Abstract

A combined bulb and vegetable planter which is spring loaded to allow the user to readily remove a plug of soil from the ground, either for the purpose of planting vegetables and disposing of the plug of soil or planting a bulb and returning the plug of soil into the ground and over the planted bulb. In either operation, a plunger or cylinder is pressed into the soil by exerting a force on a foot rest attached to the cylinder or plunger. Extending vertically from the plunger or cylinder is a hollow tubing housing a shaft having a spring disposed about a portion thereof between a spring tension collar and an alien screw for compressing the spring when desired. A gripping handle is provided near the upper end of the vertically extending hollow tubing for the purpose of being gripped by the user of the invention. Extending above this gripping handle is a knob handle with brass plug and alien screw, and further, having a rubber compressions spacer which forms the operating mechanism for the spring.

Dependent claims

A gardening tool for removing soil from the ground preparatory to plainting a bulb or vegetables comprising:

(a) a vertically extending housing;
(b) a shaft extending vertically and co-axial with and disposed within said housing;
(c) a spring disposed about a portion of the length of said shaft;
(d) a slot formed vertically in said housing along a portion thereof;
(e) a horizontally extending upper handle attached to said housing near its upper end;
(f) a horizontally extending depression member attached to said housing near its lower end distant from said upper handle;
(g) a plunger attached to said depression member and extending vertically downwardly therefrom;
(h) a plunger plate disposed at the upper end of said plunger, thereby closing this end of said plunger;
(i) a second plunger plate movably attached to the lower end of said shaft for movement therewith up or down inside said plunger once the shaft moves up or down;
(j) a knob handle operatively attached to the upper end of said shaft;
(k) means disposed about said shaft and attached thereto for preventing downward movement of said spring;
(l) a spring tension collar depending from said knob handle and attached to said housing above said upper handle for receiving the upper end of said spring;
(m) a screw threaded into said shaft through said slot for slidable movement up or down therein as said shaft moves up or down responsive to movement of said knob handle;
and,
(n) at lease one depth dent formed in said housing and cooperating with said slot such that said screw will engage said depth dent when said knob handle is rotated when said screw is aligned with said depth dent, thereby holding said spring, said shaft, and said second plunger plate in place such that when said depression member is pushed downwardly into said soil, said plunger will fill with soil up to the position of said second plunger plate.
