and held in such relation
by means of connecting bars II, which connect
the opposite ends of the pontoons I0 together.
A pair of forwardly extending braces or draw
55 ‘bars I2 are secured to the forward ends of the

be disposed within the motor frame I8. The
offset portions of the cranks 25 are connected to
gether as by an elongated pitman 21 and this
pitman 21 is adapted to be connected through a
suitable connecting means to a driving shaft.
41]:
. There are two of thesepitmans 21, one on each
side of the frame I8, so that in the rotation of
the wheels '2I there will not be‘ any tendency
for these wheels to twist by reason of the strain
placed on one end thereof;
45
The frame I8 with the paddle wheels 2|
mounted therein is supported'between the pon
toons III by means of ?exible supporting mem
bers 28 and 29. These ?exible members 28 and
29 are ropes or~ cables provided with a V-shaped
portion,‘ secured tothe ends 20 of the frame
‘I8, and the ropes or ?exible members 28 and
29 are then wound about a winding shaft 30
which is journalled, ‘as at 3|, in upwardly con»
verging bracing ,or supporting members 32. I The 55

supporting members 32 are secured at their di
vergent lower ends to the pontoons ID or to the
end braces II and, if desired, a suitable pawl and
ratchet may be associated with the shaft 30 so
that when the shaft 30 is turned to wind the

the use of this construction the rotation of the
paddle wheels is not effected by wind as the

These ropes 28 and 29 may also be used to deter
