Abstract
Abstract A sanitary coupling for connecting the ends of flexible tubes to provide a continuous smooth flow passage therethrough. The coupling includes a fitting on the end of each tube. Each fitting includes an insert having a tubular portion and an enlarged flange portion at one end. The tubular portion fits snugly within the end of the hose with the exposed face of the flange in readiness to receive abuttingly the face of the flange on the other fitting. The edges of the tubular portion of the inserts located within their respective tubes are feathered in a fine taper to merge smoothly with the inner surface of the flexible tube. Each insert is retained in place by an outer sleeve which surrounds the end of the tube and which has a flange about its mating end. The outer surfaces of the flange on the outer sleeves are tapered to enable a locking band to be drawn tightly about the tapered outer flange and draw the fittings closely together. The abutting surfaces of the inserts are of male-female configuration to provide an effective seal.

Claim 1
Independent Claim
374 words
A hose coupling for connecting the ends of a first hose and a second hose comprising: a hollow first insert having a tubular portion at one end thereof, said tubular portion being adapted to fit snugly within the end of said first hose, the edge of said tubular portion being feathered to merge smoothly with the internal surface of the first hose; said first insert having an integral enlarged circumferential flange at the other end thereof, said flange having a facing surface formed thereon; a hollow second insert having a tubular portion at one end thereof, said tubular portion being adapted to fit snugly within the end of said second hose, the edge of said tubular portion being feathered to merge smoothly with the internal surface of said second hose; said second insert having an integral enlarged circumferential flange at the other end thereof, said flange having a facing surface formed thereon; said facing surfaces of said first and second inserts being of complimentary contour and being abuttingly mateable, said contours of said facing surfaces being constructed and arranged to present substantially continuous flow surface through said mated inserts, free of material entrapping crevices; means for securing said inserts together in said mated relation; said enlarged flanges of said first and second inserts projecting radially beyond the outer surfaces of their associated hoses; a first, outer sleeve having an internal cylindrical surface of substantially constant diameter surrounding the end of said first hose and having a circumferential flange formed about one end thereof, said circumferential flange having a shoulder formed therein for receiving said flange of said first insert, said tubular portion of said first insert and said first outer sleeve cooperating to squeeze the end of said second hose therebetween; a second, outer sleeve having an internal cylindrical surface of substantially constant diameter surrounding the end of said second hose and having a circumferential flange formed about one end thereof, said circumferential flange having a shoulder formed therein for receiving said flange of said second insert, said tubular portion of said second insert and said second outer sleeve cooperating to squeeze the end of first hose therebetween; and means for urging said sleeves together to secure said inserts together in said mated relation.
Claim 2
Dependent Claim
374 words
A hose coupling for connecting the ends of a first hose and a second hose comprising: a hollow first insert having a tubular portion at one end thereof, said tubular portion being adapted to fit snugly within the end of said first hose, the edge of said tubular portion being feathered to merge smoothly with the internal surface of the first hose; said first insert having an integral enlarged circumferential flange at the other end thereof, said flange having a facing surface formed thereon; a hollow second insert having a tubular portion at one end thereof, said tubular portion being adapted to fit snugly within the end of said second hose, the edge of said tubular portion being feathered to merge smoothly with the internal surface of said second hose; said second insert having an integral enlarged circumferential flange at the other end thereof, said flange having a facing surface formed thereon; said facing surfaces of said first and second inserts being of complimentary contour and being abuttingly mateable, said contours of said facing surfaces being constructed and arranged to present substantially continuous flow surface through said mated inserts, free of material entrapping crevices; means for securing said inserts together in said mated relation; said enlarged flanges of said first and second inserts projecting radially beyond the outer surfaces of their associated hoses; a first, outer sleeve having an internal cylindrical surface of substantially constant diameter surrounding the end of said first hose and having a circumferential flange formed about one end thereof, said circumferential flange having a shoulder formed therein for receiving said flange of said first insert, said tubular portion of said first insert and said first outer sleeve cooperating to squeeze the end of said second hose therebetween; a second, outer sleeve having an internal cylindrical surface of substantially constant diameter surrounding the end of said second hose and having a circumferential flange formed about one end thereof, said circumferential flange having a shoulder formed therein for receiving said flange of said second insert, said tubular portion of said second insert and said second outer sleeve cooperating to squeeze the end of first hose therebetween; and means for urging said sleeves together to secure said inserts together in said mated relation.
Claim 3
Dependent Claim
119 words
A hose coupling as defined in claim 1 wherein said means for securing said inserts together in said mated comprises: each of said outer circumferential flanges on said sleeves having an outer, locking surface which diverges toward the free end of its associated sleeve whereby when said fittings are mated said locking surfaces of said first and second sleeves define a combined tapered locking flange; and a locking band of generally U-shaped cross section, said locking band being adapted to be wrapped about said tapering circumferential locking flange, said locking band having sidewalls adapted to engage the locking surface of said locking flange; and means for drawing firmly said band about said combined flanges to wedge said fittings together.
Claim 4
Dependent Claim
45 words
A hose coupling as defined in claim 2 wherein said sleeves and said inserts are dimensioned so that when locked, said first and second sleeves are spaced whereby the full locking force of said locking band is applied to the mating surfaces of said inserts.
Claim 5
Dependent Claim
56 words
A hose coupling as defined in claim 3 wherein said first facing surface includes a male boss formed thereon and extending normally therefrom; said second facing surface having a female socket formed thereon receptive to said boss, said mating surfaces defining a mechanical interlock therebetween separable axially or by bending said mated along their longitudinal axis.
