Measures to secure a patent for the above havebeen taken by James Campbell, of Ma-con, Ga. Carpenters and cabinet-makers will appreciate the advantages of this machine, which performs its work with great rapidity and correctness. It is intended to cut cross and other grooves in wood by employing an S-shaped cutter in combination with two cir cular saws, these three tools being fixed on a horizontal revolving mandrel, which can be adjusted to suit whatever depth it may be re quisite to cut the groove. The saws make the incisions and the cutter completes the re cess by removing the wood, and makes the groove square, perfectly smooth and true. The operation of grooving at different angles and widths is facilitated by indices marked on the sliding carriage, which moves transversely, and therefore teeds the stuff in that direction, but is susceptible ot alterations for feeding at any angle.
It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.
There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.
