A centrifugal blower apparatus includes a scroll-shaped housing with first and second air inlets which open to a blower chamber that is in fluid communication with an air outlet. The blower includes a motor to drive an impeller, wherein the motor is secured to a frame that is coupled with the housing in a manner to substantially enhance aerodynamic performance of the blower.

A motor mounting device includes a polymeric motor housing having a cylindrical housing section for receiving motor components including a rotor. The housing section incorporates a detent feature disposed along the interior surface, with the interior surface inclined to gradually converge in a distal direction. The housing further has a distal end section that includes a first bearing seat centered on the housing axis. A rotor retaining member has an annular outer surface terminating at an arcuate peripheral edge, and comprises a second bearing seat. The rotor retaining member is insertable distally into the cylindrical housing section, following insertion of a rotor, to engage the first and second bearing seats respectively with distal and proximal bearings on a rotor shaft, to secure the rotor for rotation relative to the housing. During such insertion, the retaining member outer surface and the interior surface of the cylindrical housing section interact to center the retaining member.

A motor stator mounting device includes a plastic motor housing having a cylindrical housing section for receiving the stator. Longitudinal ribs along an inside surface of the housing section are inclined to converge gradually in a distal direction, thus tending to center a stator inserted distally into the housing section. An annular stator retaining member includes a plurality of distally extending centering features. Outside surfaces of the centering features interact with an interior surface of the housing section to center the retaining member as it is inserted distally. Inside surfaces of the centering features interact with a proximal region of a previously inserted stator, such that distal insertion of the retaining member both axially positions and radially centers the stator relative to the cylindrical housing. The retaining member is secured to the housing with a series of sonic welds to positionally fix the stator inside the housing.

An air impeller with both sound attenuation and vibration isolation means in a compact assembly. Three muffler chambers are provided preceding the inlet to the impeller each with sound absorbing foam material and vibration isolators are provided at both inlet and discharge sides of the impeller.

A zero clearance bearing assembly comprising a housing defining a generally cylindrical bearing chamber with a pair of ball bearing units disposed therein. One unit is adjacent an axial thrust reaction surface of frusto-conical configuration and a shoulder on an associated shaft urges the unit into engagement with the surface. The other unit is press fit on the shaft and also has a shaft shoulder urging it toward the thrust surface. An air impeller on the shaft urges the same toward the other bearing unit and the thrust unit reacts to both the impeller load and an axial preload spring engaging the other bearing unit. One or both of the bearing units is provided with an improved radial preload device comprising a spring and a pair of circumaxially spaced reaction surfaces opposing the same.

A transparent safety device and pushing tool with an adjustable and reversible shoe member for depth and angle used to push, hold down, and guide work pieces through or over cutting devices. The adjustable and reversible shoe member can be removed and reassembled for use by either a right or left handed user, while keeping the user's hands, extremities, and clothing up and away in a much safer position with respect to the cutting device. The safety device and pushing tool has an elongated slot in the main member's lower front section that allows the main member to be rotated to the rear while still allowing the shoe member to remain flat on the rip fence, straight edge or guide bar at all times while being used. Also, should the tool receive minimal damage, it could be repaired by the user, eliminating constant replacement costs.
