Abstract
A railway-car impact-testing method and apparatus whereby the active railway-car is caused to move down an incline and impact against a passive railway-car, the momentum of which is braked by a force storing means which then transfers stored force to the latter car to displace the cars in the opposite direction. A drive rope flanking the rails is used to displace the cars to their respective positions or to brake the displacement of the cars.
Claims13
A method of impact-testing a railway car comprising the steps of:
- entraining a first railway car along a stretch of track from an initial position with a drive rope displaced alongside said track;
- intercepting the first railway car with a second railway car under impact, thereby causing said second railway car to rebound along said track in the direction of displacement of the first railway car;
- braking the momentum of said second railway car while storing force upon the braking of the momentum of said second railway car;
- and
- displacing said second railway car in the opposite direction along said track at least in part with the stored force.
2 more elements
An apparatus for the impact-testing of railway cars comprising:
- a length of track;
- force-storing means at one end of said length of track for braking the momentum of a railway car and producing a stored force thereby;
- a drive rope extending along said track for displacing an active railway car therealong;
- a capstan operatively connected to said rope for displacing same;
- a plurality of columns flanking said track and provided with guide rollers over which said rope is passed;
- energy-absorbing means in said columns for yieldably supporting said pulleys;
- means for hooking an active railway car to said rope for entrainment thereby;
- and
- another railway car positioned on said track and engageable under impact by said active railway car to rebound along said track and cooperate with said force-storing means, said force storing means displacing said another railway car in the direction opposite its rebound direction with said stored force.
