ROTARY PUMP.
Application filed `October 12, 1925. Serial No. 62,138.
This invention relates to improvements in pumps and more particularly to rotary pumps of that character lindrical housing, having inlet and equipped with a the replace parts or any part that might b or damaced.
A stili further object resides of radially extending blades operates to draw in and forcibly disembodying a cyoutlet conimpeller this invenf this chara pump embodying parte that are subwhich need from time to time to be replaced, and wherein provision has been made for ment of all ecome worn in the provision of a rotary pump that is reversible in its operation.
ln accomplishing these and other objects of the invention, proved details of construction,
I have provided the imtlie preferred forms of which are illustrated in the accompanying drawings, wherein- Figure 1 is a vertical section of a pump embodied by the present invention, the View being taken in a plane perpendicular to the axis of the rotor.
Figure 2 is a vertical section taken on the line 2-2 in Figure 1.
Figure 3 is a perspective view removed from the housino'.
of the rotor Referring more in detail to the drawingFd 1 designates the pump housing substantially of cylindrical forni, and closed at its opposite plurality of at the top oi? bolts, or the like,
ends by plates 2-2 secured lby a 3. Provided the housing in spaced apart relation is an inlet l and an outlet 5 to which suitable pipe connections, (5, may be made.
Extending through the face as designated at plates 2--2 of the housing is a rotor drive shaft 7 on which a rotor 8 isv keyed. The shaft extends through suitably packed gland vent leakage. The rotor comp s 9 to prerises a plurality of equally spaced, radially extending iinpeller blades 10 that closely tit along their side edges against the inner face s of the side walls and which are ofsuch lengththatthey will closely approach or engage with the cylindrically formed inner wall the housing, such at 11, at the top of the housing surfaces of as' that surface designated between the openings 41 and 5 and an arcuate surface at the bottom of the housing, designated at 12, which extends through an arc of ninety degrees. At opposite sides of the housing the walls are set out so as to provide for a' flow of water between the walls and endsof the impeller blades.
Formed eccentrically with respect to the rotor shaft in the inner faces of the side plates 2-2, are raceways 15 in which roller bearings 16 vare contained and on which the out-turned circular flanges 17 of wearing disks 18, that are placed against these walls, are adapted to rotate.- VThese disks have annular seats 19 formed about their periphery :lor slidably receiving therein the opposite edges of a cylindrical drum which is so disposed as to provide an open space between its lower wall and the housing but which .closes the space at the top by a close 'lit against the surface 11.
The drum coniprises four slidably joined segments, the upper and lower segments 21 and 22 having arcuate side rails 23 slidably fitted in the seats 19 and to which arcuate cover plates 2li are secured and which have transverse slots 25 therein through which the ends of opposite blades of the rotor extend. The two opposite side segments 26 and 27 are slidably supported at their edges in the seats 19 with their ends underlapping the ends of the two other segments in a iionleaking connection. rlhey also are provided with slots Jthrough which the rotor blades extend and during rotative movement of the rotor the segments move therewith rand relative to each other but maintain closed joints.
Assuming that the device is so constructed, the rotor may be driven by any suitable driving connection with the shaft 7 andas it rotates, water will be trapped between the drum and arcuate surface 12 of the housing and will be forced outwardly through outlet 5. No return or back flow is possible fer the reason that the blades are so spaced that one always closes the space between the drum and lower surface of the housing.
Having thus described my invention, what I claim as new therein and desire to secure by Lettersdatent, is:
1. A pump of the character described comprising a cylindrical casing with inlet and outlet openings, a rotor shaft extended concentrically through the casing, a rotor on the said shaft comprising a plurality of radially directed blades extended into close proximity to the casing Wall, annular Wear plates fitted rotatably to the side Walls of the casing, eccentric of the rotor, and provided with peripheral seats, a cylindrical drum litted Within the easing` and Comprising` a plurality of arcuate segniientfs each With a transverse slot through Which an iinpeller blade operatively extends7 alternately arranged segments, havingl arcuate eide rails, fitted elidably in the peripheral seats of the Wear platee and the interniediate segments having their side edges iitted elidably in said seats and l wing' their end portions reduced in Width and fitted slidably between the eide rails ot the adjacent segments.
2. puinp of the character deScribe-d comprising a cylindrical Casing With inlet and outlet openings, a rotor shaft extended ceneentrieally through the casing', a roteren the shait comprising a plurality of radially extending blades terminating` in Close prorriniity to the easing` Wall, circular raeeways formed in the opposite side Walls of the casing, eccentric to the rotor, anti-friction rollers operable in said raceways, annular Wear plates iitted rotatably to the vside Walls or" the casing each With an outturned annular flange at its inner edge, adapted for .support on said rollersv and provided, about its outer edge, With an annular seat, a eylindrical drum iitted Within the easing and comprising a plurality ot arcuate Segments each with a "transverse slot through which an iinpeller blade operatively extends, alternately arranged eegn'iente having arcuate eide rails litted slidably in the eaid peripheral seats of the Wear platee and intermediate Segmente having their eide edges i'itted eiidably in said Seats and having their end portions reduced in width and itted' slidably between the side rails of the other se niente.
