modified construction differs from the con- .1s made up of four sections, instead of being formed a continuoussheet of metal; and that instead: of forming apertures linthe wall of the casing for the passage ofthe screws 9 therethrough,fa vcontfunious'space 14 is pro- 'vided between the side edges vof adjacentsecf.l tions, so vthat there'is a resulting saving in materahand of .labor involvedA in forming "the four lines of apertures in theca'sing ofthe main construction.V The' ,cylinder asa Whole maybe rapidly assembled, and it will be ap? parent that, withthewelded units of the cas'- ing lassembled as describe'd, when the screws 9 are passed through the apertures 13V into engagementxwith the 'lugs y5,!a firm or rigid construction of cylinder is provided.v
