✅ SOLVED Knob of some sort?

[cudamark]

Found at an old home site. It says "New" on one side and "Worn" on the other. The hole on the back side appears to have a flat side, so, Probably fit on a shaft that turned. I'm trying to think of something that would need a special setting between new and worn! Any ideas?

Seen that before can't remember what from, maybe it will come to me.

I figured it out, it is the end of a vacuum brush roller if you need to change the belt you would have seen it.It is called a beater brush end cap.From Eureka models.If you pull out the center part where the hole is you will find it to be hair that wrapped up in there.

So, either a sewing machine or vacuum cleaner part eh? Why would either machine care if the cloth/carpet is new or worn? Both cloth and carpet come in all kinds of thicknesses and naps. Since I don't use either one, I'm totally ignorant in this area!

Back of the Boat is correct. Its from a Eureka vacuum roller end. Its a different fit for new or worn belt I think.

I had one in the 80s

Here is what I thought, sewing machine part---

Its definitely from a vintage Eureka upright vacuum cleaner. I remember this part every time I removed the roller to clean out the hair.

Its from this vacuum. Either Hoover or Eureka. Its the end cap of the roller.

So, this knob would change the tension on the belt depending on new or used belt? I guess after you put a new belt on, you would have to turn the knob to the used setting after you ran it a while?

Yes I think thats it. Somebody may still have this vacuum and can take a pic. I dont have it anymore.

 

[Bigcypresshunter]

I cant find a pic

Yes but it isn't a knob it is the end cap.You would spin the beater brush around 180 degrees while you had it out of machine then slide it back into the slots on the side of the bottom of the vacuum head.

It wasn't for the carpet being new or worn it was for the roller belt of the vacuum.

Here is a pic of a newer beater brush with end cap although the newer one is plastic.Put it in one way when new belt flip 180 when worn.

 

[Bigcypresshunter]

Yes its not a knob. Its the end cap for the vacuum roller. I circled its location in red. You would turn it 180 and reinsert it, it would be tighter.

Thanks folks, I'll consider this one solved!

Hey Cudamark... you might too young to remember these. There was a little rubber belt that made the beater go around. After the vacuum ran for a while the belt would stretch... and become loose, then it would slip and the beater would not work like it is supposed to. You could switch that piece around to "tighten" the belt, so the beater would spin again. After it got loose again, you switch it for a new tighter belt.
