Abstract: A device associated with a load cell for protecting against overload conditions, which includes a first bracket assembly connected to the load application portion of the load cell and a second bracket assembly slidably mounted on the first bracket assembly and connected thereto through elements that normally prohibit slidable movement between the bracket assemblies but permit slidable movement therebetween in a given overload situation.

Abstract: A method for assembling a wiper blade with a wiper arm wherein the wiper blade consists of a backing strip having keyhole-shaped slots therein and an open aperture at one end of the strip, along with a multifarious wiping element having a plurality of T-shaped projections for fitting in the keyhole-shaped slots in the backing strip and a projection at the end thereof for buttoning the backing strip to the wiping element upon stretching the wiping element. The steps of the method define the sequence of steps of aligning the projections with the slots and stretching the wiping element to align the projection with the open aperture whereupon release of the stretched wiping element completes the assembly.

Abstract: A headlamp wiper assembly, for spraying and wiping headlamps including one or more wiper arms and blades fixed to pivot about a common axis with the wiper blade consisting of a backing strip having key slots therein and an open aperture at one end, along with a multifarious wiping element having a plurality of T-shaped projections for fitting in the key slots in the backing strip and a projection at the end thereof for buttoning the backing strip to the wiping element upon stretching the wiping element. The wiping element is provided with a plurality of angularly related wiper facets for engaging with and cleaning the headlamp. The assembly is provided with a drive shaft interconnected to oscillate the wiper arm and blade through a bracket assembly, the end portion of the drive shaft being provided with a nozzle means having one or more openings and oscillates with the wiper arms and blades and sprays the headlamps adjacent the wiping element as they oscillate.
