Abstract
The hair and thread cutting blade is related to the vacuum cleaner brush roller and cuts hair and thread into tiny pieces as it works its way past the thread guard on the ends of the brush roller preventing them from impeding the rotation of the brush roller.
Claims3
I claim a stationary cutting blade fitted into or over the outer circumference of the retaining wall of the sleeve bearing hollow seat on the brush roller end cap that is suitable to fit different size bearings in order to cut hair and threads that work past the thread guards on each end of the brush roller and prevent thread and hair from damaging the bearing or impeding the rotation of the brush roller
I claim a stationary cutter blade exceeding the width of the sleeve bearing by 1/32 inch comprised of spring steel that is sharp on both ends and held in place by the elasticity reserve applying tension out side the end cap or by the blade being imbedded into the end cap.
- a. the dimension of the cutting blade is designed to exceed the width of the end cap by no less than 1/32 inch and to match circumference of each end cap bearing retainer suitable to fit the multiple dimensions of different size bearings.
- b. the cutting blade may be constructed of an outside mounting ring over the sleeve bearing cup retaining ¾ radius of very thin spring steel with an extended or raised cutting blade that is sharp on both ends of the ¾ radius. The reversed mounting of this cutting blade is permissible since it cuts in either direction of the brush rollers rotation.
- c. the elasticity reserve of the attached spring steel cutting blade band applies tension to hold the cutter in place and allows for the fitting to embrace sizes larger than the resting circumference of the cutting blade band.
