I well )Wll that mine cars alter learing llie eh; i the mine run 021 tracks in 2!. suitable pal-5m 0f discharge Where they are emptied usually by means of an ordinary tipple. In elllpljl'il' fg the Cili'i'zl in this mam ner, one eml'ie pl'OfltlGil will ;i movable door which is opened when the car has run on the ti'nple and been inclined. Ordinarily this (1100? cannot be unlocked unlzil the ear is'inelinecl because of the fact that the weight if the c6111 will force the same open. With my invention, the (leer he released 01' unleicl'ied While the ear is still on the horimm portion of the track, and before it reaches the iipple, said. door remaining closed until it is inclined and lillG coal forces the slime epen.

In carrying milthis elojecl: I have provided in ordinary mine car designated in the drawings by llie numeral 1, with an improverl (leer etruellm'e which will be more particularly described later The car has lie usual sides 2, b0iiem or floor 3, and runing 4:, the Wheels of the letter ruhniiig cm ordinary lmelis purtien of the t-ipple is shew); in 3;, 4, end 5, and

The shell 1 and lzlie cranks 14 may be farmed Q? t 2 same bar if desired, and the upright pore-mes 15 0f the drunks are dismfi the ends 0f she portion 8 of the deer, iiie emls of the latter being cul, away as slimvn at 16 to receive the same. The liorimrlml parts 17 of the cranks are jeurneleil l0 ll e sides 2 0f the cm, angle metal brackets 18 being secured its the upper edge (if the sides for this purpese. The horizontal flanges of these angle'brackets are recessed adjacent one end as shown at 19 to allow the cotter pin 20 or other retaining means carried by the cranks to clear said flanges.

From this description it will be seen that since the door 7 is rotatably mounted on the shaft 13 and the cranks of the latter are journaled in the angle brackets 18, said door tain thedoorin the position shown in Figs.

1 and 2, a pair of hooked fingers 21 is provided, one being disposed on each end of a rock shaft 22. The rock shaft is journaled in suitable bearings'adjacent the top of the door 7'and the fingers are disposed beyond the ends-of the portion 8 so that when the shaft is rocked in one direction the fingers 'will-bedisposed in engagement with the horizontal portions'17 of the cranks. They are normally retained in this position by the weightof a depending handle23 which is formed on the rock shaft. The handle 23 is retainedagainst accidental movement by means of a pivoted latch 2i in the form of a lever. One end of said lever which forms the handle isheld in operative position by means of a hook or the like 24. The rock shaft 22is also provided with a pair of collars 24 which are fixed thereto and 'disposed one adjacent each of its outermost bearings which, in the present instance, are formedby the straps 11. These collars prevent longitudinal shifting of the rock shaft and hold the hooked fingers 21 in proper relation to the cranks with which they co operate.-

From the several figures it will be seen that the structure which has just been described is all disposed adjacent. the top of the door 7. In order to hold the bottom portion of the door against outward movement additional catches in the form of fingers 25 depend therefrom and cooperate with seats on the bumper 26 of the car. The fingers25 are preferably formed by extending the outer straps 11 below the bottom edge of the door as'clearly shown in Figs. 2, 4, and 5. These seats are formed by right angular members 27 constructed of angle metal and are secured by their horizontal flanges-28 to said bumper 26 or the adjacent parts of the car. ()ne arm of each right angular member 27 is disposed inwardly while the otheris disposed longitudinally of the car as shown in Fig. 6. It is between the upright flanges of the first mentioned arms and the edge of the floor 3 that the fingers 25 are disposed.

The operation of the door structure hereinbefore described, assuming that the car upon which it is mounted has been loaded with coal, is as follows: The loadedcar is run on its tracks 5 until it reaches a oint 'adjacentthe tipple (5, whereupon the latch 24 disengaged from the handle. 23, thus permittingv the rock shaft to rotate inorder to release the hooked finger-s21 from the cranks 14, which are held against movement so long as the handle 2-! is down in the posi-, tion shown in Figs. 1 and 2. not begin to open, however, after the latch' 24 has, been released until the car has reached ,the tipple and been inclined as shown in Figs. 3, 4, and 5. This inclination causes the coal in the car to move by gravity against the door 7, and since the lower edge of the door is held by the fingers 25, the upper part will be .forced outwardly as shown in I ig. 3, the cranks l4 readily permitting this outward movement. The continuous pressure of the coal on the upper outwardly until the fingers 25 are forced clear of their seats, whereupon the coal forces its way between the lower edge of the door and the bottom of the car. The door is now carried by this movement of-the coal upwardly and outwardly around the shaft 13 and by the cranks lijinto the positions illustrated in Figs. -l and 5, Fig.5'showing the door opened to its fullest extent. The outrushing coal retains the door thus until the car is completely emptied, whereupon it is moved by gravity into more of a vertical position.

After the car has been emptied and moved off of the tipple onto its horizontal tracks the door may be readily closed and locked by'first inserting the fingers 25 in their seats,

' the upper portion of the door 7 during this movement being inclined outwardly. The upper part of the do r isthenmoved inwardly until it is substantiallyvertical or until the outer ends of the rock shaft engage the horizontal portions 15 ,of the cranks.

The rock shaft is next rotated so as to dispart of the door gradually forces the samepose'the hooked fingers2l in engagement with the horizontal parts of the cranks, the handle 23 being then disposed downwardly so that it may be engaged by the latch 24. From the foregoing description taken in connection with t e accompanying drawings, it is obvious that I have invented a much improved mine car door which ma be operated very efliciently. The siinpli the construction will allow the same to be manufactured. rather inexpensively. It is unnecessary to build a specially constructed, car in order to use a door constructed in accordance with my invention, as ordinary cars already built may be readily equipped.
