the County of Berks, Engineers, for the Invention of "IMPROVEMENTS IN
THRASHING MACHINES, AND IN APPARATUS CONNECTED THEREWITH."
PROVISIONAL SPECIFICATION left by the said Thomas Nalder and
William Nalder at the Office of the Commissioners of Patents on the 22nd
November 1878.
THOMAS NALDER and WILLIAM NALDER, both of Challow, in the County of
Berks, Engineers. "IMPROVEMENTS IN THRASHING MACHINES, AND IN APPARATUS
CONNECTED THEREWITH."
Our Invention relates to an improved construction of combined portable thrashing
and straw elevating apparatus.
In carrying out our Invention the straw elevating apparatus is affixed on the
straw delivery end of the thrashing machine, and is of such a construction that it
can be adjusted so as to deliver the straw either straight with or in an angular
direction on either side of the machine, and this adjustment can be made when the
elevator is working or not.
The receiving end of the straw elevator trough is mounted on a horizontal axis,
allowing of the raising and lowering, and on a vertical axis, which allows a lateral
or side motion of the delivery end of the elevator.
The gear or arrangement for giving motion to or setting the elevator to work is
so arranged that the operation of raising or lowering, or the lateral or side motion
can one or both be performed without stopping the working of the elevator.
The apparatus is also so constructed and arranged that the delivery end of the
[Price hd 1

page_text: elevator can be raised or lowered when in the straight or angular direction by
means of ropes or chains or their equivalents passing over or round guides, which
are placed in a vertical line with the vertical axis, on which the elevator rotates or
partially rotates, or round guides otherwise arranged so as to allow of the lateral or
side motion of the elevator.
These devices may also be used in the operation of packing up the elevator for
storage or travelling.
The thrashing and straw elevating apparatus, when either packed up or when
set ready for work, or when at work, forms one complete machine, which is mounted
on a set of four travelling wheels.

Berks, Engineers. 'IMPROVEMENTS IN THRASHING MACHINES, AND IN APPARATUS
CONNECTED THEREWITH.”
Our said Invention relates to an improved construction and arrangement of
combined portable thrashing and straw elevating apparatus.
In carrying out our said Invention the straw elevating apparatus is affixed on
the straw delivery end of the thrashing machine, and is constructed and arranged
in such a manner as to admit of its being adjusted so as to deliver the straw either
straight with or in an angular direction on either side of the machine, and so as to
enable such adjustment to be effected either when the elevator is at rest, or when it
is in operation.
The receiving end of the trough of the straw elevator is mounted on a horizontal
axis, which admits of the delivery end of the trough being raised or lowered, and
on a vertical axis, admitting of a lateral or side motion of the delivery end of the
said trough,
The straw elevating gear is so arranged and actuated, and the apparatus generally
is so constructed and arranged that the operation of raising or lowering the elevator,
or of adjusting it laterally, or both operations can be performed without stopping
the working of the elevator, and that the delivery end of the elevator may be raised
or lowered when in the straight or angular direction.
The raising or lowering of the elevator is effected by means of ropes or chains
or their equivalents passing over or round guides, which are placed in a vertical
line with the vertical axis, on which the elevator rotates or partially rotates, or
round guides otherwise arranged, so as to allow of the lateral or side motion of the
elevator.
The thrashing and straw elevating apparatus, when either packed up or when set
ready for work or when at work forms one complete machine, which is mounted on
a set of four travelling wheels.

page_text: And in order that our said Invention may be fully understood, we shall now
proceed more particularly to describe the same, and for that purpose shall refer to
the several Figures on the annexed Sheet of Drawings, the same letters of reference
indicating corresponding parts in all the Figures.
Figure 1 of the accompanying Drawings represents a side elevation of a combined
thrashing and straw elevating machine, constructed in accordance with our said
Invention, and mounted on its own travelling wheels, the apparatus being repre-
sented in one position for work. Figures 1 and 1b are respectively longitudinal
and transverse sections of a portion of the apparatus.
Figure 2 is a plan of the straw elevating apparatus, with a portion only of the
thrashing part of the machine; the dotted lines show the straw elevating apparatus
at various angles relatively to the thrashing part of the machine.
Figure 3 is a side elevation of the combined thrashing and straw elevating
machine, the apparatus being represented as packed up for travelling and mounted
on its own travelling wheels.
A is the main frame of the thrashing machine, having formed thereon or attached
thereto a table or platform B, the upper portion C of which is mounted so as to
be capable of rotation or partial rotation on a pivot 1 around the axial line a, a.
To this upper portion is attached the lower end of the elevating trough D with
the hopper Di; this attachment is effected by jointing the elevating trough D to
the portion C by means of joints or hinges E, thus forming a centre upon which
the lower end of the trough D may turn, so that the delivery end of the said trough
may be raised or lowered as required.
In order to enable the trough to be turned upon its joints or hinges E with
facility, a crane or winch F is employed, and suitable guides G, G, are provided,
over which is passed a rope or chain b, wound at one end upon the drum of the
crane or winch, and connected at its opposite end to other chains b', b', attached to
the delivery end of the trough.
By the act therefore of operating the crane or winch F, and thereby winding
upon or unwinding from the drum of the same the rope or chain b, the delivery end
of the trough D is raised or lowered, as the case may be.
If desired the crane or winch may be so arranged as to be capable of rotating or
making a partial rotation on a pivot or axis situate on the axial line a, a, round
which the upper portion C of the table or platform B rotates.
The rotatory motion of the upper portion C of the table or platform B carrying
the trough D may be obtained by means of a worm I and worm wheel K, or any
other suitable arrangement, or without any special devices for the purpose, and when
the crane or winch is also arranged so as to be capable of rotatory motion, as before
mentioned, such combined motion of the crane or winch, and of the upper portion C
of the table or platform, may likewise be imparted by the aid of a worm and worm
wheel or other suitable means, which in that case is connected with the crane or
winch.
In an axial line with the joints or hinges E is a spindle E', on which and on a
spindle L at the opposite end of the trough are respectively secured drums or pullies
E; over these drums or pullies pass endless webs, belts, or chains M, M, on which are
secured prongs or rakes, which in the example illustrated are attached separately to
each web, belt, or chain.
Motion is imparted to these webs, belts, or chains by means of a pair of spur
wheels 01, 0, and the belt N, which passes over the pullies O, P, P, Q, as will be
well understood. When it is required that the prongs or rakes should be attached
to both of the webs, belts, or chains M, M, the inner or lower drums or pullies may
be mounted on a separate spindle driven from the spindle E¹ in any convenient
manner.
It will be seen that by means of the arrangements hereinbefore described the
elevator may be adjusted so as to deliver the straw either straight with, that is to
say, in a line with a machine, in which position it is indicated by full lines in the
Drawings (Figures 1 and 2), or in any required angular direction on either side of

page_text: '
the machine, examples of which angular positions are denoted by dotted lines in
Figure 2. The elevator is also capable of motion round its horizontal axis, whereby
facility is afforded for adjusting the elevator to any required angle of inclination in
a vertical plane by raising or lowering the delivery end of the trough, and this
operation may be performed when the elevator is in its straight position or in any
of its side angular positions. By reason moreover of the mode of mounting the
clevator, and transmitting motion to the straw elevating gear, the adjustment of
the elevator round its vertical axis, or its horizontal axis, or round both axes, may
be effected either when the elevator is at rest or while it is in operation.
In order to assist in retaining the apparatus in any adjusted position, props R
may be employed, the length of which is capable of adjustment according to the
required height of the delivery end of the elevator; or in lieu of employing props,
ropes or chains may be used or fastened to any convenient fixture or to pegs driven
into the ground.
For the purpose of facilitating the packing up of the elevating trough for travel-
ling, as indicated in Figure 3, the sides D3 of the trough may be made in two or
more convenient parts, as shewn, and so arranged as to be capable of being detached
from the joints or hinges E, on which they are mounted when in position for
work.
The sides D³ may also be made separate from the flooring S, which may also be
made in two or more parts, as in the example illustrated, or the flooring may be
hinged together in two or more sections, or the flooring and sides bodily may be
hinged together in two or more sections, if desired.
Having now described and particularly ascertained the nature of our said Inven-
tion, and the manner in which the same is or may be used or carried into effect,
we would observe in conclusion that we do not confine ourselves to the precise
details of the apparatus herein before described, as the same may be varied without
departing from the principle of the said Invention, but what we consider to be
novel and original, and therefore claim as the Invention secured to us by the
herein before in part recited Letters Patent is,―
The combination with a thrashing machine of a straw elevator pivotted to the
machine, and arranged in such a manner as to admit of the elevator being adjusted
to any required horizontal and vertical angle relatively to the thrashing portion of
the machine, either when the clevator is at rest or when it is in operation, the
combined apparatus being self contained or mounted on one and the same set of
travelling wheels, all substantially as herein-before described.
In witness whereof, I, the said Thomas Nalder, on behalf of myself and the
said William Nalder, have to this our Specification set my hand and seal,
this Fifteenth day of May, One thousand eight hundred and seventy nine.
