Description: |
| "The modern streamlined automobile is difficult to raise, for the purpose of changing a tire, by known type jacks because the considerable extension of the body beyond the front and rear wheels makes it exremely difficult to locate a part fixed to the wheel in order to engage it by any known wheel or axle jack; the skirted fenders in many cars so overhand the wheels or tires that it is impossible to change a tire without raising the body with respect to the wheel; and the extreme flexibility or extensibility of the springs makes it necessary to raise the car body to such a height by known bumper jacks that the use of such bumper jacks is sometimes hazardous, particularly on a hillside, a crowned road, or on unlevel ground..." |
