IViINE-CAGE.

Application filed January 2 1 '0 alt whom it may concern: I

Be it known that 1, PAUL 1V. llons'rnin, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Mine- Cages, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to mine cages, and has for its special object to provide mechanism whereby a car can be run uponthe cage at a landing, and held more securely in position than hitherto while the cage is being lifted to the surface of the ground and there emptied of its contents.

Other minor objects will be apparent from a reading of the following specification in connection with the drawings, of which- 7 Figure 1 is a cross sectional side elevation of the mine cage in position the bottom of its shaft, andadjacent parts of the mine, F 2 is a similar cross sectional view at an intermediate landing likewise showing adjacent parts of the mine, the upper part of the cage being broken away. Fig. 3 is a view in side elevation of the cage at the upper limit of its travel and of the mechanism for dumping the mine car, the tilting platform being shown in position to discharge the contents of the car. Fig. i is a plan view of the car, one half being shown in section, with hori Zontal cross section of the shaft. ll 5 is anend elevation of the mine cage. Fig. 6 is a perspective view of the safety catch mechanism.

The cage comprises essentially two parts, the sling frame A and the tilting platform H, pivctally secured to each other at their lower ends. The sling frame can be most satisfactorily constructed of structural steel, as shown in the drawings, consisting of the vertical side channels A joined by theupper horizontal channels A and the lower horizontal channel A. To the outside faces of the channels A? are secured guide blocks B which engage with the slides C which may be wood or metal strips, to hold the cage in place laterally, while permitting freedom of motion vertically. lliveted to the top side of the upper flange of the channels A- is the yoke D through which the draw-bar l) passes. Biveted to the under side of the lower flanges of the channels A} mid Specification of Letters Patent.

way between the ends of the channels is the plate A Through a'hole in the center of this plate the draw-bar D is guided in its vertical motion. By means of the spring D surrounding the draw-bar and placed between the under side of the yoke 13- and the nut upon the drawbar, a yielding suspension is provided so that the car will be lifted without shock, and a jerky motion in the hoisting mechanism will be to a large extent absorbed.

The cage is provided with the safety device indicated as a whole by E. Mounted in brackets E carried by the channels A is theshatft E keyed to which are the toothed cams E A chain ll attached to the under side of the segmental sheaves E at one end, and at the other to the clamp 19] secured to the draw-bar D holds the toothed cams out of engagement with the slide wheneyer there is tension in the hoisting rope. When for any cause this tension is released, the spring E throws the cams into engagement with the-slide and any small descent of the car causes them to sink deeper into the slide, as they revolve about the shaft E until the cam surface impinges on the upper face of the inner surface of the housing E which is preferably cast integral with the bearing brackets E The traction block E integral with the plate E of the bracket casting, forms with the brackets a shoe which on gages with the slide and prevents the lateral. displacement of the cage, as a whole, under the side thrust of the revolving cam E The housing, E assists the shaft bearing proper in preventing the cams from turning clear over, when they are thrown into ac tion. Tightening the hoist rope will innne diately throw these cams out of engagement leaving the cage free to slide up or down.

A canopy is provided to protect workmen in the cage from falling bodies and consists of the two'plates F F which are hinged to the plate F the latter being secured to the top of the upper flanges of the channels A To the under sides of the plates FF are riveted the plates F the inner edgesof which abut against the central parts of the slin frame thus servin to hold the two sides of the canopy in horizontal position, while at the same time strengthening the canopy structure, as a whole. By hinging the canopy in this manner either of the sides can be swung into a Vertical position to per? frame. The upper ends of which are joined mit of the lowering down the shaft of rails, long pieces of timber,etc.

The bearing supporting plates G for the tilting frame are riveted to the inner faces of the lower ends of the channels A and carry the bearing blocks G in which is mounted shaft G. JPivoted upon this shaft are the vertical channels H of the tilting by the shaft H rotatably mounted therein. In this mannerthe tilting frame is secured at the bottom and a little to one side of the sling frame. Its center of gravity, as a whole, being normally in the vertical plane of'the channelsA so that the shaft H rests by the'action of gravity against the brackets H secured. to the upper end of the sling frame.

e The shaft H carries a pair of rollers H which engage with guides H located at the top of the shaft-to give the platform a forward movement when the sling frame is a raised vertically sothat the contents of the car carried'by the platform may be discharged. The guides are curved, as shown in the drawings, in such a Way that this dumping movement is gradual and takes place Without shock tothe car. The vertical,

boards H ,-v\'l1ich form a continuation of the upper ends of the guiderails H cause the car to be maintained at the same tipping angle, 6;, about 45,if the sling'frame is raised above the tipping plate. I

Riveted to the channels H neartheir lower ends are the channel beams H which are braced thereto by the plates H and the diagonal struts H The mule guard plates H 9 are secured to the channels H and the struts H The channel beams H with the end channels H and the central l-beam H form a horizontal framework upon which the car-supporting tracks 1 and floor boards J are supported. The latter are suitably secured to the end channels H upon which they rest. The tracks I are made in two sections, as shown,each section being hinged at its outer end to the end channels H by means of the bearing brackets M secured thereto, the shafts I mounted therein and the plates M hinged to the shaft, and riveted to the rails. The two rails of each section of the track are connected together by the channels N riveted to the. under side of the rail-flanges and braced by the plates N Also riveted to the under side of the rail-flanges are the bumpers I which rest upon the upper face of the I-beams I hinged at one end to the shaft 0 mounted in the brackets secured to the inner faces of the end channels H". Three other tie-rods O serve to connect and hold in rigid relation to each other the channel beams along the remainder of their length. These channel beams are thus free to swing upon a horlzontal axis through the small angle ll111 ited inan' upward direction by the channels H and I-beams H and in a downwardydirection by the stirrup i suspended from the central I-beam I- When therefore the mine cage is at the bottom of the shaft, as

ing upward if these levers K have been inadvertently-left in operative position, they will automaticall be thrown out-of the path of travel of the cage. On the other hand, if the cage is descending and if by the lever K the levers K have been thrown into operative position the channels'l will be swung upward relatively to the channels I and in contact therewith, so as to elevate the tracks to a horizontal position.

When the mine car Q has been moved on to the cage and the cage begins its ascent,

the track sections swing about their pivotal Y supports until their inner ends rest upon the lower flange H of the central I-beam H? and the car, as a whole, is lowered relatively to the cage until the axles Q or any other suitable projection of the car settles into the notches 1 formed in the skids 1 until the body of the car rests upon the skids. These skids aresecured to the platform boards J. By this simple expedient the car is securely maintained in position upon the tilting platform, while the latter is being moved up and down the mine shaft and when it is being tipped at the surface of the mine without putting any strain upon the car wheels, or running gear.

in order to stop the car upon the tilting platform exactly that point where the car axles will be directly above the notches T the latch 11 notched to receive the downwardly projecting part of the L-shaped lug L attached to the bottom 'ofthe car, is pivotally mounted in the latch carrying block L This block is free to slide longitudinally in suitable g ideways formed in the base block L, which is secured to the platform boards. The block L is held in position at one end of its'range of movement by the spring L" which takes the shock of the sudden contact of the lug L of the moving car with the latch L. The latch L is normally held in engagement with the l g by the spring L acting throu h the rod L lever L and the arm L keyed to the shaft L on which the latch is rigidly mounted. At the lower landing the tagger R is installed consisting of the arinlt keyed to the rock shaft'lt to which is also wheel keyed the arm It"; This arm contacts with the end of the rod R, which is suitably mounted on the mine floor, and is provided with the bumper R adjacent to and in line with the bumper L on the end of the rod If. A spring It holds the bumper B normally away from the bumper L An oncoming mine car automatically operates the tugger It, and through the rod If and lever If, releases the latch L, leaving the car on the cage free to move off which it does when the oncoi'ning car strikes itsbumpers. The oncon'iing car is then caught by the latch and held in position on the cage.
