AN IMPROVED FARM-YARD DUNG OR MANURE SPREADING MACHINE AND DISTRIBUTOR
Year: 1875

page_text: LETTERS PATENT to John Pamphilon, the younger, of Whittlesford,
in the County of Cambridge, Wheelwright, for the Invention of
"AN IMPROVED FARM-YARD DUNG OR MANURE SPREADING MACHINE AND
DISTRIBUTOR."
PROVISIONAL SPECIFICATION left by the said John Pamphilon at
the Office of the Commissioners of Patents, with his Petition, on
the 29th June 1875.
I, JOHN PAMPHILON, the younger, of Whittlesford, in the County of
Cambridge, Wheelwright, do hereby declare the nature of the said
Invention for "AN IMPROVED FARM-YARD DUNG OR MANURE SPREADING
MACHINE AND DISTRIBUTOR," to be as follows:-
The object of my Invention is to attach to a cart or waggon laden
with farm-yard manure an apparatus which will evenly distribute the
manure over the surface of the land, while the cart or other vehicle
(with the apparatus attached thereto) is drawn over the ground,

page_text: The apparatus consists of an open box mounted on wheels and
provided at bottom with a travelling endless platform consisting of
transverse slots attached to endless chains, which pass over and are
actuated by two pairs of spiked wheels. Above this travelling endless
platform is mounted a transverse shaft or axle around which are
arranged helically, and extending from end to end of the shaft a number
of spikes, which when the shaft is rotated will serve to stir up or agitate
the manure and spread it evenly on the travelling endless platform.
The axle of the running wheels passes below the bottom of the box in
which the endless travelling platform works, and on one end of this
axle between the running wheel and the side of the box is adapted a
clutch carrying a large spur wheel, which gears into and drives a smaller
toothed wheel or pinion on one side of the horizontal spiked shaft or
agitator, so that as the apparatus is drawn forward over the land the
spiked shaft or agitator is made to rotate quickly and stir up and agitate:
the manure much in the same manner as the spiked shaft of a hay-
making machine tosses or throws about the hay.
In order that the manure may not be thrown out of the box the
agitator is covered over by an open grating of a curved or any other
convenient form. On the other end of the running wheel axle is another
toothed wheel provided with a clutch, whereby it may be thrown in or
out of gear with a similar but larger wheel upon the axle of one of the
pairs of spiked wheels, whereby the endless chains of the travelling
platform are actuated.
The axle of the front pair of spiked wheels is mounted in adjustable :
boxes which are capable of being moved in slotted bearings by means of
adjusting screws, so as to loosen or tighten the endless chains round the
spiked wheels as may be required.
At the front part of the apparatus is an inclined board or shoot on to
which the manure is drawn from the tail of the cart, to which the a
apparatus is attached by chains or otherwise. A small steering wheel is
adapted to the front end of the apparatus and supports that part.
On the top of the manure box is placed a raised platform for the
attendant to stand upon. It is surrounded by a railing to prevent him
from being thrown off by accident when the apparatus is jolting over a
rough ground. This railing also serves to support a pair of rods (one on
each side), whereby the clutches on the axle of the running wheels may

page_text: be worked, when it is desired to throw the toothed driving wheels in or
out of gear with the working parts.
This manure spreading or distributing apparatus having been tem-
porarily attached to the manure cart as already mentioned, and brought
into the field where the manure is to be spread; the workman operates
in the following manner :-He places himself on the raised platform
above the distributor and by means of a fork, rake, or other suitable
implement he drags the manure in suitable quantities from the cart on
to the inclined shoot of the spreader, and from thence on to the endless
travelling platform which carries it forward to the rotary agitator. The
quantity of manure which is allowed to pass into the apparatus is
regulated by means of an adjustable inclined slide, which may be raised
or lowered as may be required.
Upon the several working parts being thrown into gear, the travelling
platform (on the apparatus being moved forward on the land) will be set
in motion by the running wheels. At the same time the spiked shaft or
agitator will be rapidly rotated, and will lift the manure from the
travelling platform and will toss it up and throw it on to the after or
rear part thereof, on which it will be evenly spread. The platform by
continuing to rotate or travel forward will drop the manure out of the tail
of the apparatus, and evenly distribute it over the surface of the ground
as the apparatus is drawn forward.
The operations of the rotating agitator or the endless travelling plat-
form may be instantaneously stopped by throwing the corresponding
clutch out of gear by means of the rods or handles provided for the
purpose.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Pamphilon in the Great Seal Patent Office
on the 29th December 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
PAMPHILON, the younger, of Whittlesford, in the County of Cambridge,
Wheelwright, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-ninth day of June, in the year

page_text: spiked wheels or octagonal box wheels d, d, as shown in the Drawing.
Above this travelling endless platform c is mounted a transverse shaft or
axle e, around which are arranged helically and extending from end to
end of the shaft a number of spikes, prongs, or tines e', e', which when
the shaft c is rotated will serve to stir up or agitate the manure, and
The axle b' of the
spread it evenly on the travelling endless platform c.
running wheels b passes below the bottom of the box a in which the
endless travelling platform c works, and on one end of this axle between
the running wheel and the side of the box a is adapted a clutch f
carrying a large spur wheel f', which gears into and drives a smaller
toothed wheel or pinion g on one side of the horizontal spiked shaft or
agitator e, so that as the apparatus is drawn forward over the land, the
the spiked shaft or agitator e is made to rotate quickly, and stir up and
agitate the manure much in the same manner as the spiked shaft of a
haymaking machine tossos or throws about the hay.
In order that the manure may not be thrown out of the box the
agitator is covered over by an open grating ½ of a curved or any other
convenient form. On the other end of the running wheel axle b' is
another toothed wheel i provided with a clutch j, whereby it may be
thrown in or out of gear with a similar but larger wheel k upon the axle
of one of the pairs of box wheels d, whereby the endless chains of the
travelling platform c are actuated.
The axle of the front pair of wheels d is mounted in adjustable boxes
d', which are capable of being moved in slotted bearings by means of
adjusting screws, as shewn at Fig. 1, so as to loosen or tighten the
endless chains c round the wheels d as may be required.
At the front part of the apparatus is an inclined board or shoot / on to
which the manure is drawn from the tail of the dung cart m, to which
the distributing apparatus or manure spreader is attached by chains or
jointed rods m³, m', as shown at Figures 1 and 2. A small steering
wheel 6* is adapted to the front end of the distributing apparatus and
supports that part.
On the top of the manure box is placed a raised platform a* for the
attendant to stand upon. It is surrounded by a railing to prevent him
from being thrown off by accident when the apparatus is jolting over
rough ground. This railing also serves to support a pair of levers and

page_text: rods f¹ and (one on each side), whereby the clutches fand; on the
axle 6' of the running wheels 6 may be worked, when it is desired to
throw the toothed driving wheels in or out of gear with the working
parts.
This manure spreading or distributing apparatus having been
temporarily attached to the manure cart m as already mentioned, and
brought into the field where the manure is to be spread, the workman
operates in the following manner :-He places himself on the raised
platform a* above the distributor, and by means of a fork, rake, or other
suitable instrument he drags the manure in suitable quantities from the
cart on to the inclined shoot 7 of the spreader, and from thence on to the
endless travelling platform c, which carries it forward to the rotary
agitator e. The quantity of manure which is allowed to pass into the
apparatus is regulated by means of an adjustable inclined slide n which
may be raised or lowered as may be required. The lower edge of this
adjustable slide may be provided with projecting teeth or tines, as shown
in the detached view, Fig 4.
Upon the several working parts being thrown into gear the travelling
platform c (on the apparatus being moved forward on the land) will be set
in motion by the running wheels b, b. At the same time the spiked shaft
or agitator e will be rapidly rotated, and will lift the manure from the
travelling platform c, and will toss it up and throw it on to the after or
rear part thereof on which it will be evenly spread. The platform by
continuing to rotate or travel forward will drop the manure out of the
tail of the apparatus and evenly distribute it over the surface of the 2
ground as the apparatus is drawn forward.
The operations of the rotating agitator e or the endless travelling
platform c may be instantaneously stopped by throwing the corre-
sponding clutches for j out of gear by means of the rods or handles
provided for the purpose.

Having now described my Invention of "An Improved Farm-yard
Dung or Manure Spreading Machine and Distributor," and having ex-
plained the manner of carrying the same into effect, I claim as the Inven-
tion secured to me by Letters Patent as aforesaid, the combination with
an ordinary dung cart of a manure distributor or spreader mounted on 3
wheels, and so connected with the cart that the manure from the latter
may be transferred to the distributor, and be thereby evenly spread over

page_text: the ground as the cart with the distributing apparatus connected thereto
is drawn over the ground, as herein set forth.
In witness whereof, I, the said John Pamphilon, the younger, have
hereunto set my hand and seal, the Twenty-seventh day of
December, in the year of our Lord One thousand eight hundred
and seventy-five.
