It consists of three bodies each about4 ft. long, three of which are bolted to-length of 12 ft. and capable of taking ingether on a planer bed, making a totalsix shoes at once.

The clampsor chucks are of about the size and shape of the planer, and to which is bolted bythe usual T bolts. This body consists oftwo ribs (2) which are finished andgrooved on their top and inner surfacesto take a series of dogs (3) which can June, 1920 RAILWAY AND LOCOMOTIVE ENGINEERING 187 slide freely back and forth. These dogsare of steel with a row of case-hardenedteeth at the top. One of these is usedbetween each two adjacent shoes to beplaned and one at each end of the rowof such shoes. With the shoes and dogsin place, the whole system is drawntightly together by the bolt (4) whichruns from end to end of the whole dogs are prevented from lifting outof the body by the grooves in the sameinto which they are fitted, and the dogs,biting into the metal of the shoes, holdthem firm
