Jll Moare WWW Patented Sept. 27, 1932 UNITED STATES JUDSON L. 1100311, on NEW onLnANs, LOUISIANA no'mmr rum? Application filed February 2,5,;1931. Serial" No. 518,224.
The invention relates to rotary pumps, and has for its object to provide a device of this kind comprising a casing having eccentrically mounted therein a rotor or cage cooperating with pivotally mounted vanes, mounted on a stationary shaft, axially with the cas ng and forming means whereby upon rotation of the cage, said vanes will be rotated for sucking in and discharging fluid between the vanes outside of the cage.
A further object is to provide the cage with rockably mounted bearing members 1n which the vanes are slidably mounted, and which bearing members extend transversely through the cage.
A further object is to form the rockably mounted bearing members from wedge shaped sections semi-circular in vert cal transverse cross section and to provide sprmg 0 members cooperating with the large ends of the wedge shaped members, whereby they will be moved longitudinally for taking up the wear on the vanes incident to outward and inward movement.
A further object is to provide spring actuated packing blocks between the rockable bearing sections and engaging the opposite sides of the slida-ble vanes for preventing leakage and for taking up wear on the vanes.
With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the 1nvention.
In the drawing Figure 1 is a vertical longitudinal sectional view through the pump.
Figure 2 is a vertical transverse sectional view through the pump showing the rota- 415 table cage in elevation.
Figure 3 is a transverse sectional view taken on line 33 of the cage, through one of the rockable bearing members.
Figure 4 is a perspective view of one of 50 the rockable bearing members.
members audits spring.
Figure 5 is a perspective view of one of the tapered bearing sections. ",Figure 6 is a detail perspective view of a collective kind of one of the side bearing Referring to the drawing, the numeral 1 designates a casing, and 2 the chamber therethe disc 7, axially thereof, is adrive shaft 9,
which may be driven in any suitable manner, so however a packing gland 10 is provided for preventing leakage. Formed integral with the disc 7 are concentric arcuately shaped members 11 forming substantially a drum, and which sections 11 are provided with arcuate concentric bearing surfaces 12, which taper transversely of the device for the re ception-of the tapered rockable bearing sections 13. The ends of the bearing sections 13 extendinto bearingopenings 14 in the plate 7 and the retaining ring-15 is secured to the ends of the arcuate members 11, as clearly shown in Figure 3. The bearing openings are provided with removable plates 16, which allow ready access'to the rockable bearings. Interposed between the plate 16 carriedby the disc 7 and thelarge ends of the tapered bearing sections 13 are expansive coiled springs 17, which cause the wedge shaped bearing members to move longitudinally for taking up any wear developed by the outward and inward movement of the slidable vanes 18. V
' "By referring to Figure 4, it will be noted thatthe tapered bearing members are collectively round at both ends, in vertical transverse cross section, therefore they will rock in their bearings in the chambers 14, incident to the rotation of the cage eccentricallyin relation to the chamber 2and in relation to the stationary shaft 19, on which the vanes 18 are hingedly mounted. Disposed between the ends of the rockable bearing sections 13 and within the chambers 14 are packing blocks 20, which engage the sides of the vanes 18 for taking up any wear at these points. Packing blocks 20 are forced inwardly by means of coiled springs 21,'therefore' it willbe seen that they will be held in engagement with the vanes during their longitudinal movement. Springs 17, preferably, extend into apertures 22 in the large ends of the bearing sections 13 for preventing displacement of the springs. It will be noted that a positive rocking bearing 'is rovided for the vanes, which will automatically'take lip-wear as it develops. Vanes 18 are provided with apertures 23, through which air, or fluid'will pass for preventing compression of air between adjacent vanes-and arcuate members during the rotation of the cage.
Secured to one side of the casing 1 is "a cover plate 24, in which is mounted the outer end of the shaft 19 which supports the vanes 18, and said shaft will preferably be prevented from rotation by means of a key 25. By referring to Figure 2, the position of the shaft 19, in relation to the shaft 9, is clearly shown. Retaining ring 15 is secured to'the outer ends of the arcuate cage members llby means of screw-s 26.
From the above it will be seen that a rotary pump is provided of the vane type, which is simple in construction, positive in its operation, and one whereinthe outer-' ends of-the vanes are slidably mountedin rockable tapered bearing members, formed from registering sections and cooperating with tapered bearing surfaces, said registering sections being under spring tension, whereby wear, incident to vane movement in the bearing members, will be automatically taken up.
The invention having been set forth what is claimed asnew and'useful is:
The combination with a rotary pump comprising slidable vanes slidably mounted in a cage eccentrically and rotatably-mounted in a pump casing chamber, of rockable bearing members for said vanes, said bearing members being cylindrically shaped and tapered,
said bearing members being rotatably mounted in transverse-tapered bearings ofthe icage, said bearings being formed f-romtapered segmental sections engaging opposite sides of F the vanes, springs .Within'the tapered bearings of the cage at their largeends and forcing said bearing sections longitudinally in the direction of their small ends incident to wear and packing blocks'between and spaced inwardly from adjacent ends of the bearing sections and engaging opposite sides of the vanes. v
In testimony whereof he hereunto afiixes his signature. A.
