The Mojack, which is manufactured by James Wiley and Sons, Ltd., of Darlaston, for whom the sole wholesale selling representative is G. H. Smith, 12; Mortimer Street; Lenclon, W. 1, has recently been brought out in a highly improved form. The action of the pump is quite distinct from that of any other type of jack, a semi-rotary backward and forward action of the handle or the left of the operating point to lift, and on the right to lower, being all that is necessary to operate the jack. The jack is made in six patterns, three of which are fitted with roller bearings for heavy loads
