Abstract
Abstract This disclosure is of a skidboard to be affixed to appliances for cushioned support, which skidboard comprises a corrugated board core having top and bottom facing sheets affixed to the core with holes drilled through the sheets and core to receive bolts to affix the skidboard to the appliance, the board core being depressed for a portion of its depth around the holes to provide solid bases and stable cushions for the heads and washers of the bolts to be screwed through the skidboard into the base of the appliance. This disclosure also includes the method of making such skidboard to provide the bases and cushions in the board.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
139 words
A skidboard to be affixed to and support an appliance comprising: a core of built-up glued corrugated board of uniform thickness with the flutes running normal to the top and bottom of the core; top and bottom facing sheets affixed to the top and bottom edges of the core; first holes drilled through the said sheets and core to receive bolts to affix the skidboard to the base of the appliance; second holes larger than the first holes drilled through the bottom sheet to create areas around the first holes; the board of the core above the said areas being matted and compressed for a portion of the depth of the core to create solid bases and stable cushions for the heads and washers of the bolts to be screwed through the skidboard into the base of the appliance.
Claim 2
Dependent Claim
139 words
A skidboard to be affixed to and support an appliance comprising: a core of built-up glued corrugated board of uniform thickness with the flutes running normal to the top and bottom of the core; top and bottom facing sheets affixed to the top and bottom edges of the core; first holes drilled through the said sheets and core to receive bolts to affix the skidboard to the base of the appliance; second holes larger than the first holes drilled through the bottom sheet to create areas around the first holes; the board of the core above the said areas being matted and compressed for a portion of the depth of the core to create solid bases and stable cushions for the heads and washers of the bolts to be screwed through the skidboard into the base of the appliance.
Claim 3
Dependent Claim

Claim 6
Independent Claim
219 words
The method of making a skidboard to be affixed to and support an appliance having a corrugated board core with top and bottom facing sheets, holes drilled through the core and sheets to receive bolts to affix the skidboard to the base of the appliance and solid bases and stable cushions in the core around the holes for the heads and washers of the bolts comprising: affixing top and bottom facing sheets to the top and bottom edges of a core of built-up corrugated board of uniform thickness with the flutes running normal to the said facing sheets; drilling first holes through the said sheets and core to receive bolts to affix the skidboard to the base of the appliance; drilling second holes larger than the first holes through the bottom sheet to create areas around the first holes; counter punching the board of the core above the said areas while the glue adhering the sheets of corrugated board together is in a wet condition to depress the board for a portion of its depth; whereby the board around the first holes is matted and compressed when the glue dries and hardens to create solid bases and stable cushions for the heads and washers of the bolts to be screwed through the skidboard into the base of the appliance.
Claim 7
Independent Claim
219 words
The method of making a skidboard to be affixed to and support an appliance having a corrugated board core with top and bottom facing sheets, holes drilled through the core and sheets to receive bolts to affix the skidboard to the base of the appliance and solid bases and stable cushions in the core around the holes for the heads and washers of the bolts comprising: affixing top and bottom facing sheets to the top and bottom edges of a core of built-up corrugated board of uniform thickness with the flutes running normal to the said facing sheets; drilling first holes through the said sheets and core to receive bolts to affix the skidboard to the base of the appliance; drilling second holes larger than the first holes through the bottom sheet to create areas around the first holes; counter punching the board of the core above the said areas while the glue adhering the sheets of corrugated board together is in a wet condition to depress the board for a portion of its depth; whereby the board around the first holes is matted and compressed when the glue dries and hardens to create solid bases and stable cushions for the heads and washers of the bolts to be screwed through the skidboard into the base of the appliance.
