  • Patent number: 4338984
    Abstract: A funnel unit for use with automotive type vehicles. A motor vehicle requires periodic checking and maintenance of crankcase oil levels and transmission fluid levels. The crankcase oil inlet is normally near to top of the engine and is conveniently accessible. The transmission fluid inlet, however, is normally near the lower part of the engine block and this not readily accessible. The funnel unit herein has two detachable main parts which are a cone member and an elongated tube member. When these two parts are attached the elongated tube facilitates access to the transmission inlet. The elongated tube may in some cases impede use of the assembled funnel unit for adding oil to the crankcase inlet, however, and in such case the two parts are separated from each other and cone member alone is used for adding oil to the crankcase.
