Abstract: An improved brake lever assembly of the overcenter toggle type is disclosed, wherein the brake operating lever is preferably pivotally connected with the stationary mounting plate assembly about a pivot axis that is laterally displaced from the linear axis of travel of an inner cable member relative to the concentrically arranged tubular outer sheath, thereby to reduce wear of the inner cable guide means. According to a first feature of the invention, an improved anchor plate or anchor plate arrangement is provided for connecting one end of the outer sheath member with one end of the stationary mounting plate assembly. In accordance with a second feature, a ratchet and pawl assembly is provided for releasably locking the operating lever in various angular positions relative to the mounting plate assembly.

Abstract: A switch actuator of the time-delay type is disclosed for operating an electrical switch having an ON-OFF lever, including a mounting plate upon which is secured a cylinder closed at one end and open at the other end to the atmosphere. A piston is slidably disposed within the cylinder and includes a one-way seal member which defines at the closed end of the cylinder a substantially fluid-tight chamber. The piston, which is normally spring-biased toward the open end of the cylinder, is displaceable against the force of the spring toward a first position adjacent the closed end of the cylinder, thereby to force the fluid quickly out of the sealed chamber past the one-way seal. An operating member movably connected with the switch plate pivots the switch lever to the ON position when the piston is in the first position.

Abstract: Heavy duty locking apparatus is disclosed for locking together a pair of relatively movable members, such as the tilt cab and chassis components of a motor vehicle, wherein a movable locking pin is employed for releasably connecting the blade and housing elements which are respectively secured to said relatively movable members. In one form of the invention, the locking pin is laterally projected into the corresponding opening in the blade element but does not pass completely through the opening. Also, in the one form, the opening or cavity in the housing element is of substantial size in order to present an enlarged target area for entry of the blade element during the locking operation. A second form of the invention is similar to the first form in the above respects and includes a modification of the blade element and the housing part to improve the supporting relationship between these elements during the locking operation.
