  • Patent number: 5199331
    Abstract: A drain plug remover for vehicle engine oil pans includes a drain plug holding socket, a shield member and a handle. The socket, made of a resilient material, is formed having an open end which is slightly smaller than the head of the drain plug and includes longitudinal slits in its side wall, wherein, when the socket is pressed upon the drain plug, the socket expands to grasp the plug. An alternative means of holding the drain plug is by use of a magnet located within the socket. A shield member extends outwardly from the base of the socket, preferably in the form of a plate having an outer lip which curves towards the open end of the socket, thereby forming a concave, saucer-like receptacle to initially catch and subsequently deflect the flow of dirty oil away from the hand of the user. Extending from the shield member, opposing the socket, is a handle which the user grasps during removal and replacement of the drain plug. The handle includes longitudinal ridges to aid grasping and rotation of the tool.

  • Patent number: 4759395
    Abstract: The bead breaker for vehicle tires involves a hydraulic jack member whose base is attached to a bead pressing member and whose extendable head is connected by tension members, such as a chain and hook combination, to the wheel. The bead pressing member may have alternative configurations, one being an adjustable split presser assembly comprising a presser arm, attached to the jack base, upon whose opposing extended arms are slidingly mounted adjustable sleeves. Attached to each radially adjustable sleeve is an arcuate presser section which presses downward against the tire bead when the jack head is extended, breaking the bead. In the alternative bead pressing member, the presser arm, attached to the jack base, is removably attached to a ring presser member, which presses against the tire bead along a full 360-degree circumference.
