摘要： A motor manufacturing and its method of assembly are disclosed. The motor includes lower and upper end frames with bearings, an armature assembly rotatably mounted in the bearings of the lower and upper end frames, and a winding field assembly supported between the lower and upper end frames and surrounding the armature assembly. The method includes the steps of inserting one end of the armature assembly into the bearing of the lower end frame, positioning the winding field assembly over the armature assembly while also stacking the winding field assembly on the lower end frame, stacking the upper end frame on the winding field assembly while also positioning an opposite end of the armature assembly into the bearing of the upper end frame, and securing the lower end frame, winding field assembly and upper end frame to each other. Motor brush and brush holder assemblies are also secured to the upper end frame in a novel releasable locking arrangement, in order to provide self compensating adjustment of the brushes relative to a commutator that surrounds the armature assembly.
摘要翻译：公开了一种电动机制造及其组装方法。电动机包括具有轴承的下端框架和上端框架，可旋转地安装在下端框架和上端框架的轴承中的电枢组件以及支撑在下端框架和上端框架之间并围绕电枢组件的绕组现场组件。该方法包括以下步骤：将电枢组件的一端插入下端框架的轴承中，将绕组磁场组件定位在电枢组件上，同时将绕组磁场组件堆叠在下端框架上，将上端框架堆叠在绕组磁场组件，同时将电枢组件的相对端定位到上端框架的轴承中，并将下端框架，绕组磁场组件和上端框架彼此固定。电机刷和电刷架组件也以新颖的可释放锁定装置固定到上端框架，以便相对于围绕电枢组件的换向器提供电刷的自我补偿调整。

In one embodiment, the collection canister has substantially cylindrical ends and substantially flatter sides. A collection canister lid is adapted to engage the canister around a top perimeter thereof, supporting the canister such that the lid cooperates with the canister to resist the collapse of the canister when subjected to vacuum forces resulting from operation of the vacuum.

摘要： A snap together wet nozzle for use with a vacuum cleaner is disclosed. The snap together wet nozzle includes an elongated U-shaped nozzle housing with closed ends including a connecting tube passageway for association with the vacuum cleaner. An elongated squeegee is mounted within the elongated U-shaped housing and is held in releasable locking engagement between a locking squeegee bar and the elongated U-shaped housing. The locking squeegee bar has a plurality of spaced squeegee prongs for reception within spaced complementary configuring openings in the elongated squeegee element, the spaced squeegee prongs being cooperatively engaged by a plurality of spaced prong receptacles formed in the elongated U-shaped nozzle housing. Complementary releasable locking means are associated with the elongated U-shaped nozzle housing and the locking squeegee bar for releasably holding the locking squeegee bar and associated elongated squeegee element relative to the elongated U-shaped nozzle housing.

摘要： A wheeled hand cart for use with a wet/dry utility vacuum cleaner drum is disclosed. A pair of wheel frames are mounted to the drum in spaced relationship to each other along a lower outer periphery of the drum. Each wheel frame has a horizontally extending passageway and a vertically extending channel that intersects and extends across each horizontally extending passageway. An upright handle section is positioned within the vertically extending channel of each wheel frame and has a transverse opening which is in alignment with the horizontally extending passageway of each wheel frame. Horizontally extending passageways of the spaced wheel frames are in alignment with one another to receive a wheel axle extending therethrough and also through the transverse openings of the upright handle sections. The wheels are mounted on the wheel axle for wheeled movement of the hand cart. A handle interconnects the upright handle sections to facilitate movement of the drum by the wheeled hand cart. The interconnecting handle and upright handle sections are also associated relative to the drum and an overlying drum cover in order to provide a stable and secure mounting of the wheeled hand cart relative to the drum.
