Abstract: A tool is provided for use in combination with a conventional claw hammer. The tool comprises an integral tool body having a sleeve for surrounding the cylindrical striker section of the hammer head. A support portion extends outwardly from the sleeve generally at right angles to the longitudinal axis of the sleeve and carries at its remote end a surface engaging curved portion for resting against the surface from which a nail is to be pulled and for acting as a fulcrum holding the hammer away from the surface to improve the direction of pull on a nail grasped by the claw of the claw hammer. The surface engaging portion at the end of the tool has an apex at one end including a sharpened claw for engaging a fully embedded nail. At the opposed end is provided an anvil surface which can be struck by the hammer to drive the apex into position to grasp a nail.

Abstract: A jack includes a base provided with a plurality of catch blocks, a lift arm pivotable relative to the base, and a safety member pivotally mounted on the lift arm to move therewith. Thus, when the lift arm is lifted, the first end of the safety member is locked on either one of the catch blocks of the base, so that the safety member is fixed by the base during upward movement of the lift arm so as to fix the lift arm, thereby preventing the lift arm from being lowered too quickly when the power supplied to the lift arm disappears accidentally due to malfunction so as to provide a safety effect.

Abstract: A weed puller for gathering weeds at the interstices between the weed foliage above the ground and the weed root below the ground includes a handle for being held by a standing operator at one end and supporting a body at the bottom distal end. The body defines two blunted prongs on either side of a central axis on the body extending away from the attachment to the handle through the body. The two prongs define therebetween a V-shaped gathering gap with blunted opposed V-shaped edges on either side of the axis. There is a second body portion including portions of the two prongs, the first portion being divided from the second portion along a bending axis normal to the central axis of the body. The second body portion includes portions of the two prongs bent upwardly and away towards the handle at an obtuse angle along the bending axis to form a weed pulling cradle area in the body.

Abstract: Disclosed is a jack lever, in which oil is pumped by piston (10) to move a cylinder (20) faster, vacuum being created at a lower portion of the cylinder (20) moving up, oil in an oil tank (101) being then flowed in the lower portion through an oil suction channel to make the cylinder move up faster. If the cylinder (20) moves upward to push up a work piece, load is exerted into the cylinder (20), so making the piston (10) pumping oil stronger, the oil opening a check ball (15a) mounted on a bypass channel (15) by the pumping and being supplied to the lower portion of the cylinder (20) to move the cylinder up. At this time, the cylinder (20) moves slower but increases ascending force, thus requiring small power to manipulate a jack lever (not shown) pumping the piston (10).

Abstract: A device for removing a clip pin from a jack utilizing a lever having a first portion, a second portion, and a fulcrum therebetween. The arm is linked to the fulcrum of the lever and extends outwardly to bear on the housing of the jack. A fastener holds the lever first portion to the clip pin of the jack such that movement of the second portion of the lever about the fulcrum removes the clip pin.

Abstract: A lift mechanism for a fifth wheel trailer tube and foot pad that is both functional and accessible. A tee handle is made with curved ends and a smooth finish, making it comfortable to grip when lowering or raising the foot pad assembly. A telescoping tube is hollow, allowing a cable to be guided through it and around a pully to an eye bolt that is attached to the foot pad. A cover is provided over the pully to keep the cable securly in the pully groove and direct it to the foot pad using the slotted cutouts in the cover. A main “L” shaped bracket allows the telescoping tube to be mounted at an angle, making it easier for operator reach.

Abstract: The current invention describes an automatically locking leg support system for portable water and fuel towers. The system automatically locks a wedge into a support leg to support a water tower, once the tower reaches the desired elevated position, and holds the support leg in the desired position. When the tank is to be lowered, the tower is emptied and a hydraulic system disengages the automatic locking device so that the tower can be lowered.

Abstract: A base (108) for supporting a pole puller (110) utilized to manipulate a pole (186) includes first and second bearing arms (112, 114) configured to rest on a surface (60) with the pole (186) located between the first and second bearing arms (112, 114). A cross member (128) interconnects the first and second bearing arms (112, 114) and a housing (138) extends from the cross member (128) into which the pole puller (110) is seated. A flexible member (62) coupled to a ram (174) of the pole puller (110) encircles the pole (186). An upward force (72) is imposed on the flexible member (62) via the ram (174) to extract the pole (186) from a fixed, upright position in the ground (60). The support provided by the base (108) prevents the pole puller (110) from kicking into the ground as the upward force (72) is imposed.
