Abstract
Abstract Method for preparing wall covering prior to placement of the wall covering on a wall, the method relying upon a laterally expandable frame and a plurality of work surface panels removably mounted upon the frame. The frame can be oriented in either a generally horizontal or an upright position disposed at any one of a plurality of angles with respect to the vertical. Wheels mounted upon one end of the frame accommodate lateral movement when the frame is in the upright orientation and are restrainable so that in the upright orientation, the apparatus can be easily displaced in only a side-to-side direction. A guide for the wall covering dispenses wall covering over the assembled work surface segments at a controlled rate.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
88 words
In a method of installing wall coverings, the steps of: adjusting the size of an expandable work table having an exposed work surface to a size on the order of the size of any selected one of several different sizes in wall coverings to be installed, retaining the selected work table size, placing the work table in a generally horizontal attitude, disposing the wall covering on the work table, preparing the wall covering for application to a wall, and moving the work table to a generally erect attitude.
Claim 2
Dependent Claim

In a method of installing wall coverings, the steps of: adjusting the size of an expandable work table having an exposed work surface to a size on the order of the size of any selected one of several different sizes in wall coverings to be installed, retaining the selected work table size, placing the work table in a generally horizontal attitude, disposing the wall covering on the work table, preparing the wall covering for application to a wall, and moving the work table to a generally erect attitude.
Claim 3
Dependent Claim
27 words
In a method as defined in claim 1 wherein said adjusting step comprises relatively telescopically displacing frame members to alter the transverse dimension of the work table.
Claim 4
Dependent Claim
52 words
In a method as defined in claim 1 wherein said moving step is preceded by adjusting the angular orientation of floor engaging wheels of the work table causing the exposed work surface to be disposed at any desired one of a plurality of acute angles with respect to the vertical when erect.
Claim 5
Dependent Claim
55 words
In a method as defined in claim 1 wherein said moving step is followed by changing the orientation of said wheels and thereafter displacing the work table laterally in a direction generally parallel to a plane comprising the vertical projection of the work surface while restraining movement of the work surface in any other direction.
Claim 6
Dependent Claim
37 words
In a method as defined in claim 1 further comprising the step of adjusting the height of the work table above the floor, when in its generally horizontal attitude, to any one of a plurality of heights.
Claim 7
Dependent Claim
67 words
In a method as defined in claim 1 further comprising the steps of mounting a supply of wall covering upon the frame, directing the wall covering from its frame mounting to the work surface through opposed guide means, and biasing the opposed guide means toward one another to control the rate at which the wall covering can be displaced through the guide means to the work table.
