Abstract
Abstract A lock out assembly for a circuit breaker which consists of a generally step-shaped unitary base with an aperture in the small portion of the step-shaped base and a roughly "S" shaped retaining pin which loops through the large portion of the step-shaped base. The lock out assembly is adapted to fit over a circuit breaker with the handle switch projecting through the aperture, and the retaining pin projecting into an opening of the handle switch, preventing removal.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
73 words
A lock out assembly comprising: a generally step-shaped unitary base with an aperture in a small portion of the step-shaped base; and a roughly "S" shaped retaining pin which loops through a large portion of the step-shaped base whereby the lock out assembly is adapted to fit on a circuit breaker with a switch handle projecting through the aperture, and the retaining pin projecting into an opening of the switch handle, preventing removal.
Claim 2
Dependent Claim
73 words
A lock out assembly comprising: a generally step-shaped unitary base with an aperture in a small portion of the step-shaped base; and a roughly "S" shaped retaining pin which loops through a large portion of the step-shaped base whereby the lock out assembly is adapted to fit on a circuit breaker with a switch handle projecting through the aperture, and the retaining pin projecting into an opening of the switch handle, preventing removal.
Claim 3
Dependent Claim
44 words
The lock out assembly of claim 1, further including a projection on a surface which mates with the circuit breaker and is positioned adjacent the aperture, whereby the projection fits within the switch handle opening of the circuit breaker, preventing lateral and longitudinal movement.
Claim 4
Dependent Claim
41 words
The lock out assembly of claim 1, wherein a semicircular groove is cut into an upper surface of the small portion of the step-shaped base, which groove extends from a side of the unitary base to a side of the aperture.
Claim 5
Dependent Claim
33 words
The lock out assembly of claim 1, wherein the roughly "S" shaped retainer pin forms an opening with the unitary base of sufficient size to accomodate a padlock or a hasp and padlock.
Claim 6
Dependent Claim
22 words
The lock out assembly of claim 1, wherein said retainer pin is made of metal or plastic which can be fused together.
Claim 7
Dependent Claim
25 words
The lock out assembly of claim 1, wherein the base is made of any lightweight material, such as aluminum, nylon, fiberglass or any suitable plastic.
Claim 8
Dependent Claim
84 words
A lock out assembly for a circuit breaker having a switch handle comprising: a generally step-shaped base with an aperture in a lower portion of the base and a roughly "S" shaped retaining pin through an upper portion of the base, wherein said step-shaped base is adapted to fit over said circuit breaker with the switch handle extending through said aperture, and wherein said retaining pin is adapted to slide into an orifice in the handle switch thus preventing movement of the switch handle.
Claim 9
Dependent Claim
84 words
A lock out assembly for a circuit breaker having a switch handle comprising: a generally step-shaped base with an aperture in a lower portion of the base and a roughly "S" shaped retaining pin through an upper portion of the base, wherein said step-shaped base is adapted to fit over said circuit breaker with the switch handle extending through said aperture, and wherein said retaining pin is adapted to slide into an orifice in the handle switch thus preventing movement of the switch handle.
Claim 10
Dependent Claim
32 words
The lock out assembly of claim 7, further including a projection on a bottom surface of the lock out assembly which mates with the circuit breaker and is positioned adjacent the aperture.
Claim 11
Dependent Claim
40 words
The lock out assembly of claim 7, wherein a semicircular groove is cut into an upper surface of the lower portion of the step-shaped base, which groove extends from a side of the base to a side of the aperture.
Claim 12
Dependent Claim
32 words
The lock out assembly of claim 7, wherein the roughly "S" shaped retainer pin forms an opening with the base of sufficient size to accomodate a padlock or a hasp and padlock.
Claim 13
Dependent Claim
22 words
The lock out assembly of claim 7, wherein said retainer pin is made of metal or plastic which can be fused together.
Claim 14
Dependent Claim
25 words
The lock out assembly of claim 7, wherein the base is made of any lightweight material, such as aluminum, nylon, fiberglass or any suitable plastic.
Claim 15
Dependent Claim
80 words
A safety lock out assembly for an electrical circuit breaker comprising the combination of a circuit breaker, including a switch handle having a transverse orifice therein; and a unitary step-shaped base, with a lower portion of the step-shaped base including an aperture, an upper portion of the step-shaped base including a retaining pin, wherein said lock out assembly mounts upon the circuit breaker with the handle projecting through said aperture allowing said retaining pin to project within said transfer orifice.
Claim 16
Dependent Claim
80 words
A safety lock out assembly for an electrical circuit breaker comprising the combination of a circuit breaker, including a switch handle having a transverse orifice therein; and a unitary step-shaped base, with a lower portion of the step-shaped base including an aperture, an upper portion of the step-shaped base including a retaining pin, wherein said lock out assembly mounts upon the circuit breaker with the handle projecting through said aperture allowing said retaining pin to project within said transfer orifice.
Claim 17
Dependent Claim
31 words
The lock out assembly of claim 13, further including a projection on a bottom surface of the lockout assembly which mates with the circuit breaker and is positioned adjacent the aperture.
Claim 18
Dependent Claim
40 words
The lock out assembly of claim 13, wherein a semicircular groove is cut into an upper surface of the lower portion of the step-shaped base, which groove extends from a side of the base to a side of the aperture.
Claim 19
Dependent Claim
32 words
The lock out assembly of claim 13, wherein the roughly "S" shaped retainer pin forms an opening with the base of sufficient size to accomodate a padlock or a hasp and padlock.
