`Tourlljwhonzz'li'raag/ concern: .Be 1t .known that` I, JOSEPH BERG, La citil zen `of fthe United States, 'andresident lof Little Rock, inthe "county of Pulaski and `State of` Arkansas, have invented :certain new and `useful ImprovementsinGasEngine Starters, of which the `i'ol'lolWing is a speciiication.

This invention relates 'to devices der inanually starting fgaswengines, and fhas for its object Ato `provide improved `ineansdor safeguardingi the operator uin case of back lining.

. `It `iswthe aim `cnf this invention.Ato.nialre the automatic `releasing `mechanism as com- A pact as possible and `to protect it Ifrom dust and tampering, as Well as insure its reliable operation. .1 n i i Another object isfto provide :improved and `simplified means for ioclingthe starter so that it can 'not be used to turngonerfth engine by unauthorized*persons.` v `Other obj ects; Willi Fappear as the ldescription proceeds. i i A The invention Will lirst` be hereinaiter`` described in connection with thezaccompanying drawings, which constitute part of @this specification, and then more specifically .delined in the claims at the` end.` 0f the -description.
