IMPROVEMENTS IN SEED SOWING MACHINES
Year: 1884

page_text: THOMAS ROBERT HAY, FISKEN, of East Greenwich in the County of Kent
Engineer, and JAMES EDWARDES WEYMAN, of Guildford in the County of Surrey
Engineer, do hereby declare the nature of their invention for IMPROVEMENTS IN
SEED SOWING MACHINES to be as follows:-
Upon the circumference of the front roller when concave for drilling upon the
ridge or upon a flat one for drilling upon the flat, is cast or fixed discs or projections,
when the roller is drawn or moved forward leaving a small channel or seed furrow
for the seed of a uniform width in a smooth straight line and the ordinary coulter
which gives an uneven and irregular seed channel is dispensed with; For the
purpose of regulating the quantity of seed being sown a disc or drum is placed in
the seed hopper the rim of this disc or drum having recesses or holes made in it,
in the bottom of these recesses or holes are screwed "screw studs" capable of being
screwed in or out, so as to enlarge or decrease the size of the recessor hole these
recesses or holes take up and deliver the seed as the disc or drum revolves so that
the quantity of seed sown is dependent upon the size of the recesses or holes
regulated by the "screw studs."

page_text: We THOMAS ROBERT. HAY FISKEN of 22, Lorne Terrace East Greenwich in the
County of Kent, Engineer, and JAMES EDWARDES WEYMAN of 1, Stoke Terrace
Guildford in the County of Surrey Engineer, do hereby declare the nature of our
invention for IMPROVEMENTS IN SEED SOWING MACHINES, and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement:-
This Invention relates to certain improvements in seed sowing machines; for
making a seed furrow and for regulating the quantity of seed to be sown. These
improvements are illustrated on the accompying drawings. fig; 1. and, 3. which
respectively represent an elevation and plan of a turnip seed sowing machine ;
1. is the front roller, which may be either concave, or parallel. 2 is a disc cast or.
fixed upon the front roller. 1. made.of a V shape so as to leave the bottom of the
seed furrow narrow, 3. is a spout to convey the seed into the furrow; 4. is the seed
hopper. 5 is the seed regulator working in the bottom of the hopper and so fitted
that no seed can pass except that contained within the cavities of the seed
regulator. 6. is the hind roller; 7. is a rope or belt; 8. is a pulley mounted fast
upon the shaft; 9. 9' is a pulley mounted fast upon the shaft of the hind roller, 6.
Motion can be. given to the seed regulator from either the hind or front roller.
fig; 2. is a transverse elevation section through the seed box, seed regulator and
spout, 4 is the hopper 5¹ is the seed regulator, a and. b. are the cavities in the
seed regulator. 8¹ the pulley; 91. the shaft of seed regulator. fig; 4. is a transverse
elevation section and a longitudinal section of the seed regulator showing the holes
or screwed cavities with their respective screwed plugs. c. d. e. f. &c. the plugs have
square studs formed upon them so that a key can take hold of them and srow them
out or in as required. fig; 5. is a transverse section of the front roller 1. (fig; 1.)
showing the projections 10. 11. 12. &c of cone like construction which may be cast
or fixed upon the front roller instead of a disc. It is understood that any number
of discs or any number of series of projections can be cast or fixed upon the roller
according to the number of rows or drills required to be sown at one time. The
action of the Invention is as follows, Seed being put into the hopper (say turnip
seed) when sowing upon the ridge, the front concave roller mounts the ridge and
if the disc is used a small hollow or furrow will be made for the reception of the
seed and if a roller with projections is used dished holes will be made for the
reception of the seed, The seed regulator will receive motion from the onward
movement of the machine and the cavities in the seed regulator will be filled with
seed as they come round and carry the seed round which will fall into the spout
and will be conducted down into the furrow or the dished holes as the case may
be. If too much seed is passing through the regulator then the plugs can be
Bcrewed out so as to contract the cavities and if too little seed is passing through
the regulator then the plugs can be screwed in so as to enlarge the cavities and
thus the quantity of the seed being sown can be regulated,

page_text: Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed, We declare that what
we claim is
First. The use and employment of a disc cast or fixed upon the front roller of
seed sowing machines, substantially as here-in before described with reference to
the accompanying drawings.
Second. The use and employment of knobs or projections cast or fixed upon the
front roller of seed sowing machines substantially as described with reference to
the accompanying drawings.
Third. The use and employment of a seed regulator with cavities in the rim
thereof together with screw plugs which can be screwed out or in so as to
contract or enlarge the cavities, substantially as described with reference to the
accompanying drawings.
