Abstract
The invention relates to wheeled raking machines which is rolled over the ground by a walking attendant. The raking device includes a raking head having a plurality of raking tines. The raking head is rocked back and forth to gather leaves ahead of the raking device. The rocking motion of the raking head is derived from a cam and linkage arrangement connected to the wheel. Thus, as the wheeled device is rolled over the ground the raking head is oscillated to rake the leaves.
Claims14
A wheeled raking device comprising:
- a. an elongated handle member for moving and steering said device;
- b. a first shaft member carried by said handle member;
- c. at least one wheel member carried on said first shaft member supporting said handle member above the ground;
- d. a transverse shaft rotatably carried across a lower end of said handle member;
- e. a raking head having a plurality of raking tines carried by said transverse shaft;
- f. connection means connected between said wheel member and said transverse shaft;
- and
- g. said connection means imparting a rocking motion to said transverse shaft to oscillate said raking head in a raking motion as said wheel member rolls along the ground surface;
- whereby said raking tines move in a raking motion to gather leaves and the like as said device is rolled along the ground.
6 more elements
A wheeled raking device comprising:
- a. a frame;
- b. a first shaft carried by said frame;
- c. a pair of spaced wheel members carried on said first shaft spacing said frame above the ground;
- d. handle means extending upwardly from said frame for exerting a moving force on said frame;
- e. a transverse shaft rotatably carried by said frame;
- f. a raking head defined by a plurality of raking tines carried by said transverse shaft;
- and
- g. connection means connected between one of said wheel members and said transverse shaft for rocking said transverse shaft to oscillate said raking head in a raking motion as said wheel members roll over the ground;
- whereby leaves and the like adjacent said raking head are gathered together ahead of said raking device by said raking motion.
6 more elements
A wheeled raking device comprising:
- a. a frame having a handle member for exerting a force to move said frame;
- b. a first shaft carried by said frame having at lease one wheel member carried thereon spacing said frame above the ground;
- c. a raking head defined by a plurality of raking tines carried by a transverse shaft extending across said frame and rotatably carried therein;
- d. connection means connected between one of said wheel members and said transverse shaft for imparting a raking motion to said transverse shaft and said raking head as said wheel members roll over the gound;
- e. said connecting means including a cam member operatively connected with one said wheel member and a cam roller/linkage assembly in cam following arrangement with said cam member as said cam member rotates with said wheel member to transmit said racking motion to said raking head;
- and
- f. said raking motion including a sudden lift of said raking head, a more sudden drop of said head, and a momentary dwell of said raking head as said head drops momentarily in the grass prior to lifting again;
- whereby leaves and the likee adjacent said raking head are gathered together ahead of said raking device by said raking motion.
