CAR-HAUL.

To allwhom it may concern.:

Specification of Letters Patent.

Application led February 24, 1909.

va citizen of the United States, anda .resident of Cleveland, county Vof Cuyahoga, `and State of Ohio, have invented a newand useful Improvement in Car-Hauls, of which the folflowing is a specification, the principle of the `invention being herein explained and the best inode `in which I have contemplated apl plying that principle, so as to distinguish it' from other inventions.

The present invention relating as indicated to car-hauls, has more particular regard to the provision of means for retarding the speed of cars when shunted on the main .track of the haul from the shifting track,

whereby such cars may -be delivered without shock to the hooks ofthe haul chain.

The object .of the invention Ais the provision `of simple and eective means for accoinplishing this result, which means shall;

furthermore be entirely automatic in their1 operation.

To the accomplishment of .this and Vrelated 2 ends, said invention then consists of theE Ameans hereinafter fully `described and par-.

ticularly pointed out in claims.

The annexed drawing and the following Vdescription set forth in detail certain mech-l anisms embodying the invention, such dis-2 closed inea-iis constituting, however, but one@ of various mechanical forms in which the principle of the invention may -be used.

In said annexed drawing Figure 1 is a` diagrammatic side view of a car haul illus-` tiating one inode of installing my improved construction referred to above; Fig. 2 is a side elevation on a considerably larger scale,

of a detail of the haul chain, showing thej parts thereof in one operative position; while Figs. 3 and 4 are similar Views of said detail, showing the parts in other operativey positions.

My improved car-haul construction, inf volves the use of a hump, or raised portion,

in the track, which hump is designed to be of suficient elevation, to overcome the iinpetus of the car that is shunted on to the said 2 track. This feature Aof a hump is not pre-y sented as being broadly new, the present invention being directed to the provision of means for properly placing cars with respect to the car haul chain; as such cars are discharged oiito the main haul track for, as will be obvious, unless the elevation of the hump vquestion.

ythereover, `it will run up as far as its initial impetus will carry it, and then move backwardly, in which event it will be apt to encounter -the succeeding car with .prospect of damage and interruption of operation.

Referring first of all to Fig. l, showing as lhas been stated, but one typical illustrai tion of -iny improvement, A 'represents the track of a lowering, or down haul along which passes in the direction indicated by the arrow, the down haul chain B. The latter is provided at suitable intervals with hooks or dogs b in the present instance to engage with the forward axles of cars on said track to retard their movement, as will be readily understood. The track or stai tion from which the cars are fed on to the main dowii haul, is not shown, but the portion of such haul immediately adjacent to such station, is inclined upwardly, as is shown, so as to form a hump a of the character 'hereinbefore referred to. From such hump the track A accordingly inclines downwardly in A'both directions. The portion of the down haul chain, B corresponding with inclined track-section A is depressed for the major portion of such sections length so as to bring the dogs b below the level where they are effective to engage the car,y and is not until approximately the summit of the hump is reached that the chain is elevated to the proper position for engaging cars. A car discharged onto the track, it will accordingly be seen, is free to move along the same to such summit, before it will be engaged by the hooks in Associated with each of these ldogs '2), whereby forward movement of the car, when the chain is properly positioned, is prevented .other than in unison with the chain, isa second oppositely disposed dog rising to substantially the same height and provided with a pivoted member b2 that in the normal upright position in which its own weight maintains it, rises a sufficient llO distance above the height just indicated, to engage a car axle even along that portion of the track, where the chain is depressed in the manner previously described. Such pivoted member moreover is free to move in a forward direction e. toward the other dog of the particular pair in question) only, being located against movement in the opposite direction. By reason of this construction of the pivotal dog portion Z22, it does not interfere with the forward movement of a car up onto the hump but will prevent such cars return, so that it will be retained at whatever point it may have reached in ascending the hump and be carried on over, by virtue of such engagement. As the summit is reached, both of the dogs, as has been stated, rise to full operative position, and the axle is now held, not merely against backward movement by the auxiliary dog b, but is safely positioned behind the forward dog b that prevents it racing down the car haul proper. The successive relative positions of the two dogs and the axle c, of a car C, will be clearly understood by reference to Figs. 2, 3 and i, in the first of which the axle is shown as passing over the rear or auxiliary dog, the pivotal member b2 of the latter appearing in depressed position; the second view represents such axle after passing over dog in question; and the third represents the axle safely pocketed between the two dogs and in contact with former, which is the position occupied pending descent of the down haul.

From the foregoing' description of the construction and operation of my improved car haul, it will be obvious that its action is entirely automatic and positive. At the same time its simplicity, compared with the auxiliary hauls and like contrvances that have heretofore been employed in this connection, will commend it. By way of conclusion it should be remarked that the construction of dog shown, may by simple reversal in position be adapted equally well for the feeding of cars onto a haul arranged to convey such cars from a lower to a higher level. No modification of construction being required, it is not deemed necessary to illustrate the arrangement of apparatus for this purpose. Moreover, my improved construction of haul is not limited necessarily to use with a track having a hump or one, in other words, that inclines oppositely in different portions; but one such portion may be disposed horizontally, that is on the level without introducing any variation in the principle of operation involved. This remark applies more particularly to the upper section A of the haul as illustrated. Note should finally be made that the word cable as herein employed is designed to connote not only a cable (2'. e. a rope) in the stricter sense of the term but also generically either a chain or any equivalent extended hauling or pulling means.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention l. In a car-haul, the combination with a track inclining downwardly in both directions from an intermediate point; of a cable passing along said track and provided with a plurality of spaced pairs of oppositely disposed dogs, corresponding dogs of such pairs being adapted to engage a car to prevent movement thereof down one such inclined track portion, and the other dogs projecting' higher and being pivoted to swing freely toward such first-named dogs but locked against such movement in the opposite direction, whereby a car may pass over such pivotal dog but not back again, said cable being sufficiently elevated along such rst track portion to render both dogs operative but being depressed along the other track portion so as to leave only said pivotal dogs operative. i

2. 1n a car-haul, the combination with a track inclining downwardly in both directions from an intermediate point; ofa cable passing along' said track; and a plurality of spaced pairs of oppositely disposed dogs borne by said cable, corresponding dogs of such pairs being adapted to engage a car to prevent movement thereof down one such inclined track portion but said cable being` depressed along such other track portion so as to render said dogs inoperative, the other dogs having' upwardly projecting portions that are thus operative and pivoted to swing freely toward such first-named dogs but locked against movement in the opposite direction, whereby a car may pass over such pivotal dogs but not back again, said cable assuming its normal elevation as it passes over the hump between said track portions whereby the other dogs are rendered operative and such car thus held against movement down the other track portion.

Signed by me this 20th day of February, 1909.
