Carpenter . nventor of a new machine designedfor cleaning and finishing floors and flatsurfaces of any material. The device hasbeen patented and it is a clever andeffective invention. In his shop in Albany Mr. Kelly showstwo parts of the floor, before and after usingthe machine. In the first condition the flooris what might be expected in an old factorybuilding, while in the second it is as smoothand level as the finest ballroom. It is When it is realized that the peripheryspeed of this disk is something like 5,654feet, or over a mile a minute, the eflSciencyof the machine becomes evident. In addition to the sandpaper surfacewhich is attached to the disk, there are ar-rangements for inserting scraping knives,brushes, boring bits and tools of all sorts,so that it will be possible to fijiish all sortsof floors with this machine alone. In the Albany Historical Society buildinga year ago the first model of the machinewas demonstrated most satisfactorily infinishing the parquet floors in the rooms and. I impossible to lell by touching it which waythe grain runs. The machine consists of a cast iron disk,suspended in front of a four-wheel truck,on which is mounted a half horse-powermotor, the armature of which is connectedby a bevel gear to the perpendicular shaftof the disk, revolving it at a speed of 1,200revolutions per minute. The disk is eighteeninches in diameter, and its normal pressureon the floor or surface is about fifty-fourpounds. There is a handle to push themachine and a resistance box to control themotor. the composition in the hallways. As thedisk is well forward of the wheels of thetruck, and extends well beyond the sides, itis easy to work the machine close to a wallor baseboard. The device works so light andeasy that a child can operate it. Brother Kelly is also the inventor ofnumerous other devices which have foundfavor with the craft, particularly his well-known dumb-waiter and elevator. He is preparing to place his floor finish-ing machine on the mark
