Each ofthese brakes consists of two smootlicircular cast iron discs, keyed to thesupporting wheel axle. On each sideof each one of these discs is a thin,copper diaphragm, held at its periph-ery, and also at its inner edge to ahousing which does not revolve andhas its bearings upon the hubs of the.

The station-ary housing is so designed that whenit is filled with water under pressuretlie copper discs are forced against therevolving discs, thus creating is made for securing con-tinuous and uniform lubrication of thesurfaces of these revolving discs, andwater is caused to flow through thehousing in order to carry away theheat generated. The water thus per-forms two functions: First, in supply-ing pressure to cause the friction, andsecond, in carrying away the heat gen-erated by the friction. Each brake is connected with thesource of water supply by a flexiblehose. It is also connected with the dis-charge pipes by another flexible discharge pipes for all the brakesempty into an iron trough and eachpipe is provided with a valve locatedadjacent to the valve in the supply pipefor the same brake.
