To aZZ whom t may concern.'

Be it known that l, VILLIAM D..MO0N, a citizen of the United States, residing at Blocton, in the county of Bibb and State of Alabama, have invented certain new and useful Improvements in SafetyStops for Mine- Cars, of which the following is a'specifcation, reference being had to the accompanying drawings. i

`This invention relates to improvements in safety devices for mine cars or cars moving upon inclined surfaces and the object of the invention is to provide means whereby the car may be stopped or derailed when upon an incline and if the hoisting cable breaks or for any other reason the car moves backward. I

A further obj ect of the invention is to provide drag bars adapted to bel detachably mounted upon the draw bar of the car so that the drag bar attachment may be shifted to the rear end of the car or the last car of a train of cars.

A further object is to provide an attachment of this character wherein the drag bars cannot get under the car in casey of a wreck and in which the drag bars are so formed that they can never rise too high nor extend out too far to either side.

A further object is to provide a construction of this character in which the drag bars will straddle the usual rollers on which the `cable is supported so as not to foul the cable.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein- Figure l is a plan view showing my drag i bar'applied to a mining` car;

Fig. 2 is a side elevation of the structure shown in Fig. l;

Fig. 3 is a longitudinal sectional view through a portion of the draw bar and through the socket member 10; and

Fig. 4 is a section on the line 4 4 of Fig. 3.

Referring to these figures A designates the ordinary track upon which the cars are supposed to run, this track being at an incline. The track is supported upon the usual ties B carrying the usual rollers C. All of these parts are ordinarily found in tram roads for mines. Operating upon the rails A is the car D or train of cars. Each of the cars D is provided with the usual draw bar E.

Specification of Letters Patent.

Patented Feb; 27, 191'?.

My invention consists of a .rectangular casing l0 which is open at opposite ends and isadapted at one end to fit over the 'draw bar E and be held in place thereon by the pin 11 which passes through perforations'in the upper and lower walls of the casing 10.

The side walls of the casing 10 are formed with openings for the'passage of a transverse pivot pin 12 and pivotally mounted upon this pivot pin 12 are the drag bars 13.` These bars extend outward and laterally at a su'iicient inclination to a vertical plane-passing through the axis of the cars so that the eX- tremities of the barswill not strike the rollers C but will travel fon each side of these. rollers. its rear end is cut away as at 14, the purpose of which'is to allow the drag bars to incline downward at a proper angle so as to ride over the ties. Inasmuch as the casing 10 projects beyond the forward edge o-f the cut Laway portion 14, it is obvious that the drag bars will be prevented fro-1n rising too high l and that the side walls of the casing prevent the drag bars from spreading toomuch.

lThe under face of thecasing 10 at r.The boX or casing l0 ismade of material y which may be bent and the drag bars may also be bent and in this way the device may be made adjustable to`4 any height of car. The drag bars 13 are-always dragged lightly over the surface of the ties and ycan never get too high or too far out to either side. The ends of the drag bars travel laterally of the outer ends of the rollers C but inside of the rails.

With a drag constructed in accordance with this invention, the drag bars can never get under the car incase of wreck because the box or casing l() will only Vpermit the drag bars to be depressed to a certain angle and further than this they cannot move unless something breaks. The drag, as it is obvious from the drawings, is at all times in place to do its work and cannot get out of place. It will not knock the rollers C out of position and permits the drag rope or cable by which the car is moved to travel on the rollers and this keeps the rope from dragging on the ties.

Immediately upon thetrip breaking and the car starting to run backward down the slope, this drag will either stop the cars on the rails or derail the rear' carto which it is attached and the derailed rear car will stop all the remainder of the cars of the train loV and keep them from being broken up, keep the timbers of the mine from being knocked out, and prevent casualties t0 the men Yand mules.

lt will be readily removed from one car and placed upon another and that it may be readily removed when the car is moving down a slope. Of courseV it is ob vioiis that the drag bars may be made as heavy as desired but they should not be of greater strength than the draw bar. lt will be seen from the drawings that the drag bars 13 are slightly curved downward with points beveled or made sharp so that they will easily stick either in wood Or dirt. twill be seen that the drag bars will not come in contact with the rollers C not only because the drag bars are spaced at their'rear ends aV distance greater than the length of the rails but for the reason that the drag bars will pass over anything that the car axles will.

VHaving described my invention, what l claim is:

l. A safety attachment for mining cars comprising a casing adapted to receive and engage with the rear end of a draw bar, and a drag bar pivotally mounted in the rear end of the casing.

2. A safety attachment ior mining cars comprising a socket member adapted to fit over the end of a draw bar and be detachably connected therewith, and rearwardly divergent drag bars pivotallymounted for vertical movement in the other end of the socket member. Y

3. A safety attachment Vfor mining cars comprising a socket member adapted to fit over the end of a draw bar and be detach- Copies of this patent may be obtained for be seen that my attachment mayV ably connected therewith7 and rearwardly divergent drag bars pivotally mounted for Vvertical movement in the other end of the socket member, the under side of the socket member being cut away at lits rear end to permit the drag bars to extend downward and rearward, the top of the socket member preventing too great upward movement of the Vdrag bars. Y

Safety attachment for mining cais comprising a socket member adapted to be disposed over the end of a'draw bar and det-.reliably connected therewith', and' rearwardly divergent Vdrag bars pivotally mounted in the rear end of the socket member for independent vertical movement.

5. AV safety attachment for mining cars comprising a socket member rectangular in cross section and relatively shallow and adapted to be disposed over and engaged with the rear end of a draw bar, the socket member having perforations in its upper and lower walls for the reception of an at- Y taching pin to the draw bar, the bottom oi? the socket member at its rear end being cut away so as to be shorter than the top and the side walls of the socket member at its rear end being perforated, a pivot pin passing through the last named perforations, and divergently disposed drag bars pivoted upon said pin and having limited vertical movement within the socket member.

In testimony whereoil I hereunto aiiix my signature in the presence of two witnesses.
