101	Convertible garden rake and cultivating tool	US779345	1977-03-21	US4091879A	1978-05-30	Edward Lomberk; Edgar C. Rosston
A hand garden tool generally in the form of a rake wherein all tines are individually vertically-adjustable upon the crossbar, some to different depths depending from the crossbar and alternate tines can be elevated or raised to allow the depending tines to astraddle vegetable plant or flower rows so the cultivating action is had by a single raking action or pass of the converted rake cultivating tool along the vegetable rows and so that the rows are cultivated on opposite sides at the same time. The vegetable or flower rows in the garden which are to be cultivated by the use of this tool can be spaced closer together and conserve upon ground space and the work required for the cultivator to keep a garden thereby greatly reduced. The tool can be inverted and worked from one side or the other with the alternate raised tines by less rows at a time and at times the pulling is being made in more tough ground. The tines are all made individually adjustable upon the crossbar but showing various structures to lock the individual tines in their adjusted positions. As the plant grows, the tines will be lowered to greater depths to adequately clear the tops of the plants that have grown even up to ten inches or more. The tines can take various forms and the locking structures of the tines can be varied for the different tine forms. One locking structure is made common to lock to all the adjusted tines onto the crossbar assembly in their individually-adjusted positions.
