Butler Draw Butler Drawbar AttachmentCompany of Cleveland, Ohio, have is-sued a beautifully ilUistratcd catalogueof their attachments. It is hardly nec-essary to minutely describe this well-known mechanism for use on railroadcars. The essential feature of the But-ler attachments are the double tandemsprings, applied with what may be 1867 which combined the idea of ab-sorbing shocks not only by the initialspring resistance, but also by the fric-tional resistance produced by themovement of yielding wedges. LaterMr. \V. M. Piper emploj-ed a similarplan, and the Butler Company havingacquired the Piper patents, presents afriction draw gear in which the ideasof these pioneer inventors is BUTLER DRAW GEcalled the telescoping idea. With thisarrangement the compression of thesprings is accomplished always in astraight line and without reference tothe angle which the drawbar may hap-pen to occupy with reference to thesprings. The strain on the yoke withthis arrangement is tensile only, andonly comes into play when the car is AR ATTACHMENT. though with a range of design suitable to all modern requirements. It is possible with suitable equip-ment to absorb 200,000 lbs. pressure inone inch of travel of the drawbar. Thisis equal to a complete absorption of16,666 foot-pounds of energy. This ap-plies to severe shocks, but the design offriction draw gear which the Butler
