Railway master mechanic [microform] . tions in side weatherstripping, dust deflectors, sash balance and sash lock-ing means for car windows is manufactured by theGrip Nut Company, Old Colony building, Chicago. Fromthe illustrations and description it will be seen that one ofthe essential features is the ingenious arrangement of flexibleweather strips applied at the two sides of the window on thesash. In this construction the inside window stops and finishis placed away from the sash, and the sash is fitted loosely, allowing clearance edgewise to prevent binding. The necessary opening around the loosely fitted sash ispositively sealed, air tight and dust proof by the weatherstrip forming a flexible joint, also cushioning the sash broadside against the outside stops and at the same time central-izing the sash between the two window jambs, which notonly reduces the friction to a minimum, providing easy op-erating sash, but eliminates all rattle. This is a novel de-parture from all previous practice and is claimed to eliminate. Gravity Wedging Sash Lock, Flush Stamped Wedge Rack, Con-tinuous Cast Wedge Rack and Individual Bottomand Upper Wedge Racks. the defects which have heretofore been accepted as necessarydefects, impossible to correct. A clever device to prevent rattle and the sash from fallingis the gravity wedging lock. The lock bolt is beveled 45degrees and settles into a corresponding downward and out-ward beveled rack. A gradual wedging of the sash againstthe stops in its downward movement effects a gradual stop, preventing the usual sudden jar, which loosens the screwsand fixtures, breaking glass, etc. The sash is securely lockedagainst the outside stop in a peculiar manner, preventing allrattle and accidents by falling. Various designs of these racks are made, some of whichare shown in these cuts. The pressed rack appears espe-cially neat, as it sets flush with the stop. The designs costno more than the ordinary continuous rack. The individualstops also show
