Unitary switch mounting and actuating apparatus, particularly suitable for use on automatic conveyer systems, comprises a case having a back wall with an aperture formed therein and two spaced side walls. A shaft is pivotally mounted between the side walls opposite the aperture in the back wall. An externally threaded nipple is welded to the back wall over the aperture therein. A radial leg is fixed on the shaft and extends through the aperture and nipple to a contact foot. A radial arm is fixed on the shaft. A torsion spring surrounds the shaft and resiliently urges the leg and arm into the unactuated position. A platform welded to the case supports a switch with its actuation element aligned with the radial arm. Movement of the leg from its unactuated position moves the shaft angularly and swings the radial arm to depress the actuation element of the switch to change the condition of the switch. The apparatus is mounted on a conveyer by locating the nipple in a hole of the conveyer rail and tightening a nut on its threaded portion against the conveyer.

Conveyer load shunting apparatus having a housing with a main shaft equipped with a radial shunt bar extending over the conveyer to divert a load traveling on one conveyer to another. A lever on the main shaft is swung by a solenoid via a push-pull rod to swing the shunt bar from neutral to a shunting position. A spring biases the shunt bar to neutral and the solenoid armature extended. A horizontal rocker bar extends from the housing into the conveyer and has a radial leg equipped with a load engaging wheel. A spring and a radial switch bar on the rocker shaft biases the rocker shaft angularly to swing the wheel to a neutral position below the conveyer. A radial blocker arm on the rocker shaft has an end which is engageable with a peg on the lever of the main shaft to block the angular position of the main shaft with the shunt bar in shunt position. Thus the weight of the load holds the apparatus in shunt position with no strain on the solenoid. Upon the load moving off the wheel, the rocker shaft moves angularly to unclock the peg on the lever of the main shaft and the main shaft is spring biased to swing the shunt bar to neutral and move the armature to its extended position.

Apparatus for selectively by-passing, stopping, and releasing loads traveling on a conveyer having a case equipped with a stop arm and a stop lever on a pivotal stop shaft. The stop arm is swung to a stopping position above the conveyer to stop a load by pivotal movement of the stop shaft and stop lever in one direction and is swung to a non-stopping position not above the conveyer by pivotal movement of the stop shaft and stop lever in the other direction. A blocker leg is pivotally mounted at one end on the case and has an outer end engageable with the stop lever. When the stop arm, stop shaft, and stop lever are in their stopping position for the purpose of stopping a load, a spring or power means swings the blocker leg to abut its outer end against the stop lever so that when the load encounters the stop arm, the inertia and momentum forces of stopping the load is borne by the blocker leg and not borne by the spring or power means. This enables the use of a relatively weak spring and power means as the spring and power means are not required to stop and hold the load.
