A force transmitting member may be mounted for linear reciprocable movement inside the chamber under the action of external loads. An axial array of plates is floatingly disposed in the chamber between the force transmitting member and an end wall of the chamber. At rest, each plate is spaced from an adjacent plate by a gap occupied by the working fluid. When the force transmitting member is displaced towards the array of plates, the fluid in the chamber causes the plates to be successively pushed against each other, thereby causing some of the fluid to be squeezed out from between the plates.

    Abstract: A power tong continuously rotates tubulars for spinning and torquing threaded connections. Continuous rotation is achieved through a rotating jaw having grippers that grip the tubular and continuously rotate with it. Hydraulic and electrical power necessary for actuating the grippers is generated on board. A serpentine belt system turns the motors of the on-board hydraulic power unit and electric generators to supply the grippers with hydraulic and electrical power. The serpentine belt system is driven by a secondary drive mounted on a fixed frame. The rotating jaw is rotatably mounted to the fixed frame and driven during continuous three hundred and sixty degrees of rotation by a primary drive, mounted on the fixed frame. A fixed jaw is also mounted to the frame. Tubular grippers on the fixed jaw grip a first side of a tubular joint. The grippers on the rotating jaw grip the opposite second side of the tubular joint. High torque low-rotational speed applied to the rotating jaw torques the joint.

The hand grip may include a lip at a lower end thereof, such that a pinky finger of the hand may be comfortably placed on either side of the lip while the hand grasps the hand grip. The resilient material construction of the handle permits a first end of the handle to flex slightly towards and away from the second end of the handle. Accordingly, during use, the striking tool provides a damped recoil and improved striking action, imparting less shock to the hand, wrist, elbow, shoulder, and other parts of the body, as compared to a conventional striking tool.

  • Publication number: 20080302214
    Abstract: A striking tool is disclosed that comprises a generally U-shaped or V-shaped handle constructed of a substantially resilient material and having a head fixed at one end thereof. A second end of the handle has a hand grip or gripping region adapted to be grasped by a human hand. The second end of the U-shaped or V-shaped handle includes a flange, or stop member, to inhibit the handle from slipping out of the grasping hand. The hand grip may include a lip at a lower end thereof, such that a pinky finger of the hand may be comfortably placed on either side of the lip while the hand grasps the hand grip. The resilient material construction of the handle permits a first end of the handle to flex slightly towards and away from the second end of the handle. Accordingly, during use, the striking tool provides a damped recoil and improved striking action, imparting less shock to the hand, wrist, elbow, shoulder, and other parts of the body, as compared to a conventional striking tool.

  • Patent number: 7448299
    Abstract: A hand tool with vibration-damping sleeve is provided. The vibration-damping sleeve is set between a hammering body and a handle of the tool to buffer the hand tool from vibrating. The vibration-damping sleeve is wrapped around and joined with the handle of the hand tool by injection molding and is set in the through hole of the hammering body. Thus, the vibration-damping sleeve is tightly connected to the hammering body, thereby blocking the vibration transmission at hammering. The sleeve is made of a hard PP plastic slightly in the form of an awl, one end of which is sealed and the other end is open; the front exterior wall is divided into upper and lower caves and two convex sides.

  • Patent number: 7320266
    Abstract: Shock dampener incorporated into a hammer handle. Using a counter weight attached with a hinge pin to provide extreme shock dampening when striking solid objects with a hammer tool. Shock travels in waves known as vibration. When striking an object with the hammer's head, a shock wave is created and travels down the handle. The shock wave travels through the whole hammer handle at one time in an instant. This allows for energy of the shock to transfer into the counterbalance dampener hinge pin and vibrate the dampening member that is buffered with a form of rubber diffusing 95% of the shock energy with the dampening member.
