  • Patent number: 7134220
    Abstract: A fluid level measuring device, also referred to as a dipstick, for measuring the fluid level in a fluid reservoir or tank, such as an oil pan or transmission reservoir in an internal combustion engine. The fluid level measuring device includes a stationary tube onto which lugs can be directly attached. The dipstick assembly includes a fluid level indicator measuring blade attached to an elongated shaft that is molded into a plastic handle assembly. The plastic handle assembly includes a bayonet type locking mechanism for locking the handle to the stationary tube assembly. A compressible seal forms a pressurized seal between the stationary tube assembly and the handle.

  • Patent number: 4872368
    Abstract: A cable operating apparatus includes a pawl and ratchet arrangement for maintaining an operating lever in a cable-tensioning position. The pawl is bifurcated to define a pair of pawl tips, the pawl being pivotable in opposite directions for effecting alternate engagement of the pawl tips with the ratchet. The pawl contains a slot that receives the pawl pivot pin and which permits lateral movement of the pawl between a pair of end positions. An overcenter spring arrangement alternately pivotally biases the pawl in opposite directions when the pawl is displaced toward the end positions, respectively. A cam arrangement serves to effect lateral displacement and pivotal movement of the pawl when the operating lever is pivoted from the released position toward a cable tensioning position.

  • Patent number: 4850242
    Abstract: A soft-release lever-operated control system for parking brake cables is disclosed including a helical main clutch spring arrangement permitting movement of the operating lever only toward the brake-engaged position, and a release device for releasing the main clutch spring to permit return of the operating lever toward the brake-released position. According to another embodiment of the invention, a second helical clutch spring arrangement is provided that is activated when the operating cable is returned to the brake-released position, thereby to activate a cable tension adjusting device that removes slack contained in the inner brake cable operating member. According to a further embodiment, a push-to-release arrangement including a toggle pawl and spring device is operable upon tapping of the operating lever to place the system in a brake-released condition.

  • Patent number: 4841798
    Abstract: An improved parking brake cable control apparatus includes an automatic cable tensioning device that is operable at the beginning and end of every parking brake operating cycle to take up cable slack and maintain uniform cable tension. The foot-operated parking brake lever pivots on a main pivot shaft between brake-engaged and brake-released positions, a releasable pedal pawl being provided that cooperates with a conventional pedal ratchet. A cable-tensioning ratchet connected with the parking brake cable is rotatably mounted on the main pivot shaft, and cooperating therewith are a lock pawl and a drive pawl connected with the apparatus housing and with the lever, respectively. The lock pawl is released by a release lever when the pedal is pivoted toward the released position, and the drive pawl is disengaged when the lever is adjacent the disengaged position, thereby to activate the cable tensioning device.
