The Gibbs Respirator, while not being well known or particularly innovative, is of interest as it is a good example of what industrial safety products looked like in the 1800's. Consisting on a simple nickle-plated metal oral-nasal cup, it used a wet sponge as a filter, not unlike the earlier Hurd mask or the later H.S. Cover's automatic respirators.

The ad to the right also dates from the 1890's, albeit later in the decade. Notice that it mentions that English Physicians had been recommending similar devices for 50 years prior.
