Application December 6, 1937, Serial No. 178,381

3 Claims.

This invention relates to dumping buggies employed in mines for the loading of mining cars and of the character set forth in my application filed January 6, 1936, and Serial No. 57,819, allowed January 19, 1937. The present invention has for the primary object the provision of an improved buggy gate and mounting therefor on the buggy which will assure against accidental opening of the gate until positively released on the buggy reaching a position for unloading into a mine car, and which will permit free movement of one of the operating cables of the buggy sweep which extends through the body of the buggy.

With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a fragmentary sectional view showing a mine outlay including an aisle through which a mine car operates and a lateral in which the present invention operates.

Figure 2 is a top plan View, partly in section, ilustrating the same.

Figure 3 is a fragmentary vertical sectional view showing the buggy with the sweep located at one end of the body and the tail gate in closed position.

Figure 4 is a view similar to Figure 3 showing the sweep moved to the opposite end of the buggy body and the tail gate in a released position.

Figure 5 is a sectional view taken on the line 5-5 of Figure 3.

Figure 6 is an end View illustrating the tailgate in a closed position.

Figure 7 is a view similar to Figure 6 showing the means of securing the tail gate in closed position and being acted upon to release the tail gate.

Figure 8 is a fragmentary horizontal sectional View showing one end of the buggy.

Figure 9 is a plan view showing the driving mechanism for the operating cables of the buggy.

Referring in detail to the drawings, the numeral I indicates an entry of a mine and 2 a lateral extending from said entry. Mine cars operate in the entry, one of which is indicated by the character 3. In order that the mine material obtained at the inner end of the lateral 2 be conveniently and quickly conveyed to the car 3, a buggy 4 is employed which travels upon a track 5. The track 5 extends into the aisle l and is supported by a trestle 6 and the rails of the track above the trestle are bent upon themselves to form a buggy stop i. The buggy Stop 1 is located in close proximity to the position occupied by the mine car and in a plane above the lateral so that when the buggy engages with the stop one end thereof will be disposed directly over the car 3. Said end of the buggy is equipped with a tail gate 8. A hinge 51 connects the tail gate 3 to the buggy and is of a type which will permit the tail gate to have a vertical movement as well as a swinging movement. Locking plates [0 are secured on the tail gate and each include spaced projections H and I2. The projections l2 are slightly longer than the projections H and extend through notches formed in the body of the buggy while the pro-' jections l are received in recesses formed in the body of the buggy. The projections fitting in the openings and recesses as described will secure the tail gate against both swinging and vertical movement. The tail gate 8 is constructed of a pair of sections the adjacent ends of which are spaced to permit free passage through the tail gate of an operating cable l4. One end of the operating cable is connected to a sweep l5 slidably mounted in the body of the buggy. The other end of the operating cable is connected to a drum of a power driven mechanism' l6 including a clutch mechanism. The mechanism l6 also has connected thereto an operating cable IT. The operating cables pass over pulleys 18 carried by the trestle 6 and the operating cable ll is further passed over a pulley 89 located at the inner end of the lateral 2. The operating cable after passing over the pulley I9 is secured on the sweep [5. The sweep is free to slide from one end of the body of the" buggy to the other. The means employed for slidably mounting the sweep is of any conventional construction such as reduced portions of the sweep extending into guide grooves [9' formed in the sides of the buggy body, the ends of the grooves acting as stops to prevent the sweep from moving out of the ends of the buggy body.

Gate trip bars 2! are included in the structure of the trestle 6 and project upwardly and forwardly from the trestle and terminate within the aisle 1 over the mine car 3 and provide supports for certain of the pulleys which support the operating cables. The inclination of the trip bars is such that when the buggy 4 reaches a position for unloading into the mine car 3 they will have en,- gaged the extensions 12 of the locking plate to impart vertical movement to the end gate. The bug y having been stopped by engaging the stop 7 with the operating cable [4 continuing its driving action causes the sweep to travel the length of the buggy body and remove therefrom the load into the mine car. It is to be understood that the sweep l prior to loading the buggy is positioned at the end of the buggy remote from the tail gate and retains this position when loaded as long as the tail gate remains latched due to the load in the body being between said sweep and the tail gate. It is to be understood that the cable ll draws the buggy into the lateral while the cable I 4 acts to draw the bu y out of the lateral into engagement with the stop 1 and to bring about movement of the sweep I5 endwise of the buggy body as soon as the tail gate is released and the buggy engages the stop, which causes the load in the buggy to be displaced into the mine car.

Secured to and extending at right angles from the sweep l5 are rudders J5 acting as mediums for connecting the operating cables 4 and IT to the sweep. The rudder which lies within the buggy will be engaged by the mine material in the buggy and will act as a stabilizer for the sweep as the same is drawn endwise of the buggy for the purpose of unloading the same and thereby prevent cooking of the sweep in the buggy and consequently eliminate binding of the sweep so that the same will freely slide from end to end of the buggy. The placing of rudders on each side of the sweep will permit reversing the sweep in the bug y.

Whatis claimed is:

1. A dumping buggy comprising a track located in a mine lateral and having at the mouth of said lateral, rails of the track bent to form a buggy stop, a buggy operable on said track and including a body open at each end, a sweep slidable in said body from one end to the other and normally occupying a position at one end of the body, a tail gate mounted on the body for closing the other end thereof and capable of swinging and vertical movements, latch plates secured to said gate, projections on said latch plates and the projections of each plate varying as to length, said body having notches and recesses to receive the projections for releasably securing the tail gate in closed position with the longest projections extending below the body, means connected to the sweep for causing movement of the buggy in either direction over the track and to bring about movement of the sweep from one end of the body to the other end thereof when the stop is engaged by the buggy, and means to engage certain of the projections to release the tail gate by imparting a vertical movement thereto to move the projections cut of their respective notches and recesses.

2. A dumping buggy comprising a track located in a mine lateral and having at the mouth of said lateral, rails of the track bent to form a buggystop, a buggy operable on said track and including a body open at each end, a sweep slidable in said body from one end to the other and normally occupying aposition at one end of the body, a

tail gate mounted on the body for closing the other end thereof and capable of swinging and vertical movements, latch plates secured tosaid gate, projections on said latch plates and the projections of each plate varying as to length, said body having notches and recesses to receive the projections for releasably securing the tail gate in closed position with the longest projections extending below the body, means connected to the sweep for causing movement of the buggy in either direction over the track and to bring about movement of the sweep from one end of the body to the other end thereof when the stop is engaged by the buggy, and fixed inclined members arranged adjacent the stop to contact certain of the projections on the buggy nearing the stop to bring about vertical movement of the tail gate to permit swinging movementof said gate caused by the sweep moving from one end of the body to the other end after the engagement of the buggy with the stop.

3. A dumping buggy comprising a track located in a mine lateral and having at the mouth of said lateral, rails of the track bent to form a buggy stop, a buggy operable on said track and including a body open at each end, a sweep slidable in said body from one end to the other and normally occupying a position at one end of the body, a tail gate mounted on the body for closing the other end thereof and capable of swinging and vertical movements, latch plates secured to said gate, projections on said latch plates and the projections of each plate varying as to length, said body having notches and recesses to receive the projections for releasably securing the tail gate in closed position with the longest projections extending below the body, means connected to the sweep for causing movement of the buggy in either direction over the track and to bring about movement of the sweep from one end of the body to the other end thereof when the stop is engaged by the buggy, fixed inclined members arranged' adjacent the stop to contact certain of the projections on the buggy nearing the stop to bring about vertical movement of the tail gate to permit swinging movement of said gate caused by the sweep moving from one end of the body to the other end after the engagement of the buggy with the stop, said gate including sections having adjacent ends thereof spaced to permit a part of the operating mechanism of the sweep to extend through the gate and into the body of the bug y.
