Abstract: A dogging device for securing a panic exit and actuation device in an unlatched condition. The dogging device uses a U-shaped spring clip to secure a base plate, a dogging adapter and a dogging hook together. The base plate, dogging adapter and dogging hook are rotated about a common axis by an operator, which can either be a hex shaft or a cylinder adapter operated by a keyed lock, from a disengaged position to an engaged position where the dogging hook engages a control rod of the exit device thereby holding, or dogging, the exit device in an unlatched condition. An over center spring is used to bias the dogging hook into either the engaged or the disengaged position.

The first outer transverse member, the first outer longitudinal member and the middle transverse member define a first lobe. The first lobe is rotatable to engage the windshield by a second lobe defined by the middle transverse member, second outer longitudinal member and second outer transverse member, the second lobe functioning as a handle.

Abstract: A tray (10) for removably supporting useful objects such that the objects are stationary in order to facilitate their use by disabled persons. The tray (10) includes a tray body (12) defining an upper work surface (14), and defining at least one opening (16) therein. The tray (10) also includes at least one object supporting insert (18) for being removably received and supported in the opening (16) in the tray body (12). The object supporting insert (18) defines an upper surface (30) on which the useful object is secured, such that the useful object is maintained in a stationary position to facilitate its use as the object supporting insert (18) is positioned in the opening (16) in the tray body (12), yet can be removed from the tray body (12) through the removal of the object supporting insert (18).

Abstract: A ventilation stop for limiting the length of movement of a slidable door or window sash. The ventilation stop is located in a fixed element of a window or door assembly, preferably in an interior glazing stop of a fixed sash adjacent to the slidable sash. The stop includes a recess in the glazing stop, a tab disposed in and protruding from the recess, and a hinge pin disposed in friction fit through a bore in the tab and extending into the glazing stop beyond the recess, preferably in both directions from the tab. The axes of the bore and the pin are parallel to the direction of movement of the slidable sash, permitting the tab to be turned into an interfering relationship with the slidable sash, thereby limiting the length of movement of the sash, or to be turned out of interference, thereby permitting unrestricted movement of the sash. Preferably the glazing stop is hollow, allowing for easy insertion of the pin into the tab from within the glazing stop during assembly of a window or door unit.

Abstract: A coupling device for connecting a heald shaft to a heald drive such as a push-pull rod and for disconnecting the heald shaft from the heald drive such as a push-pull rod has a plug-in member connected to the heald shaft and a socket member connected to the heald drive. The socket member is equipped with a toggle mechanism for locking and unlocking a pawl that engages or disengages the plug-in member. The toggle mechanism is spring loaded so that a separate locking device is not necessary. A plurality of such coupling devices are arranged in groups for operation in unison by a drive mechanism that includes a cam drive for each coupling device. All the cam drives for a group of coupling devices are secured to a splined shaft for operation in unison so that all coupling devices can be coupled or decoupled simultaneously.

Abstract: A removable passenger control unit (20) is detachably latched in position in a recess in the arm (12) of a passenger seat by means of a rotatable C-shaped pawl (40) that is mounted on a support arm (54) that projects into a recess (48,50,52) in an end of the passenger control unit. The legs (70,72) of the pawl straddle the support arm, and one leg (72) is threadedly engaged with a cap screw (60) that is rotatable and slidable in an aperture at the end of the support arm. The other leg (70) of the C-shaped pawl (40) has an aperture that receives an enlarged head (62) of the cap screw. The arrangement allows the pawl to be rotated between latched and unlatched positions and to be shifted axially of the cap screw by rotation of the cap screw. The capture of an upper leg (70) of the C-shaped pawl by the enlarged head (62) of the cap screw resists tilting moments exerted by engagement of the pawl with a panel edge ( 18) of the passenger seat.

Abstract: A pawl assembly comprising a threaded shaft of noncircular cross section, a pawl of generally elongate shape having a circular through hole, and a clip that is nonrotatably mounted on the shaft and which contacts the pawl to prevent rotation thereof. The clip has a noncircular through hole that corresponds to the noncircular cross section of the shaft and a bent portion that contacts a side surface of the pawl to prevent rotation. By using such a clip, the pawl can be oriented in multiple angular directions while also providing for precise axial placement on the shaft. The pawl assemblies may be used in latches for cabinets and the like.

Abstract: A lock bolt designed to mount in a door jamb, and designed for use in applications such as penal institutions. The lock bolt has two warped surfaces that are exposed to a closing door. The door contacts the first warped surface along a length of that surface, forcing the lock bolt back into a housing. The two warped surfaces are designed such that the door never contacts the second surface. Therefore, the design allows for greater protrusion and greater width of the lock bolt.

Abstract: A fastener removably clamps the edges of two panels each having a hole therethrough. The fastener includes a hinge pin, about which the fastener body pivots. To clamp the panels, the hinge pin is extended through the holes in both panels to align the panels and then the fastener body is pivoted so that its top flange portion lies on one panel and its bottom flange portion lies on the other panel, thereby clamping the panels between the two flange portions of the fastener.

Abstract: A concealed connector for detachably coupling two panels together comprises a keeper entirely recessed within an edge of one panel and a rotatable latch outwardly projecting from a surface of the other panel. The latch includes a cam portion in the form of a partial thread which is inserted within the keeper recess for engagement with a flanged lip on the keeper. A stylus key is passed through a narrow access slot in communication with the recess and is selectively received within circumferentially spaced holes in the latch periphery. Turning of the latch in one direction by the key draws the abutting edges of the panels together in locked disposition while turning the latch in the other direction effects release.
