Engineers do hereby declare the nature of this invention to be as follows:-
The object of our invention is to facilitate access to the dressing apparatus of
thrashing machines more especially to the second dressing apparatus and consists
in mounting the casing of the blower or fan or the said casing together with the
fan itself upon a vertical or approximately, vertical hinge joint or pivot in such a
manner that it or they can be turned or opened horizontally or approximately

COMPLETE SPECIFICATION.
Improvements in Thrashing Machines.
We THOMAS NALDER, WILLIAM NALDER and ERNEST THOMAS WILSON
NALDER, all of The Challow Iron Works, near Wantage, in the County of Berks,
Engineers, 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 :-
The object of our invention is to facilitate access to the dressing apparatus of
thrashing machines more especially to the second dressing apparatus and consists
in mounting the casing of the blower or fan or the said casing together with the
blower or fan itself upon a vertical or approximately vertical hinge joint or pivot
in such a manner that it or they can be turned or opened horizontally or
approximately horizontally upon the said hinge, joint or pivot, to give access to
the dressing apparatus.
Figure 1 shews in end elevation and Figure 2 in side elevation so much of a
thrashing machine as is necessary to illustrate a practical application of our
invention. We have shewn what we consider the best arrangement but we do not
limit ourselves to the precise details shown.
a is that portion of the thrashing machine which is known as the second or
upper dressing and sifting apparatus to which it is desirable to have ready means
of access for examination, shifting of sieves or other purpose. B is the blower or
fan connected with this said second dressing apparatus and arranged so as to blow
directly into the interior of the thrashing machine. The said blower or fan is
mounted in bearings in its casing B2 which casing has knuckles b through which
and through knuckles 62 on the body of the machine passes a pin 63 so as to
constitute a vertical or approximately vertical hinge joint upon which the casing
and the blower or fan carried by it can be turned in a horizontal or approximately
horizontal plane so that the dressing or sieving apparatus can be readily examined,
or shifted, at the opening through which the spout of the blower or fan projects
into the machine.
c is an upper cover of the casing which can be fixed on to the blower or fan
casing or be hinged to the machine so that it can be turned up when the casing and

page_text: blower or fan are to be turned on their hinge joint. d is a catch which holds the
casing and blower or fan in the closed position.
We have shown the blower or fan and its casing as being at the end of the
machine so as to blow longitudinally thereinto but the said blower or fan and casing
may be arranged in other suitable position for instance at the side of the machine
so as to blow into the interior of the machine transversely.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
--
In thrashing machines a blower or fan casing or casing and blower or fan
mounted so as to be capable of being turned upon a vertical or approximately
vertical hinge joint or pivot substantially as and for the purpose hereinbefore
described.
