Patent Number Date Title Name City Description
33,751 Nov. 19, 1861 Improvement in oilers Leverett Homer Olmsted Stamford, CT The invention is an oil can with a hemispherical bottom that has no seam submerged i oil and that will tend to stay upright when set down. The cover flexes to pressurize the oil and thus expel a drop or two. An example has been seen, marked "L. H. Olmsted's pat. Nov. 19, 61".
37,971 Mar. 24, 1863 Ratchet brace Leverett Homer Olmsted Yonkers, NY The 1864-12-03 Scientific American contains an illustrated article on this invention: "This ratchet drill is the most novel one we have ever seen. It is self feeding, and has the details of the ratchet portion arranged in a very ingenious and durable manner..." The article concludes by mentioning that is was being manufactured by Davenport & Betts of Stamford, Conn., which is a bit surprising since the inventor was manufacturing oil cans and other products.
42,593 May. 03, 1864 Improvement in oil-cans Leverett Homer Olmsted Newark, NJ Raised ring or collar on oiler tube to provide a place for the fingers to push against when expelling a drop of oil.
47,446 Apr. 25, 1865 Improved ratchet-brace Leverett Homer Olmsted Newark, NJ The inventor's earlier patent ratchet brace (see patent 37,971) was manufactured by Davenport & Betts but we have no information on who, if anyone, manufactured this brace. Witness Lysander Wright was a well-known manufacturer of woodworking machinery and it appears that Olmsted was working out of Wright's shop; see also patent 47,777.
47,561 May. 02, 1865 Improved lubricator Leverett Homer Olmsted Newark, NJ The invention is a hollow shaft with a small hole drilled at each pulley location, the hole being covered by a piece of leather that allows the lubricant to slowly wick out.

54,394 May. 01, 1866 Improvement in oilers Leverett Homer Olmsted Stamford, CT The invention is an oil can where an internal tube limits the travel of the flexible top or bottom (however the oil can is constructed) to prevent the flexible part from bending beyond its elastic limit and taking a "set". The 1866-10-27 Scientific American, page 286, had a brief illustrated article on the invention. The article does not indicate whether the oil can was being manufactured. However an ad in the Classified Ads section for "Oilers—Olmsted's Improved Spring Top", from L. H. Olmsted, Stamford, Conn., was selling them in No. 1 ("Machinist's) size at $3.65 per dozen in tin.
54,760 May. 15, 1866 Improvement in chucks Leverett Homer Olmsted Stamford, CT Three-jaw chuck whose jaws are held open by springs. The shell's tapered interior prevents the jaws from closing completely, thereby avoiding their falling inside the bore of the spindle. The 1866-07-07 Scientific American had a Classified Ad from L. H. Olmsted of Stamford, Conn., for "Drill Chucks. Olmsted's Patent. Self-centering and Tightening, made from the best Cast Steel, and every piece is hardened. We make two sizes... Price: No. 1, $7; No. 2, $5.50."

84,505 Dec. 01, 1868 Improvement in paper-files Leverett Homer Olmsted Brooklyn, NY The 1877-03-09 American Artisan had a short illustrated article on this invention.

Olmsted's improved / BILL FILE / Patented December 1st, 1868".
