hopper when it is inserted to operative po-
sition through one of the door openings 2,
a pair of plates 13 are secured to the sides
of the hopper and project beyond the back
5 thereof, the plates 13 being provided with
lower notches or recesses 14 engageable over
the sills 4 of the door openings 2. A cross
rod 15 is engaged through the plates 13
above the notches 14, and has its ends pro-
.0 jecting to provide stops 16 projecting from
the plates 13 and adapted to contact with the
inner sides of the jambs 5 of the door open-
ings.
When the silo is filled with the ensilage, it
15 being understood that the doors-6 are closed,
the hopper 11 is disposed.upon the ensilage
so as to be stored within the silo for ready
use whenever desired. When it is desired to
discharge the ensilage, the doors 6 above the
20 level of the ensilage are opened, and the
hopper 11 is inserted outwardly, with its
spout foremost, through that opening 2 at
the level of the ensilage, the notches 14 of
the plates 13 being engaged over the sill 4
25 of the said door opening 2, and the hopper
11 then being swung upon the sill 4 to oper-
ative position, as seen in Fig. 1, which will
cause the spout 12 to automatically swing
through the proper inlet opening 9 of the
30 chute 7, and to thereby swing the respective
valve or door 10 open. The stops 16 of the
hopper in contacting with the inner sides
of the jambs 5 will hold the hopper against
excessive outward movement, so that the
35 hopper will be properly and firmly held in
place with the spout 12 thereof projecting
into the chute 7. The ensilage may then be
shoveled or pitched into the hopper 11, from
which it will be discharged through the
40 spout 12 into the chute 7, and down the chute
to the ground. Then, after the ensilage has
been sufficiently removed to enable the next
succeeding door 6 to be opened, this is done,
and the hopper 11 is swung back into the
45 silo, and then inserted through the next suc-
ceeding lower door opening 2 in the same
manner as above described. Thus, as the en-
rilage is removed from the silo, the hopper
may be adjusted downwardly accordingly,
50 without great trouble.
Attention is directed to the fact that with
the present contrivance, the chute is dis-
posed at one side of the door openings 2 of
the silo, which will not in any manner in-
55 terfere with the- admission of light and air
into the silo through the door openings 2
when the doors are opened, and furthermore
the operator may readily ascend and descend
the silo along the usual ladder provided on
60 the doors 6.
The present device is most satisfactory and
convenient in practice, and is capable of in-
expensive manufacture and application. The
other advantages and features of the pres-
65 ent structure will be obvious to those famil-iar in the art, without further comment be-
ing deemed necessary.
Having thus described the invention, what
is claimed as new is
1. The combination with a silo having a 70
vertical series of openings, of a chute car-
ried by the silo adjacent to -said openings
and having a series of side inlets, and means
adjustable vertically to the various silo open-
ings for catching ensilage and for directing 75
it through one of said inlets into the chute.
2. The combination with a silo having a
vertical series of openings, of a chute carried
by the silo adjacent to said openings and
having a series of side inlets, and a verti- 80
cally adjustable hopper adapted to be car-
ried by the silo adjacent the said openings
and having a spout insertible through the
said inlets of the chute.
. 3. The combination with a silo having a 85
vertical series of openings, of a chute carried
by the silo at one side of the said openings,
the chute having inlet openings in that side
adjacent the said openings of the silo, flap
valves hinged to the chute to normally close so
the inlet openings thereof, and a hopper ar-
ranged to be carried by the silo adjacent the
openings thereof and having an obliquely
projecting spout insertible through the said
inlet openings of the chute. 95
4. The combination with a silo having a
vertical series of openings, of a chute carried
by the silo adjacent to said openings and
having side inlets, and a hopper insertible
from within the silo outwardly through the ioc
said openings, the hopper having a spout
insertible through one inlet of the chute
when the hopper is inserted outwardly
through one of the openings of the silo, and
having means for supporting it in place 105
when inserted outwardly through one of the
said openings.
5. The combination with a silo having a
vertical series of openings, of a chute car-
ried by the silo adjacent to said openings, 110
and a hopper insertible outwardly through
the said openings from within the silo and
having a spout coperable with the chute
when the hopper is inserted outwardly
through one of the said openings, the hopper 11
having means engageable upon the sill of the
opening through which it is inserted, and.
having stops engageable with the interior of
the silo for holding the hopper against ex-
cessive outward movement. 120
6. The combination with a silo having a
vertical series of openings, of a chute carried
by the silo at one side of the said openings,
a hopper insertible outwardly through the
said openings from within the silo and hav- 125
ing a spout coperable with the said chute
when the hopper is inserted outwardly
through one of the said openings, plates at-
tached to the hopper and having notches
engageable over the sill of the opening 1
