contact with the pump casing only. alongthe summits of said ribs.
The object of the invention istoenablethe elements to be easily withdrawn from and inserted in the pump casing and to prevent them rusting in.l
The invention is represented in the accompanying drawing which is a vertical section of the improved pump.
In said drawing g indicates the'pump casing d an end casing cover and t', 'i' the stationary rings or elements provided with extensions or risers s, s for making a close fit between them.v p
The longitudinal ribs r, r and r may be arranged on the internal wall of the casing or on the surfaces ofthe rings i, i', of each element so that either the said ringsurfaces rest on the ribs integral with the pump casing or the ribs integral with the rings contact with thewall of the pump casing, which remains smooth. v
The arrangement of acings described has the great not come into contact with-the wall of the pump casing and thus do not adhere to the latter owing to rust or dirt.
By means of the cover d the elements are held toi gether and forced against. flange a on the wall of the casing and at the same time the water under pressure forces the parts together and thus automaticallyeiiects a closer fitting of the elements.
What I claim as my invention and desire to secure by Letters Patent of the United States is A muitiple step rotary pump comprising a casing, a series of annular elements closely tting together and mounted' therein and longitudinal ribs betweenfsaid elements and casing for preventing contact of adjacent surfaces of said elements and the pump icasing except at a small number ot points for the purpose set forth.
In witness whereof I have signed this specification in the presence of two witnesses.
