l CENTRIFUG'L BOWL SEPRTOR Filed April 22, 1929 man ...7g/venan# (le r] Patented Dec. 30, 1930 y CARL SCHMITZ, l? OELDE, GERMANY OFFICE CENTBIFUGAL-BOWL SEPARATOR Application iiled .April 22,'. 1929, Serial No. 357,159, and in Germany April 27, 1928.

My invention relates to a collecting vessel for centrifugals working underair-tight conditions, and especiall to the coupling of the pipes for the materia to be treated with said e collecting vessel. A is This novel collecting vessel is substantially collecting vessel feed and discharge pipes, lo which are movable axially and at the same time-subjected to longitudinal pressure, be-

ing coupled to saidpipe bends. l

The advantage of .this novel device lies in the possibilit of cleanin not only the col- A1&5 lecting vesse, but valso t at feed and discharge pipes, also in the reliable sealing of the pipes with the vessel at the coupling and connection points, thus securing reliable and simple manipulation.

The accompanying drawing shows an embodiment of the invention by way of example, in Whichq- Fig. l is a cross section and Fig. 2 a plan.

The hinged collecting vessel 2, pivoted at the point 1, is provided with three collecting chambers 3, 4 and 5 for the discharge and for separating the materials to be treated, also a feed pipe 7 connected-*with the cover` with the collecting chambers', 4 and 5, and a. vertical extension ll ofl the feed pipe 7, are coupled' to corresponding pipes when the collecting vessel 2 is fixed. Air-tightness of,

the couplings is secured by the pipes being made movable axially, and by their being subjected to pressure through a spring, sealing being thus effected by them independentlyof one another wlth the possibility of compensating for possible faulty workmanf ship and other changes.

'lhe drawing only shows the pipe 12 of the feed pipe 7, said pipe 12 being similarly formed as the otherpipes of the discharge bends 8, 9 and 10. They are movable axially and ided in the holders 13 which may be attac ed to the casing ofthe centrifugal.

Springs 14 seal the coupling by exerting a` constant upward pressure, if need be, by the interposition of a jointing rin The spring, Iiressure may also be obtarne throughl corcharacterized in that pipe bends are arranged on the one-piece external casing of the hinged 6. Discharge bends 8, 9. and 10, connected respondin ly formed pipe bends and by the yielding o the collecting vessel, also through elastic elements. The extension 11 of the feed pipe 7 may either be 'rigidly connected with the pipe 7, or, as shown in the drawing,

it may be a separate piece and likewise arranged to be movable axially, 'infwhich case the spring 14 at the same time closes the connection between the extension 1l and the feed pipe 7.

@The pipe couplings of the discharge bends 8, 9 and 10, also the feed pipe l1, are preferably arranged in proximity to the pivoting point 1, thus enabling the collecting chambers to be drained when tilting the collecting e5 vessel 2. In the open position the remaining Vcontents are returned to the respective pipes through drip troughs 15 disposed on top of the pipes. The drip troughs may be omitted in certain positions. In Fig. l the dripping 7o position is shown by chain-dotted lines. If

, the couplings are in alignment, or in a similar position relative to one another in proximity to the pivoting axis, the application of the pressure for tightening the Joint is fa- I cilitated by reason ofthe greater leverage so that in most cases the deadweight ofthel collecting vessel suffices to produce the tightening pressure. Moreover, adjustment is hereby inore easily effected in case the spring 8g pressure is obtained by the bendsor other auxiliary means with limited spring -pressure. The pivot l is preferably openat the back to permit the whole collecting vessel 2 being lifted off while in the raised position withoutoslackening the bolt. Ifthe deyice is to be cleaned, the cover-6, which -is secured by screw clamps, is vtaken ofi', 'and the collecting bottoms, which are loosely fitted, re-

moved separately. lThe outside edges of the v ment,-the possibility is given of extending the outer casin of the collecting vessel over all collecting c ambers without any1 interruption, and thus locating the discharge bends in an unchaneable, secure position 5 relative to one anot er without imyairin the cleaning of the dischar e bends. pecia jointings between the col ecting chambers may be dis ensed with, and the collecting vessel may e made of great strength, a fam vorable point of the invention. The invention is also applicable without the hin e 1, in which case the collecting vessel 2is li ed off vertically in the known manner.

In all cases the ossibility7 is given of thoroughl)T cleanin t e collecting vessel and the ipes, combine with easy and safe manipuation.

What I claim is 1. A feed and collecting vessel for centrifugal apparatus, comprising an integral outer casing having a plurality of troughs one over the other and decreasing in size .from the bottom to the to a collecting chamber lid for each troug a pipe connected to each trough decreasing in size from the top to the bottom; a cover` for the casing; and a pi e secured to the center of the cover.

2. A eed and collecting vessel for centrifugal apparatus, comprising an integral outer casing having'a plurality of troughs one over the other and decreasing in size from the bottom to the top; a collecting chamber lid for each trough; a pipe connected to each trough; a cover for the casing; and a pipe secured to the center of the cover, each pipe having a drip, trough to permit axial movement of the pipes. I
