The Shaw brake-slack adjuster is one•of the adjusters patented during the pastyear, and exhibited at the conventions ofthe Air-Brake Men and Master CarBuilders. A pamphlet recently issued by themanufacturers of the adjuster, tells us thatthe Shaw adjuster is bolted tothe guard-timber of the passenger truck, and to thebolster of the freight truck. It is con- CONDUCTED BY P. M. NELLIS. Southern Pacific Air-Brake Circular. The following air-brake circular, underdate of May 15, 1898, has been issuedfrom the general managers office:Foreign Cars—Air Brakes : Piping.

The operation of the Shaw brake-slack adjuster is as follows: When thebrakes are applied, lever A will move tothe position of dotted lines in Figs. 2 and3. As the shoes wear, the stroke of leverA will carry forward the actuating frameB until actuating pawl E advances a notchin the ratchet wheel. When this takesplace, and the brakes are released, theactuating frame is carried backward, theactuating pawl revolves the ratchet wheeland drum, and the retaining pawl F takesup a notch; by which means the deadfever is drawn over by the chain whichwinds around the drum, thus taking upthe slack. To apply new shoes, raise the pawlsfrom the ratchet wheel by pulli
