Pavement laying apparatus

Claim 1

A METHOD OF LAYING PAVING UNITS ON THE GROUND IN A PATTERN IN A CEMENT MOTAR BED WITH THE AID OF A LEVEL ROD AND A PATTERNED GRATING RESTING UPON A PAIR OF UPON RAILS WHICH COMPRISES THE STEPS OF POSITIONING AND LEVELING SAID GUIDE RAILS UPON SAID GROUND A DISTANCE APART FOR SUPPORTING SAID LEVEL ROD AND SAID PATTERNED GRATING BETWEEN THEM, DISPOSITING SAID CEMENT MORTAR BED UPON SAID GROUND BETWEEN SAID RAILS, DETERMINING THE UPPER SURFACE LIMIT OF SAID SEMENT MORTOR BED BY RESTING SAID LEVEL ROD UPON AND BETWEEN SAID RAILS AND MOVINGL IT ACROSS THE SPACE BETWEEN THEM FOR STRIKING OFF THE UPPER SURFACE OF SAID CEMENT MORTAR BED TO SAID UPPER SURFACE LIMIT, POSITIONING SAID GRATING UPON AND BETWEEN SAID GUIDE RAILS TO DISPOSE IT AT A PREDETERMINED HEIGHT AND HORIZONTAL POSITIN FOR GUIDING INSERTION OF SAID PAVING UNITS INTO SAID CEMENT MORTAR, THE LOWER SURFACE OF SAID GRATING BEING DISPOSED A SUBSTANTIAL DISTANCE ABOUT SAID DETERMINED UPPER SURFACE LIMIT OF SAID CEMENT MORTAR TO PERMIT SAID CEMENT MORTAR TO FREELY RISE TOWARD SAID GRATING AND AROUND SAID PAVING UNITS WHEN THEY ARE INSERTED THROUGH SAID GRATING INTO SAID CEMENT MORTAR, INSERTING SAID PAVING UNITS THROUGH SAID GRATING INTO SAID CEMENT MORTAR BED, AND ALIGNING THE TOP SURFACES OF SAID PAVING UNITS WITH THE UPPER SURFACE OF SAID PATTERNED GRATING WHEREBY THEY ARE DISPOSED IN A FLAT SURFACE AND IMMERSED TO A PREDETERMINED DEPTH IN SAID CEMENT MORTAR TO PROVIDE A SUBSTANTIAL UNIFORM JOINT BETWEEN SAID PAVING UNITS AND SAID CEMENT MORTAR.

Claim 2

A METHOD OF LAYING PAVING UNITS ON THE GROUND IN A PATTERN IN A CEMENT MOTAR BED WITH THE AID OF A LEVEL ROD AND A PATTERNED GRATING RESTING UPON A PAIR OF UPON RAILS WHICH COMPRISES THE STEPS OF POSITIONING AND LEVELING SAID GUIDE RAILS UPON SAID GROUND A DISTANCE APART FOR SUPPORTING SAID LEVEL ROD AND SAID PATTERNED GRATING BETWEEN THEM, DISPOSITING SAID CEMENT MORTAR BED UPON SAID GROUND BETWEEN SAID RAILS, DETERMINING THE UPPER SURFACE LIMIT OF SAID SEMENT MORTOR BED BY RESTING SAID LEVEL ROD UPON AND BETWEEN SAID RAILS AND MOVINGL IT ACROSS THE SPACE BETWEEN THEM FOR STRIKING OFF THE UPPER SURFACE OF SAID CEMENT MORTAR BED TO SAID UPPER SURFACE LIMIT, POSITIONING SAID GRATING UPON AND BETWEEN SAID GUIDE RAILS TO DISPOSE IT AT A PREDETERMINED HEIGHT AND HORIZONTAL POSITIN FOR GUIDING INSERTION OF SAID PAVING UNITS INTO SAID CEMENT MORTAR, THE LOWER SURFACE OF SAID GRATING BEING DISPOSED A SUBSTANTIAL DISTANCE ABOUT SAID DETERMINED UPPER SURFACE LIMIT OF SAID CEMENT MORTAR TO PERMIT SAID CEMENT MORTAR TO FREELY RISE TOWARD SAID GRATING AND AROUND SAID PAVING UNITS WHEN THEY ARE INSERTED THROUGH SAID GRATING INTO SAID CEMENT MORTAR, INSERTING SAID PAVING UNITS THROUGH SAID GRATING INTO SAID CEMENT MORTAR BED, AND ALIGNING THE TOP SURFACES OF SAID PAVING UNITS WITH THE UPPER SURFACE OF SAID PATTERNED GRATING WHEREBY THEY ARE DISPOSED IN A FLAT SURFACE AND IMMERSED TO A PREDETERMINED DEPTH IN SAID CEMENT MORTAR TO PROVIDE A SUBSTANTIAL UNIFORM JOINT BETWEEN SAID PAVING UNITS AND SAID CEMENT MORTAR.
