The KenneyVacuum Sweeping System as we saw itapplied to the cleaning of cars in theyard of the Central Railroad of NewJersey was a revelation in the art ofgetting rid of dust, which makes thehard working carpet beater and thetidy housemaid look like very smallchange indeed. The plan which has been admirablyworked out by Mr. David T. Kenney,of 72 Trinity place, New York, is briefly. metal pipe with a flat triangular end,along the base of which is an openingthat is simply a slot. When the airdrawing machine, as the inventor callsthe pump, is in operation, air is drawn separators are simple in the first is the one in which mechan-ical separating takes place, and in it90 per cent, of the dust is taken fromthe air. The second cylinder draws the CLEANING CAR SEATS—KENNEY VACUUMSYSTEM. that a system of pipes is run throughthe yard with ground jointed inletroundway cocks placed at convenientpoints, and a vacuum pump with me-chanically operated valves, and stationedin the power house creates a high vac-uum, and draws air through the systemof piping which covers a distance of3,600 ft. There are in all about 3 milesof piping varying from 5 to 2 ins. in di-ameter. There are many interesting de-tails in the operation of this system, butthat much is the idea in
