摘要： A floor sweeper includes a housing sub-frame having a pair of end partitions which mount a brush for sweeping debris from the floor and drive wheels for supporting the sweeper and rotating the brush. The drive wheels are mounted on either side of the brush for free movement between loaded and unloaded positions against a pair of coupling wheels disposed at opposite ends of the brush axle in response to fore and aft translation of the sweeper over the floor. Each drive wheel mounting includes a curved wire spring having a pair of bent legs at opposite ends thereof. One leg is pivotally mounted to the end partition and the other leg rotatably mounts the drive wheel with its free end riding along an inclined ramp formed in the end partition. When the sweeper is moved in one direction the spring is compressed to urge the drive wheel into driving engagement with a coupling wheel to rotate the brush. When moved in the opposite direction, the drive wheel pivots on the one leg of its wire spring away from the coupling wheel to its unloaded position while at the same time the free end of the other leg of the wire spring rides up the ramp to compress the spring and thereby preload or urge the drive wheel back toward the coupling wheel.
摘要翻译：地板清扫机包括具有一对端部隔板的壳体子框架，其安装用于从地板清扫碎屑的刷子以及用于支撑清扫器并旋转刷子的驱动轮。驱动轮安装在刷子的任一侧，以响应于清扫机在地板上的前后翻译而在装载位置和卸载位置之间自由移动，抵靠设置在刷轴的相对端的一对联接轮。每个驱动轮安装件包括弯曲的线弹簧，在其相对端具有一对弯曲的腿。一条腿可枢转地安装在端部隔板上，而另一条腿可旋转地安装驱动轮，其自由端沿着形成在端部隔板中的倾斜斜坡。当清扫机沿一个方向移动时，弹簧被压缩以促使驱动轮与联接轮驱动接合以旋转刷子。当沿相反方向移动时，驱动轮在其线弹簧的一条腿上从耦合轮枢转到其卸载位置，同时线弹簧的另一条腿的自由端骑起斜坡以压缩从而将驱动轮预加载或推动回联接轮。

摘要： A pair of opposed bail stay members are frictionally mounted to the horizontal bar of a T-bar bail, with the stay members engaging the bail stud. The resultant assembly is inserted up through the central slot of the sweeper top and held in position by friction. The opposed stay members seal the top against penetration of dirt into the sweeper mechanism. The outer ends of the horizontal bail bar are received within slots formed in the end partitions of the sweeper sub-frame. The bail bar ends prevent inward movement of the partitions in the event the latter comes loose from the housing end walls. The opposed stay members form a channel for angular movement of the bail stud and with the channel being formed to provide at least one end detent and a central detent. The stay members are slightly flexible and the channel between detents is slightly narrower than the diameter of the bail stud. The detents themselves are dimensioned to be relatively free of the bail stud when the latter is in a detent position.
摘要翻译：一对相对的吊环撑杆构件摩擦地安装在T形吊篮的水平杆上，保持构件与吊钩螺栓接合。所得组件通过清扫机顶部的中心槽插入，并通过摩擦保持在适当的位置。相对的支撑构件将顶部密封以防止灰尘进入清扫机构。水平吊杆的外端接收在形成在清扫器子框架的端部分隔件内的槽内。在吊环从外壳端壁松开的情况下，吊环杆端部可防止隔板向内移动。相对的支撑构件形成用于吊钩柱的角运动的通道，并且通道形成为提供至少一个端部止动器和中心制动器。支撑构件稍微柔软，并且制动器之间的通道比吊钩螺栓的直径略窄。棘爪本身的尺寸被设计成当后者处于制动位置时相对没有吊环螺栓。

摘要： A fluid flow control valve according to the invention includes a base, a valve member, a trigger member and attachment means for attaching the trigger member to the valve member. The base includes a generally horizontal throat and a flange having an upwardly facing surface. The valve member has a stem, a flow level establishing member associated with the stem and biasing means for biasing the stem in a direction opposite to that in which the throat extends. The trigger member includes a pin configured to rotate against an inner end portion of the throat, a flange having a downwardly facing surface and an actuating portion. The biasing means acts in a direction through the attachment means to pull the actuating portion downwardly such that the flanges engage in order to retain the pin in the throat. In this manner, the valve may be assembled without the use of fasteners.

摘要： A liquid extraction surface cleaning apparatus has an upwardly opening recovery tank and a top for the tank which contains a suction fan having a suction inlet opening into the tank. A wand connects to a source of cleaning liquid and has a dispensing and pickup head that deposits liquid on the surface to be cleaned in response to actuation of a control valve and picks up dirty fluid. A water and air separator has an arcuate surface transverse of the flow path of the air and spent liquid which gently separates them into separate streams by diverting the cleaning liquid laterally away from the air stream. A shutoff valve for preventing recovered liquid in the tank from entering the suction fan is mounted in the recovery tank rather than to the suction inlet to avoid dripping dirty liquid onto the floor when the cover is removed. A handle is mounted internal the tank and additionally serves to strengthen the tank sidewalls.

摘要： A floor sweeper is constructed from a single integral plastic housing having a top and downwardly extending rear and end walls. The front end portion of the housing is uniquely formed with the front edge of the top set back from the sweeper periphery, said edge merging into an integral deflector which extends downwardly beneath the housing adjacent the rotary brusy. The lower extremity of the deflector is connected to the front peripheral housing portion by an integral platform which, together with the deflector, forms an elongated transversely extending trough-like channel on the upper exposed side of the housing front end. The channel has end walls which are spaced inwardly from the housing end walls to form downwardly facing wheel-receiving recesses. The front sweeper wheels are freely mounted on the ends of an axle which extends through the channel and its end walls, with the wheels being trapped within their respective recesses. The channel is provided with a removable cover of flexible stretchable material, both for appearances sake and to prevent dust and debris from entering the channel. The cover is resilient and further serves as a bumper for the front of the sweeper. A dust pan is disposed behind the rotary brush, with the top side of the pan bottom forming a floor having a raised transverse rib which helps prevent shifting of dust and debris either toward or away from the brush. The under side of the rib beneath the pan forms a slot which receives the axle for the rear sweeper wheels.
摘要翻译：地板清扫机由具有顶部和向下延伸的后壁和端壁的单个整体塑料外壳构成。外壳的前端部分是唯一地形成有从清扫器周边设置的顶部的前边缘，所述边缘汇合成一体的偏转器，该偏转器在壳体的下方向下延伸，邻近旋转的刷子。偏转器的下端通过一体的平台连接到前周边壳体部分，该平台与偏转器一起在壳体前端的上部暴露侧上形成细长的横向延伸的槽状通道。通道具有从壳体端壁向内隔开的端壁，以形成向下的轮容纳凹部。前清扫车轮自由地安装在轴的端部上，车轴通过通道及其端壁延伸，车轮被捕获在它们各自的凹部内。通道设置有柔性可拉伸材料的可移除盖，用于外观，并防止灰尘和碎屑进入通道。盖子是弹性的，并且还用作清扫机前部的保险杠。一个防尘盘设置在旋转刷的后面，锅底的顶侧形成具有升高的横向肋的底板，这有助于防止灰尘和碎屑朝向或远离刷子移动。在锅底下方的肋的下侧形成一个槽，其接收用于后部清扫车轮的车轴。

摘要： A unitary top-less peripheral frame is provided which holds substantially all the functional parts of the sweeper. The frame includes end walls carrying bearings which receive the ends of the brush roller shaft, with the said end walls being spring-like and flexible to permit easy insertion and removal of the shaft. The frame has brush bristle tufts mounted therein at the corners. A separate top is removably mounted to the peripheral frame, with the top carrying bail detent or stop elements which additionally extend downwardly and lock the top to the unitary frame while also holding the dust pan springs in place. The front and/or rear frame walls which extend between the said end walls form a debris-retaining wall. The frame provides a lip which is engageable by the pan edge and which seals the pan chamber and tends to increase the frictional forces between the sweeper wheels and the brush roller element.

摘要： A cleaning apparatus which is of a compact construction to facilitate easy manipulation and portability includes a housing enclosing a fluid pump and a vacuum fan and mounting upon opposite sides a recovery tank and a stowage panel. The stowage panel is adapted to stow the flexible wand having a nozzle when not in use. Also, the high voltage motor driving the vacuum pump is adapted to also act as half of a transformer in order to pick off the lower voltage needed for the low voltage motor driving the fluid pump.
