Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
136 words
A fly press for the production of ceramic tiles or the like, comprising a die for receiving the powder to be compressed, a vertically movable pad integral with a striking mass, a screw for controlling the depressional movements and the lifting movements of the striking mass, a first flywheel solid with said screw and two discs rotatable in the same direction and adapted to be alternatingly brought into contact with diametrically opposite peripheral areas of said flywheel, characterized in that on the screw a second flywheel is idly mounted, means being provided for causing the engagement between the flywheel affixed to the screw and the idle flywheel, said engaging means permitting at least a limited rotational movement of either flywheel relatively to the other flywheel, the first flywheel being lighter in weight than the second flywheel.
Claim 2
Dependent Claim
136 words
A fly press for the production of ceramic tiles or the like, comprising a die for receiving the powder to be compressed, a vertically movable pad integral with a striking mass, a screw for controlling the depressional movements and the lifting movements of the striking mass, a first flywheel solid with said screw and two discs rotatable in the same direction and adapted to be alternatingly brought into contact with diametrically opposite peripheral areas of said flywheel, characterized in that on the screw a second flywheel is idly mounted, means being provided for causing the engagement between the flywheel affixed to the screw and the idle flywheel, said engaging means permitting at least a limited rotational movement of either flywheel relatively to the other flywheel, the first flywheel being lighter in weight than the second flywheel.
Claim 3
Dependent Claim
18 words
A fly press according to claim 1, characterized in that the engagement means consist of a tooth clutch.
Claim 4
Dependent Claim
54 words
A fly press according to claim 2, characterized in that the teeth of said clutch are, respectively, solid with the flywheel affixed to the screw and the idle flywheel and that a free gap exists between the respective teeth so as to permit mutual rotational movements of either flywheel relatively to the other flywheel.
Claim 5
Dependent Claim
54 words
A fly press according to claim 3, characterized in that the teeth solid with the flywheel which is affixed to the screw carry spring biased plungers in registry with their rear front surfaces as referred to the sense of rotation of the flywheel which causes the depressional movement of the striking mass to occur.
Claim 6
Dependent Claim
17 words
A fly press according to claim 1, characterized in that the engagement means consist of a clutch.
Claim 7
Dependent Claim
50 words
A fly press according to claim 5, characterized in that the clutch comprises an inflatable member which can be inflated by compressed air and is affixed to the interior of the flywheel which is solid with the screw, and a second member affixed to the exterior of the idle flywheel.
