Year: 1873

in the County of Suffolk, for the Invention of “IMPROVEMENTS IN
TRAD
MONTAR
PROVISIONAL SPECIFICATION left by the said Graham William
Betham Edwards at the Office of the Commissioners of Patents,
with his Petition, on the 21st January 1873.
I, GRAHAM WILLIAM BETHAM EDWARDS, of Bredfield, in the County
of Suffolk, do hereby declare the nature of the said Invention for
" IMPROVEMENTS IN DRILLS OR MACHINERY FOR DISTRIBUTING ARTIFICIAL MANURE
AND GUANO," to be as follows:-
This Invention relates to improvements in drills or machinery for dis-
tributing artificial or manufactured manure and guano. Hitherto much
difficulty has been experienced in the proper distribution of artificial
manure or guano upon land by means of drills or machinery employed
for this purpose owing to the varied condition of dampness of such

page_text: manure causing the apparatus to clog up and thus provent the proper
and regular delivery of the manure therefrom. Now according to my
improvements I cause artificial manure or guano to be delivered from a
hopper or receptacle mounted upon the drill or machine by means of a
screw or hollow fluted spiral worm arranged in combination therewith.
The manure falls from the hopper between the threads of the screw or
worm which conducts it to an opening on one side of the chamber in which
the screw or worm revolves, where it is delivered in a regular and
uniform manner on to the land, the quantity thus distributed being
regulated by the speed at which the scrow is caused to revolve, the speed
being regulated by the size of the toothed or driving wheel on the screw
axis, or by other suitable mechanical moans.
The surfaces of the screw threads are provented from clogging with
the manure by means of a series of travelling blades or scrapers mounted
upon an endless band and closing the front aperture of the box above
tho screw.
The ends of the blades enter and fit between the threads of
the screw, which acts upon them like a scrics of cog teeth, thus causing
the endless band of scrapers to travel around the rollers upon which the
band is mounted, thereby clearing the surfaces of the screw threads from
any manure that may adhere thereto.
The blades or scrapers may be kept clean by means of a brush, knife,
or other suitable contrivance.
When the nature of the manure requires it a series of reciprocating
bars or blades are so arranged and actuated as to pass into the manure
in the hopper above the screw, and raise or lift the manure and thus
stir and lighten it up before it passes between the threads of the screw or
distributer.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Graham William Botham Edwards in the Great
Soal Patent Office on the 21st July 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GRAHAM
WILLIAM BETHAM EDWARDS, of Bredfiold, in the County of Suffolk,
send greeting.

The manure falls from the hopper between the threads of the screw or
worm which conducts it to an opening on one side of the chamber in
