Abstract: A socket wrench drive extension incorporates a quick release and locking feature. The extension is used in conjunction with a ratchet drive and standard mechanics sockets for driving threaded fasteners. The extension uses a longitudinal control bar which bears directly or indirectly on a detent contained in a transverse bore at the driving end of the extension. The control bar fits in a channel on the exterior of the extension and is operated through the retraction of a spring loaded collar.

Abstract: A support assembly is provided to support a body part, as of an automobile or other assembled article. The support assembly includes a support element on which the body part rests. The support element has a mounting plate secured on the assembly and a resilient pad portion secured to the plate. The resilient pad portion has an engagement surface which engages and supports the body part. The resilient pad portion has openings therein which soften the resilient pad portion so that relatively harder and more durable material may be used for the resilient pad portion, while still providing adequate deformation to the shape of the body part to prevent denting of the body part.

A gutter base extends generally horizontally outward from, and longitudinally along, the inboard gutter leg. An outer gutter leg extends upwardly from, and longitudinally along, the gutter. The gutter anti-clogging device includes mesh and retaining clips. The mesh, defines mesh orifices surrounded by longitudinal wire and transverse wire, and extends longitudinal along the gutter. The mesh has a L-shaped cross section with an integral inner mesh leg and an integral sloped mesh leg. The inner mesh leg is disposed adjacent the inner gutter leg and extends above an uppermost end of theouter gutter leg.

Abstract: An angled plastic tip applicator comprises a compression moulded rigid upper part including a hollow annular tip part being truncated by a convex wall being longitudinally varyingly curved at an impermanent radius. A center tube dependent from the convex wall communicates with an opening in the convex wall. A flat top cap threaded on the tip and having a serrated outer surface has a center pin engageable with the center tube for tight sealing of the applicator. The applicator has a pliable lower metal laminated plastic tubular container wall prevents leaching and pollution of the product.

Abstract: An integral false ceiling for a refrigerated vehicle body using a sealed ductwork, flow restriction and bleed means to provide selective transmission of refrigerated air to one or more cargo compartments in the vehicle body and return of air to an air conditioning unit, enhancing temperature control and minimizing intrusion into the cargo compartments.

Abstract: A latch is disclosed which is both rugged and economical. The latch includes a flanged housing which acts as a bushing for a journal portion of an operator. The operator includes a narrowed and recessed handle portion. At the inner end of the operator, a generally planar striker is placed to the interior of a door to interact with the frame. The striker rotates with respect to the housing and is limited in rotation by a stop which interacts with the housing. The striker is fixed to the operator by connector means to prevent relative movement between them. The housing is secured to the door by securement means which draws the flange of the housing against the exterior of the door.

Abstract: A railway hopper car has a pneumatic discharge structure having a throat leading to a control tube from which lading is pneumatically withdrawn. The throat is opened and closed by valve plates supported on the ends of rods extending through bearings supported in the wall of the control tube. The rods have rack structures mounted thereon operatively engaged with pinion portions of operating shafts extending parallel to the control tube. Rotation of the operating shafts causes movement of the rods and valve plates. Retainer brackets are mounted on the rack structures and include retaining portions spaced and parallel to the rack structures. The pinion portions are supported between the rack structures and the retaining portions to maintain intermeshed engagement of the pinion portions with the rack structures. Stop portions are provided on the bracket which prevent movement of the valve plates beyond the fully open and fully closed positions.
