What Does It Do?

11/28/2021 5:30 PM

We all know that this is the backside of a General N-141me.

The front just has a bunch of marks and numbers.

What is the purpose of the groove in the back?

It's a probe for measuring the depth of holes...

No it's a a pop out angle measurement tool...

Possibly conversion tables printed so small as to be useless...so maybe the slot is for a linear magnifying glass...

The letters in the groove say "MADE IN SWITZERLAND."

It is best to keep quiet and be thought a fool, than to make uneducated gueses in order to "prove" your incorrect theory guess and remove all doubt.

If you don't know, why waste our time.

Browbeating fellow posters is not in compliance with posting guidelines...will you never learn this simple rule? Your humorless offensive manner goes against everything that has just been posted in the 'Welcome Wagon' blog...If you can't read and comprehend simple rules and guidelines, what makes you think you ride such a high horse? I'd really like to know...

Well you might have said at the onset that there were no additional parts or pieces...the better the quality of the original post the better answers you get...so I find it telling that you acknowledge no fault of your own, and blame the respondents as fully to blame for incorrect answers...

I'm not convinced that is the purpose of the slot, it could be, but it could be there for other reasons as well....

Re: What Does It Do?

Had to look up what the n-141me was. Now i understand.

In my plastics background, such a slot would be introduced so that the material thickness was relatively even. This would reduce the amount of material shrinkage that could lead to distortion of the finished product such as cupping (across width) or warping (along major axis). In a properly cooled tool, such shape would also introduce good stiffness to the moulded part.

Such material reduction would also reduce the injection tool mounding cycle time significantly (Cooling cycle for the maximum material thickness) making them faster (read less costly) to manufacture.

If the material was "costly", there would be significantly more coring and material reduction done, since every 5% reduction means the 20th one is free (in terms of material).

We have a WINNER! And an excellent lesson on thremoplastic injection molding to reduce the amount of uneven pressures across the mold, when filling and packing a part!

I figured you and a couple of others knowledgeable in molding here would pick up on this. As you can see, this was true. All other responses were just wild gueses.

Nice Job!!!

Re: What Does It Do?

Thanks for the recognition.

I must admit to some prior intellectual property on this specific type of item. Where I worked we had literally tons of third or fourth cycle reprocessed plastic raw material that was not able to be introduced into finished product. We developed some items to utilise that material, but even then it only made a small dent in the stockpile.

One of those items was a slide vernier, but the tool design meant that only one material was suitable due to shrinkage.

At one stage we had nearly 100T on hand.

We borrowed demonstration tooling for "airfix" style toys that included dinosaurs, zoo animals and so on. The beauty of this was that each part was of the same material and thus shrinkage was well matched within each kit, even though parts from alternate materials could be as much as 10% different in absolute length/height.

PC, POM, ABS, PVC and so on with up to 75% fillers ranging from talc to glass.

We developed a tote bin that used around 2kg per shot. 20,000 bins were made during "spare" machine time. That was a mistake. The different bins did not nest as required, jammed when stacked and so on. Eventually sold to staff for a notional cost.

I would be interested to know the reason why that lower portion (jaw side) of the grooved part is wider than the upper portion. Is it for strength, or comfort of use, or to accommodate the lettering, or to ensure a good quality moulding, or . . . ?

Only asking for my own education as my instinct would be to save material by reducing the lower portion rather than adding a groove to compensate.

I didn't design it but, my guess is to accomodate the jaws of the device on one side. Or perhaps, for rigidity. It might be that the key ring hole needed it

Honestly, with no ability measure anything but I.D and O.D. and thickness, it isn't very useful.

Being a basically typical lazy Aussie ... wait for it ... I Googled it and guess what? n-141 yielded "About 288,000 results (0.71 seconds) "

https://generaltools.com/3-in-plastic-slide-caliper

https://www.ebay.com/p/691420273

or if you'd prefer typical lazy cheapskate Aussie

https://www.amazon.com/General-Tools-141ME-Pocket-Caliper/dp/B00004T7UH

so wold most humbly suggest that said pic is a part of the General 3" n-141 plastic slide caliper.

So onward an upward - have a perfectly plausible plonk requires attention.

The groove on the back might be there to keep your pencil from rolling off while you are doing calculations or writing down your measurements,or to keep it handy while you measure.Just guessing...

The groove is .108x.108x3.75 inches.

Hardly large enough for a pencil.

No it isn't,but it allows you to use one hand to hold the caliper and the pencil together.Still guessing----

The front side shows the answer. The groove removes unneccessary material. All about saving money and providing dimensional stability.

For a quick and simple measurement of bolts or shafts of unknown diameter,I use an adjustable wrench closed up on the shaft,and then measure the gap with a pocket steel tape.Not perfect,but will give an approximate measurement good for identifying shaft and nut sizes.An old fashioned Rednek caliper.

Being the tight wad that I am,I scribed marks on my wrenches with an engraving tool. Not as accurate as the one shown,but good enough to distinguish standard size from metric bolts,nuts,shafts. I have marks for common sizes of bolts,nuts,etc.

Strange that the "front view" from the General Tools website does not show the through hole.
