August 23, 1918. THE COLLIERY GUARDIAN. [supplement PAGE III.] 407 u PHOTOGRAPH OF “CLIPTUB.” in the foreground are the Plates and Clips for one Complete Tub. Patent Dust-proof Colliery Steel Tub “CLIPTUB.” The “CLIPTUB” takes its name from a unique feature in its construc- tion, i.e., the Clips that hold together the interchangeable sides and bottom of the tub. The above illustration shows the ingenuity and simplicity of this invention. The Clips are of great strength and rigidity to stand the heavy strain of daily wear. The “ Cliptub ” is economical ; a damaged plate can be easily replaced by withdrawing the clips. The plates and clips may be used over and over again. The “ Cliptub ” is rivetless, therefore there is no damage done to plates when executing repairs as is the case with riveted tubs. The “ Cliptub ” is unequalled for strength, durability and upkeep.
