Hall Multiplate Friction Draft Gear AFTER many experiments and tests to develop a draftgear with the maximum resistance to wear, high ca-pacity-, a moderate and positive release, sturdy in con-struction, simple to manufacture, and easily handled on ap-plication and repairs to rolling stock, the Hall Draft GearCorporation. Watervdiet, X. Y., has placed on the market theHall multiplate friction draft gear. A friction draft gear of proper design and manufactureshould meet the following conditions: The resistance towear should exceed the life of the equipment to which thedraft gear is applied. The high resistance should build. Cross Section Showing Working Parts of the Gear up uniformly without sticking and jumping so as to keep thesill stresses at a minimum for the shocks absorbed. Therelease should be moderate and positive so as not to returnmore shock than necessan,- to the rolling stock, but at thesame time insure a positive release in order that the draftgear will be ready for operation at any position of thecoupler. Sturdy construction is necessary if the draft gearis to give continuous service without repairs, as there is al-ways more or less liability of rough handling of rolling first cost should be kept down to the minimum; thislikewise applies to application and repairs. The draft gearshould be a self-contained luiit, as application is muchsimplified if there are no bothersome loose pieces. It is a well-established fact that friction tends to increaseuniformly with tlie pressure up to the point at which thesurfaces in contact begin to seize and abrasion starts. If thefriction pressure i
