Patent number: 5199331Abstract: 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.Type: GrantFiled: July 23, 1992Date of Patent: April 6, 1993Inventor: Kazuichi Tsukamoto

Patent number: 4818157Abstract: A quick-change adapter for rotary devices such as power drills comprises a shaft that can be inserted in a chuck of the powered rotary tool. The shaft is coupled to and is coaxial with a tool holder that inlcudes means for retaining a tool and means for driving the tool. The retaining means typically involve one or more spring-loaded balls that engage a groove or detent in the tool. The driving means include a shape that is not circular, to engage a corresponding shape on the tool to apply torque, and a surface having a component that is substantially perpendicular to the axis of the adapter to enable the application of force in an axial direction. Tools such as drills, screw drivers, and the like are rendered usable with the adapter by receiving a shaft to fit the adapter and couple torque from the adapter, a groove or detent to fit the retaining means, and a shoulder or the like to apply axial thrust.Type: GrantFiled: December 31, 1986Date of Patent: April 4, 1989Assignee: James E. ScapillatoInventor: Thomas Kouvelis

Patent number: 4811647Abstract: A tool equipped with a nut receiving socket with a tubular shaft extending rearwardly from the socket terminating in a handle. Housed within a shaft bore is a slidable pin having a forward segment normally projecting outwardly from the socket to permit manual placement thereon of washers and a nut element. The pin is biased forwardly by a helical spring with pin retraction occurring upon pin abutment with a threaded shaft to permit transfer of the washers and starting of the nut element onto the threaded shaft and the subsequent driving of the nut element.Type: GrantFiled: May 4, 1987Date of Patent: March 14, 1989Inventor: David M. Lindamood

Patent number: 4794827Abstract: A drain plug removing device includes a rotatable socket for engaging and selectively holding a head of a drain plug. One end of a flexible line is connected to the rotatable socket, and the other end of the line is secured to a support to prevent the socket and drain plug from falling further than the length of the line if dropped and to support the line and the socket holding the drain plug. A method for removing a threaded drain plug from a collection pan includes the steps of engaging a rotatable socket with a head of a drain plug, the socket having a line connected thereto, securing an end of the line opposite the socket to a support, and rotating the socket to remove the drain plug.Type: GrantFiled: March 24, 1987Date of Patent: January 3, 1989Inventor: Denzil C. Poling

Patent number: 4787273Abstract: A wrench retaining clip mounts on the shank of a wrench and is operative to retain a working head of the wrench in an engaged position on a nut or bolt head of a threaded bolt. The clip includes a channel-shaped yoke which extends partially around the wrench shank. A prong member extends longitudinally from the yoke and has a free end adapted to engage the threads of the bolt, and the yoke is slideable on the wrench shank to move the prong into and out of this engaged position. A releaseable locking mechanism is formed by a pair of resilient arcuate arms extending from the yoke in a semi-circle. These arms may releaseably embrace the working head of the wrench to lock the yoke and prong into the engaged position with the prong being biased into thread engagement. A notch is preferably formed at the free end of the prong to mate with adjacent side surfaces of the nut or bolt head where thread engagement is difficult or impossible.Type: GrantFiled: September 29, 1982Date of Patent: November 29, 1988Inventor: Donald J. Griffith

Patent number: 4787278Abstract: In a tool bit driver, a body suitable for mounting on a square drive of a socket wrench is provided with a bit socket adapted for receiving a tool bit at one end of the body, and diametrically opposed grooves are formed to extend longitudinally within the socket. A spring is provided with resilient fingers seated within the socket grooves, and reversely bent ends are formed on each spring finger for engaging the bit in surface-to-surface contact for positively and releasably securing the bit in a driving position within the socket.Type: GrantFiled: March 30, 1988Date of Patent: November 29, 1988Assignee: Western Pacific Industries Inc.Inventor: Fred A. Bononi

Patent number: 4781084Abstract: An adjustable socket-type oil filter wrench having a cup-like socket member for receiving an oil filter cartridge, a plurality of pivotable gripping arms circumferentially spaced about the socket member for radially inward and outward relative movement, and a cam arrangement for producing coordinated pivotal movement of the gripping arms for progressive gripping engagement with the circumferential periphery of an oil filter cartridge to apply removal torque thereto. The pivotal dispostion of the gripping arms enables the wrench to be used with oil filters of all conventional sizes.Type: GrantFiled: August 25, 1987Date of Patent: November 1, 1988Inventors: Carson D. Steen, Robby W. Steen

Patent number: 4777853Abstract: A tool component for supporting a fastening device (such as a bolt) in a straight and rigid position. When the head of the device and the component are inserted into a socket implement the device itself can be used for leverage to move the material objects being fastened by the device, by inserting the opposite end of said device through the holes, so as to align the holes, in the material object being fastened by said device.To support said device for facilitating the starting of the installation of same device.Said component being readily able to be removed from the device once the installation of the device is started so as not to interfere with the completion of the installation of same device.Said component (FIG. 1) comprising two device supports (20). Said supports having a cutout (22) on the inside surface of the supports, so when same are placed on a fastening device they are able to encompass a portion of the same device (26).Type: GrantFiled: August 28, 1986Date of Patent: October 18, 1988Inventor: Arlen E. Bauer

Patent number: 4744273Abstract: A generally U-shaped attachment of resilient sheet metal is adapted to be axially captured relative to the drive shank and wrench socket of a socket wrench assembly so as to extend along opposite sides of the socket and then inwardly of the fastener receiving opening in the wrench socket to releaseably retain the head of the fastener therein during application or removal of the fastener from a mating part. The inwardly extending portions of the attachment provide cam surfaces which facilitate reception, retention and removal of a fastener head from the wrench socket opening.Type: GrantFiled: June 8, 1987Date of Patent: May 17, 1988Inventor: William P. Bartok, Jr.

Patent number: 4738168Abstract: An improved wrench which retains nuts and bolts for use in areas to which access is difficult or in which there is limited clearance. The wrench includes retaining apparatus for holding a nut or bolt in place, which apparatus is internally located in the closed end of the box wrench. The retaining apparatus is slidingly mounted so it automatically adapts itself to the particular face or side of the wrench being used.Type: GrantFiled: August 12, 1986Date of Patent: April 19, 1988Inventor: Mark J. Carminati
