“ Replying to the contention that an assignee for the benefit of creditors in Michigan may avoid unrecorded chattel mortgages, and that the rights of a trustee in bankruptcy are not less, the circuit court of appeals further said: 'As we pointed out in the Huxoll Case, the Michigan decisions mean no more than that the assignee is by the assignment given a lien upon the property which did not before exist. The mere fact that a lien is created under statutory assignment for the benefit of creditors does not give a lien under the bankruptcy act. ”

“ First, that the bankruptcy act creates a lien in favor of the creditors under which the rights given by the Michigan statute can be enforced; or, second, that the Michigan statute creates such a lien. The bankruptcy act does not operate as an attachment of the bankrupt's property, nor itself create a lien in favor of creditors of the class before us. ”

“ Payment to the bank by the bankrupt is attacked as invalid under § 9523, Michigan Compiled Laws of 1897, which provides that every chattel mortgage 'which shall not be accompanied by an immediate delivery, and followed by an actual and continued change of possession of the things mortgaged, shall be absolutely void as against the creditors of the mortgagor' unless filed for record as directed. ”
