To @ZZ fio/icm it may concern;

lie itknown that We, BERT W. DA cnn ,"end Ennon E. E MsHWILLER, citizens of th illnited States/residing, respectively, at Len ning, county oi Ingham, State of Michigan,

end East Lansing, county of ngliam, State.- oi' Michigan, liave'invented. certain new and A.iseful Improvements, in Valve Structures, 'which the following is a specification,

reference being had therein to the eccompanying drawing.

rilhis invention comprises a Lvalve structure. lt is especially applicable for use in' connection with an internal combustion lenzine, end` itis contemplated to provide inechenisni which Wiil'insure proper intake ci: combustible mixture and proper exhaust er the gases a'tter the mixture has been iired in the` cylinders.' vAnother object is the elimination K of springs, cliein-andsprocket, bevel orA Worm gear connections, end nnnecessery velvememhers, which willsiniplify the inethod'of' operation, make the verts more accessible, and minimize Vilore` A stili further object of the invention is to provide e valve-structure wherein the valvenienibers are rotated around e common exis, one upon another, each being provided with intake and exhaust openings and arranged i in connected sections so that any section may easily reznoyed .and replaced, the entire structure hein@ mounted in a Valve-seat pro-v vided in the cylinder-.block in proximity to the cylinders. T is arrangement minimizes the lieliility of the Valves becoming carbonand; assures more even and positive nin addition to smoothness et' opera? ized., CL 'tiem i .i Y Other ohiects "and advantages of the inention will in part-be apparent and in part "ne hrougit out more fully in the description *which follows Anemloodiment of the invention is illustrated inthe accompanying dre-Wings, the following views y being shown:

shown in Fig. l. Here the sections are cured oy threaded connections 6, The innermost section is closed et the end either by the portion of the cylinder againstwhich it abuts or by a Wall 7, as here shown, er other suitable means. A central opening or channel extends the length oi' the member to constitute a hollow cylinder mounted for rote tion in tire cylindrical opening in the cylin der-block, the opening constituting e velveseat for the onter-nieriher.
