  • Patent number: 4295964
    Abstract: Motorcycle apparatus is disclosed, in its preferred form, as a device for filtering and cooling oil including a novel and unique concealed mounting. The oil filtering and cooling device includes a casing having internal and external heat dissipating members for receiving and transferring heat from the oil, through the casing, to the outside ambient air or atmosphere. The internal heat dissipating members are shown in the preferred embodiment as including fins and shoulders which define an oil filter capturing cavity. An oil filter is biased inside the cavity by a spring which allows the oil to bypass the filter when the filter becomes clogged. The concealed mounting of the apparatus is accomplished by utilizing a mounting plate securable within an indentation formed in the back of the apparatus. Specifically, the mounting plate holds bolts outstanding from the apparatus through apertures in the mounting plate by capturing the heads of the bolts in apertures formed within the indentation of the apparatus.

  • Patent number: 4170260
    Abstract: A finned cooling clamp for dissipating heat from motorcycle exhaust pipes is comprised of two arcuate collar segments which can be removably interlocked together around an exhaust pipe. The collar segments are interlocked together at their opposite ends by mating locking elements. Locking heads on one end of the collar segments are apertured to receive a fastener utilized for attaching the cooling clamp to a cylinder head of a motorcycle. The interlocked clamp segments form a continuous, annular clamp conforming to the shape of a mounting flange affixed to a motorcycle exhaust pipe. The mounting flange is also apertured, and the fastener extends through it as well as through the clamp collar segments to attach an exhaust pipe to a motorcycle cylinder head.
