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 an important feature of the invention, an improved anchor plate arrangement is provided for connecting one end of the outer sheath member with one end of the stationary mounting plate assembly.

Brake cable operating apparatus including anchor plate spacer

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. In order to effect reserve travel of the operating lever beyond the normal brake fully applied position, the bow-shaped connecting link may include a plurality of pivotally connected sections that are foldable about the pivot axis of the operating lever, thereby to permit additional tensioning of the inner brake cable under emergency hand braking conditions.

Brake cable operating means of the overcenter toggle type

A brake cable operating lever is disclosed including a device for adjusting the cable tension which is produced when the operating lever is in the brake-on position, characterized in that the rotary tension adjusting screw (36) which extends axially of the operating lever includes intermediate its ends an annular collar portion (36a) that is rotatably supported by an abutment shoulder (20f) on the operating lever (20), whereby the apparatus remains operable even if the manual operating knob (38) were to be removed from the screw member. An internal friction producing device (40) is provided for restricting rotation of the screw member about its axis.

Cable tension adjusting means for a brake cable operating lever

A parking brake operating mechanism is disclosed which includes a ratchet link and an operating lever pivotally connected with a bracket housing so as to effect a mechanical advantage when displacing the brake cable operating pin in the brake-engaged direction. The ratchet link is pivotally connected intermediate its ends with the housing by a first pivot axis, and the operating lever is pivotally connected intermediate its ends with one end of the ratchet link by a second pivot axis, one end of the operating lever being connected with the pin that operates the parking brake cable. The first and second pivot axes are arranged generally on opposite sides of the brake cable pin, the distance between said axes being greater than the distance between the pin axis and the first axis, thereby to effect the desired mechanical advantage. A pawl cooperates with ratchet teeth on the ratchet link to normally prevent pivotal movement thereof in the brake-released direction.

Brake cable operating means affording a mechanical advantage

A locking assembly for locking the tilt cab of a vehicle to the vehicle chassis frame is disclosed, including a locking pin slidably connected with a housing for displacement between locked and unlocked positions relative to the locking opening of a blade member that extends within a corresponding cavity contained within the housing when the tilt cab is in its lowered condition, characterized by the provision of an interlocking device that automatically prevents displacement of the locking pin to the locked position when the blade member is not completely seated in the cavity.

Tilt-cab locking device including interlock means

An improved locking device of the hook and transverse pin type is disclosed for locking together a pair of components, characterized by the provision of a cam member that is displaceable by linearly operable cam operating means to operate a hook member between locked, safety and fully released positions relative to a locking pin member. In one embodiment, the cam member is linearly displaceable throughout its entire length of travel between locking, safety and releasing positions by the cam operating means, and in a second embodiment, the cam member is pivotally displaceable between the locking and safety positions, and linearly displaceable between the safety and releasing positions. A pawl device may be provided for normally locking the cam member in its releasing position when the pin and hook housings are separated, said pawl device being operable to its unlocked condition when the pin and hook housings are returned to their adjacent contiguous position.

Locking hook and pin apparatus for locking together a pair of components

Improved heavy duty locking means are disclosed for locking together a pair of movable components such as the tilt cab and chassis components of a motor vehicle, characterized by the provision of movable locking pin means for releasably connecting the blade and housing members secured to adjacent surfaces of the components, respectively. In one embodiment, the locking pin is connected with the housing member for axial displacement between locked and released positions relative to a locking aperture contained in one end of the blade member. In another embodiment, the locking pin is connected for lateral displacement relative to a locking slot contained in a lateral surface of the blade member. The locking pin may be actuated by piston and cylinder motor means or by a manually-operable linearly-displaceable actuator. In various embodiments of the apparatus, the motor means and the locking pin are arranged on the same and on opposite sides of the blade and housing members, respectively. In each of the embodiments, the locking pin is spring-biased toward the locked position relative to the locking opening contained in the blade member.
