COMPLETE SPECIFICATION.
Improvements in Seeding Machines.
LYMAN MELVIN JONES, Manufacturer WILLIAM F JOHNSTON, Manufacturer
both of the City of Toronto, in the County of York, Province of Ontario, Canada 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:-
Our invention relates to improvements in seeding machines and more particularly
to what is known as the shoe drill and the object of our invention is to provide
a simple, light, easily handled and durable conveyer to connect the grain distributor
or feed run with the shoe or runner and thereby very materially increase the
lasting qualities of this portion of the machine and it consists essentially of a
metallic tubular conveyer suitably connected to the feed run and a corresponding
tubular conveyer peculiarly connected to the shoe and within which the former
tubular conveyer is designed to have a telescopic movement as and for the purpose
hereinafter more particularly explained.
Fig. 1, is a perspective view of the shoe and the accompanying parts of which my
invention relates.
Fig. 2, is an enlarged sectional perspective view showing the arrangement of the
telescopic tubular conveyers and their peculiar mode of connection to the shoe.
Fig. 3, is a perspective view of the lower tubular conveyer and the shoe to which' it
is connected.
Fig. 4, is a perspective detail of the lower portion of the tubular conveyer connected
to the shoe showing the thimble and hook.
In the drawings like letters of reference indicate corresponding parts in each
figure.
A is one of the feed runs, which is connected to the hopper B, portion only of
which is shown, and may be of any usual construction now commonly in use.
C is a shoe, which is connected by the drag-bars D D to brackets E E on the
transverse bar F at the front of the machine. G is a rod, which is pivotally con-
nected between the drag bars at the front of the shoe and extends up through a
bracket H secured to the transverse rod I. 9 is a pin, which extends through
the bottom end of the rod G. g is a pin, which extends through the top end of
of such rod above the bracket H. J is a spiral pressure spring extending between
the bracket H and the ping and designed to exert a downward pressure upon the
drag bars and shoe. So far the parts described are of the usual construction in
machines of this class.
K is the upper tubular conveyer, which has an enlarged upper end k provided
with slots k', which are fitted over the pins a extending from each side of the
feed-run. By means of these pins' the upper tubular conveyer K is maintained in
position and allowed a swinging movement. The upper tubular conveyer K is
made preferably of parallel metal tube of iron galvanized' to preserve it from
rusting!
The shoe or runner C is a divided shoe, which converges to a knife edge' at
the front and is formed of the two sides C''C' which are spread at the rear and
have fitted between them the conveying socket L, which is suitably secured in
position and has a central opening for the passage of the seed to between the
sides of the shoe. The socket L is provided with a rearward U-shaped extension' L'.
K' is a metal tubular conveyer parallel throughout and preferably formed of iron'

page_text: The
galvanized. The conveyer K fits and is designed to have telescopic movement within
the conveyer K. M is a thimble, which is provided with a central flange m.
lower end of the tubular conveyer K¹ extends down outside the thimble and abuts
the top of the flange m. The bottom of the flange is designed to abut the top of the
conveying socket Land the bottom of the thimble M abuts a shoulder in the con-
veying socket, so as to present no shoulder for the lodging of the seed. is a hook,
which is arranged preferably to be at the rear side of the thimble and fits within the
hollow U-shaped extension L'.
N is a split pin, which is inserted through holes in the side of the U-shaped
extension L' and passes within the hook m and thereby serves to detachably connect
the tubular conveyor K¹ with the shoe or more properly the conveying socket attached
to 'the shoe.
We do not describe in this specification the lever and means whereby all shoes of
the machine are raised simultaneously as such means form no part of our invention
but we may merely state that each shoe is adjusted in relation to the feed-run either
to apply varying degrees of pressure or to elevate the shoes for transportation and the
tubular conveyers are held together during such movements by reason of their
telescopic connection.
Our tubular conveyers are so arranged that the end of the tubular conveyer K
extends sufficiently far into the tubular conveyer K', so as to absolutely prevent them
being disconnected by any adjustment of the shoes in relation to the feed-run caused
by such shoes travelling over the unevenness of the ground surface. In order to
attach the tubular conveyers they must first be telescopically connected and it is then
merely necessary to insert the thimble of the lower tubular conveyer into the socket L
and then insert the split pin over the hook. The top of the upper conveyer may then
be.connected to the pins attached to or forming part of the feed-run.
Should the lower tubular conveyer become broken or injured and it be desired
to detach the lower tubular conveyer K this may be readily and quickly done by
simply withdrawing the split pin instead of as at present required by detaching the
drag bars and the pressure rod and spring.
Although I describe in this specification the tubular conveyers as connected to a
shoe such as described it will of course be understood that they might be used
with any suitable runner or other device designed to open the ground and deposit
the seed.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a seeling machine a telescopic seed conveyer and detachable connections at
each end in proximity to the seed inlet and outlet as and for the purpose specified.
2. In a seeding machine in combination the feed-run, the shoe, the opening between
the sides, the lower tubular conveyer detachably connected to the shoe and lealing to
the opening between the sides and the upper tubular conveyer detachably connected
to the feed run, extending into the lower tubular conveyer, and designed to have a
telescopic movement therein as and for the purpose specified.
3. In a seeding machine a shoe or runner suitably supported and tubular conveyer
extending upwardly therefroms and detachable means for connecting such conveyer to
the shoe as and for the purpose specified.
4. In a seeding machine a shoe or runner suitably supported, a conveyer socket
secured between the sides of the shoe at the rear end thereof, a tubular conveyer
extending upwardly from such socket and detachable means for connecting the tubular
conveyer to the socket as and for the purpose specified.
5. In a seeding machine a shoe or runner suitably supported, a conveyer socket
secured between the sides of the shoe at the rear end thereof, a tubular conveyer
extending upwardly from such socket and a hook at the bottom rear end of the
tubular conveyer and a suitable pin or projection with which it is designed to
engage as and for the purpose specified.

page_text: 6. In a seeding machine a shoe or runner suitably supported, a conveyer socket
secured between the sides of the shoe at the rear end thereof, a U-shaped extension
to such socket and pin extending through such U-shaped extension and the tubular
conveyer having a hook formed at its rear bottom end, and the co-acting pin
extending through the U-shaped rearward extension as and for the purpose specified.
7. In a seeding machine a shoe or runner suitably supported, a conveyer socket
secured between the sides of the shoe at the rear end thereof, a U-shaped extension
to such socket and pin extending through such U-shaped extension, the tubular
conveyer, the thimble forming the extension thereof provided with an exterior inter-
mediate flange and having the end abutting an annular shoulder in the top of the
socket against which the end of the thimble abutts and a hook on the thimble designed
to grasp the pin extending through the U-shaped extension as and for the purpose
specified.
8. In a seeding machine, in combination the feed-run, the upper rigid tubular-
conveyer detachably connected thereto, the shoe suitably supported and means for
applying pressure thereto, and a lower rigid parallel tubular conveyer detachably
connected to the shoe and within which the upper rigid tubular conveyer is designed.
to have telescopic movement as and for the purpose specified.
9. In a seeding machine, in combination the feed-run, the upper rigid tubular
