The whole thing consists of an old8-inch air-cylinder secured to a post, andtwo levers pivoted in castings fastened tothe floor. The levers have a grooved Curious Method of Compressing Air. There is a curiosity to be seen at Magog,a village near Montreal, Canada, wherethe machinery of cotton mills is drivenby compressed air obtained in an oddway. A stream of running water is usedto do the compressing of the air, and thesurprising feature of this arrangement isthat no machinery whatever is employedin doing the compressing. It is done by a singular application ofthe principle of induced currents; therunning water falls into a deep shaft, anda variety of small air pipes are led downfrom above into the falling current ofwater. The water naturally sucks in theair, which is mixed with the falling the bottom of the shaft is a cone similarto the cones used in diamond smoke-stacks. The water falls on this and is. roller at their upper ends, in which thepipe is laid in the bending process, andthe former are adjustable to any angle ina vertical plane, by means of a pair of tie-bars, which secure them in any position,with the rollers near to or remote fromeach other; the levers passing through thefloor, and are raised or lowered at willto meet the varying conditions of bendingpipes to different radii. Here is a solution of the pipe-bendingproblem in its simplest form; the machineembracing so few parts, and the degree ofroughness at which these parts can beput up. makes the cost an item that shouldnot have serious consideration by thosewho have an air plant and want a goodmachine to do pipe-bending. ft ft ft Two improvements on car seats havebeen patented by Mr. Henry S.
