DAVIS EMERGENCY EQUIPMENT SUPPLY CO.

The Davis E&E Supply Co., Inc. is well known for creating some of the most distinctively different gas masks of the 20th century. Davis was founded by and named after Frank Rutledge Davis, a mechanical engineer from Columbia University, class of 1909. The company at first focused mostly on first aid kits, selling to both the US military and private industry.

It should be noted that Davis masks were labelled and sold as configurations, and officially the facepieces have no names, aside from part numbers. Designations for the configurations can be found at the link below.

As early as 1928, Davis (in cooperation with E.D. Bullard) was manufacturing and selling gas masks. At the time, many insurance companies required their clients to only use equipment approved by the Bureau of Mines. In order to meet these requirements, Davis filed for and received many approvals, including number BM-1408, for an ammonia mask, BM-1902, for a supplied air hose mask, BM-1911, for an acid gas and organic vapor mask, BM-1904, for a supplied air hose mask, and BM-1906, again for a supplied air hose mask. All of these kits were built using the Part Number 3020 facepiece, shown to the right.

In 1937, Davis did file their first patent for a gas mask design, and received patent number US 2,133,345 in 1938. 

The mask's design pulled heavily from the earlier KTM mask designed by the US Chemical Weapons Service in design, although it used special mix of ornage rubber and metal slide-on lens retainers. In sales brochures, this facepiece is referred to as Part Number 3020, 3040 if paired with a ten-inch hose for the M-1 configuration.

The P/N 3018 facepiece was designed specifically for the J-M mask config, and used a chin mounted filter.

The P/N 3020 facepiece was also used for the first M-27 (when sold with the hose, called the 3340) and M-O (3049) called the  configurations. To the best of our knowledge, these setups extinct. Note that the M-27 used a 27-inch hose, and the M-0 used 3 10-inch hoses joined together.

The mask to the right has an unknown heritage and origin, and currently we are unsure of when it was made, and for what purpose.

The 3020W facepiece was sold in an M-O configuration, identical to the afore-described M-O with the 3020 facepiece. However, the 3020W was never sold in an M-27 configuration, as the idea of a "heavyweight" setup with a kidney bag was largely outdated by the end of World War 2.

Sometime near the end of the 1960's, Davis apparently attempted to get a contract from the US Gov't to produce filters to protect personnel working with rocket fuel from it's dangerous fumes. Obviously this did not pan out, as the filter shown here is the only known evidence of Davis making any foray into the field of rocket fuel protection.

Thank you for viewing this info. At this time, there are no other known masks that were designed solely by Davis. However, Davis did collaborate with Welsh and Survivair, and those masks will be described in detail on those companies respective page.
