A Guessing Game

OK, can anyone figure out (or guess) what the little projections on the blade are for? No fair looking up the patent before making a guess here.

The lettering in the picture reminds me of a B. Kliban cartoon. He was probably copying the appearance of similar material.

Paul, that's a puzzle! I don't know how you manage to find these. :D

I found it while looking for patents for the Gillette NEW razor, came up with an assumption about the projections, then read the patent and discovered that my assumption was wrong.

My search started by reading an old thread we were both in, where we and others were trying to figure out if you had a NEW razor or a "New Improved."

I also found some Gillette SE razor patents from around the same time.

I was thinking alignment of some sort but that makes no sense. So I'm guessing they push the blade off of the bed of the razor to make it easier to grasp. Not that I ever thought that was a problem.

No, they're not for alignment while you're shaving.

They do push the blade off the bed, but the reason doesn't have to do with making it easier to grasp it.

Early leaf spring suspension for times when you take your razor off-road.

Slant razor without the slanted head?

Chris, you're right! (not)

And no, it's not to slant the blade.

I'll also eliminate my original guess - to have yet another patentable, exclusive thing to hold the blade in the razor, in addition to pins, slots, and all the other projections.

Mr. Gillette or whoever else may have owned Gillette in the 1930s probably had a department (one guy?) who was constantly developing designs fit for patent. Just as he also had a department (some other guy?) in charge of finding small companies they could either buy out or otherwise put out of business.

Do you know about the merger between Gillette and Auto Strop?

The history of the company is very interesting. Here's a good description I found: http://www.fundinguniverse.com/company- ... y-history/

Should I reveal the answer? The replies seem to have petered out.

I'll give a hint - the feature is apparently an attempt to have some new patentable feature, but it doesn't have to do with how the blade is positioned while the blade is cutting your whiskers.
