Patent number: 5467621Abstract: The closure includes a base adapted to be screwed into a fuel tank filler pipe and having a fill opening normally closed by a hinged flapper which is opened when a fuel nozzle is inserted into the fill opening. The base is shielded against being manually gripped and unscrewed from the filler pipe by a cover also having a fill opening and normally supported for free rotation on the base so that turning of the cover normally is ineffective to unscrew the base. When a key is inserted into the cover, it couples the cover and the base for rotation as a unit and thereby enables the base to be unscrewed from the filler pipe. The same key also is used to actuate a locking device for locking the flapper in its closed position.Type: GrantFiled: February 10, 1994Date of Patent: November 21, 1995Assignee: Trilby, Ltd.Inventor: Marc C. Gravino

Patent number: 4986097Abstract: A locking device for tank filler tubes is described, comprising a sleeve member for insertion in the filler tube to provide smooth walls, and an annular shaped locking collar that slides inside the sleeve and fastens through the sleeve to the inside wall of the filler tube. The locking collar does not have to be removed in order to fill the tank. Two disks, having off-center openings large enough for a filler hose nozzle, are arranged one above the other in the top of the locking collar so that the top disk can be rotated to allow the off-center openings to be aligned for a filler nozzle. A cylinder lock prevents rotation of the top disk when in the locked position. An alternative embodiment of the invention does not fit inside the tank filler tube, but rather is welded or joined to it. This alternative uses a padlock which prevents a cap from being rotated to a position which aligns openings in the device, allowing insertion of a filler hose nozzle.Type: GrantFiled: July 9, 1990Date of Patent: January 22, 1991Inventor: Jay S. Derman

Patent number: 4683734Abstract: A locked cover for surrounding an air condition responsive controller such as a thermostat to prevent the setting from being altered by people unauthorized to do so. This is accomplished by baffles which are opposite the openings in the cover to prevent tools from being inserted through these openings to adjust the control. The baffles have openings through them to permit air to flow to the controller. In one form, the baffles are rigidly secured in position in an otherwise existing type of guard cover. In another form of the invention, there are a plurality of interlocking pieces which can be fitted together and placed within an existing cover to prevent access to the adjustment for the controller. In still another version, the guard cover is modified so that the openings for admission of air are not adjacent the controller, but are spaced outwardly therefrom with the openings through the baffles adjacent the controller.Type: GrantFiled: June 19, 1986Date of Patent: August 4, 1987Inventor: Carroll T. Peterson

Patent number: 4132091Abstract: A fuel cap is provided for threaded engagement with a vehicle fuel tank inlet in which a locking mechanism employs a key to move a lug from a stable locking position to an unstable unlocking position. The key may be immediately removed and the fuel cap may be threadably disengaged from the inlet and thereafter reengaged therewith once fuel has been introduced into the tank. The key need not be employed to lock the fuel cap, since once manipulation of the fuel cap to threadably engage the cap with the fuel inlet is initiated, the lug is moved from the unstable unlocking position to a stable locking position. The cap may thereafter not be threadably disengaged from the fuel tank inlet unless a key is employed to again shift the lug to the unstable unlocking position. A clutch mechanism is employed to prevent overtightening of the cap and consequent damage to the cap or fuel tank inlet, yet allow sufficient tightening to effectuate a vapor tight seal between the cap and the inlet.Type: GrantFiled: September 23, 1977Date of Patent: January 2, 1979Assignee: Orion IndustriesInventors: Ernesto M. Aro, Donald J. Shanklin

Patent number: 4107961Abstract: A locking gas cap for a threaded filler neck having a sealing lip extending peripherally about its axis, the cap comprising a closure member threaded to engage and close the filler neck, a gasket on the closure member for engaging and sealing against the lip, an outer shell providing a hand grip secured to the closure member for rotation thereon, a key-operated lock and at least one lock-actuable bolt connected to the shell for rotation therewith. A race is disposed for rotation in the shell, and a driving connection is provided between the race and the closure member which is torque limited in the direction which advances the closure member on the filler neck and positive in the cap removal direction. A spring is provided for yieldably urging the bolt into engagement with the race. The spring cooperates with a plurality of engaging pockets in the race to provide a positive driving connection between the shell and race in the direction which advances the closure onto the filler neck.Type: GrantFiled: October 29, 1976Date of Patent: August 22, 1978Assignee: Stant Manufacturing Company, Inc.Inventor: John H.

Patent number: 3998078Abstract: A limited torque cap is provided with a construction wherein a cam ring is located concentrically within a plurality of at least three radial movable jaws, normally biased inwardly and arranged to provide a driving connection with the cam ring until a predetermined level of torque is applied to the ring-jaw connection. A further construction is provided for effecting axial movement of the cam ring relative to the jaw members after a predetermined torque is achieved, whereby to prevent re-coupling of the cam ring and jaws and effectively "locking" the cap against further tightening to its connection and against removal. An "unlocking" feature permits selective restoration of the ring-jaw connection.Type: GrantFiled: June 30, 1975Date of Patent: December 21, 1976Assignee: E. Edelmann & Co.Inventor: Timothy Detwiler
