Abstract: An exhaust fan for use in bathrooms or similar areas has a generally rectangular fan housing formed from two independent structural members to reduce manufacturing waste and decrease production cost. The fan housing includes a receptacle panel that can be installed and removed from within the housing without additional tools. The fan housing includes two series of spaced view holes formed in its back wall such that during installation of the exhaust fan, the installer can view the ceiling joist to correctly position the fan housing relative to the bottom surface of the joist. The back wall of the fan housing also includes a pair of bend down tabs that can be placed in contact with the bottom surface of the joist to correctly position the bottom edge of the fan housing the required distance from the joist to accommodate the most common drywall thickness.

Abstract: A ventilator for a cooking unit located in a counter has a housing suitable for mounting beneath the counter. A vent member moves in a generally vertical direction with respect to the housing between a retracted position in which said vent member is flush with the counter and an extended position in which the vent extends above the counter adjacent to the cooking unit. The vent member is in fluid communication with said housing. A blower is coupled to said housing for drawing cooking effluents produced at the cooking unit into said vent member, downwardly through said vent member into said housing, and discharging same from said ventilator. A motor is mounted on the housing for moving a roller in an arcuate path. The roller engages a follower surface mounted on the vent such that travel of the roller along the follower surface drives the vent to the extended position.

Abstract: A friction disc transmission including a conventional drive disc rotatable about a vertical axis and a vertical friction disc engaging the top horizontal face of the drive disc to be driven about a horizontal axis. The driven friction disc is rotatably supported between a fixed frame member and a floating plate member. The floating plate member is lifted or lowered by a bellcrank having a pin that is movable within a slot in the floating plate member. A clutch pedal is connected to the bellcrank for pivoting the bellcrank thereby raising and lowering the floating plate member and driven disc. The bellcrank pin is biased by a spring which is connected to the bellcrank to apply a downward normal force on the floating plate member and driven disc. Guide pins are provided on the floating plate member which are engageable with guide brackets to limit the vertical movement of the floating plate member.

Abstract: A self-elevating wood splitter is disclosed which includes an arrangement for selectively adjusting the vertical position of the wood-supporting frame of the splitter. The splitter includes a height adjusting arrangement which generally comprises a pair of four-bar linkages, and further includes an elevating mechanism which permits the hydraulic actuator of the splitter to be employed for operating the height adjusting arrangement to effect raising and lowering of the splitter's frame. A locking mechanism is provided which includes a pair of adjustment members operatively associated with the height adjusting mechanism of the splitter. Notably, the arrangement operates such that the wood-supporting frame can be raised by operation of the elevating mechanism before selective adjustment of the locking mechanism is effected.

Abstract: The disclosed friction disc transmission includes a conventional drive disc rotatable about a vertical shaft and a vertical friction disc engaging the top horizontal face of the drive disc to be driven about a horizontal axis. The friction disc is rotatably supported on a pivot frame having a sprocket drive connected to a sprocket on the wheel axle. The vertical drive disc shaft is mounted on a transversely swingable support for movement of the drive disc relative to the driven friction disc and control of the rotational speed and direction of the driven disc. The support includes a control plate having camming surfaces which lift the driven disc over the center neutral axis of the drive disc, reducing wear of the driven disc when the transmission is in neutral. The control also includes a clutch-brake mechanism independent of the control plate including a lever connected to a rotatable link means.

Abstract: The disclosed chute assembly is particularly adapted to collect the discharge from a rotary lawn or garden tractor, particularly a mower having a vertically adjustable rotary blade housing. In the disclosed embodiment, the chute between the blade housing and the hopper has two telescopically adjustable sections, including a discharge chute which is pivotally supported on the hopper opening lip and a spiral receiving chute which is fixed to and communicates with the blade housing. The mower blade may thus be adjusted vertically without affecting the chute assembly and the chute sections may be easily removed for cleaning, storage or repair.

Abstract: An oscillating gear ratchet drive unit transmits rotating motion and torque from a drive gear to a driven shaft in a preselected direction of rotation and includes a shaft and a gear operably connected to a drive gear and positioned transversely with respect to the shaft and supported by the shaft. Ratchet crown wheels are provided on the opposing major faces of the gear and have camming surfaces for producing axial movement of the gear on the shaft, with each camming surface terminating in an axial surface. Pins project radially outwardly from the shaft adjacent to each ratchet crown wheel and engage an axial surface to the drive shaft, and are adapted to engage the camming surfaces to move the gear axially whenever the shaft rotates faster than the gear, while also accommodating and limiting axial movement of the gear on the shaft.
