Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
57 words
THE METHOD OF FORMINING FROM LOOSE MATERRIAL COMPRESSED SPECIMEND OF PREDETERMINED HARDNESS, COMPRISING APPLYING TO THE MATERIAL A PROGRESSIVELY INCREASING COMPRESSIVE FORCE AND SIMULTANEOUSLY MEASURING THE REACTION OF SAID MATERIAL INDEPENDENT OF SAID COMPRESSIVE FORCE WHICH IS INDICATIVE OF THE HARDNESS THEREOF, AND CONTINUING THE PROGRESSIVE INCREASE OF SAID COMPRESSIVE FORCE UNTIL THE DESIRED HARDNESS IS INDICATED.
Claim 2
Independent Claim
57 words

Claim 3
Dependent Claim
158 words
APPARATUS FOR FORMING TEST SPECIMENS OF COMPACTED MOLDING MATERIAL, COMPRISING A BASE, A COLUMN AND AN ADJACENT STANDARD RISING FROM SAID BASE, A MOLD TELESCOPICALLY ENGAGING SAID COLUMN, MEANS FOR TEMPORARILY SUPPORTING SAID MOLD ON SAID COLUMN TO EXTEND ABOVE THE UPPER END OF THE LATTER TO RECEIVE AND HOLD THE LOOSE MOLDING MATERIAL, A PLUNGER ENGAGING SAID MOLD ABOVE THE MATERIAL THEREIN AND HAVING AN UPWARDLY EXTENDING THREADED PORTION, A NUT ENGAGING SAID THREADED PORTION, A BIFURCATED LEVER FULCRUMED ON SAID STANDARD AND EMBRACING SAID NUT, BEING ADAPTED TO BEAR DOWNWARD THEREUPON AT DIAMETRICALLY OPPISITE POINTS ADJACENT TO SAID FULCRUM, A WEIGHT ADJUSTABLE ON SAID LEVER, MEAND FOR ROTATING SAID NUT TO MOVE DOWNWARD SAID PLUNGER WITH A FORCE LIMITED BY THE RESISTANCE TO UPWARD MOVEMENT OF SAID WEIGHTED LEVER, AND A GAUGE MOUNTED ON SAID PLUNGER IN OPERATIVE CONTACT WITH THE MATERIAL BEING COMPACTED WITHIN SAID MOLD FOR INDICATING THE HARDNESS THEREOF DURING THE COMPACTING OPERATION.
