Be t known that I, ERNEsr ilVILLIeiW- s0N,'t subj.ect of'Great Britain, residing at Melbourne, Australia, have invented new anduseful' Improvements inSpring Lifts for Stoopers,-"of which the followlng s a specificationn Y This inventionrela'tes to a spring'li-ftor. balancede'vice which when worn by laborers and other persons whose work necessitates their repeated bending over or's'too'ping-,will" relieve'thestrain on the muscles exercised in bendingover, 'stooping and raising the bod-y to erect position and assist in the raising ofthe-bodyyallyto the end that 'the wearer ma'y'work with greater rapiditm'ease, comfort, and accomplishmentwithouttiring so quickly as ordinarily.
An object of the invention isto provide a device of the character described, Whichis constructed so-thatthe wearer assumes a sitting position in' comfort without J neces-' sitati'ng removing the device; j 1
TheinVentioii possesses other advantages and features, soine' of which; with the forehave-selected for illustration in the draw in'gs-faccompanying and forminga pa'rt' of the present specification.
