Abstract

Abstract A device for shredding and bagging leaves and other yard and garden waste which includes a chamber having a horizontal rotary blade and arranged close to the ground with an inlet opening at the top and a conduit at the side for discharge of the shredded material. Communicating with the inlet opening is a flaring ramp which extends downwardly into ground engagement at a shallow angle so that leaves and the like may be swept from the ground directly into the inlet opening. A shield in the form of a small housing open at the front communicates with the ramp to prevent direct vertical access to the blade in the chamber. After shredding, the material is discharged from the conduit into a receiving bag made of thin plastic or the like which is supported on the ground alongside the ramp.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 217 words
In a shredding and bagging machine for yard usage, the combination comprising a base of shallow cup shape having a bottom wall and a circular side wall defining a shredding chamber, transport means for supporting the base in horizontal position slightly upraised above the ground, a cover plate fitted to the base for enclosing the same, an engine mounted on the cover plate and having a drive shaft which extends into the base, a rotor mounted on the shaft including a blade having tip portions extending to the region of the sidewall, a plurality of stationary breaker members at spaced positions on the sidewall and having horizontal notches formed therein for registering with the tip portions of the blade, means including a discharge conduit penetrating the sidewall for forcible discharge of the shredded material, the cover plate having a receptacle for feeding material into the chamber, a ramp of flaring construction having sidewalls defining a narrow upper end and a wide lower end, and means for securing the ramp with respect to the receptacle so that the narrow end communicates with the receptacle and so that the wide end extends downwardly at a shallow angle into engagement with the ground thereby permitting leaves or the like lying on the ground to be swept upwardly into the receptacle.
Claim 2
Dependent Claim 217 words
In a shredding and bagging machine for yard usage, the combination comprising a base of shallow cup shape having a bottom wall and a circular side wall defining a shredding chamber, transport means for supporting the base in horizontal position slightly upraised above the ground, a cover plate fitted to the base for enclosing the same, an engine mounted on the cover plate and having a drive shaft which extends into the base, a rotor mounted on the shaft including a blade having tip portions extending to the region of the sidewall, a plurality of stationary breaker members at spaced positions on the sidewall and having horizontal notches formed therein for registering with the tip portions of the blade, means including a discharge conduit penetrating the sidewall for forcible discharge of the shredded material, the cover plate having a receptacle for feeding material into the chamber, a ramp of flaring construction having sidewalls defining a narrow upper end and a wide lower end, and means for securing the ramp with respect to the receptacle so that the narrow end communicates with the receptacle and so that the wide end extends downwardly at a shallow angle into engagement with the ground thereby permitting leaves or the like lying on the ground to be swept upwardly into the receptacle.
Claim 3
Dependent Claim 217 words
In a shredding and bagging machine for yard usage, the combination comprising a base of shallow cup shape having a bottom wall and a circular side wall defining a shredding chamber, transport means for supporting the base in horizontal position slightly upraised above the ground, a cover plate fitted to the base for enclosing the same, an engine mounted on the cover plate and having a drive shaft which extends into the base, a rotor mounted on the shaft including a blade having tip portions extending to the region of the sidewall, a plurality of stationary breaker members at spaced positions on the sidewall and having horizontal notches formed therein for registering with the tip portions of the blade, means including a discharge conduit penetrating the sidewall for forcible discharge of the shredded material, the cover plate having a receptacle for feeding material into the chamber, a ramp of flaring construction having sidewalls defining a narrow upper end and a wide lower end, and means for securing the ramp with respect to the receptacle so that the narrow end communicates with the receptacle and so that the wide end extends downwardly at a shallow angle into engagement with the ground thereby permitting leaves or the like lying on the ground to be swept upwardly into the receptacle.
Claim 4
Dependent Claim 217 words
In a shredding and bagging machine for yard usage, the combination comprising a base of shallow cup shape having a bottom wall and a circular side wall defining a shredding chamber, transport means for supporting the base in horizontal position slightly upraised above the ground, a cover plate fitted to the base for enclosing the same, an engine mounted on the cover plate and having a drive shaft which extends into the base, a rotor mounted on the shaft including a blade having tip portions extending to the region of the sidewall, a plurality of stationary breaker members at spaced positions on the sidewall and having horizontal notches formed therein for registering with the tip portions of the blade, means including a discharge conduit penetrating the sidewall for forcible discharge of the shredded material, the cover plate having a receptacle for feeding material into the chamber, a ramp of flaring construction having sidewalls defining a narrow upper end and a wide lower end, and means for securing the ramp with respect to the receptacle so that the narrow end communicates with the receptacle and so that the wide end extends downwardly at a shallow angle into engagement with the ground thereby permitting leaves or the like lying on the ground to be swept upwardly into the receptacle.
Claim 5
Dependent Claim 53 words
The combination as claimed in claim 1 which includes a housing fitted to the cover plate having side and top walls but open at the bottom for communication with the receptacle and open at the front, the sidewalls of the ramp being positioned and dimensioned to merge with the sidewalls of the housing.
Claim 6
Dependent Claim 22 words
The combination as claimed in claim 2, the housing including readily removable means for clamping the same in position over the receptacle.
Claim 7
