Vehicle acceleration and deceleration indicator

Claim 1

A device connectable to a vehicle engine manifold for indicating acceleration and deceleration of the vehicle comprising: a Bourdon tube connectable to said manifold having a free end movable proportionally to pressure developed within said manifold; a first switch having a first contact and a second contact and a first spring member extending therebetween, said member being engaged with and movable by said free end and having a third contact opposite said first contact and a fourth contact opposite said second contact, said first and third contacts and said second and fourth contacts being opened and closed by movement of said member; second switch means operably connected to said first switch; third switch meaNs operably connected to said first switch; an acceleration light connected to and operable by said second switch means; and, a deceleration light connected to and operable by said third switch means; and wherein: said first and third contacts are open when said vehicle is accelerating, said second and fourth contacts are closed only when said vehicle is accelerating; said third and fourth contacts are connected via said member to a source of electrical energy; said second switch means is operably connected to said second contact; and, said third switch means is operably connected to said first contact; and wherein: said first switch has a second spring member with said first contact mounted thereon and additionally comprising: adjustment means operable to move said second spring member to change the spacing between said first and third contacts.

Claim 2

A device connectable to a vehicle engine manifold for indicating acceleration and deceleration of the vehicle comprising: a Bourdon tube connectable to said manifold having a free end movable proportionally to pressure developed within said manifold; a first switch having a first contact and a second contact and a first spring member extending therebetween, said member being engaged with and movable by said free end and having a third contact opposite said first contact and a fourth contact opposite said second contact, said first and third contacts and said second and fourth contacts being opened and closed by movement of said member; second switch means operably connected to said first switch; third switch meaNs operably connected to said first switch; an acceleration light connected to and operable by said second switch means; and, a deceleration light connected to and operable by said third switch means; and wherein: said first and third contacts are open when said vehicle is accelerating, said second and fourth contacts are closed only when said vehicle is accelerating; said third and fourth contacts are connected via said member to a source of electrical energy; said second switch means is operably connected to said second contact; and, said third switch means is operably connected to said first contact; and wherein: said first switch has a second spring member with said first contact mounted thereon and additionally comprising: adjustment means operable to move said second spring member to change the spacing between said first and third contacts.
