portion of the feed line 15 a lower clamping block 31 k supports the line 15 against the underside of clamping arm 31 i and is held in position by hardware members 31 l universal joint 40 is designed for use in washdown environments such as found in food processing plants all of the parts may be made from stainless steel parts in rubbing contact with other parts e g spider block 42 ball bearings 49 and bearing pads 46 may be made from different stainless steel alloys to minimize galling or other forms of abrasive wear contact surfaces between parts which are difficult to keep clean in food processing areas are kept to a minimum yoke arms 44 45 may be designed to provide generous clearance to the central spider box 42 so it is easily washed with a water and or steam stream not shown other washdown proof materials known in the field of food preparation e g delrin u00ae may be used the universal joint 40 is also designed to be easily maintained over time the bearing pads 46 bearings 49 and the spider block 42 may wear by loosening bolts 47 yoke arms 44 45 may be repositioned to move bearing pads 46 closer to spider block 42 to accommodate minor wear also the shank portions 46 a of bearing pads 46 may be threadably engaged with yoke holes 54 so that the pressure of the bearing pads against the adjacent face of the spider block 42 may be adjusted when bearing pads 46 u201c wear out u201d yoke arms 44 45 may be removed and new bearing pads 46 may be.
