Multi-purpose scraping apparatus

A multi-purpose scraping apparatus as shown in claim, 1, the handle further comprising:

• a handle body, a tapered torso at its proximal end, a handle lip and a handle face;
• the handle body having a plurality of longitudinal grooves defining ridges, the tapered torso interposed between the handle body and the handle lip;
• the handle lip having a plurality of lip grooves defining lip ridges, the handle lip being interposed between the tapered torso and the handle face;
• the handle face being substantially perpendicular to the handle lip and having a shank aperture in its center;
• the shank aperture having grooves disposed in its interior being constructed and arranged to facilitate receipt of the shank;
• the shank further comprising a handle end portion, a shank central portion and a blade end portion;
• the handle end portion having shank ridges;
• and
• the shank ridges being received in the shank aperture grooves of the handle.

A multi-purpose scraping apparatus comprising, in combination:

• a handle, a shank, and a blade receiving assembly;
• the handle being constructed and arranged to facilitate gripping thereof by a human hand, and having means for securing the shank to the handle;
• the shank being connected to the handle at one end and the blade receiving assembly at its opposite end, thereby maintaining the handle and the blade receiving assembly in spaced apart relation;
• the blade receiving assembly comprising a back plate, a stop plate, a spring plate, a spring tongue and means for securing the spring plate to the back plate;
• the back plate being connected to the shank;
• the stop plate being secured to the back plate;
• the spring plate being secured to the stop plate;
• the spring tongue extending from the spring plate and providing means for moving the blade receiving assembly from a gripping position to a releasing position;
• the back plate and the spring plate being constructed and arranged to cooperatively engage a blade to be used with the scraping apparatus and to bias the blade receiving assembly in the gripping position;
• whereby the spring tongue is movable to effect movement of the blade receiving assembly from the gripping position to the releasing position;
• the back plate having an outer face and an inner face;
• the outer face having a proximal flat portion located proximate to the shank, a ridge and a distal flat portion, the ridge having at least one lateral indentation and being elevated in relation to the proximal flat portion;
• the inner face having a proximal flat portion located proximate to the shank, a depression and a distal flat portion, the depression being depressed in relation to the proximal flat portion;
• the back plate being constructed and arranged to be of substantially uniform thickness;
• the spring plate having an outer face and an inner face;
• the outer face having a first proximal flat portion and a second proximal flat portion located proximate to the shank, a ridge and a distal flat portion, the ridge having at least one lateral indentation and being elevated in relation to the proximal flat portions;
• the inner face having a first proximal flat portion and a second proximal flat portion located proximate to the shank, a depression and a distal flat portion, the depression being depressed in relation to the proximal flat portions;
• the spring plate being constructed and arranged to be of substantially uniform thickness;
• the means for securing the spring plate to the back plate defining a pivoting axis being substantially perpendicular to the shank;
• and
• the distal flat portion of the inner face of the back plate being proximate to the distal flat portion of the inner face of the spring plate when the blade receiving assembly is in the gripping position, and the distal flat portion of the inner face of the back plate being moveable away from the distal flat portion of the inner face of the spring plate by depressing the spring tongue and moving the blade receiving assembly into the releasing position.
