Title: Roller bank sensor contact system
Claims: The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 1. In a sensor having a housing provided with a pair of spaced linear bearing portions, a pair of flexible bands of spring material disposed between the bearing portions and being forced thereby into generally elongate shape, the adjacent portions of the bands being secured to each other and the remote portions of the bands engaging and being secured to a respective bearing portion, a velocity change of predetermined extent causing the bands to concurrently roll relative to each other along the bearing portions and linearly translate the adjacent secured portions of the bands relative to the bearing portions, the improvement comprising, a pair of first elongated resilient contact members intermediately secured to the bands and having free end portions extending oppositely therefrom and a pair of flexibly related angular second contact members mounted on the housing in spaced relationship to the first contact members and interengageable therewith, the first contact members laterally separating and the second contact members laterally and flexibly contracting about their apical juncture upon interengagement to thereby substantially eliminate contact bounce. 2. In a sensor having a housing provided with a pair of spaced linear bearing portions, a pair of flexible bands of spring material disposed between the bearing portions and being forced thereby into generally elongate shape, the adjacent portions of the bands being secured to each other and the remote portions of the bands engaging and being secured to a respective bearing portion, a velocity change of predetermined extent causing the bands to concurrently roll relative to each other along the bearing portions and linearly translate the adjacent secured portions of the bands relative to the bearing portions, the improvement comprising, first contact means extending from the adjacent secured portions of the bands for translation therewith, and second contact means mounted on the housing in spaced relationship to the first contact means and interengageable therewith upon translation thereof, one contact means being laterally separable and the other contact means being laterally contractable about an apical juncture thereof upon interengagement of the contact means to substantially eliminate contact bounce. 3. In a sensor having a housing provided with a pair of spaced linear bearing portions, a pair of flexible bands of spring material disposed between the bearing portions and being forced thereby into generally elongate shape, the adjacent portions of the bands being secured to each other and the remote portions of the bands engaging and being secured to a respective bearing portion, a velocity change of predetermined extent causing the bands to concurrently roll relative to each other along the bearing portions and linearly translate the adjacent secured portions of the bands relative to the bearing portions, the improvement comprising, first contact means extending from the adjacent secured portions of the bands for translation therewith and including a pair of resiliently separable contact members, and second contact means mounted on the housing in spaced relationship to the first contact means and including a pair of contact members laterally contractable about an apical juncture, the second contact members being interengageable with the first contact members upon translation thereof to resiliently separate said first contact members while concurrently laterally contracting to thereby substantially eliminate contact bounce. 4. In a sensor having a housing provided with a pair of spaced linear bearing portions, a pair of flexible bands of spring material disposed between the bearing portions and being forced thereby into generally elongate shape, the adjacent portions of the bands being secured to each other and the remote portions of the bands engaging and being secured to a respective bearing portion, a velocity change of predetermined extend causing the bands to concurrently roll relative to each other along the bearing portions and linearly translate the adjacent secured portions of the bands relative to the bearing portions, the improvement comprising, first contact means including a pair of elongated resilient contact members secured at one end thereof to the adjacent secured portions of the bands for translation therewith and having their other free ends resiliently separable, and a generally V shaped second contact member having the apically joined legs thereof mounted on the housing and located in spaced relationship to the free ends of the first contact members, translation of the first contact members into engagement with the legs of the second contact member resiliently separating the free ends of the first contact members and concurrently contracting the legs of the second contact member to substantially eliminate contact bounce. 5. In a sensor having a housing provided with a pair of spaced linear bearing portions, a pair of flexible bands of spring material disposed between the bearing portions and being forced thereby into generally elongate shape, the adjacent portions of the bands being secured to each other and the remote portions of the bands engaging and being secured to a respective bearing portion, a velocity change of predetermined extent causing the bands to concurrently roll relative to each other along the bearing portions and linearly translate the adjacent secured portions of the bands relative to the bearing portions, the improvement comprising, first elongated contact means having free end portions extending oppositely from the adjacent secured portions of the bands, means on the housing engaging one free end portion to locate the bands in unactuated position, and second contact means mounted on the housing in spaced relationship to the other free end portion of the first contact means and having a free end portion interengageable therewith upon translation thereof to substantially eliminate contact bounce, one free end portion of one contact means including laterally separable contact members and the free end portion of the other contact means including apically joined laterally contractable contact members.
