16 words
The invention as defined in claim 1, wherein said elongated bar has a circular cross section.
Claim 4
Dependent Claim
36 words
The invention as defined in claim 1, and further including a pair of gussets each attached to said elongated bar and each attached to the front of said horizontal plate base for reinforcing the elongated bar.
Claim 5
Dependent Claim
