the hook 19 extends through the hanger 17 and supports one leg 20 of the carcass 11 that is to be processed as it is moved through the meat packing plant for lighter animals the trolley 18 is referred to as a gambrel not shown that supports both hind legs of the carcass 11 to be processed the dripping problem is illustrated in fig2 excess lubricant 21 around the pin 14 the arms 16 and the wheel 13 has flowed under the influence of gravity to form a drop 22 a previously formed drop 22 of the lubricant 21 is shown falling onto the carcass 11 lubricant 21 is shown on an exposed surface 23 of the carcass 11 since the lubricant 21 is only approved by the u s d a for incidental contact with the carcass the u s d a inspector must quickly find any lubricant 21 on the carcass the lubricant 21 must be removed promptly from the carcass 11 by trimming the carcass 11 and then the carcass 11 is subject to reinspection to determine that all of the lubricant 21 has been removed via the trimming operation a method of the present invention renders a carcass conveyor lubricant more drip resistant without any substantial adverse effect on the lubricity of such lubricant or the other properties desirable for a lubricant used on a trolley in a meat packing plant this involves the novel mixture of polybutene fatty acid and mineral oil the combined properties including lubricity and drip resistance of the lubricant 21 will be maximized when these components are used in the following minimum percentages by weight and with the lubricant 21 formed by such mixture having.
