    Help please! Unusual unknown 1800s patent model of a lathe, boring, cutting machine?

    Yes, the size limit for the model was 12", but I had much bigger examples also. My biggest was a model of 18" wide. The other models are not related. They vary in age, from 1847 to 1873, and purpose. There are different inventions here.

    Help please! Unusual unknown 1800s patent model of a lathe, boring, cutting machine?

    The patent has been granted for this invention. The patent has been granted for this invention because the ribbon was attached. That ribbon used to hold a patent tag with a number that got lost. I can find a patent, but I need to know keywords for searching.

    Help please! Unusual unknown 1800s patent model of a lathe, boring, cutting machine?

    This is a 12" by 12" patent model from Rundle Gilbert's collection of Original US Patent Models. It was discovered along with other patent models but this example just did not have a tag attached. It even has a certificate telling this is an original patent model. Nobody just knows the patent...

    Help please! Unusual unknown 1800s patent model of a lathe, boring, cutting machine?

    Great idea! Thank you! I know that key cutting machines use discs. Maybe in this early example, the inventor used different cutters. The only thing is I am not sure where the key would be secured.

    Help please! Unusual unknown 1800s patent model of a lathe, boring, cutting machine?

    It might be missing some parts, but patent models were inventions in miniatures and they were operational ones, demonstrating the invention. Wire bending? Sounds interesting. Maybe a wire twisting machine, but there are no small hooks like on the manual wire twisters the wire attaches or slides...

    Help please! Unusual unknown 1800s patent model of a lathe, boring, cutting machine?

    Interesting guess! Interesting guess! Thank you! I am not sure how exactly a valve or a pipe would fit. I see that two pulleys rotate bore-like pointy pieces against the center sharp piece that is static and does not rotate. Maybe the key would be in finding out what is placed between those bores?

    Help please! Unusual unknown 1800s patent model of a lathe, boring, cutting machine?

    Dear engineers. I need your help, please. In my collection of original American patent models, I have an interesting example of a mechanical lathe, boring, cutting machine, or tool. I am not sure what this is but I know that it is a patent model submitted to the US Patent Office in the 1800s...

    Probably the most unusual mystery tool from 1700s! What is it for?

    Me too. It is a fascinating tool that could be created for a specific task. That is why it is not easy to figure out its purpose. These days we probably use tools that are so much different than in the 1700s or, as you noticed, even earlier. Thank you for the information about the other pieces...

    Probably the most unusual mystery tool from 1700s! What is it for?

    There is no date. There is just a century. This is the tool from the 18th century determined by the museum. You do not need to know the purpose of the tool to determine what century it was made. There are ways of determining that specialists know. As for Three Stooges Museum, yes, there is one...

    Probably the most unusual mystery tool from 1700s! What is it for?

    :) That's amazing. I do not remember those times because I was probably too young, but I love to listen to Barry White's music and songs.

    Probably the most unusual mystery tool from 1700s! What is it for?

    Well MrStretch, this is not a clock. I am surprised that somebody with such out-of-this-world antiquarian horologist experience did not notice that :) Again, we are not determining the age of this tool. Please, read the question of the posting carefully. It has been determined by the museum...

    Probably the most unusual mystery tool from 1700s! What is it for?

    I am not insisting. It is a fact. Museum determined its age as an 18th-century tool. That means it was made in the 1700s. At that time they never write Made in... They would simply place a yer, but in this case the tool does not have any numbers like that. I like your guess about the weaving...

    Probably the most unusual mystery tool from 1700s! What is it for?

    Agree. It is crafted very nicely, but if you look at the laboratory tools from the 1700s, they feature even more fine details than this tool. This example made quire roughly comparing to some science piece from that era made of brass.

    Probably the most unusual mystery tool from 1700s! What is it for?

    I like your guess! I do not have any musical background in the family, but the previous owner had an idea that it could be a tool for making violins. I would guess he meant for bending thin pieces of wood used in the violin's body. That could be it. but then, violins had patterns already cut in...

    Probably the most unusual mystery tool from 1700s! What is it for?

    That is an interesting guess! Thank you! I believe the keyword here is "replication". It makes sense! First, you set the size, then place material inside the slots, then you can trace the shape to make copies. I never thought about that.

    Probably the most unusual mystery tool from 1700s! What is it for?

    Are absolutely correct Bill! The tool could be even earlier than the 1700s. And, nobody would place that amount of effort to forge a tool. I am glad you noticed many details that can point to its age and especially its purpose!

    Probably the most unusual mystery tool from 1700s! What is it for?

    Emanuel, you do not need to know the purpose of the tool to determine its age. Museums have their own practices of doing so and it is not based strictly on the use of the tool. There are many hints that point to its age. Again, we're not discussing age. We already know it. We are working on the...

    Probably the most unusual mystery tool from 1700s! What is it for?

    I do not know exactly how the museum determined the age. They must have tools with similar features or they referred to the engravings. The tool is obviously older than 70 years, so no need to write anything more. Especially when I clearly stated that the tool is from the 1700s. If I would not...

    Probably the most unusual mystery tool from 1700s! What is it for?

    Ok Bill. The arms are extended to the maximum. It appears that the middle arm extends the most for the maximum of 5". I've placed a strip of paper to each slot. This way it will be possible to see the curves. I did not extend the arms widthwise because they will just go until the end of the...

    Probably the most unusual mystery tool from 1700s! What is it for?

    Yes Bill! I will do that. Just have to come back home to get the tool. I will post new photographs soon.
