Dec. 6, 1949 PUMP B. BARTOLUCCI Filed June 15, 194e Z@ ZZ JNVENOR.
Patented Dec. 6, 1949 entre Nr OFFICE PUMP Benedetto Bartolucci; Chicago, Ill. Application: .lune 15:, 1946; Serial No. 676,920.`
(Cl. 10ft-114) machines,. milling, or other. similar. machines where. the. liquid .is-used.. for. cooling purposes-in.
the. operation. of -,tools andthe like.
Oneof .theobj ectsof. thepresent invention is .to
provide a very eicientfandsimpliiied vconstrucf tion. of an. industrial.. pump which.: can beV easily.` and Lquickly dismantled forthev purpose of` insert-4 ing .reliner`s andlto permit easyaccess to theopr erating.partsofV the pump.
A further. object 4of thexrinventin is* to. provide aA simple and more. eicientpumpin which the. main fslaftlofV the pump is.;supported on `one side f thereof andi thereby prevents the. necessity of re,.- I moving the bearings so that access to thepump 20,
housing.- may bee hadE without. dismantling the pump shaft.
These and otherpbjects-:arei accomplished by providing a construction and an arrangement of the l various partsin'- the manner 'hereinafter described and particularly poir'1'ted--out-'inV the appended clainwxsf.`
Referring to the drawings:
Fig.' Al'is a side elevational 'v ifew ofmy improved" pump construction;
Fig. 2'is` an enlarged' longitudinal eross:sec tlonal view"inwhicrr the parts" are diagram.- rna-tica-lly displaced for-the-purposes of showing the" manner'l inwhich the" pumphousing* isY disa assembled to permit the removing and replacing the liners thereof;
Fig. 3 is a similar cross sectional view showing the pump in assembled form; and
Fig. 4 is a fragmentary cross sectional view taken on the lines 4 4 in Fig. 3 of the drawings.
In illustrating one form of my invention, I have shown the same as comprising a main horizontal base member I on which is secured a substantially U-shaped bearing support II. Mounted on and secured to the upper surface of the arms of the bearing support I I are two spaced apart pillow block bearings I2. Journaled in suitable anti-friction bearings I3 in each of the pillow blocks I2 is a main pump shaft I4. Mounted on the main base I0 on one side of the support II in the manner well understood in the art, is an electric motor, generally indicated by the reference character I5. The electric motor I5 is provided with the usual drive shaft I6 and has one end thereof connected to the pump shaft movable dome-like section I9 and a somewhat similar stationarysection 20. Thev housing sec tion 20 has a horizontal flange portion 2| for the purpose of securing this section to ther main base I0 by means of bolts 22. Thehousing section. 20 is providedwith a sleeve-like. hub 23..-through.- whichfthe pump shaft I4- extends.- Surroundingv the'shaft I4 within the sleeve is theusual pack-- ing;24. Between certain parts of `.the packing is a packing lubricating ring 25. The packingrings are held in position by the usual adjustable pack-.-- ing gland 26; Secured tovthc'outer'end ofthe shaft I4 isa rotorfin the form of two radially pro jecting blades 21, which have their inner ends conl forming` to thesurface of `theshaft Yandclarnped'- thereto by-bolts 21. Mountedwithin and com.- plementary ton each of' the housing sections I9" and 20 are vreplaceable liners or innerpump cas-- ingfmembers- 284 andi29 respectively. The outer surface of the innerl linermember 29v is provided with concentrically arranged annular lnished anges-w 3-11 and: 32 which. areadapted to con-tact concentrically arranged annular flanges 33 yand 34 respectively of thelhousing section 25,-. sov as to impingetherebetween the respective gaskets 35 and 36. Inasimilar manner, the in ner liner member 28 is provided with concentri callyy arranged annular.A anges .-3-1 and 38': which are complementary to the annularl flanges 39k and 40 of the housing section I9 respectively, so as to impinge therebetween the respective gaskets 4I and 42. The inner liner member 28 has a relatively large central opening 43 which is in alignment with a central bore 44 in the housing section I9. Formed integrally with the housing section I9L is an elbow shaped connection 45 .which terminates in a connecting flange 46.
This elbow 45 and connection 46 forms the inlet to the axial center of the pump. The inner liner member 29 has a vertically extending conduit or tubular portion formed integrally therewith as shown at 41 which is arranged tangentially to the periphery of the member 29 and forms the outlet port as shown at 48 through which the liquid is discharged by the rotor or pump member 21. The outer surface of this discharge conduit or tubular extension 41 has complementary and embracing portions formed on the housing sections I9 and 20 as shown respectively at 49 and 50 so as to embrace the same when the complementary housing sections I9 and 20 are bolted together. Formed integrally with the respective housing members I9 and 20 are horizontal connecting iianges I and 52 for connecting suitable conduits to the discharge or outlet of the pump proper. A suitable gasket 53 is provided for the circular flanges 5I and 52 for connecting the same to a suitable conduit. The inner liner members 28 and 29 have complementary convex recesses 54 and 55 which conform substantially to the conguration of the revolving rotor or pump member 21. The liner member 28 has its inner face formed in the annular finished surface as shown at 56 which is adapted to seat on a complementary finished surface 5l on the inner liner 29 to completely encase the rotor. The housing members I9 and 20 are provided with peripheral complementary flanges 59 which are secured together by uniformly spaced apart bolts 58.
From the above decsription it will be obvious that should it be desirable to replace the inner liner members 28 and 29, which occasionally become worn, by reason of wear through the action of abrasive materials or metal shavings circulated with the liquid through the pump, all that is necessary for the operator to do is to remove the bolts 5S from the adjacent flanges 59 of each of the housing members I9 and 2|), disconnect the coupling member I'I and remove the outer housing section I9 and inner liner members 28 and 29 and the main shaft I4 with the rotor 2'I in the manner diagrammatically illustrated in Fig. 2 of the drawings, This arrangement permits easy access to the operating parts and liners of the pump. It will also be obvious that by supporting the main shaft I4 in the bearings on one side of the pump housing that considerably less effort and time is required to replace the inner liners that would ordinarily be required if the bearings had to be removed. It will also be noted that by positioning the electric motor on the other side of the bearings the whole pump structure aords a balanced power driven pump of great efficiency.
While in the above specication I have described one embodiment which my invention may assume in practice, it will, of course, be understood that modification may be made therefrom without departing from the spirit and scope of the invention as expressed in the appended claims.
What I claim as my invention and desire to secure by Letters Patent is:
1. A pump comprising a housing in the form of a relatively stationary housing section and a removable section, an inner liner casing in the form of complementary liner sections, two concentrically arranged annular nished surfaces on the outside surfaces of said liner sections complementary to corresponding finished annular surfaces on each of said housing sections, the two concentrically arranged surfaces on each side of the liner sections being located in the same verti cal plane gaskets impinged between said annular surfaces, a shaft journaled in said stationary housing section, and a rotor secured to said shaft and rotatable in said inner liner casing.
2. A pump comprising a base member, a bearing secured to said base, a pump shaft journaled in said bearing, a pump housing comprising two complementary dome-like sections, one of said sections secured to said base, the other section removably secured to said first named section, an interliner casing in the form of complementary liner sections, one of said liner sections having a discharge conduit positioned tangentially with respect thereto, two concentrically arranged annular iinished surfaces on the outside surface of each of said liner sections complementary to corresponding nished surfaces on each of the housing sections, the two concentrically arranged surfaces on each side of the liner sections being located in the same vertical plane said pump housing having a liquid inlet thereto and a liquid discharge outlet located tangent to the periphery of said inner casing, a rotor secured to said shaft within said inner casing, peripheral flanges formed on said housing sections, and bolts extending through said anges forsecuring said sections together whereby one housing section may be removed for replacing inner casing sections without disturbing said bearing.
