Edger Resurfacing Machine

Abstract

An edger machine for treating a floor and other surfaces has a housing with a motor and a deck. The motor has a drive shaft extending into an upper deck section of the deck. A pulley is positioned forward of the drive shaft, and a drive belt connects the drive shaft to the pulley. The pulley is constructed to mount a resurfacing disc in a lower deck section of the deck. A pair of guide wheels is mounted on an upper surface of the lower deck section adjacent the upper deck section. The guide wheels are rotatable about a vertical axis and positioned such that the wheels can roll against a vertical surface.

The embodiments in which an exclusive property or privilege is claimed are defined as follows: 
     
         1 . An edger machine for treating a floor and other surfaces comprising:
 a housing;   a motor mounted to said housing and having a drive shaft;   said housing having a deck with an upper deck section housing said drive shaft, a pulley positioned forward of said drive shaft, and a drive belt connecting said drive shaft to said pulley;   said pulley constructed to mount a resurfacing disc in a lower deck section of said deck;   a pair of guide wheels mounted on an upper surface of said lower deck section adjacent said upper deck section; and   said guide wheels rotatable about a vertical axis and positioned such that said wheels can roll against a vertical surface.   
     
     
         2 . An edger machine as defined in  claim 1  further comprising:
 said guide wheels being mounted for linear adjustment between a fore and aft position. 
 
     
     
         3 . An edger machine as defined in  claim 1  further comprising:
 said guide wheels mounted on a bracket that is slidably mounted with respect to said deck. 
 
     
     
         4 . An edger machine as defined in  claim 1  further comprising:
 said upper deck extending more than 11 inches forward of said drive shaft and having an upper surface set lower than 3.06 inches high. 
 
     
     
         5 . An edger machine comprising:
 a deck with least one resurfacing disc and motor operably mounted thereto;   said deck having an upper deck section housing a drive shaft of a motor, a pulley positioned forward of said drive shaft, and a drive belt connecting said drive shaft to said pulley;   said pulley constructed to mount a resurfacing disc in a lower deck section of said deck;   said lower deck section positioned below a distal forward position of said upper deck section and having a rear wall forwardly positioned from a rear wall of said upper section; and   said rear wall of said lower section having a vacuum exit and a vacuum duct extending rearwardly therefrom.   
     
     
         6 . An edger machine as defined in  claim 4  further comprising:
 said vacuum duct passing through said upper deck section and having an exit port at said rear wall of said upper deck section. 
 
     
     
         7 . An edger machine as defined in  claim 6  further comprising:
 said vacuum exit being positioned in the lateral center of said rear wall of said lower section. 
 
     
     
         8 . An edger machine for treating a generally horizontal surface comprising:
 a housing mounting a motor, deck, and drive system for mounting resurfacing discs;   a main frame mounted to said housing and travel wheels;   a castor frame assembly pivotably mount to said main frame for moving said castor frame assembly between a stored position and a surface engaging position;   said castor frame assembly having a subframe pivotably adjustable thereto for adjusting said subframe with respect thereto;   a castor wheel is mounted to said subframe such that said castor wheel is pivotable with respect to said castor frame assembly and said subframe is angularly adjustable on said castor frame assembly to adjust the axis of rotation of said castor wheel to be perpendicular to said generally horizontal surface.   
     
     
         9 . An edger machine as defined in  claim 8  further comprising:
 said castor frame assembly being a first plate member; 
 said subframe having a second plate member hinged to said first plate member; and 
 said second plate being adjustable with respect to said first plate member via a turn screw which adjusts the spacing of the two plates away from the hinge.
