摘要： A walk-behind, self-propelled lawn mower having a variable speed drive transmission responsive to operator-applied forces. The transmission includes an input gear operatively connected to the engine for constant rotation during operation, an intermediate gear meshed with the input gear, and a driving bevel gear meshed with a drive shaft bevel gear. A face of the driving bevel gear is biased away from a face of the intermediate gear. A clutching surface is interposed between the gear faces for coupling the intermediate gear and the driving bevel gear in driving engagement. An actuator lever is controllably connected to the intermediate gear and can be adjusted to vary the sensitivity of the drive transmission to operator-applied forces.

摘要： A vacuum cleaner having an improved transmission. The transmission includes speed reduction gearing and forward and reverse clutching elements which provide high power capacity, large speed reduction, durability, quiet operation and smooth power engagement. The main power train elements all rotate on parallel axes and the forward and reverse clutching elements are essentially independent of one another and resistant to wear. The transmission has an actuating mechanism which is connected to an upright handle on the vacuum cleaner and allows the appliance to respond to moderate pushing or pulling forces applied to the handle by the user. The vacuum cleaner also has improved bearings for rotatably supporting the wheel shaft of the appliance and aligning itself to the housing of the appliance.

摘要： A convertible vacuum cleaner providing a detachable upright handle permits the vacuum cleaner to be used as an upright cleaner for cleaning rugs, carpets, and the like. A detachable portable hand cleaner handle is also provided which is mounted when the cleaner is to be used as a portable hand cleaner. A resiliently biased, releasable connector is mounted on the filter bag to detachably connect the filter bag to either of the handles. The connector is connected to the upright handle. The connector is resiliently connected to the bag so that the bag remains in proper extended position in all operating positions of the upright handle. A receiver having a socket and a mating blade on the handles permits the two handles to be selectively mounted on the power unit of the cleaner. The portable handle provides a shoulder strap which is retracted into the handle by a reel when not in use and is locked at any selected extended position when the shoulder strap is in use.

摘要： A self-propelled vacuum cleaner adapted to be used in an upright mode or, alternatively, in a portable mode. The vacuum cleaner includes a power transmission for self-propelling the vacuum cleaner when used in the upright mode. The vacuum includes a first handle usable during operation in the upright mode and control structure arranged to energize the transmission in response to manually applied pulling or pushing forces on the first handle. The vacuum cleaner further includes a second handle usable during operation in the portable mode and arranged to prevent the control structure from energizing the transmission during operation in the portable mode.

摘要： A vacuum cleaner having a powered brush roll with a one-piece thread guard and mounting portion. The thread guard is a molded thermoplastic element which encloses the adjacent end of the brush roll and the bearing mounted in such adjacent end. The thread guard provides a skirt extending around the adjacent end of the brush roll and is held against rotation with the brush roll by a mounting portion. The mounting portion of the thread guard provides a sound-deadening mounting structure for the brush roll. The skirt is initially sized to frictionally fit the adjacent end of the brush roll and, after initial relative rotation between the skirt and the brush roll, provides a zero clearance fit to prevent string, thread and other debris from entering the bearing zone. During initial operation, the heat softens the thermoplastic material of the skirt, causing it to wear away and deform until frictional contact is eliminated and a free running condition occurs. The frictional contact is eliminated when a zero clearance fit is provided. The brush roll body is wood, which tends to change dimensionally with changes in ambient humidity. If the brush roll body expands slightly during the use of the vacuum cleaner, frictional contact is re-established and the thread guard automatically wears to re-establish a zero clearance free running condition.
摘要翻译：一种具有动力刷辊的真空吸尘器，其具有一体式螺纹防护件和安装部分。螺纹防护罩是模制的热塑性元件，其围绕刷辊的相邻端部并且轴承安装在相邻的端部。螺纹防护罩提供围绕刷辊的相邻端部延伸的裙部，并通过安装部分与刷辊保持抵抗旋转。螺纹护罩的安装部分为刷辊提供了消音安装结构。裙部最初的尺寸设计成摩擦配合刷辊的相邻端，并且在裙部和刷辊之间的初始相对旋转之后，提供零间隙配合以防止绳，线和其它碎屑进入轴承区。在初始操作期间，热软化裙部的热塑性材料，导致其磨损和变形，直到消除摩擦接触并发生自由运行状态。当提供零间隙配合时，消除摩擦接触。刷辊体是木材，其随着环境湿度的变化而趋向于尺寸变化。如果在使用真空吸尘器时刷辊体稍微膨胀，则会重新建立摩擦接触，螺纹防护罩自动磨损以重新建立零间隙自由运行状态。

摘要： A walk-behind, self-propelled lawn mower having a variable speed drive transmission responsive to operator applied forces. The drive transmission is mounted on a frame and comprises gearing operatively connected to an engine and a drive shaft for transmitting forces from the engine to the shaft. A clutching structure including a frictional coupling is coactable with an element of the gearing selectively to provide force transmission to the drive shaft. An actuator structure is controllably connected to the clutching structure and responsive to operator applied forces for controlling the speed at which the lawn mower traverses along a ground surface and to vary the speed proportionally to operator applied forces. The lawn mower also includes a handle pivotally connected to the frame and operatively connected to the actuator structure. The handle is adapted to pivot in response to the operator applied forces.

摘要： A disposable dust bag for vacuum cleaners and the like is disclosed which includes a mounting collar adapted to be removably mounted on a vacuum cleaner connector through which dirt-laden air is delivered to the dust bag. The connector has a generally cylindrical outlet end and peripherally spaced projections extending from the outer surface thereof. The collar provides an opening sized to closely fit the outlet through the majority of its peripheral extent and which provides peripherally spaced enlarged portions adapted to clear the projections on the connector when the bag is installed and removed. The collar also provides an inwardly extending elastomeric diaphragm having a centrally located opening substantially smaller than the outlet of the connector. During installation and removal of the bag on the connector, the enlarged portions of the collar opening are aligned with the projections on the connector and the collar is pressed over the connector until it is positioned behind the projections. The collar is then rotated to a mounted or installed position in which it engages the rearward sides of the projections to secure the two members together. The elastomeric diaphragm tightly fits around the projections and forms a lip seal with the connector to prevent leakage of dirt-laden air back along the connector.
摘要翻译：公开了一种用于真空吸尘器等的一次性防尘袋，其包括适于可移除地安装在真空吸尘器连接器上的安装环，通过该真空吸尘器连接器将污浊的空气输送到集尘袋。连接器具有大致圆柱形的出口端和从其外表面延伸的周向间隔开的突出部。套环提供一个开口，该开口的尺寸适于通过其大部分外围区域紧密地配合出口，并且当安装和移除袋时，该开口提供适于清除连接器上的突起的周向间隔开的扩大部分。套环还提供向内延伸的弹性体膜片，其具有基本上小于连接器出口的中心定位的开口。在安装和拆卸连接器上的袋子的过程中，套环开口的扩大部分与连接器上的突起对准，并且套环被压靠在连接器上，直到其位于突出部分的后面。然后将套环旋转到安装或安装的位置，在该位置中它与突起的后侧接合，以将两个构件固定在一起。弹性隔膜紧密地配合在突起上并与连接器形成唇形密封，以防止污垢附着的空气沿连接器返回。
