Roof membrane and insulation removing device

Abstract

A roof membrane and insulation removing device including a wheeled frame having a pair of handlebars. A number of first cutting blades are secured to the front of the wheeled frame. Each one of the first cutting blades is rotatable about a substantially horizontal axis. A second cutting blade is secured to the wheeled frame between the first cutting blades and the handlebars. The second cutting blade is rotatable about a substantially vertical axis. A first motor is connected to the first cutting blades, for rotating same. A second motor is connected to the second cutting blade for rotating same.

1 . A roof membrane and insulation removing device, comprising: 
 a wheeled frame having a pair of handlebars;    a plurality of first cutting blades being secured to the front of said wheeled frame, each one of said first cutting blades being rotatable about a substantially horizontal axis; and,    a second cutting blade being secured to said wheeled frame between said first cutting blades and said handlebars, said second cutting blade being rotatable about a substantially vertical axis;    a first motor being connected to said first cutting blades for rotating same; and,    a second motor being connected to said second cutting blade for rotating same.    
   
   
       2 . A roof membrane and insulation removing device, comprising: 
 a wheeled frame having a pair of handlebars at the rear thereof;    a pair of drive wheels being secured to the rear of said frame below said handlebars for propelling said device over a roof;    a plurality of first cutting blades being secured to the front of said frame, each one of said first cutting blades being rotatable about a substantially horizontal axis; and,    a pair of second cutting blades being secured to said frame between said first cutting blades and said drive wheels, and said second cutting blades being positioned side by side and being rotatable about a substantially vertical axis;    a first motor being connected to said first cutting blades for rotating same;    a pair of second motors each being respectively connected to one of said second cutting blades for rotating same; and,    a pair of third motors each being respectively connected to one of said drive wheels for rotating same.    
   
   
       3 . A roof membrane and insulation removing device, comprising: 
 a wheeled frame having a pair of handlebars at the rear thereof;    a pair of drive wheels being secured to the rear of said frame below said handlebars for propelling said device over a roof;    a source of pressurized hydraulic fluid being secured to said frame;    a plurality of first cutting blades being secured to the front of said frame, each one of said first cutting blades being rotatable about a substantially horizontal axis; and,    a pair of second cutting blades being secured to said frame between said first cutting blades and said drive wheels, and said second cutting blades being positioned adjacent one another and being rotatable about a substantially vertical axis;    a first hydraulic motor being connected to said source of pressurized hydraulic fluid and being connected to said first cutting blades for rotating same;    a pair of second hydraulic motors each being connected to said source of pressurized hydraulic fluid and being respectively connected to one of said second cutting blades for rotating same; and,    a pair of third hydraulic motors each being connected to said source of pressurized hydraulic fluid and being respectively connected to one of said drive wheels for rotating same.
