Dispensing device arranged to reduce the risk of strain and injury during use

A method of dispensing flowable material to low areas including the steps of:

• a. providing a device including:
• a hollow cylinder having a front end wall and a rear end wall spaced apart in the axial direction of the cylinder;
• at least one piston displaceably mounted within the cylinder and adapted to reciprocate between a forward ejecting direction and a return direction;
• at least one driven rod connected to said piston, said driven rod extending through the front end wall of said cylinder;
• a trigger mechanism including a handle and an actuatable trigger which, upon actuation, supplies a pressure medium through a conduit to the rear portion of the cylinder for slidably displacing the piston in the forward ejecting direction for dispensing flowable material;
• and
• an elongated extension piece having distal and proximal ends, the extension piece being secured at its distal end to said hollow cylinder, said extension piece extending upwardly above the hollow cylinder to said proximal end, said trigger mechanism be secured to said extension piece adjacent said proximal end at a location spaced upwardly from the hollow cylinder when the device is being used to dispense the flowable material;
• b. engaging said device by said handle with the hollow cylinder extending below said handle in a position for dispensing the flowable material;
• and
• c. actuating said trigger mechanism for dispensing said flowable material.

A method of converting a device including a trigger mechanism spaced vertically upward from a hollow cylinder of the device to dispense flowable material in low areas to a device wherein the vertical spacing between the trigger mechanism and the hollow cylinder is eliminated, said method including the steps of:

• a. providing a device including:
• a hollow cylinder having a front end wall and a rear end wall spaced apart in the axial direction of the cylinder;
• at least one piston displaceably mounted within the cylinder and adapted to reciprocate between a forward ejecting direction and a return direction;
• at least one driven rod connected to said piston, said driven rod extending through the front end wall of said cylinder;
• a trigger mechanism including a handle and an actuatable trigger which, upon actuation, supplies a pressure medium through a conduit to the rear portion of the cylinder for slidably displacing the piston in the forward ejecting direction for dispensing the flowable material;
• and
• an elongated extension piece having distal and proximal ends, the extension piece being secured at its distal end to said hollow cylinder, said extension piece extending upwardly above the hollow cylinder to said proximal end, said trigger mechanism be secured to said extension piece adjacent said proximal end at a location spaced upwardly from the hollow cylinder when the device is being used to dispense the flowable material in low areas;
• b. removing said trigger mechanism from said elongated extension piece;
• c. removing the elongated extension from said hollow cylinder by separating the distal end of the extension means from said hollow cylinder;
• and
• d. attaching said trigger mechanism to the location of the hollow cylinder at which the distal end of said extension piece previously was secured.

A method of converting a device including a trigger mechanism closely positioned to, and attached to a hollow cylinder for dispensing flowable material from the device by actuation of the trigger mechanism, to a device wherein the trigger mechanism is spaced vertically upward from the hollow cylinder of the device to dispense the flowable material in low areas, said method including the steps of:

• a. providing a device including:
• a hollow cylinder having a front end wall and a rear end wall spaced apart in the axial direction of the cylinder;
• at least one piston displaceably mounted within the cylinder and adapted to reciprocate between a forward ejecting direction and a return direction;
• at least one driven rod connected to said piston, said driven rod extending through the front end wall of said cylinder;
• a trigger mechanism including a handle and an actuatable trigger which, upon actuation, supplies a pressure medium through a conduit to the rear portion of the cylinder for slidably displacing the piston in the forward ejecting direction for dispensing the flowable material, said trigger mechanism being closely positioned to and attached to said hollow cylinder;
• b. disconnecting the trigger mechanism from its attachment to said hollow cylinder;
• c. providing an elongated extension piece having distal and proximal ends;
• d. attaching the extension piece at its distal end to said hollow cylinder, said extension piece extending upwardly above the hollow cylinder to said proximal end;
• and
• e. attaching said trigger mechanism to said extension piece adjacent said proximal end at a location spaced upwardly from the hollow cylinder to adapt the device for dispensing the flowable material in low areas.

A convertible device for dispensing flowable material to, said device comprising:

• a. a hollow cylinder having a front end wall and a rear end wall spaced apart in the axial direction of the cylinder;
• b. at least one piston displaceably mounted within the cylinder and adapted to reciprocate between a forward ejecting direction and a return direction;
• c. at least one driven rod connected to said piston, said driven rod extending through the front end wall of said cylinder;
• d. a trigger mechanism including a handle and an actuatable trigger which, upon actuation, supplies a pressure medium through a conduit to the rear portion of the cylinder for slidably displacing the piston in the forward ejecting direction for dispensing flowable material;
• and,
• e. an elongated extension piece having distal and proximal ends, the extension piece being removably securable at its distal end to said hollow cylinder, said trigger mechanism being removably securable to said extension piece adjacent said proximal end and also being removably securable to the hollow cylinder in place of said distal end of said extension piece, whereby said trigger mechanism can be removably secured to said hollow cylinder in place of the distal end of the elongated extension piece or alternatively can be removably secured adjacent the proximal end of said extension piece with the distal end of said extension piece being removably secured to said hollow cylinder.
