PROVISIONAL SPECIFICATION left by the said Jolin Whitaker at the
Office of the Commissioners of Patents, with his Petition, on the
28th July 1875.
I, JOHN WHITAKER, of Rhuddlan, near Rhyl, in the County of
Flint, North Wales, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN CHAFF CUTTING MACHINES, WHICH IMPROVEMENTS ARE
APPLICABLE TO OTHER DESCRIPTIONS OF MACHINERY," to be as follows:-
The Invention relates primarily to a novel arrangement and com-
bination of parts whereby facility is afforded in chaff cutting machines
for feeding at different speeds, for reversing and for stopping the feed,
but is also applicable to the driving or feeding motion of other

page_text: machinery For this purpose I mount loosely on the main or driving
shaft of the machine three bevilled pinions, and on a cross shaft I key
or otherwise fix a wheel having two rings of bevilled teeth formed
thercon Into the smaller of these rings of teeth, or in some cases it
might be the larger, two of the bevilled pinions goar, the one on the
one side and the other on the other side of its axis of motion, whilst
the third bevilled pinion gears with the larger or other ring of teeth.
Intermediate of the two fust-mentioned bevilled pinions is mounted on
the driving shaft a double clutch, which is capable of sliding thereon
endwise, but is compelled to rotate therewith. This double clutch is
capable of being thrown into gear with either of the pair of bevilled
pinions, or of being placed in a position intermediate thereof. Another
clutch is mounted on the driving shaft in a similar manner with
capability of being thrown into gear with the third bevilled pinion.
The double clutch and the single clutch are cach thrown into and out
of gear or connection with the various bevilled pinions by means of fork
levers mounted on axes of motion and acting in combination with
suitable clutch boxes.
On the axis of the lever operating the double clutch is keyed or
otherwise fixed a lover, by means of which the double clutch may be
made to engage with either of the pair of bevilled pinions in order
to operate the feed motion or drive the machine forwards or back-
wards.
•
The other clutch lever is operated by a slide pin jointed thereto.
This slide has fixed on the end near to the lever operating the double
clutch a cross piece, on which is fixed a pin by which it is operated by
a suitable forked lever having a handle or operating lever fixed on the
axis thereof. The lever working the double clutch is extended in both
directions from its axis, and is capable of acting upon the aforesaid
cross piece to throw the single clutch out of gear with the third bevilled
pinion whenever the double clutch is thrown into gear with either of
the pair of bevilled pinions, whilst whenever the single clutch is thrown
into gear with the third bevilled pinion the cross piece acts upon thic
lever operating the double clutch to place the latter in a midway
position between the pair of bevilled pinions.
It is evident that the clutches may be operated by treadles instead of
hy hand ne will be well understood

page_text: By the aid of my Invention I am enabled in chaff cutting machines
to place the various pinions by which the different speeds and reversing
motion are obtamed all on the same or driving shaft, whilst in other
machinery, although the various pinions are mounted on the same shaft,
they may in some cases be mounted on the secondary or driven shaft
instead of on the main shaft
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Whitaker in the Great Scal Patent Office
on the 28th January 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WHITAKER, of Rhuddlau, near Rhyl, in the County of Flint, North
Walos, send greeting.
WHEREAS Пer most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the Twenty-eighth day of July, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of or reign, did, for Herself, Her heirs, and suc-
cessors, give and grant unto me, the said John Whitaker, Her
special licence that I, tho said John Whitaker, my executors,
administrators, and assigns, or such others as I, the said John
Whitaker, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might
make, use, excrcise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an In-
vention for "IMPROVEMENTS IN CHAFF CUTTING MACHINES, WHICH IMPROVEMENTS
ARE APPLICABLE TO OTHER DESCRIPTIONS OF MACHINERY," upon the condition
(amongst others) that 1, the said John Whitaker, my executors or admı-
nistrators, by an instrument in writing under my, or their, or one of
their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to
be performed, and cause the same to be filed in the Great Scal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said John Whitaker, do hereby
declare the nature of my said Invention, and in what manner the
samo is to be performed, to be particularly described and ascertained
in and by the following statement
-
The object of this Invention consists primarily in a novel arrange-
ment and combination of parts whereby facility is afforded in chaff
cutting machines for feeding at different speeds, for reversing, and for
stopping the field, but is also applicable to the driving or feeding
motion of other machinery To effectuate the above I mount loosely
on the main or driving shaft of the machine three bevilled pinions, and
on a cross shaft I key or otherwise fix a wheel having two rings of
bevilled teeth formed thercon Into the smaller of these rings of teeth
(or in some cases the larger) two of the bevilled pinions gear, the one
on the one side and the other on the other side of its axis of motion,
whilst the third bevilled pinion gears with the larger or other ring of
teeth. Intermediate of the two first-mentioned bevilled pinions is
mounted on the driving shaft a double clutch, which is capable of
sliding thereon endwise, but is compelled to rotate therewith. This
double clutch is capable of being thrown into gear with either of the
pair of bevilled pinions or of being placed in a position intermediate
thereof. Another clutch is mounted on the driving shaft in a sımılar
manner with capability of being thrown into gear with third bevilled

piece K O, O¹, arc handles secured to axes or spindles of the lever F
and forked lever M for throwing the clutches in and out of gear.

Having now particularly described and ascertained the nature and
object of the said Invention and in what manner the same is to be
performed or carried out in practice, I hereby declare that I claim the
Invention of "Improvements in Chaff Cutting Machines, which Im-
provements are Applicable to other Descriptions of Machinery," as the 1
same is herein-before set forth and described in this Specification by
the words preceding the Description of the Drawings, such Invention
being illustrated for the better exemplification thereof by the accom-
panying Drawings herein-before descriptively referred to, it being
understood that I do not claim nor do I limit myself to the use of the 2
constructive details hercin-before described, as the same may be varied
without substantially departing from the nature and character of my
said Invention, as the same is herein-before set forth and described
In witness whereof, I, the said John Whitaker, have hereunto
set my hand and seal, this Twenty-sixth day of January, in the 2
year of our Lord One thousand eight hundred and seventy-six.
