. SPECIFICATION forming part of Letters Patent No. 600,798, dated March 15, 1898.

Application filed November 10,1897. Serial No. 658,054. (No model.)

T0 @ZZ whom .it ntcty concern:

Be it known that I, CHARLES PIEZ, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Car-Hauls, of which the following is a specification.

The object of my invention is to so construct a car-haul for inclined planes that the breaking of the parts of the mechanism by the cars will be prevented, as fully described hereinafter.

I-Ieretofore car-haulshave been constructed with independent elevating and return tracks, each track having a drive-chain with lugs which engage the cars, so that a car will be elevated by one Vdrive-chain and will be returned down the inclined plane by another drive-chain, so that the car will not run away, but will always be Linder the control of the chains. In shifting the car from one track to another after the load has been discharged the cars have been allowed to run by gravity until stopped by one of the projections on the chain on the downhaul, and in many instances these cars come with such force against these lugs as to break them or injure the car; and the object of my invention is to provide mechanism by which the cars Will be carried to the downhaul-chain, and thus prevent the breakage of the parts.

In the accompanying drawings, Figure l isv a plan view of the upper portion of my improved car-haul, and Fig. 2 is a side view of Fig. 1.

In the drawings I have dispensed with the details of construction, such as the supporting structure and cross-ties, as theyl form no part of the present invention and only tend to confuse the drawings'.

A is the uptrack of the car-haul, and B is the downtrack, and connected to this downtrack is a track D, having a slight upgrade to the point where it joins the downtrack. This track D is connected to the uptrack A by the ordinary turnout-section E.

a is the drive-chain, of any suitable construction, in the present instance formed of a series of links coupled together by pins, and this drive-chain passes over wheels at each end, one at the top of the haul and one at the base, and the top Wheel a. is in the present instance the `driving-wheel. chain is a series of lugs a2, which project a certain distance, soas to engage with the axle t' of a car I, so that when the car is run onto the uptrack it will be engaged by one of the lugs and will be carried up the track to the section A', which has a slight downgrade to the point of discharge.

Z) is the drive-chain of the downhaul and is adapted to pass around wheels ina similar manner to the chain o., and in the present instance the wheel b is mounted on the driving-shaft b3, driven in any suitable manner, and on the chain are lugs b2, preferably of the same type as the lugs on the chain d, so that when the car passes onto the downhaul the axles will come in contact with the lugs and the car will be prevented from moving faster than the chain.

The switching-track E is in the present instance on a slight downgrade, so as to allow thecar to travel from the uptrack A to the sectional track D.

d is a drive-chain adapted to suitable carrying-wheels, the carrying-wheel d' being mounted on the driving-shaft b3, so that the chains b and d will be driven at the same speed. On the chain CZ are pivoted lugs d2, so pivoted that they can move freely forward in the direction of the arrow 1, Fig. 2. Should a car have momentum enough on traveling down the inclined track E to strike one of the lugs it would simply tilt it and pass the lug; but its momentum would be checked by the slight upgrade of the track D, so that the lug on the chain, which is driven at a uniform speed, will in time move faster-than the car and will come in contact with the axle and then will carry it forward to the point where the track D joins the downtrack B, and I preferably'make this junction slightly in advance of the point where it would be stopped by the lugs, so as to give the car sufficient momentum to free itself of the one lu g before being stopped by the other; but this momentum is not sufficient to in anyway injure the lug or the car. It will thus be seen that I am enabled to carry a car up the haul to the point of discharge and shift it over to the downhaul Without injury to either the mechanism or the car.

On this drive- Y IOO It will be understood that the drive-chain d may be mounted above the car instead of between the tracks, so as to engage a carbody, Without departing from my invention; but I prefer the construction shown as being more compact and out of the Way.

I claim as my inventionl. The combination with an inclined plane, of` a downhaul-track, a drive-chain having lugs adapted to engage with a car on the track, means for drivingthe chain at a given speed, whereby the lugs may engage with the car and prevent it from moving faster than the chain, a track-section communicating with the inclined plane and a drive-chain on said tracksection having lugs adapted to engage with the car on the track so that the car will be moved forward by the drive-chain to a point Where the track communicates with the downhaul, substantially as described.

2. The combination of the uphaul, a drivechain therefor, the doWnhaul, a carrier-chain therefor, provided with means for engaging a car to prevent its moving faster than the chain, with a track-section in advance of the downhaul, a drive-chain on said track-section adapted to engage with the car and to carry it over this track-section and to place it onto the tracks of the downhaul, substantially as described.

3. The combination of the uphaul, the drivechain therefor, having lugs adapted to engage a car and carry it up on the tracks, a downhaul, a drive-chain therefor also having lugs with which the car engages, a track-section inclined upward toward the point where it connects with the downhaul, a chain having lugs thereon adapted to engage the car and traverse it over the section to the downhaul, substantially as described.

4. The combination of the uptrack A, the downtrack B, the intervening section D having an upgrade to a point where it joins the downtrack B, a track E having a downgrade to a point where it joins the track D so that a car will be shifted from the uptrack to the track D by gravity, a drive-chain at the track D adapted to'convey the cars along the track D to the downtrack B, a drive-chain h With which the cars engage on the downtrack so that the cars will be carried down at a given speed, substantially as described.

5. The combination of the downgrade-track, a drive-chain, lugs thereon adapted to engage the car, an upgrade-track connected to the downgrade-track, a drive-chain adapted to convey the cars to the downgrade-track, said chain having pivoted engaging lugs so that the car as it is transferred onto this track, if traveling at a greater speed than the chain, will tilt the lugs, substantially as described.

In testimony whereof I have signed my name to this specification in the presence ot two subscribing Witnesses.
