Description: |
| This can be considered the first commercially produced pump. This pump "may be conveniently adapted to any part of a dwelling or other place where the room is cramped, also so that the lower box or valve may be got at with much less difficulty than in the old and ordinary way, and in having the stand to which the brake is attached permanently secured by set screws uniting with a stirrup beneath a projection in the cylinder, and also the manner of securing the lower valve in its place..." |
