. Railway and locomotive engineering : a practical journal of railway motive power and rolling stock . Car Door New Application of Mechanical Motion—Door Moved to Position by Hand. Made a Flush Door by Mechanical Action—Tight and Always Under Inward Pressure When Closed—Becomes Practically Part of the Car Side. Action and reaction are equal and op-posite. This is Newtons third law ofmotion and it has a very practical applica-tion in combination with the simplemechanism which makes the Veco cardoor a tight (lush door, applicable to boxcars and to refrigerator cars. This doorruns and its weight is carried on a bot-tom rail, formed by a bar of flat steel,which is amply supported so as to pre- a small roller to facilitate the movementof the door to and from the door open-ing. These side rods are placed, one ateach side of the door and parallel withits vertical edges. A steel rod (knownas a ciinnccting rod) is placed parallelwith the bottom rail so as to co-act withthe malleable housing (in which the smallrollers work) and which so operate thatupon closing the door, the side rods ap-.

Two upright square steel bars (knownas side rods), with malleable castings(known as guides) arc placed at the top,near the top corners of the door so as to proach each other to the extent of about3 ins., which distance can be increased ordecreased and thereby govern the pressureagainst the door through the hinges, asmay be required. Likewise they recedefrom one another upon opening the very simple opposing motion is pro-duced by the operation of a bclI-cranklever (known as the operating lever) lo- the connecting rod. This is the only ex-ample that wc know of, where opposingmotion or the to and from movementof a pair of rods, maintaining theirparallelism, closes an
