the agitator or stirrer.
Patented Aug. 3, 1943 es PATENT orrics'i 'STIRRING ASSEMBLY john Z aIiriSkie KingSport, Tenn, assignor to r .Eastman Kodak Company, Rochester, N. Y., a
"f corporation of New Jersey Application This invention relates to adjustable couplings,
Such structures are in common use in closed tanks, wherein the stirrer or agitator is located at the lower end Ora shaft and has no step-bearing; This type of stirring mechanism, unless very accurately aligned, is likely to set up a wobble or weaving motion of theentireassembly,
The type of stirring device'in which no step-' bearingor bottom guide isprovided'iscommonly adopted when corrosive -rnixtures are -beihg worked, or in handling materials which would "affeet or be affected bymetalsf 1Unde'i :such-con- *dition'sit is desirable to construct all of the im mersedportion of the agitator'of a relatively inert material that is not readily afiected 'ifat' all, by
f themixture and wood is one such relatively inert material which is well adapted-forthis type .of
service, because it is cheap and readilyrepla'ceable. However, it has been difilcultfheretofore to attach'such' an agitator or stirrer" with an un-fl guided lower end to the driving mechanism or ment of both parts. The present invention is dian improved-construction whereby a stirrer may be-easily and quickly aligned with its supporting coupling, particularly when being replaced.
, As most stirring deviceshave vertical shafts, p the speciflcfexample of the invention shown and described herewith is designed for use in a ver- November 26, 1 214.1,- Serial No. 420,593 4 Claims. (01. 287 -126 wherein a split ring l8 is'seated so that when the socket member ID and hub member II are drawn tightly together by bolts I9 the ring I8 will. be enclosed in arelcess that is partly in each-of said members II] and II, thereby retaining the assemblyontheshaftIA.
A prime alignment of the stirrer member is obtained by relative angular alignment between the socket member Ill and hub member I I. For this purpose the top face of the flange I2 andbottom face of the flange I3' are machined at-a slight angle, that is, said faces are not perpendicular to but make anoblidue angle with the axis of the shaft I4. Thebolt's I9 passthrough close fitting holes in the flange. I2, butflange I3 is provided with arcuate slot-s29 (Fig. 2) so that the 'socket I head shaft'and readilyobtain an accurate alignrooted to the elimination of this difficulty, and to In the drawing, wherein like referenc numerv I 1 vals designate like parts throughout,
; Fig. 1 is an exterior elevation of a stirring assembly embodying this invention, only a fragmentary portion of the stirrer being shown;
Fig. 2 is a top view of Fig. 1;
Fig. 3 is a vertical central section of the asl sembly'shown in Fig. 1, on an enlarged scale; I Fig. 4 is a horizontal section-plan on line 4-4 of Fig. 3, and l Fig. 51s a perspective view of the upper end of mating flanges I2 and I3 respectively. A driving shaft I4 has a reducedend I5'that enters a central bore in the hub member II and may be held therein by a key l6 and a setscrew I'I. Near the lower end. of the portion I5 is an annular groove member Ill and hub member II may be rotated with respect to each other through several degrees' When members .I 0 and I I are so relatively rotated,'the nuts IS on bolts I9 being loosened,
the bevel of. the flange faces above mentioned I causes the axis of the members I9 and II to diverge to an increasing extent, this being one of the arrangements for obtaining required shaft alignment. vi i The socketlmember. II}, is substantiallyhollow and has at its lower end an open square socket 2! and above and coextensive therewith a, tapered round socket 22. These sockets 2i and 22 are aaaptedto receive the upper end 'of a stirrer 23 of wood, plastic, or other non-corrosive material.
Said stirrer 23 is preferably squareand has a conical or round and tapered end 24, see Fig. 5. Said conicalor tapered end 24 is slightly larger than but fits into the socket 22 of the socket member I0 while the upper portion of the square I stirrer 23 fitsinto socket 2 I.
The stirrer23 is connected to the socket member Ill by means of nuts 25" and 25' threaded respectively onto drawbolts 25 and'Zfi which extend through laterally-projectinglugs 2'! of the socket member If). Threaded pins 28 and 29, respectively, pass entirely through the stirrer 23 at'right angles to and axially spaced from each other and extend through eyelets in the lower ends of bolts 25 and 26. Spacers 3!} ar interposed between the eyelets of drawbolts 25 and 26 and the stirrer 23 to insure approximate alignment of said bolts 25 and 26 with the lugs 21. Nuts 28' and 29" are threaded onto the ends of said pins 28 and 29,
respectively. V
As the bolts 25 and 26 are arranged in quadrature, it is apparent that if any one of the nuts 25' or 26 is turned down or tightened, the en larged conical end 24 will change its position with the conical socket 22 and the stirrer 23 will be drawn toward that side. Conversely, if a nut 25' or 26 is loosened, decreasing the tension on the associated drawbolt 25 or 26 then the, tension of the other bolts 25 and 26 can shift said enlarged conical end 24 in the socket 22 and draw the stirrer 23 in the opposite direction. It is thus possible to secure a very accurate alignment of the stirrer ia with the driving shaft-I 4, and when once setup the alignment willndt change because the enlarged conical end 2401 th stirrer 23 is wedged into socket 22.
By means of the beveled meeting faces of fianges I2 and I3 and the slots 20 a semi-adjustment'of the stirrer 23 is obtained and -fifnalaccurate alignment is madeby "carefully'tightening the nuts 25' and 28' on bolts 25 and 26 as required, until the lower unsupported end "of the,
