Abstract: A quick coupler for connecting an implement to an arm of a machine. The quick coupler includes a frame having a first plate and a second plate. A first and a second pair of recesses provided on the first and the second plates at a first end and a second end of the frame, respectively. A cover plate disposed between the first and the second plates and one or more lubrication lines having fittings attached to terminal ends of the lubrication lines. An external lubrication bank provided on at least one of the first or the second plate to support the fittings.

Abstract: A modular crankshaft features a connection system between modules that features opposed female receptacles. A pin having opposed beveled ends and hydraulic passages with it is inserted into the opposed receptacles. A pair of seals is disposed on the beveled ends and straddles a hydraulic fluid outlet. The crankshaft wall that defines each receptacle is designed to flex in response to applied hydraulic pressure between the seals on the tapered pin portion. A notch at the base of the receptacle in the crankshaft reduces stress concentration and enables the wall defining the crankshaft receptacle to come back when hydraulic pressure through the pin is removed. The opposed crankshaft receptacles are flanged to allow them to be pulled together over the pin. An interference fit results around the pin after the flanges are mated and the hydraulic pressure is removed.

Abstract: A knuckle-swivel (10) is used with well drilling equipment for protecting helical wound line 62, which may be wire rope, cable and/or strand, against torsional forces and also providing for angular displacement of sinker bars or other tools during wireline strip over operations to minimize interference with rig equipment (80) when pulling pipe or tools 64 from a well head.

Abstract: A clamping mechanism comprises a first clamp half 20 and a second clamp half 22. The first clamp half 20 and the second clamp half 22 contact a linear guide rail 14 at one end thereof and a key 12 at another end thereof, with the key 12 being coupled to the moving member. A plurality of threaded shafts 40 pass through both the first clamp half 20 and the second clamp half 22 while also passing between the linear guide rail 14 and the key 12. A plurality of cooperating nuts 42, 44 are provided on each end of the threaded shafts 40 to secure the first clamp half 20, the second clamp half 22, the linear guide rail 14 and the key 12. When the user desires to alter the position of the moving member relative to the guide rail 14, the user actuates a plurality of pistons 24 located within the clamping mechanism.

Abstract: A hydraulic connector assembly is provided to couple an extension rod to a piston rod in a reciprocating pump. The connector assembly utilizes a single hydraulic ram to provide the compressive connecting force between the two rods. The connector assembly includes a mechanism for mechanically locking the hydraulic ram in place so that loss of hydraulic power does not uncouple the assembly. The piston rod and the connector rod can be coupled and uncoupled without the use of heavy wrenches, hammers, or impact tools.

Abstract: The invention is a ring-like lubrication device used in a pivot joint of the type connecting two members such as on an articulated agricultural tractor or wheeled loader. Such joint has a joint pin and a bearing permitting relative oscillating and articulating movement of the members one to the other. The device includes a hollow, annular reservoir-like chamber which holds lubricant for the joint/bearing sliding surfaces. The device also seals the joint to obstruct the entry of dirt. In a highly preferred arrangement, a device is mounted at the top and bottom of a joint for lubrication and obstruction of dirt entry. The device is configured and arranged to accommodate oscillating and articulating movement between the joined members.

Abstract: Improved fence bracing members, and a method of using the bracing members on metal T-posts of a fence. The bracing members include two substantially identical elongated first members each made of corrosion resistant tubing, and further having somewhat flexible U-shaped or hooked oppositely disposed ends. Each hooked end of the first bracing members is apertured to receive a single bolt to allow the compressing of the hook onto a T-post. The first bracing members are structured for spanning horizontally between, and attaching with the hooked portions placed around a T-post. One first bracing member is placed adjacent the ground, and one first bracing member is placed adjacent the upper ends of the T-posts.

Abstract: A grating mat assembly is disclosed, which is of a generally rigid construction, as distinguished from an articulated, roll-up construction. Unlike conventional rigid grating mats, the structure of the present invention comprises a plurality of slot-like section joined edge to edge in a manner providing for sufficiently rigidity for manufacture, handling and installation, while eliminating the customary longitudinally extending locking bars, utilized in more conventional grating mat assemblies, which add significantly to the cost of manufacture thereof. The slot-like mat sections of the new design are of extruded construction, formed with a horizontal upper ball, widely spaced vertical end walls, and one or more intermediate vertical walls. The vertical walls support the upper wall substantially above a base surface. The opposite vertical end walls of the slot-like sections are formed with tongue and groove structures, such that a pair of adjacent section interfit to provide positive horizontal alignment.

Abstract: A slat fence retainer for retaining slats in a chain-link fence includes a horizontally disposed slat-retaining element having a pair of spaced apart side walls, a base joining the bottom margin of the side walls and an open top. The element includes a vertical-slat retention means thereon. Plural, vertical slat elements are predimensioned to be received in the links in the fence. Each vertical slat element has at least one substantially planar and resilient flange at an end thereof and slots formed adjacent the end for engagement with the slat retention means to hold the vertical slat element in the fence.

Abstract: A hydraulically operated disk brake apparatus for a motor vehicle comprises a brake disk, a caliper-like brake housing disposed to straddle over the brake disk and having a pair of arms, and a pair of brake pad assemblies disposed in the brake housing in opposition to each other with the brake disk being interposed therebetween. The brake pad assemblies are movable toward and from the brake disk. A cylinder chamber is formed in one of the caliper arms and accommodates therein a first piston for pressing the adjacent brake pad assembly to the brake disk and a second piston positioned with a distance from the first piston. The second piston is operated by an externally provided actuator member to produce a hydraulic pressure in the cylinder chamber for moving the first piston and the associated brake pad assembly toward the brake disk. A reservoir for hydraulic fluid is formed in the brake housing to supply supplementary fluid into the cylinder chamber.
