This invention rel,,ttes to coiiveyers, and is ,tn iiuprovement over the conveyer disclosed iii the pttent to All-en E. Crady, Patent No. 1,74'-,616 o,r,,tned December 31, 1929, C) In t@l-ie l@and@i.ng of packages qnd the like b-y of conveyers, it freqliently is desii-ab'le to provide a 1-nov,,tble conveyer section by meaiis o' -",Iiieh art'cles may be trinsL f ort-ed betiieen a inain fixed conveyer and a pl@iirality of braiieh convevers. In order to accomplish this result, it is necessary to proi,ide a conveyer see-@ion havino, one end co@nnected to the fixed conveyer anct its opposite eiid a(laptecl to siving iiito alinement with Ir) eitlier of ,t pltirality of braneh conveyers, and in devices of t@iis character, coiisiderable trou-: ble has been experienced in providing an efficient connection between the main conveyei. and the mov,,tble section to permit arti2.0 oles to p,,tss from one to the otlier.
