Webmore (Birmingham) and Company Ltd

Filed under: Makers, Screw adjust — admin @ 7:55 pm

Webmore (Birmingham) and Company Ltd were located at 10 Camp Lane, Kings Norton, Birmingham 30
They made a small cheap to make adjustable that was made of only 4 parts, the folded sheet handle a two pressed out jaws and a worm.
They obtained a patent also in the name of Ivor Richard Harris who worked at the company.

My example is marked Prov Patt which dates it to the period Dec 1947 (application date) to March 1950 when the patent was granted.

ATC or ATL adjustable spanner

This one is taking some discovering at the moment, it has the following stamped in the recess as far as I can tell.
AT C MARCH 26 1895 but it could be AT L MARCH 26 1895

Thanks to Stan I now have the design patent but it is from Design 29520 Oct 18 1898 by a Charles Metz, probably a case like another spanner I have where they were keen to manufacture but the paperwork takes too long so they just start manufacture with something such as an application date on the tool.

Mauser Adjustable Spanner (Engländer, verstellbarer Schraubenschlüssel)

I got this on Ebay, very little wear but does have some damage to the worm which after a little investigation is a basic design fault, there is a turning moment that rotates the worm out of mesh when the force is applied, this can be demonstrated with just finger force on the moving jaw.

I dont have a date yet for the spanner but I do have an English patent dated 1948 which does not mention Mauser at all but the patent is so similar to the tool that its a copy or… will someone tell me.

The Lovell Wrench Co

Filed under: Makers — admin @ 6:40 pm

They made an adjustable wrench that was supposed to be cheap and light it was patented by
Albert Kingman Lovell, May 12 1896 No 559901.

The example I have found differs in the way the worm is attached.
They failed to think too hard about where they stamped the name on the front and patent details on the back, both are on the upper jaw joggled bend.
