-
Patent number: 4766641Abstract: A clutch mechanism for use in the drive mechanism for a vacuum cleaner floor cleaning rotary brush is provided which prevents damage to the drive belt in the event the brush becomes jammed and is prevented from rotating. A cam ring having external bumps carried on resilient beams is nested inside a driven sprocket with the bumps positioned in valleys between ridges formed on the interior of the sprocket. A pair of end caps sandwich the assembly of the cam and sprocket. The cam is keyed to the rotary brush and thus when the brush becomes jammed, the sprocket will continue to rotate, and the torque applied between the sprocket and cam will cause the ridges to push radially inwardly against the bumps and beams of the cam permitting the bumps to pass over the ridges dissipating the energy of the rotating sprocket.Type: GrantFiled: December 31, 1985Date of Patent: August 30, 1988Assignee: Whirlpool CorporationInventor: Terry D. Daglow
-
Patent number: 4766642Abstract: A decorative handle which is attachable to a rotatable stem and has a decorative insert held therein is disclosed.

A collar member which is threaded onto the handle from the bottom provides the force to hold the retainer in place. A decorative handle is provided which can be assembled and disassembled without tools, yet is highly aesthetic as the engagement of the component parts is obstructed from view as is a portion of the attachment to the valve assembly. Further, the inserts can be readily changed when the room where the handle is placed is remodeled.Type: GrantFiled: August 31, 1987Date of Patent: August 30, 1988Assignee: Kohler Co.Inventors: Thomas E.

Patent number: 4766645Abstract: An apparatus for controlling the stuffed casing diameter includes shoes which ride against the stuffed casing to monitor its diameter. These shoes drive a digital encoder which issues pulses representing deviations of the stuffed diameter from a predetermined nominal value. A microcomputer process these pulses and issues an appropriate control signal to a stepping motor for increasing and decreasing drag on the casing as may be needed to correct the stuffed diameter of the casing. The microcomputer can include a delay so that each stuffed product is the reference for establishing the drag characteristics of the next product to be stuffed.Type: GrantFiled: April 16, 1987Date of Patent: August 30, 1988Assignee: Viskase CorporationInventors: Salvatore P.
