摘要： A small floor scrubbing machine is powered by a centrally located battery pack, with a recovery tank for used scrubbing solution comprised of connected chambers located on four sides of and beneath the batteries, and a tank for clean solution in a lid over the recovery tank and batteries. A partial partition in the chamber behind the batteries effectively divides it into two chambers. A vacuum fan draws air and used solution into one rear chamber of the recovery tank and exhausts air to atmosphere from the other rear chamber. The extended airflow path from one rear chamber to the other around three sides of the battery pack allows mist and foam to settle out of the air stream before it reaches the vacuum fan inlet. The front and rear chambers provide plenum space to reduce the airflow velocity. Openings in the partition between the rear tanks bypass increasing amounts of air directly from one rear chamber to the other as the recovery tank fills with water, thus compensating for the diminishing airflow space above the water and controlling the velocity of the airflow. The arrangement provides improved foam control in the limited space available in a small scrubber, a constant center of gravity as the solution tank empties and the recovery tank fills during normal operation, and easy access to the recovery tank for cleaning.
摘要翻译：小型地板擦洗机由位于中心的电池组提供动力，其中包括用于洗涤溶液的回收罐，所述洗涤溶液包括位于电池四面和下方的连接室，以及用于在回收罐上的盖子中的清洁溶液的罐;以及电池在电池后面的室中的部分隔板有效地将其分成两个室。真空风扇将空气和使用的溶液吸入回收罐的一个后室，并从另一个后室排出空气至大气。从电池组的三个侧面的一个后室到另一个的延伸气流允许雾和泡沫在到达真空风扇入口之前从空气流中沉淀出来。前后室提供通风空间以减少气流速度。在后箱之间的分隔开口，当回收池充满水时，直接从一个后室向另一个后部空间间隔大量的空气，从而补偿水面上方的空气流量减少并控制气流的速度。该装置在小型洗涤器可用的有限空间中提供改进的泡沫控制，当溶液罐排空时恒定的重心，并且回收罐在正常操作期间填充，并且容易地进入回收罐进行清洁。

摘要： A floor scrubbing machine uses two parallel cylindrical scrub brushes. Each brush is rotated by a separate drive means, and these are at opposite ends of the brushes. This balances the weight of the drives so the brushes exert a uniform pressure on the floor. The brushes are axially offset enough that each brush extends out as far as the drive means of the other brush, thus permitting the machine to scrub close to a wall on either side. The brushes have a more aggressive bristle fill at their ends which extend out under the drive means, where only one brush is scrubbing the floor, so the appearance of the scrubbed floor is essentially the same where scrubbed by one brush as where scrubbed by two brushes.
摘要翻译：地板擦洗机使用两个平行的圆柱形洗刷刷。每个刷子通过单独的驱动装置旋转，并且它们在刷子的相对端。这样平衡驱动器的重量，使刷子在地板上施加均匀的压力。刷子被轴向偏移足够大，使得每个刷子延伸出直到另一个刷子的驱动装置，从而允许机器靠近两侧的壁。刷子在它们的端部具有更积极的刷毛填充，其在驱动装置下延伸出来，其中只有一个刷子在擦洗地板，所以洗刷的地板的外观基本上是相同的，由两个刷子擦洗的一个刷子擦洗。

摘要： A floor scrubbing machine has a chassis mounted on front and rear wheels and a scrub head attached to the front of the chassis by a system of articulated links. Structure is provided for absorbing the kinetic energy of the moving machine in the event that the scrub head strikes a fixed object. On impact the geometry of the linkage system causes the front wheels to be lifted off the floor, thereby quickly lifting considerable weight. Also, a pair of heavy springs stretch, and parts of the chassis deform elastically. By this structure the kinetic energy is absorbed within the machine. No heavy protective shrouds are needed, and a simple flange along the front edge of the scrub head housing provides adequate stiffness.

摘要： A collectorless vacuum fan for floor maintenance machines has a backplate with an inlet plate attached thereto in spaced relationship, and an impeller between the backplate and inlet plate. Both the backplate and the inlet plate extend radially beyond the periphery of the impeller. A shaft mounts the impeller for rotation. The inlet plate has a central opening providing air to the hub of the impeller. Vanes on the impeller discharge air out through a diffuser channel defined by the space between the inlet plate and the backplate outside the periphery of the impeller. Attachment elements for mounting the inlet plate on the backplate leave the diffuser channel substantially unobstructed so that air is discharged about the entire periphery of the impeller. The fan has increased air flow compared to a conventional fan having an integral collector housing and decreased noise compared to a fan having a 360 degree discharge and no diffuser.

摘要： The present invention provides an adjustment mechanism and methods for adjusting the alignment of a powered cylindrical brush mounted to a surface maintenance vehicle relative to a surface to be maintained or cleaned by the vehicle. The device is preferably disposed upon the idler-side of a powered rotating cylindrical brush assembly and the adjustment preferably occurs via use of an eccentric cam member providing a range or motion, or pivot location, through or about which the idler-side mounting location of the cylindrical brush may be adjusted to improve contact with the surface. The present invention enables such adjustment without decoupling the rotating brush from its couplings (both supportive and rotational coupling), and any coupling to a drive mechanism for driving the rotating brush into rotation. The rotating brush so adjusted will benefit from improved mechanical cooperation between the bristles of the brush and the surface to be cleaned. If at least two counter-rotating cylindrical brush assemblies are disposed on a single surface maintenance vehicle each may be adjusted with respect to the surface and to the other brush disposed therein. Another aspect of the present invention is to allow a single operator to perform brush taper adjustments without disassembly of any connecting components for operating the rotating cylindrical brush assembly during cleaning operations, including even the side covers or other brush mounting components and any drive gear associated thereto. The apparatus and methods of the present invention are intended to readily accommodate rapid adjustment in the course of surface cleaning operations by a single manual operator or technician preferably either by hand or via use of a single rudimentary adjustment instrument operating upon a single adjustable mounting location to change the state of the single adjustable mounting location from a partially-released state to a fully-coupled state.
