Abstract
A lawn sweeper and bagger which increases the efficiency of the device by utilizing a Bernoulli Effect to increase the pickup capabilities of the device and which also permits handling of the bags more readily by positioning them on the front rather than on the rear of the machine.
Claims13
A lawn sweeper comprising:
- a) a platform having a front, rear sides and an axis of travel;
- b) said platform supported by front and rear wheels;
- c) a leaf pick-up mounted beneath said platform;
- d) a suction-blower motor assembly including a motor mounted on said platform rear above said leaf pick-up;
- e) said leaf pick-up connected to said suction-blower motor assembly;
- f) a pair of passageways in said leaf pick-up leading to said suction-blower motor assembly;
- g) said leaf pick-up having top, bottom, side and rear walls forming at said platform front a debris intake having a mouth;
- h) said leaf pick-up extending lengthwise of said axis of travel from said debris intake mouth to said platform rear and said suction-blower assembly;
- i) said leaf pick-up having a wedge-shaped baffle forming said pair of passageways;
- j) said baffle having a front end extending in the direction of said mouth for creating a Bernoulli Effect in said pair of passageways upon operation of said suction-blower motor assembly;
- k) said suction-blower motor assembly including a main duct in front of said motor;
- l) said main duct extending in a forward direction of the platform axis of travel and having at least one secondary duct forward of said motor and having means for securing a debris pick-up bag thereto in front of said suction-blower motor assembly;
- m) whereby when said suction blower motor assembly is operated and a bag secured to said at least one blower end, the debris will be sucked into said leaf pick-up and thence into said suction blower motor assembly and blown into said main duct and propelled into a bag secured to said at least one blower end.
