    摘要： In a dual camshaft structure, an inner shaft provided with a variable cam is inserted into an outer shaft provided with a secured cam. In the dual camshaft structure, the secured cam is provided on a first cylindrical member, the first cylindrical member is secured to the outside of the outer shaft, the variable cam is provided on the second cylindrical member, and the second cylindrical member is installed at the outside of the first cylindrical member and is secured to the inner shaft by a connection member via a notch provided on the first cylindrical member and a notch provided on the outer shaft. Therefore, the rigidity of the dual camshaft structure can be ensured, and a slidable surface of a cam rotatable at the outside of the outer shaft can be held.

    摘要： A mechanical timer to control multiple steps of a process comprising a first cam having a shaft, and a second cam having a shaft, wherein the shaft on the first cam extends into the shaft of the second cam. The rotational relationship between the first and second cams determines the length of time for at least one process step. First and second user adjustable elements are attached to the first and second cams. These user adjustable elements do not require any disassembly of the mechanical timer by the user or require any tools. A plurality of switches engage the cams to control various process steps.

    摘要： An actuating apparatus, which can be used to perform variable valve timing of the intake or exhaust valves of an internal combustion engine, includes a hollow shaft with at least one slot defined through a cylindrical wall. A movable cam member is disposed to project through the slot and is rotatable relative to the hollow shaft in a channel defined in the interior surface of the hollow shaft. A base circle band extends circumferentially around the outer surface of the hollow shaft between the endwalls of the slot. The exterior surface of the hollow shaft can define grooves which receive front or back ear members of the cam member. The exterior surface of the hollow shaft also can define recesses, which in some embodiments have bottom surfaces and in other embodiments have partial bottom surfaces or no bottom surface. The recesses can receive tongue members formed on the cam member. The cam member can be engaged by a cam follower that has a roller to engage the cam surface. When the length of the roller exceeds the width of the cam surface, base circle arcuate sections can be provided on the exterior surface of the hollow shaft to carry the roller across the exposed portion of the slot that exists between the endwall of the slot and the free end of the cam member. An inner shaft extends through an opening defined transversely through the cam member and nonrotatably engages same. The nose portion of the cam member can be defined by a rotatable roller. Twin cam members having identical cam surface profiles can be disposed side-by-side, with one cam member projecting through the slot and the other cam member secured to the outer surface of the hollow shaft. A single follower such as a tappet defining a circular cylindrical surface can be provided to engage both cam members and can be held nonrotatably.

    摘要： A camming system for a copier machine for providing multiple paths for a cam follower from a start of scan position. The camming system includes a cam, a cam follower, and a drive to drive the cam follower to and from a start of scan position while in contact with the cam. The cam is adapted to be rotated about the center of curvature of the cam follower axis during rotation of the cam so that the cam follower always starts its path from the same start of scan position.

    摘要： A time variable apparatus for controlling a valve. A first and second cam are mounted to a shaft rotatably driven adjacent to a piston which extends outwardly from a frame adjacent to the cams. One cam is operable to force the piston head to a first position whereat a spring biased latch secures the piston in the first position. The second cam is operable to release the latch thereby allowing the piston to move to a second position. The second cam is slotted and receives a fastener extending outwardly from the first cam. The fastener may be loosened so as to adjust the relative rotational positions of the second cam with respect to the first cam thereby allowing for adjustment and control of the duration during which the piston is in either position.
