It is a bore guage, modern. I say modern because it has metric measurments on it. Most I have seen are divided into fractions of 1/8 in or even decimal.
Use: Insert the pointy end into a hole, cylinder, firearm bore. The depth it settles to is the diameter.
Mine is for gun bores, but same principle.

I was thinking, except the markings aren't right, that it could be a ring size measurer. Hmmm...may have to invent one like that. Easy to give to customers, and you don't have to have a big mandrel to slide the ring on to. Do I have to share the proceeds?? A ring isn't much different than a gun bore, you know. Except my fingers are a 4 gauge.

A.T.Ferrell currently makes seed and grain mills, so I am guessing it's a gauge to measure openings in some type of grain chute to control feed in or out of a mill or grinder.

Bore guage as stated. I delivered steel tube for years and we used similar. :thumbsup:

I agree , those other numbers are not millimeters. maybe screen / mesh sizes.

I think it was to measure the opening on a seed cleaner..depending on the size of the seed being cleaned would determine the opening .

Also have to go with hole gauge. Probably just some complimentary item given out by the grain store for advertising purposes. (Hi Gyps!! long time hunz :D)

I was curious about your "pointy ruler," so I stopped by for a look-see. I don't think anyone will argue that it's some kind of "taper gauge" as bigcypresshunter indicated. Which I agree with. And it appears to be a "handout" given to customers and clients who delt with the A.T. Ferrell Company. But I was mainly curious as to why, and for what purpose, your average client (farmer) might need one of those dohickies? So I did a little research on "grain cleaners" and similar-such items, and discovered they really didn't require a measuring device in their operation. Most already came with various sized screens for that purpose. Anyhoo, I stumbled onto bits of information from one source and then another, which gradually led me to the conclusion that those taper gauges (although useable for a variety of things) were primarily intended for the average person to measure an existing hole (or possibly one they intended to drill) so they would know in advance exactly what size bolt, screw, or drill bit to use. Which is something I could have benifited from a million times, because I'm the sort of guy who usually makes ten trips to the tool box just to find the right bolt or screw that I need.

Anyhoo, that's my "spin" on your pointy ruler thingy.

Oh, and don't go poking it into any electrical outlets!

I did a little research and discovered that metric measurments were adoped (in tools anyway) by the United States around 1960. It seems to have something to do with the influx of foreign made cars. :dontknow:

So we all agree, you stick in a hole. But when you stick it in the hole and it reads 22, then what.? 22 what?

Good question. Its not a drill size and its not Metric.

Try these ...

Metric system chart ... you'll find your 22 listed.
http://mdmetric.com/tech/tic1d.htm

Wikipedia history of the metric system.
http://en.wikipedia.org/wiki/Metric_system


I'm still a little confused about ...

1. The items age?
2. If old, why metric?
3. Did our dad's, uncles and grandpa's use metric?

*Note: I am 'assuming' it was made for the American market - pre-1970 :dontknow:

I dont think its Metric Bob. Note that 3/4 inch does not equal 48mm. http://mdmetric.com/tech/cvtcht.htm

Big Cy ~

I see where your're coming from and totally agree to a point ... which means I agree about the upper portion where the 48 and 3/4 are. But I am not totally convinced that the lower numbers are not metric. Please note that I am being completely open minded here and will accept the chips where they fall!

Here's a link to a metric conversion site. All you have to do is pick a number like the 22 and measure the width at that point. And then enter the 22 in the easy to use conversion box on the site and see what you come up with. You can also experiment with some of the other numbers. I tried to guesstimate some of them myself, but your pictures are slightly larger than actual size and throws things off.

Please let us know the results of your experiments. If it is not metric, then it opens up a whole new can of worms.

Thanks.

The numbers are 64ths. 40/64=5/8 ,48/64=3/4.

Round hole screens are often designated by a single number such as 10. This means the screen is 10/64ths of an inch in diameter.

I would guess its for measuring screens in air screen cleaners for seeds.
