SWEEPING MACHINE Filed April 22, 1968 United States Patent "ice 3,513,498 SWEEPING MACHINE Carl Olof Hjalmar Gustavsson Bennich, Ranas, Sweden, assignor to Industri Belos Aktiebolag, Rimbo, Sweden, a corporation of Sweden Filed Apr. 22, 1968, Ser. No. 722,851
Claims priority, application Sweden, Apr. 24, '1967,
Int. Cl. E01h 1/04 US. CI. -84 3 Claims ABSTRACT OF THE DISCLOSURE This invention concerns a sweeping machine of the kind comprising a horizontal rotatable brush cylinder which throws-the rubbish into a receiver placed at a distance above the ground, in which a tube is placed parallel with the brush cylinder between the latter and the receiver. The tube is supported by the ground in contact with the periphery of the brush and has a transverse bar passed therethrough with free radial play.
This invention relates to a sweeping machine comprising a horizontal brush cylinder which throws the rubbish into a receiving device. Beneath the receiving device there is a free space of suflicient height to prevent the receiving device, generally formed by the collecting trough of an elevator, to hit inequalities of the ground.
In order to prevent, that the rubbish is thrown through this space by the rotating brush, known sweeping machines are generally provided with a flexible screen hang ing freely between the brush and said space. It has also been suggested to use as a screen a roller mounted on oscillatable arms maintaining the roller on the ground at a distance in front of the brush cylinder. This roller picks up a certain amount of rubbish and flattens it onto the ground thereby reducing the grip of the brush on the material to be thrown up.
Rubbish and other particles hitting such screens fall down onto the ground and thereby reduce the sweeping and cleaning capacity of the machine.
According to this invention, a tube is arranged parallel with the brush cylinder between the same and the receiving device, said tube being supported by the ground in contact with the periphery of the brush cylinder and being longitudinally traversed with radial play by a transverse bar mounted onto the machine. This tube screens off the space beneath the receiving device towards the brush. This has shown effectively to reduce the drawbacks connected with known screen members. The tube rolls on the ground in front of the brush and is simultaneously driven round by the latter. The portion of the surface of the tube turned towards the brush moves upwards and feeds the rubbish adhering to the tube to the line of contact between the tube and the brush, from which the rubbish is thrown forwards and upwards into the receiving device.
3,513,498 Patented May 26, 1970 An embodiment of the invention is described with reference to the accompanying drawing, which shows a diagrammatic longitudinal section through the brush, the screening means and the receiving .means of a sweeping machine.
The brush cylinder 1 rotates in the direction indicated by the arrow 2 during the movement of the sweeping machine in the direction of the arrow 3. A tube 4 is freely and loosely traversed by a bar 5 to keep the tube within the range of its normal active positions, in which the tube 4 rests on the ground 6 and rolls over it while being simultaneously in contact with the brush 1 by which it is driven round in the direction of arrow 7. Forwardly of the tube 4 and at a space 8 above the ground there is the receiving trough 9 of a bucket elevator 10 moving in the direction of arrow 11. The rotation of the tube 4 in the direction of arrow 7 is produced by the rolling of the tube on the ground 6 and sustained by the action of the periphery of the brush cylinder 1. By this rotation of the tube 4 particles and pieces of rubbish adhering to the surface of the tube are fed upwards to the line of contact between the tube and the brush, the latter brushing these particles and pieces off the tube and throwing them over to the trough 9.
The tube 4 is preferably made of a relatively soft, elastic material able to resist shocks, such as rubber or the like.
What I claim is:
1. A sweeping machine, comprising a brush cylinder adapted to contact a ground surface and being rotatable about an axis extending in at least substantial parallelism with said ground surface; a receiver for matter swept ofl? said ground surface by said brush cylinder, said receiver having an elongated inlet spaced upwardly of said ground surface and away from said brush cylinder, extending lengthwise of the latter; an elongated rod mounted in the space between said brush cylinder and inlet and extending longitudinally of the former; and a tubular deflector surrounding said rod with freedom of play radially thereof in directions parallel and transverse to the plane of said ground surface, said deflector being in rolling contact with said ground surface and with said brush cylinder so as to be rotated by the latter.
2. A sweeping machine as defined in claim 1, wherein said tubular deflector is composed of elastically yieldable material.
3. A sweeping machine as defined in claim 2, wherein said elastically yieldable materials is an elastomeric material.
