Abstract: A cover for a hatch which will engage with a rim to produce a water tight seal. The hatch cover includes a plate capable of seating in the rim and a shaft extending vertically through an aperture in the plate and slidably received therein. A handle is located on one side of the plate, one end of the handle pivotally connected to the shaft so that the handle will move from a closed position parallel to the plate to an open position substantially perpendicular to the plate. The handle imparts vertical movement to the shaft with respect to the plate. Arm assemblies extend radially outward from the shaft on the side of the plate opposite the handle, whereby movement of the handle imparts movement to the arm assemblies thereby extending the arm assemblies to engage the rim.

Abstract: A reinforcing latching means for maintaining the integrity of the upper tailgate-sidewall joint closure in a refuse carrier with a vertically hinged tailgate assembly including a handle disposed along the bottom of the tailgate which mechanically rotates a vertically oriented control shaft and is operatively connected to at least one horizontally disposed latching rod means horizontally moveably along the tailgate for controlling the engaging and disengaging of said at least one latching rod means with a latching plate means disposed along the exterior lateral surface of the sidewall.

Abstract: A quick-set engaging and release spacer-connector assembly permits two cabinet modules to be fixedly connected side-by-side by manual operation of upper and lower internal lever handles which sit inside the assembly. A lateral drawing force operates to seal the cabinet modules with RFI/EMI gaskets on the periphery of each side of the spacer connector assembly.

Abstract: A swivel fitting for an outwardly opening window, with a device for moving the casement frame between the closed position and the open position, for example in the form of a hand crank, with position-fixing arm driven by the crank and with an operating handle on one frame member of the stationary frame, in order to fix the casement frame in the closed position. At least one locking plate is included on the casement frame which co-operates with a locking element on a drive rod operable by the handle. When the window is in the closed position, a locking projection of the locking plate protrudes into a groove in the stationary frame so that the closing movement of the window may be supported relatively early by actuation of the handle and to ensure high security against break-in.

Abstract: Upper and lower sectional doors of rectangular configuration are mounted within an aircraft fuselage door frame and hinged for pivoting about horizontal axes at the upper and lower horizontal edges of respective door sections. A step is mounted to the interior of the lower door for pivoting along one horizontal edge about a horizontal axis between a first position with the step flush with the door interior and a second position projecting generally at right angles thereto. A plurality of laterally slidable latch pins fixed to the lower door section along vertical side edges are projectable into holes within the fuselage doorframe through a linkage system coupled to a shaft pivotably mounting the step to the door. The latch pins are projected to latching position when the step is folded flush to the door and retracted to unlatched position by manual movement of the step to its projected position prior to opening the lower door.

Abstract: In a first embodiment thereof, the locking means comprises an axially-translatable bolt slidably disposed within a cylinder. The cylinder has an axially-extended slot formed therein, and a pin fixed in the bolt projects therefrom, through the slot, to engage a camming slot formed in a sleeve which envelops the cylinder. A hollow cap-actuator envelops the camming-slotted sleeve, and a drive rib formed in the cap-actuator engages an axial separation in the sleeve to cause (a) the sleeve to rotate, when the cap-actuator is turned, (b) to cause the pin to travel along the camming slot, and (c) to effect extension and retraction of the bolt.

Abstract: A lock mechanism is disclosed for use with sliding, swinging or overhead doors. A receiver is affixed to the door frame and a bolt, linkage and handle are affixed to the door. The linkage allows the bolt to engage the receiver by sliding along the receiver until it becomes latched so that the door may be closed though the handle is locked. Pulling upon the unlocked handle retracts the bolt from the receiver and also causes the door to start opening.

Abstract: An adjustable and releasable locking device for a removable vehicle roof panel is disclosed. A rotating lever longitudinally projects a pair of tapered pins which mate with apertures in the windshield post and headliner. The transverse and vertical position of the tapered pins is adjustable to position the panel relative to other parts of the vehicle and provide a smooth transition between the vehicle roof and the removable panel and provide an adequate seal between the vehicle and the removable panel.

Abstract: What follows is a description of a mechanism for displacing structurally related component parts of a larger assembly of parts relative to each other. The component parts are typically locked together into the larger assembly and the mechanism is designed to first unlock the component parts and thereafter produce the relative displacement of the component parts. The mechanism is also designed to reverse the noted procedure and first produce the relative displacement followed by locking of the component parts. The procedure is effected using a single actuator and a continuous operation.

Abstract: A latching assembly for latching the swingable door associated with a cap as mounted over the bed of a pickup truck. The latching assembly is activated by a manually rotatable handle mounted centrally of the lower edge of the door. The latching assembly includes a pair of elongated rigid rods which project outwardly toward the opposite sides of the door and have latching bolts mounted on the free ends thereof, which bolts are disposed for latching engagement with the adjacent side jams. A removable fastening element, such as a screw, coacts between each bolt and the respective rod for permitting the bolt to function either as a deadbolt or as a spring-bolt. When the fastening element is present, the bolt is rigidly secured to the rod and functions as a deadbolt so that the handle must be manually rotated to move the bolts during both opening and closing of the door.

Abstract: An operating mechanism for a pair of sliding doors includes a rotatable cam actuating member for locking and unlocking one door relative to a door opening of a vehicle. The other is provided with locking bolts which are also actuated by the cam actuating member and include means selectively engageable with said locking bolts whereby both doors may be locked and unlocked simultaneously or only the first door may be so actuated.

Abstract: A lock of the type enabling panic exit, there being a unique drive arrangement from the inner knob to the latch bolt mechanism and the security dead bolt mechanism. This drive utilizes a vertically reciprocable slide at the inside of the door panel, biased in one direction, and shiftable in the other direction by rotation of the inner knob for retraction of both the latch bolt and the security dead bolt. The drive is not responsive to tampering with the spindle elements, e.g. after forced removal of the outside knob. The lock can be employed on either left or right-hand door arrangements, directly, without requiring handing.
