1 Claim.

adapted for use in mines for loading coal, ores,

etc.

The principal object of the present invention is to provide means whereby mined material can be easily loaded onto mine care, where the workings are in a direction-laterally of the car tracks.

Another important object of the invention is e loading means of the character stated which will be easy to operate and which will require a minimum of man power.

These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:-

Figure 1 represents a horizontal sectional view through the workings of a mine showing in plan the tracks and a lateral working area in relation thereto.

Figure 2 is a vertical sectional view through the mine showing in side elevation the loading apparatus.

Figure 3 is a fragmentary vertical sectional view through the loading apparatus.

Figure 4 is a plan view of one of the pans.

Figure 5 is a side elevational view of one of to provi-d the pans.

Figure 6 is a cross sectional view taken substantially on the line 6-45 of Figure 4.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 denotes the tunnelway through which the tracks B of the mine car system extend. Numeral 7 denotes a side working laterally of this tunnel 5 and into which the loading mechanism protrudes as is clearly shown in Figure 1.

This loading apparatus consists of an elevated frame mounted upon the posts 8 which maintain the frame Tl elevated above the tracks 6. This frame F is so elevated as to permit the cars 9 to avoid the same as they pass thereunder and when loaded.

Xtending downwardly from one end of the frame I is the ramp l0 along which can be pulled the pans As shown in Figure 6 each consists of a shallow box-like structure having side walls l2-I2 and end walls l2-I2. The

of the pans ll The bottom sections l3l3 are equipped with runners As is clearly shown in Figure 2,

over each of the trackways 6 the frame I i has a pair of hingedly mounted plates MM which are limited in their downward disposition by chain sections [5. This forms a chute for guiding the mined material into the cars 9 and also serves to close the bottom sections as the pan is pulled from over one track to the other.

Each end of the pan II has a boss l6 apertured to receive the corresponding end of the cable ll. This cable extends from one pan over the frame I and pulley [8 to the double Windlass drum 19 mounted upon the floor of the mine. The cable extends backwardly under the trackways 6 and is guided by the pulley 28 to a'point laterally of the pan being filled where it passes around the pulley 2| to attach to the pan being filled.

It can now be seen, that when the Windlass drum I9 is operated, the pan II which has been filled, is pulled up the ramp l0 and as it rides onto the frame I, the bottom sections l4 are released so that the contents of the pan are released into the underlying car 9.

Reverse operation of the Windlass drum will return the pan which can be detached and the other pan now loaded can be attached to the cable.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to Without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what claimed as new is:-

Loading apparatus for use in mines comprising an open elevated frame, a ramp extending to the top of the frame, a pan having a downwardly opening hinged bottom, and means to pull the pan up said ramp onto the frame, said frame having thereon in the path of movement of the pan a plurality of pairs of downwardly inclined gates forming open bottom hoppers below the pan for the discharge of contents of the pan therethrough selectively and providing for downward opening of the bottom of the pan when the latter is located over the same, said pairs of gates acting under movement of the pan in 0-pposite directions, respectively, from such location to cam said bottom of the pan into closing position, the gates being hinged to the frame for upward swinging movement into closing position.
