It is good common practice after use to motor and clean out cement mixers with water, pebbles and /or bricks, to prevent mortar solidifying and ruining the drum, bearings and motor. During this cleaning out operation cement mixers 15 spatter contents out of their open rotating drums which can be a nuisance and a hazard.
PRIOR ART - SHORTCOMINGS & DISASTERS SPATTER NUISANCE & HAZARDS Spatter is a nuisance and a health hazard: a) spatter causes an unsightly mess on the paving, road, and ground near the mixer, 20 b) spatter mess has to be cleaned up at costly labour, time & inconvenience, c) spatter water ruins building sand stored in the open near mixer, d) spatter can soil or damage equipment, vehicles and goods in its wake, e) spatter can soil or damage clothes hair and skin of persons near by, f) spatter can cause temporary / permanent injury to unprotected lungs and eyes, 25 g) spatter inconvenience may postpone cleaning, leading to mixer damage.
Prior Art - No Product Available: At the time of filing, a search carried out on the World Patent Index showed no prior art of Spatter Guards to eliminate the nuisance and hazards of spatter from unguarded Cement Mixers. Nor are Spatter Guards available 30 from manufacturers or building equipment hirers.
2/7 INVENTIVE STEP / OBJECT The inventive step of the present invention is to overcome the above nuisance, hazards and non availability in the present state of the art, by providing Spatter Guards in a variety of models, shapes and sizes, with safe and secure attachment / detachment means to eliminate spatter from Cement Mixers.
SUMMARY OF INVIENTION: A Spatter Guard for eliminating spatter from open revolving drum Cement Mixers comprising means to cover open aperture of mixing drum, means to seal cover to open aperture, means to facilitate assembly of cover to open aperture, and means to quickly securely attach and detach cover to open aperture.
USES:
Eliminates spatter from Cement Mixers becoming a safety hazard and nuisance:- a) causing a mess on the paving, road, and ground near the mixer, b) costly labour, time & inconvenience to clean up spatter mess, c) spatter water ruining building sand stored in the open near mixer, d) spatter can soil or damage equipment, vehicles and goods in its wake, e) spatter can soil or damage clothes hair and skin of persons near by, f) spatter can cause temporary / permanent damage to unprotected lungs and eyes g) spatter inconvenience may postpone cleaning, leading to mixer damage.
MODE OF USE: After loading the cement mixer for the cleaning out operation, (with water, pebbles and /or bricks), the Spatter Guard is lifted by the support handle, offered to the open aperture of the cement mixer drum, and inserted in, where it is held secure by it's retention mechanism, the mixer is then motored till clean, (without the nuisance and hazards of spatter); then stopped, the spatter guard is removed by gripping and pulling the support handle, and the mixer contents emptied safely where desired.
