摘要： Apparatus for mounting a rotatable component on a rotating shaft using a non-machined torque transmitting intermediate hub member is disclosed. The hub member makes torque transmitting contact with the drive shaft and transmits that torque to the rotatable component through frictional contact at a taper on the drive shaft and at a recessed shoulder of the hub as well as by an external key on the hub periphery and a matching cut-out formed in the rotatable member. There is also a keyway and key between the drive shaft and hub for accurate alignment in assembly and disassembly. A plurality of narrow longitudinally extending rib members are integral with and are supported on the other peripheral surface of the hub member whereby the rotatable member when it is seated against the shoulder on the hub member for the first time mechanically distorts the rib members from their original shape to provide a secure but releasable fit between the hub member and the rotatable component. A nut and washer assembly secure the rotatable component and hub member to the drive shaft.

摘要： The present invention is directed to an internal combustion engine-powered, blower/vacuum device. The device has an air chamber with an axial air inlet and a tangential air outlet. The engine rotatably drives the impeller, and is controlled by a throttle. A handle is located above the air chamber and the motor, and includes a first section having an axis generally parallel to the axis of the air outlet, and an adjoining section having an axis which extends at an angle of about 15.degree. to 60.degree. to the first section. When the first section of the handle is gripped by an operator the device will be in the vacuum position with the air outlet in a generally horizontal position. When the second section of the handle is gripped, the device will be in the blower position with the air outlet facing ahead of the operator at a downward angle. The impeller and housing of the device is designed to minimize debris hangup within the housing. The impeller blades have a front edge facing the air inlet extending at an angle to the impeller blade radial plane from the vicinity of the impeller hub to the vicinity of the air inlet. The portion of the air inlet closest to the front edge of the impeller is separated therefrom by a distance of from 0.15 inches to 0.27 inches, to reduce debris hangup in the inlet while maintaining good impeller efficiency.
摘要翻译：本发明涉及一种内燃机动力的鼓风机/真空装置。该装置具有具有轴向空气入口和切向空气出口的空气室。发动机可旋转地驱动叶轮，并由节流阀控制。手柄位于空气室和电动机的上方，并且包括具有大致平行于空气出口的轴线的轴线的第一部分和具有轴线的相邻部分，该轴线以大约15°至60°的角度延伸至第一部分。当手柄的第一部分被操作者抓住时，装置将处于真空位置，而空气出口处于大致水平的位置。当手柄的第二部分被抓住时，装置将处于鼓风机位置，其中空气出口面向操作者的前方向下倾斜。设备的叶轮和外壳设计用于最大限度地减少外壳内的碎屑挂起。叶轮叶片具有面向空气入口的前边缘，其与叶轮叶片径向平面成一定角度，从叶轮毂附近到空气入口附近。空气入口最靠近叶轮前缘的部分与0.15英寸至0.27英寸的距离分开，以减少入口中的碎屑悬挂，同时保持良好的叶轮效率。

摘要： An automatic two-way centrifugal clutch having a pair of clutch members mounted for pivotal movement on a rotating drive member is disclosed. Each clutch member has a first state in which driven surfaces are in contact with a clutch drum interior friction drive surface; a second state in which the clutch members are out of contact with the drum frictional drive surface; and a third state in which clutch driving surfaces are in driving contact with the frictional drive surface. At least two spring members are connected between the clutch members, the springs urging, when the speed of rotation of the drive member is below a first selected speed, the clutch driven surfaces against the frictional drive surface. When the rotational speed of the rotating drive member is greater than the first selected speed, centrifugal force overcomes the spring force and urges the clutch members, which are mounted symmetrically with respect to the rotation axis, to pivot to a position wherein the clutch driven surfaces are out of engagement with the frictional drive surface. If the rotation speed is greater than a second selected speed, the centrifugal force urges the clutch driving surfaces into driving contact with the frictional drive surface. By an appropriate choice of springs and spring position, a significant and distinct idle range, which is substantially independent of the device manufacturing tolerance, is defined.
摘要翻译：公开了一种具有一对离合器构件的自动双向离心式离合器，用于在旋转驱动构件上枢转运动。每个离合器构件具有第一状态，其中被驱动表面与离合器鼓内部摩擦驱动表面接触; 第二状态，其中离合器构件与鼓摩擦驱动表面脱离接触; 以及其中离合器驱动表面与摩擦驱动表面驱动接触的第三状态。在离合器构件之间连接有至少两个弹簧构件，当驱动构件的旋转速度低于第一选定速度时，弹簧推动离合器驱动表面抵靠摩擦驱动表面。当旋转驱动构件的旋转速度大于第一选定速度时，离心力克服弹簧力并促使相对于旋转轴对称安装的离合器构件枢转到离合器驱动表面与摩擦驱动表面脱离接合。如果旋转速度大于第二选定速度，则离心力促使离合器驱动表面与摩擦驱动表面驱动接触。通过适当地选择弹簧和弹簧位置，定义了基本上与装置制造公差无关的显着和不同的怠速范围。

摘要： A comminuting apparatus for garden waste consists of a cutter support plate rotating about a vertical axis in a cutter housing provided with a laterally directed outlet channel. The support plate includes cutting slots and slicing cutters thereabove. The support plate further includes at least one dependent discharge blade located on the underside thereof. At least one spiral deflecting vane is mounted on the cutter housing beneath the support plate. Upon rotation of the cutter support, the cutting slots and slicing cutters cooperate to direct comminuted material downwardly through the support plate, while the dependent discharge blade and the spiral deflecting vane cooperate to force comminuted material out through the laterally directed outlet channel.
