Abstract: A work surface is mounted on a pair of brackets which are releasably mounted on and project outwardly in cantilevered relationship from a panel adjacent the opposite ends thereof. The work surface, in each end rail thereof, mounts a manually-actuated latching lever which is biased down into latching engagement with the respective bracket. The latching lever prevents the work surface from moving away from the panel and from being lifted upwardly adjacent its rear edge. The latching lever has the end thereof accessible from beneath the rear edge of the work surface so as to be manually moved upwardly to release the work surface from the bracket, whereupon the work surface can be slidably displaced outwardly away from the panel through a limited extent. When the work surface is manually slidably moved forwardly toward the panel, the latching lever automatically re-engages its respective bracket.

Abstract: An arrangement for mounting a removable accessory such as a drawer unit to the underside of a work surface without the use of tools. A pair of front and rear slot and projection couplings are used to mount the accessory on the underside of the work surface, and a spring automatically locks the accessory to the work surface when the projections are fully engaged with the slots.

Abstract: Roadable track shoes employed on track-type vehicles, such as an agricultural tractor, each include at least one elastomeric grouser having a steel anchor plate bonded thereto. Bolting of the anchor plate on a track shoe normally provides exposed bonded edges that are subjected to high tensile stresses or failure during tractor operation. In addition, soil and the like tends to ingress into the bonded edges to further induce bond failure. The grouser assembly (11) of this invention overcomes these problems by providing a compressed lip portion (27) of an elastomeric grouser (12) between a rib (24) formed integrally on the track shoe and each outer side (28) of an anchor plate (13). In addition, a static seal (30) is formed between the lip portion (27) of the grouser (12) and the rib (24).

Abstract: A roadable track shoe grouser is provided for track-type vehicles, for example, tracked farm tractors, to prevent damage to finished road surfaces when driving such tractors upon such road surfaces. The grouser includes a rubber grouser bar which is bonded to a mounting plate to facilitate replacement of the grouser after the rubber grouser bar is worn out by use. Owing to interruptions in the bond provided to accommodate the heads of track shoe retaining bolts underlying the grouser, the bond is subject to premature failure, resulting in the loss of the rubber grouser bar from the track shoe. The grouser 10 described herein solves this problem by using a mounting plate 32 having an aperture 45, the aperture 45 is of a size to receive a head 28 of a track shoe retaining bolt 25. A plug 50 is of a size and construction to be press fitted into and close the aperture 45 and to provide a continuous, uninterrupted bond interface across the mounting plate 32.
