A spinner for attachment to the hub of a spoked bicycle wheel generally comprises a body assembly and a contact for contacting a spoke for spinning the spinner about the hub. The body assembly comprises a bearing portion comprised of a plurality of individual bearing arc sections adapted for insertion between the spokes of the wheel and joined around the hub and radial display surfaces, either integral with the arc sections or attached to the bearing portion. The display surface may include an attachable radially outer portion of different wheel sizes and configurations.

Spinner for bicycle hub

A retainer maintains a body of standing washing liquid against the outside surface of a mat, such as a pulp mat. The mat moves on a vacuum screen which draws washing liquid from the body of liquid through the mat to clean it. The retainer pivots to adjust different mat heights and allows clumps of material on the mat to pass underneath the retainer. Clumps on the mat are also smoothed into the mat as the clumps pass underneath the retainer.

Method and apparatus for washing a porous mat

An improved stock washer for removing impurities from a porous mat disposed over a vacuum head is disclosed. In one application in connection with an industrial paper making process, paper pulp forms a porous mat over a rotating drum which has a vacuum on the inside. The washer includes an elongate housing, defining a chamber therein, disposed above the drum with a slot along its bottom and resilient, downwardly-extending wipers at the slot edges, Water flows into a pipe extending the length of the chamber. The pipe has holes along its sides to direct water into the chamber downwardly and outwardly. The pipe, which extends through the ends of the housing, is mounted to adjustable mounts at both ends to allow the washer height above the mat to be adjusted. Water flows through the holes in the pipe and accumulates at the chamber bottom where it is directed into the mat by the resilient wipers. The water flows through the mat into the drum displacing chemical impurities in the process. The wipers can be attached at an angle relative to the washer so that the washer may be placed other than centered directly above the drum while the chamber remains vertical, thus allowing a number of spaced apart washers to be used. A bracketing mechanism is also disclosed which allows the wipers to be easily attached to the washer.
