SPECIFICATION forming part of Letters Patent No. 707,200, dated August 19, 1902.

Application filed September 20, 190 l--" Serial No. 75,917. (No model.) I

To all whom it may concern: I

Be it known that I, SIDNEY W. BOLLINGER, a citizen of the United States,residin g at Pittsburg, in the county ofAllegheny and State of Pennsylvania, haveinvented or discovered new and useful Improvements in Car-Hauls, of which the following is aspecification.

In the acc'ompanying'drawings, which make part of this specificationfFigure I is a side elevation of the'down-haul chain, showing the 1g. II is a detail perspective oflinks and hooks. Fig. III is a cross-section on line III III of Fig. I, showing a hook raised andits bottom in contact with the supporting-plate; f Fig. IV is a cross-section on line IV IV of Fig.1, showin g a hook lowered and its lower end'between the guides.

The object of my invention, generally stated, is to provide means for the automatic handling of mine-cars on the down-haul chain of a car-haul.

section of the chain to the downgrade and also for controlling cars while on the downgrade.

In the accompanying drawings,1 represents. an endless chain. 2 is an idler-wheel, and 3 3 are sprocket-wheels located at each end of the loop. Only one is shown in the drawings.

The chain 1 consists of links arranged in pairs and at suitable points,having pivoted 1 hooks 4: and 5, arranged so as to engage the.

car 6 in opposite directions.

Hook I is pivotally connected to the links 7 7 and is provided with an overbalanced end 8. V

. Hook 5 is pivotally secured to links 11 11 by means of pin 12.

13 is aslot in the forward end of hook 5. in 14, secured to the linklll 11, passes through slot 13 and acts as a stop in the swinging movement of said hook. Preferably these thelinks without departing from my invention.

15 represents a support for chain 1.

-; 16 is a slot formed between the downwardlyextending flanges of support 15.

17 is a channel-shaped guide for the chain 1 on the downgrade portion of the chain.

In'the operation of my invention a car after being unloaded'and returned in the usual manner over the customary cross-over switch and extension-track runs by gravity down and over'sprockefiwheelfi and along the rails (not shown) ateach side of chain 1. The inclination of the track at position 9 causes the car to-slow -down andstop. As the car 6is moving forward over the chain 1 to its stopping position bar 10, which. is secured .to the car, will knock down andpass over hook 4, after which :thehook immediately assumes its proper position.

. In the chains forward travel the hook 4. engages the bar 10 of car 6 and moves the car forward and over the idler wheel 2. Hook 5 afterzopassing over sprocket-wheel 3 drops to its lowest position, which permits the bar 10 to pass over. The lower portion of'the hook enters the slot 16 and travels along said slot untilidler-whe'el 2 is reached, when it raises up out of the slot and assumes its highest p0- sition,remaining up and next enters the channel 17. The bottom of the channel holds the hook up in position to engage bar 10. After hooket has pushedcarti over the idler-wheel 2 the car pitches forward slightly and the bar '10 comes into contact'with hook 5, holding v ;the car in check and traveling down the grade {at whatever speedthe chain travels.

Having describedmyginvention, I claim- 1. In acar-haul, achain, hooks pivotally secured thereto and arranged so that alternate hooks engage a stop on a car in opposite directions. 1

'2. In a car-haul, abhain-support, a slot in said support, a chain, a hook pivotally secured to said chain anda second chain-support, said chain-supportsiand said slot providing means for lowe'ringiand raising the end of said hook.

3. In a car-haul chain, a hook pivotally secured at one end to the link of said chain, a Signed at Pittsburg this 18th day of Sepslot in said hook and a pin through said slot tember, 1901. and secured to said link.

4. In a car-haul, a cai'havinga, stop, a chain, 5 a hook pivotally secured thereto and means Vitnesses:
