摘要： Mating connectors enable a vacuum cleaner section to be releasably attached to a toolbox section. The connectors include a downward-facing tongue that fits in a corresponding horizontal slot. The tongue has a vertical slot that corresponds with a vertical flange adjacent the slot. An interacting tab and slot prevent the vacuum cleaner section from being removed from the toolbox section when a closeable top on the toolbox section is closed. The two sections attach in a position in which upright side walls on the vacuum cleaner section align with the upright sides on the toolbox section, and an extended horizontal work surface is formed by portions of the hinged top on the toolbox section and the vacuum cleaner section. A handle on the vacuum cleaner section can form part of the horizontal work surface, which has parallel lateral grooves with co-linear segments on opposite sides of a recessed channel. A wheeled version has a handle hinged to a mount and a pocket that encircles and supports the vacuum cleaner section. Another version has a handle that retracts into the recessed channel and is arranged to support the top against the ground when the top is fully open.
摘要翻译：配合连接器使真空吸尘器部分可拆卸地连接到工具箱部分。连接器包括配合在相应的水平槽中的朝下的舌头。舌头具有垂直槽，其对应于与槽相邻的垂直凸缘。当工具箱部分的可关闭顶部关闭时，相互作用的接头和插槽可防止吸尘器部分从工具箱部分移除。两个部分附接在真空吸尘器部分上的直立侧壁与工具箱部分上的直立侧对准的位置，并且延伸的水平工作表面由工具箱部分上的铰接顶部的部分和真空吸尘器部分。真空吸尘器部分上的手柄可以形成水平工作表面的一部分，其具有在凹陷通道的相对侧上具有共线的段的平行横向槽。轮式版本具有铰接到安装件的手柄和环绕并支撑真空吸尘器部分的口袋。另一个版本具有缩回凹入通道的手柄，并且被布置成当顶部完全打开时将顶部抵靠地面支撑。

摘要： A vacuum cleaner has a screen cage that is permanently attached to a lid that fits on a receptacle. The screen cage has multiple layers of screens with different screen sizes, including an inner support that has greater rigidity and larger apertures that the primary screen, and an outer screen that also has greater rigidity and larger apertures than the primary screen, and is made of a different material than the support. A replaceable filter mounts to a power head that can be removed from the lid while the lid remains attached to the receptacle, and nests in the screen cage. A thermal cutoff shuts the vacuum cleaner off when the temperature of air in a part of the flowpath exceeds a limit.
摘要翻译：真空吸尘器具有永久地连接到安装在容器上的盖的屏幕保持架。屏幕保护架具有多层不同屏幕尺寸的屏幕，包括具有较大刚性和较大孔径的内部支撑件，主屏幕和外屏幕还具有比主屏幕更大的刚度和更大的孔径，并且由不同于材料的支撑。可替换的过滤器安装到动力头上，可以在盖子保持连接到容器的同时将其从盖子上取下并嵌入到筛网笼中。当流路的一部分空气温度超过极限时，热断路器关闭真空吸尘器。

摘要： A retainer clip for retaining components on a shaft eliminates the need for a threaded shaft and a hex nut to retain the components on the shaft. The retaining clip includes a main body having a through hole for accommodating the shaft, a plurality of teeth for engaging the shaft and projecting radially inwardly from the main body and a plurality of spring members projecting in a direction transverse to the main body.

摘要： An electric motor brush subassembly includes a housing base, a housing cover, a brush, and a constant force spring. The brush is mounted between the housing base and the cover with the coil of the spring mounted adjacent to the outer end of the brush. The axis of the coil is disposed at a right angle with respect to the length of the brush and an unrolled spring segment extends along a side of the brush and is fixed in a slot in the cover. The spring exerts a force against the brush to bias the brush against the motor commutator.
