page_text: desirable to obtain a rapid speed at the delivery point. The power may be transmitted
from the shaft B by means of any suitable transmitting mechanism. As shown in
this instance the shaft B is provided with one or more large pulleys F which also
serve as a fly wheel and are connected by a belt f with a pulley g which as shown in
fig. 1 operates a crank shaft connected by a pitman H with the piston of an air
compressing cylinder & that may be employed if desired to compress air into a
reservoir supported either on the float itself or at any convenient point and connected
with the compressing engine by a suitable conduit having a flexible portion to
accommodate the rise and fall of the float.
As shown in figs. 1 and 2 the winding drum and cables are located near the centre
of the float which is provided with a well through which the cables pass but obviously
the arrangements may be such as to comprise a series of cables with shafts and
stationary framework located at different points relatively to the float and in the
construction shown in fig. 3 the float is provided with two shafts which extend to the
outside of the float and are there provided with drums to engage two sets of cables.
Such construction insures the guidance of the float and insures equalization of the
force acting on said shafts as was effected by the rack and pinion construction
forming the subject of the application hereinbefore referred to wherein said mechanism
is specifically claimed.
The present invention is not however limited to any specific form of machinery
supported on the float and actuated by the upward and downward movement thereof
nor of the adjacent and connecting mechanism by which the upward and downward
movement is converted into a more rapid rotary or reciprocating movement; obviously
instead of the cables wound about the drum as shown a chain belt may be employed
the links whereof engage projections on the surface of the drum.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by my
foreign correspondent I declare that what I claim is ;-
1. In a tidal motor the combination of a floating structure that rises and falls with
the tide mechanism supported on said floating structure and rising and falling there
with a stationary structure located in proximity to the float and intermediate
connections engaging with the stationary structure and with said mechanism whereby
the latter is actuated in the rise and fall of said floating structure substantially as
described.
2. In a tidal motor the combination of a float that rises and falls with the tidė
mechanism supported on said structure and rising and falling therewith a stationary
structure located in proximity thereto and intermediate cable connections whereby
the mechanism is actuated in the rise and fall of said float substantially as
described.
3. In a tidal motor a floating structure that rises and falls with the tide and a
stationary structure in proximity thereto with shafting flexible connections intermediate
the float and stationary structure engaging said shafting for the purpose of rotating
the same in the rising and falling movement of said floating structure substantially
as described.
