Title: 2" C Clamp with Mickey Mouse Ear Thumbscrew
Post by: J.A.F.E. on October 23, 2011, 05:12:59 PM

Found these at the swap. I think they are J.H.Williams but not certain. They are pretty neat though. Can anyone confirm JHW and the time frame? I found nothing in my search of AA.

The name is very difficult to make out but it looks to me like JHW&Co.

I suspect your guess is correvt, and I suspect they predate 1918 or so. C-Clamps were one of JHW's earliest products, and they had many patterns, however, it is very hard to find pictures of certain ones. The widely advertised standard patterns have slide handles , or a hex head lead screw. The ribbed reinforcment is also not shown anywhere that I have seen (Tho armstrong used it on some of their clamps)  I also don't know what the strap clamps look like...

as of 1921, there were (advertised)
 4 patterns of regular C-clamps (which later seem to be heavy,medium,light, and ???)
 6 patterns of parralell jaw machinists clamps
 ?? patterns of strap clamps

The Diamond W logo is fairly consistant by the early 20's, but doesn't seem to appear before that..
So a plain W is not unreasonable....

1914:

I've seen the thumbscrew pattern referred to as "carriage makers clamps."  I like them, and have a variety.

Thanks rusty and Branson.

I really like that display stand - that would be a very cool item to have.

They are listed in my 1960 Williams catalog as No. 201 Vulcan Tool-Makers' "C" clamps with swivel screw.  The jaw capacity should be 3/4".

Thank you wxtools, the capacity is 3/4. I rather like these clamps and if they were made into the 60's then there's a chance I could find more so that is very good news.
