The invention relates to new and useful improvements in mine cars adapted for use in what are commonly known as low vein mines,-that is, mines in which the seam is relatively thin and a few inches inthickness from top to bottom,-though it is adaptable Jfor `use in other places by mere change in dimensions.

As shown in the drawings, the car is designed primarily for use in a cradle dump, though with slight modification within lthe disclosure ofthe prior a rt an end gate may be substituted for either 'of the end walls shown and the car used in a tipple or end dumping device.

Fig. 1 is a side elevational view of a mine car embodying the present invention;

Fig. 2 is an inverted plan view of the major portion of said car; and

Fig. 3 is a transverse vertical sectional Viewv taken on line 3 3 of Fig. 2. t

Referring to the parts, it will vbe observed that the car oor comprises planks "5,l 6a and 7a intermediate the angle sills 13 and 14, which planks and sills rest upon the bolsters 18a which in turn rest upon and are secured to conventional journal or axle boxes 50 (see Fig. 2) through which the axles 21 extend; said axles terminating in the wheels 20, as in -usual in this type of construction. As shown, the holsters 18a are of channel section, and thus serve as axle housings. The planks 5, 6", 7a are secured to the holsters 18aL by' bolts 51 which pass through the horizontal web portions 52 of said holsters. Besides tlieplanks 5a, 6a and 7 in the center, the floor also includes planks 5", 7", and metal plates 18", outside the sills 13, 14. At their outer sides or edges, these outer floor portions may be reinforced with side sill angles 36.

Manifestly, the wheels 20. which are intended to run on the conventional tracks, support the axles 21, which in lturn support the journal boxes 50; and the journal boxes -underlie and support'the longitudinal sills or angles 13 and 14. These 13 and 14 not only perform the usual function of sills, contributin to the support of the iloor between and yond the axles 21, 21, etc, but they also extend beyond the ends of the car body and serve as stieningmembers for bumpers or buffers 10, 11 formed by extended end portions of the floor, which portions enclosed between the projecting ends of said members 13, 14. The bumpers 10, 11 are shown as of conventional type, comprising the ends ofthe door boards 5, 6a, 7 beyond the car body, the'fller members A, and the sheet metal sheathing 12, which laps said parts and is secured to them by through bolts or other connections (not shown). The fillers A are backed'` up and stifened by abutments formed by transversely extending angles B, secured to the under side of the car floor and also riveted to the angle sills 13, 14. Accordingly, the sills.13, 14 assist the buffers 11, 12 in taking end shocks when cars are coupled together.

As shown in Fig. 3, the angles 13, 14 lie in the longitudinally extending floor plank- `ing with their vertical' flanges 13.a and 14a interposed between adjacent planks and the flanges 15a and 16 being gained ,into the bottom portions of some of the planks. It will be observed lthat between the wheels of Figure 3 there are three planks 5a, 6" and 7a shown, with portions of other planks 5" and 7", and that the stiening angles 13 and 14 are interposed between the planks 5a and 5" and the planks 7'i and 7".

It will be observed that if extended in a single plane, the side portions of the door including the planks 5" and 7" would intersect the upper portion of the car wheels, but that the plates 18" are pressed upwardly to clear said wheels. It will be seen, therefore, that the car floor consists essentially of a main central portion or section, reinforced and stiffened by the sill angles 13, 14, and equipped with the central buffers-10, 11 at its ends, and also side sections extending outward from said central section, with which side sections are combined the wheel hood sections 18".- The normal plane of the side floor sections extends outwardly and intersects the plane of the carwheels. The plates or side floor sections which lap the central floor section are rigidly connected thereto in any suitable manner, as by bolts 25. Cross-braces or tie-straps such as 21", 21", 22", 23", and 24" are provided for the floor planking, and extend beneath the side sections as well as the center sections. 26 bolted to the straps'and to the door planking extends centrally of the car, substantial-f ly to the outer sides ofthe bumpers 10, 11; as shown, it is gained into the upper surface Abar,

of the planking. Near each end of this bar 26, a coupler bar 27 is riveted thereto.

As the car Yshown in Figures 1, 2, and 3 is intended to be used with a rotary dumping device, it is equipped with flanged depending members 30 at each side and near each end of the body, which are intended .to interlock with corresponding elements in the dumping cradle, not shown. As the lading is not obliged to slide longitudinally of the floor in dumping, itis permissible to place reinforcements for the car body within the same. These reinforcements comprise stiening angles 31 which, with the tie-straps hereinbefore referred to, serve to reinforce the bodyV of the car. Additionally, gussets 33 are connected with the inwardly disposed flanges 34 and with the vertical dan es 35 of the vertical side angles and the ang es 31 at convenient intervals along the length of the car whereby a rigid structure is provided.

As a whole, it will be seen, the floor extends in nearly a horizontal plane. As already mentioned, the ioor is reinforced at its outer sides by the side sill angles 36. f

The door is amply braced'andmade rigid, transversely, by the straps 21a, 2lb, 22h, 23", 24:b and the angles 31, which latter are preferably bolted to the straps through the planking, as shown at 32 in Fig. 3, as well as by the end walls, which are connected to the side walls. Longitudinally, 4likewise, it iseii'ectively braced by the sills`13, 14, and

36. The straps and the transverse members 31 also serve (as well as the ends) for supporting the outer floor sections from the sills floor comprising a plurality of longitudinally extendlng planks and a'plurality of longitudinally extending angles between .and lapping said planks and connected thereto with a sheathing of metal enclosing one end of said planks; the planks, angles' and sheathing beingl connected and 'adapted to cooperate in reslsting buiing Stresses.
