A tool assembly having a pair of jaws is disclosed. Each of the jaws has a proximal end and a distal end and the first jaw is movable in relation to the second jaw between a spaced position and an approximated position. First and second cam followers are supported on the first jaw. An approximation member is movable in relation to the first jaw and includes at least one cam surface positioned to engage the first and second cam followers. The approximation member is movable in relation to the first jaw to move the at least one cam surface in relation to the first and second cam followers to effect movement of the first and second jaws from the spaced position to the approximated position. The at least one cam channel is configured to approximate the distal ends of the first and second jaws prior to approximation of the proximal ends of the first and second jaws. In another preferred embodiment, the tool assembly includes an articulation and firing actuator. The articulation and firing actuator includes a flexible band having a first end portion extending at least partially through the body portion and through the cartridge assembly, a central portion extending from the first end portion operably associated with the dynamic clamping member and a second end portion extending from the central portion through the cartridge assembly and at least partially through the body portion to a position adjacent the first end. The articulation and firing actuator is operably associated with the tool assembly such that movement of either the first end portion or the second end portion of the flexible band proximally and independently of the other end portion effects pivoting of the tool assembly in relation to the body portion, and movement of both the first and second end portions of the flexible band simultaneously effects movement of the dynamic clamping member to eject the staples from the cartridge assembly.

A sharps container for safe reception and storage of used pen needles and used medical syringes comprises a housing which supports a manually rotatable member. A used pen needle receiving and ejecting apparatus is connected to the rotatable member. Used pen needles are inserted into the receiving apparatus. As the receiving and ejecting apparatus is rotated, a cam follower connected to the ejecting apparatus engages a cam within the housing to cause the ejection of the used pen needle from the receiving apparatus into the housing. The rotatable member also has an elongated recess sized to receive a medical syringe. Manual rotation of the rotatable member rotates the elongated recess to drop the medical syringe into the housing.

An imaging apparatus includes a printhead carrier for mounting a printhead cartridge. The printhead carrier includes a carrier back wall having an upper portion. A back portion of a printhead cartridge cradle is connected to the carrier back wall. A first proximal end of a latch lever is pivotably attached to a front portion of the printhead cartridge cradle. The latch lever has at least one cam follower, with each cam follower being located near the first distal end of the latch lever. A second proximal end of a carrier lid is pivotably attached to the upper portion of the carrier back wall. Each cam of the carrier lid is formed near a second distal end of the carrier lid, and each cam is positioned for progressive engagement by a corresponding cam follower as the latch lever is moved from an open position toward a latched position.

Disclosed are crankshaft, single-plate cam and beam mechanisms that provide significant improvements in performance for 2- & 4-stroke engines, compressors and pumps. These cost effective mechanisms include linkages with the new and improved use of pivoting arms that operate with a variety of cylinder arrangements. One embodiment of the crankshaft mechanism has its crankpin roller positioned within a novel yoke-arm. The cam mechanism uses a pair of centrally positioned parallel links that are connected to roller cam followers and single or diametrically-opposed pistons. A pair of laterally extending follower arms connects to the ends of the links to provide support and alignment for the piston rods. Between the reciprocating links, cam followers and follower arms is a rotating odd-lobe plate cam. A beam mechanism uses opposite-direction extending balancing beams that are connected to links, cam followers and piston rods.

A quick adjust ratcheting pocket hole jig is presented. The pocket hole jig has a base with a removable upright connected thereto. A guide assembly is slidably received within the upright. Removable and replaceable side supports are connected to the base by way of a dove tail joint. Removable and replaceable adjustable stops are connected to the base by way of key holes. A clamp assembly is connected to the base having a handle portion and a clamp follower. The clamp follower has a ratcheting mechanism and a compressible plunger assembly. The clamp follower can quickly be adjusted using a button on the clamp follower that disengages the ratcheting member such that it can be quickly adjusted. When the handle is operated, it draws the clamp follower towards the upright and guide assembly compressing the spring loaded plunger assembly thereby quickly and tightly and adjustably holding a workpiece therebetween.

A hinge assembly includes a housing (1) encasing a spring (2), a cam follower (3), a cam member (4) and a washer (5) therein. The cam follower has a shaft (31), and a pair of tabs (32) perpendicularly formed on the shaft. The spring is coiled over the shaft, and is compressively engaged in the housing. The tabs of the cam follower slide in grooves (13) of the housing. The cam member includes a cam portion (43) and a connector (41). The cam portion forms a pair of peaks (46) and a pair of valleys (44), being engaged with the tabs of the cam follower. The connector extends outside of the housing. The washer is rotatably inserted over the connector, and is fitted in the housing for fixing the hinge components in the housing.

A cam powered mechanism which uses two cam forms, a swing arm, and turret to drive an output shaft with a compound radial and axial movement. An arrangement in which a cam follower is positioned opposite each planar surface of the rectangular spline connecting the turret and output shaft acts to increase turret strength and reduces the size of the mechanism.

A shower assembly is provided that includes a shower head having an integrated diverter valve. The shower head receives a detachable hand-held shower wand. The diverter valve is arranged upstream of an adjustable connector so that length is not added to the shower assembly that would interfere with headroom. A cam shaft of the diverter valve is rotated to selectively control fluid flow between the shower head and the hand-held shower wand. Cam followers are moved linearly in response to rotation of the cam shaft to selectively block first and second outlet ports.
