Abstract
Abstract An earth auger comprises an open topped frame having a downwardly sloping floor leading to a discharge end opening having a pivoted closure door. A boss at the bottom of the tray mounts a downwardly extending hollow auger tube. Brackets above the tray mouth a motor unit and a thrust bearing. The motor unit engages the thrust bearing and drives a screw auger that extends downwardly through the tube; the screw auger has an enlarged downwardly through lower end so that the hole it cuts is larger than the auger tube.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
158 words
An earth auger comprising an auger tube having an operative upper end and an operative lower end and having an earth discharge opening adjacent the said upper end, means mounting an auger member in the tube for operative rotational movement therein to draw earth into the bottom end of the tube and to discharge it through the said opening, means for mounting a driving motor adjacent the said tube upper end for operative driving engagement with the said auger member, and a tray member mounted adjacent the said tube upper end to receive earth discharged through the said opening, wherein with the auger tube in an operative position the bottom of the tray member is inclined downwardly for the earth received therein to tend to collect at the lowermost portion thereof, and the said lowermost portion of the tray member is provided with an openable closure door and releasable means for retaining the door in the closed position.
Claim 2
Dependent Claim
158 words
An earth auger comprising an auger tube having an operative upper end and an operative lower end and having an earth discharge opening adjacent the said upper end, means mounting an auger member in the tube for operative rotational movement therein to draw earth into the bottom end of the tube and to discharge it through the said opening, means for mounting a driving motor adjacent the said tube upper end for operative driving engagement with the said auger member, and a tray member mounted adjacent the said tube upper end to receive earth discharged through the said opening, wherein with the auger tube in an operative position the bottom of the tray member is inclined downwardly for the earth received therein to tend to collect at the lowermost portion thereof, and the said lowermost portion of the tray member is provided with an openable closure door and releasable means for retaining the door in the closed position.
Claim 3
Dependent Claim
92 words
An earth auger as claimed in claim 1, wherein said means mounting the auger tube and the auger member and providing a tray member comprise an open-topped frame member constituting the said tray, a boss in the bottom of the frame member receiving the said auger tube with the upper end of the tube opening to the interior of the tray member and constituting the said earth discharge opening, and bracket means integral with the frame member and extending above the frame member for mounting the driving motor and the auger member.
Claim 4
Dependent Claim
29 words
An earth auger as claimed in claim 2, and comprising handle means extending generally horizontally from the said frame member for manual handling of the auger by an operator.
Claim 5
Dependent Claim
219 words
An earth auger comprising an auger tube having an operative upper end and an operative lower end and having an earth discharge opening adjacent the said upper end, means mounting an auger member in the tube for operative rotational movement therein to draw earth into the operative end of the tube and to discharge it through the said opening, means for mounting a driving motor adjacent the said tube upper end for operative driving engagement with the said auger member, a tray member mounted adjacent the said tube upper end to receive earth discharged through the said opening, the said tray member in operative position having the bottom thereof inclined downwardly for the received earth to collect at the lowermost portion thereof, an openable closure door at the said lowermost portion of the tray member, a boss in the bottom of the tray member receiving the said auger tube with the upper end of the tube opening to the interior of the tray member and constituting the said earth discharge opening, a bracket extending above the tray member, a thrust bearing mounted by said bracket to receive an auger member which extends through the auger tube and the thrust bearing, and means for mounting the driving motor in operative engagement with the auger member and the said thrust bearing.
Claim 6
Dependent Claim
219 words
An earth auger comprising an auger tube having an operative upper end and an operative lower end and having an earth discharge opening adjacent the said upper end, means mounting an auger member in the tube for operative rotational movement therein to draw earth into the operative end of the tube and to discharge it through the said opening, means for mounting a driving motor adjacent the said tube upper end for operative driving engagement with the said auger member, a tray member mounted adjacent the said tube upper end to receive earth discharged through the said opening, the said tray member in operative position having the bottom thereof inclined downwardly for the received earth to collect at the lowermost portion thereof, an openable closure door at the said lowermost portion of the tray member, a boss in the bottom of the tray member receiving the said auger tube with the upper end of the tube opening to the interior of the tray member and constituting the said earth discharge opening, a bracket extending above the tray member, a thrust bearing mounted by said bracket to receive an auger member which extends through the auger tube and the thrust bearing, and means for mounting the driving motor in operative engagement with the auger member and the said thrust bearing.
