The purpose for this application is to introduce a manually
operated device to better assist construction contractors and
tradesmen in the pouring of grout or other relevant materials.
This practice will assure proper compression and avoid dehydration
in cements, thus maintaining the materials true MPA rating.
"Engineers design our buildings in such a way to defeat
nature's destructive elements, and demand greater life expectancy
at a reasonable cost. To achieve this st~n~Ard, most load bearing
walls are erected using masonry units. The cores are then
reinforced with steel rebar and filled solid employing a cementous
grout".
"Masonry contractors have applied various techniques to
transfer this substance from vats by means of pumps and hoses. In
most applications, the traditional methods of using shovels and
pails are still exercised. Both systems have their disadvantages.
Pumps are only cost effective when high lift grouting is
acceptable, while during a low lift procedure, shovels and pails
are time consuming and awkward."
"Nevertheless, engineers are often leery enough about the
contractor's assuredness that all cores are soundly filled and well
compressed from top to bottom. This newly introduced grout
dispenser provides an effective media between costs, proficiency,
and good workmanship".

"This grout dispenser (Fig. l,Z, and 3) is manually operated
when releasing its contents into concrete block cores or similar
applications."
"Most grouting methods require the traditional use of a shovel
to transfer a cementous product from a large cont~in~r into a
portable unit, e.g. a small pail. From here, the material is then
poured into designated cavities. Of course, on certain projects,
a pumping system is used. This method is applied and may prove
beneficial only when high lift grouting is acceptable.
"(High lift means less interruptions in the productivity of a
concrete block wall being erected.)"
"Nowever, engineers are sceptical that a very high cavity may
be obstructed by falling debris during construction, thus resulting
in poorly filled voids. For this reason, LOW lift is recommended.
Pumping devices are then denigrated due to their mass capability
for delivering cement in overly stated volumes. The contractor is
then compelled to subdue the quantity of material being poured, and
will use the traditional shovel and pail method." In all
applications, cementous grout must be applied 'soon after being
mixed."
"This unit will ensure that the allocated time of placement
meets the engineer's specifications."

"In most common practices, the substance is poured into a flat
bin, then transported to its final destination where the material
is manually handled with shovels. The grout dispenser as shown by
Fig. 1,2, and 3, overcomes this process. e.g. Instead of filling
a flat bin, the dispenser is filled. In both cases, each contAiner
would be transported. Nowever, crewmen must help themselves to the
flat bin with shovels and pails rather than simply placing their
pails under the shoot (1) of the dispenser and pull the handle (2).
When applicable, even the pail is not necessary when the unit is
placed directly above the area being grouted."
"The trap door (3) is efficiently maneuverable, and slides
across on two rails (4) to readily cut the flow of material without
obstruction. The large triangular shaped handle (2) implements a
well balanced force to facilitate the trap door's (3) operations.
The dispenser itself is heavily braced by top (5) and bottom
collars (6) to prevent buckling. As a safety measure, the bottom
collar (6) has been angled in all directions to prevent accidental
injuries. (as shown in FIG. 1, detail (7) ).
"FIG.1 also provides reinforcement details in the placement of
gussets (8) where required. FIG 3 displays a top view of the
hopper, and is capable of holding approximately 20 cubic feet of
material".

"On most construction sites, the traditional flat containers
are too large to be stationed in every area within the structure
being built. This is where wheelbarrows take over. Again, the
slow painstaking manual transfer of material is applied. The
dispenser has been designed to pass through any hallway or st~n~rd
28 inch door frame when the fork truck transporting rails (9) are
removed. (FIG. 4, and 5). The connecting plates (10), and bolts
(11) make this very efficient."
(The unit itself is then placed on a portable caddy with wheels.
(NOT SHOWN AS PART OF THIS APPLICATION).
"F~g. 1, and 2 demonstrates the two methods of transportation.
One being with the fork truck transporting rails, (9) and the
secondary use of a crane hook-up system by means of lifting eyes
(lZ).
"This (bulk material dispenser) is constructed of heavy gauge
steel and weighs approximately 500 lbs. with a total height of 56
inches by 40 inches (side view), and 40 inches (front and back
view). Front and back view is reduced to Z8 inches when the
transporting rails are removed. The finish is well painted with a
rust-proofing material, and is easily cleaned with water".
"Other applications are evident, and are not limited to
concrete block core filling. e.g. filling sona tubes, footings or
small foundations where large trucks cannot pass. This unit may
also be used to dispense soil or other materials into small bags
when stationed on a pedestal".
The timesaver 2000 modernizes low lift grouting and other
applications without ~he use of a shovel!
