In oted to the link 6 and at the other end to a this portion of the track is asharp depression extending from c to b, the track thence extending on a lower level for at least a short distance until the clutch is actuated. At or near the lower end I) of this inclined portion is located a cam 18, consisting, preferably, of a wedge-shaped piece located longitudinally between the rails and either formed of iron or faced with a steel or iron strip along its top. This incline or cam is arranged to contact with the depending hook 11 of the toggle and forces the toggle up into gripping position as the car moves'along the depressed portion of the track. The lower or front portion of the cam may be rounded or twisted to fit the hook 11 in its lower position, if desired, so that the cam-surface will fit the-lower face of the hook at all points in its length.

The cam is preferably pivoted at its lower end, its higher end being supported on a strong' spiral spring, as shown, to allow for wearing of the wheels or for slightly-different sizes of the wheels.

By depressing the track at the point where the clutch is engaged I am enabled to bring the clutch down over the rope and into proper position to engage it before the clutch is actuated. To move the car to this portion of the track, beginning at e the track may be provided with a slight grade, so that the car will travel by gravity, or the ear may be moved by any other suitable means. After the clutch has been automatically engaged the track may of course extend on any desired level, and as the car moves along it will lift the rope from its rollers or supports, the clutch traveling over them.

In Figs. 4 and 5 I show the arrangement for automatically disengaging the car from the haulage-rope. This disengaging means consists simply of an inverted cam device, which I show as consisting of an inclined angle 19, the inclination of Iwhich is forward and downward in the direction of the travel of the car. This disengaging device is preferably pivoted at its lower end, and its other end may be raised and lowered by a cam 20, actuated by a cam-lever 21. This lever serves to throw the device into operative or inoperative position, so that the car may be disengaged at this point or may remain clutched to the haulagerope. The device 19 is arranged so that it will engage the depending hook 11 and draw downwardly upon it as the car moves forward, thus opening the toggle and disengaging the rope, which will drop down below the toggle onto its supports. The shape of the face 18 of the grip-block through the downward strain of the rope enables the rope to assist in opening the clutch after the toggle has been moved slightly. A

The advantages of my invention result from lowering of the car so that the clutch will be brought in the proper position to engage the rope. This avoids any lifting of the rope into position for engagement and enables the clutch to be normally above the rope-level, so that there will be no accidental engagement. The clutch dev-ice is simple and easily operated and gives an eiiicient clutching action. The spring thereon compensates for any inequalities in the rope and also enables the final locking movement of the toggle to take place. The grip is automatically actuated and also automatically unlocked, if desired.

Many variations may be made in the form and arrangement of the grip or clutch, the car, or device for locking and unlocking the clutch, Sac., without departing from my invention.

I claim# 1. In a haulage system, a track having a depressed portion and a car having a gripping device arranged to be brought into alinement with the rope as the car moves down the incline; substantially as described.

2. In a haulage system, a track having a downward incline, a cam device at or adjacent to the incline and a car having a gripping device arranged to be brought into alinement with the rope as the car moves down the ineline; substantially as described. 3. The combination with a drivingrope,.of a car havinga gripping device, comprising jaws and means for locking the jaws upon the rope, said jaws being yieldingly clamped to compensate for inequalities in the rope; substantially as described.

4. The combination with a driving-rope of a car having clamping-jaws, and means for locking said jaws upon the rope, at least one of the jaws having a spring-backing to cornpensate for irregularities in the rope; substantially as described.

5. In a haulage system a car having a toggle device, a jaw actuated by the toggle device, a spring-backed jaw coacting with the togglejaw, and means for forcing the toggle above its straight-line position to lock the grip; substantiallyy as described.

6. A car having a gripping device comprising a toggle, a jaw actuated by the toggle, a p

depending hook on the toggle, and, a disengaging device arranged to engage the hook and unlock the toggle; substantially as described.

7. In ahaulage system, a driving-rope, acar having a gripping device, and means for raising and lowering the car relative to the rope to bring the gripping device into or out of alinement with said rope; substantially as described.

8. In a haulage system, a car having a gripping device, a cam device in the track arranged to automatically unlock the grip and connections for throwing the cam device into or out of operative position; substantially as described.

In testimony whereof I have hereunto set my hand.
