20090000095 | SPIRAL SPRING RETENTION WRENCH - A spiral spring retention wrench for removing a cable-retaining bolt from a sliding throttle valve of a carburetor. The wrench comprises a disk-like body having two, flat, opposed surfaces and a circumscribing peripheral edge extending between the surfaces. A depression, having a circular periphery is centered on one surface of the body. The diameter of the depression is such as to receive an end of the spring and hold that end during use of the wrench to remove the bolt. On the other surface of the body a centrally disposed depression for receiving a head of the cable retaining bolt in a manner so as to grip the bolt head and act on it either to release or tighten the bolt when the wrench is rotated. | 01-01-2009 |
20090013514 | Strut spring compression apparatus - A spring-compression apparatus for facilitating maintenance of a strut assembly comprises a guide member, a carriage assembly, and a spring-channeling assembly. The guide member comprises a first member end and a second member end. The carriage assembly comprises a jack assembly and a slide assembly. The jack assembly is operable to otherwise displace the slide assembly along the guide member. The slide assembly comprises a locator assembly, which comprises a locator extension arm and a pivotable strut end interface. A strut spring is receivable in the spring channeling assembly as laterally engaged therewith. The strut end interface is engageable with a strut end for compressing the strut spring. The locator assembly further enables a user to remove a mounting nut from the interface-engaged end when the strut spring is compressed, thus enabling strut assembly disassembly. | 01-15-2009 |
20110314649 | SYSTEM AND METHOD FOR GARAGE DOOR COUNTERBALANCE - A tool for use in installation, adjustment and removal of an energy storage device for a counterbalance system. The tool includes a member rotatable to manipulate a spring carriage. One embodiment includes a threaded shaft, an engagement member which engages the slidable carriage, a locking nut disposed on the threaded shaft, and a bearing member disposed to the threaded shaft between the locking nut and the engagement member. A position of the slidable carriage between compressed and extended positions relative the track housing is adjustable by rotation of the threaded shaft. Another embodiment includes a frame, a cable spool rotatably attached to the frame, and having a gear attached in a co-axial arrangement to the cable spool, and a worm gear attached to the frame. The spool gear is rotatable by the worm gear to apply axial force to the slidable carriage by winding the counterbalance cable. | 12-29-2011 |

20120291244 | Jig for Mounting a Stack of Belleville Springs - The invention relates to mounting of a stack of Belleville springs about a shaft. The individual springs of the stack are first positioned over the shaft. A jig is then placed over the shaft and the springs and has at least one axially extending pressure bar that is radially inwardly biased to urge the inner circumferences of all the springs into contact with axially aligned points on the surface of the shaft. The springs are then compressed using a compression element while they are still urged by the pressure bar against the shaft. Finally, to retain the springs on the shaft and maintain the springs in compression, a split retaining clip is pressed onto to the shaft until it engages in a groove. | 11-22-2012 |
20130255050 | TOOL FOR ASSEMBLING A SECURING RING - The invention relates to a tool for assembling a securing ring. The tool comprises two adjusting limbs which are connected to each other in a rotary joint and each free end of which has gripping means for engaging into an assembly opening of the securing ring. The tool further comprises a spindle drive provided between the adjusting limbs for changing the distance between the adjusting limbs. According to the invention, the rotary joint is arranged on the adjusting limb ends opposite the free ends, and the spindle drive is arranged between the rotary joint and the free ends of the adjusting limbs. | 10-03-2013 |
20150013128 | Snap ring pliers - The present invention relates to a snap ring pliers. As to the entire structure of the present invention, a lock member is simply turned to control gripping members to hold or release deformation of a snap ring. The lock member is turned for a stop of a limit member to hold against the upper surface of an elastic plate to block a hook portion from moving upward, so that the elastic plate can be made with a thinner plate. The hook portion is flexibly held by teeth of a ratchet rail. A lower protrusion of the elastic plate is held by an upper protrusion of the lock member with less resistance. This enhances the lock member to be turned in a labor-saving or flexible way. | 01-15-2015 |
