ROTARY PUMP.
Specieation of Letters Patent.
Patented-Jan. 31, 1911 Application filed May 2, 1910. Serial No. 558,794.
To all whom it may concern:
'Be 1t known that I. ALBERT E. Smm-31:, a
Chicago, county of Cook. and State of lllinois, have lin-'ented certain new and useful Improvements 1n Rotary Pumps', of which L My invention relates to improvements in rotary pumps and has for its object the proi vision `of'a rotary pump which shall be `of tion.
'lhe invention consists in the combination and arrangelm-nt of parts hereinafter de-A scribedy and claimed.
'lfheil-wention isbest understood by refering 'a part of this specitication,. and in whichf-l4 y y Figure 1 is a vertical section of a rotary pump'embodying my inventionyFig. 2, an"
the same. At the middle portion of cylinder l 2 shaft 54 is 'provided' with a spherical bearof said" shaftand provided with radial proj cting pins 7 for a purpose tofbe herein` A rotary piston member 8 is provided. with a central bearingsocket` 8 adapted to nicely fit bearing portion 7 and receive radial pins 7 to prevent turning of said piston on said shaft.
bearing surface of lportions 4 and the cyl- 80 inder walland its center located in the center of said blades. The convex edges thus imparted to blades' 1 1 lenable said blades to nicely contact with the surfaces'of bearing portions 4 and cylinder wall 2. durin their 85 travel with piston member 8in whic 1 they assume dittcrent angular positions with relation to said contactingsurfaces. ACasing 1l is provided with suitable supplyy and exhaust .openings 13, threaded for the repeption of pipes communicating withcylinder 2, on opposite sides ofthe line of contact between said'cylinder and piston member 8.
By vthe construction above Set forth, it will-be observed that upon rotation of shaft 5, and consequently piston member 8, water eef or other fluid will be taken from one ofthe form and hence capable of economical and accurate construction.- v
While I have 'illustrated `and described the preferred construction of carrying my invention into effect, this is capable of varia- Piston 8 i tion or modificati-on without departing from is secured 1n position on said bearing porl the spirit of my invention. I, therefore, do
los
not wish to be limited to the exact details of construction set forth but desire to avail inyself of such variations and modifications as come within the scope of the appended claims.
Having described (my iiivenioii what I claim as new and desire to secure by Letters y Patent is `rotary piston member and said cylinder Wall, substantially asdesc'ribed.
2. A rotary-pump comprising a cylinder; a co-axial bearing surface at one' end of said cylinder; a rotary cylindrical piston -member mounted eccentrically in said cylinder to contact with one Vwall thereof and provided 'with a radial slot; a piston blade in said slot and resting between thewvall ol.' said cylinder and said bearingsurface, the said blade having convex bearing edges lying in the arc' of a circle having the distancey between said cylinder wall and said bearing surface as a diameter; .and means for sup- 'ply and exhaust communicating with said cylinder on the opposite sidesof contact between said rotary piston memberjand said cylinder Wall, substantially^as described.
3. A rotary pump comprising' a cylinder; co-axial bearing surfaces atl either end of said`cylinder; a rotary cylindrical piston member mountedl eccentrically in said cylinder to contact with one wallthereof and provided With oppositely disposed, radial slots; piston vblades in said slots and resting between the wall of said cylinder and saidv bearing surfaces, the said blades having convex bearingedges lying in the arc of a circle having the distance between said cyllnder .wall and said bearin surface as a diameter I;-
and means for supp y and exhaust communicating with said cylinder on opposite sides Iof the contact between said rotary piston member'and said cylinder wall, substantially asA described. M y y h 4. Ina rotary pump the combination with a suitable cylinder, of a shaft rotatably mounted in said cylinder, the said shaft being proyided with a medial spherical bearing portion, the said spherical bearing poi'- tion having its center 011 the axis of said -shaft; and a Vrotary piston member mounted upon said shaft and havingagspliericahbeaiing socket fitting said shaft bearing portion, substantial] y as describedl ln testimony whereof ,I have signed my naine to this specification `in ,the presence of two subscribino' witnesses.
