We, THOMAS ASHLEY, Junior, of Louth, in the County of Lincoln, Millwright,
and WILLIAM HADDON OWEN, of Louth aforesaid, Solicitor, do hereby declare
the nature of this invention to be as follows:-
The present invention, which relates to drills for sowing corn and seeds, has
for its object to improve the construction, mainly with the view of facilitating
the substitution of one seed barrel for another, when the drill is to be used for
different sized grain or seed.
In carrying out this invention, we employ the usual seed box or hopper,
beneath which rotates the seed barrel. This barrel comprises, as usual, a shaft
extending transversely of the machine, provided at intervals with discs, upon
the faces of which are set up the cups for lifting the seed or grain into the
canisters," as they are generally called. These canisters, according to the
present invention, are so placed forward of the barrel shaft, that the latter can
be lifted out rearwards from its bearings, and another substituted for it, without
the canisters being, as is now necessary, previously removed. The canisters are
hinged to division plates, between which the discs of the barrel rotate, and are
merely turned back clear of the cups, as the barrel is withdrawn.
The hinging of the canisters is, moreover, a means for interrupting the supply
of seed or grain to the drill coulters, as it provides for their removal from the
position to receive the contents of the cups, and permits of the introduction of
slides, which serve the double purpose of keeping back the canisters. and closing
the passages leading to the drill coulters.
The bearings of the barrel shaft are preferably composed of a fixed portion
and a movable portion jointed thereto, the latter being secured, when in position,
by means of a latch or equivalent device.
Intermediate brackets may be introduced to support the seed box, and assist in
sustaining the barrel shaft. In these brackets, bearings of the kind just men-
tioned are fitted, so that the removal of the barrel may be effected with the
minimum of trouble.
The aperture of the spouts leading from the seed box to the trough wherein
the barrel rotates, is preferably placed at such a height that only a given quantity
of seed will be deposited without any further means for regulating the feed being
provided.

page_text: We, THOMAS ASHLEY, Junior, of Louth, in the County of Lincoln, Millwright,
and WILLIAM HADDON OWEN, of Louth aforesaid, Solicitor, do hereby declare
the nature of this invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
The present invention, which relates to drills for sowing corn and seeds, has
for its object to improve the construction thereof, mainly with the view of
facilitating the substitution of one seed-barrel for another, when the drill is to be
used for different sized grain or seed.
In the accompanying drawings we have shown so much of a seed drill as will
serve to illustrate the present improvements.
Fig. 1 is a back view;
Fig. 2 is a transverse section on the line X-X of Fig. 1;
Fig. 3 is a transverse section on the line y-y of Fig. 1;
Figs. 4 are plan and side views of a detachable slide hereafter mentioned.
In carrying out this invention, we employ the usual hopper A, which delivers
seed or grain, by means of shoots a, into compartments b, arranged at intervals
in the box B. In this box rotates the barrel, which comprises, as usual, a shaft C
and discs C*, the latter being set upon the shaft at intervals corresponding with
the compartments b, and being provided with cups c to take up the seed from the
said compartments.
The barrel shaft C is specially mounted, so as to be capable of easy removal,
bearings E being provided at the ends of the box B, and in the intermediate
brackets D, having a fixed part e and a hinged part, which latter opens out
backwards, to open the bearing. It is retained, when in the closed position, by
means of a catch or its equivalent e².
are the canisters into which the seed is thrown by the cups C. These
canisters are mounted forward of the barrel and are hinged to the sides b₁ of the
compartments b, so that the said barrel may be lifted out backwards, and another
substituted, without the removal of the canisters being necessary.
The position of the canister shewn on the left of Fig. 1, is its operating position,
wherein it receives the seed from the cups c, and conducts it, through an aperture
in the side 6 of the compartment b, to the delivery shoot g, which leads to the
tube G.
For convenience of manufacture, the side b₁ of the compartment b and the
shoot g may be one casting, if desired.
The position of the canister to be seen on the right-hand of Fig. 1, is the
inoperative position, the canister being in this case tipped back out of line of the
cups c, so that the seed raised by the cups, falls from thein back again into com-
partment b. In this position the canister may be held by means of a slide H
(shewn detached at Figs. 4), which may be inserted in a guide beneath the
canister, so as to close the aperture in the side of the compartment b.
It will be understood that the canisters are shewn thus, for the sake of illus-
trating the two positions, riz.:-that which the canisters should occupy when
sowing is in progress, and that which they occupy when the supply of seed to the
drill coulters is interrupted.
To permit the removal of the barrel from its box, it will only be necessary to
release the catches 2, open the bearings, and turn back the canisters to the in-
operative position, so as to clear the cups projecting from the barrel discs.

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:-
1. A seed-drill constructed as described, wherein the seed barrel is removably
mounted in rear of the canisters, substantially as and for the purpose above set
forth.
2. In a seed-drill provided with a rotating barrel. and seed cups carried thereby,
the employment of hinged canisters as above described, which canisters are
capable of occupying either an operative or an inoperative position, according
to desire, substantially as set forth.
