MECHANISM FOR HANIOLING C335.

Specification of Letters Patent.

Patented June so, 1908 Application filed March 16, 1908. Serial No. 421,375.

To all whom it may concern:

Be it known that I, GRANT HoLMEs, a citizen of the United States, residing at Danville, in the county of Vermilion and 'State of Illinois, have invented certain new and useful Im rovements in Mechanism for Handling s ecification, reference being bad therein to t e accompanying drawings.

This invention relates to mechanism for handling cars, and is designed more articularly for, handling mine cars in coa mines and similar places.

The object of the invention is to provide mechanism by means of which the mine cars will be handled to and from the hoisting cage Without the intervention of the operator, and, to this end, it is a further object of the invention to provide such a mechanism comprising a car lift which will be actuated by the downward movement of the cage; to

provide a cushioned landing platform for the cage; and to provide an automatically operated eager and sump guard.

With these objects in View my invention consists in certain noval features of. con struction and in certain arts and combinations hereinafter to be escribed, and then more plarticularly pointed out in the claims.

In t e accompanying drawin Figure lis a side elevation of a car hand ing mechan ism embodying my invention; Fig.2 is a top plan view of the same; Fig. 3 is an enlar ed view, partly in section, of the landing p atform and its operating mechanism, to-

sum guard; and Fig. 4 isan enlarged view of t e car-lifting mechanism.

In thesedrawings I have illustrated the preferred form of my invention and have shown the same as comprising a pluralit of refera ly 'two in num er, each of said trac s comprising a forward or delivery-portion 1, by means of which cars are fed or delivered to the hoistin cage, and a rear or discharge portion 2 whic is located at a somewhat higher level than the portion 1 andis adapted to receive the empty cars from the cage and to discharge the same by means of suitable switches to a point where they can be hauled into the mine. Each of these tracks is rovided with a car lift comprising a movab e track section 3, which, in the present instance, is shown as pivotally connected at one end near the end of the elears, of which the following is a vated portion 2 of the track and has its forward end extending between the side members of a suitable frame 4, within which it is capable of a free vertical movement. The

forward end of the movable track section 3 is preferably bent at an angle to the main portion thereof so that, when the track section is in its lowermost position, the forward portion 5 will lie in a substantially horizontal position and in alinement with the short track section 6 leading from the hoisting shaft. .This movable track section is elevated by means of suitable cables 7 secured at 'one end to' said track section and extending upwardly over suitable pulleys 8 mounted at the upper end of the frame 4 and secured at their opposite ends to suitable power mechanism, which, in the present instance, consists of afiuid cylinder 9 having a suitable piston 10 and piston rod 11, to the upper end of which the ends of the cables are secured. Each track is also provided. with a suitable hoistin cage mounted in the hoisting shaft 12. T 's cage, in the present instance, comprises a latform 13 carrying the rail sections 14,whic ,when'the cage is in its lowermost osition, are adapted to register with the rails 6 of the track. This platform 13 issupported upon a suitable base 15, by means of braces or supporting arms 16.

The hoisting cage may be actuated in any suitable manner, it being here shown as rovided with hoisting rods or cables 17 wlich are secured at their lower ends to the base 1 of the cage and extend upwardly to suitable hoisting mechanism. Mounted in the hoisting shaft 12 beneath the hoistingcageisa landing .latform adapted to receive the cage, which p atform is preferably movable within the shaft and adapted to operate the movable track sections, as well as cushion the descent of the cage. In the present instance, this landing platform comprises a frame 17 of a size and shape conforming substantially to the interior of the hoisting shaft, and has near its central portion a supporting member or platform 18 adapted to receive the base 15 of the cage. This platform is provided with a downwardly extending standard or su port 20 which is adapted to reciprocate within the fluid cylinder 21 and form a piston tl'iercfor. This cylinder has extending from a point near its lower end a pipe 22 which serves to connect the same with the upper end of the cylinder 9 of the oar-lifting mechanism of the 6O understood from the foregoing descri tion downward movement of the'landing lat-v form under the influence of the wei ht the the cage is removed from the landing platcage and the empty car thereon w' be sufficient to force the fluid from the cylinder 21 through the ipe 22 to the cylinder 9 and thus actuate t e piston 10 to elevate the movable track section of the other track. And inasmuch as the track section 3 is greater in weight than the landing platform, the track section will descend as soon as the weight of form and thereby cause the landing pla orm to again assume its normal or uppermost positionin readiness to again receive the descending cagei It will further be apparent that, inasmuch as the fluid must escape slowly from the cylinder 21, the descent of the cage with the empty car will'be gradually checked, thereby obviating all jar or jolting of the same. Suitable means are also rovided for controlling the passage of the cars from the track 1 to the hoisting cage. This mechanism, as here shown, consists of a piv-' oted rail section 23 having its forward end bent at an angle to the body portion thereof,

- as shown at 24,- and its rear end or main por- 1 track position slightly inc tion ivotally connected to an arm 25, preferab y by means of a pin or bolt 26 extending through an elongated slot 27 in the upper end of that arm. The lower end of the arm 25 is.

pivotally connected to thelanding platform, as shown at 28. Thus, it will be seen that when the landing platform is in its normal or elevated position, the main portion of the pivoted track section 23 will be elevated and the ortion 24 will be in alinement with the Land will receive a loaded car therefrom, the forward movement of the car being checked by the upwardly inclined portion of said track section. As thecage descends and de resses the landing platform, the track 22 wifi be moved about its ivotal center and the main ortion thereof rought into a substantially orizontal osition, preferably to a lined toward the cage, thereby allowing the car to move off of the same'and onto the cage. In order to prevent the cars on the track 1 from advancing too far while the forward portion'24 of the track section 23 is elevated, a suitable sump guard is provided, which, in the present instance, consists of a curved bar or arm 29 secured at its upper end to the rail section 24 and ada ted at all times to occupy such a position t at it will form a stop for the cars on the track 1. This arm 29 is preferably provided with a suitable brace 30 extending from the lower end thereof to the track section 24. Y

The operation of the device will be readily and it will be apparent that, when the anding platform is mits uppermost or normal position, the portion 24 of the cager or pivoted track section 23 will be in a position to receive a loaded car thereon, and, as the cage with the empty car descends it will de ress the landing platform and the cager w1 be moved aboutits pivotal center and the main portion thereof brought into such a position as to discharge the car therefrom onto the hoisting cage, the rails of which are'now in alinement with the railsof the eager. The impact of the loaded car against the empty car on the hoisting. cage serves to push the em ty car off of the cage and onto the slightly inc ined track 6 lying beyond the same which serves to conveythe car to the portion 5 of the movable rail section 3 of the lifting mechanism, which rail section is now in its lower most position inasmuch as the cage'of the other 'orsecond track is elevated and the movable track section ofthe first-mentioned track is free to assume its lowermost or normal position. When the loaded car is in position on the. cage, the cage is elevated, thus moving the eager 23 into posi tion to receive another car and also ermitting the pivoted track section 3 of t e second track to elevate the landing platform of that track to its normal position, and, as the cage of the second track descends, it will do ress the landing platform of that track ah the movable track section 3 of the, first-mentioned track with the empty car thereon will be elevated and that car discharged onto the track 2 and thence, b means of suitable switches,'to a position rom which it can be hauled back into the mine. I

I wish it to be understood that I do-not desire to be limited tosthe exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.
