What is this drawing office thing?
« on: June 28, 2020, 10:47:16 pm »


Sorry for the crap phone pic.

I've just found this in one of the many boxes of tqt left to me by my Dad. His early working life was in a drawing office. At first glance it looks like a normal pair of compasses, but they don't open in the usual fashion. A very small amount of movement is possible by screwing in the thumb wheel halfway along the body of the gadget. I think the knurled wheel on the upper part is meant to grip the spike when tightened down fully.

Yup, a compass for small diameter circles of accurate dimensions.

Pump compass, for a adjustable ink nib. pencil lead.
As LWaB says - small diameter circles only. I have one somewhere.

You know when you empty the washing machine and the number of socks retrieved is n-1, where n=the original number of socks?  It's to try and stop that.

It's got a graphite nib

Crossposts - I had to brighten the image cos I couldn't see properly.
ETA - Some of them (my one) had the option of being fitted with adjustable (for weight of line) ink nib, or pencil lead/graphite holder.
I now need to dim this display as it is hurting my eyes.

Ah, got it, thanks.  I've also got a Rulalipse, which is a Thing For Drawing Ellipses. Going by the making inside the box, he paid thirty seven and six for it.

Other than using templates, you be hard pushed to draw accurate ellipses without one of those.
They're almost getting into Spirograph territory, in how they work.

What’s a sock anchor?

I'm guessing it's not one of those underwater windsock things, for making boats stick to the water, instead of being blown around by the wind.
Careful, Kim. Your sarcasm's showing...

That's a sea anchor.

Good guess but no. My extensive nautical knowledge (I've read all the Arthur Ransome books) suggests those are sea anchors.
A sock anchor is a permeable sock around 300mm long and 50mm or so diameter fitted around a stainless steel rod. Stainless steel or plastic end caps. There's a hole in one end. Drill a hole in your crumbling wall, insert sock anchor and pump cementitious grout into it. This stick like shit unto a blanket and serve to tie the wall back together.

I think my first explanation sounded more fun.

Don't know that one in particular, but I've designed earth (and rock) anchors to tension structures against the ground, like a pile wall to support the sides of a deep excavation - you can tie the wall back by installing an anchor behind and pulling the wall back with a steel cable to the anchor.

I would have put money on this being the case.

The problem with the n-1 solution is that it will deprive L-space of a sock supply and dire consequences will ensue.

Ooh, we may have bumped into each other in Real Life.  Mrs. P*, they're lumps of metal (cast iron, stainless steel or aluminium alloy) with a hole in one end and a point on the other. As andytheflyer says a wire rope or steel bar tendon is attached to the m iddle of the anchor. Put a drive bar into the hole in the end and wallop them into the ground. Pull out drive bar, pull on tendon and the anchor flips in the ground so you can tie, eg, sheet pile walls in place.  Like a toggle bolt for he ground. Vulcan is the brand my employer makes, so named because the big ones have a (slight) resemblance to a Vulcan bomber.
