Abstract
A lawn rake consisting of an elongated frame bar carried for vertical tilting movement on a transverse axis by a pair of ground-engaging wheels, and having a handle at one end thereof and tines at its opposite end adapted to be moved into or out of engagement with the ground by tilting of the frame, and mechanism operable to adjust the elevation of the handle above the ground, the vertical movement of the handle required to produce the desired vertical movement of the tines, and the mechanical force with which the tines engage the ground.
Claims2
A lawn rake comprising:
- a. an elongated longitudinally extending frame consisting of a substantially horizontal front bar section and an inclined rear bar section which constitutes a handle,
- b. a generally horizontal transverse rake bar at the forward end of said frame,
- c. means securing said rake bar to said frame,
- d. rake tines carried by said rake bar and projecting downwardly therefrom,
- e. ground-engaging wheels carried rotatably by said frame intermediate its ends and operable to support said frame above the ground, whereby upward and downward movement of the handle end of said frame will respectively lower said tines to the ground and raise them above the ground,
- f. a weight carried by said frame intermediate said wheels and said tines, whereby to bias said tines against the ground, said weight comprising an open-topped container mounted on said frame and adapted to contain material of any desired density and mass, and
- g. means operable to permit adjustable forward and rearward movement of said container relative to said frame.

A lawn rake comprising:
- a. an elongated longitudinally extending frame consisting of a substantially horizontal front bar section and an inclined rear bar section which constitutes a handle,
- b. a generally horizontal transverse rake bar at the forward end of said frame,
- c. means securing said rake bar to said frame, said securing means being resiliently yieldable to permit transverse lateral tilting of said rake bar relative to said frame,
- d. rake tines carried by said rake bar and projecting downwardly therefrom,
- e. a pair of ground-engaging wheels carried rotatably by said frame on a horizontal transverse axis and disposed at respectively opposite sides of said frame,
- f. means permitting forward and rearward adjustment of said wheels relative to said frame, and
- g. a weight carried by said frame intermediate said wheels and said tines, whereby to bias said tines against the ground.
