MINE CAR.

Application filed December 28, 1926. Serial No. 157,551.

This invention relates to cars, and more particularly to cars of the class used in coal mines and industrial plants.

The invention has to do With improve- Inents relating to (1) the truck, (2) the structure of the body and its frame, and

(3) the wheel mounting.

An object of the mvention is to provide a mine car which has a relatively low center of gravity and a high load capacity for its weight and overall dimensions.

Inother words, the invention seeks to maintain the weight and overall dimensions of the car within reasonable limits, and to provide extremely high load capacity.

Another object of the invention is to provide a car of sim le and rugged construction, the parts 0 which may be readily manufactured and assembled. As is well known, these cars are sub'ected to rough usage, and must withstan severe strains. Moreover, when used in vcoal mines, they must travel in rooms or entries which are comparatively low and narrow, and this condition prohibits increasing the height or width of the car beyond certain fixed limits.

In the accompanying drawings, there is shown a preferred embodiment of the invention, and in these drawings:

Figure 1 is a longitudinal sectional view. Figure 2 is a bottom plan view. Figure 3 is a perspective of the truck b2- fore the body is applied thereto.

Figure 4 is a fragmentary transverse sec= tion taken approximately through one of the wheels with the wheels shown in elevation.

Figure 5 is a top plan view of one of the inner truck sill bars or castings.

Figure 6 is an outer side elevational view 7 of one of the inner sill castings.

Figure 1 0 is a View similar to Figure 9, showing st1ll another floor construction.

The car comprises, broadly, two units, I

namely, a truck unit T (Fig. 3) havin wheels independently mounted on stu axles, and a body unit B, which may be formed with the truck in the construction of the car, or separately formed and then mounted on the truck.

It will be understood, of course, that although the parts are referred to as units, they are described in this manner simply for convenience, and this mode of description is not to be interpreted as limiting the invention to a car in which the body and truck are separately formed or are separable from one another, as units. I

Referring to the truck unit (Figure 3 the same comprises side sills or bars which are preferably cast, and are arranged in pairs at opposite sides of the truck. Wheels 10 are positioned between each pair of sill bars and are mounted upon stub axles 11. In the present instance, the sill bars of each air are cast separately, and in the drawmgs, 12, 13, designate the outer members of each pair. These sill bars are connected by cross girts, which extend through the inner sill bars to. which they are secured, to the outer sill barsto which they are also secured.

The cross girts in the present instance, comprise a central channel beam 17 and end beams or cross bars 18, which are preferably of angular form in cross section.

The end cross girts are arranged outside the wheels, and are supported upon longitudinally extending shoulders of the lugs 12', 13, 14 and 15', which constitute cutaway portions at the ends ofthe sill bars. These lugs or shoulders extend longitudinally of the sill bars, and are arranged in substantially the same plane with the central cross girt 17 so that the end cross bars may serve to support the floor of the car in a 'plane below the top surfaces of the sill bars or castings;

As illustrated in Figures 1 and 3, the end beams are of angular cross section, having a horizontal flange resting upon the legs 12', 13, 14', 15' and a vertical flange ex- }:ending downwardly at the ends of these I An additional floor supporting means is provided in the form of inwardly projecting webs or platform members 19, formed or cast integrally with the inner sill bars and arranged in substantially the same horizontal plane with the cross beams 17, 18. The truck as thus constructed, is adapted to receive the body unit which comprises, generally, a floor 20, (Figs. 1, 3 and 4) bolted or otherwise secured to the cross beams 17, 18 and to the supporting webs 19 extending inwardly from the two inner sill bars. These means for side wall braces extending upwardly and laterally. In order to increase the width of the car, and provide a lateral floor extension beyond the outer sill bars 12, 13, angle members 26 are secured, as by riveting, or otherwise, to the side faces of the outer sill bars and have laterally or outwardly extending horizontal flanges 27 (Fig. 4) to which may be secured outwardly extending floor plates 28. These floor plates are joinedby an angle iron 29 to the side walls 30, which are reinforced by the braces 25. At each end of the car, the floor is provided with an extension plate 31, which is supported by cross beams 18 and by transverse channel or angle members 32 joined at their ends to the side angle or channel members 26.

It will be understood that the side channel members 26 and the end transverse channels 32, constitute a body base frame structure which is supported from the truck by the connection of the side channels with the outer sill castings. The body end walls may be of any suitable construction, and one of the same may be hinged, if desired, to provide a gate. 1

Referring to Fi ure 7, there is shown a somewhat modified structure in that the side Walls 30' are joined to the lateral extensions 2 8 of the floor by means of channel members 29' instead of the angle 29 illustrated in Figure 4.

The construction illustrated in Figure 8 shows the angle 29 corresponding to the angle 29 (Fig. 4) arranged outside the body instead of interiorly thereof.

In Figures 9 and 10 there is shown somewhat varied body constructions wherein the central floor plate 20 is arranged beneath the integral supporting lugs 19 on the inner sill bar castings 14, 15 and beneath the end cross beams 18' which, instead of having their horizontal flanges arranged above the lugs 12, 13 etc., are arranged so that the horizontal flanges are positioned beneath the lugs 12, 13, 14, 15 with the vertical flanges extending over the end surfaces of the lugs. With this arrangement, the floor extension plates 31 are secured to the central plate 20 beneath the horizontal flange of the cross beam 18.

Figure 10 illustrates still another modification different from that illustrated in Fig. 9, in that the cross sectional shape of the end beam 18 is varied. In this instance, a T-beam 38 is secured to the longitudinally extending lugs 12', 13, etc., and has flanges 38, 38 extending horizontally in opposite directions having secured thereto, respectively, the extension plates 31 of the floor and the central floor plate v20.

Referring to the wheel mounting shown most clearly in Figures 4, 5 and 6, it will be understood, of course, that any suitable construction may be utilized for mounting the wheels, although the stub axle type of structure is preferred with a truck of the character disclosed. Each sill casting is formed with inverted substantially U-shaped axle recess 40, open at its lower end to permit the axle 11 to be fitted therein. ,When a nonrotating stub axle is received, the upper end 41 of each recess may be curved to form a semi-circular clamping element or half bearing adapted to cooperate with a half bearing 42 formed on a saddle member which is provided with a transversely extending securing element 43 extending across the open end of the recess 40, andhaving openings adapted to receive downwardly projecting lugs 44. The lugs 44 have transverse openings 48 into which may be inserted securing bolts 46 adapted to retain the saddle element and half bearing in position.

As illustrated in the drawing, this wheel -mounting is utilized with a stub axle of the fixed or non-rotating type, and as will be understood, the wheel has fitted therein a roller or ball bearings (not shown). When it is necessary to drop a wheel for replacement of the axle or repair of a bearing, it is simply necessary to release the securing bolts, and by lowering the saddle member, the axle may be removed with its wheel. It will be understood that the axle is of the hollow lubricant containing type, a detachable lubricant filling 49 being provided at its end and being adapted for removal, if

necessary, when the axle is to be dropped. It will be understood, of course, that the construction illustrated and described in detail may be varied materially without departing from the invention, which is defined in the following claims.
