Abstract: The present latch apparatus includes a swinging piece having first and second independent latches or sliders sliding in first and second slots. The first and second sliders slide independently of each other. The first and second sliders engage an undersurface of an extension of a first object such as a gate. If either the first or second slider is engaged on the undersurface, the swinging piece is locked and is not swingable such that the first object such as the gate cannot itself swing away from a second object such as a barrier section. Only when each of the first and second sliders has been slid beyond the undersurface can the swinging piece swing to permit the first object such as the gate to be released and thus swingable itself relative to the second object such as the barrier section.

Abstract: The invention is concerned with a closure clamp, comprising a carrier element (1) provided with a bearing (2), and a clamping lever (3) pivotable thereto, wherein one end (31) thereof is connected to the bearing (2) while the second end thereof includes a handle (32). To that effect, a pivotally arranged clamping element (5) is disposed on the clamping lever (3) between the bearing (2) and the handle (32) to detachably connect a locking element (6) provided on the W side of the bearing (2) facing away from the handle, to the carrier element (1). Provision is made according to the invention that, for swivelling the clamping element (5), the same is provided, on the side facing the handle, with a hand-operated lever (7).
Abstract: A double jaw latch mechanism for releasably securing a moveable structure to a keeper. The moveable structure may be an aircraft cowling and the keeper may be mounted to an aircraft structure. The double jaw latch includes a handle rotatably mounted to a housing. The handle has an open position, a closed position, and a pre-catch position. The handle is connected to a double jaw assembly which likewise has an open position, a closed position, and a pre-catch position. The double jaw assembly includes a first jaw and a second jaw mounted in pivoted relation for movement to and from each other to engage the keeper. When the double jaw latch is in the open position, the jaws are spaced apart to permit disengagement with the keeper. In the closed position, the jaws are trapped within the housing and rigidly retain the keeper.
Abstract: An improved animal litter containment and filtering apparatus is disclosed. The apparatus includes a first and second container for holding particulate litter, a coupler for temporarily securing the first container to the second container, and a filter. The second container may be inverted and temporarily secured to the first container utilizing the the coupler with the filter temporarily secured between the first and second containers. The coupler includes a first part secured to an end wall of the first container and a second part secured to an end wall of the second container. The coupler is secured to only the first and second containers, and not to the filter. The first and second parts may be temporarily engaged to temporarily secure the first container to the second container. The filter includes a filter having opposing ends, and an edge engager attached to each of the opposing ends.
Abstract: A handle operated, toggle type draw latch assembly is mountable on one of two members and is operable to selectively engage and disengage a latch-engageable formation connected to the other of the two members. The latch assembly includes a complexly configured operating handle that is pivotally connected near one end to a mounting base for movement relative to the base between closed and open positions, that provides a hand grip near its opposite end, and that, at locations between its opposite ends pivotally mounts a drawbar for movement between extended and retracted positions, and defines not only a pair of stops but also a catch-engageable formation. One stop engages the base when the handle is closed. The other stop engages the drawbar when the drawbar is retracted. When the handle is open, the drawbar can be pivoted into and out of extended positions for selectively embracing the latch-engageable formation.
Abstract: In a door arrester for motor vehicle doors, including a retainer housing fastened at a door arrangement part, door or door post, and a door holding rod fastened at the other door arrangement part pivotable around an axis parallel to the door hinge axis, where a snap-in member arranged in the retainer housing is configured as a rocking lever and is on one side loaded by a pressure spring designed as a spiral spring and on another side cooperates by way of a snap-in roller with the door holding rod, wherein the rocking lever carrying the snap-in roller is supported in the retainer housing so as to be pivotable around an axis parallel to the door hinge axis and cooperates with the door holding rod through a backup snap-in roller supported at the door holding rod around an axis also parallel to the door hinge axis, in order to achieve uniformly high and smoothly applied braking and holding forces in both directions of motion of the door, a constrained guidance curved in an arc-shaped manner is configured at the r
Abstract: A locking device has a slide accommodated in a stationary casing and spring biased in the direction causing it to project out of said stationary casing. When the slide is retracted into said stationary casing, a locking arm which is pivotally coupled to the slide is turned to a position facing the exposed end of the slide where it catches an engagement member between itself and the end of the slide. The slide can be locked in a retracted state by a cam member. When the slide is released from the locked state by the cam member, the locking arm can be brought away from the end of the slide.
Abstract: In a combination hatch cover for railway car roofs,including a large cover having a smaller cover mounted thereon, each having their own separately operable latch, a supplemental locking arrangement is provided to maintain the small cover in closed position when the latch cover is moved to open position resting on the car roof.
