Description

TIMESAVER Z000 June 19, 1997 (Bulk Material Dispenser) Cornwall, Ontario In reference to:

JEAN-MARC ALBANIE RIVETTE (AND) ROBERT ERNEST PATENAUDE

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".

June 19, 1997 "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."

(BULK ~ATERIAL DISPENSER) SPECIFICATIONS
June 19, 1997 "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".

June 19, 1997 "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!
