Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
176 words
An apparatus for tiltably connecting a storage device to a drafting table and the like, comprising: a first threaded rod member, a second threaded rod member aligned with and spaced from said first rod member and having an eye portion at one end, a first bar member slidably disposed about said rod members, a second bar member slidably disposed about said rod members and alignedly spaced from said first bar member, a first pair of nut members each threadedly and compressively disposed on said first rod member for urging one of said bar members toward the other of said bar members, a second pair of nut members each threadedly and tensionally disposed on said second rod member for urging one of said bar members from the other of said bar members, support means for storing and holding selected objects, and connector means for pivotally interconnecting said support means with said eye portion of said second rod member for positioning said support means independently relative to the positions of said first rod member and said bar members.
Claim 2
Independent Claim
176 words
An apparatus for tiltably connecting a storage device to a drafting table and the like, comprising: a first threaded rod member, a second threaded rod member aligned with and spaced from said first rod member and having an eye portion at one end, a first bar member slidably disposed about said rod members, a second bar member slidably disposed about said rod members and alignedly spaced from said first bar member, a first pair of nut members each threadedly and compressively disposed on said first rod member for urging one of said bar members toward the other of said bar members, a second pair of nut members each threadedly and tensionally disposed on said second rod member for urging one of said bar members from the other of said bar members, support means for storing and holding selected objects, and connector means for pivotally interconnecting said support means with said eye portion of said second rod member for positioning said support means independently relative to the positions of said first rod member and said bar members.
Claim 3
Dependent Claim
69 words
The apparatus described in claim 1, wherein said first nut members are disposed to apply compression within and along the longitudinal axis of said first rod member adjacent the center portions of said bar members, and wherein said second nut members are disposed to exert tension within and along the longitudinal axis of said second rod member adjacent one of the end portions of each of said bar members.
Claim 4
Dependent Claim
41 words
The apparatus as described in claim 2, wherein said second nut members are further disposed on said second rod member for driving said bar members pivotally of said first nut members and into engagement with said drafting table and the like.
Claim 5
Dependent Claim
