sterling by characters to the rawings, 1 represents a casing having an electric ries a fan constituting a vacuum producer. The fan is mounted in a spirally formed housing 1, the same constituting part of the casing and is 'orovidcd with a centrally arranged suction nozzle 5 and tangentially disposed discharge nozzle 6. The electric motor is connected to a suitable source of energy by feed wires A under control of a switch B, which switch is secured to ends of branehwires and is adapted to swing in apositlon conveniently accessible to the hand of an operator, whereby it can be nianipulated. "The casing l is secured to a nietallic spider '7 by means of bolts 8. which bolts pass through apertures in the head of said spider and are surrounded by interposed. buttons 8 that are formed from some yieldable insulating material- The feet of the spider are permanently secured to transverse flat strips 9, 9, that constitute members of a shoulder saddle G, the some being provided with longitudinal flat strips 10, 1 0, and a similar bottom connecting strip and carry, a suitable pad 12 that is adapted to. rest against the back and shoulders of the operator.
