Abstract: A fixed tine leaf rake having a plurality of tines connected to a brace, by a plurality of crimps with each crimp being about two millimeters or less in diameter. A curved tine support bar that has a plurality of openings fastened to the plurality of tines such that each tine fits through one of the openings. The support bar distributes the pressure exerted on each of the tines. A handle sleeve is connected to the brace by a plurality of rivets, with each of the rivets being about three millimeters or less in diameter. A handle inserted into the handle sleeve allows the user to comfortably use the fixed tine leaf rake.
Abstract: A heel stock portion of an oil seal may be made of latex elastomer based compounds instead of volatile organic compounds. One embodiment of a latex elastomer based compound may comprise approximately 5-35% aramid fiber, approximately 10-20% metal oxide, approximately 10-60% carbon filler, approximately 1-5% curative, approximately 20-50% latex flouroelastomer, and approximately 10-50% mineral filler by weight based on the weight of the heel stock part of an oil seal. Another embodiment of a latex elastomer based compound may comprise approximately 10-40% aramid fiber, approximately 2-10% mineral fiber, approximately 2-10% carbon filler, approximately 20-40% mineral filler, approximately 2-10% metal oxide, approximately 5-20% glass fiber, approximately 1-5% curative accelerator, approximately 1-5% curative, approximately 1-5% anti-oxidant, approximately 10-40% latex nitrile elastomer, and approximately 1-5% polyester fiber by weight based on the weight of the heel stock part of an oil seal.
