APPARATUS FOR DISPENSING GRAVEL

APPAREIL DE DISTRIBUTION DE GRAVIER

English Abstract

Gravel is fed into and spread onto the floor of a newly constructed basement by a hanging frame which attaches to a window sill and supports a hydraulically driven conveyor belt with a feed spout at a feed end of the conveyor belt and a guidance belt mounted on top of the conveyor belt. The hanging frame converges to a front post which pivotally supports a frame of the conveyor belt for movement side to side about an upright axis through the feed spout and carries an adjustable brace which raises and lowers the conveyor. A feed chute is located outside the window. The conveyor includes a guide conveyor on top and is driven by a power source and pump located outside the building.

French Abstract

Du gravier est versé et étalé sur le plancher d'une fondation neuve par un bâti suspendu, qui est fixé à un seuil de fenêtre et supporte une courroie de convoyeur à commande hydraulique, avec un bec d'alimentation et un côté alimentation de la courroie de convoyeur, ainsi qu'une courroie de guidage monté par-dessus la courroie de convoyeur pour assurer un mouvement latéral par rapport à un axe vertical à travers le bec d'alimentation; il porte un tirant réglable qui élève ou abaisse le convoyeur. Une goulotte d'alimentation est située à l'extérieur de la fenêtre. Le convoyeur comprend un convoyeur guide au sommet et est entraîné par une source de courant et une pompe située hors de l'immeuble.

DETAILED DESCRIPTION
The apparatus for gravel and/or concrete in a basement includes a
continuous conveyor belt 10 wrapped around two spaced rollers 11 and 12
carried at
opposite ends of a frame 14 so as to define an upper run 15 of the belt for
conveying
the material.
One of the rollers 11 and 12 is driven by a hydraulic motor 13 from a
power source an pump assembly 18 through supply lines 17. The separate unit 18
is arranged to be transportable and located outside a window opening 20 of the
basement to be supplied.
A feed spout 17 is located at a feed end of the conveyor belt 10 for
guiding the particulate material onto the conveyor belt. The feed spout is
arranged
to be filled with the material from a chute 21 extending through the opening
20 with
an upper mouth 22 for receiving the material from a discharge chute of a
delivery
truck or the like.
A guidance belt 24 is mounted on top of the conveyor belt and is
wrapped around two spaced rollers 25, 26 so as to define a lower run of the

CA 02631189 2008-05-05
guidance belt for guiding the material as it travels along the conveyor belt.
The
length of the guidance belt is shorter than the main belt so that it starts
after the
spout 16 and ends before the end of the main belt. Thus it acts to guide and
accelerate the material on the main belt so that it formed into a thin stream
fed
5 forwardly and ejected from the end of the main belt to be thrown thereby to
required
locations in the basement area. The distance of throw is controlled by the
speed of
the belt and the height of the discharge end of the belt.
A support frame supports the rollers of the conveyor belt and provides
a support for the upper run and carries the guidance beit on top of the
conveyor belt.
The support frame comprises two parallel bars 30 and 31 forming a top frame
together with two bottom bars 32 and 33 forming a bottom frame with cross bars
35
to support the upper run and upstanding bars 36 connecting the top and bottom
frames. The rollers 11 and 12 are located within the frame so formed. The
guidance conveyor 24 is located on top of the bars 30 and 31 and is carried
thereby.
The support frame is carried by mounting frame defined by a pair of
hanging arms 40 and 41 with upper hook portions 42 and 43 shaped and arranged
to engage over the sill 44 of the basement window opening 20 at spaced
positions
across the window such that the arms hang down from the sill inside the
basement
to a position spaced from the ground 46. A mounting portion 47 extends
forwardly
from the hanging arms across the ground and converges to a post 48 forward
end.
The mounting portion 47 is generally triangular converging from the
pair of hanging arms to the front post 48 and includes two triangular frame
pieces 49

CA 02631189 2008-05-05
6
and 50 with one above the other and each including a cross rail 51, 52
connecting
the hanging arms and two converging rails 53, 54 and 55, 56 extending
forwardly
and inwardly from the cross rail to an apex at the front post. A rail 57 of
the bottom
frame 50 extends from the rail 52 through the apex to the post 48.
A pivot mount is defined n the post 48 for pivotal movement about a
generally upright axis and includes a bottom pivot 58 and a top pivot 59
positioned
just in front of the post.
The pivot mount has couplings 60 and 61 thereon for attachment to the
support frame at the feed end of the conveyor to carry the support frame and
to
provide pivotal movement of the support frame about the upright axis 62 at the
feed
end. The pivot mount is attached to the feed end of the support frame to
provide
pivotal movement of the support frame about a generally horizontal axis 63
transverse to the conveyor at the feed end so as to allow upward and downward
movement of the discharge end of the conveyor. The pivot mount is carried on
an
upper pivot of the post and comprises a horizontal arm and a pair of
upstanding
supports where each upstanding support defines one of a pair of trunnions each
receiving a pin 66 of the frame.
A brace 67 is attached to the coupling 61 of the mounting portion for
pivotal movement about the upright axis 62 and extending upwardly and
outwardly
along the support frame so as to engage and support the support frame by
another
support defining trunnions 68 and 69 at a position thereon spaced outwardly of
the

CA 02631189 2008-05-05
7
pivot mount. The brace is adjustable in length at adjustment 70 to adjust the
height
of the discharge end of the conveyor.
Since various modifications can be made in my invention as herein
above described, and many apparently widely different embodiments of same made
within the spirit and scope of the claims without department from such spiirit
and
scope, it is intended that all matter contained in the accompanying
specification shall
be interpreted as illustrative only and not in a limiting sense.
