摘要： This is a belt drive arrangement in which two belts are used, the inside surface of one running in contact with the outside surface of the other for part of their lengths and both running within the width of one belt, with input and output shafts, and one or more idler pulleys providing forward or reverse rotation of the output shaft with the input shaft having a constant direction of rotation.

摘要： This invention is concerned with a sweeper, meaning a sweeper with a rotary main brush opposite a hopper, and increasing its ability to load light debris, such as paper, dry leaves and the like so that light debris will be propelled farther into the debris hopper. This is done by setting the speed of the main brush at a lower speed for normal operation to effectively throw what may be thought of as heavier material, such as sand, forwardly into the hopper with the speed being such that excessive wear of the brush is avoided and a higher speed of rotation being effected from time to time so that paper, dry leaves and the like, which may be considered lightweight material, are thrown farther into the hopper with the increased speed of the main brush overcoming the air resistance that normally stops such lightweight material which, at normal operation of the brush, tends to pile up in the rear of the hopper. The sweeper uses a vacuum fan to create a suction in the hopper with the vacuum fan also being speeded up with the brush speed increase which assists in loading the lightweight debris in the hopper. Since the increased speed is used for the main brush and vacuum fan only from time to time when light debris is encountered and on a limited basis, the increased brush wear and power consumption caused thereby is tolerable.
摘要翻译：本发明涉及清扫机，这意味着具有与料斗相对的旋转式主刷的清扫机，并且增加其装载轻质碎片（如纸张，干叶等）的能力，使得光碎片将进一步推入碎屑料斗。这是通过将主刷的速度设置为较低的速度进行正常操作，以有效地将可能被认为是比较重的材料（例如砂）向前推入料斗中，速度使得刷子的过度磨损避免了并且更高的旋转速度不时地进行，使得可以被认为是轻质材料的纸，干叶等被提高到料斗中，同时主刷的速度增加，克服了正常的空气阻力停止这样的轻质材料，其在电刷的正常操作下倾向于在料斗的后部堆积。清扫机使用真空风扇在料斗中产生吸力，真空风扇也随着刷子速度的增加而加快，这有助于将轻质碎屑装载到料斗中。由于仅在遇到轻质碎片时有时才能将主速刷和真空风扇用于主刷和真空风扇，因此可以耐受由此引起的刷磨损和功耗增加。

摘要： A floor scrubber has rotating brushes for scrubbing a floor, drive motors for the brushes, and a brush height control circuit for raising and lowering the brushes in accordance with a desired brush pattern. The scrubber includes a solution tank, a recovery tank and a detergent tank for application and recovery of the cleaning solution. A solution tank pump, a detergent tank pump and a fan for use in vacuuming used cleaning solution into the recovery tank are each connected to their respective tanks. There are actuating means connected to the brush drive motors, pumps, fan and brush height control circuit. Sensors monitor the solution tank, recovery tank and detergent tank, as well as the speed of the floor scrubber. A start signal for the actuating means is only provided when the sensors determine certain prestart conditions have been met in the solution tank, recovery tank, detergent tank and a certain predetermined speed has been reached for the floor scrubber.
