Abstract
Abstract An adjustable and repairable flow diverter for food processing equipment 10 includes a mounting plate 11 supporting junctions 13-15 so that a movable jumper 12 can variably interconnect pipes 27 and 28 leading to the plate. The junctions are formed as coupler tubes 23-25 with a connection at one end for the pipes and a connection at the other end for the jumper. The plate has tube holes 41 arranged to receive the coupler tubes, and the tube holes are larger than the outside diameter of the coupler tubes and large enough to allow the coupler tubes to be axially removed from and replaced in the plate. Each of the coupler tubes 23-25 has an encircling collar 43-45 with an outside diameter substantially larger than tube holes 41, and studs 46 are secured to the collars at equiangular spacing around the collars to be parallel with the axes of the coupler tubes. The plate has stud holes 56 arranged at equiangular positions around the tube holes 41 for receiving the collar studs, and the stud holes and tube holes are large enough to allow eccentric, axial and inclination adjustment of the coupler tubes relative to the plate.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
257 words
An adjustable and repairable flow diverter for food processing equipment, said diverter including a mounting plate, supporting junctions for variable interconnection of pipes leading to said plate and a movable jumper connectable between said junctions at said plate for variably interconnecting said pipes, said diverter comprising: a. said junctions being formed as coupler tubes mounted on said plate; b. said coupler tubes having means at one end for connecting to said pipes; c. said coupler tubes having means at another end for connecting to said jumper; d. said plate having tube holes arranged to receive said coupler tubes; e. said tube holes being larger than the outside diameter of said coupler tubes and large enough to allow said coupler tubes to be axially removed from and replaced in said plate; f. each of said coupler tubes having an encircling collar; g. said collars having outside diameters substantially larger than said tube holes; h. studs secured to said collars at equiangular spacing around said collars to be parallel with the axes of said coupler tubes; i. said plate having stud holes arranged at equiangular positions around said tube holes for receiving said collar studs; j. said stud holes and said tube holes being large enough relative to said coupler tubes and said collar studs to allow eccentric, axial, and inclination adjustment of said coupler tubes relative to said plate; and k. nuts on said studs securing said collars to said plates to hold said coupler tubes in an adjusted position for connection to said pipes and said jumper.
Claim 2
Dependent Claim
257 words
An adjustable and repairable flow diverter for food processing equipment, said diverter including a mounting plate, supporting junctions for variable interconnection of pipes leading to said plate and a movable jumper connectable between said junctions at said plate for variably interconnecting said pipes, said diverter comprising: a. said junctions being formed as coupler tubes mounted on said plate; b. said coupler tubes having means at one end for connecting to said pipes; c. said coupler tubes having means at another end for connecting to said jumper; d. said plate having tube holes arranged to receive said coupler tubes; e. said tube holes being larger than the outside diameter of said coupler tubes and large enough to allow said coupler tubes to be axially removed from and replaced in said plate; f. each of said coupler tubes having an encircling collar; g. said collars having outside diameters substantially larger than said tube holes; h. studs secured to said collars at equiangular spacing around said collars to be parallel with the axes of said coupler tubes; i. said plate having stud holes arranged at equiangular positions around said tube holes for receiving said collar studs; j. said stud holes and said tube holes being large enough relative to said coupler tubes and said collar studs to allow eccentric, axial, and inclination adjustment of said coupler tubes relative to said plate; and k. nuts on said studs securing said collars to said plates to hold said coupler tubes in an adjusted position for connection to said pipes and said jumper.
Claim 3
Dependent Claim
55 words
The flow diverter of claim 1 wherein said coupler tubes have different diameters and said collars on said different diameter coupler tubes have the same outside diameters and carry said studs in the same equiangular positions so that different size coupler tubes can be interchangeably mounted and adjusted in the said tube and stud holes.
Claim 4
Dependent Claim
17 words
The flow diverter of claim 1 including a sealing ring arranged between said collar and said plate.
Claim 5
Dependent Claim
41 words
The flow diverter of claim 1 wherein said collars are arranged on said coupler tubes near the ends of said tubes that connect to said jumper, and said pipe connecting ends of said coupler tubes are movable through said tube holes.
Claim 6
Dependent Claim
56 words
The flow diverter of claim 4 wherein said coupler tubes have different diameters and said collars on said different diameter coupler tubes have the same outside diameters and carry said studs in the same equiangular positions so that said different size coupler tubes can be interchangeably mounted and adjusted in the said tube and stud holes.
Claim 7
Dependent Claim
17 words
The flow diverter of claim 5 including a sealing ring arranged between said collar and said plate.
Claim 8
Dependent Claim
23 words
The flow diverter of claim 1 including tubular guards housing proximity switches mounted on said plate for detecting the position of said jumper.
