Abstract
Abstract Vibration sensing and responding apparatus which includes a concave spherical surface and a ball disposed on said surface. Spring loaded means extends through said surface and is retained in position by said ball. Should the ball be displaced by horizontal vibration of the surface or be displaced by a mechanism responding to vertical vibration, the spring loaded means will move upwardly and in so doing actuate a device coupled thereto.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
187 words
A device for sensing vibration and responding thereto to actuate a utilization device, comprising a spherical ball, a ball saucer having a spherical inner surface for sustaining said ball, the radius of curvature of said inner surface being sufficiently greater than the radius of said ball, a depression formed in the bottom of said inner surface, a reciprocable member substantially disposed in said depression and placed just under said ball in the normal stationary condition, means of urging said reciprocable member upwardly such that said reciprocable member can not move against the weight of said ball in the normal stationary condition but can move upwardly to protrude from the inner surface of said ball saucer when said ball leaves said reciprocable member, and means for coupling said reciprocable member to said utilization device for actuating said utilization device in response to the vertical motion of said reciprocable member, said device further comprising a suspension weight suspended vertically by a spring to allow a vertical vibration, a kicking mechanism coupled to said suspension weight for displacing said ball in response to the vertical vibration of said suspension weight.
Claim 2
Independent Claim
187 words
A device for sensing vibration and responding thereto to actuate a utilization device, comprising a spherical ball, a ball saucer having a spherical inner surface for sustaining said ball, the radius of curvature of said inner surface being sufficiently greater than the radius of said ball, a depression formed in the bottom of said inner surface, a reciprocable member substantially disposed in said depression and placed just under said ball in the normal stationary condition, means of urging said reciprocable member upwardly such that said reciprocable member can not move against the weight of said ball in the normal stationary condition but can move upwardly to protrude from the inner surface of said ball saucer when said ball leaves said reciprocable member, and means for coupling said reciprocable member to said utilization device for actuating said utilization device in response to the vertical motion of said reciprocable member, said device further comprising a suspension weight suspended vertically by a spring to allow a vertical vibration, a kicking mechanism coupled to said suspension weight for displacing said ball in response to the vertical vibration of said suspension weight.
Claim 3
Dependent Claim
80 words
The device according to claim 1, characterized in that said suspension weight is located over said ball and said kicking mechanism comprises a vertical rod extending downwardly from said suspension weight, the lower end of said rod being positioned just above said ball and a little offset from the vertical axis of said ball in the normal stationary condition, whereby the vertical movement of said suspension weight results in displacement of said ball by said lower end of the rod.
