• Hi all and welcome to TheWoodHaven2 brought into the 21st Century, kicking and screaming! We all have Alasdair to thank for the vast bulk of the heavy lifting to get us here, no more so than me because he's taken away a huge burden of responsibility from my shoulders and brought us to this new shiny home, with all your previous content (hopefully) still intact! Please peruse and feed back. There is still plenty to do, like changing the colour scheme, adding the banner graphic, tweaking the odd setting here and there so I have added a new thread in the 'Technical Issues, Bugs and Feature Requests' forum for you to add any issues you find, any missing settings or just anything you'd like to see added/removed from the feature set that Xenforo offers. We will get to everything over the coming weeks so please be patient, but add anything at all to the thread I mention above and we promise to get to them over the next few days/weeks/months. In the meantime, please enjoy!

Can anyone point me to where I can search British patents?

I have an engineer's (?) square I obtained a fair few years ago and I thought I'd try to find out some more about it.
It has 'Made in England' and 'Pat. No. 497450' on it but I can't find any reference to it and assume I'm looking in the wrong place.
I was hoping to get some info on how it was intended to be used.

TIA

Snap! This has been in my tool box for so long I can’t remember how I got it or where from. I can’t remember using it for any purpose. Although it has some obvious functions - setting out dovetails etc
Sorry that I can’t answer your query,

Does this link work for you?

In the top-right corner there are three dots. Click on those, then click Download, then click "Original Document"

I guess the most relevant bit of the patent text is this bit:

When the tool is required to be used as a square the arm may be folded to an unobstructive position against one side of the part to which it is attached. For use as a bevel gauge the arm is swung out and secured at any desired angle. For use as a depth or height gauge the arm is adjusted relatively to the blade or base so as to bring its pointed end to the desired position. The pointed end of the arm can also be used as a scriber in the marking-off of work-pieces. Further, by providing a hole in the arm through which the point of a pencil or scribing style can be inserted the tool may also be used for scribing a line parallel with one edge or side of a work piece. Moreover the tool may be used as a calliper for obtaining a measure of the diameter of cylindrical objects by placing the object in the right angle of the square and adjusting the point of the arm to make contact with one side of the object.

Ah ha! I knew that there must be some way of seeing them but I just couldn't find it. Many thanks for that.
:obscene-drinkingcheers:

Very interesting reading that document.
First thing that stuck me was the pointy end is for scribing a line. I always did wonder.
Second was how to use it as a bevel gauge.
Then using it as a depth/height gauge. I would never have guessed.
Apparently there are 120 ways of using it, not sure what they could possibly be.

I was wondering about passing it on but I think I'll keep it now and think of old Harry Millward each time. I wonder if he made much money out of his invention.

Dovetails, one of the 120 uses I would say. :)

I was wondering if the nut and bolt on mine are original, I think mine may be similar to yours so I think probably.

Edited to say, no, I take that back. Your nut looks nicer than mine. I think mine must have been a replacement.
 
I'll just add that the apparently undersized bolt and wingnut are also found on Tom Warrington's one of these (in the "Warrington Chest") and on my own. I reckon they are original.

I’m not certain but I think it might be the item on the bottom right of this photo priced at 1 shilling and 10 pence, what do you think?
It will be interesting to see if the patent gives any clues.
The photo is from the FW Woolworth museum.

Interesting photo, thanks for posting it. I wonder how those prices compared to the average weekly wage then.

How many of the 120 uses the patent mentions have you found for them?

Not that many.

If only you could find a horse with a stone in its hoof !
To be topical, I suspect it would work well as a plane screwdriver :eusa-think:
