Improvements in Windmills.
RICHD. MATTHEWS Merchant. Marazion Cornwall, 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 relates to improvements in windmills as machines to make use of
the wind for supplying motive power for mining and agricultural purposes, such as
pumping, grinding etc., etc., also as motors for electric lighting & has for its
object: :―
First, the improved construction and arrangement for raising or lowering the
rudder.
Second To making the iron frame work in parts.
According to the first part of my invention I make the lower end of the frame
which carries the connections of the rudder and in which the rudder revolves to be
adjustable by means of a screwed eye-bolt for the purpose of raising or lowering
the tail or outer-end of the rudder so as to set it to any suitable angle to realize
the most effective force of the wind for regulating the working of the mill or
machine, thus dispensing with such complicated regulating appliances as ball
governors, vanes etc., as now in use.
According to the second part of my invention I arrange the iron frame work in
parts so fitted & bolted to the frame work that each part may be easily taken off
separately in case of breakage & replaced without the inconvenience of taking
down the whole iron frame work as is now the case. This has particular reference
to the two standards which carry the rollers & in one of these standards the rudder
is secured.
This invention will be best understood by reference to the accompanying
drawings.
Fig. 1, is a vertical section and Fig. 2 is a plan of the mill or machine.
A. is the mill wheel & when in work gives the shaft B, to which it is securely
fixed & which works in the bearings C. C. C. a rotary motion, & this motion is
conveyed to the upright main driving shaft, D, by the means of the bevil
wheels E. E. & at the lower end of this main driving shaft D, connections are
fixed suitable for the purposes to which the mill may be applied. F. F. are the
wood supports on the top of which the foundation collared plate or bed G is fixed
& on which the top frame work H. revolves. I. is the part that is bolted on to
the iron frame work H. and carries the rudder J. On the top of this part I. is
fixed the roller L. similar to the roller L' in the part M. which is the other part
to be bolted at N to the top frame work, H. These rollers carry the rope or chain
for regulating the rudder J. when it is necessary.
Fig. 3, shows the frame or part I. having the screwed eye-bolt I¹ at the bottom
for raising & lowering the tail or outer-end of the rudder, J, & is one part to be
bolted at O, to the top frame work, H.
Fig. 4, is the other part M, that carries the roller L' & is bolted to the top frame
work at N.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is,―
First. The improved construction and arrangement for raising & lowering the
rudder of wind-mills substantially as described and with reference to Fig. 3 of the
accompanying drawing

page_text: Second. To making the top iron frame work in parts substantially as described
and with reference to Figures 3 & 4 of the accompanying drawings.
