Abstract
A planter for seeds and bulbs includes a tube assembly receiving a plunger which is reciprocable between retracted and extended positions. With the plunger in its extended position, a lower end thereof extends downwardly from the tube assembly for embedding a seed in the ground. A handle is mounted on an upper end of the plunger for operating the planter. A feed assembly includes a seed hopper mounted on an upper end of a conduit, the lower end of which is connected to a lower end of the tube for passing seeds thereinto. A spacing rod is provided for gauging the spacing between plantings.
Claims13
A planter for seeds and bulbs, which comprises:
- (a) a tube with upper and lower ends and a bore extending between and open at said ends;
- (b) a plunger having upper and lower ends and being reciprocably mounted within said tube bore for movement between a retracted position with said plunger lower end retracted within said bore and an extended position with said plunger lower end telescopically extending from said tube lower end, said plunger having a plunger extend stroke and a plunger bore;
- (c) handle means mounted on said plunger;
- (d) conduit means having upper and lower ends and a passage extending therebetween;
- (e) junction means joining said tube and conduit means lower ends with said tube bore and conduit means passage in communication;
- (f) said plunger lower end substantially filling said tube bore at said tube lower end whereby a seed located in said tube lower end is embedded by said plunger extend stroke;
- (g) spring means connected to said plunger and to said tube for biasing said plunger to its retracted position;
- and
- (h) spring mounting means in said plunger bore for mounting said spring to said plunger.
