Abstract: An improved table attachment for removably mounting and rotatably mounting an attachment on a conventional table having either vertical or non-vertical legs. The improved table attachment includes a base having a top surface and a bottom surface, a support member is attached to the bottom surface of the base approximately across the centerline of the base. The support member includes a front and rear side wherein the support member defines a top elongate longitudinal threaded hole having an opening in the front side and a bottom longitudinal hole lower than the first hole and approximately parallel to it having an opening in the front side and extending through to the rear side of the support member. Structure for connecting the portable table attachment to a conventional table leg engage the top and bottom longitudinal holes and the table leg in such a manner that the table attachment is supported by the table leg and the attachment is able to rotate a limited distance laterally.

Abstract: A shelf is supported by at least one shelf support from at least one vertical support having vertically spaced slots therein. The rear edge of each shelf support carries upper and lower extensions which fit into the slots. Abutting surfaces between the upper and lower extensions extend at angles to each other and abut, selectively, the adjacent surface of the vertical support. A downwardly opening notch in the lower edge of each upper extension engages the adjacent portion of its vertical support between the slots therein while the shelf is horizontal. An upstanding projection on the upper edge of each upper extension engages the adjacent portion of its vertical support between the slots therein while the shelf is tilted. Depending projections on the lower extensions abut adjacent portions of the vertical support between the slots therein while the shelf is horizontal and are adapted to move over the portions of the support between the slots upon upward movement of the rear portion of the shelf.

Abstract: The present invention relates to a food service tray slide rail drop support bracket where an accidental or intentional vertical movement of the front edge of the rail will not induce a folding or dropping of the rail below a horizontal tray-supporting position. The rear edge is lifted for lowering the front edge.

Abstract: An arm structure for a reclining seat such as those used on planes, buses, and train coaches, in which one or both of the arms are adjustable between a substantially horizontal position when the back is in upright position and a horizontal or fully down position when the back of the seat is in a reclined position. A latch mechanism holds the arm in the various positions and is released to move the arm to any one of the positions by pulling the arm forwardly and moving it to a selected position. The arm can be lifted to any one of the positions by merely lifting the arm which snaps successively into the various positions as it is pivotally raised. The latch mechanism holds the arm rigidly in position with respect to any pressure applied downwardly thereon by the arm of the occupant of the seat. The arm rest may have one of a number of different types of upholstery or covering to match the covering on the seat.

Abstract: A combination channel post and bracket including abutting means for removably securing the bracket to the post, and enabling the vertical level of the bracket to be incrementally varied along the post. The abutting means may include an upper rod for contacting the inside of the post and a lower rod for contacting the outside of the post, and a cam for also contacting the outside of the post. The rotation of the cam provides a fine adjustment of the slant of the bracket, and simultaneously locks the bracket at the new adjusted position. For purposes of exacting adjustability, the lower rod and cam may have several removable positions on the bracket for precisely varying the incline of the bracket. A spacer may be positioned between the post and the cam, to enable the cam to provide fine adjustment of the slant of the bracket and to lock the bracket in place, for the several different positions of the lower rod on the bracket, including a reverse slant position.

Abstract: An angularly adjustable shelf supporting bracket of the type provided with a plurality of vertically spaced retaining fingers on the butt end of a shelf-carrying arm has shoulders on the upper edges of the fingers shoulders facing toward the butt end for angular position determining engagement with bars across the tops of openings in a upright supporting structure, and shoulders on the lower edges of the fingers facing toward the butt end and engageable with the bars along the lower sides of the openings for interim holding of the bracket against dropping away from the supporting structure when adjusting from one angular position to another.

Abstract: A mobile crane has a multisection telescopic boom and an optionally useable lattice jib storable alongside the boom with the base end of the jib adjacent the point end of the boom. Improved jib storage support means are provided to facilitate storing and installing the jib. Thus, one side of the boom base section is provided with a pair of longitudinally spaced apart jib storage support assemblies. Each support assembly is pivotally mounted so that it can be swung between a jib-supporting position and a stored position. Each support assembly includes a laterally extending member which is tiltable between a horizonal and a downward position so that the jib can be easily swung thereonto for storage and then subsequently locked into horizontal position, whereupon locking brackets secure the jib on the support assembly.
