Abstract
Abstract This disclosure relates to a sheeting arrangement for the sheeting or shoring of a ditch or trench wherein vertical supports are driven into the ground and thereafter sheeting walls are placed between the vertical supports with the sheeting walls having relative vertical movement with respect to the supports during the positioning and pulling thereof. In order to facilitate the movement of the sheeting walls relative to the supports without undue binding or frictional resistance, it has been proposed to provide the connections between the sheeting wall and the support with bearing like elements.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
181 words
An apparatus comprising sheeting means for the shoring of ditches, said sheeting means including vertical posts of a hollow box-like profile, sheeting walls, and guide heads carried by each of said sheeting walls in vertically spaced relation and guided in said posts, each post having at least one leg disposed normal to the plane of an adjacent one of said sheeting walls and inner and outer legs disposed parallel to tHe plane of adjacent ones of said sheeting walls, said guide head having a plurality of rollers, some of said rollers being mounted for rotation on axes disposed normal to the plane of a respective sheeting wall in engagement with said one leg and others of said rollers being mounted for rotation on axes extending within the plane of the respective sheeting wall between side surfaces thereof and perpendicular to an adjacent post, said other rollers being offset relative to the respective sheeting wall such that they run only on said inner leg of the respective post which inner leg will be adjacent to the center of a ditch being shored.
Claim 2
Independent Claim
181 words
An apparatus comprising sheeting means for the shoring of ditches, said sheeting means including vertical posts of a hollow box-like profile, sheeting walls, and guide heads carried by each of said sheeting walls in vertically spaced relation and guided in said posts, each post having at least one leg disposed normal to the plane of an adjacent one of said sheeting walls and inner and outer legs disposed parallel to tHe plane of adjacent ones of said sheeting walls, said guide head having a plurality of rollers, some of said rollers being mounted for rotation on axes disposed normal to the plane of a respective sheeting wall in engagement with said one leg and others of said rollers being mounted for rotation on axes extending within the plane of the respective sheeting wall between side surfaces thereof and perpendicular to an adjacent post, said other rollers being offset relative to the respective sheeting wall such that they run only on said inner leg of the respective post which inner leg will be adjacent to the center of a ditch being shored.
Claim 3
Dependent Claim
13 words
The apparatus of claim 1 wherein there are means resiliently mounting said rollers.
Claim 4
Dependent Claim
49 words
The apparatus of claim 2 wherein those rollers which are mounted for rotation on axes disposed normal to the plane of the respective sheeting wall are mounted in pairs with the rollers of each pair being mounted for rotation about a single axis and said rollers are part spherical.
Claim 5
Dependent Claim
49 words
The apparatus of claim 1 wherein those rollers which are mounted for rotation on axes disposed normal to the plane of the respective sheeting wall are mounted in pairs with the rollers of each pair being mounted for rotation about a single axis and said rollers are part spherical.
