I'm too young to know what this is...

[Muddy Treats]

but i bought it anyways because i thought it was cool. My luck it's probably something used for gross things. Haha. I bought this a few years ago at a yard sale and always wanted to know how old it is and what it was used for. Thanks for helping me out.

I think that is called a positive pressure flow meter used in lab experiments.

It is a spritzer,used for spraying a light coat of liquid. I used one to spray bananna oil on model airplanes. Bob

What is the name printed on the rubber squeeze ball?

[mojjax]

Could it be for removing chest cavity fluid ?

With the dip tube going all the way to the bottom I agree it is for spritzing or squirting. Something for vacuum purposes would have a shorter internal tube on it.

It would be used for bursts, or squirts for sure but wouldn't be a measured amount since the bulb can be squeezed unevenly. Also, if the bulb were "pumped" to pressurize the container for liquid flow it still wouldn't be a constant since the pressure would decrease over time and affect the flow rate.

Look and see if there are ANY markings on it, if so post a pic of them and I'll bet it gets an ID quickly.

VERY good point, this could be an early nebulizer.

The creme color bulb looks like a babies aspirator (snot sucker)

It's just an old water bottle. Squeezing the rubber ball repeatedly increases the pressure inside the jar, forcing water up the spout. Simple yet effective.

Atomizor for spraying plants. Cira 1920-1940.

Thanks for all the replies and ideas. On the rubber part it says "Koraseal" or "koroseal". Hope this helps.

[Mackaydon]

The entry below suggests the oldest date (at least for the rubber bulb) is 1933.
"The vinyl product is odorless, weatherproof, age- and acid-resistant, when rolled into a ball it bounces down a hallway, and it will be introduced commercially in 1933 under the name Koroseal."
Koroseal is associated with B . F. Goodrich.

We use one at the church where I work to fill the communion cups. You will fill the bottle with the grape juice and squizze the bubble to fill the the cup. When you let go of the bubble the juice flow stops, this allows the cups to be filled perfectly with out spilling. I know several other churches use them too. I think that they are sold in most church supply catloges. It is a old design but still works great.
