I, EDWIN DANIEL MEAD, of Phelps, County of Ontario, State of New·
York, U.S.A., Pattern Maker, do hereby declare the nature of this invention to be
as follows:
This invention relates to the hopper mechanism of fertilizer distributing
machines. To the lower part of the inside of the hopper is attached a metal plate
from which extends the fertilizer feed cup provided with a discharge outlet leading
into the discharge spout. Within the lower part of the feed cup is seated a
rotating disc or feed wheel provided on its lower face with gear teeth adapted to
mesh with the pinion of the driving shaft. The feed wheel is formed with a
peripheral recess and the feed cup with a ledge for the reception of a packing ring
between these two parts. The feed wheel is provided with a central opening
registering with an opening formed in an arm which extends across the bottom of
the feed cup and beneath the feed wheel. A scraper wheel and a stirrer are carried
over the feed wheel upon a crank axle so as to revolve excentrically, moved from the
feed wheel, to which the crank axle is fixed. Further the feed wheel has pro-
jections on its upper side which engage in recesses in the scraper wheel and turn
it on its axis. The passage past the discharge spout is regulated by an adjustable
gate and a shield or guard is secured over the scraper wheel.

Improvements in Fertilizer Distributing Machines.
I, EDWIN DANIEL MEAD, of Phelps, County of Ontario, State of New
York, U.S.A., Pattern Maker, 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:-
This invention relates to the hopper or distributing mechanism of fertilizer
distributing machines and in the accompanying drawing Fig. I is a plan view of
the distributer; Fig. 2 a section on line 1-1 of Fig. 1; Fig 3 a detail perspective
view of the various parts; and Fig. 4 a bottom plan view of certain details of
construction.
A is the hopper and B a plate or casting secured to the lower part thereof and
from which extends the feed cup C provided with a discharge outlet D).
E is a rotating disc or feed wheel seated within the lower part of a cup C. It
is provided on its lower face with a series of gear teeth adapted to mesh with a
Price S11

page_text: pinion F said pinion receiving its motion from a shaft G connected with the
driving wheel of the machine.
The feed wheel E is formed on its periphery with an undercut recess or seat a.
Fitting around this seat, and between it and the side face and projecting ledge
of the cup C is a metal, leather, rubber, or other suitable packing ring or band H
which occupies the space formed between the feed wheel and the cup, its ends
projecting through an opening c in the side of the cup, firmly holding it in place
and in its proper relation to the other parts. The principal object is to employ
some material which will prevent leakage of the fertilizer from between the parts.
The feed wheel is provided with a central opening which registers with an
opening formed in a spider arm I which extends across the bottom of cup C
and beneath the feed wheel. The recess d is of two diameters, the lower reduced
portion being formed with two sockets or seats e while the under face of the spider
at one side of said recess is slightly cut away or rounded, as shewn in Fig. 2.
J is a cranked axle, its lower arm K being formed to fit within the opening d
and having studs or lugs f adapted to be seated in the sockets e when the parts are
assembled. Extending from the lower end of the arm is a hook or finger L. That
portion of the arm K opposite the hook is slightly rounded, which permits of the
arm being worked down into the recess and allows the hook or finger to engage
the under face of the spider. No direct pull will separate the parts, but they may
be readily dismantled when it becomes necessary.
It will be noted that this
construction does away with bolts or loose parts which would be liable to come
loose by the continued vibration of the machine.
M is the scraper wheel,, mounted upon the upright stud N of the crank K. It
is formed with a series of openings or slots g in its lower edge, which engage with
teeth formed upon the upper face of the feed wheel C at or near its periphery.
The central portion of the scraper wheel, which receives the stud N is continued
above said stud, and within its upper end is seated a bolt i to which is secured the
stirrer O.
A guard P is secured over the scraper wheel and is of such form as to effectually
prevent the escape of the material around the wheel. It also permits a better or
more advantageous location of the gate Q with relation to the discharge spout, in
that the gate may be placed at a greater distance from the spout and the spout
made larger and left free from all obstruction. The guard is formed with an
opening designed to embrace the upright projection of the scraper wheel before
the stirrer O is secured in place. It is also provided with a downwardly projecting
portion for closing the space between the feed cup and the scraper wheel on the
side opposite the gate. An upturned lip is provided, against which the gate Q
bears. It is of such height that whatever may be the adjustment of the gate the
lip will prevent the material from finding its way around the gate at this point.
To properly hold the guard in place, it is formed with a downwardly projecting
flange m which in turn is provided with two lugs n. A stud o is formed at the
forward right hand side of the guard. The lugs n take into recesses or openings ??
formed in the plate B and the stud o into an opening q. The guard is curved
slightly upward along its upper face near the rear. This curved portion tends to
hold the shaft in its proper position. The outer end of the shaft is provided with
the usual index finger or arm and is journalled in one side of the frame or hopper
to which the index-plate is attached, its inner end resting upon a seat T formed
upon the plate B. The shaft being square and the opening in the gate through
which it passes being of like form the gate must of necessity turn with said shaft.
The lower end of the gate is of such form as to fit down over the feed wheel and
between the cup and scraper wheel, while the upper portion of the gate closes the
space between the side wall of the hopper and the lip of guard P.
-
The gate is shewn closed in dotted lines in Fig. 2 and when in such position
approximately all exit from the hopper is cut off. By raising the gate more or
less, the desired quantity of material may be fed out, but there is no leakage
between any of the parts.

page_text: Under some conditions it may be found desirable to interpose a wedge, as S
between the flange m of guard P and the wall of the hopper to securely hold the
parts while in use, but readily withdrawable when it is desired to take the machine
apart.
In assembling the parts the upright projection of wheel M is passed through the
opening and the stirrer secured in place and need not be removed except for
replacement of broken or worn parts. The shaft and pinion being in place, the
packing H is secured within the cup, after which the feed wheel is put in place.
The arm K of the crank J is then passed through the opening in the feed wheel,
the studs or lugs f entering the recesses e and the huger 1 taking under the spider
frame. This prevents the crank from turning and secures the parts in their proper
position. Next the scraper wheel and guard P are put in place, lugs n entering
the openings p and the stud o the opening the scraper wheel in the meantime
fitting down over the axle N. Finally the wedge S is put in place.
In the operation of the device the gate is adjusted to the proper point and
motion is imparted to the shaft G and is transmitted to the feed wheel through.
the pinion and from the feed wheel to the scraper wheel and the stirrer, the
direction of rotation being indicated in Fig. 1 by arrows.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. In a fertilizer distributer, the combination of the feed cup, a feed wheel
seated within said cup, and a packing interposed between said parts, substantially
as described and shewn.
2. In a fertilizer distributer, the combination of the feed cup provided with an
