Abstract: A battery tray for an automotive vehicle is constructed for use as a replacement item and is adapted to receive the great majority of commercially available lead storage batteries. The battery tray is constructed with a rectangular floor bounded by edge retainers and with three spaced sunken wells arranged along the length of the floor. A pair of spaced apart elongated slots are defined in each of the end wells parallel to the longer floor sides and a circular aperture is defined therebetween. At least one elongated transverse slot is defined in the center well.

Abstract: A threaded cap for sealing an automotive vehicle fuel tank is provided with a unitary molded central plastic core and a bonnet rotatably mounted on the plastic core. A pair of concentric races are defined on the plastic core. The inner race carries a unitary molded plastic frame which has a pair of resilient, closely spaced transverse cantilevered arms defining a gap therebetween. The frame is also provided with a resilient catch. A unitary molded plastic bolt is reciprocally movable along the gap to engage and disengage the core for rotation with the bonnet. The bolt has two detents which coact with the catch on the frame to hold the bolt at selected unlocking and locking dispositions of movement. The bolt includes a stud which projects into the gap between the arms so that the arms spring bias the bolt toward the locking disposition. A lock mechanism is used to shift the bolt to an unlocking disposition so that the fuel cap be disengaged from the fuel tank inlet pipe.

Abstract: A simple fuel consumption efficiency gauge employs a pointer mechanically coupled to the extremity of a Bourdon gauge. The pointer is electrically coupled to vehicle ground and is bracketed by two contact posts associated with high and low fuel consumption efficiency, respectively. Contact by the pointer with either post completes an electrical circuit through a corresponding light emitting diode to signal good or poor fuel consumption efficiency. When the pointer is between the contact posts, current is continuously supplied to another light emitting diode through a load in order to signal fair fuel consumption efficiency. The device is housed in a casing adapted for connection to similar casings by means of clips and clamps.

Abstract: A disk shaped air freshener includes opposed mating trays which define a cavity therebetween and which are engaged for rotation relative to each other. Windows are defined in both of the trays, and openings to the cavity are increased, decreased, or shut entirely by relative rotation of the trays to alter the alignment of the windows. One tray has an axial sleeve and the other has several cantilevered arms which fit through the sleeve and which engage a radial groove in the sleeve to the hold the trays together in relatively rotatable fashion. A scented element is confined within the cavity between the trays and is allowed to provide a freshening scent through openings defined by the aligned windows in the tray. An adhesive pad is centrally located on one of the trays at the axial center of the air freshener.

Abstract: A spark plug cleaner is constructed as an upright canister with outwardly directed openings into which spark plugs are inserted. A vertically mounted motor driven impeller sucks grit from an axial center of the canister and flings it toward the spark plug sockets. A grit recovery floor is provided below the impeller and sockets and is configured concave upward. A suction guide fits coaxially over the collection floor and also slopes concave upward toward the center of the impeller. An annular vacuum channel is formed between the collection floor and the suction guide to concentrate impeller suction on spent grit as it falls to said collection floor and to increase grit velocity and density to the impeller.

Abstract: An oil dispensing device is provided with a funnel and with a cradle located at the funnel mouth for releasable, rotatable interengagement therewith. The cradle has a chute with an upwardly directed piercing blade at its lower extremity and a trigger mechanism for forcing an oil can down onto the piercing blade at its upper extremity. Rotation limiting stops on the cradle and funnel prevent the chute from being rotated upward beyond the edge of the mouth of the funnel.

Abstract: An annular gasket is formed with a tubular sleeve of flexible material. At the interior surface of one end of the sleeve a lip is directed a short distance radially inwardly. At the opposite end of the sleeve, a recess is defined in the interior sleeve surface to receive the lip when the tubular sleeve is folded back upon itself to assume a generally toroidal configuration. The gasket interiorally receives cylindrical members of one diameter when the sleeve is in its extended condition and cylindrical members of a narrower diameter when in its toroidal configuration.

Abstract: A drinking container is provided with a removable cap engageable with a cup in sealing arrangement. A drinking opening is provided in the cap and is normally sealed shut by a spring biased plug. A trigger on the exterior of the cap, when actuated, withdraws the plug from the drinking opening to allow the user to imbibe a beverage.

Abstract: An omnidirectional, vertically polarized antenna having a lower, 1/4 wavelength skirt made up of circumferentially-spaced arms which extend down from the lower end of a vertical, 1/4 wavelength, upper radiator at an angle between 12 degrees and 25 degrees, and preferably 17 degrees. The upper radiator carries a multi-spoke capacity "hat" to increase its electrical length.

Abstract: An air freshener for use, for example, in an automotive vehicle in which an annular scented pad is disposed within a hollow housing formed of mating, shallow, pan-shaped tray sections. One of the tray sections includes an annular axial hub. The other tray section has a guide extending outward therefrom and engageable with the hub to releasably secure the tray sections together with the scented pad entrapped therein. A restraining ridge about the hub holds the pad in position. A double sided pressure sensitive adhesive is fastened to one of the tray sections and is used to secure the housing to a surface within the atomotive vehicle in immobile fashion.

Abstract: There is disclosed an adjustable oil filter wrench including a bearing shoe formed with a cylindrically shaped bearing pad for complimentally fitting the circumference of an oil filter cartridge and turned back along its opposite sides to form upstanding parallel ears formed with a pair of aligned diametrically projecting adjustment slots which turn laterally at their outer extremities to angle radially inwardly for a short distance to form a small filter cartridge leg. A transversely extending pivot pin is slidably received at its opposite extremities in such slots and has one end of a handle connected therewith and normally projecting laterally in one direction therefrom. A flexible band is connected with such pivot pin and projects in the direction opposite the handle and loops about the bearing surface to cooperate therewith in forming a cartridge engaging loop and has its opposite extremity connected medially with the handle.

Abstract: Antenna having a selectively rotatably extendable sensitivity pattern provided by an array of three or more dipole antenna units, each of substantially equal mechanical length and located at the corners of a substantially regular polygon having the same number of sides as the number of units in the array and switching means having connections to each dipole unit to selectively energize at least one of said units and interpose an electrically-lengthening inductive reactance in at least two other units located, with respect to the direction in which the sensitivity is to be extended, behind and on either side of an energized unit to serve as parasitic reflectors extending the lobe of sensitivity of an energized unit in the selected direction.
