Abstract: A pair of doors hinged to a frame and including a self-locking three-point latch and coordinated closing system.

Abstract: A coupler which is for tubing and which has a tube receiving bore therein. A sealing ring, spacer ring and lock ring are coaxially located within the coupler bore. When a tube is inserted into the coupler bore, the sealing ring makes contact between the coupler and tube with the spacer and locking ring cooperating to cause the locking ring when the tube is pressurized to firmly engage the tube, thus preventing the tube from being withdrawn from the coupler.

Abstract: One or more mercury displacement switches are positioned against a plate-shaped mounting bracket and interlocked to the plate by means of a strap extending around each switch and through the mounting bracket.

Abstract: A skirt secured to a vehicle wheel well and having a channel part through which fasteners extend to connect the skirt to the peripheral edge of the wheel well. A deformable flexible tape is applied over the fasteners within the channel part of the skirt to hide the fasteners from exterior view.

Abstract: A device for testing inflated objects such as tennis balls, wherein a housing contains a testing chamber in which the inflated object is compressed in a testing operation to an extent correlated to its inflation pressure.Measuring means calibrated to indicate inflation pressure are carried by the housing and include a sensing member contacting the object being tested and displaced in said testing operation from a normal position to an extent dependent upon the inflation pressure of said object.

Abstract: A scope which is for viewing the internal surface of a bore or similar cavity and which includes a rod having a viewing end and an image transmitting end. The rod is formed of optically clear light transmitting material through which the internal surface of a bore or similar cavity at the image transmitting end of the rod is viewed from the viewing end of the rod. The transmitting end of the rod includes an optical surface paralleling the axis of the rod. A pair of circular gauging indicators are formed on the optical surface and are spaced a selected distance apart along the axial direction of the rod to permit a selected part of the internal surface of the bore to be viewed between the indicators for measuring purposes.

Abstract: A fishing lure having an elongated body with an angularly extending apertured diving plate and a line guide spaced longitudinally and rearwardly from the diving plate. A fishing line extends freely through a diving plate aperture and the line guide and has a hook attached thereto in a manner to push against the line guide to advance the lure body during trolling and retrieving.

Abstract: A liquid filter having a housing which includes a chamber enclosed by a cap. A reticulated basket is fitted within the housing chamber and supported by the housing. A filter bag is positioned within the reticulated basket and includes a flexible flange which engages the housing to secure the bag within the basket without the aid of the filter cap.

Abstract: A windshield wiper arm is formed of a single metal blank bent to different cross sectional configurations along its length to strengthen and reinforce it, and including a long substantially tubular portion intermediate its ends. A windshield washer nozzle is mounted at the free end of the arm and is supplied by an elongated liquid tube concealed and protected within the arm by the tubular portion of the arm and by the coil spring urging the arm toward the windshield.

Abstract: A vehicle anti-theft device which when activated by the vehicle user causes the fuel tank to be isolated from the internal combustion engine of the vehicle and simultaneously therewith causes the fuel gauge to register empty, thereby restricting movement of the vehicle upon unauthorized usage and creating the impression that no fuel is available for the vehicle.

Abstract: A chassis for a mobile home having outriggers which project laterally from the longitudinal frame members of the chassis and which are each formed of a return bent, one piece construction.

Abstract: A walking beam is located under each of the main longitudinal members of the vehicle frame and carries at each of its ends a wheel spindle journaling a wheel for ground engagement. A shock absorbing resilient member is carried between upper and lower supports connected respectively to each main longitudinal member and walking beam. A pivot member is mounted to the walking beam below the lower resilient member support and serves to define the pivot axis for each walking beam. Each pivot member is connected to the vehicle frame by a transverse pivot shaft and is braced by a longitudinally extending strut.

Abstract: A window assembly which is for mounting in a four-sided vehicle body opening and which includes a rigidifying frame having open ends receiving glass end panels. A glass center panel is carried by the assembly frame and is shiftable over a center opening formed between the two glass end panels.

Abstract: A watertight vertically elongated rigid shell or hull of a size small enough to be transportable over highways has a detachable snorkle extending from its top and contains a power source which may be used to drive pumps within the device and/or to drive mechanical devices, such as rotating blades, winches, belts, drills or propellers, which are located externally of the hull. The hull of the device is divided into upper and lower compartments, of which the lower compartment can be completely or partially flooded with water which acts as a ballast helping to stabilize the device and controlling submersion thereof and its submerged position.

Abstract: A hub which is mountable to a spindle shaft and which is utilized for the purpose of adapting the shaft to accommodate a reel of differing type from that normally carried by the shaft. The hub includes a side wall carrying a plurality of spring biased plungers which are designed, when the hub is attached to the spindle shaft, to lock the reel to the hub in such a manner that more force must be exerted to remove the reel from the hub than to place the reel upon the hub.

Abstract: An electrostatic hand-held coating-dispensing apparatus includes a first pulley, a second pulley, and a continuous belt trained about the first and second pulleys. The first and second pulleys are supported and retained in spaced apart relation to maintain tension on the belt in a supporting housing. A first brush is provided adjacent the belt where the belt is trained about the first pulley. A second brush is provided adjacent the belt where the belt is trained about the second pulley. A curved conducting surface is also supported by the housing. The second brush is connected to the conducting surface. A small alternating current electric motor is provided for turning the first pulley. A container or canister is provided for the coating material. The canister is snugly received in the supporting housing in a position adjacent the conducting surface. The canister includes an end for transferring electrostatic potential from the curved surface to the coating material therein.

Abstract: A vehicular planter for trees, herbs, shrubs and similar plants in which a trough which is transversely oriented relative to the direction of movement of the planter is formed in the ground by a fore and aft moving blade. A conveyor carried by the planter positions a row of plants with their roots extending into the trough. Thereafter, the blade of the planter forms a second trough adjacently ahead of the first formed trough and simultaneously therewith causes the second trough to be filled with dirt to cover the roots of the plants located in the first formed trough. This sequence is repeated to produce multiple rows of plants in the ground.
