actually on topic - an interesting C clamp - anyone else seen one?
I picked up an interesting C clamp today, on one side of the main casting it
says GRAND DualGrip REG US PAT OFF, on the other side it says 40A and 40 (presumably casting numbers), and QUIKCET Pat Pend. max opening is 4 inches. The copper colored parts were probably nickle plated, I polished them and there is a little silver still visible. to operate, squeeze, slide the clamp bar down, release (spring force pushes it together) and tighten the screw. to release, loosen screw and rotate clamp bar 90 deg to disengage ratchet. I tried to post to the dropbox but it seems that the metalworking.com site is inoperative right now - and I always go there first to get the address du jour. so meanwhile - anyone recognize it from the above description? I can't find anything on line about it, the company, or anything - the heavy copper plating with nickel suggests to me that it's probably pre WWII, but that's all I've got to go on if you would like a photo, get my email from my web site (below) and send me a request and I'll send you the photo I was intending to put into the drop box -- Bill - www.wbnoble.com |

wouldn't you know it - as soon as I whine about the site being down, it's
up - so the photo of the odd c-clamp is posted (see below) - the file name is: "Quikcet - Grand DualGrip C-clamp.JPG" - it should be in the drop box about the time this note makes it to the NG "Bill Noble" wrote in message ...

Hey Bill,
Thanks for persevering, 'cause I was lost with the written description!! Never seen one like that, but it sure looks pretty neat. I bet it does away with some of the damage caused by twisting the C frame of standard clamps too, and it places the working part in a better place for many jobs. Take care.

It used to be that displaying the list took FOREVER (maybe 30 - 45 secs), which the immediate-gratification me couldn't handle. Now it loads lickedy-split, as they used to say G. Bob |

The fact that the ratchet part was plated, but the plating was thin enough to wear away indicates it was made to look fancy but not designed to wear like a professional tool. Then there is that somewhat unnecessary spring to make it just a little more convenient. If you search on Quikcet, it seems they made a similar acting vise in the mid 50's. |

So, the SA advertisement is 1945, which I think still supports my feeling that this is pre war - the other reason I think it is pre war is that the parts that show in copper have VERY heavy copper plating with nickel over the copper - what wore away is the nickel - it's pretty soft, this is typical of stuff that is from the teens through the 30s. in fact, I may be at fault for removing the plating when I polished it - there was probably more remaining but I figured "shiny is good" - still it must be somewhat rare or one of us would have found out more - I found nothing on the company at all. But now we know that they made both a vise (from the SA advert) and a C clamp. |

But now we know that they made both a vise (from the SA advert) and a C clamp. The 1945 ad is actually a new product announcement in the "New Products and Processes" column. The patent for this vice was filed in 1945 http://tinyurl.com/26ww8db , so the vise was probably not produced before the war. So the question is which came first, the clamp or the vise? Grand Specialties (maker of the Quikcet vise) also has a design patent for a ratcheting C-clamp from 1945 but it lacks the extra tightening screw and hinge: http://tinyurl.com/2dhakoz . The fact it is a design patent means they probably actually manufactured something that looked just like that. The same inventor has a utility patent from 1943 for a ratcheting C-clamp with with hinge, but a lever instead of the additional screw, and no spring: http://tinyurl.com/247lcl5. This makes me think that your C-clamp with all its refinements came a little later. The same inventor who filed patent # 3147003 in 1961 also had a slightly earlier version http://tinyurl.com/2dsgxqj that looks even more like your clamp. It was assigned to another individual, so someone must have bought it. Too bad I am not patenting a clamp. I have already done all the searching. |
