Richard perhaps you could incorporate a Gedge bit into your coat of arms?

I haven't seen one like that, but what is interesting, is the shaft with the spiral brazed on strongly resembles the Dimitt/ Irwin bit. https://patentimages.storage.googleapis ... 306907.pdf But how can that be, Holtzappfels book was written in 1846 and Dimitts patent isn't until 38 years...

In our conversation on the Gedge bit, Andy T mentioned a auger bit with a detachable cutter which was described in the 1846 reference book: Volume 2 of Holtzapffel's "Turning and Mechanical Manipulation" and asked if I had one of these bits. As it happens I do, a 5/8" branded Mathieson and the...

As is quite usual for me I dived in without looking. Prior to my previous post I should have read the attachment that Andy provided which I have now done. It would seem that John Gedge was a patent agent as stated on pages one and two. At the top of page one he says " a communication from Mr...

Andy you are an absolute legend. Thanks very much for your hard work in tracking the patent down. I haven't read the text of his patent yet but it will be interesting to compare Gedges claims with those of Cook in the USA who headed him off by three years with a bit that is more or less...

I've been trying to find the patent for the Gedges pattern auger bit but no luck so far. I have attached two photos of Gedge style bits. The two shorter bits are branded: James Swan Cook Patent USA this is a reference to Ransom Cook who patented this bit on June 17 1851 (US Pat' 8162)...

I think that's the reason Gallywood. Some are more pronounced than others, but most seem to be built that way. Cheers, Geoff.

A horror trip alright, but the fans were celebrating BEFORE the rugby matches.............well on our recent performance probably a good idea, not much to celebrate after. I remember a trip on Air NZ to NZ a few years a go and the Wallabies were playing the Lions in England and the pilot...

Oh, now I remember where we met Bob, I was your probation officer when we escorted you back onto the plane out. :D :arrow: :( Cheers, Geoff.

A couple more Cox style bits have come to light in Aus' one Ridgeway and the other Mathieson. Neither mention Cox which indicates they may be later than the Marples examples. Reading the leaflet that Andy posted from the Hawley Tool Collection on the making of an Auger I would hazard a guess...

Bob, some of us have to live at the bottom of the world, otherwise it would rotate erratically. Does this photo of a Stanley 909 illustrate your comment about the crank not being 90 degrees to the handle? This configuration of angles on the crank is more common than for all bends to be 90 deg'...

I think the side screw is a friction tensioner which gives more or less drive to the raise/lower function depending on how tight you have it. Haven't got one in front of me but I think the threaded rod that raises/lowers rides inside a tube which the friction pad contacts. My interest in this...

Hmmmm Bob let me think, (clunk, whirr) you paid 15 Euro equals about $Au25.00 + 10% markup for you + postage $Au30.00? That comes to $Au57.50. Cost to me to replace 4 x 1/8" balls that escaped out your door. Would you take 5 Euros? And I'd love to see a photo or two. Cheers, Geoff

There's nothing meaningful that I can add to this conversation, apart from, the idea of bending the frame with the handle in position was patented by Harry Bartholomew in the US in 1861 (US Pat' 32347). Thanks for the video, Andy, I always marvel that the operators of that type of machinery...

I really like the idea of a dowsing tool but I think insulated handle(s) would defeat the purpose.

Thanks Andy, some interetesting reading there.

I've got a couple of pampklets here, I think by Stanley and Irwin, on the steps in the process of making an auger and you're right, a lot of hand work involved. My first impression when I saw this auger was that the lead screw twist was simpler to make than the conventional style. Geoff.

Thanks Andy, I havn't considered either option but I do have a friend who has published a number of books on Aus' tools, perhaps I should talk to him about it. My main hurdle is not having a manufacturing background, for instance for Marples to tool up to make and brand these auger bits, what...

Buoyed by the enthusiastic response to this most interesting post I have more to add. A correspondent in the UK is unable to find any mention of Cox's patent in any Wm Marples & Sons catalogues, he has suggested they may have been a special order for the Aus' market. This would make sense that...

Ok I've found a patent from 1905 for a wood auger by an Australian Edward Cox. US Pat 778845. This patent is for an improved lead screw, to quote, "My said invention is confined, chiefly, to the tip or worm of the auger-namely, in the set or taper of the spiral thread of such tip so arranged as...
