Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
127 words
A leveling device comprising: a holder having a pocket for a level tube and having an upright mounting plate spaced above the pocket and spaced forwardly of the rear of the pocket, guide means at the front of the holder adjacent the bottom of the mounting plate for properly positioning the holder on an object to be leveled, and securing means for holding said mounting plate on said object after the holder has been positioned thereon, said holder having a reduced cross-sectional area above said guide means whereby the pocket may be readily severed from the mounting plate by the force applied by pressing the object rearward toward the mounting plate while the back of the holder at the rear of the pocket bears against a wall.
Claim 2
Dependent Claim
127 words
A leveling device comprising: a holder having a pocket for a level tube and having an upright mounting plate spaced above the pocket and spaced forwardly of the rear of the pocket, guide means at the front of the holder adjacent the bottom of the mounting plate for properly positioning the holder on an object to be leveled, and securing means for holding said mounting plate on said object after the holder has been positioned thereon, said holder having a reduced cross-sectional area above said guide means whereby the pocket may be readily severed from the mounting plate by the force applied by pressing the object rearward toward the mounting plate while the back of the holder at the rear of the pocket bears against a wall.
Claim 3
Dependent Claim
45 words
A leveling device according to claim 1 in which said guide means comprises a pair of spaced forwardly projecting prongs arranged to have a line of contact with the underside of said object which is level when a level tube in said pocket is level.
Claim 4
Dependent Claim
31 words
A leveling device according to claim 2 in which said prongs are adapted to readily break free of said holder when said object is pressed rearwardly as described in claim 1.
Claim 5
Dependent Claim
23 words
A leveling device according to claim 1 in which said reduced cross-sectional area is located between said guide means and said mounting plate.
Claim 6
Dependent Claim
21 words
A leveling device according to claim 1 in which said pocket is trough-like and open at the front of the holder.
Claim 7
Dependent Claim
41 words
A leveling device according to claim 5 in which the rear wall of the pocket is wider than the front wall thereof in the vertical direction and slopes upwardly and forwardly to said mounting plate to form an obtuse angle therewith.
Claim 8
Dependent Claim
14 words
A leveling device according to claim 5 in which said pocket has end walls.
Claim 9
Dependent Claim
17 words
A leveling device according to claim 1 in which said mounting plate has a roughened back face.
Claim 10
Dependent Claim
22 words
A leveling device according to claim 1 in which said securing means comprises adhesive on the front face of said mounting plate.
Claim 11
Dependent Claim
20 words
A leveling device according to claim 1 in which said mounting plate has adhesive on its front and back faces.
Claim 12
Dependent Claim
114 words
A leveling device comprising: a mounting plate, a wall sloping downwardly and rearwardly at an obtuse dihedral angle from the bottom of the mounting plate, a level tube carried by the wall at the front and bottom portion thereof, and guide means projecting forwardly at the top of the wall for properly positioning the mounting plate on an object to be leveled, said wall having a reduced cross-sectional area at the bottom of the mounting plate whereby the wall, guide means and level tube may be readily severed from the mounting plate by applying a force against the front of the mounting plate while the lower end of the wall bears against a support.
Claim 13
Dependent Claim
114 words
A leveling device comprising: a mounting plate, a wall sloping downwardly and rearwardly at an obtuse dihedral angle from the bottom of the mounting plate, a level tube carried by the wall at the front and bottom portion thereof, and guide means projecting forwardly at the top of the wall for properly positioning the mounting plate on an object to be leveled, said wall having a reduced cross-sectional area at the bottom of the mounting plate whereby the wall, guide means and level tube may be readily severed from the mounting plate by applying a force against the front of the mounting plate while the lower end of the wall bears against a support.
