Abstract: A wall-mounted shelving system provides for easy installation and adjustment in any number of configurations. The system includes at least one pair of vertical standards adapted to be mounted on a wall or similar supporting surface. Each standard is generally U-shaped with a backwall member adapted to be placed flush against a wall and two opposed arms extending outwardly from the backwall member. The backwall member is secured to the wall by rivets or any other suitable fastener. A ceiling mounting plate provides additional support for the standard. A plurality of keyhole slots are spaced along the pair of standard arms to receive shelf support brackets at any number of desired locations along the standard. The brackets are provided with shoulder rivets for removable engagement with the keyhole slots. The shelves are designed to snap fit over the front and back portions of the brackets to provide a secure engagement against accidental dislodgement.

Abstract: A device for separating unpopped popcorn kernels from popped popcorn. The device comprises a flat flexible disc having tapering edges, feet or ridges to elevate the disc, and a plurality of holes perforated through the disc. The diameter of the holes will only allow unpopped popcorn kernels to fall through the disc, and not popped kernels. Therefore, regardless of whether the disc is supported at its edge of its feet, there is space for the kernels to fall through.

Abstract: A rack system of adjustable shelves has a simple and economical shelf assembly mechanism. A shelf is attached to its supporting vertical posts by placing each of the posts through an individually associated corner shelf socket. The shelf is kept in position by a plastic keeper which can be moved up and down the post to the desired height of the shelving. The keeper has a generally truncated pyramidal shape and at least one internal projection which fits into a dimple, recess, or notch formed in the post at the desired shelf height. The keeper has vertical slots that enables it to be squeezed together and to tightly wedge into the shelf socket and support the shelf on the corner post. The system can be adapted to both square and circular posts.

Abstract: An all plastic shelf is part of a shelving system and is provided for uses where metal shelves might rust or corrode, especially if attacked by hostile chemicals. The underside of the plastic shelf has a channel formed around the periphery thereof. A welded metal frame fits into the channel, with either the width of the frame or a cover plate substantially covering the channel in order to prevent an entry of foreign matter therein. Sockets are formed in the corners of the frame to receive corner posts for supporting the shelf. These sockets fit into corner sockets which are molded into the metal frame.

Abstract: Slats fixed to a vehicle deck have external-flange tracks along their opposite edges. Brackets engage these tracks--by a lip that projects inwardly from the side wall of each bracket to capture the flange. The brackets can be slid by a user along the tracks and locked at any point along the slats by clamping plates inside the brackets. The clamping plates are forced against the slats as by screws in the tops of the brackets. One type of bracket carries an arch-shaped tie-down member and is also adapted for attachment of crossbars, spanning the outboard slats, but only at certain discrete points along the slats. Each tie-down member is fixed to its tie-down bracket below the inwardly projecting lip, or in any event at a point in the side wall, of the bracket. This configuration preserves clamping force when a strap or cord is tightly cinched from the bracket over luggage, resulting in very strong upward force on the tie-down member.

Abstract: A fence or partition for a flat shelf is provided that can be installed at different locations on the shelf and can be made in various sizes. The partition comprises a rectangular frame formed from a bent rod with at least one post attached to the frame perpendicular to the length of the frame. The post extends below the frame and is removably secured in a step clip. The step clip is designed to removably fit on the shelf.

Abstract: An inverted U-shaped clip is provided for coupling together shelves on adjacent shelving units. The clip body comprises a pair of spaced-apart parallel sidewalls and a top wall connecting the sidewalls. A first pair of projections extends outwardly from one side of the two sidewalls and each terminates in an upwardly extending hook. With the clip body, the first pair of projections form a first shelf-receiving space. From the opposite side of the clip body, a second pair of projections extends outwardly from the clip, each terminating in an upwardly extending lip. A tongue extends outwardly from the top wall above the second pair of projections and from the same side of the clip body as does the second pair of projections. The tongue terminates in a downwardly extending lip, and with the second pair of projections and the clip body, forms a second shelf-receiving space.

Abstract: A shelving system is provided for mounting on a wall or similar support surface. The system can comprise one or more shelves at varying heights to accommodate different storage requirements. At first top shelf is mounted on the wall by means of a pair of c-shaped brackets that are secured to the wall and removably hold the back of the shelf and by a pair of braces, each secured to the wall at one end and to opposite sides of the shelf at the other end. Another shelf can be added to the system below the top shelf by means of a second pair of c-shaped brackets secured to the wall below the first pair of brackets and by a pair of support members secured to the top shelf that extend downwardly to support the second shelf. Further shelves can be added to the system below the second shelf in the same manner.

Abstract: A spray head assembly is made from a very few number of injection molded parts. Preferably a pair of elongated housing shells fit together in face-to-face confrontation, with a spring biased actuator arm or control lever pivotally mounted between them. The lever has a metal shaft extending therefrom, which passes through a flexible cone in a rubber bulkhead to maintain a waterproof seal. In front of the bulkhead is a solid plastic plate having mounted therein a reciprocally slidable member controlled by the lever. In one embodiment, the sliding member contains a generally triangular or tapered opening or openings having a sector of a circle for a base. Depending upon the position of the slide, the opening moves up or down to open or close a water passageway through the spray head. The sliding member first presents the smaller sectors of the opening or openings to an associated sealing ring to minimize the abruptness of any change in discontinuity of water flow at the edge of the opening.
