An apparatus is disclosed for aiding in the speed and simplicity of the adjustment of the clicker-style cam bolts employed by TRA-type snowmobile drive clutches, manufactured by Bombardier Recreational Products. The apparatus comprises a barrel type nut with a collared head and a compression wire spring which fits telescopically over said nut and against said collared head, and a locking set screw to secure the apparatus against rotational movement or removal. This assembly replaces the conventional hexagonal lock nut presently used on TRA-type drive clutches. This apparatus enables the user to change the linear position of the cam bolt in the drive clutch housing to enable the hexagonal head of the clicker-style bolt to clear its respective hexagonally indexed pocket, which is molded into the drive clutch housing, and to be turned to any one of six different degrees of rotation, thereby changing the shift-out RPM setting of the drive clutch quickly and with greater ease than conventional methods. |

A method of making a shaft abutment screw, especially for axial engagement with an armature shaft of an electric motor, includes the following steps:(a) pressing out a flat mild steel blank, (b) subjecting the blank to a drawing operation so as to form a hollow component comprising a generally flat radial base wall and a generally cylindrical skirt portion extending from the base wall and describing a screw driving socket within it, (c) machining a screw thread on the outside of the skirt portion, and then (d) nitriding the component. A shaft abutment screw having a flat base portion joined to an externally threaded cylindrical skirt portion, within which a hexagonal screw driving socket is formed, is also described per se. The invention is applicable especially to motorised reduction gear units for driving motor vehicle screen wipers for windshields and rear windows. |

A method for assembling a substantial barrier to the flow of liquid in a circumferentially-extending liquid conduit groove of a mold insert includes forming recesses or undercuts by undercutting the sidewalls of the liquid conduit groove, inserting a plate-like liquid dam within the liquid conduit groove, and clamping the dam in the liquid conduit groove by the use of a pair of locking screws or pins that extend through bores in the dam into engagement with inwardly-facing surfaces of the undercuts. The relationship between the inwardly-facing undercut surfaces and the locking members is preferably such that there is a progressively increasing interfering engagement of the locking members with the undercut surfaces resulting in increasing clamping pressures applied to the dam assemblies. |

The present invention relates to a compressible screw-type locking mechanism including an oversized locking screw and a tool for compressing and rotatively driving the oversized locking screw through a threaded bore. Formed about the top of the locking screw is a head portion and extending downwardly from the head portion is a threaded shaft. At least one longitudinal slot extends through the head and at least partially through the shaft to form a locking screw with plural resilient segments. The locking screw assumes a normal expanded state with its threaded pitch diameter being oversized with respect to its companion bore. The locking screw is compressed by engaging the head thereof with the tool. In one embodiment, the compression of the locking screw is achieved through a torquing action. In a second embodiment, the compression is achieved by the axial movement of the tool. In either case by relieving the applied torque or removing the tool from the locking screw head results in the locking screw expanding within the bore and assuming an interference or locked fit within the bore. |
