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". |

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. |

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. |

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. |

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." |
