I’m back…with a question from a reader

August 30, 2006 on 2:10 pm | In Interesting Patents |

Sorry for the light posting…I took some vacation and have been buried in other projects.

I did receive the following question from a reader today:

I have my grandmother’s old hand-operated meat grinder.  On it is imprinted:

PAT.MCH. 4.’02.

Does this mean that it was the fourth patent issued in 1902?

I’ll appreciate any information you can provide.

My response would be:  I doubt it.  To the best of my knowledge, I don’t know how you’d even easily determine what the fourth patent issued in 1902 was, let alone would that have necessarily been information the Patent Office would have provided to a patentee.

If Buchanan is done standing in the bathroom taking pictures, maybe he (patent marking plate expert) can answer it.  Or…perhaps one of my readers can decipher the marking (the comments are open).

  1. Certainly not the 4th patent in 1902.

    Perhaps it is just March 4, 1902. A quick search of all patents in 1902 and in class 241 (SOLID MATERIAL COMMINUTION OR
    DISINTEGRATION) shows a meat grinder Patent No. 694704 patented on March 4, 1902.

    Enjoy

  2. A number of readers also E-mailed me the same thing. March 4. In retrospect it is obvious.

    Thanks to Eric for the searching.
