Claim:
A push block comprising: an arm having a length defined by a first end and a second end wherein the second end in a position opposite to the first end; a tire beam having a length defined by a first end beam and a second end wherein the second end is in a position opposite to the first end of the tire beam; a bumper connected to the arm and the tire beam wherein the bumper has an inner surface and an outer surface wherein the outer surface is in a position opposite to the inner surface; a first pivot on the arm wherein the first pivot on the arm connects the bumper to the second end of the arm; a second pivot on the arm wherein the second pivot on the arm is positioned at the first end of the arm; a first pivot on the tire beam wherein the first pivot on the tire beam connects the bumper to the second end of the tire beam wherein the first pivot on the tire beam is positioned at a distance from the first pivot on the arm; a second pivot on the tire beam wherein the second pivot on the tire beam is positioned at the first end of the tire beam wherein the second pivot on the tire beam is positioned at a distance from the second pivot on the arm wherein the distance of the second pivot on the tire beam from the second pivot on the arm is equal to the distance of the first pivot on the tire beam from the first pivot on the arm wherein the second pivot on the tire beam is a distance from the first pivot on the tire beam wherein the distance of the second pivot on the tire beam from the first pivot on the tire beam is equal to the length of the arm.
