  • Patent number: 6351881
    Abstract: A hinge pin removal and starter device is disclosed, comprising a bar portion having a first and second end portion. The first end portion of said bar tapers to a flattened tip having a concave edge. A cylindrical projection adjacent the opposite butt end protrudes from said second end portion a generally perpendicular direction thereto. The tip of said first end portion is adapted for forcible insertion between the head of a hinge pin and a hinge, to wedge the hinge pin and hinge apart and detach said pin from said hinge plate. The cylindrical projection adjacent said second end portion is adapted to be placed in abutting relation to said pin opposite the head of said pin and a force applied against the pin through the cylindrical projection, to at least partially displace said pin from the hinge plate into which the pin is inserted.

  • Patent number: 6341763
    Abstract: A lever-action vehicle lift for lifting a from the ground surface. The lift frame defines a vehicle contacting section and a fulcrum section for rotatably supporting the lever frame when the latter is pivoted about the ground surface. A spacing section is solidly attached between the vehicle contacting section and the fulcrum section for maintaining the vehicle contacting section and the fulcrum section in a first predetermined spaced relationship relative to each other. The vehicle contacting section and the fulcrum section are positioned in a common geometrical plane. A lever handle is pivotally attached to the lever frame by a handle pivotal connection so as to allow the lever handle to pivot about a lever pivoting axis extending in the common geometrical plane.

  • Patent number: 6302378
    Abstract: A new snowmobile jack that does not require the hands or fingers of the user to be anywhere near the jack when raising and lowering the snowmobile. The jack comprises a T-bar that moves telescopically vertically to support a rear handle/tow bar on a snowmobile. A mechanical linkage operated by a first foot pedal raises and lowers the T-bar. A second mechanical device on the jack includes a positive latch operated by a second foot pedal. The latch positively prevents the first foot pedal and linkage from lowering the T-bar. Both foot pedals must be simultaneously depressed to release the latch and allow the T-bar to descend. The simultaneous action with two feet makes very unlikely any inadvertent lowering of the jack and obviates the need for the user to reach down to the jack with the hands.

  • Patent number: 6202985
    Abstract: A tool for lifting and removing heavy lids, such as manhole covers and similar articles. The tool includes an elongate lever with a handgrip at the upper end and a pivot head at the lower end. Wheels on the pivot head provide a pivot axis, with a hook being mounted in front of the pivot axis and a footplate being mounted behind the axis. The hook is inserted in an opening in the lid, and the lid is then lifted and removed by pulling back on the lever and stepping down on the footplate. After removal, the lid can be transported by rolling the assembly over the ground using the wheels. The invention thus facilitates removal and installation of heavy lids with minimal strain and potential injury to the operator.

The first such method includes the steps of establishing a fulcrum on a floor a predetermined distance from the wall, placing a lever in contact with the floor fulcrum, placing a push bar between the lever and the wall, and pushing against the lever towards the wall, whereby the push bar pushes the wall away from the lever. The second or alternate such method of adjusting orientation of a wall includes the steps of establishing a fulcrum on a floor a predetermined distance from the wall, placing a lever in contact with the floor fulcrum, connecting one end of a flexible line assembly to the lever and connecting the other end of the flexible line assembly to the wall, pulling the lever away from the wall, whereby the flexible line assembly pulls the wall towards the lever.

  • Patent number: 5832581
    Abstract: A tool for lifting the fork rod of a diesel engine for ready replacement of a fork blade. The lifting tool includes a base having an upper arcuate edge for engagement with a maintenance manhole of the diesel engine. A fulcrum plate projects from the base and has a bore formed therethrough. A two-shafted lifting arm has a complementary bore for pivotal movement with respect to the base by insertion of a fulcrum shaft through the aligned bores. A handle is insertable into one of the shafts, and a fork into the other. The fork includes a fork head having a pair of spaced apart tongs including means for engagement with the fork rod. By depressing the handle, the fork arm may be pivoted into a raised position, thus lifting the fork rod when it is engaged with the tongs. Means are also provided for fixing the fork head into the raised position.

  • Patent number: 5826857
    Abstract: A commercial mower support stand includes a cradle at its top that is adapted to engage a lifting bar that is secured to the front or rear end of a lawn mower, golf cart, or other light vehicle. The cradle is supported by a plurality of upstanding rigid legs that are secured at their respective lowermost ends to a base plate. A pair of laterally spaced apart support legs support a forward end of the base plate and a pair of laterally spaced apart wheels support the rearward end of the base plate when the stand is in its upright position on a support surface. A tube mounted at a predetermined angle to the base plate slidingly receives an elongate leverage handle that is used to manipulate the stand as needed when lifting and lowering a preselected end of a light vehicle. The stand includes storage receptacles for the leverage handle, replacement mower blades, a lubrication gun, or other items and tools.

  • Patent number: 5814842
    Abstract: A lift for positioning and supporting a work item vertically during installation while fastening devices are put in place includes a base member, a pivoting lever member supported by a pivot in the base member and a locking device for locking the lever member at a selected position. The lever member includes a pedal portion sized to receive a workboot of a worker. The locking device includes a jamming wedge received through an aperture in the lever member whereby concurrent bias by the workboot on the pedal portion and against the locking device raises the lever member and locks the lever member at the selected position. An alternative embodiment uses a pawl and ratchet assembly as the jamming wedge.
