Abstract: A sharpening system for a meat grinder is provided. The sharpening system embodies two types of sharpening stones for sharpening the cutting edges of the knife blade and the hole plate, respectively, of the meat grinder, wherein each type of sharpening stone operatively associates to the drive arbor of the meat grinder. By interchangeably replacing the knife blade along the drive arbor with one type of sharpening stone so as to sharpen and resurface the hole plate, or replacing the hole plate along the drive with the other type of sharpening stone to sharpen and resurface the knife blade, the present invention provides hands-free sharpening with no additional machines or tools.

Abstract: A platform for an order picker assembly is disclosed. The platform includes a frame assembly. The frame assembly includes a first support member and a second support member. The first and second support members are laterally spaced apart from one another and define a first axis therebetween. The platform also includes a support assembly coupled to the frame assembly. The support assembly includes a plurality of rollers. Each of the plurality of rollers is configured to rotate about a plurality of second axes. The support assembly also includes a plurality of support arms. The platform further includes at least one bar member extending between the first support member and the second support member. The platform further includes a pin element attached to the frame assembly, wherein the pin element has a circular cross section.

Abstract: A connector for a hand tool is provided. The connector includes a tool receiving portion configured to receive any one of a plurality of work tool pieces of the type having one of either at least a first or second locking configuration, wherein the first locking configuration is different at least in part from the second locking configuration. The connector also includes a locking mechanism coupled to the tool receiving portion and adapted to selectively couple any one of the plurality of work tool pieces to the connector.

Abstract: A device (20) for orienting a work tool (10) at a predetermined attitude relative to a work piece includes a base (22) having a first surface (34 or 44) abuttable against a work piece, a sleeve (24) coupled to the base, and a shaft (26) slidably receivable within the sleeve. The shaft has a first end portion (80) and a second end portion (82), wherein the first end portion is connectable to a work tool and the second end portion is connectable to an actuator for actuating the work tool.

Abstract: A fastener driver (20) is provided. The fastener driver includes a driver body (32) and a guide (26). The driver body includes a cavity (30) formed in one end of the driver body and an attachment shank (32) formed in another end. The guide is slidably attached to the driver body and is positioned for selectively retaining a fastener within the cavity during use of the fastener driver.

Abstract: An adjustable stop (20) includes an inner collar (22) and an outer collar (24). In one embodiment the inner collar has first and second inner collar contact surfaces (46, 50) in opposed disposition along a length of the inner collar. The outer collar is coupled to the inner collar and reciprocable between a locked position and first and second unlocked positions.

Abstract: A three-sided, rectilinear bridge or culvert structure comprises a pair of vertical sidewalls set in preformed or cast in place footers or existing supports and an integral, planar, horizontal span. The footers preferably include a sidewall receiving channel on their upper surfaces. There is no lower or bottom portion of the structure such as is found in conventional box culverts and thus, that region between the footers and sidewalls is open and readily permits water flow through the structure in its natural watercourse, lessening the likelihood of debris collection within the structure. The structure is cast concrete reinforced with conventional reinforcing bar or welded wire mesh. A wide range of rise/span (height/width) proportions may be accommodated in structures having spans up to about thirty feet.

Abstract: An apparatus for constructing an interlocked grid system which may be suspended from the main structure of a building for use as a ceiling panel support is disclosed in which transverse members interlock with suspendable support members. A tongue on each end of opposing transverse members communicates with a rectangular hole in the support member. The upper and lower edge of each tongue is deflected to form upper and lower shoulders which face backward toward the transverse member. Upon insertion of the tongue into the rectangular hole, the shoulders engage the support member at the upper and lower ends of the rectangular hole. The leading end of the tongue is wedged and maintained in position within the orifice by a centrally located reinforcement bead on the opposing transverse member. The reinforcement bead extends across the junction of the tongue with the transverse member to perform a reinforcing function as well as the wedging function.
