  • Patent number: 11298172
    Abstract: Instruments for applying tension to a securing device, such as a cable or wire, for securing bones in place and fastening implants, such as plates, to bones. In some forms, the tensioning instrument is configured with minimal parts for ease of manufacturing and allowing single use applications. The instrument may include a pretensioning mechanism for applying desired preload before connecting a cable to be tensioned to the instrument. The instrument may be sized and configured to remain attached to a tensioned cable while other cables are connected to a bone. In another form, the instrument may be expandable to remove any slack from the securing device and apply tension thereto.

    Abstract: A brush clearing assembly includes a mounting unit that may be coupled to a tractor. A hooking unit may be coupled to the tractor thereby facilitating the tractor to draw the hooking unit. The hooking unit is movably coupled to the mounting unit. The hooking unit may engage a trunk of a bush when the tractor backs toward the bush. The hooking unit slides laterally in the mounting unit when the hooking unit engages the trunk of the bush. Thus, the hooking unit slides along the trunk of the bush until the hooking unit passes beyond the trunk of the bush. The hooking unit removes the bush when the tractor drives forwardly from the bush.

  • Patent number: 6068318
    Abstract: There is a clamp for a conveyor belt. The clamp comprises a yoke having a shoulder member, two laterally extending arms defining a recess therebetween and a channel which extends through the yoke at a right angle to the width of the recess. In use of the clamp an edge portion of the belt is located in the recess and a pair of beams are inserted through the channel to pass respectively over and under the belt and rotation of a turn-screw extending through a threaded seat in one of the arms exerts a clamping force through the beams directly onto the edge portion of the belt.

  • Patent number: 5988595
    Abstract: A method and apparatus for transferring a weight of chain link mesh fence and holding the fence in position while a single installer secures the fence. The apparatus includes a lever arm, at least one tip for engaging an intersection of chain link mesh, a pivot point between the lever arm and tip, a hook attached to the lever arm by a flexible tether or connector which allows the chain link mesh to remain in place once engaged. The installer first places the pivot point on the fence post and pivots the chain link mesh upward to the desired height. Then the installer attaches the hook to an intersection of fence so that the flexible tether is taut. Once done, the forces are balanced on each side of the pivot point of the apparatus and the installer can release the tool and work with both hands to install the fence.

  • Patent number: 5931447
    Abstract: In order to provide a simple and inexpensive laying aid for floor covering elements, in particular ready-made parquet flooring, laminated or floor panels, it is suggested that the laying aid be designed in the form of a belt tensioning device with a belt and have a shaped part on both sides, that each shaped part have a receiving means for the belt, that each shaped part have an arm with a projection which can be fixed at a groove or a tongue of the floor covering elements by engaging in it and around it, respectively, and that when the arm is fixed in such a manner the receiving means be positioned such that the belt is guided by this close to the floor covering elements.

  • Patent number: 5800123
    Abstract: An apparatus for tensioning a subsurface float line and the like during doyment of the line and thereafter includes a capstan rotatably mounted and located in a liquid medium, the capstan having a bore extending from one end of the capstan to the other end, the bore including a plurality of pump blades for moving the liquid through the bore when the capstan is rotated, the capstan also including turbine blades located around the circumference of the capstan and adjacent both ends of the capstan, the capstan also including a circular surface interposed between the turbine blades for communicating with the line to be tensioned. The pump and turbine blades do work when the capstan is rotated thereby creating a counter rotational (drag) force that tensions the line during and after deployment.

  • Patent number: 5788697
    Abstract: A cable tensioning device comprises tubular shaft having an outer threaded portion, and a handle member surrounding a portion of the shaft, with the shaft and handle member being connected in screw-threaded relation. The shaft moves longitudinally relative to the handle as the handle rotates, driven by the screw threaded connection. A gripping member is carried on the shaft distal to the handle member for holding a replaceable bit, which, in turn, may carry a cable crimp. A cable lock is positioned typically proximal of the handle member to hold the ends of cables extending through the tubular shaft. Rotation of the handle member can cause the shaft to move longitudinally to lengthen the distance between the cable lock and a crimp held by a bit which, in turn, is held by the gripping member, to impose a tension on the cable. A meter is present for measuring the amount of tension applied to the cable.

  • Patent number: 5725269
    Abstract: A portable belt clamping and pulling apparatus is provided to grip and pull belt ends together for splicing belt ends of a conveyor belt. A pair of belt ends are clamped between respective pairs of I-beams, the clamped belt ends are pulled together by a come-along mechanism, and the free ends of belt between the I-beams are maintained held together in a tension-free environment to allow fastening together of the belt ends. The preferred clamping jaws are in the form of at least one clamping lever pivotally mounted on a central frame having a central opening through which the I-beams are inserted. The clamping lever is connected to a pulling device that pivots the clamping lever to cause the clamping members to tightly grip a belt end between the I-beams. The clamping jaws include respective pre-tightening screws for clamping the I-beams to the belt prior to the initiation of pulling by the chains so as to eliminate slippage of the belt from between the I-beams during the initial pulling.

  • Patent number: 5597151
    Abstract: A stake puller (10) for use in removing a stake (4) lodged in the ground (2) utilizes a lever (12) and fulcrum (20) for mechanical advantage. The stake (4) is positioned between a blade means (30) fixed to the end of the lever and a back plate (40) pivotally attached to the blade means. When the user pivots the lever down, the stake is pinched between the forward edge (34) of the blade means (30) and the primary surface (42) of the back plate (40). The primary surface (42) is curved and diverges from the stake. This minimizes any bending or friction forces applied to the stake.
