page_text: I, WILLIAM SUTHERLAND of 26 Skene Street, Macduff, N.B. Traction Engine
Driver and Part Owner, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a straw elevator particularly applicable for use in con-
nection with Steam thrashing mills and has for its object to provide a light,
efficient and easily managed machine and which can be readily moved from place
to place.
In carrying out my invention I employ a body of any suitable shape and mount
it upon wheels so as to enable it to be moved when desired, the said body may also
have means for attaching it to the thrashing mill.
. Upon the top of the body and at any suitable distance from the end I secure
two brackets, one at each side, upon which a wooden or other shoot is mounted,
the shoot being secured to a shaft which passes between the brackets in such a
manner that it can be set at any desired angle and when not required can be laid
upon the body of the machine. The shoot is composed of two, three, four or more
sections hinged together so that when laid upon the body of the machine it can
be folded up so as not to project beyond the end of the machine, when it is packed
for travelling.
The shoot is also provided with chains and sprocket wheels, one mounted at each
side, to which chains suitable rakes are secured at any required distances for
catching the straw, the said rakes extending across the shoot.
The shaft upon which the sprocket wheels are secured, which is the same as that
upon which the shoot is mounted, is provided at its end with a spur wheel, the
said wheel being driven by means of suitable gearing carried by a second shaft,
this second shaft carrying the driving pulley which is operated from the mill
by a belt.
Small guide wheels are secured at suitable distances to the underside of the
shoot for guiding the chains.
The top of the shoot may also be provided with a support for resting against a
building etc.

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:―
This invention relates to a straw elevator particularly applicable for use in
connection with steam thrashing mills and has for its object to provide a light
efficient and easily, managed machine which can be readily moved from place to
place.
But in order that my said invention may be more readily understood and easily
carried into effect I will proceed to describe the same with reference to the accom-
panying drawings in which
Fig. 1 is an elevation of part of a thrashing mill with the straw elevator attached.
Fig. 2 is a plan of the same.
Fig. 3 is an elevation of the elevator when packed for travelling.
Referring to the said drawings I employ a body A of any suitable shape and
mount it upon wheels a so as to enable it to be moved when desired; the said
wheels being secured in adjustable bearings a¹ so that the body can be kept level.
The said body may be attached to the mill by metal pins a² or other similar means
enabling it to be detached when required.
Upon the top of the body, A. and at any suitable distance from the end I secure
two brackets B, one at each side upon which a wooden or other shoot C is mounted,
the shoot being secured to a shaft 6 which passes between the brackets B so that it
can be set at any required angle and when not required can be laid upon the
body A. The shoot is composed of two, three, four or more sections provided at c
with hinges of any convenient form arranged upon the upper and under parts of
the shoot alternately, to enable the shoot when laid upon the body of the machine
to be folded up (as shewn more particularly in Fig. 3) so as not to project beyond
the body when packed for travelling.
The shoot is also provided with chains D and sprocket wheels d; to which
chains D, suitable rakes E are secured at any required distances for catching the
straw, the said rakes extending across the shoot. A hopper D₁ is also provided
arranged to catch the straw as it issues from the mill.
The shaft upon which the sprocket wheels d are keyed, and which also carries
the shoot, is provided at its end with a spur wheel d¹ driven by means of suitable
gearing, such as spur and bevel or mitre wheels arranged as shewn, rotated by a
shaft b mounted upon the body A; this shaft & also carrying the driving pulley F
which is operated from the mill by a belt.
In order to allow the shoot to be swung or rotated from side to side I secure
the carrying brackets B to a ring G arranged to work upon a similar ring G¹
permanently fastened to the body A, the said rings being held together by means
of a number of brackets or slip pieces g provided with friction rollers gl.
Small guide wheels H are secured at suitable distances to the underside of the
shoot for guiding the chains D.
To further reduce the bulk when the shoot is folded for travelling I may hinge
the sides of one or more of the sections so that they can be folded inwards or other
wise and allow them to lie more closely together.
J represents a small hand crane or winch for raising and lowering the shoot
and K is a wind protector which may also be hinged so that it can be folded.
A second rope on the crane or winch may be employed for folding and unfolding
the machine.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
A straw elevator, for use particularly with thrashing mills for elevating the

page_text: straw as it issues therefrom to the stack or other place, constructed and operating
in the manner as hereinbefore described and shewn in the accompanying drawings.
