The Washoe Tool Manufacturing Company is reputed to have started in Newburgh, New York around 1860. Sparse and conflicting information indicates that the date could have been anywhere between 1860 and 1868. In 1868 the company was using the name Old Washoe Tool Works. That terminology may have related to the actual plant or facility that was being used or it may have been a name used by different owners.
The company relocated to Newark, New Jersey in 1871 or 1872 but they were there for only a couple of years. In 1874 they relocated again, this time to Staten Island, New York. Their catalog of 1874 indicated that Hogan, Clark & Sleeper of Boston, Massachusetts were the sole agents for the product lines produced by the Washoe Tool Co.
On October 24, 1876 a company by the name of Lathrop & Co. was issued a registration for the brand name WASHOE. Lathrop & Co. were located in Newark, New Jersey and indicated the brand applied to railroad, mining, contractors, carpenters and other edge tools. The Trade Mark Registration was signed by Stephen Park Lathrop. It is presumed that there was a connection between the Washoe Tool Co. and Lathrop & Co. Perhaps Lathrop & Co. were the new agents or they purchased the Washoe Tool Co. to fulfill the high demands they had for the type tools Washoe was making.
According to a statement printed in the 1889 supplement to the 1888 Fayette R. Plumb Catalog, the Washoe Tool Co. was purchased by Fayette R. Plumb in the later part 1888 so that The Plumb Company could expand their capacity for manufacturing adzes and picks. It is not known if the facility in Staten Island continued to produce tools but Plumb did state that he had ... "erected new shops and improved the equipment." Indications suggest the new shops were in Frankfurt, Pennsylvania and the equipment was relocated to that facility from Staten Island.
In addition to some axes the company made other forged tools including scythes. Their primary lines of goods included various designs of picks, mattocks, grub hoes and striking hammers. The label that was associated with the company bore the rather detailed image of a rhinoceros standing in grass. The words TRADE MARK were included in an arc toward the upper portion of the label. Remnants of original paper labels indicate that the original color of the labels was brick red with black lines.
