Abstract
Abstract This invention pertains to an energy absorber for use on abutments or on the front of vehicles to absorb energy when the vehicle abuts against another vehicle or a vehicle abuts against an abutment such as a divider between two roads, highways or freeways, a bridge support, a guard rail end, a bridge rail end, a sign support, a pole, etc.; the absorber to be composed of one or more tires, new or used, and filled with a liquid such as water (with salt, etc., to prevent freezing in cold climates) and with one or more blow out plugs to allow the liquid to escape when impacted, the ends or rim sides of the tires being closed and connected by flexible or collapsible means.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
99 words
An energy absorber for a vehicle comprising, a pneumatic tire casing having an aperture through its peripheral wall portion, said casing having a circular rim opening in each side wall thereof, a separate and discrete closure means on each side of said casing and spaced from each other for closing said rim openings to enclose, liquid-tight, a volume of liquid substantially filling said casing, a blowout plug normally tightly seated in said aperture and ejectable by hydraulic pressure upon application of a predetermined force against said casing, and means for securing said casing to one end of a vehicle.
Claim 2
Dependent Claim
99 words
An energy absorber for a vehicle comprising, a pneumatic tire casing having an aperture through its peripheral wall portion, said casing having a circular rim opening in each side wall thereof, a separate and discrete closure means on each side of said casing and spaced from each other for closing said rim openings to enclose, liquid-tight, a volume of liquid substantially filling said casing, a blowout plug normally tightly seated in said aperture and ejectable by hydraulic pressure upon application of a predetermined force against said casing, and means for securing said casing to one end of a vehicle.
Claim 3
Dependent Claim
99 words
An energy absorber for a vehicle comprising, a pneumatic tire casing having an aperture through its peripheral wall portion, said casing having a circular rim opening in each side wall thereof, a separate and discrete closure means on each side of said casing and spaced from each other for closing said rim openings to enclose, liquid-tight, a volume of liquid substantially filling said casing, a blowout plug normally tightly seated in said aperture and ejectable by hydraulic pressure upon application of a predetermined force against said casing, and means for securing said casing to one end of a vehicle.
Claim 4
Dependent Claim
99 words
An energy absorber for a vehicle comprising, a pneumatic tire casing having an aperture through its peripheral wall portion, said casing having a circular rim opening in each side wall thereof, a separate and discrete closure means on each side of said casing and spaced from each other for closing said rim openings to enclose, liquid-tight, a volume of liquid substantially filling said casing, a blowout plug normally tightly seated in said aperture and ejectable by hydraulic pressure upon application of a predetermined force against said casing, and means for securing said casing to one end of a vehicle.
Claim 5
Dependent Claim
26 words
An energy absorber in accordance with claim 3 wherein said casing is secured with its sides substantially normal to the path of movement of the vehicle.
Claim 6
Dependent Claim

An energy absorber according to claim 2 wherein said blowout plug is located on the upper periphery of the casing.
Claim 7
Dependent Claim
36 words
An energy absorber in accordance with claim 3 wherein at least one of said closure means comprises a pair of discs secured together in opposed relation with the wall of one rim opening between the discs.
Claim 8
Dependent Claim
25 words
An energy absorber in accordance with claim 4 wherein said casing is secured to the vehicle with its sides substantially normal to the path thereof.
Claim 9
Dependent Claim
101 words
An energy absorber in accordance with claim 5 wherein at least one of said closure means comprises a second pneumatic tire casing secured in side-by-side relation to the first mentioned casing and having a rim opening in each of its side walls, said second casing having a closure means closing its outer rim opening to enclose liquid tight, a volume of liquid substantially filling said casing, said second casing having an aperture through its peripheral wall portion and a plug within the aperture ejectable by hydraulic pressure of the liquid upon application of a predetermined force against said second tire casing.
