Abstract: A reduced arc box end ratchet wrench or ratchet drive wrench utilizes a multiple pawl ratchet assembly comprised of a body having an insert cavity to enclose critical components of an insert that is secured within the ratchet assembly. The insert is set into the wrench body and includes a plurality of pivoting pawls. Each pawl comprises a lever arm with ratchet engaging teeth. The pawl arms are positioned relative to the ratchet wheel to create “pawl swing arcs” and “reduced ratcheting arcs” to alternately or successively engage a portion of the teeth of a ratchet wheel at all times. This configuration allows smaller degrees between ratchet teeth and a smaller wrench rotation that is otherwise required to apply torque.

Abstract: The present invention is a dust collection assembly for capturing dust, debris and residue that is created during the process of drilling holes into a concrete ceiling. The dust collection assembly is used with a universal drill stand and a drill saddle which has an electric drill secured to it. The drill saddle further comprises a telescoping vacuum tube having a ceiling contact portion that encircles the drill bit at the portion of the drill bit where the drill bit enters the ceiling. As the drill bit begins to penetrate the ceiling, silica dust is generated and removed via the vacuum tube, which tube is connected to a vacuum source.

Abstract: An apparatus and system comprises a pole having a top end and a bottom end. The top end is used adjacent a ceiling. The bottom end is used by an installer who is standing on the ground below the ceiling. The present invention is intended to be “modular,” the top and bottom ends being like-configured such that either end can be used as the top end or as the bottom end. Exemplary accessories are shown and described, each of which is disposed in a top end position. There are two types of accessory items contemplated by this invention. First, are fastening tools which are, for the most part, common utilitarian tools used with some sort of specific adapter and/or coupler. Second, there are proprietary accessories, which include offset couplings which can be used to drill and then impact or screw/torque a fastener into an aperture following drilling.

Abstract: In the combination of a shelf and a shelf-supporting apparatus, the shelf has a longitudinal axis and an end surface coincident with such axis. The apparatus supports the shelf at the shelf end surface. In the improvement, the shelf includes first and second support pins extending from the end surface in a direction parallel to the axis. These support pins define a first spacing dimension. The apparatus includes a support member having a first or forward slot and a second or rearward slot. Each slot has a pin-support portion with a clearance region therebetween. The clearance region has first and second boundaries, the second slot includes a pivot portion and the pivot portion and the first boundary define a second spacing dimension slightly greater than the first spacing dimension. The combination is adaptable to a wide variety of shelf types and has particular utility when used in a store fixture for retail display of articles offered for sale.

Abstract: A merchandise display rack has compartments for displaying products. Each such compartment has a rear panel, a front panel and a follower with a first panel portion mounted for movement toward the front panel when a product is removed from the compartment. The first panel portion and the front panel substantially abut one another when the compartment is emptied of products and the first panel portion and the rear panel substantially abut one another when the compartment is filled with products. The follower is guided along the bottom panel by a guide member which extends from the follower into a slot in the bottom panel. Such guide member has a mechanism for modifying its width to compensate for slot/guide member wear. Vertically adjacent compartments are staggered so that substantially the entirety of at least the lower compartment is readily visible.

Abstract: The improved system is used for mounting a panel such as a sheet of dry wall or a plywood panel in a wall-like display structure of the type supporting wall panels having exposed exterior surfaces. The system includes a pair of studs such as sheet metal studs. Each stud has a flange surface (the narrow-edge surface of the stud) which is substantially coplanar with the flange surface of the other stud. A pair of upright members is interposed between the studs and each upright member includes a lip extending generally parallel to a stud flange surface. Several spring clips are attached to each lip and each clip includes an opening receiving a panel edge. Panels are thereby retained by the clips on the upright members.

Abstract: The invention is an improvement in a modular wall system of the type having a forward standard for attaching a merchandising display thereto. Such system also has a rearward pair of laterally-extending flanges, a web extending between each flange and the standard and at least one opening in each web for wall panel attachment. The improvement includes at least one (and preferably at least two) "slideby" brackets mounting a panel to a web. Each bracket has at least one tongue extending through the opening for slide-and-release panel mounting. The panel and attached bracket are thereby mounted or demounted without tools.

Abstract: The improved system is used for mounting a "wall standard," i.e., an elongate, slotted strip to which shelf support brackets are attached. The standard is in a wall-like display structure of the type having plural support studs. The improved system includes a box-like "filler" or spacer mounted between the studs. The spacer has at least one exposed edge used to attach a retention assembly for holding panels to the wall "skeleton." The assembly includes a pair of upright members which are commonly-shaped but mounted in inverted "mirror image" relationship one to the other. Such upright members each have several spaced tabs, each of which is "interposed" between tabs of the other upright member. Tabs of both upright members are attached to the first edge for panel support. Using commonly-shaped, inverted-mounted upright members increases installation flexibility and reduces parts inventory. Certain system features accommodate wall panels of differing thickness and mount panels for quick attachment and removal.
