CAR-FEEDING DEVICE .FOR CAGES.

To all whom it may concern:

Be it known that we, CHARLES E. Bnoons and CLARENCE GATES, citizens of the United States of America, residing at Bowerstown, in the county of Harrison and State of Ohio, have invented certain new and useful-Inn provements in Car-Feeding Devices for -Cages,

of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a car feeding de vice for cages that are operable in mine shafts for elevating pit cars from a room or entry of a mine to a tipple above the mine shaft.

Our invention aims to provide:First,positive and reliable means, as hereinafter set forth, for retaining a pit car upon a cage while the same is elevated and tilted to discharge the contents thereof. Second, a feeding mechanism that is automatically actuated by a pit car to release the locking mechanism of the cage, whereby the empty car upon the cage can pass off and a loaded car pass thereon; Third, a car feedin mechanism adjacentto the lower endo a mine shaft that is actuated by a cage to release a' car held in check, whereby the car can move toward and onto the cage. Fourth, a pit car locking and feeding mechanism consisting of comparatively few parts, inexpensive to manufacture, and easy to install in connection with the track and the present type of cage. Fifth, a mechanism of the above type that is positive in its action, not liable to injury by ordinary use and highly efiicient for controlling the passage of pit cars or other types oicars on to and oli' of cages, elevators and movable bodies. I

Our invention further aims to accomplish the above results by a combination of mechanical elements that will be hereinafter specifically described and then claimed.

Reference will now be had. to the drawings, wherein like numerals denote corresponding parts throughout the several views, in which Figure 1 is a plan of the car feeding device, and .a cage, Fig. 2 is a side elevation of the same showing a portion of the cage, Fig. 3 is a plan of the locking mechanism showin the same in an actuated position, Fig. 4 18 a cross sectional view taken on the line IV-IV of Fig. 3, Fig. 5 is a similar view taken on the line V-V of Fig. 3, Fig. 6 is a similar view taken on the line VI--VI of Specification of Letters Patent.

Fig. 3, Fig. 7 is a similar view taken on the line VII-VII of Fig. 1, Fig. 8 is asimilar view taken on the line Vill -VIN of Fig. 1, Fig. 9 is a similar view taken on the line TXIX of Fig. i, and Fig. 10 is perspective 'view of the feeding mechanism. In describing our invention by aid "of the drawings above referred to we desire to point out that we intend I merely illustrative of an example whereby our invention may be applied in practice, and we donot limit our claims to the precise arrangement and consirimtion of parts indicated, and the following description is therefore to be construed broadly as including substitute arrangements and constructions which are the obvious equivalents of those shown.

i The drawings show a truck having the rails 1 and Q longilmlinnHy alining with rails 3 and 4 respectively arranged upon a cage or elevator The cage or elevator is of the ordinary and well known construction operable in a mine shaft and capable of being elevated and tipped or tilled between guidcs'ti by a suitable hoisting mechanismforming no part of this invention.

said device as 7 denotes longitudinally alining bearings carried by the cage 5 and mounted inthese bearings, at the outer sides of the l'tLllSt,

.are longitudinal pivot rods 8. Pivoted-upon the rods 8, at 'one end thereof, are the barrels 9 of oppositely disposed stops or check members 10 capable of swinging over the rails 4, as shown in Fig. 1. The barrels 9 are provided with cranks 11, and pivotally connected to said cranks are the ends of a groove 13 provided therefor in the cage reach rod 12 that extends lengthwise of a The reach rod 12 is employed whereby the stops or members 10 can ,be moved in um son.

Pivoted upon the rods ends thereof, and spaced apart from the stops 10 by longitudinal sleeves it are looking members 15, similar to the stops 10 but arranged in reverse order. The locking anembers .15 have depending curved cranks .16 extending through openings 17 provided therefor in the cage 5 and the lower ends of said cranks have weights or enlargements 18 that support the locking members 15 in a normally closed position extending over the rails 4 of the cage.

19 denotes 2). depending crank, carried by one of the pivot pins 8, said crank extending S, at the opposite I rock shaft member 26, said member normally extending'over the rail 1.

" of the mechanism just The, rails 1 and 2 are Before further describing our invention, it is thought best to consider the operation described in connection with a pit car27 having flanged wheels. ata slight inclination whereby the pit-car can descend by gravity and impinge the actuating member 26. The

ends of the actuating members are curved assume their normal Wheel's are therefore held between the stops 'ing with the track of upon the cage being vacated the stops 1() whereby a wheel 28 of the car can easily ride into engagement with the same, shifting the member outwardly, and thereby rock theshaft 23. In'rocking the shaft 23, the

crank 22 of said shaft engages the crank 19 and rocks the pivot rods 8. As the sto s i 10 are mounted upon said pivot rods, said 25 stops are swung to an open "position, outwardly from the rails 4, allowing\ a car on the cage 5 to move off onto a track 2 alinthe cage. Immedi elv assume their normal position by gravity and the cage is ready to receive the car that actuated the member 26. As the forward wheels of the car engage the locking members 15, said members are swung outwardly and the. forward Wheels of the car engage the steps 10. The rear wheels of the car are then held by the locking members 15, which position. The car and the members and the cage 5 can be raised and tilted without any danger of the car becoming displaced until the cage 5 is lowered and restored to its normal position. The car is locked upon the cage until the member 26 is again actuated, as previously described. As a further guard against accidental displacement of the car, while the cage is tilted, we provide the bottom of the cage with pivoted gravity members 18 that prevent the cranks 16 of the locking members 15 from swinging. Now, as the rails 1 and 2 are at an inclination, there would be danger of cars descending when the cage is elevated, and to avoid the use. of an attendant, we have devised a feeding mechanism that is automatic and depends in operation upon the cage being lowered. This feeding mechanism is 10- catcd some] distance or a car-length from the member 26'and said mechanism is constructed somewhat uponthe principle of the mechanism of the cage.

At the outer sides of the rails 1 and 2 there are bearings 28 and 29- and rock shafts journaled in saidbearings are '30, 31' and s2,

rod mounted in each the shafts 31 and 32 emg located adjacent to the outer side of the rail 1 and the shaft 39 adjacent to the outer side of the rail 2. The shaft is of greater lcngth than either of the other shafts and extends to the cage 5 where it hasa crank 33 extending under the cage and into the path of said cage, whereby said crank will be lowered when the cage assumes its normal position, thereby rocking the shaft 30. The shafts 30, 31 and32 have cranks 34- connected by a reach rod 35 whereby said shafts will be rocked in unison.

Mounted upon the rock shaft 31 is a stop 36 and loosely mounted upon the rock shaft 30 is a stop 3.7, said stops being oppositely disposed and having cranks 38 connected by a reach rod 39.

Mounted upon the shaft 30 is a stop 40 and loosely mounted upon the shaft 32 is a stop 41, said stops being oppositely disposed and connected by a reach rod 42 whereby they will move in unison.

The rock shaft 81 has a weighted crank 43, which through the medium of connections just described holds the crank 33 normally elevated in position to be impinged by the cage when descending.

By mounting some of the stops on their respective shafts and loosely mounted on others, the stops 36 and 37 can be shifted the reverse of the stops 40 and 4.1. Thcstops'i-ltl and 37 extend normally over the rails l and 2 thereby holding a car in check. \Vhcn the crank 33-is lowered the stops 36 and 37 are swung outwardly and the stops 4-0 and 41 are swung inwardly. The car hcld incheck by the stops'36 and 37 can descend, actuate the member 26. and pass onto the cage without any dangcrof other cars dcscending and causing an acident. \Vhcn the cage is elevated the crank 33 is released, the stops 36 and 37 swing inwafllly and the stops 4.0 and 41 swing outwardly, thereby allowing another car to'desccnd against the stops 36 and 37 in position to pass downwardly onto the cage, when the cage is j lowered. It is therefore apparent that for- -a successful operation of the feeding mechanism a cage must housed and that cars could not automatically pass onto the cage without using the feeding device. Both devices cooperate for obtaining a very important result, and we would have it understood that with certain modifications and variations our invention is applicable to gravity railways, feeding onto elevators or. hoists.
