Abstract

The invention disclosed herein is a debris bag for a push-type lawn comber. Such a lawn comber is representative of similar devices such as lawn mowers and sweepers, in are provided with a rearwardly extended push handle. The lawn comber carries an array of radial impact arms upon a transverse shaft within the body of the comber. Rotation of the shaft and impact arms upon it by a power drive throws debris through a chute at the rear of the machine. A bag is carried upon a frame which latches itself to the chute and cantilevers rearwardly from the chute to define the top of the bag. A closure cover fits over this bag top to enclose it when the unit is n operation. A lever is used to engage the impact arm shaft with the power drive. Whenever the lever is depressed rearwardly alongside the bag, engagement occurs. A finger on the bag frame holds the lever in place and thus sustained engagement of the shaft impact arm shaft with the power drive is not possible unless the bag is in proper position upon the lawn comber.

In combination with a lawn comber, or the like, having a rearward discharge chute wherethrough debris is discharged with the exit portion of the discharge chute being a generally rectangular opening formed by an upper plate, a lower plate and sidewall plates, a debris bag attached to said exit portion to extend rearwardly therefrom to receive debris, and comprising:

a. a body of pliable, cloth-like sheet material having a generally rectangular bottom disposed near the ground surface below the exit portion of the discharge chute, a front wall extending upwardly from the front edge of the bottom and to said lower plate, side walls extending upwardly from the respective side edges of the bottom to a top edge portion above the top of the discharge chute with the front edges of the side walls at the adjacent sides of said sidewall plates and a rear wall extending upwardly from the rear edge of the bottom to the top edges of the sidewalls to complete the bag form, and
b. a bag frame including an upright section attached to the exit portion of the discharge chute and a bag supporting section having rearwardly extended longitudinal top rods connected by a rear transverse cross rod, corresponding with the bag form, being cantilevered from the top of the upright section and being connected with the top edge portions of the sidewalls and rear wall of the bag body to suspend the bag body in an open debris-receiving position.
